DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The operation of the storage type facsimile apparatus according to the present invention when transmitting is described below in detail with reference to FIG. FIG. 1 is a block diagram showing an embodiment of the present invention. Here, the thick connection lines in the figure are image data buses, and the thin connection lines are control signals.

The contents written on the original are read by the scanner unit 5 and subjected to image processing. The image-processed data is compression-encoded and written in the image memory 4 as image data.

The control unit 1 as a control means sends a transfer control signal to the image memory 4 and the secondary storage device 8 to transfer the image data written in the image memory 4 to the secondary storage device 8 in block units. , Accumulate. After the transfer and storage of the image data to the secondary storage device 8 is completed, the image data is stored in the image memory management information table (not shown) stored in the document management information memory 10 in the secondary storage device. The code information indicating that the data is stored in No. 8 is written. As a secondary storage device,
For example, a hard disk or the like is used. Document management information stored in the image memory 4 and the secondary storage device 8 is stored in the document management information memory 10. The document management information memory 10 is a non-volatile memory and is incorporated in the control unit 1.

The control unit 1 transfers the image data written in the image memory 4 to the secondary storage device 8 in block units and stores the image data. After the image data is transferred to and stored in the secondary storage device 8, the control unit 1 stores the secondary storage device 8 in an image memory management information table (not shown) stored in the document management information memory 10. The code information indicating that the data has been stored is written. 2
For example, a hard disk is used as the next storage device.

After all the code information is written in the image memory management information table, the image data stored in the secondary storage device 8 is transferred to the image memory 4 by the control unit 1, and the transferred image is transferred. The data is read from the image memory 4, and the read image data is transferred to the communication unit 7. In the communication unit 7, the image data is decoded and compression encoded,
The compression-coded image data is transmitted to the other terminal.

Next, the operation for printing will be described. The control unit 1 refers to the image memory management information table and checks whether the image data to be read is stored in the image memory 4.
After that, when the image data to be read is stored in the image memory 4, the control unit 1 reads the image data as it is and sends the read image data to the printer unit 6. The printer unit 6 performs image processing such as decoding on the read image data, and prints out on recording paper.

On the other hand, when the corresponding image data does not remain in the image memory 4, the secondary storage device 8
The corresponding image data is read in block units from and is once transferred to the image memory 4. The transferred image data is read from the image memory 4 and sent to the printer unit 6, where the printer unit 6 performs image processing such as decoding of the image data as described above, and then prints out on a recording paper.

When a failure occurs in the secondary storage device 8, a failure occurrence signal is sent from the secondary storage device 8 to the control unit 1.
Upon receiving the failure occurrence signal, the control unit 1 once resets the entire facsimile apparatus and restarts it. afterwards,
The control unit 1 reads a list of documents including image data that cannot be read from the secondary storage device from the document management information memory 10, and prints out the image data that cannot be read from the secondary storage device. After that, the transfer processing between the image memory 4 and the secondary storage device 8 is stopped, and each operation is executed simply by writing and reading in the image memory 4. That is, the control unit 1 performs writing and reading control to and from the image memory 4 and transfer control between the image memory 4 and the secondary storage device 8 as independent processes, respectively.
Even if a failure occurs in the next storage device, even if the transfer process between the image memory 4 and the secondary storage device 8 is stopped, the writing and reading to and from the image memory 4 are simply performed as they are. The accumulation operation and the transmission operation are continuously executed as they are.

When the power supply is cut off, the backup circuit 3 is activated to supply power to the image memory 4 from the backup battery 2 as a backup power supply so that the memory contents can be retained.

[0016]

According to the present invention, even if a failure occurs in the secondary storage device, the entire facsimile apparatus is reset once and restarted, so that the accumulation operation and the transmission operation as a facsimile are continued. It is possible to avoid an inconvenient state in which the device is not used at all until it is executed and the maintenance staff takes action.
