Commands such as requests and replies exchanged between the PUs 104 or data flows will be mainly described, and commands such as unimportant requests and replies will be omitted. In facsimile transmission, a facsimile apparatus that performs a call is called a calling side, and a facsimile apparatus that is called in response to this is called a called side. Further, in facsimile transmission, a facsimile apparatus that transmits image data is called a transmitting side, and a facsimile apparatus that receives image data is
Called the receiving side. Therefore, in normal facsimile transmission, the calling facsimile machine becomes the transmitting side for transmitting image data, and the called facsimile machine becomes
The receiving side receives image data. In the polling transmission, the calling facsimile apparatus becomes the receiving side for receiving the image data, and the called facsimile apparatus becomes the transmitting side for transmitting the image data.

(3-1) Operation Sequence in Facsimile Transmission FIG. 4 is a diagram showing an operation sequence in facsimile transmission. In facsimile transmission, image data read by the reading device IR is temporarily written into the image memory 125,
After being subjected to compression processing and stored in the code memory 126, the data is converted by the facsimile conversion unit 41 and transmitted by facsimile.

Specifically, in the facsimile mode, when the start key 96 is pressed, the CPU 101
Sends a facsimile transmission request to the CPU 104. In response, the CPU 104 issues a scan request to the CPU 102. Thereby, the CPU 102
Starts scanning and, when the image reaches the image area of the document, performs image processing. The processed image data is output to the memory unit 30 and stored in the image memory 125. Thereafter, the CPU 104 compresses (encodes) the image data in the image memory 125, and stores the compressed image data (code data) in the code memory 126.

When the reading of the document image by scanning is completed, a response to the end of scanning is issued from the CPU 102 to the CPU 104, and a response to the end of facsimile transmission is issued from the CPU 104 to the CPU 101. Code memory 1
When all the compressed image data to be transmitted is stored in the CPU 26, the CPU 104 controls the G3 unit 42 to instruct the line connection, and in response to the call, makes a call to the called receiver side to perform the line connection and perform the line connection. Receive a response.

Next, the CPU 104 reads out the compressed image data and outputs it to the facsimile conversion unit 41. After performing the image data conversion, the G3 unit 42 modulates the data by a modem and receives the data via the telephone line (PSTN). Send to When image data transmission is completed,
The CPU 104 sends a line disconnection request to the called receiver to perform a line disconnection process, clears the image memory 125, and ends the operation.

When printing a transmission report after facsimile transmission is completed, or when printing a transmission error report due to an error during transmission, the CP
A print request is issued from U104 to CP103.
As a result, the CPU 104 creates image data for printing the report on the image memory 125, outputs the image data to the print processing unit 40, and the print processing unit 40 starts printing. When the report print is completed, the CPU 103 sends a print end response to the CPU 104, clears the memory, and ends the operation.

Here, the transmission report is a transmission record automatically printed after a predetermined number of facsimile transmissions or at a predetermined time interval (for example, every day at 12:00). For example, a report listing the number of transmitted documents, date and time of transmission, and destinations is printed. In addition, a transmission error report is generated when an error such as a communication error occurs during facsimile transmission and facsimile transmission is not performed normally.
This is a report that is printed to notify the operator of this fact. The error report includes "NG" indicating that an error has occurred, together with the transmission destination and the transmission date and time.
Is written.

(3-2) Operation Sequence in Facsimile Reception FIG. 5 is a diagram showing an operation sequence in facsimile reception. In the facsimile reception, the received image data is converted by the facsimile conversion unit 41, stored in the code memory 126, subjected to decompression processing, written into the image memory 125, output to the printer PR, and printed. Is done.

More specifically, in the facsimile mode, when an incoming call request is made to the CPU 104 from the calling transmission side, the CPU 104 makes a line connection. Next, CPU1
Numeral 04 sets various parameters for facsimile reception indicating an encoding method, a reception magnification, the number of pixels of one line of a received image, the number of pixels of one line of an input image, the maximum allowable number of lines of line error, and the like.

