Thus, as shown in FIGS. 1, 4, and 8, the display main body 31 can swing freely in the left-right direction B with respect to the movable tray 20 via the support shaft 36.

As shown in FIGS. 7A and 8, the bottom surface 31 a of the display main body 31, that is, the frame 3 having an elliptical frame shape is used.
The thickness L in the front-rear direction and the width H in the left-right direction of the support frame 35 that rotatably supports the bottom 32a of the second unit 32 via the support shaft 36 are the thickness L 'in the front-rear direction of the bottom surface 31a of the display main body 31 and the left-right direction. (L <L ', H <H'). As a result, as shown in FIG. 7B, the thickness L of the support frame 35 as the neck is reduced to the neck 7 of the conventional liquid crystal display 3.
(L <L).
L '). Further, the support frame 35 is attached to the display body 3.
1, the support shaft 36 is offset rearward from the bottom surface 31a of the display main body 31.

Further, as shown in FIGS. 2 and 3, a circular engagement hole 35b on one side wall of the support frame 35 has a hollow which is rotatably penetrated through the bush 26b of the other frame 25 of the movable tray 20. A cylindrical support shaft 39 is fitted and fixed, and the other side wall 35c of the support frame 35 is slidably penetrated by a bush 26a of one frame 25 of the movable tray 20 so as to be slidable. Of the support shaft 40 is fixedly projected. A gear 41 that meshes with the gear 27 driven by the motor 28 is fixed to the tip of the support shaft 40. A plurality of covered electric wires (routing material) for connecting the movable tray 20 and the display main body 31 are provided in a hollow cylindrical support shaft 36 for swinging and a hollow cylindrical support shaft 39 for tilt-up. ) 42 are penetrated and arranged. As a result, even if the color liquid crystal panel, the backlight, and the like of the display main body 31 become large, the display main body 31 is moved from the movable tray 20 through the plurality of covered electric wires 42.
A large amount of current, signal, etc. can be supplied to the side. The amount of rotation of the motor 28 is controlled by a pair of limit switches (not shown).

According to the hinge structure of the housing of the embodiment described above, when the movable tray 20 is pulled out from the opening 10a of the instrument panel 10 from the state shown in FIG.
The operation switch 17 of the instrument panel 10 is operated to drive the motor 15. When the motor 15 is driven, the movable tray 20 is moved through the pinion 13 and the rack 24.
Is drawn out from the opening 10a of the instrument panel 10 by a predetermined stroke in the horizontal direction, as shown in FIG.

When the operation switch 18 of the instrument panel 10 is operated to drive the motor 28,
As shown in FIG. 1, the liquid crystal display 30 rotates around the support shafts 39 and 40 via the gears 27 and 41 and rises. Further, the liquid crystal display 30 is manually swung about the support shaft 36 in the left-right direction B, and the liquid crystal display 3 is turned.
0 can be turned to a position where the screen 34 of the display main body 31 is easy to see. At this time, as shown in FIGS. 7A and 8, the thickness L in the front-rear direction and the width H in the left-right direction of the support frame 35 are set to the thickness L ′ in the front-rear direction of the bottom surface 31 a of the display main body 31 of the liquid crystal display 30. Formed so as to be smaller than the width H ′ in the left-right direction, and
The support frame 35 is attached to the back surface 31b of the display body 31.
And the support shaft 36 is offset rearward, so that when the display main body 31 of the liquid crystal display 30 is swung in the left-right direction, the upper surface of the support frame 35 is provided on the front side (front side) of the display main body 31 of the liquid crystal display 30. Is not exposed to the outside (the corner side). Therefore, when the display main body 31 of the liquid crystal display 30 is swung in the left and right direction, the front corner portion of the upper surface of the support frame 35 is not seen from the front side as shown in FIG. Appearance can be improved.

Further, a plurality of coatings are provided in a cylindrical support shaft 39 for rotatably supporting the display main body 31 of the liquid crystal display 30 with respect to the movable tray 20 and a cylindrical support shaft 36 for swingably supporting the display body 31. Since each of the electric wires 42 is penetrated, each of the coated electric wires 42 can be protected by the support shafts 36 and 39, respectively, and each of the coated electric wires 42 is not exposed to the outside. Thereby, when the display main body 31 is tilted, raised, and swung, each coated electric wire 4
Since 2 is not visible, the appearance of the display main body 31 of the liquid crystal display 30 can be further improved, and the degree of freedom in designing the appearance of the display main body 31 can be increased.

Further, since the display main body 31 can be swung in the left-right direction with respect to the movable tray 20 by the cylindrical support shaft 36, the display main body 31 can be easily adjusted to an easy-to-view angle. Since a plurality of covered electric wires 42 penetrate also into the cylindrical support shaft 36, the storage space for each covered electric wire 42 can be made as small as possible, and the whole structure is downsized and the components are simplified. be able to.

Further, as shown in FIG.
When the instrument panel 10 is stored in the storage section 11, the operation switch 22 b on the front end of the upper surface 20 a of the movable tray 20 is moved to the opening 10 of the instrument panel 10.
Since it is exposed outside from a, a switch operation other than the display function of the display main body 31 becomes possible, and the versatility can be further enhanced. At this time, the operation switch 22
b is the tapered surface 2 on the front end side of the upper surface 20a of the movable tray 20
0b, the operation switch 22b is easy to operate, and the operability is very good.

According to the above-described embodiment, the covered electric wire is used as the wiring member. However, an optical fiber or the like may be used as the wiring member. Also, the housing is not limited to a liquid crystal display, but a small T
Electrical components such as V may be used.

[0030]

As described above, according to the first aspect of the invention, the thickness of the neck in the front-rear direction and the width in the left-right direction are formed to be smaller than the bottom surface of the housing. Since it is arranged on the back side of the body and the other support shaft is offset backward, a part of the neck is not exposed to the outside and protrudes on the front side of the housing when swinging the housing in the left-right direction. Thus, the appearance of the housing can be improved.

According to the second aspect of the present invention, since the wiring members are respectively penetrated into the respective cylindrical support shafts which rotatably support the housing with respect to the support, the wiring members are respectively supported by the respective support shafts. And the routing material is not exposed to the outside. Thus, the wiring member cannot be seen when the housing is tilted or raised, so that the appearance of the housing can be further improved and the degree of freedom in designing the appearance of the housing can be increased.

According to the third aspect of the present invention, the liquid crystal display can be swung right and left by the other support shaft.
The liquid crystal display can be easily adjusted to an easy-to-view angle, and a part of the neck is not exposed and protrudes to the front side of the liquid crystal display when the liquid crystal display is swung.
