[0002]

2. Description of the Related Art FIG. 11 is a plan view showing the structure of a conventional display device for a vehicle, and FIG. 12 is a right side view of FIG. The in-vehicle display device 1 is provided with a fixed case 2 attached to a console panel of the vehicle, and a pair of rack members 6 and 6 are fixed to a bottom 2b of the fixed case 2. In this fixed case 2, the intermediate case 3 is A
The intermediate case 3 is disposed so as to be movable in the 1-A2 direction.
When it moves in the direction A1, it protrudes forward from the nose portion 2c provided at the opening of the fixed case 2. A pair of rack members 8 are fixed to the bottom of the intermediate case 3 and inside the side walls. A moving bracket 5 is provided in the intermediate case 3 so as to be movable in the A1-A2 direction. A rotating shaft 9 having gears 7, 7 fixed at both ends is attached to the moving bracket 5, and the rotating shaft 9 is connected to a driving source 10 including a motor.
Is driven to rotate. The gears 7 fixed to the rotating shaft 9 mesh with the rack members 6 or 8. The television monitor 4 is rotatably supported by the movable bracket 5.
The television monitor 4 is rotated in a rising posture while the TV monitor 4 is moving forward in the A1 direction.

When the movable bracket 5 is housed in the intermediate case 3 and the intermediate case 3 is housed in the fixed case 2, the display device 1 uses a lock mechanism (not shown) to move the movable bracket 5 and the intermediate case 3. And are locked. At this time, when the gears 7, 7 are driven by the drive source 10, the gears 7, 7 mesh with the rack members 6, 6 in the fixed case 2, and the intermediate case 3 moves forward in the A1 direction. When the intermediate case 3 moves a predetermined distance in the direction A1, the lock by the lock mechanism is released at this time, and the moving bracket 5 is free with respect to the intermediate case 3, and the intermediate case 3 is moved with respect to the fixed case 2. Locked.

[0004] After that, the gears 7, 7 continue to be driven by the drive source 10, and only the moving bracket 5 moves alone in the A1 direction. During the forward movement of the moving bracket 5, the TV monitor 4 is started up and driven by a start-up mechanism (not shown) as shown in FIG. In FIG. 12, the horizontal posture before the television monitor 4 is started up and rotated is shown by (a), and the raised posture is shown by (b).

[0005]

When this type of in-vehicle display device 1 is installed on, for example, a console panel of an automobile, the installation space is restricted by the standard, and therefore, both side plates 2a and 2a of the fixed case 2 are limited. The width W1 between 2a and the width W2 of the intermediate case 3 are restricted. In the case of using the television monitor 4 having a relatively small size as shown by a solid line in FIG. 11, both side surfaces 4a, 4a of the television monitor 4 are used.
The gap between the inner case 3 and the side plates 3a of the intermediate case 3 can be sufficiently ensured, and there is room to arrange the rack member 8 and other support mechanisms in the gap between the two. However, in this apparatus, when a large-sized television monitor 4A as shown by a chain line in FIG.
The gaps between the b and 4b and the side plates 3a and 3a of the intermediate case 3 are very small, and the rack members 8 and 8 installed at the bottom of the intermediate case 3 and the side surfaces 4b and 4b of the television monitor 4A are vertically aligned. When the television monitor 4A rotates to the standing posture as shown in FIG. 12, the side surface 4b of the television monitor 4A and the rack member 8 interfere with each other, and the rotational operation of the television monitor 4A is hindered. was there.

In FIG. 11, a large television monitor 4 is shown.
In order to secure a gap between the side surface 4b of A and the side plate 3a of the intermediate case 3, it is conceivable to increase the width W2 of the intermediate case 3. However, if the width W2 is increased,
Side plates 3a, 3a of intermediate case 3 and side plates 2 of fixed case 2
The gap between a and 2a is too small. Therefore, not only the mechanism arranged inside the side plate 2a of the fixed case 2 is restricted, but also when mounting the fixed case 2 to a console panel or the like, the tip of the mounting screw screwed to the side plate 2a of the fixed case 2 However, a new problem arises in that it hits the side plate 3a of the intermediate case 3.

The present invention solves the above-mentioned conventional problem. In a device in which a display member is moved and a display member is started using a rack, the display member is made as large as possible. It is another object of the present invention to provide a display device capable of preventing the display member from interfering with the rack when the display member is started up.
