On the outer surface of the pair of side arms 50, a pair of rollers 55 are rotatably supported at the front and rear corners, respectively, and a plate member 57 having a roller 56 is rotatably mounted around a shaft 57a. The plate member 57 is biased by a spring 58 in the clockwise direction in the drawing. These rollers 55,
56, the plate member 57 and the spring 58 are the side arms 50.
This is to prevent backlash, and its detailed function will be described later.

The mechanical base 40 includes the pair of pinion gears 43b and 43c shown in FIG.
(FIG. 5) It is inserted between the pair of side sliders 30 so as to be meshed with the pair of racks 21 a formed on the upper plate 21. By engaging the pinion gears 43b and 43c with the rack 21a, the mechanical base 40 is moved to the position shown in FIG.
It is movable with respect to the upper case 20 between the position of (a) and the position of FIG. 3 (c). The side arms 50 at both ends of the mechanical base 40 are arranged along the inner surfaces of the both side sliders 30, respectively, and the four rollers 55 of the side arms 50 are brought into contact with the upper and lower rails 38 of the side slider 30 as shown in FIG. .

Next, a mounting structure for mounting the display body 10 on the pair of side arms 50 will be described. As shown in FIGS. 12 and 13, metal mounting plates 14 are screwed on both side surfaces of the case 13 (made of resin) of the display main body 10, and the lower ends of the display main body are attached from the mounting plates 14. Mounting groove 13
b is formed. The mounting plate 14 has a plurality of through holes 141 communicating with a plurality of screw holes 13a formed in the case 13, and a positioning hole 1 communicating with the mounting groove 13b.
42 are formed. The positioning hole 142 is composed of a wide base end portion 142a and a narrow front end portion 142b, and the boundary portion thereof has a gentle curved surface. The mounting groove 13b of the case 13 has a tapered portion whose width becomes wider toward the end as shown in the figure.

On the other hand, a plurality of screw through holes 521 are formed in the display gears 52a and 52b provided at the tip of the side arm 50, and a large diameter and a small diameter are formed on the inner surface (the surface on the display body 10 side) thereof. The boss 52
2,523 are projected. The small-diameter boss 523 is provided at the center of rotation of the display gears 52a and 52b, and the large-diameter boss 522 is provided at a position eccentric from the center.
The diameter of the large-diameter boss 522 is the same as that of the base end portion 14 of the positioning hole 142.
The width of the small-diameter boss 521 is substantially the same as the width of 2a, and the diameter of the small-diameter boss 521 is substantially the same as the tip portion 142b of the positioning hole 142.

When mounting the display body 10,
The lower part of the display body 10 is provided with a pair of side arms 50.
Insert it in between. At that time, the bosses 522, 53 protruding from the display gears 52a, 52b of the both side arms 50 are provided.
The display body 10 is moved so that 3 passes through the mounting groove 13b of the display body 10. Since the tapered portion is formed at the tip of the mounting groove 13b, the bosses 522 and 523 can be easily inserted into the groove 13b, and the inserted bosses 522 and 523 can be inserted into the groove 1b.
It can be easily guided to the center side of 3b. Next, the bosses 522 and 523 move from the groove 13b to the positioning groove 142 of the mounting plate 14, and are engaged with the base end portion 142a and the tip end of the tip end portion 142b of the groove 142 as shown by the broken line in the figure. Since the tip end wall surface of the base end portion 142a has a gentle curved surface, the small diameter boss 523 can be easily guided to the groove tip end portion 142b.

When the bosses 522 and 523 are engaged with the groove 142, respectively, the display gear 52a,
The plurality of screw through holes 521 of 52b and the screw through holes 141 of the mounting plate 14 and the screw holes 13a of the case 13 are overlapped with each other and screwed through the screws BS respectively. As a result, the display body 1 is attached to the pair of side arms 50.
0 is attached, and the display body 10 can be rotated with respect to the side arm 50 by the rotation of the display gears 52a and 52b. The display device configured as described above is installed in the vehicle body by embedding the upper case 20 in the console portion.

Next, the operation of the display device will be described in detail. In the stored state shown in FIG. 1 and FIG. 3A, each side slider 30 is located at the rearmost position.
As shown in (a), each roller 33 falls into the notch 23d of the rail 23c by the biasing force of the spring 35 and presses the front and rear edge portions of the notch 23d. As a result, the side slider 30 is urged downward in the figure (upward when the vehicle is mounted) via the rollers 33, and the vertical direction play of the side slider 30 with respect to the upper case 20 due to vehicle vibration or the like occurs. To be prevented. At this time, the spring 37 is in the most loose state, but the backlash of the side slider 30 in the front-rear direction is also prevented by the roller 33 pressing the front-rear edge portion of the notch 23d.

On the other hand, as shown in FIG. 11 (a), the pair of side arms 50 are also located at the rearmost position, and the rollers 56
Is pressed against the rail 38 of the side slider 30 by the urging force of the spring 58. This allows the side arm 5
0 is biased upward in the drawing (downward in the vehicle mounted state) via the roller 56, so that the vertical play of the side arm 50 with respect to the side slider 30 is prevented.

