Description

The present invention relates to a facsimile receiver Device capable of receiving the received image information compression to record them.

In the case of a facsimile receiving apparatus using normal size recording papers (such as A4 size, letter size, legal size and B4 size), the following two methods are commonly used when the length L1 is one side received information speaks, is greater than the length K1 of a recording paper K, as shown in Fig. 9, wherein the length K1 is defined as a recordable length. That is, in the case where the length L1 of the image information L is not larger than a threshold value C, the image information L is compressed and printed out on a sheet of paper K as shown in Fig. 9 (a). In this case, the reduction ratio α is defined as a value obtained when the length K1 of the recording paper K is divided by the length L1 of image information L received, that is, the reduction ratio α can be given by the equation α = K1 / L1 can be expressed.

In the case that the length L1 of the image information L exceeds the threshold value C, the image information L is not compressed but divided into a plurality of pages as shown in Fig. 9 (b) so as to be printed out on recording paper K. will. As a result of the foregoing, the excessive compression of image data can be avoided so that the image information can be clearly resolved.

If the characters on a document are from a broadcaster are sent are very small, for example if one Is sent image that is longer than the length K1 of the Recording paper K, which is loaded on the receiving side the image is compressed so that it is open is drawn. Even if the reduction ratio in this If it is not so large, the small characters are further ver diminishes. It is therefore difficult to resolve the small characters sen.

To solve the aforementioned problems, it is necessary take the following measures:

The recipient asks the sender to enlarge the document and send it like this. As an alternative, the recipient asks the Sender to send the document on condition that the automatic facsimile size reduction function nden device is turned off. Thus the operation complicated, the communication costs are increased and moreover, recording paper is wasted.

With the present invention it is achieved that previously to solve the problems mentioned. It is a task of the present invention, a facsimile receiving device create, which is characterized in that when automa table-reduced image information is received, it under the Reduction condition is recorded; and after that she can open up be drawn without being reduced.

To solve the aforementioned problems, the present Invention an image information receiving device available which a receiver device for receiving of image information; a storage device for storing the image information; a detection device for the Received length to capture the length of one side of the Image information corresponds; a recording device for Recording the image information on a recording paper; a recording length detector paper for detecting the length of a recording paper;  a computing device for the reduction ratio to Calculate a reduction ratio of the image information by comparing the length of the recording paper with that the image information; and a reducing device for reducing image information about the reduction ratio, whereby the image information is reduced and recorded, if it is longer than the length of the recording paper, and then the image information in the storage device is saved to the image information afterwards on a Record recording paper without being reduced.

In Fig. 1, the image information L (shown in Fig. 2) received by a receiver device 1 is stored in a memory device 2 . The length L1, which corresponds to one side of this image information L, is detected by a detection device 3 for the received length. In this embodiment, the length L1 (= number of lines / resolution) is made up of the number of lines corresponding to one page and the resolution written in a file control table (shown in Fig. 4) created when received, calculated. In the case in which the length L1 lies between the threshold values A and B (A <L1 C), the length L1 is fed to a computing device 6 for the reduction ratio.

On the other hand, normal size papers representing recording papers K are placed in a recording device 4 , and the length K1 of these recording papers K is detected by a recording device 5 for the length of the recording papers, and the detected length is a calculator 6 for the reduction ratio fed. If the length K1 of the recording papers K is divided by the length L1 of the received image information L in this computing device 6 for the reduction ratio, the reduction ratio α (= K1 / L1) is calculated.

Then, the image information L in the storage device 2 is reduced by a reducing device 7 in accordance with the reduction ratio α, and the reduced picture information is supplied to the recording device 4 and printed out on a sheet of normal size paper. In the case where the length L1 of the received image information L exceeds the threshold value B (B <L1 C), the image information L is stored in the storage device 2 even if the reduction printing has ended, so that the one stored in the storage device 2 Image information L can be fed directly to the recording device 4 under the supervision of an operator, in the case when it is difficult to resolve the image information after the reduction of the image. In this case, the image information L is not reduced, so that fine characters can be read clearly by the operator.

