The present invention relates to a family of communications equipment having a plurality of lines, and more particularly to a facsimile apparatus.
The prior art techniques for facsimile apparatuses include the one described in Japanese Unexamined Patent Application Disclosure HEI 5-219275, for example. Dual communication facsimile apparatuses as disclosed therein may be efficiently used since the two lines may be used individually for transmission and reception at the same time.
However, even with such dual communication facsimile apparatuses which allow conversation and/or facsimile transmission to be performed individually over two lines, a busy signal is produced whenever the telephone is dialed for additional conversation or facsimile transmission with the same end over a second line if a first line has already been occupied due to conversation or facsimile transmission.
Here, the operator must wait until the receiver is freed from the busy state when the operator dials, whereas when the telephone is automatically controlled, it must be ready for redialing, which may result in the second line being reserved and prevent the line from being operated otherwise.
It is an object of the present invention to provide a facsimile apparatus with increased usability, the facsimile apparatus being designed so that the dialing operation is controlled to increase the usability of the facsimile apparatus when a receiving end, which has been connected for conversation or facsimile transmission over a first line, is attempted to be additionally connected for separate conversation or facsimile transmission over a second line.

Figure 1 is a block diagram illustrating a control operation according to the invention, wherein 1 indicates a controller unit, 2 is an input-number storage unit, 3 indicates an operator unit, 4 indicates a personal computer I/F
unit, 5 is a transmitter-side information storage unit, 6 indicates a receiver unit, 7 is a dial-information storage unit, 8 is a line controller unit, 9 is a dialing unit, 10, 11 and 12 are a display unit, buzz unit and voice-processing unit, respectively and 13 is a communication-management-data storage unit.
The control operation illustrated in Figure 1 will now be described again with reference to a flow chart related to the drawing.
In the flow chart of Figure 2, the subscriber number of the receiving end connected over line 1 is stored in the dial information storage unit 7 of the apparatus. Here, the number input by the operator with the operator unit 3 is stored in the input-number storage unit 2 on a digit-by-digit basis. The controller unit 1 compares the two numbers on a digit-by-digit basis starting with the first digits (S201 through S207).
Here, control codes such as a pause code which have no direct relationship with the telephone numbers, when found, are skipped, and the next digit is considered in the comparison. When the controller unit 1 finds the first mismatching digit, on determining that the destination number is not the same, the data stored in the input-number storage unit is sent to the dialing unit 9 (S212) which in turn issues a command matching the received data to the line controller unit 8, and a signal matching the received command is output to line 2 from the line controller unit 8. Here, the comparison for the number input by the operator is terminated. In cases where the result of the comparison shows that the two numbers completely match, the controller unit 1 erases the data stored in the input-number storage unit 2, without sending it to the dialing unit 9, and notifies the display unit 10, the buzz unit 11 and the voice-processing unit 12 that the apparatus has already been connected to the receiving end, and the respective units perform their own processing depending on the notification (S208 through S210).
In the flow chart of Figure 3, the subscriber number of the receiving end connected over line 1 is stored in the dial information storage unit 7 of the apparatus. When the controller unit 1 accesses the communication management data storage unit 13 and finds a communication to be carried out, the data on the destination number of the communication is read from the communication management data storage unit 13 and is compared with the data stored in the dial information storage unit 7 (S301 through S307).
Here, control codes such as a pause code which have no direct relationship with the telephone numbers, when found, are skipped, and the next digit is considered in the comparison. When the controller unit 1 finds the first mismatching digit, on determining that the destination number is not the same, the destination number which is stored in the communication management storage unit 13 is sent to the dial unit 9 (S311) which in turn issues a command matching the received data to the line controller unit 8, and a signal matching the received command is output to line 2 from the line controller unit 8. In cases _ $ _ where the result of the comparison shows that the two numbers completely match, the controller unit 1 waits until line 1 is freed, without carrying out the communication (S308 through S309).
In the flow chart of Figure 4, the subscriber number of the receiver connected over line 1 is stored in the dial information storage unit 7 of the apparatus. Here, the data on the dialing information received from the personal computer is stored in the input-number storage unit 2 via the personal computer I/F unit 4. The controller unit 1 compares the data with the data stored in the dial information storage unit 7 (S401 through S407).
Here, control codes such as a pause code which have no direct relationship with the telephone numbers, when found, are skipped, and the next digit is considered in the comparison. When the controller unit 1 finds the first mismatching digit, on determining that the destination number is not the same, the data stored in the input-number storage unit 2 is sent to the dial unit 9 (S411 ) which in turn issues a command corresponding to received data to the line controller unit 8, and a signal corresponding to the received command is output to line 2 from the line controller unit 8. In cases where the result of the comparison shows that the both numbers completely match, the controller unit 1 erases the data stored in the input-number storage unit 2, without sending it to the dialing unit 9, and sends a signal indicating that the line is busy to the personal computer via the personal computer I/F unit 4 (S408 through S409).
In the flow chart of Figure 5, the information on the other end connected over line 1 which has been initiated by the other end is received from the other end and stored in the transmitter-side information storage unit 5 via the receiver unit 6. Here, the number input by the operator with the operator unit is stored in the input-number storage unit 2 on a digit-by-digit basis. The controller unit 1 compares the two numbers on a digit-by-digit basis starting with the first digits (S501 through S507).
