Abstract

PURPOSE:To properly respond to a visitor by allowing a doorphone set to enter an extension number of a key telephone set desired to be called so as to call an optional telephone set and outputting a voice message preset to the doorphone set when the telephone set is set to the automatic answering mode. CONSTITUTION:A call signal is sent to a master set 1 through the depression of a key section 11 of a doorphone set 10 and a ten-key dial section 12 and an extension number in a key telephone set desired to be called and dialed and the data is also sent to the set 1. A detection circuit 3 receives a call signal from the set 10 via an interface circuit 2 and a switch section 6 and it is sent to a control section 4. The control section 4 sends the data from the set 10 to a dial identification section 5, which identifies an extension number and designates, e.g. a telephone set 20 based on the obtained data. The call is commanded to the telephone set 20 in this way and the set connects to a signal line of the set 10. In this case, when the switch 23 is set to the automatic answering mode, a message storage section 22 is started to store the message.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a key telephone device, and more particularly to a key telephone device in which a main unit accommodates a door intercom device and a plurality of key telephones.

[Conventional technology]

Conventionally, in this type of key telephone device, the key telephone device is called from the doorbell device via the main device, and when the key telephone device receives a calling signal, a ringing tone “ping-bong sound” is emitted.
It was configured to send out .

[Problem to be solved by the invention]

The above-mentioned conventional key telephone device has a structure in which the door phone calls the key telephone via the main device, and when the key telephone receives a ringing signal, it sends out a ringing tone (ping-pong tone). The disadvantage is that if the called party is away at the time of the call, the call cannot be answered.

[Means to solve the problem]

The button telephone device of the present invention is a button telephone device in which the main device accommodates a doorbell device and a plurality of button telephones, wherein the doorphone device has a call key unit that sends out a calling signal and an extension number of the keyphone device that inputs an extension number of the keyphone device. The main device includes a dial unit and a speaker that receives and outputs a voice message from the key telephone, and the main device includes a detection circuit that detects a calling signal from the doorbell device.
a dial identification section that identifies which extension number of a button telephone the input dial corresponds to; and a dial identification section in which the detection circuit receives a call signal and sends a dial to the dial identification section, and a button corresponding to the extension number identified by the dial identification section. a control unit that controls the telephone to make a call; the button telephone has a sound source that emits a ring tone when called from the doorbell device; a switch that sets home or away; and a switch that sets the home or away setting; and a message storage section in which a voice message to be sent to the door intercom device is stored in advance.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, the button telephone device of this embodiment includes a main device 1 that accommodates an intercom device 10 and a button telephone 20. As shown in FIG.

The doorbell device 10 includes a key unit 11 that sends out a calling signal.
, a numeric keypad dial section 12 for inputting the extension number of the key telephone to be called, a speaker 13, and an interface circuit 14 for interfacing with the main device 1.

The button telephone 20 includes a sound source 21 that emits a ringing tone "ping-bong sound" when it receives a call from the door intercom device 10, a switch 23 that sets whether you are home or away,
A message storage section 22 that stores in advance a voice message to be sent to the door intercom device 10 when the switch 23 is set to be away, an interface circuit 24 that interfaces with the main device 1, and a control section 25 that controls the entire key telephone 20. It has

The main device 1 includes an interface circuit 2 that connects the door intercom device 10 and each key telephone 20 and sends and receives signals, a detection circuit 3 that detects a calling signal from the door intercom device 10, and which key telephone device the input dial corresponds to. dial identification unit 5 for identifying whether the extension number is
The switch section 6 is connected so that messages can be sent from the telephone 20, and the detection circuit 3 receives the call signal and sends the input dial to the dial identification section 5.
A control section 4 is provided for controlling the key telephone to call the extension number identified by the dial identification section 5.

Next, the operation of this embodiment will be explained.

The operation of calling the key telephone 20 which is set to be away from home from the doorbell device 10 will be described.

By pressing the key part 11 of the doorbell device 10, a call signal is sent to the main device 1, and the numeric keypad dial part 1
2 and the extension number of the key telephone that you wish to call, and send the dial data to the main device 1. For example, from the numeric keypad dial section 12, "l l II,""2,""
0".

The detection circuit 3 receives a calling signal from the door intercom device 10 via the interface circuit 2 and the switch section 6, and outputs the calling signal to the control section 4.

When the control unit 4 receives the call signal from the detection circuit 3, it receives dial data “1” and “2” from the door intercom device 10 via the interface circuit 2.

``°0'' is received, and the dial data ``1'', ``l 2 II, and 0°'' are sent to the dial identification section 5.

The dial identification unit 5 receives the input dial data ""1n
, "2', 0°" are the extension numbers of which key telephone, and the identified data "key telephone 20°" is sent to the control unit 4.

The control unit 4 receives the identification data of the button telephone 20 to be called from the dial identification unit 5, instructs the button telephone 20 to call through the interface circuit 2, and controls the switch unit 6 to call the button telephone 20. and the signal line of the door intercom device 10 are connected.

When the control section 25 of the button telephone 20 receives a call from the main device 1 via the interface circuit 60, it sends out a ring tone "ping pong" from the sound source 21 and activates the message storage section 22 if the switch 23 is set to be away. and send a preset voice message (for example, [
I'm away at the moment. I will not be returning home until after 6pm, so if you are sending items, please deliver them to the Nichi-san next door. Thank you in advance.'') is sent to the main device 1 via the interface circuit 24.

The transmitted voice message is sent to the switch section 6 in the main device 1.
, is output to the speaker 13 via the interface circuit 2 and the interface circuit 14 of the intercom device 10.

〔Effect of the invention〕

As explained above, the present invention calls any key telephone by inputting the extension number of the key telephone to be called from the dial section of the door intercom when calling from the door intercom, and when the called key telephone is set to be away. By setting the door phone in advance to output a voice message, even if the called party is away, the preset voice message from the button telephone will be sent to the door phone, so that the visitor can This has the effect of allowing appropriate responses to be taken.