When the preparation for reception in the code memory 126 is completed, the image data transmitted from the calling transmission side is demodulated by the modem in the G3 unit 42 and the facsimile conversion unit 4
After the data conversion in step 1, the data is stored in the code memory 126.
When the reception of the image data is completed, the CPU 104 performs a line disconnection process and issues a print request to the CPU 103.
When the CPU 104 issues a print request, the image data is then decompressed, the image data is written to the image memory 125, and the read image data is stored in the printer PR.
And the print is performed.

When the printing is completed, the CPU 103 sends a printing completion response to the CPU 104. In response, the CPU 104 clears the image memory 125 and ends the operation. When a reception report is output after facsimile reception is completed, or when a reception error report is output due to an error during reception, a print request is issued from the CPU 104 to the CPU 103. Thus, the CPU 104 creates image data for printing the report on the image memory 125, outputs the image data to the print processing unit 40, and outputs the image data to the print processing unit 4.
0 starts printing. When the printing of the report is completed, the CPU 103 sends a print end response to the CPU 104, clears the image memory 125, and ends the operation.

Here, the reception report is a reception record that is automatically printed after a plurality of predetermined times of facsimile reception or at predetermined time intervals (for example, every day at 12:00). For example, a report listing the number of received documents and the date and time of reception is printed. Also, the reception error report is
When an error such as a communication error occurs during facsimile reception and facsimile reception is not performed normally, this is a report printed to notify the operator of the fact. At the same time, a character "NG" indicating that an error has occurred is described.

The operation sequence of the facsimile reception described above has been described for the operation in the facsimile mode. However, when the facsimile reception is performed in the copy mode, the received image is transmitted in the same manner as the operation in the facsimile mode. Although the data is stored in the code memory 126, the printing operation is not immediately performed, and the apparatus stands by until the facsimile mode is set. After the facsimile mode is set, the CPU 103 issues a print request to the CPU 103 and executes printing.

(3-3) Operation Sequence in Polling Transmission FIG. 6 is a diagram showing an operation sequence in polling transmission. In the polling transmission, the image data of the document read by the reader IR is once written in the image memory 125, subjected to compression processing, stored in the code memory 126, and registered for the polling transmission. Since a plurality of polling transmissions can be registered, they are managed by a management table created on the RAM 124. When image data to be transmitted is designated from a plurality of registered image data, the designated image data is read from the code memory 126, converted by the facsimile converter 41, and transmitted by facsimile.

Specifically, when an operation for registering polling transmission is performed by operating the operation panel OP, the CPU 1
From 01, a polling registration request is issued to the CPU 104. In response, the CPU 104 issues a scan request to the CPU 102. Thereby, the CPU 10
2. When scanning starts and reaches the image area of the original,
Image processing is performed, and the processed image data is output to the memory unit 30 and stored in the image memory 125.
Thereafter, the CPU 104 compresses the image data in the image memory 125, stores the compressed image data in the code memory 126, and updates a management table created on the RAM 124. Up to this point is the registration of polling transmission, and when the registration of polling transmission is done,
Wait for an incoming call request from the call receiving side. When an incoming call request is made from the call receiving side to the CPU 104, the CPU 104 makes a line connection. Next, the CPU 104 receives the polling designation number transmitted from the call receiving side, searches the management table of the RAM 124 for the received polling designation number, and, based on this, the image designated by the code memory 126. Read data. Further, the CPU 104 outputs the read image data to the facsimile conversion unit 41, performs image data conversion there, modulates the data by a modem in the G3 unit 42, and transmits the modulated data to the call receiving side through the telephone line (PSTN). When the transmission of the image data is completed, the CPU 104 sends a line disconnection request to the call receiving side to perform a line disconnection process, clears the image memory 125, and ends the operation.

(3-4) Operation Sequence in Copy Operation FIG. 7 is a diagram showing an operation sequence in the copy operation. In the copy operation, image data read by the reading device IR is temporarily written into the image memory 125, and is output from the image memory 125 to the print processing unit 40 and printed.

