Mobile terminal device

Technical field

The present invention relates to a portable terminal device provided with a close proximity communication function for contactlessly communicating with another device located at a relatively short distance, and in particular to a user interface for user's input operation. About. Background art

For example, in portable terminal devices such as portable telephone devices and personal digital assistants (PDA), there is a restriction that the operation unit and the display unit are relatively small in order to generally prioritize the miniaturization of the device. There is a problem that the user's input operation is difficult. Therefore, for mobile terminal devices, various techniques related to user interfaces for improving the operability regarding the user's input operation have conventionally been proposed.

For example, Patent Document 1 proposes that a user taps a device to answer a call. Further, Patent Document 2 proposes stopping the ringing sound when the user strikes the device. Further, Patent Document 3 proposes calling a function according to a pattern (strength or interval) to be hit when the user hits the device. Further, Patent Document 4 proposes switching to the off-hook state when the user strikes the device. In addition, Patent Document 5 proposes that when the user strikes the device, the response is switched to the hold state.

That is, since the device executes the function in response to the user's tapping operation, it is not necessary for the user to operate the small button on the operation unit of the device, and the operability can be expected to be improved. However, since the tapping operation is extremely simple, the number of functions that can be performed in response to that operation is practically limited to only about one, and it can not always be said that the utility value is high. It is. For example, if the type of pattern to be struck is classified into a plurality of types as in Patent Document 3, the user must remember in advance the differences between the patterns, which may make the operation cumbersome. .

Among recently developed mobile terminal devices, there are devices capable of proximity communication in which communication is performed without contact with another device at a short distance. For example, "FeliCa (registered trademark)" Non-contact communication unit having the function of non-contact IC card is mounted on the device to perform non-contact communication, and also to have value information which has a monetary value in advance on the memory of the non-contact communication unit, That is, those that hold electronic money and realize payment functions are becoming popular.

A case will be considered in which an input operation is performed when executing various functions using proximity communication in such a mobile terminal device. In the input operation of the conventional portable terminal device, the user can select a desired function from a list of menus displayed on the screen of the device, or operate a dedicated button provided on the device. It is designed to perform input operations. Also, in the portable terminal device equipped with the current contactless communication unit, the contactless communication unit of the portable terminal device operates passively and receives payment processing etc. forcibly from the reader / writer, like the contactless IC card. There is something like

[0007] In a portable terminal device equipped with a non-contact communication unit, when performing settlement processing of a non-contact IC power function by proximity communication, the user actually specifies the main body of the portable terminal device. It is necessary to hold it close to the reader / writer existing at the position of. For this reason, when performing an input operation in close proximity communication, the operation is performed in a state where the portable terminal device is considerably away from the user's face. Therefore, during payment processing, it is difficult for the user to select a menu etc. while viewing the display on the screen of the portable terminal device. It is difficult to get used to operating a specific button on At present, means are used such as displaying information on the display unit on the reader / writer side and notifying the execution result of processing with sound.

The mobile terminal device 100 of the present embodiment shown in FIG. 1 has a function of a mobile telephone device, and includes a terminal body 10 and a non-contact communication unit 20 which is an IC card unit having a proximity communication function. . The terminal main body 10 includes a vibration detection unit 11, a vibration processing unit 12, a data storage unit 13, a data interpretation unit 14, a display unit 15, a display control unit 16, a control unit 17, and a timer 18. And a portable terminal interface (I / F) 19. In FIG. 1, only some of the main elements of the portable terminal device are shown, and as in a general portable telephone device, a predetermined wireless base station is shown. Wide-area communication function for wireless communication with any other terminal via Internet, camera function for imaging the subject, e-mail function for sending and receiving e-mail, network content browsing function, etc. The following components are provided in the terminal body 10. In addition, various control functions on the terminal main unit 10 can be realized by a dedicated electric circuit.

It can also be realized by a software program executed by a control computer.

Further, in the non-contact communication unit 20, a data storage unit 21, an access management unit 22, a buffer 23, a carrier transmission / reception unit 24, a function stop processing unit 25, and an IC card interface (I / F). 26 and an IC card control unit 27.

