Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television mounted on a vehicle such as a dashboard of an automobile, and more particularly to a rotating mechanism for adjusting a screen display portion of the television to an arbitrary angle.

[0002]

2. Description of the Related Art Since a television for an automobile is installed in a limited space such as a dashboard, a thin television using a liquid crystal screen display unit has become popular. Also, some of the televisions have a screen display unit always held on the front surface of the device, and some of the televisions can be stored in the device except when in use. In both the holding type and the retracting type, it is necessary to adjust the angle of the screen display portion in the direction most easily seen when receiving an image.
For that reason, various angle adjusting mechanisms are incorporated. For example, there is one in which the screen display unit can be electrically adjusted in angle. In such a mechanism, the structure becomes complicated as the number of component parts increases, and the mechanism is incorporated into a device of a predetermined size. There may be restrictions on the combinations. Moreover, there is a possibility that the cost of the device will be high.

On the other hand, a holding-type television requires a considerably large installation area because of the size of the screen, and thus there is a problem that the installation space for other audio equipment is lost. Therefore, the television screen has a relatively large margin. There is a way to use the rear space. However, this method has a problem when a recording medium such as a cassette tape or a CD (compact disk) is inserted into an audio device, and it is necessary to temporarily move the television screen, which is a convenient device for realizing this. Is needed.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and in a vehicle-mounted television, a rotation mechanism of a television screen portion having a small and simple mechanism which can achieve space efficiency and cost reduction. The purpose is to provide.
