The second switch circuit 24 is switched in conjunction with the operation of picking up the handset 27, and a foreign message (call signal) coming in after the call signal is supplied to the handset 27 via the call circuit 26 to make a call. It becomes possible state.

Further, the first switch circuit 23 is switched when a call signal comes in while it is set to the answering machine recording state, whereby the detection circuit 28 and the recorder 29 are connected to the external terminal 21.

The detection circuit 28 detects that a call signal has been received, and supplies a detection output to a control circuit 30 which is the number display circuit in the present embodiment.

The control circuit 30 is supplied with a clock pulse of a predetermined frequency from the oscillation circuit 31.

Here, the control circuit 30 is connected to the input / output ports 301 and 302 and the CPU.
When the detection output is supplied to the CPU 303 through the input port 301, the operation program stored in the ROM 305 is executed based on an instruction from the RAM 304. At the same time, the clock pulse is counted by the timer 306, and various command signals are output from the output port 302 at a predetermined timing.

That is, the control circuit 30 transmits the transmission command signal to the audio ROM 3
2 and from this voice ROM 32, "I'm away now ...."
Etc. is output. Then, the transmission message is transmitted from the external line terminal 21 to the other party via the bridge circuit 22.

The light emitting element 34 corresponding to the numeric key corresponding to the number of the number of the foreign message is turned on based on the instruction of the number display signal.

The number of foreign messages in the present embodiment is obtained by counting the predetermined time by the timer 306 as one unit (one case), and the number is incremented each time a foreign message arrives, and the corresponding numeric keypad is used. By flashing, the number of calls received while you are away is displayed.

Next, the operation of the telephone device configured as described above will be described with reference to the flowchart shown in FIG.

First, it is detected whether or not a call signal has arrived (step 1), and if not, the reception standby state is maintained (step 2).

When a call signal arrives, the system waits until the tone pulse is emitted three times (step 3), and then enters a receiving state (step 4) to transmit a transmission message (OGM) (step 5).

Then, it waits for the end of the transmission of the transmission message (step 6). When the transmission is completed, a transmission signal, for example, "P" is transmitted (step 7).

Thereafter, the timer is started (step 8), and the recorder 29 is set to the recording state (step 9).

Then, it is checked whether or not the line is connected to the other party (step 10).
At step 6, it is detected whether or not a predetermined time has elapsed by counting clock pulses (step 11). If no connection is established, the process returns to step 2 to enter a reception standby state.

Here, it is detected whether or not there is a light-emitting element that is already lit (step 12). If there is, the light-emitting element that is lit is turned off (step 13), and the number of the numeric keypad corresponding to the light-emitting element is further detected. The light emitting element corresponding to the numeric keypad having a number which is larger than the number key by one is newly turned on (step 14).

If no light emitting element has already emitted light, the light emitting element corresponding to the numeric keypad of "1" is turned on (step 15).

Then, it is determined whether the connection with the other party has been disconnected (step
16) If the recording is not stopped, the recording state is maintained (step 17). If the recording is stopped, the recording state is stopped (step 17).
18) Maintain the state where the numeric keypad corresponding to the number of foreign messages is illuminated (step 19).

Then, it is determined whether or not the absence recording state has been canceled (step 20). If the answering state has been canceled, the light emitting element is turned off (step 21), and the process returns to step 1 again. To end the series of operations.

As described above, according to the telephone device of the present embodiment, since the numeric keypad of the number of the foreign message is illuminated, the presence or absence and the number of the foreign message can be immediately known.

(Effect of the Invention) According to the present invention, when a call signal arrives at the telephone device, the incoming call display circuit detects this, and the light emitting elements that illuminate the numeric keypad are stored in the storage circuit in a predetermined order. By turning on or blinking sequentially, the visibility of the call signal can be greatly improved, and the order of lighting or blinking of the light emitting elements can be changed by changing the contents stored in the memory circuit.