The vibration detection unit 11 of the terminal main body 10 is a sensor for detecting mechanical vibration applied to a housing or the like of the portable terminal device 100 by a user's tapping operation or the like. The vibration processing unit 12 recognizes the user's tapping operation by processing the signal detected by the vibration detection unit 11. The data storage unit 13 is a memory for temporarily holding received data, data to be transmitted, and the like. The data interpretation unit 14 divides the packet of the received data into a header and a data body, analyzes the content of the data, and executes various processing according to the result.

The display unit 15 displays various information in the mobile terminal device 100. For example, the display unit 15 displays a list of menus of functions that can be executed on the mobile terminal device 100 or displays the balance, payment amount, etc. of electronic money held in the non-contact communication unit 20. The display control unit 16 performs processing of information displayed on the display unit 15 and drive control of a display device of the display unit 15.

The control unit 17 has a function of an execution control unit, and executes various controls of each unit in the entire portable terminal device 100. The timer 18 is for measuring the time used for various operations. The portable terminal interface 19 is an interface for connecting the terminal body 10 and the non-contact communication unit 20 and communicating between the two.

The data storage unit 21 of the noncontact communication unit 20 is a non-volatile memory for holding identification information of the IC card unit itself, value information such as electronic money, and the like. The access management unit 22 restricts access to information stored in the data storage unit 21. , And performs processing such as authentication processing and encryption / decryption. The knocker 23 is a memory for temporarily holding data transmitted and received by the noncontact communication unit 20.

The carrier wave transmitting / receiving unit 24 is for performing near field communication (proximity communication) by this carrier wave using a high frequency radio signal (carrier wave of electromagnetic wave), and includes an antenna and a transmitting / receiving circuit. . For example, assuming near field communication (Near Field Communication: NFC), the range in which the carrier wave transmitting / receiving unit 24 can communicate is about 10 cm. In the case of a general terminal, close proximity communication is performed using a carrier wave transmitted by the reader / writer as the other device, but in this embodiment, close proximity communication can be performed even between the terminals. The carrier wave transmitting / receiving unit 24 has a function of transmitting a carrier wave as in the case of the reader / writer.

The function stop processing unit 25 is for stopping the function of the non-contact communication unit 20 when proximity communication is not performed or under a predetermined condition. The IC card interface 26 is an interface for communicating between the non-contact communication unit 20 and the terminal body 10. The IC card control unit 27 executes overall control of the non-contact communication unit 20.

Next, a specific example of the characteristic operation of the mobile terminal device 100 of the present embodiment will be described with reference to FIG. FIG. 2 shows the operation of the transmitting terminal having a function of transmitting a carrier wave.

In step S11 of FIG. 2, it is identified whether or not the user's tapping operation has been detected. Specifically, when the vibration detection unit 11 detects mechanical vibration having a predetermined strength or more, it can be considered that the user's tapping operation is detected. Of course, it is good even if it distinguishes using not only strength but also change pattern of vibration strength.

In step S12, the carrier wave transmitting / receiving unit 24 of the own device starts transmitting the carrier wave in order to confirm whether the other device (terminal or reader / writer) for close proximity communication is present in the vicinity of the own device. . When there is a partner apparatus equipped with a proximity communication function near the host apparatus, the partner apparatus may use this carrier wave to secure operating power and transmit and receive signals using this carrier wave. it can.

In step S13, in order to confirm whether or not there is a partner apparatus, a carrier confirmation command (polling) determined in advance is sent on the carrier wave. In step S14, it is confirmed whether or not a response of the other device is detected in response to the other party confirmation command sent in step S13. If a response is detected, the process proceeds to step S17, and if no response is received, the process proceeds to step S15.

In step S15, it is determined whether or not a predetermined time (for example, 3 seconds) has elapsed since the command for partner confirmation is first sent in step S13. If the predetermined time has not elapsed, the process returns to step S13, and the transmission of the other-party confirmation command is continued. If there is no response from the partner apparatus before the predetermined time has elapsed, the process proceeds to step S16.

