DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail with reference to the accompanying drawings.

1 and 2 show a storage device for an image display device constructed according to the present invention. This device has a function as a monitor of a vehicle navigation system, for example, a fixed chassis 1 fixed to the upper surface of an instrument panel, a movable chassis 2 slidably mounted on the fixed chassis 1 so as to be movable back and forth, and fixed. A lid holding body 4a and a lid body 4b, which are pivotally attached at their rear ends to a left-right shaft 3 provided on the chassis 1, and a lid body 4
A liquid crystal panel 5 with a built-in backlight is housed inside b.

A longitudinal axis 6 is provided on one side of the fixed chassis 1 along a horizontal plane. A slide guide 7 fixed to one side of the movable chassis 2 is slidably fitted on the longitudinal shaft 6. Further, a compression coil spring 8 is contracted between the rear end of the front-rear direction shaft 6 and the rear end surface of the slide guide 7. On the other side of the fixed chassis 1, a guide groove 9 is extended in parallel with the front-rear direction shaft 6. Into this guide groove 9, a pin 10 protruding from the other side of the movable chassis 2 is inserted. The movable chassis 2 is slidable only in the front-rear direction by using the front-rear direction shaft 6, the slide guide 7, the guide groove 9, and the pin 10 as guide means.

The movable chassis 2 is equipped with an electric motor 14 which is connected to a rack 11 extending in the front-rear direction on the fixed chassis 1 through a reduction gear group 13 including a pinion 12. When the electric motor 14 is driven in the forward and reverse directions, the pinion 12 at the final stage of the reduction gear group 13 rotates, which rolls on the tooth surface of the rack 11 to move the movable chassis 2 back and forth. Further, the electric motor 14 and the reduction gear group 13
The first stage of the connecting portion with is composed of a worm speed reducer 15, and the movable chassis 2 is self-locked unless the electric motor 14 is started.

The liquid crystal panel 5 is supported at two substantially diagonal positions on its side surface, and one of the horizontal movement shafts 17 fixed to the movable chassis 2 is pivotally movable in a vertical plane. The other end is pivotally attached to the swivel movement shaft 16 fixed to the other end side of the lid holding body 4a whose one end is pivotally attached to the fixed chassis 1 side. These shafts 16.1
The positions of the liquid crystal display devices 7 are determined so that the turning movement shaft 16 is on the upper side and the horizontal movement shaft 17 is on the lower side when the liquid crystal panel 5 is horizontal.

In the non-use state, as shown in FIGS. 2 and 4, the liquid crystal panel 5 is in a state of lying down with its display surface facing downward, and the lid body 4b covers the back surface thereof. It is in a closed state. From this state, the electric motor 1
4 is driven to move the movable chassis 2 from the front to the rear of the vehicle body, as shown in FIGS. 3 and 5, the lid holding body 4a serves as a link member and its display surface faces the driver's seat side. Then, the liquid crystal panel 5 stands up while flipping up the lid body 4b. At this time, the elastic force of the compression coil spring 8 wound around the longitudinal shaft 6 assists the force for moving the movable chassis 2 backward.

When storing, if the electric motor 14 is driven in the opposite direction to the above, the movable chassis 2 moves forward, that is, toward the front windshield side, and the lid body 4b closes while the liquid crystal panel 5 falls down. At this time, when a certain angle is reached, the own weight of the lid body 4b and the liquid crystal panel 5 assists the force for moving the movable chassis 2 forward. Therefore, the output of the electric motor 14 can be set small by appropriately setting the spring constant of the compression coil spring 8 wound around the front-rear direction shaft 6.

FIG. 6 shows a second embodiment of the image display housing device according to the present invention. Also in this case, similarly to the first embodiment, the fixed chassis 21 fixed to the upper surface of the instrument panel 18 and the fixed chassis 2
The front-rear direction guide groove 2 recessed on the lower edge side of the inner surface of the side plate 1
2 is provided with a movable chassis 24 which is slidable only in the front-rear direction by engaging a pair of front and rear pins 23a and 23b.
The movable chassis 24 is also electrically driven by an appropriate drive device such as a rack / pinion type drive, as in the above. In the present embodiment, the fixed chassis 21 is almost completely embedded in the recess formed in the upper surface of the instrument panel 18, so that the amount of protrusion of the lid 25 covering the upper surface is minimized. Has been

A vertical slit 26 is provided on the front edge of the side plate of the movable chassis 24. This slit 2
A pin-shaped cam follower 29 protruding laterally is inserted into one end of a panel support plate 28 fixed to the side surface of the liquid crystal panel 27. The tip of this cam follower 29 is
It penetrates through the slit 26 and engages with a cam groove 30 provided in a side plate of the fixed chassis 21. The other end of the panel support plate 28 is pivotally attached to the other end of a link member 31 whose one end is pivotally attached to the fixed chassis 21.

Also in this configuration, since the movement locus of the other end of the panel support plate 28 is restricted by the link member 31 whose one end is pivotally attached to the fixed chassis 21, the movable chassis 24 from the stored state shown in FIG. When the vehicle is moved to the rear of the vehicle body (toward the driver's seat side), as shown in FIG.
The panel support plate 28 stands up while the 1 is being swung. Along with this, the liquid crystal panel 27 stands up with the display surface facing the driver's seat.

On the other hand, the cam groove 30 provided in the fixed chassis 21 is inclined upward as it goes rearward, and the cam follower 29 at one end of the panel support plate 28 is provided.
Is constrained by the vertical slit 26 of the movable chassis 24 and at the same time also constrained by the upwardly inclined cam groove 30, the liquid crystal panel 27 rises upright as the movable chassis 24 moves rearward. Go up. As a result, the display surface of the liquid crystal panel 27 can be exposed almost completely above the instrument panel 18.

In the case of this embodiment, the lid 25 is pivotally supported on the front edge side and is elastically urged in the closing direction by a torsion spring provided on the pivotal support portion, so that the liquid crystal panel 27 is Although it is closed in the laid-down state, when the liquid crystal panel 27 stands up, it is pushed up by the edge of the liquid crystal panel 27 and opened. The lid opening / closing mechanism is not limited to this, and the lid may be directly attached to the link member 31, for example.

[0019]

As described above, according to the present invention, the display surface faces downward during storage, and the lid covers the top surface of the instrument panel. Therefore, when a liquid crystal panel is used, the surface of the instrument panel exposed to sunlight is not exposed. It is possible to make the liquid crystal panel less susceptible to thermal influence. In addition, opening the lid simply by moving the movable chassis that slides on the guide rails and guide grooves using a rack / pinion mechanism, etc.
Since the closing operation and the upright / tilting operation of the display panel can be linked, the drive mechanism can be simple.
