The NCU (class controller) 8 has a function of transmitting a selection signal (pulse or tone dialer), and performs not only an automatic incoming call operation and a line control operation by detecting a ringing tone, but also a telephone under the control of the system control unit 1. An operation of transmitting a selection signal to the line 12 is performed.

The handset 13 performs a call, and the off-hook detection sensor 14 detects off-hook of the handset 13.

FIG. 2 is a flowchart showing an operation example of this embodiment.

The non-volatile RAM 6 includes a selection switch 4A of the operation unit 4.
And a telephone number "X" for facsimile and a telephone number "Y" for telephone call are allocated and registered in advance.

First, it is determined whether or not the selection switch 4A disposed on the operation unit 4 has been pressed (S1).
The system controller 1 determines whether the handset 13 is off-hook or on-hook according to the output of the off-hook detection sensor 14 (S2).

If the off-hook detection sensor 14 determines that the handset 13 is on-hook, then the system control unit 1 determines the presence or absence of the transmission document 11 according to the output of the document presence sensor 10 (S3).

Here, when it is determined that the transmission original exists, the nonvolatile RA
The destination telephone number "X" for facsimile is read from M6, a selection signal of the telephone number is transmitted from the NUC 8 to the telephone line 12, and after the line is connected, the operation mode is changed to the facsimile transmission mode and a predetermined transmission operation is performed. (S4).

If it is determined in S3 that there is no original, the facsimile destination telephone number "X" is read out from the nonvolatile RAM 6, and a selection signal of the telephone number is transmitted from the NCU 8 to the telephone line 12, and the line connection is established. Thereafter, the operation mode is changed to the facsimile polling reception mode, and the reception operation is performed (S5).

On the other hand, when the off-facsimile detection sensor 14 determines that the handset 13 is off-hook, the system control unit 1 determines the presence or absence of the transmission document 11 according to the output of the document presence sensor 10 (S6).

If it is determined that there is a transmission document, the nonvolatile RAM 6
Reads out the telephone number "X" of the facsimile destination, sends a selection signal of the telephone number from the NCU 8 to the telephone line 12,
After the line connection, the operation mode is changed to the facsimile manual transmission mode, and a predetermined transmission operation is performed (S7).

If it is determined in S6 that there is no original, the telephone number "Y" for the call is read out from the nonvolatile RAM 6,
The telephone number selection signal is transmitted from the NCU 8 to the telephone line 12, and the operation mode becomes the normal telephone mode (S8).

As described above, according to this embodiment, the presence / absence of a document and the hook state are provided as conditions for selecting the selection signal, so that the facsimile polling reception mode or the facsimile manual transmission mode is selected using the auto dial function. can do.