Specifically, in the copy mode, when the start key 96 is pressed, the CPU 101
A copy operation request is issued to U104. In response, the CPU 104 issues a scan request to the CPU 102. Thus, when the CPU 102 starts scanning and reaches the image area of the document, it performs image processing, and the processed image data is output to the memory unit 30 and stored in the image memory 125.

When the reading of the original image by the scanning is completed, a response to the completion of the scanning is issued from the CPU 102 to the CPU 104.
A print request is issued to. Thereby, the CPU 104
However, the image data to be copied is read from the image memory 125, and the image data is output to the print processing unit 40, and the print processing unit 40 starts printing. When the printing is completed, the CPU 103 sends a printing end response to the CPU 104, clears the image memory 125, and ends the operation.

(3-5) Operation Sequence in Confirmation Print FIG. 8 is a diagram showing an operation sequence in confirmation print. Here, the confirmation print means that the image data for which the polling transmission has been registered is read out from the code memory 126 so that the type of the document for which the polling transmission has been registered can be confirmed. To print.

More specifically, when the start key 96 is pressed in the confirmation print mode, the CPU 101
Sends a confirmation print request to the CPU 104.
In response to this, the CPU 104 searches the management table of the RAM 124 for the registration number of the polling transmission specified on the operation panel OP, and, based on this, the image registered in the registration number specified by the code memory 126. The data is read and decompressed, a predetermined pattern is read from the ROM 114, and the decompressed image data and the predetermined pattern are combined on the image memory 125. Next, the synthesized image data is output to the print processing unit 40, and the print processing unit 40 starts printing. When printing is completed, the CPU 103 sends a print end response to the CPU 104, and in response, the CPU 104
Then, a confirmation print end response is output, and the image memory 125 is cleared to end the operation.

The reason why the predetermined pattern is combined with the image data in the confirmation print is to identify the output image of the copy operation and the output image of the confirmation print.

Here, the mode change timer is a timer that starts timing when a key input is made from the operation panel OP or when the copy operation is completed. Becomes the facsimile mode. Here, the time until the mode change timer expires is, for example, 10 minutes. Therefore, when 10 minutes have passed since the last key input or the end of the last copy operation, the digital copying machine enters the facsimile mode. The mode change flag is a flag that is set to "1" when the mode change timer times out, and the facsimile mode is set by determining the state of the mode change flag. Next, in # 7, key input processing corresponding to the type of key input determined in # 3 is executed. When the time-up of the mode change timer is detected in # 8, the mode change flag is set to "1" in # 9, and in # 10, the process of # 2 is executed again after waiting for the end of the internal timer. .

(4-2) Control Procedure of CPU 104 FIG. 22 is a main flowchart showing a control procedure executed by the CPU 104. Referring to FIG.
In digital copiers, after the power of the device is turned on, the ROM
Initialization is performed based on the initial setting conditions registered in 114 (# 101). After that, the apparatus is in a state of waiting for a command from the CPU 101 that controls the operation panel OP. C
If a command is input from PU 101 ($ 10
2) Detect command contents and execute processing corresponding to the command (# 103- # 107). When a facsimile transmission request command is input, a subroutine for facsimile transmission control is executed (# 104). The specific processing in the facsimile transmission control subroutine is described in (3-
As described in the section 1), a scan request is output to the CPU 102, the image data read by the scan request is received, the image data is compressed, and the transmission set in the previous step # 41 is performed. Call is made first and facsimile transmission is performed. When a copy request command is input, a copy processing control subroutine is executed. In the copy processing control subroutine, as described in the above section (3-4), a scan request is output to the CPU 102, image data read by this scan request is received, and output to the printer PR. Then, the read image data is printed. In addition, in the copy processing control subroutine, the mode change timer is reset to "0" before the start of the copy operation, and after the end of the copy operation, the mode change timer is started to start measuring a predetermined time. When a polling registration request command is input, a subroutine for polling registration control is executed (# 106). This process will be described later in detail with reference to FIG. 23.
This is the same as the registration of the polling transmission described in the section -3). When the confirmation print request command is input, a subroutine for confirmation print control is executed (# 107). This process will be described later in detail with reference to FIGS. 29 and 32, but the outline is as described in the above section (3-5).

