Abstract

PURPOSE:To attain talking between a gate door and a destination by providing a telephone set using a call signal generated by the operation of a call bell switch of an interphone slave set side so as to apply external line callout in response to the set telephone number. CONSTITUTION:An interphone slave set 1 provided to a gate door of a house is connected to a terminal 4a of a visit changeover switch 4 of a master set side 2 through a wire 3. When a resident visits to the outside, the switch 4 is changed over to the visit terminal 4c and a destination telephone number is stored in a destination number setting circuit 5 at the time of visiting, a call signal reads a set number stored in the destination number setting circuit 5 together with the call bell of a visitor and it is sent to a transfer circuit 8 to call telephone set of said set number.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an intercom device, which is particularly capable of connecting to an external telephone and making a call when necessary.

Conventional technology In recent years, intercom devices for home use with visitor notification and crime prevention functions have become popular.Usually, a video camera and microphone are placed on the side of the main unit at the entrance, and a doorbell is used to communicate with the main unit indoors. It is now possible to monitor video and communicate with each other.

Problems to be Solved by the Invention However, with such a device, if the person is not home, the visitor only knows that the person is absent, cannot know where the person is going, and cannot relieve the visitor. Unable to do so, he simply returned home. In consideration of such cases, there is a visitor recording device that records the face of the visitor along with the doorbell when the person is away, and the person in the house who returns home can play it back and check the visitor's face. I can do it, but I only find out about the visitor after I get home, and if it's an important visitor or there's an emergency, it takes a lot of time to find out what's going on. It was something. The present invention solves the above-mentioned problems, and is configured so that when necessary, the intercom handset is connected to a preset destination telephone, and a conversation can be made between the intercom handset and the telephone. This is what I did.

Means for Solving the Problems The present invention provides a means for setting a destination telephone number, and a ring signal generated by operating a ring switch on the side of an intercom handset to call an outside line according to the set telephone number. a telephone set for transmitting a message, a voice generating means for transmitting a pre-stored message to the intercom slave unit in response to the doorbell signal, and a voice generating means for transmitting a pre-stored message to the intercom slave unit after the voice signal is sent by the voice generating means, the telephone set and the intercom slave unit It consists of a means for making the communication circuit conductive.

Effects According to the above configuration, when a visitor rings the doorbell from outside the residence using the intercom, even if the person at home is not home, the doorbell will be ringed by simply registering the external telephone number of the destination before the person leaves the house. Accordingly, the registered outside line calling operation is performed, and a conversation can be made between the intercom and the outside line.

Embodiments Hereinafter, intercom devices according to embodiments of the present invention will be described with reference to the drawings. The drawing is an electrical block diagram of an intercom device according to an embodiment of the present invention, in which an intercom handset 1 installed at the entrance of a dwelling unit is connected to a terminal 4a of a going out switch 4 on the main unit side 2 through a wiring 3. There is.

When a resident is present, this switch 4 is normally in position 4b, and the alarm is generated when a visitor operates the doorbell.

The notification sound generation circuit 6 outputs a doorbell signal as a visitor notification sound through all the speakers 9, so that the person in the dwelling unit can receive the visitor. Also, when the person in the household goes out,
When the switch 4 is switched to the going out terminal 4C and the destination telephone number is stored in the destination number setting circuit 5 before going out, the ring signal along with the visitor's ringing reads out the setting number entered in the destination number setting circuit 5 and transfers the number. 8, outside line 1
1 to call the telephone set at the set number.

On the other hand, the doorbell signal is branched into three systems and enters the destination number setting circuit 6, the synthesized sound generator 7, and the delay circuit 1o. is stored, and in response to the arrival of the doorbell signal, a message is read out and fed back to intercom 1, and the visitor in front of the intercom receives the message, for example, ``Please wait a moment while we connect you to your destination phone.'' ” can now be heard. The delay circuit 1o delays the incoming doorbell signal for at least a predetermined period sufficient for the end of the message, and then sends it to the switching circuit 12, thereby connecting the intercom 1 and the destination where the destination is being called by an outside line. Be able to talk to. This is to prevent the message from being mixed with the human voice from the destination telephone.

That is, a few seconds after the start of the message, a signal arrives at the switching circuit 12, and the number read out from the destination number setting circuit 6 becomes available for communication between the transfer destination via the central office line 11 and the intercom. .

Effects of the Invention As described above, in the present invention, when a visitor operates the doorbell using the intercom at the entrance, even if the person at home is not home, the person at home registers the external phone number of the destination in advance before going out. This is extremely advantageous in practical terms, as the doorbell performs a registered outside line calling operation, allowing a call to be made between the entrance and the destination.