In step S16, transmission of the carrier wave from the carrier wave transmitting / receiving unit 24 is stopped. Therefore, if the response from the other device is not detected for a predetermined time only by detecting the tapping operation (or mere vibration) in step S11, no special operation is performed.

[0044] When the P utter operation is detected and a response from the other device is detected, it is considered that the authentication is successful and the execution condition is satisfied, and in step S17, the proximity communication using the carrier wave transmitting / receiving unit 24 Permits near field data communication according to, and permits a predetermined operation using this near field data communication.

Next, an actual operation example of the present embodiment will be described with reference to FIG. In the example shown in FIG. 3, it is assumed that proximity communication is performed between two portable terminal devices 100A and 100B. In this example, the non-contact communication unit 20A has a carrier wave transmission function (reader / writer function) in one of the portable terminal devices 100A (sender side), but the other (receiver side) In the terminal device 100B, the non-contact communication unit 20B does not necessarily need to have a carrier wave transmission function, and may have only a reception function (card function) to receive and communicate the carrier wave of the other device.

Here, the case of transferring image data is illustrated. First, in the portable terminal device 100A which is the transfer source terminal, image data to be transmitted is prepared in the terminal main body 10A and displayed on the display unit 15 (S101). The display screen of the display unit 15 at this time is as shown in FIG. 4 (a), for example. Then, the user brings the two portable terminal devices 100A and 100B close to each other, and performs an operation of tapping the transfer source portable terminal device 100A.

At this time, when the vibration detection unit 11 of the terminal body 10A detects a vibration in a state where the mobile terminal device 100B of the other party is detected (S102), it is assumed that the authentication is successful and the execution condition is satisfied. Then, execution of data transfer by close proximity communication is started. The terminal body 10A sends a request to start the reader / writer function to the noncontact communication section 20A (S103), and transmits it to the noncontact communication section 20A, then starts the reader / writer function and outputs the carrier wave of the near field communication ( S104). On the other hand, in the portable terminal device 100B which is the transfer destination terminal, the non-contact communication unit 20B transmits the card function in the standby state and starts the card function to receive the carrier wave (S105).

In the portable terminal device 100A, a data writing request including information on transmission data type is transmitted from the terminal body 10A to the non-contact communication unit 20A (S106), and the proximity from the non-contact communication unit 20A of the portable terminal device 100A The data writing request is transmitted to the non-contact communication unit 20B of the portable terminal device 100B by communication (S107). The non-contact communication unit 20B of the mobile terminal device 100B stores the received data in the buffer 23 (S108). Then, the non-contact communication unit 20B notifies the terminal body 10B of data reception (S109). The terminal body 10B transmits a data read request to the non-contact communication unit 20B (S110), and fetches data of the transmission data type from the buffer 23 (Sl l l). Then, the display unit 15, which is receiving data, displays a screen during data transfer (S112). The display screen of the display unit 15 at this time is, for example, as shown in FIG. Similarly, the mobile terminal device 100A of the transfer source may display a screen during data transfer.

When data reception is successful in the portable terminal device 100B, the non-contact communication unit 20B notifies the portable terminal device 100A of a response of success of data writing (S113), and the response of the success of data writing is non-contact communication. It is sent from the unit 20A to the terminal body 10A (S114). Subsequently, a data writing request including information of actual data is sent to the terminal body 10A power contactless communication unit 20A (S115), and the contactless communication unit 20A of the mobile terminal device 100A performs near-field communication of the mobile terminal device 100B. The data write request is transmitted to the noncontact communication unit 20B (S116). The non-contact communication unit 20B of the mobile terminal device 100B stores the received data in the buffer 23 (S117). Then, repeat this procedure until the transfer of the target image data is completed.

When the reception of the image data is completed, the portable terminal device 100 B of the transfer destination displays the received image data on the display unit 15 (S 118). At this time, for example, the image data is displayed on the display screen as in FIG. 4 (a). In the mobile terminal device 100A of the transfer source, image data When the transmission is completed and a response to the data writing success is received from the portable terminal device 100B, the display on the display unit 15 is erased (S119).