Next, a reception control subroutine (# 108) for printing processing of the image data received by facsimile and setting processing of the facsimile mode by time-up of the mode change timer is executed. This processing will be described later in detail with reference to FIG.

If the G3 unit 42 receives the designated polling number from the telephone line (PSTN), the subroutine of polling transmission control (# 109) is executed.
The processing here is as described in the section (3-3) described above. That is, an incoming call request from the calling receiving side is
When the number is set to 4, the CPU 104 makes a line connection. Next, the CPU 104 receives the polling designation number transmitted from the call receiving side, searches the management table of the RAM 124 for the received polling designation number, and, based on this, the image designated by the code memory 126. Read data. Further, the CPU 104 converts the read image data into
The data is output to the facsimile converter 41, where the image data is converted, and then modulated by the modem in the G3 unit 42 and transmitted to the call receiving side through the telephone line (PSTN).

When a predetermined number of facsimile transmissions have been performed, a predetermined number of facsimile receptions have been performed, or an error has occurred in facsimile transmission / reception, a report process (# 110) is performed. This processing will be described later in detail with reference to FIG.

FIG. 23 shows a polling registration control subroutine indicated by # 106 in FIG. First, $ 111
Then, a scan request is output to the CPU 102. As a result, the document is scanned, and the image data of the scanned document is stored in the image memory 125. Next, in step # 112, the image data stored in the image memory 125 is read out and compression processing is performed. The compressed image data is written into the code memory 126 in the processes of # 113 to # 118 described later. Here, the code memory 12
As described above, since a plurality of polling transmissions can be registered in the memory 6, the image data on the code memory 126 is managed by a management table on the RAM 124.

FIG. 24 is a diagram schematically showing the state of the management table, and FIG. 25 is a diagram showing the state of the image data registered in the code memory 126. Code memory 126
Are divided into memory areas in units of 32 Kbytes, as shown in FIG. 25, and area numbers 01, 02, 03,... Are sequentially assigned to the divided areas. The unit is managed by the management table. When polling transmission is registered in each area,
The image data of the read document is stored in a compressed state. In the management table, page information, previous link information, rear link information, registration number information, and additional information, which are information indicating what image data is stored in each area of the code memory 126, are provided for each area. It is memorized. The page information indicates on which page of the document the image data is stored. The pre-connection information and the post-connection information are information indicating a connection state of each area when image data registered at a certain registration number is stored over a plurality of areas.
If “00” is stored in the preceding link information, it indicates that the data is the first image data of the registered image data,
If a value other than “00” is stored, it indicates that image data subsequent to the image data stored in the area indicated by the stored previous connection information is stored. When “FF” is stored as post-link information, it indicates that the last part of the registered image data is stored. When anything other than “FF” is stored, ,
This indicates that the subsequent image data is stored in the area indicated by the connection information after being stored. The polling number information indicates the registration number described above. “00” is assigned to an area where image data other than the registration number is stored.

Here, the case shown in FIG. 24 will be specifically described. In the registration number 01, image data of a document of a total of one page is stored in areas 01 and 02. The first half is stored in area 01, and subsequently, the second half is stored in area 02. Further, in registration number 02, image data of a document of a total of two pages is registered. The image data of the first page is stored in areas 03 and 04, and the image data of the second page is stored in areas 05 and 06. Is stored in Also, area 0
3, 04, 05, and 06, the image data following the area 03 is stored in the order of the areas 04, 05, and 06, and the last part of the image data in which the area 06 is registered as the registration number 02. It is.

Therefore, when the polling designation number is received from the call receiving side in the processing polling transmission control at the above step # 109, the registration number on the management table is searched,
The image data stored in the area provided with the registration number corresponding to the received polling designation number is sequentially read out according to the pre-connection information and the post-connection information, and facsimile transmission is performed. For example, if the received polling designation number is "0
If “2”, “0” is added to the registration number information in the management table.
Image data is sequentially read out from the areas 03, 04, 05, and 06 marked with 2 "in accordance with the pre-link information and the post-link information, and facsimile transmission is performed.

