In addition to being sent from the other party's facsimile machine via the CU) 6 and modem 7, the data is sent via the interface 8 to a terminal (not shown) that performs processing operations using a character code P.
For example, it is sent from a computer (for example, a computer processor). Further, the image data stored in the image data buffer 5 is
In addition to being image data sent from the other party's facsimile machine via 6 and modem 7, it is also raw image data photoelectrically converted by reading unit 9. Here, it is assumed that raw image data obtained by decoding encoded data such as MR or MH encoded data sent from the other party's facsimile device is stored in the image data buffer 5.

Character code stored in character code buffer 4
t-)' and the image data stored in the image data buffer 5 are for transmission, the modem 7 and the NCU
6 to the other party's facsimile machine, and when it is received, the character call r is converted into image data (binary data corresponding to each image failure) by the character generator 1°, and the character call r is converted into image data (binary data corresponding to each image failure), and 7i! The image data in the IR image data buffer 5 is sent to the recording section 11 as is. The recording unit 11Fi and receiver perform recording operations based on the captured image data.

12Fi indicates a panel section, from which a transmission start command, necessary information such as destination information, and necessary commands can be input, and display is performed using a predetermined display lamp. Incidentally, when the character code for transmission is stored in the character code buffer 4, and the other party's facsimile machine does not have a character call receiving function, the character code is converted into image data by the character generator 10, and this is sent to the modem. 7 and NCU
6.

When the composite facsimile apparatus configured as described above functions as a receiver, the main parts are as shown in FIG.

That is, 101 is a recording order determining means, which constitutes a part of the control section 1, and the NCU 6, which is a receiving section, via the path 2,
-Identification information (N
information indicating whether the original data is a character code or image data) 102 and free space information 103 obtained from the character code buffer 4 are input, and the input identification information 102 indicates reception of image data. sometimes,
When it is decided to take out data to be recorded next (hereinafter referred to as recording data) from the image data buffer 5, and the identification information 102 indicates reception of a character code, the free space of the character code buffer 4 is less than or equal to a predetermined value. Only when the free capacity information 103 indicating . This decision output 104 is given to the recording means 105, and the recording means 105 refers to the decision output 104 every time recording is completed based on the record data for one page of the original, and based on this, the image data ζ file 5 or , read data from any of the character codes 4,
Perform recording operation. Reference numeral 106 denotes a capacity detection means for detecting an area not filled with character codes r in the character code buffer 4 and outputting free capacity information 103.Actually, it is incorporated in the character code buffer 4 as a read/write section. It is assumed that

In the compound facsimile machine configured in this way,
The reception and recording operations will be explained according to the flowchart in FIG.

First, when document reception is started, the NCU 6 determines the character code of the data to be transmitted based on the data obtained from the other party's facsimile machine according to the negotiation procedure (pre-transmission procedure) in the transmission control procedure. or image data is output. This identification information 102
is taken into the recording order determining means 101. Therefore, in step 2 (II in FIG. 3), it is determined whether the code is a character code or not. If YES, the process proceeds to step 202 and initializes necessary registers and the like.

Next, the process advances to step 203, where page register N of the received original is entered.
Set the Kzeguchi.

Further, the process proceeds to step 204, and the recording order determining means 101 receives the free space information 103 and determines whether the character code buffer 4 is full. If NO, it sets 1 to the page register N in step 205. Set, step 20
In step 6, the start address of the -th page is registered in the corresponding register. After this, in step 207, the character code sent from the other party's facsimile machine is
CU6, modem 7,) character code via modem 9)
'Stored to notice 4. As a result, when the reception of the character code P for -page is completed, the other party's facsimile machine sends a signal (for example, EOM) indicating that -page has ended and there is a document to be sent. Therefore, the control unit 1 receives this from the NCU 6 and branches to YES in step 208.

Next, in step 209, the end address of the character code/muffer 4 that stores the character codes r of the original for -pages is stored in the corresponding register xp. Furthermore, in step 210, it is determined whether the communication is to be terminated.

In other words, as long as a signal such as EOMlMPS is sent from the other party's facsimile machine, the communication does not end, but the EOP
When a signal indicating that there are no continuously fed originals is transmitted, the communication ends.

If NO in this step 210, the next step 21
1, it is determined whether the next document to be transmitted is a character code r. This judgment is done in step 20.
1, the decision is made upon receiving the meeting signal in the meeting transmission control procedure. If YES here, the process returns to step 204 again, and the operation of storing the character code in the character code/9 file 74 is performed.

