Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device, and more particularly, to a telephone number which is designated in advance by a calling signal from an intercom subunit or a camera-equipped intercom subunit to automatically call from outside the house. The present invention relates to a telephone device capable of dealing with visitors.

[0002]

2. Description of the Related Art In a conventional intercom system or intercom system with a camera, when a visitor is absent, a message (voice) from the visitor or a video of the visitor is recorded / recorded and then reproduced. There is a system that can be confirmed. As for the videophone with an answering machine, which is configured so that the sound / image from the intercom slave can be recorded as a reproduction possible later, as to the videophone with an answering machine, which is disclosed in Japanese Patent Laid-Open No. 5-137133, "A videophone with an answering machine and an answering machine with There is a method of responding to the calling subscriber by a video phone, and a method of responding to a visitor by a video phone with an answering machine. "

The one disclosed in this publication responds to a caller or a visitor by voice / image information from a telephone with an answering machine,
Also, in order to record voice and image information from callers and visitors, when there is an incoming call request to a videophone with an answering machine that is in answering machine mode, the request is automatically answered. In addition, the recording / playback section plays back to the calling subscriber as voice / image information indicating that the user is absent.
On the other hand, while being sent out, the message as a response from the calling subscriber can be recorded in the recording / playback unit as voice / image information so that it can be played back later. Also, when a call request is made from an intercom as a child device, the same measure is taken.

In Japanese Patent Laid-Open No. 3-6983, a start signal of the intercom master unit is output in order to output the image of the visitor by an image display device connected separately from the intercom device. To the terminal and the image signal output terminal, another video display device, for example, a videophone device or a television for receiving television broadcasting is connected,
The video of a visitor can be recognized even at a place away from the intercom system.
