It is set whether to connect to the external telephone device 1 and this setting information is stored in the CPU circuit 5.

Next, the operation of the second embodiment when there is an incoming call from another telephone will be described with reference to the flowchart of FIG.

First, when an incoming call from a telephone is detected (S1
01), the ISDNi / f circuit 8 conveys this incoming call to the CPU circuit 5, and the CPU circuit 5 reads the above-mentioned setting information (S102).

If this setting is for the handset 12, the CPU circuit 5 checks whether the handset 12 is usable (S103). If it is possible, the call processing is performed (S107). , Telephone device 1
Is checked through the telephone i / f circuit 3 (S1
04).

If the telephone device 1 is usable, call processing is carried out (S107), and if not, the call is disconnected (S1).
08) and ends. If the setting is a telephone device in S102,
The CPU circuit 5 sends the telephone device 1 through the telephone i / f circuit 3.
It is checked whether or not can be used (S105).

If it is available, a call process using the telephone device 1 is performed (S107). If the telephone device 1 is unavailable, it is checked whether the handset 12 is available (S106).

Then, if available, the handset 1
Call processing using 2 is performed (S107). If it cannot be used, disconnection processing is performed (S108), and the processing ends.
Also, when the call processing (S107) is finished, the disconnection processing is also performed (S108), and the processing is finished.

On the other hand, the calling operation is the same as in the first embodiment when the telephone device 1 is used. The path of the voice signal in this case is telephone device 1 → TA circuit 2 → port switch circuit 7 → ISDN i / f circuit 8 → ISDN network line 9.

When making a call using the handset 12, the dial number is input from the operation panel 11 after the CPU circuit 5 detects the off-hook of the handset 12. The CPU circuit 5 passes the ISDN i / f circuit 8 by this dial number,
Call control with the network is performed, and the path of the voice signal is changed from the handset 12 to the A / D conversion circuit 13 to the port switch circuit 7 to I.
The SDN i / f circuit 8 is set to the ISDN network line 9 and the call processing is performed.

Is specified, and if the one specified at the time of the incoming call cannot be used, the other device is called. However, since there is only one A / D conversion circuit, the handset and telephone device cannot be used simultaneously.

Next, the configuration and operation of each circuit shown in FIG. 4 will be described in detail.

Telephone device 1, CPU circuit 5, image memory 6, ISD Ni / f circuit 8, operation panel 11

When the telephone device is used, the telephone device 1 → telephone i / f circuit 3 → analog switch circuit 15 → A / D conversion circuit 14 → port switch circuit 7 → ISDN i / f circuit 8 → ISDN network line 9 .

Next, a fourth embodiment of the present invention will be described.

Generally, in a facsimile machine, user data such as a one-touch dial is stored in a memory such as a RAM, and when replacing the facsimile machine with another facsimile machine or repairing it in case of failure, it is stored in the memory. After re-entering the user's user data into the facsimile machine that is about to be replaced or after repairing, after manually inputting it from the operation panel or using the communication line to temporarily store it in the memory of another facsimile machine , A method of transferring to the memory of the original facsimile machine and storing it again has been taken.

However, in the case of manually inputting from the operation panel as described above, it is troublesome by human hands. Further, when using a communication line, there is a drawback that a communication fee is required and, in addition, if the communication function of the facsimile apparatus fails, it cannot be used.

In view of this, in the fourth embodiment, the user data in the memory is printed out on paper as bar code data, is temporarily stored, and is then read by a scanner to analyze the bar code data. Thus, the user data can be easily rewritten by inputting the data into the memory of the same facsimile machine or another facsimile machine.

FIG. 5 is a block diagram showing this embodiment.

This facsimile machine has a memory 21 and
It has a CPU circuit 22, a bar code ROM 23, a character code ROM 24, an operation panel 25, a printer 26, and a scanner 27.

Next, the configuration and operation of each circuit shown in FIG. 5 will be described.

First, the memory 21 comprises a one-touch dial and a non-volatile RAM for storing user data and the like. The CPU circuit 22 includes a memory 21 and a bar code RO.
Each memory of the M23 and the character code ROM 24 is accessed, and each memory, the printer 26, and the scanner 27 are controlled by input from the operation panel 25.

The bar code ROM 23 stores bar code data and generates a bar code corresponding to user data. The character code ROM 24 stores character code data and generates a character code. is there.

The operation panel 25 is for inputting commands and data to the facsimile machine, and the printer 26 is controlled by the CPU circuit 22 so that the bar code data in the bar code ROM 23 and the character code ROM are controlled.
The 24 character data is output as an image. Scanner 27
Reads an image including a barcode.

Next, the overall operation of this embodiment will be described.

First, when an instruction to print out user data is given by operating a predetermined key from the operation panel 25, the CPU circuit 22 detects this and reads the user data from the memory 21.

Then, the CPU circuit 22 reads the bar code corresponding to the code information forming the user data and the character code forming the character string indicating the contents from the bar code ROM 23 and the character code ROM 24,
This is output from the printer 26 as image information. The character code used at this time is not used at the time of reading, but it helps the person to understand what the barcode means when viewed.

Next, when the user data output as a bar code as described above is to be input again, the printed paper is set on the scanner 27 and a predetermined key operation is performed on the operation panel 25. So C
When the PU circuit 22 detects this, it reads the image data from the scanner 27, detects the bar code in the image data, and compares it with the data in the bar code ROM 23,
Convert to user data. After that, the CPU circuit 22
The user data converted from the bar code is stored in the memory 21, and the process ends.

When the user data is printed out, only the bar code data may be output and the character data may not be output. This has the advantage that the paper required for printout can be saved.

[0061]

As described above, according to the first aspect of the present invention.
According to 2 and 2, by providing the interface of the PSTN network telephone device and the terminal adapter function in the G4 facsimile device, the PS4 network telephone device can be connected to the G4 facsimile device by the G4 facsimile device.
There is an effect that the communication service of the ISDN network can be used through the facsimile device and the PSTN network telephone device and the ISDN network can be effectively used.

According to the third aspect of the present invention, by having the function of outputting the user data as bar code data and the function of reading the bar code data, the facsimile machine alone replaces the user data in the memory of the facsimile machine. Therefore, there is an effect that the work can be simplified.