Referring again to FIG. 23, the above-described ♯
That the new registration mode has been set in the process of 49,
If it is determined in # 113 (YES in # 113), the image data compressed in # 112 is written into the free area of the code memory 126 (# 114). Further, the registration number of the area where the image data is written on the management table includes $ 5 described above.
The management table is updated by attaching the registration number set in the processing of step 6 and attaching the preceding and succeeding link information as appropriate. As a result, the image data of the document is newly registered at the registration number designated on the registration number designation screen, and the new registration of the polling transmission is completed.

If it is determined at # 115 that the overwrite change mode has been set in the process of # 52 described above (YES at # 115), the registration is already performed with the registration number set at # 56 above. The erased image data on the code memory 126 is erased (# 116), and the erased area is # 112
The management table is updated by writing the image data compressed in step (# 117).

Here, # 116 and # 117 will be specifically described. There are three types of relationship between the amount of registered existing image data to be erased in # 116 and the amount of new image data to be newly written in # 117.

First, when the amount of existing image data is equal to the amount of new image data, in this case, the image data specified by the registration number is erased and new image data is written in the erased area. good.

Second, the amount of new image data is smaller than the amount of existing image data. In this case, the image data is managed in the management table on the assumption that the image data is not stored in the area of the difference between the existing image data and the new image data. For example, as shown in FIG. 24, when two pages of image data are already stored in areas 03 to 06 as registration number 02, and one page of image data is newly registered instead of this image data. 26, new image data is registered in the areas 03 and 04, and therefore, as shown in FIG.
The page information, the pre-connection information, and the post-connection information of No. 4 are rewritten. Also, in order to manage the image data as not stored in the areas 05 and 06, the front link information and the rear link information are set to “FF” and the registration number information is set to “00”.

Third, the new image data has a larger amount than the existing image data. In this case, new image data is written in an area from which existing image data has been erased, and excess new image data is written in another free area. For example, as shown in FIG. 24, when registering new image data for two pages in place of image data for one page already registered as registration number 01 in areas 01 and 02, a new image The first page of data is written to areas 01 and 02, and the second page of new image data is written.
The page number is written in areas 09 and 10 which are free areas.
The management table in this case is as shown in FIG. 27, and “09” is added to the post-connection information of the area 02 and the area 09 is added.
Shows that the following image data is stored. Referring to FIG. 23 again, as described above,
Reference numerals 115 to 117 indicate registration of polling transmission in the overwrite change mode. That is, in the registration of the polling transmission in the overwrite change mode, the image data already registered with the registration number designated on the registration number designation screen is replaced with new image data.

Next, it is not the new registration mode (# 113
NO in case of not being in overwrite change mode (# 115
NO), that is, when the addition change mode is set in the previous step # 54, the image data compressed in the step # 112 is written in the free area of the code memory 126, and the above-mentioned # 5 is also used.
The management table is updated so that the written image data is linked to the image data registered with the registration number set in the process 6 (# 118).

In the process in # 118, a process of connecting new image data to already registered image data is performed. For example, as shown in FIG. 24, a case where one page of image data is registered in addition to two pages of image data registered as a registration number 02 will be described. In this case, as shown in FIG. 28, the image data for one additional page has the registration number 0 in the free areas 09 and 10.
2 and the last link information of the area 06 in which the final image data of the registration number 02 is stored is “09”.
And is linked with the newly registered image data of one additional page. By this, when “02” is designated as the polling designation number by the receiving side at the time of polling transmission, the image data of two pages stored in the existing areas 03 to 06 and the additional data stored in the areas 09 and 10 are added. The image data for a total of three pages including the image data for one page is sequentially read out and transmitted by facsimile.