In the event that the length L1 of the received image information L is less than the threshold A, the image will not reduced, but printed out as it is. In the event that the length L1 exceeds the threshold C, the picture becomes not reduced, but divided into several pages and out printed.

In the following, the invention will only be used as an example of the accompanying drawings. It is

An example will be made with reference to the accompanying drawings the facsimile receiving device of the present invention explained in detail as follows.

Fig. 1 is a functional block diagram of the facsimile receiving apparatus according to the present invention. In the drawing, reference numeral 1 is a Receiver device. The receiver device 1 is connected to a communication line and receives image information that has been sent by a transmitter. Reference numeral 2 is a storage device that stores received image information. Reference numeral 3 is a detected length detection device which detects the length of a page of image information stored in the storage device 2 . Reference numeral 4 is a recording device which prints the image information stored in the storage device 2 on a recording paper of normal size. Recording papers of different sizes can be inserted into the recording device 4 .

Reference numeral 5 is a recording paper length detecting device which detects the length of recording papers provided in the recording device 4 . Reference numeral 6 is a reduction ratio calculator that calculates the reduction ratio α to reduce the length of the image information in the case where the length of the received image information is in a predetermined range, as will be described later. Reference numeral 7 is a reduction device that reduces the image information in the storage device 2 in accordance with the reduction ratio α calculated by the calculation device 6 for the reduction ratio. The reduced image information is supplied to the recording device 4 and recorded on a normal size recording paper.

With reference to Fig. 2, a reference will be explained, which is to be used when received image information is printed out. As shown in Fig. 2 (a), the length L1 of received image information L is compared with three threshold values A, B and C. Threshold A is defined as a value at which the length L1 of received image information L is the same as the length K1 of the recording paper K, so that the threshold A discriminates whether or not image information L is reduced. Threshold B is defined as a value by which it is discriminated whether or not image information L is stored in the storage device 2 after a reduction printing operation has been completed. The threshold value C is defined as a value by which it is distinguished whether image information L is reduced or not. In this case, if image information L is not reduced, it is divided into several pages and thus printed.

As shown in Fig. 2 (b), in the case where the length L1 of the received image information L is not greater than A (L1 A), the image information L is not reduced, but is printed out on a recording paper K and is made out the memory device 2 deleted. In the case where the length L1 of the image information L exceeds the threshold value A and is not greater than the threshold value B (A <L1 B), the image information L is reduced with the reduction ratio α and printed out. Then the image information L is deleted from the storage device 2 .

In the case in which the length L1 of the image information L exceeds the threshold value B and is not greater than the threshold value C (L1 C), the image information L is reduced by the reduction ratio α and printed out. The image information L is retained even afterwards in the memory device 2 . In the case where the length L1 of the image information L exceeds the threshold value C (C <L1), the image information L is not reduced but divided into several pages, so that the divided information on a plurality of pages of recording paper K is printed out. In this case, the image information L is deleted from the storage device 2 after printing.

Fig. 3 shows the structure of this facsimile-received device. In the drawing, reference numeral 11 is a CPU (central processing unit) for controlling the facsimile device, reference numeral 12 is a ROM in which various control programs such as a transmission program are stored, and reference numeral 13 is a RAM in which image information such as that to be transferred is saved. The image information read from an image reading area 14 is stored in the RAM 13 via an interface 15 . A short time later or immediately thereafter, the information is supplied to a modem, which acts as a transmission device, and also to a network control circuit (NCU) 16 . Image information that is input via a communication line is stored in a file memory 23 by this modem and the NCU 16 . This information is decoded and supplied to the page memory 24 , or the information is supplied to the page memory 24 as it is. Then, the information is fed from the page memory 24 into a recording area 18 which functions as a printer so that the content of the information can be printed.