That is, when an operation to strike is performed in a state in which the two mobile terminal devices 100A and 100B approach each other, step S17 in FIG. 2 is executed, and data transfer by proximity communication is permitted. The specific contents of the operation sequence as shown in FIG. 3 can be appropriately changed in accordance with various needs and communication standards according to the application and the like.

In the operation example shown in FIG. 2 described above, it is assumed that the non-contact communication unit 20 of the mobile terminal device 100 has a carrier wave transmission function, but a general non-contact communication IC card is It does not have a carrier wave transmission function, and performs near-field communication using the carrier wave transmitted by the reader / writer that is the partner device. If the carrier wave transmission function is not installed, the mobile terminal device 100 may execute the operation shown in FIG. 5 instead of the operation shown in FIG. 5 (a) shows the operation when the carrier wave is detected in the non-contact communication unit, and FIG. 5 (b) shows the operation when the user's tapping operation is detected in the terminal body.

In step S21 of FIG. 5 (a), it is determined whether or not the non-contact communication unit 20 of the own device detects a carrier wave from the other device (reader / writer or terminal). If the distance between the own apparatus and the partner apparatus is short and the partner apparatus is transmitting a carrier wave, the carrier wave can be detected in step S21.

In step S22, the carrier wave from the other device is modulated by a signal for responding to the polling from the other device, and this signal is sent out. In step S23, time information corresponding to the current time 亥 IJ is recorded. As a result, the fact that the partner apparatus for near field communication existed in the vicinity of the own apparatus is held as a record.

On the other hand, in step S26 of FIG. 5 (b), it is identified whether or not the user's tapping operation has been detected. Specifically, when the vibration detection unit 11 detects mechanical vibration of a predetermined strength or more, it can be considered that the user's tapping operation is detected.

If an operation to strike is detected in step S26, a predetermined time in the past is determined in the next step S27.

Investigate whether or not the partner device for proximity communication is detected within (for example, 3 seconds). Specifically, the force S to be checked can be obtained by comparing the time recorded last in step S23 with the current time. If a partner device for proximity communication is detected within the past predetermined time, From step S27, the process proceeds to step S28. In step S28, the near field data communication by the near field communication using the carrier wave transmitting / receiving unit 24 is permitted, and the operation scheduled to use this near field data communication is permitted.

Further, in step S24 of FIG. 5 (a), whether or not a predetermined operation involving short distance wireless data communication is permitted is checked. If an operation to be struck when a partner apparatus for close proximity communication exists in the vicinity of the own apparatus is detected, the operation is permitted in step S28 described above, so the process proceeds from step S24 to step S25. On the other hand, operation is not permitted if there is only a partner device for near-field communication in the vicinity of the own device, and operation is not permitted if only a tapping operation is detected. Then, in step S25, a predetermined operation involving short distance wireless data communication is executed.

As described above, in the present embodiment, when the user performs an operation of tapping on the portable terminal device, or before or after that, the partner device for proximity communication (for example, a reader / writer for a non-contact communication IC card) And only when there is a non-contact communication function) in the vicinity (within the communicable range), it performs the predetermined operation that involves that communication. By this, when performing a predetermined operation by proximity communication, in this case, data communication, the user only hits the terminal case or hits the terminal case against some object to generate mechanical vibration. Thus, the user can easily complete the input operation for confirmation, and the terminal can perform processing without referring to the display on the screen and performing selection operation or special button operation.

In addition, when the user unintentionally knocks his or her terminal against an obstacle or drops the terminal, the terminal may be mistaken as an operation to strike the mechanical vibration generated thereby. May be recognized. However, since there is a high possibility that no other device for near communication exists in the vicinity at that time or immediately before or after that time, data communication and the like will not be performed. As a result, it is possible to prevent the operation that the user did not intend, and secure the safety against the outflow of data.

Therefore, according to the present embodiment, when performing various functions using proximity communication by the non-contact communication unit, it is possible to easily operate the functions according to the user's intention, It is possible to improve the quality.

Second Embodiment FIG. 6 is a sequence diagram showing an operation example of near field communication using the portable terminal device according to the second embodiment. FIG. 7 is a view showing an example of a display screen in the second embodiment.