Here, control codes such as a pause code which have no direct relationship with the telephone numbers, when found, are skipped, and the next digit is considered in the comparison. When the controller unit 1 finds the first mismatching digit, on determining that the destination number is not the same, _g_ the data stored in the input-number storage unit 2 is sent to the dialing unit (S511 ) which in turn issues a command corresponding to the received data to the line controller unit 8, and a signal corresponding to the received command is output to line 2 from the line controller unit 8. No further comparison is made for the number input by the operator. In cases where the result of the comparison shows that the both numbers completely match, the controller unit 1 erases the data stored in the input-number storage unit 2, without sending it to the dialing unit 9, notifies the display unit 10, the buzz unit 11 and the voice-processing unit 12 that the apparatus has already been connected to the receiver, and the respective units perform their own processing depending on the notification (S508 through S510).
In the flow chart of Figure 6, the information on the other end connected over line 1 which has been initiated by the other end is received from the other end and stored in the transmitter-side information storage unit 5 via the receiver unit 6. When the controller unit 1 accesses the communication management data storage unit 13 and finds a communication to be carried out, the destination number of the communication is read from the communication management data storage unit 13 and is compared with the data stored in the transmitter side-information storage unit 5 (S601 through S607).
Here, control codes such as a pause code which have no direct relationship with the telephone numbers, when found, are skipped, and the next digit is considered in the comparison. When the controller unit 1 finds the first mismatching digit, on determining that the destination number is not the same, the destination number which is stored in the communication management storage unit 13 is sent to the dialing unit 9 (S611) which in turn issues a command corresponding to the received data to the line controller unit 8, and a signal corresponding to the received command is output to line 2 from the line controller unit 8. In cases where the result of the comparison shows that both numbers completely match, the controller unit 1 waits until line 1 is freed, without carrying out the communication (S608 through S609).
In the flow chart of Figure 7, the information on the other end connected over line 1 which has been initiated by the other end is received from the other end and stored in the transmitter-side information storage unit 5 via the receiver unit 6. Here, the data on the dialing information received from the personal computer is stored in the input-number storage unit 2 via the personal computer I/F unit 4. The controller unit 1 compares the data with the data stored in the transmitter-side information storage unit 5 (S701 through S707).
Here, control codes such as a pause code which have no direct relationship with the telephone numbers, when found, are skipped, and the next digit is considered in the comparison. When the controller unit 1 finds the first mismatching digit, on determining that the destination number is not the same, the data stored in the input-number storage unit 2 is sent to the dialing unit (S711 ) which in turn issues a command corresponding to the received data to the line controller unit 8, and a signal corresponding to the received command is output to line 2 from the line controller unit 8. In cases where the result of the comparison shows that the both numbers completely match, the controller unit 1 erases the data stored in the input-number storage unit 2, without sending it to the dialing unit 9, and sends a signal indicating that the line is busy to the personal computer via the personal computer I/F unit 4 (S708 through S709).
According to the invention, the subscriber number of the other end connected on a first line is compared with the subscriber number which the apparatus is going to dial on a second line, and when the numbers are found to be the same, the result of the comparison is notified to the operator, and the dialing is not performed or is delayed until the already established connection is disconnected, thus improving the usability of the apparatus.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and the range of equivalency of the claims are therefore intended to be embraced therein.
The objects to be considered in the comparison are only the digits of the telephone numbers, and do not include a pause code and other control codes.
6) In cases where the apparatus includes the capability of operating as a data fax modem under control of a personal computer, and another end-initiated connection has been established, when dialing is requested by the personal computer, the information on the other end sent from the other end (i.e.
the telephone number of the other end) is compared with the number to be dialed which has been received from the personal computer (S701 through S707). If both numbers match, no dialing operation is performed, a result code indicating that the line is busy is sent to the personal computer, and the operation is terminated (S708 and S709).
When the first mismatching digit is found, the data is transferred to the dial unit (S710 and S711).
The objects to be considered in the comparison are only the digits of the telephone numbers, and do not include a pause code and other control codes.

unit, 5 is a transmitter-side information storage unit, 6 indicates a receiver unit, 7 is a dial-information storage unit, 8 is a line controller unit, 9 is a dialing unit, 10, 11 and 12 are a display unit, buzz unit and voice-processing unit, respectively and 13 is a communication-management-data storage unit.
The control operation illustrated in Figure 1 will now be described again with reference to a flow chart related to the drawing.
In the flow chart of Figure 2, the subscriber number of the receiving end connected over line 1 is stored in the dial information storage unit 7 of the apparatus. Here, the number input by the operator with the operator unit 3 is stored in the input-number storage unit 2 on a digit-by-digit basis. The controller unit 1 compares the two numbers on a digit-by-digit basis starting with the first digits (S201 through S207).
Here, control codes such as a pause code which have no direct relationship with the telephone numbers, when found, are skipped, and the next digit is considered in the comparison. When the controller unit 1 finds the first mismatching digit, on determining that the destination number is not the same, the data stored in the input-number storage unit is sent to the dialing unit 9 (S212) which in turn issues a command matching the received data to the line controller unit 8, and a signal matching the received command is output to line 2 from the line controller unit 8. Here, the comparison for the number input by the operator is terminated. In cases where the result of the comparison shows that the two numbers completely match, the controller unit 1 erases the data stored in the input-number storage unit 2, without sending it to the dialing unit 9, and notifies the display unit 10, the buzz unit 11 and the voice-processing unit 12 that the apparatus has already been connected to the receiving end, and the respective units perform their own processing depending on the notification (S208 through S210).
