Description

Description: TECHNICAL FIELD The present invention relates to a door-phone subunit with a television camera, which is embedded in and attached to a wall of a house, such as a gatepost or entrance.

[Background Art] FIG. 5 shows a doorphone subunit of a conventional example, and this subunit is embedded in a wall of a gate, entrance, etc. of a house and attached, and is shown in FIG. As described above, the child device main body is embedded in the wall surface (a). Inside the slave unit,
An image pickup tube (b) such as a so-called vidicon for picking up an image of a visitor is arranged via an optical system (c), and a speaker (d), an electronic circuit section (e) such as a video circuit or a call circuit, etc. Is provided. On the front surface of the main body of the slave unit, a see-through window (F) for taking an image with the image pickup tube (B) through the optical system (C),
A push button (g) for calling is provided. The master unit that can communicate with the main unit of the slave unit is installed indoors, and the master unit can talk while watching the image of the visitor by the video signal and audio signal from the main unit of the slave unit. In such a conventional example, since the image pickup tube (b) is a tube type, it cannot be moved structurally, and is fixed integrally with the slave body. Therefore, the manufacturer specifies the mounting position, but it may not be mounted as specified due to the land and environment of each house. In addition, when it is installed in an existing house, the gate post is often lower than the designated position, and people may not enter the imaging range. Furthermore, construction cannot be performed due to the structure of the gate pillar and the entrance, and in many cases, the location where the slave unit main body is embedded is changed from the external appearance. In other words, since the image pickup tube (b) itself is also fixed, when changing the image pickup range, it is necessary to incline the entire slave unit, and in particular, the type in which the slave unit main body is embedded becomes unattractive in appearance. There was a problem.

[Object of the Invention] The present invention has been provided in view of the above points,
