The reference numeral 90 is a telephone connected to the NCU 80. 9
Reference numeral 1 is an off-hook detection circuit that detects that the handset of the telephone 90 has gone off-hook.

On the other hand, reference numeral 110 denotes a power supply circuit which supplies a power supply voltage to each block via a power supply line (not shown).

Next, a method of using a telephone using the operation panel in the facsimile apparatus configured as described above will be described.

First, the method of registering the telephone number of the other party will be described.

In this case, when the number registration key is pressed from the group of function keys 3 on the operation panel 2, the device enters the registration mode and the display on the panel is used for one-touch registration as shown in FIG. The operating procedure is displayed.

In the case of the example shown in FIG. 3, A which is a group of one-touch keys 5
You can register up to 20 digits of telephone numbers in 24 places up to X.

As shown in FIG. 3, a registration example display field 7 and an operation procedure display field 8 are displayed on the display unit 6. Therefore, if the operator registers the telephone number in the steps as instructed in these fields, each alphabet will be displayed. One-touch dialing can be registered for.

The registered telephone number is stored in the RAM backed up by the battery in the system control circuit shown in FIG.

While registering, the operator writes the name of the other party on the portion of the display plate 5a of A to X of the group of one-touch dial keys 5.

After the registration of the telephone number is completed in this manner, the operator can call the other party by pressing the alphabet key in which the name of the other party is written, as described later.

On the other hand, speed dial registration is performed as follows.

That is, first, when a speed dial key is selected from the group of function keys 3 and pressed, a display as shown in FIG.

This display includes a display field 7 and a registration procedure display field 8 of a registration example similar to the case of one-touch dial registration, and the operator can register the speed dial only by operating the ten keys 4 according to this procedure.

In the case of this example, it is possible to register up to 20 digits of telephone numbers from the code “01” to “50” for 50 speed dials.

These speed dial numbers are also stored in RAM in the system control circuit.
Memorized in.

After the registration of the speed dial is completed, the operator can call the other party by inputting the code corresponding to the other party by the ten keys 4.

Here, the telephone number is similarly registered regardless of whether the other party is a facsimile machine or not. The facsimile telephone number and the normal telephone number may be configured so that the storage locations in the memory are different and the system control circuit automatically determines this.

Now, the specific operation will be described with reference to the flowchart of FIG.

(Steps S1 to S5) First, when using the one-touch dial, as shown in the upper left half of FIG. 5, press one of the one-touch dial keys 5 of A to X, for example, the "A" key. When the button is pressed, the telephone number registered in "A" is displayed on the display as shown in FIG. 6 (A), and at the same time, characters such as "Dial Chu" indicating that dialing is in progress are displayed.

During this time, the main control circuit 60 calls the other party by the line 1 from the NCU 80 via the dial pulse generator 100 without using the modem 70.

(Steps S6 to S9) If the operator picks up the handset after the above-mentioned display is made and while the display is being made, that is, while dialing by the dial pulse generator, after the dialing is completed, the telephone is called via the NCU. You can have a conversation by connecting the line to a telephone.

On the other hand, if there is no off-hook during dialing, the dialing display disappears after dialing ends. Then, the telephone line is connected to the modem 70 by the NCU 80. Further, the presence or absence of a document is detected by the document detector 24, and if there is a document, the apparatus shifts to the transmission mode, and if there is no document, shifts to the reception mode.

In the case of using the speed dial, as shown in the lower right half of FIG. 5, first press the “*” key on the numeric keypad 4, and then press the speed code using the numeric keypad 4.
As shown in FIG. 3B, a telephone number corresponding to the shortened code and "Dial Chu" are displayed.

In this state, a call can be made by picking up the handset as in the case of one-touch dialing.

In this way, a normal call can be made without using the changeover switch.

By the way, when the user wants to make a call to the first call destination, he / she may dial the telephone or use the numeric keypad 4 of the facsimile.

Further, the telephone mode can be switched to the call mode only during dialing, but it may be configured to be switchable until a fixed time elapses after completion of dialing.

[Effect] As is apparent from the above description, according to the present invention, in a facsimile apparatus having an automatic transmission function in an on-hook state, during transmission of a dial signal for automatic transmission or within a predetermined time after completion of transmission. By switching the telephone off-hook, the call mode is switched without using the call switching key. In other words, the on-hook dial function is used to switch to the handset call during on-hook dialing or after-dial off-hook. There is an excellent effect that it is possible to switch between call and communication.