The telephone number of the transmitter is displayed when it is given to a display area 20 via an interface 19 . An operating area 21 is provided with a plurality of keys (not shown). When these buttons are pressed, the content of the information is input to the CPU 11 through an interface 22 . This facsimile receiving device includes the aforementioned detection device 3 for the received length, the detection device 5 for the length of the recording paper, the computing device 6 for the reduction ratio and the reduction device 7 .

When image information L is received by this facsimile receiving device, the received information is stored in the file memory 23 and a reception file is created for each page of image file communication. This image information L is decoded in order to detect the number of faulty lines and the length L corresponding to one page of information. When a page of the image information L has been received, the file control table shown in Fig. 4 is created. Various information, such as the name of the recipient file, reception time, coding system, resolution, number of lines on this page, address at which a reception file is accessible, file size and the flag for the printing process are written into the file control table. First, "1" indicating that a printing operation has not been performed is entered in the column of the printing process flag. In the case of and after the second page, a file control table is created in the same manner as described above.

FIGS. 5 and 6 are flowcharts showing the procedure of the print processing of image information 30 L which is stored in the reception file. For example, when the "Print" button is pressed for the reprint operation or when each page image is received, the file control table (shown in Fig. 4) is referred to and it is decided whether or not a reception file exists (step 31 ). If it is decided that a reception file does not exist, the printout processing 30 is completed. If it is decided that the reception file exists, a decision is made as to whether the reception file has been printed or not, that is, whether the flag for the printing process is "1" or not (step 32 ).

In the event that it is decided that the flag for the printing process is "1", the length L1 of image information L received is calculated from the resolution and the number of lines (step 33 ). For example, in the case where the resolution is 3.85 lines / mm and the number of lines is 770 , the length L of this page is calculated as follows: L1 = 770 / 3.85 = 200 (mm). Next, the length L1 and the threshold A are compared with each other (step 34 ). In the event that the length L1 exceeds the threshold value A, this length L1 is compared with the threshold value C (step 35 ).

In the case where it has been decided that the length L1 does not exceed the threshold value C, the image information L is read from the file memory 23 as shown in Fig. 6 (step 36 ) and then the image information is decoded (step 37 ). The decoded image information L is successively reduced by the reduction ratio α (step 38 ), and the reduced image information is written into the page memory 34 (step 39 ). Next, it is decided whether or not it is a page end (step 40 ). In the case that it is not a page end, the next line is read from the file memory 23 in step 36 , and the decoding processing and the writing to the page memory are carried out in the same manner as previously described.

In the case that it has been decided in step 40 that it is a page end, the image information in the page memory 24 is printed out successively (step 41 ). Next, the received image information L1 is compared with the threshold value B (step 42 ). In the case that the length L1 of the image information has exceeded the threshold value B, the flag for the printing process of the next file control table is changed to "2" (step 43 ). In this way, the printout processing is ended. In the case where it has been decided in step 42 that the length L1 of the image information is not larger than the threshold value B, its reception file is deleted (step 44 ). In this way, the expression processing 30 is ended. In this case, the degree of reduction is small, so it is decided that reprinting to create a printed image of the original size is not necessary. The receive file is therefore deleted.

In the case where it has been decided in the aforementioned step 32 that the reception file is printed, that is, in the case that it is decided that the flag for the printing process is not "1", it is next decided to whether or not reprinting is required, that is, it is decided whether or not the flag for the printing process is "3" (step 45 ). In the case that it is decided that the reprint is not required, that is, in the case that it is decided that the flag for the printing process is "2", this printout processing 30 is completed.

Image information L is read out from the file memory 23 in the following cases (step 46 ): In the event that it has been decided in step 45 that the reprinting is required; in the case where it has been decided in step 34 that the length L1 of the image information is not greater than the threshold value A; and in case it has been decided that the length L1 of the image information exceeds the threshold value C. Next, this picture information is decoded (step 47 ), and then it is written into the page memory 24 (step 48 ). Next, it is decided whether or not it is a page end (step 49 ). In the event that it is not a page end, a decision is made as to whether the page memory 24 is in a filled state or not (step 50 ).