In this way, when the character code buffer 4 is filled with the character food of several pages of the original (this volume means that the character code of one page of the original cannot be stored in the character code buffer 4), In step 204, a branch is made to YES. Since there is no area to store the character code, the control unit 1
In step 212, the WA sends a message to the NCU 6 to inform the other party's facsimile machine to wait for the transmission of the document.
Commands the sending of IT signals. On the other hand, recording order determining means 10
1 is a determination output that instructs the recording means 105 to read the character code from the character code buffer 4 and perform a recording operation, since the character code buffer 4 is full according to the free capacity information 103. 104 is sent. In addition to this, recording means 1
Step 05 refers to the data in the registers used in steps 205, 206, and 209, and performs a recording operation on the character code P (111) for the manuscript with a small number of pages. here,
The character code r is once converted into image data via a character generator 10. During this time, the control unit 1i1
t, in step 214, it is determined whether an area capable of storing the character code of the document on page - is secured, and if YES, in step 215, N'CU
The facsimile machine 6 instructs the other party's facsimile machine to send an OK signal indicating that it is ready for reception. Thereafter, the transmitted character code is stored in the character code/9 file 4 according to the processing in the flowchart from step 205 onwards. Further, when the recording means 105 finishes the recording operation based on the recording data for one page of the document, it waits for the recording order determining means 101 to output an instruction regarding the next recording data.

Further, when the transmitted data includes image data, step 201 or step 21
The process proceeds from step 1 to step 216, where reception processing is performed on the image data. That is, when image data is received, the control unit 1 is notified of this by the N CU 6-15' and stores the image data in the image data buffer 5. On the other hand, the recording order determining means 101 learns from the weaving information 102 that the data is image data, and determines to read the next recording data from the image data buffer 5. The recording means 105 receiving this decision output 104 outputs the image data/? Image data is read from the y-fa 5, and a document is recorded and output based on this. Further, in step 217, for example, upon receiving a signal from the ROM, MPS, etc. indicating the end of page -, it is determined that page - has ended, and the process returns to step 210 to execute the subsequent operations in the flowchart.

When all of the transmitted data has been received in this way, the other party's facsimile machine sends a signal (for example, EOP) indicating that the transmission has ended. As a result, the process moves from step 210 to step 218, and the line is opened in response to the line disconnection command signal DCN sent from the other party's facsimile machine. After that, recording means 1
05Fi, in step 219, all the character codes left in the character code buffer 4 are sequentially read out and converted into image data via the character generator 10, and then the recording operation based on this is ended.

Therefore, conventionally, as shown in FIG. 4, every time data corresponding to page - of the original is received, a signal W is issued that instructs to stop transmitting data corresponding to the next page of the original.
AIT was sent out, and during this time, - was recorded and output, and then an OK signal was sent out to start sending the original manuscript. On the other hand, in this embodiment, as shown in FIG. 5, character code P is stored in character code buffer 4. When this reaches the World Cup (free space is less than a predetermined amount), an empty area is created in the character code buffer 4 in which the recording operation can be performed, and transmission to the other party's facsimile device is stopped only during this time. . Furthermore, when the data is transmitted using 14 image data, the recording operation is performed immediately, so that there is no need to increase the capacity of the image data transfer buffer 5. Furthermore, finally, after the line was disconnected, the character code buffer 4
The remaining character code P is read out and a recording operation is performed.

In the embodiment, the recording operation is performed only when the character code buffer 4 is full, but the recording operation is performed as soon as the character code buffer 4 is received, and the next recording data is stored in the character code no. The recording order determining means 101 may decide which of the data buffers 5 to read from, and the recording operation may be performed page by page.

In addition, in the embodiment, the free space information was obtained only for the character code buffer 4 and the memory capacity was determined. , the capacity of the image data buffer 5 is increased to the level of the original document teacher, free capacity information is also obtained from the image data buffer 5, and identification information indicating whether the received document is character code r or image data and the above-mentioned information are obtained. Based on the free capacity information of the two buffers, the buffer from which the next recording data should be read may be determined for each -page.

Furthermore, in advance, the control signal (control communication) of the hammer transmission control procedure is
If the order in which the data related to transmission is mixed into the character code P and image data and the respective capacities of the character code buffer and the image data buffer are given to the recording order determining means 101 by For example, the recording order may be determined based on these.

That is, the recording order determining means 101 determines the recording output so that the buffer does not become full, based on information on the current or future free capacity of each buffer and information on whether the transmitted document is character code or image data. This prevents a situation where transmission is stopped.

〔Effect of the invention〕

As explained above, according to the present invention, since the recording output is controlled so that the character code r and the image data in the data related to serial transmission are appropriately stored in the respective buffers,
The frequency with which transmission must be stopped as in the conventional method is significantly reduced, and therefore the line usage time can be shortened.
