The operation of the facsimile apparatus in the embodiment having the above configuration will be described below with reference to the related drawings.

First, the operation of storing the received image data on the diskette 16 will be described with reference to the flowchart shown in FIG. When the NCU 3 detects an incoming call from a partner device via a line (not shown), the central control unit 20 controls the modem control unit 5 according to a facsimile transmission procedure to start a process of receiving image data. In step S1, it is checked whether or not there is a recording sheet, and if there is a recording sheet, the received image data is printed on the recording sheet. However, if there is no recording paper, the process proceeds to step S2, and proxy reception to the image memory 11 is performed. Then, receiving predetermined image data,
If the remaining capacity of the intermediate image memory 11 is exhausted, step S3 is executed.
The process proceeds from step 4 to the error process. If all the data has been received, the process proceeds from step 4 to step 5, and the remaining capacity of the diskette 16 is checked. As a result, if there is not enough space left to store the received image data, the process proceeds to step S6, where the diskette 16
Is displayed on the display 7 and the process is terminated.

However, if the remaining capacity is sufficient, step S
7 and transfer the received image data in the image memory 11 to the diskette 16. When the transfer is completed, the process proceeds from step S8 to step S9, where management data as shown in FIG.
To memorize. That is, the code indicating the alternate reception is stored in the type area 24 of the received image, and the output presence / absence area 25 is stored.
Stores a code indicating none (not output). Also,
The created management data is stored in the system memory 1 shown in FIG.
2 is also stored as management data.

By storing the received image data on the floppy disk in this manner, the data can be retained on the diskette 16 even when the facsimile is turned off, and when the remaining memory capacity of the diskette 16 is exhausted. By replacing the diskette, the memory capacity of the facsimile can be increased infinitely.

Next, the processing when the diskette 16 storing the image data is inserted by proxy reception will be described below with reference to the flowcharts shown in FIGS.

First, when the FDC 14 detects that the diskette 16 has been inserted, the central control unit 20 proceeds to step S11 shown in FIG. 4 to determine whether or not there is data stored in the inserted diskette 16. Check. This process is a process of reading the management data of the diskette 16 and checking whether the number of the image data is stored in the number area 23 of the received image. The result is determined in step S12. If the stored data does not exist, the process proceeds to the initial setting shown in FIG. 7, and the initial setting is performed to newly use the diskette 16 as a memory for a received image. . In steps S41 and S42 of FIG. 7, the numbers specific to the image receiving apparatuses and the numbers of the diskettes allocated to the diskettes 16 by the apparatus are stored in the management data areas 21 and 22 shown in FIG. In step S43, in addition to this information, the management data indicating that the diskette 16 having the above-mentioned number exists and is currently inserted into the apparatus is stored in the system memory 12.

On the other hand, if the data stored in the diskette 16 exists in step S12 in FIG. 4, the process proceeds to step S13, and the image data is stored in the image receiving device unique number area 21 with reference to the management data. Check that it was received by the device. As a result, if the received image data is not the image data received by the own device, the process proceeds to a process of printing image data stored by another device, which will be described later with reference to FIG. However, if the image data is received by the own device, the process proceeds to step S15, and it is determined whether or not the image data has not been output with reference to the received image output presence / absence area 25 of the management data. here,
If not, the process proceeds to a recording process described later. If not, the process proceeds to step S16, and the image data is output by another device with reference to the received image output number area 26 of the management data. Judge whether it is. As a result, if the data is output by the own device, the process is terminated. If the data is output by another device, the process proceeds to step S17, where the management data of the system memory 12 and the diskette 16 shown in FIG. Compare management data. Then, step S1
In step S8, it is determined whether or not they match, and if they do match, the process ends. If they do not match, the process proceeds to step S19, and the management data of the diskette 16 is stored in the system memory 12. In the next step S20, the contents of the stored management data are displayed on the display unit 7 or printed by the recording unit 2, and the user is notified of the updated data, and the process is terminated.

Next, the case where the data is stored in another device in step S14 of FIG. 4 will be described below with reference to the flowcharts shown in FIGS.

First, in step S21 of FIG. 5, the management data of the diskette 16 is stored in the system memory 12, and the contents are displayed on the display 7. Next, step S
At 22, it is determined with reference to the received image type area 24 of the management data whether the data is image data received by proxy reception. As a result, if it is not an alternate reception, the process ends as it is,
If so, the process advances to step S23 to record the image data. In this step S23, it is checked whether or not recording paper is set in the recording section 2. If there is no recording paper, the process proceeds to step S24, and the fact is displayed on the display device 7. Thereafter, the process waits for the setting of the recording paper in steps S25 and S26. If the diskette 16 is removed during that time, the process proceeds from step S26 to step 27 to delete the management data in the system memory 12 and return to FIG. The following removal processing is performed.

The detaching process is a process of storing information indicating that the diskette 16 has been removed in step S51 of FIG. In this process, a code indicating that the diskette is being removed is set in the diskette leaving area 28 of the management data shown in FIG. 11, and the time input from the clock IC 17 is set in the diskette leaving time area 29. In step S52, the contents of the management data are displayed on the display unit 7 or printed by the recording unit 2 to notify the user. Also, in the above-mentioned step S52, the predetermined KE
It is also possible to configure so as to wait for Y8 to be pressed and display or print.

On the other hand, if the recording paper is set or set in steps S23 and S25 in FIG. 5, the process proceeds to step S28, and the recording unit 2 is started to start printing image data. Next, in step S29, the remaining recording paper is checked. If the remaining amount of recording paper is small, printing is stopped, and predetermined error processing is performed. However, if printing is completed, the process proceeds from step S30 to step S31, and predetermined information is stored in the management data of the system and the diskette 16. Specifically, the number of the own device is set in the received image output device number area 26, and a code indicating output has been set in the received image output presence / absence area 25. The time when the image data was printed is input from the clock IC 17 and set in the data processing time area 27 shown in FIG. Then, the process proceeds to step S32, where the contents of the management data shown in FIG. 10 are displayed on the display device 7, and the process ends.

FIGS. 12 to 14 show the state of the image data on the diskette described above. Here, FIG. 12 is a diagram showing management data and its image data by alternate reception that are received and stored by another device,