In the event that it has been determined that the page memory is not fully loaded, the next line is read from the file memory 23 in step 46 , the information is decoded and written to the page memory in the same manner as previously described. In the event that it has been decided in step 50 that the page memory 24 is fully loaded, the image information in the page memory 24 is printed out, and then the image information L1 is read out from the page memory 23 in step 46 , and the same processing as is described above.

In the event that it is decided in step 49 that it is a page end, the image information is printed out in the page memory 24 and then a reception file which makes the image information accessible is deleted in step 44 . In this way, this expression processing 30 is completed. After all of the aforementioned print processing 30 is completed, only the merge reception file for printing process "2" and its file information remain in the file memory 23 and the file control table.

Even after being automatically reduced and printed out, the reception file remaining in the file memory 23 can be printed out according to the instruction given by an operator without being reduced. FIG. 7 is a flowchart showing a procedure of the reprint processing 60 . For example, if the operator presses the "reprint" button, a decision is made as to whether the reception file exists or not (step 61 ). In the event that the receive file does not exist, it is indicated that there is no file (step 62 ). In this way, re-expression processing 60 is completed.

In the case where it is decided in step 61 that the reception file exists, the program waits until the reception file name is entered (step 63 ). Successively, the file control table is referred to and a decision is made as to whether the input file name exists or not (step 64 ). In the event that the input file name exists, the flag for the printing process in the file control table is changed to "3" (step 65 ). The image information L is successively printed out isometrically in the reception file (step 66 ). In this way, reprint processing 60 is completed. In the event that it is decided in step 64 that there is no entered file name, it is indicated that the information has been entered incorrectly (step 67 ). In this way, this reprint processing 60 is completed.

Fig. 8 is a flowchart showing a procedure of the processing 70 for displaying the remaining capacity of the file memory 23 . First, it is decided whether the remaining capacity of the file memory 23 is not larger than a predetermined capacity or that it is, that is, in this example, it is decided whether the remaining capacity of the file memory 23 is not larger than 64 KB (byte) or not it is (step 71 ). In the event that it has been decided that the remaining capacity is not less than 64 KB, it is indicated that the file memory 23 has an open position (step 72 ). In this way, this processing 70 for displaying the remaining capacity is completed.

In the event that it has been decided in step 71 that the remaining capacity of the file memory 23 is less than 64 KB, the file control table is referred to and it is decided whether or not there is a receive file whose flag for the printing process " 2 "(step 73 ). In the event that it is decided that there is no receive file, it is indicated that the file memory 23 is in a full state (step 24 ). In this way, this processing 70 for displaying the remaining capacity is completed.

In the event that it is decided in step 73 that there is a reception file whose flag for the printing process is "2", the oldest file is deleted from the reception file (step 75 ). Next, in step 71 , it is decided whether or not the remaining capacity of the file memory 23 is less than 64 KB, and then the same processing as described above is performed. As a result of the foregoing, the file, once reduced and printed, is left after all. Therefore, the file memory 23 can be prevented from becoming full.

As explained above, the present invention is intended to be a Faksi Provide mile-receiving device once the image information is reduced and that on a recording paper if it is longer than the length of the recording drawing paper, and then the image information again can be recorded on a recording paper without it is reduced.

According to the invention, even if image information becomes longer is received as a recording paper and even if the Characters in the image information are very fine and received image information is automatically reduced and printed out the image information originally received in the memory chereinrichtung saved and printed without them is reduced. Thus, a printed area that redu has been adorned so that it is difficult to read on his Original size to be restored so it is checked can be.  

According to the present invention, it is not necessary to have one To ask the sender to submit the document again on condition send that the document is enlarged and it is also for the recipient does not need a document under the conditions to receive that the automatic reduction function of the Facsimile receiving device is turned off. Demge According to this, the increase in communication costs can be prevented and recording papers are not wasted.
