Next, the operation of the simple exchange configured as described above will be explained.

First, the answering machine function body 10 and the extension telephones 5B, 5
C and 5D are extension terminals 45A, respectively, as shown in FIG.
, 45B, 45C, and 45D, and the door phone 15 is connected to a door phone terminal 57. Moreover, the answering machine function body 1 is placed in the first position by the doorbell response switching means 39i.
0 is set to away mode.

When a bell call is received from the outside line 1 in this state, the simple exchange automatically responds using the normal answering machine function. That is,
The call signal enters the reception circuit 22 of the simple exchange main body 20 and is further transmitted to the control device 30 via the photocoupler 23. Next, the control device 30 operates the bell generation circuit 41 to switch the bell switching circuits 44A, 44B, 44C, 44D.
via the answering machine function body 10. Extension telephone 5B, 5
Send a bell signal to C and 5D. Answering machine function body 10
When a bell signal is applied to the telephone answering machine 10, the answering machine function body 10 is activated, the receiver pick-up detection circuit 44A is activated, and the information is transmitted to the control device 30.

Subsequently, the control device 30 drives the relay circuit 46 to reverse the relay contact 47A, resulting in a DC closed state. Then, the answering machine function body 10 is connected to the outside line 1, and the answering machine function body 10 operates in response to an incoming call on the outside line 1.
The subscriber line response announcement is played back and the subscriber line message is recorded, and when the recording is completed, the system automatically returns to the recording standby state.

On the other hand, in the above setting state, the call button 16 of the doorbell 15
When pressed, the simple exchange automatically takes the following actions. That is, when a call signal is input to the control device 30 by pressing the call button 16, the call detection means 31 detects this and sends out a detection signal.

Based on this detection signal, the control device 30 controls the bell generation circuit 41
．． The standby signal generation circuit 50 is activated, and the bell signal is transferred to the bell switching circuits 43A, 43B, and 43C.

43D, answering machine function body 10. Extension phone 5B,
Send to 5C and 5D. At this time, the answering machine function body 10, which is set to the answering mode, starts operating and at the same time receives a skip signal from the standby signal generation circuit 50, and suppresses the transmission of the reproduction signal of the response announcement for the subscriber line. As the operation progresses, a beep tone is sent out at the end of the response announcement.

Beep tone detection circuit 52 detects the beep tone and sends it as a signal to controller 30. The answering set determination means 33 of the control device 30 receives the signal and determines that the answering machine function body 10 is set to the answering mode C.
Thereby, the control means 35 operates the doorbell response announcement sending means 40.

As a result, the doorbell response announcement converted into an electric signal is transmitted to the signal switching circuit 54. The answer announcement is sent to the door phone 15 via the door phone circuit 56, and the door phone 15 converts it into a sound and amplifies the response announcement.

On the other hand, when the answering set determining means 33 determines that the answering mode is set, the standby signal generating circuit 50 outputs a standby signal and puts the answering machine function unit 10 in a recording standby state.

Then, when the transmission of the doorphone response announcement ends, the doorphone response announcement sending means 49 stops operating under the control of the control device 3o, and the standby signal generation circuit 50 stops outputting the standby signal. As a result, the answering machine function body 10 starts recording, the door phone message recording time setting means 37 starts a timer and continues calculating the recording time, and the message input from the door phone 15 is recorded on a recording tape. .

When the door phone message recording time setting means 37 reaches a predetermined door phone message recording time, the control device 30 sends out a control command and opens the relay contact 47A (switches to the dotted line side). Thereby, the answering machine function body 10 and the door phone 15 are disconnected, and the answering machine function body 10 returns to the original recording standby state.

Further, a simple exchange in which the answering machine function body 10 is set to the answering mode and the door intercom response switching means 39 is set to the second position operates as follows.

Since the door phone response switching means 39 is in the second position, the answering machine function body 1 responds to a call from the door phone 15.
0 is in an inactive state, and the operation control of the doorbell response announcement sending means 40 by the control means 35 is in an off state. Then, when there is a call from the door phone 15, the control device 30 operates the bell generation circuit 41, and a bell signal is sent out.

Note that the present invention is not limited to the configuration of the above-described embodiments, and the embodiments thereof can be changed without departing from the technical idea of the present invention. For example, the answering machine function body 10 may be built into the simple switchboard main body 20 and configured integrally. Further, the answering machine function body 10 may be controlled by providing a control line separate from the telephone line.

Furthermore, the answering announcement for the doorbell may be an announcement message recorded in the answering machine function body 10 and separately from the answering announcement for the subscriber line.

Further, the control of the bell generating circuit 41 in the second position of the intercom switching means 39 can also be performed by changing the period of the ringing from that of an incoming call, or by changing the frequency of the ringing.

Further, it may be configured such that when an incoming call from the outside line 1 is received while answering the answering call to the doorbell 15, a message for temporarily stopping the doorbell answering can be sent.

<Effects of the Invention> As explained above, according to the simple switchboard of the present invention, when the subscriber is absent and the answering machine function body is set to the answering mode, when there is a visitor and a call is made from the doorbell, the subscriber A doorbell response announcement separate from the corresponding message corresponding to incoming calls on the line is sent, so it will notify you when you are away.
It is possible to respond automatically by making a response announcement instead of a response announcement such as .

In addition, by providing a fixed recording time for recording message messages from the doorphone, which is separate from subscriber line message messages, when the message message from the doorphone is finished, the recording may be interrupted due to outdoor noise. It is possible to prevent invalid recording for a long time without having to continue recording.

Furthermore, by providing a door response switching means, it is possible to stop the sending of a doorbell response announcement when a call is made from the doorphone while the user is absent, and also to stop the automatic response of the answering machine function body. Furthermore, even if the user forgets to cancel the answering machine's answering mode setting after returning home, the presence of a visitor can be recognized by the ringing of the doorbell.