The second embodiment is a modification of the first embodiment, and the basic configuration of the mobile terminal device 100 is the same as that of the first embodiment shown in FIG. However, in the second embodiment, the noncontact communication unit 20 of the portable terminal device 100 does not have a carrier wave transmission function, and the data storage unit 21 of the noncontact communication unit 20 has value information such as electronic money. Shall be held.

Here, an actual operation example of the present embodiment will be described with reference to FIG. In the example shown in FIG. 6, it is assumed that close proximity communication is performed between the portable terminal device 100 and the partner device 200. As a specific partner device 200, for example, a reader / writer mounted on various devices that require a monetary payment such as an automatic ticket gate for a train, a game machine, a pachinko machine, and a vending machine is used. Since the mobile terminal device 100 is not equipped with a carrier wave transmission function, the mobile terminal device 100 executes the same operation as that of FIG. 5 described above.

Here, the case of executing settlement processing such as electronic money is exemplified. First, when the user brings the portable terminal device 100 close to the partner device 200 having a reader / writer function, the portable terminal device 100 starts a card function in the non-contact communication unit 20 in a standby state and receives a carrier wave ( S301). When the partner apparatus 200 detects the mobile terminal apparatus 100 of the communication partner, the data writing request including the IC command of unlocking related to the settlement function of the non-contact communication unit 20 and the information of the message is transmitted via the proximity terminal It transmits to the non-contact communication part 20 of (S302). Value information such as electronic money stored in the data storage unit 21 on the noncontact communication unit 20 is normally locked for security reasons so that it can not be accessed. In order to do this, it is necessary to unlock the payment function of the non-contact communication unit 20 in advance.

The non-contact communication unit 20 of the portable terminal device 100 stores the received data in the buffer 23 (S 303). Then, the non-contact communication unit 20 notifies the terminal body 10 of data reception (S304). The terminal body 10 transmits a data read request to the non-contact communication unit 20 (S305), and fetches data of an IC command for unlocking or a message from the buffer 23 (S306). Then, the non-contact communication unit 20 transmits a response to data reception success to the partner apparatus 200. Then, the display unit 15 displays a confirmation screen for electronic money payment on the display unit 15, and requests input from the user (S308). The display screen of the display unit 15 at this time is, for example, as shown in FIG. This display screen is used to confirm the payment of electronic money.

At this time, when the user holds and strikes the portable terminal device 100 and detects the tapping operation by the vibration detection unit 11 of the terminal main body 10 as in the operation shown in FIG. 5 (S 309) In this case, since the carrier wave from the partner apparatus 200 is detected, it is recognized that the authentication is successful and the execution condition is satisfied, and it is recognized that the user's confirmation has been obtained. Then, an IC command instructing lock release is transmitted from the terminal main body 10 to the non-contact communication unit 20 (S310). In response to the IC command for unlocking, the non-contact communication unit 20 unlocks the operation such as reading and writing to the data storage unit 21 in the IC card unit, and switches to a state where the value information can be accessed (S311) . Then, a response indicating that the lock has been released is sent back to the terminal body 10 (S312).

In this state, the partner apparatus 200 transmits, as an IC command, a predetermined value operation command related to electronic money payment to the non-contact communication unit 20 of the portable terminal apparatus 100 existing in the vicinity (S 313). By the clue operation command, reading and writing of data from the non-contact communication unit 20 by the non-contact communication are performed, and value reduction processing is performed (S 314). When the value reduction processing ends normally, the non-contact communication section 20 transmits a processing success response to the partner apparatus 200 (S315). When the lock is not released in the non-contact communication unit 20, the processing related to the crown information is rejected, and the access from the partner apparatus 200 fails.

In addition, the terminal main body 10 of the portable terminal device 100 receives a response of the IC command for releasing the lock and waits for a certain period of time (S 316), and after a certain period of time elapses, the operation regarding the function of the noncontact communication unit 20. Send a lock IC command (S317). Then, the non-contact communication unit 20 executes again locking of operations such as reading and writing to the data storage unit 21 in the IC power unit (S318).

