(First Embodiment) FIG. 2 is a flowchart showing a first embodiment of the key telephone apparatus constructed as described above, and shows the operation of an answering machine function. The operation of the main part of the present invention will be described in detail according to this flowchart. First, the main device 10 shown in FIG.
From the incoming call detection operation by the main control unit 14 will be described. The main control unit 14 first determines whether an outside line is detected in step S21 of FIG. 2A during the execution of the interrupt processing, and when an outside line is detected, the absence mode is set to the key telephone device in step S22. It is determined whether or not it has been set.
Here, when the absence mode is set, the specific child device in the main storage unit 16 as if the speaker reception key of the operation input unit 24 was operated in the predetermined specific child device, for example, the child device 20A In step S23, the speaker reception key operation information is stored in the operation information memory for use, and the process ends.

When an outside line incoming call is detected during the absence mode in this way, the speaker reception key operation information is stored in the operation information memory for the specific slave unit. Thereafter, the main control unit 14
In the process shown in the flowchart of (b), the operation information memory in the main storage unit 16 is analyzed. That is, first, in step S31, it is determined whether or not the data in the operation information memory is speaker reception key operation information. If this is "Y", it is determined in step S32 that an outside line is being received. Here, when an outside line is being received, an outside line capturing process for capturing the outside line being received is executed in step S33 to respond to this outside line reception. Thereafter, by controlling the T-switch 17, a call path between the incoming call response outside line and the specific slave unit is connected, and a speaker receiving process of turning on the speaker 29 by transmitting a speaker ON signal to the specific slave unit is executed in step S34. I do.

Next, the main controller 14 determines in step S35 whether or not the absence mode has been set, and if the absence mode has been set, executes the absence recording process in step S36.
In the absence recording process of step S36, the T switch 17 is controlled to connect the recording / reproducing unit 15 to the incoming response outside line, and the recording / reproducing unit 15 is made to perform a reproducing operation to send a response message to the incoming response outside line. Then, after the transmission of the response message, the recording / reproducing unit 15 is made to perform a recording operation, and the message of the caller is recorded on the recording / reproducing unit 15 via the incoming line. Note that the data in the operation information memory in the main storage unit 16 is the speaker reception key operation information. At this time, if an incoming call to an outside line is not being made, another state process is executed by the switch S37. If the data in the operation information memory in the main storage unit 16 is not the speaker reception key operation information, a process corresponding to the other key operation information is executed in step S38.

As described above, in the first embodiment, when an outside line incoming call is detected during the absence mode, the speaker reception key operation information is stored in the operation information memory for the specific slave unit, and the operation information memory analysis processing is performed. When the speaker reception key operation information is detected, it is confirmed that an outside line is being received, the outside line is captured, a response is made to the outside line, and the path between the incoming response outside line and the specific child device is connected to connect the speaker 2 of the specific child device.
On the other hand, if the answering mode is in the answering mode, the path between the incoming response external line and the recording / reproducing unit 15 is connected, and a response message from the recording / reproducing unit 15 is sent to the caller via the incoming response external line. After sending the response message, the message message of the caller is recorded on the recording / reproducing unit 15.

In the first embodiment, since the speaker 29 of the specific slave unit is on, the response message sent from the recording / reproducing unit 15 in the absence recording process in step S36 and the recording to the recording / reproducing unit 15 are performed. The message message of the caller can be emitted from the speaker 29 of the specific slave unit, but the caller cannot respond off-hook to the caller. Further, when an incoming call arrives at one outside line, it is impossible for a plurality of slave units to simultaneously respond to an incoming call.

(Second Embodiment) FIG. 3 is a flow chart showing a second embodiment of the key telephone apparatus, showing the operation of an answering machine function. The operation of the second embodiment will be described in detail according to this flowchart.
