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. Also, Japanese Unexamined Patent Publication No.
As described in Japanese Patent Publication No. 82139, a thin electronic display panel is housed in an instrument panel in a substantially horizontal state, the electronic display panel has its screen facing upward, and the lower end of the electronic display panel is a housing part. The substrate is supported so as to be positioned on the front end side, is kept in a state of being considerably protruded from the stored state when used, and the substrate supporting the electronic display panel has a length twice or more that of the electronic display panel. Some are stored in the storage section.

[0003]

However, the dashboard of a vehicle is inconvenient because it cannot be installed with other audio equipment when a CRT television is installed in space. 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. Further, in the case of JP-A-61-282139, since the electronic display panel is used in a state in which it is considerably protruded from the housed state, it not only hinders the operation of the adjacent device, but also the substrate. Since it has a length more than twice that of the electronic display panel, the depth dimension of the storage section needs to be more than twice that of the electronic display panel, and miniaturization is desired.

The present invention has been made in view of the above circumstances, and can be incorporated in a dashboard of a vehicle leaving an installation space for other devices, and a TV can be installed at a position where an audio device is usually installed. It is also an object of the present invention to prevent the shift lever and the like from getting in the way, and further, to make it possible to reduce the size of the storage portion without requiring the depth dimension of the electronic display panel to be twice or more that of the electronic display panel.

[0005]

In order to achieve the above object, the present invention provides a thin display main body and a display main body which has the screen facing downward and is located below the screen. The casing includes a casing which is housed in a horizontal state in which the lower end of the casing is located at the back and is substantially horizontal, and a feed mechanism which moves the display main body into and out of the casing. A movable member provided movably with respect to the movable member, a slide member supporting the lower end portion of the display main body, and slidably provided on the movable member, and the slide member and the movable member in the casing. The display body is formed by a driving source that moves in and out, and the display body is configured such that the moving member moves out of the casing. When it is moved by the outside of a casing movement amount plus min, characterized in that the lower end is rotatably supported in the upward direction that rises from the horizontal state as an axis.

Further, the slide member is provided with a supporting member provided with a restricting portion for restricting further downward rotation of the display body from the horizontal state, and the display body is regulated in the horizontal state by the supporting member. It is characterized in that it is provided so as to move into the casing in a closed state.

Further, the moving member is formed by a rail extending from the front end of the casing to the innermost portion, and the rail is supported by the casing so as to move until it protrudes out of the casing, and the rail has the rail. A guide portion for movably guiding the slide member over the entire length is provided, and the slide member is provided so as to be movable from the outside of the casing to the innermost portion.

[0008]

When the display device of the present invention is incorporated in a dashboard of a vehicle, the display main body of the casing is in a substantially horizontal state when not in use, with its screen facing downward and the lower end being located in the inner part of the casing. It is stored inside, and when in use, the display body is sent out of the casing by the amount of movement that the moving member moved outside the casing, and the display body is erected at that position with the lower end side as the axis, To the front so that the shift lever does not get in the way even when the display device is attached to the position where the audio device is normally attached, and the position where the display body can be sufficiently erected while suppressing the depth dimension of the casing. It is possible to move up to.

Further, since the restricting portion for restricting the downward rotation of the display main body from the horizontal state is provided, when the display main body is housed in the casing, the display main body is guided by the stopper. It is possible to surely store it in the casing.

Further, the moving member is formed by a rail, and the rail moves until it projects to the outside of the casing, and the rail is provided with a guide portion for movably guiding the slide member over the entire length thereof. With a simple structure, it is possible to rotate the display main body in a direction in which it is sufficiently upright while suppressing the depth dimension of the casing.