In the above operation example, when the lock of the operation of the data storage unit 21 in the IC card unit is released by vibration detection, the lock is applied again after a predetermined time has elapsed, but other methods may be used. Is also conceivable. For example, perform an operation that the user strikes again after unlocking If a vibration is detected, the lock may be applied again. As a result, the user can unlock the IC card only for the intended period, and the security can be improved.

As described above, in the present embodiment, immediately after the user strikes the portable terminal device, the portable terminal device is brought close to the other device, or the portable terminal device is struck close to the other device. Alternatively, by placing the portable terminal device in the vicinity of the other device to generate mechanical vibration, the settlement process using electronic money or the like is executed. Therefore, when trying to perform a predetermined operation by proximity communication, in this case settlement processing, the user strikes the terminal casing or applies the terminal casing to some object to generate mechanical vibration. Only then, the input operation for confirmation can be easily completed, and the terminal can perform processing without referring to the display on the screen or operating a special button. However, if, for example, the user does not intend to confirm the payment processing, as in the case where the user unknowingly places the mobile terminal on an object or drops the mobile terminal, the mobile is not mobile. Since the other device does not exist in the vicinity of the terminal device, unlocking of the non-contact communication unit can prevent payment processing unintended by the user and security is secured.

FIG. 8 is a flowchart showing an operation example of the mobile terminal device in the third embodiment. FIG. 9 is a sequence diagram showing an operation example of near field communication using the portable terminal device according to the third embodiment. FIG. 10 is a view showing an example of a display screen in the third embodiment.

The third embodiment is a modification of the second embodiment, and the basic configuration of the mobile terminal device 100 is the same as that of the first embodiment shown in FIG. Also in the third embodiment, as in the second embodiment, the non-contact communication unit 20 of the portable terminal device 100 does not have a carrier wave transmission function, and the data storage unit 21 of the non-contact communication unit 20. It is assumed that value information such as electronic money is held.

Here, a specific example of the characteristic operation of the mobile terminal device 100 of the present embodiment will be described with reference to FIG. Fig. 8 (a) shows the operation when the carrier wave is detected in the non-contact communication unit, and Fig. 8 (b) shows the operation when the user's tapping operation is detected in the terminal body. In step S51 of FIG. 8 (a), it is determined whether or not the non-contact communication unit 20 of the mobile terminal device 100 has detected a carrier wave from the other device (redirector). If the partner apparatus exists in the vicinity of the own apparatus and the partner apparatus is transmitting a carrier wave, the carrier wave is detected, and the process proceeds to the next step S52.

In step S 52, the non-contact communication unit 20 receives the data sent from the other device and records the data in the buffer 23. Also, in the next step S53, the non-contact communication unit 20 communicates with the terminal body 10.

On the other hand, in step S 58 in FIG. 8 (b), it is determined whether or not the user's tapping operation is detected in the terminal main body 10 ^. If a user's tapping operation is detected, in this case, the carrier wave from the partner apparatus 200 is detected, so it is considered that the authentication is successful and the execution condition is satisfied, and the process proceeds to the next step S59. . In step S59, it is checked whether a lock release request has been received from the non-contact communication unit 20. Here, when the terminal body 10 receives a lock release request from the non-contact communication unit 20, the terminal body 10 transmits a lock release command to the non-contact communication unit 20 in the next step S60.

At this time, the non-contact communication unit 20 confirms whether or not the unlocking command has been received from the terminal main body 10 in step S54 of FIG. 8 (a). When the unlock command is received, the process proceeds to step S54 using step S54.

In step S 55, in accordance with the lock release command received from the terminal main body 10, the non-contact communication unit 20 unlocks access to value information in the data storage unit 21. However, in the present embodiment, the value which can be reduced at one time is limited to a fixed amount (for example, 100 yen equivalent). Even if there is a sufficient amount of value (electronic money) in the data storage unit 21, the upper limit of the discount that can be reduced by unlocking is limited to a predetermined fixed amount.

Then, in step S56, when the value operation command is received from the other device, the settlement function is unlocked in the previous step S55, so the value reduction processing is executed according to the instruction from the other device. Do. However, the value to be reduced is limited to a fixed amount.

