The second function is to erase information data stored in the storage circuit 24.

In this embodiment, the erase mode is set by pressing the key "F" on the operation unit 30 and then pressing "2". The method of address specification is the same as in the case of the recording/playback mode described above, by pressing the number keys corresponding to "Show" and "Base". When part of the information data stored in the storage circuit 24 is erased, the remaining information data is rearranged in chronological order.

The third function is to obtain a list of source information of all received data stored in the storage circuit 24. To set this mode, it is sufficient to press the key "F" and then the key "3" from the operation unit 30.

In this way, by printing a list of source information and viewing it, it is possible to select the source of received data that needs to be recorded or erased. Note that when the storage circuit 24 overflows, the overflowed data via the signal line 24b selectively controls the control circuit 34.

The received data is sent to the hybrid circuit6. Once the information data reaches the storage circuit 24 and the recording circuit 26 via the demodulator 20° decoding circuit 22, if the device is set to manual reception mode, the information data is manually transferred to the recording circuit 26 through the previous procedure. Print immediately. Further, when the present device is set to the automatic call receiving mode, the received data is temporarily recorded in the memory circuit 24. Thereafter, after finishing the post-procedure, the recording circuit 26 prints the sender information (date, time, caller's telephone number, sender's user name, number of originals). When the operator determines that the data is necessary by looking at the source information, the operator uses the first function described above to transfer the data from the storage circuit 24 to the recording circuit 26 and record/playback (print) it. conduct.

What page of the communication is it?) to the signal line 34e, and then outputs a pulse to start erasing the stored data. Supplies to 34 signal lines.

In step 550, it is determined whether or not the mote for recording and reproducing the source information of all the information data stored in the storage circuit 24 can be selected, that is, whether or not the key rF''r3J of the operation section has been pressed. Ru. When the mode for recording and reproducing all the source information stored in the storage circuit 24 is selected, that is, when the keys "F" and "3" of the operation section 30 are pressed, the process advances to step 552. On the other hand, when the mode for recording and reproducing all the source information stored in the storage circuit 24 is not selected, that is, when the keys "rF, r3" are not pressed, the process advances to snap S54.

In step 552, all source information stored in the storage circuit 24 is recorded and reproduced. That is, the control circuit 34 outputs a signal of signal level "1" to the signal line 34f, outputs all the source information stored in the storage circuit 24 to the signal line 34h, and then outputs a recording start pulse to the signal line 34g. supply.

When the facsimile transmission is completed, the telephone line is reconnected to the telephone side.

The embodiments described above are configured so that the portion to be recorded, reproduced, or displayed can be selected on a page-by-page basis, but the page may be further subdivided so that any portion within the page can be selected.

Further, in the above-described embodiment, when the storage circuit 24 overflows, the oldest information data is erased. However, when the storage circuit 24 overflows, the overflowed data is transferred to the recording circuit 26. It is also possible to record and play.

Furthermore, in the embodiments described above, decoded data is stored in the storage circuit, but encoded data before decoding may be stored.

In the previous embodiment, the received data is stored in the storage circuit only when the automatic call reception mode is set, and the data is not immediately recorded and reproduced. When the switch is in the closed state, it is also possible to store the data received in all reception modes in the storage circuit 24 (that is, not to immediately transmit it to the recording circuit 26). Conversely, when this switch is in the open state, it is also possible to record and reproduce data received in all reception modes in the recording circuit 26, but not to store it in the storage circuit 24.
