2. Description of the Related Art The installation of audio equipment such as a tape deck and a compact disk player on a dashboard of a vehicle has become widespread. In recent years, however, there has been a demand for the installation of a television, and it has been gradually spreading. . By the way, conventional on-vehicle televisions are of the cathode ray tube type, and although they are small, their outer dimensions are large, and a considerable installation space is required to install them.

[0003]

However, the dashboard in the vehicle cannot be mounted with other audio equipment when a CRT television is mounted in terms of space, and when mounted so that it can be seen from the passenger seat side, the dashboard is stopped. It was inconvenient because it could not be seen from the driver's seat side. Also, since the space where the audio equipment is mounted is relatively low on the dashboard, mounting the television at that position interferes with the shift lever and the like, making it difficult to see.

The present invention has been made in view of the above circumstances, and can be incorporated in a dashboard of a vehicle while leaving a space for installing other devices. A television can be used not only from a passenger seat but also from a stopped driver's seat. It is an object of the present invention to allow the user to watch the television and to prevent a shift lever or the like from being obstructed even when a television is attached to a position where an audio device is usually attached.

[0005]

In order to achieve the above object, the present invention provides a thin display body, a support mechanism for supporting the display body, a screen of the display body facing downward, and And a feed mechanism for moving the display body into and out of the casing. The feed mechanism is capable of rotating the display main body vertically rising from the horizontal state and moving the display main body to the outside of the casing rotatable in the left-right direction orthogonal to the upward direction, and the display main body. Is supported by the support mechanism so as to be rotatable in the left and right directions after being rotated in the upward direction, and assembled to a dashboard of a vehicle. When not in use, when not in use, the display body is stored in the casing with the display body being substantially horizontal, and in use, after the display body is sent out from the casing by the feed mechanism, the display body is erected, and the screen is directed forward, Further, when the vehicle is stopped, the vehicle can be seen from both the passenger seat and the driver seat. At that time,
Since the display main body is supported so as to be rotatable in an upward direction rising from a horizontal state around the lower end side of the display main body, the display main body is disposed at a relatively high position, and the shift lever and the like do not become an obstacle.