When the value reduction process is completed in step S56, or the settlement function is unlocked. When a predetermined time has elapsed since the division, the process proceeds to step S57, and the lock on the value information on the data storage unit 21 is executed again.

In the terminal main body 10, when an operation is detected, the operation proceeds from step S58 to S59 and proceeds to S60. Therefore, each time a tapping operation is detected, a lock release command is issued to the non-contact communication unit 20. Send out. For this reason, for example, as in the case of paying while counting cash coins one by one, it is possible to make a payment S from the electronic money every time the mobile terminal device 100 is hit.

Next, an actual operation example of the present embodiment will be described with reference to FIG. In the example shown in FIG. 9, as in the case of FIG. 6, it is assumed that proximity communication is performed between the mobile terminal device 100 and the partner device 200 to execute payment processing.

As in the second embodiment described above, a request for writing data including an IC command for unlocking regarding the settlement function of the non-contact communication unit 20 is issued from the partner apparatus 200 to the portable terminal apparatus 100. A request for electronic money is transmitted to the noncontact communication unit 20 (S501). Here, it is requested to pay electronic money of 100 yen each from the other device 200.

The portable terminal device 100 executes acceptance processing of the settlement function as in the second embodiment, displays a confirmation screen of electronic money settlement on the display unit 15, and requests an input from the user (S500) ). The display screen of the display unit 15 at this time is, for example, as shown in FIG. This display screen shows the value 100 yen paid in one operation and the current balance 2000 yen, and confirms the payment by electronic money.

At this time, when the user holds and strikes the portable terminal device 100 and the tapping operation is detected by the vibration detection unit 11 of the terminal main body 10 (S 503), the carrier wave from the partner device 200 is detected. Therefore, it is recognized that the user's confirmation has been obtained, and the settlement function of the non-contact communication unit 20 is unlocked as in the second embodiment. Then, a response for permitting the payment of the electronic money is transmitted to the partner apparatus 200 (S 504). When receiving the response from the portable terminal device 100, the partner device 200 transmits data communication by close proximity communication to the non-contact communication unit 20 of the portable terminal device 100 as in the second embodiment, and The amount is charged by reducing the value by a fixed amount (100 yen) (S505). As a result, an electronic money payment check of 100 yen is executed in one tapping operation. Then, the processing of the above S501 to S505 is repeated. In the case of the second operation, the display screen of the display unit 15 is, for example, as shown in FIG. 10 (b), and the balance is reduced by 100 yen from the previous time. At this time, the user can instruct electronic money payment while checking the remaining amount each time.

As described above, according to the present embodiment, as the user inserts a hot coin while checking each time the user performs an operation to strike the portable terminal apparatus, the electronic money is added by a predetermined amount. Ne payment can be made. Therefore, it is possible for the user to easily grasp the payment amount and to recognize the payment amount by the number of operations without looking at the amount display on the display screen. In addition, it is possible to prevent large-scale payments from being made unintentionally, such as large-scale payments being made at one time.

As described above, by applying the present invention to a portable terminal device provided with a proximity communication function, the user can refer to the display on the screen without performing selection operation or operating a specific button. It is possible to perform instruction operation and confirmation operation by extremely simple tapping operation, and to execute a predetermined function S. Such a tapping operation is possible in extension of the operation to bring the non-contact communication unit of the mobile terminal device close to the other device such as a reader / writer or other terminal, and since the troublesome operation is not necessary, the operability is good. is there. In addition, the user can confirm execution of data transfer, electronic money settlement, etc. by intuitive operation. At this time, the non-contact communication unit can execute close proximity communication by receiving and activating a carrier wave from the partner apparatus or transmitting a carrier of its own apparatus to activate the partner apparatus.

Moreover, since processing is not executed when the other device for close proximity communication does not exist in the vicinity, it is possible to prevent processing from being performed against the user's intention, and it is possible to prevent information leaks such as electronic money, etc. Sufficient safety against rewriting can be ensured. Therefore, the user can easily operate the function according to the user's intention, and the operability can be improved.