Next, the subroutine for confirmation print control indicated by # 107 in FIG. 22 will be described. FIG. 29 is a flowchart showing a subroutine of the confirmation print control. The CPU 104 issues a confirmation print request to the CPU 101.
Then, the image data registered with the registration number set in the process of # 58 is read out from the code memory 126 and expanded by referring to the management table (#
119). Next, a predetermined pattern is read from the ROM 114 (# 120), and combined with the image read in the process of # 119 on the image memory 125. FIG. 30 is a diagram showing this state. In this case, “X” indicates RO as a predetermined pattern.
A predetermined pattern is registered on the image data registered in M114. The synthesized image data is output to the printer PR and printed at # 122. The confirmation print is a print performed by the operator to confirm the image data for which the polling transmission has been registered, and is printed with a predetermined pattern superimposed thereon so as to be distinguishable from the copy print.

In place of the confirmation print control of FIG. 29, FIG.
It is also possible to adopt the second check print control. In the confirmation print control of FIG. 32, a predetermined pattern is not combined, but is reduced and printed as shown in FIG. 31, so that it can be identified as a copy.

Further, the present invention is not limited to the combination of the predetermined pattern and the reduced copy, but the print color may be changed or printed as a negative image.

Next, reception control indicated by # 108 in FIG. 22 will be described. FIG. 33 is a flowchart showing a subroutine of this reception control. First, it is determined whether or not facsimile transmission has been received in # 123, and if facsimile transmission has been received (YE in # 123)
S), the received image data is stored in the code memory 126 (# 124). Next, it is determined whether or not the current mode is the copy mode (# 125). If the mode is the copy mode (YES in # 125), and the mode change flag is "1" (YES in # 126), At # 127, the mode is switched from the copy mode to the facsimile mode (# 127). That is, as described above, the mode change flag is a flag that is set to “1” after a lapse of a predetermined time from the last key input or after a lapse of a predetermined time from the end of the copy operation. By the above processing, the facsimile mode is automatically set after a lapse of a predetermined time from the last key input or after a lapse of a predetermined time from the end of the copy operation. When in facsimile mode (♯
If the facsimile mode is set in 127 or if NO is determined in # 125), the previous # 124
It is determined whether or not the received image data is stored in the code memory 126 in the process (# 128), and if there is image data (YES at # 128), the image data is expanded and output to the printer PR (# 128). # 129). Also, $ 126
If it is determined that the mode change flag is not "1" (NO in # 126), even if the image data is received by facsimile, the print processing is prohibited (# 13).
0).

As described above, in the reception control shown in FIG. 33, the facsimile mode is automatically set after a lapse of a predetermined time from the last key input or after a lapse of a predetermined time from the end of the copy operation. If the received image data is in the code memory 126 when the mode is set, the printing of this image data is automatically started. Conversely, if the predetermined time has not elapsed, the received image data is stored in the code memory 126, but the printing operation is not performed, and the printing is executed after the predetermined time has elapsed.

Next, the report processing indicated by # 110 in FIG. 22 will be described. FIG. 34 is a flowchart showing a subroutine of this report processing. First, $ 1
At 30, it is determined whether it is time to output a report. Here, the report refers to the transmission report, the transmission error report, the reception report, and the reception error report described above. The transmission report and the reception report are automatically printed after a plurality of predetermined times of facsimile transmission or reception or at predetermined time intervals (for example, every day at 12:00). The transmission error report and the reception error report are transmitted during facsimile transmission and reception. Is automatically printed when an error such as a communication error occurs. Therefore, at $ 130, whether a predetermined number of times of facsimile transmission / reception has been performed or whether a predetermined time (12:00) has been reached,
Alternatively, it is determined whether a communication error has occurred in facsimile transmission / reception, and when it is determined that it is time to output the report (YES in # 130), image data of the report to be output is created in image memory 125 (# 13).
1) At the same time, the report flag indicating that the image data of the report to be printed exists in the image memory 125 is set to "1". Next, it is determined whether or not the current mode is the facsimile mode (# 133). If the mode is the facsimile mode (# 133: YES), the state of the report flag is determined (# 134). Here, when it is determined that the report flag is set to “1” (♯