When the open / close button BT is operated, the slide motor 41 (FIG. 7) is rotated in a predetermined direction, and the rotation is performed by the reduction gear mechanism 43 and the pinion gear 4.
3a is transmitted to the pinion gear 43b, and the pinion shaft 44 is used to transmit the pinion gear 43c.
Is also transmitted to Therefore, the pinion gears 43b, 4
The mechanical base 40, the side arm 50, and the display body 10 slide together in the direction A of FIG. 3 as the 3c moves on the rack 21a. At that time, FIG.
Each of the four rollers 55 shown in FIG.
Since it slides on the rail 38 of 0, each side arm 50
Can move smoothly. In addition, the roller 56 is a spring 85.
Since it rotates while being pressed against the rail 38 by the urging force of the side arm 50, the vertical movement of the side arm 50 is prevented even during the movement.

As shown in FIGS. 3B and 11B, when the tip ends of the pair of left and right side arms 50 substantially coincide with the tip ends of the side sliders 30, the left and right rollers 56 are urged by the spring 58. At the same time, it falls into the notch 38a of the rail 38 and is pressed by the front and rear edges of the notch 38a. Further, at this time, the roller 56 contacts the roller 55 at the lower end of the rear portion, and a load is applied to the rotation of both rollers 56, 55. This 2
Each side slider 30 is dragged by each side arm 50 by one action, and starts to move forward integrally. At that time, as shown in FIG. 6B, the rollers 33 of both side sliders 30 simultaneously run on the rails 23c from the notches 23d against the biasing force of the springs 35. In this way, the left and right rollers 56 drop into the notches 38a at the same time, and the left and right rollers 33 come out of the notches 32d at the same time, so that both side sliders 30 can start moving simultaneously without time shift. , Smooth movement is achieved.

Further, since the roller 33 rotates while pressing the rail 23c even after the roller 33 has escaped from the notch 23d, the vertical play of the side slider 30 is prevented even during the movement. Further, since the side slider 30 moves against the biasing force of the spring 37, the biasing force of the spring 37 also prevents the side slider 30 from rattling in the front-rear direction.

As shown in FIG. 3C, when the display main body 10 is completely projected from the console, the slide motor 41 is stopped and the tilt motor 42 is rotated in a predetermined direction. The rotation of the tilt motor 42 is performed by the reduction gear mechanism 47 (FIG. 7) and the pinion gear 51a, which are described above.
It is transmitted to the display gear 52a via the shaft 51b and the shaft 53 and the pinion gears 51c, 51.
It is transmitted to the display gear 52b via d, and both display gears 52a and 52b rotate in synchronization. As a result, the display main body 10 integrated with the display gears 52a and 52b rotates as shown in FIG. 4, and when reaching a predetermined position (a position where the screen can be visually recognized by the occupant), the tilt motor 42 is stopped. The display main body 10 is constantly biased in the rotational direction by the action of the torsion spring 54 externally attached to the shaft 53 in FIG. 7, so that the display main body 10 is prevented from rattling in the rotational direction. The front-rear position and the rotation position of the display body 10 can be appropriately adjusted by operating the operation member provided in the operation unit 12 to rotate the slide / tilt motors 41 and 42.

Since the load is applied to the spur gear 431 directly meshed with the slide motor 41 by the lock mechanism 45, the side arm 50, that is, the display main body 10 is moved in the vehicle front-rear direction when the vehicle body vibrates. Never move undesirably. On the other hand, when the occupant pushes the display body 10 with a force equal to or more than a predetermined value to adjust the front-back position of the display body 10, each spur gear 431 to
434 rotates while rotating the slide motor 41 against the load of the lock mechanism 45, which allows the display body 10 to move. At that time, spur gear 431
Will rotate while sliding on the felt 451 forming the lock mechanism 45.

Similarly, since a load is applied to the spur gear 431 directly meshed with the tilt motor 42 by the lock mechanism 48, the display body 1 is subject to vibration of the vehicle body.
0 does not rotate undesirably with respect to the side arm 50. Therefore, it is possible to hold the display body 10 at a desired position without bringing the back surface of the display body 10 into contact with the console. On the other hand, in order for the occupant to adjust the rotation position of the display body 10, a force greater than a predetermined value is applied to the display body 1
When trying to rotate 0, the spur gears 471 to 475 rotate while rotating the tilt motor 42 against the load of the lock mechanism 48, whereby the display body 10 is rotated.
Is allowed to rotate.

Also, for some reason, the display body 1
When a large external force in the front-rear direction of the vehicle (a force larger than the force that the occupant tries to push by hand) acts on 0, the gear 433b forming the torque limiter 46 rotates with respect to the gear 433a, which causes the display body 10 to move. The side arm 50 slides with the transmission of the rotational torque to the slide motor 41 cut off, and the display body 10 moves. Similarly, when a large external force in the rotating direction (a force larger than the force that the occupant attempts to rotate by hand) acts on the display body 10, the display body 10 causes the tilt motor 42 to move due to the action of the torque limiter described above. The display body 10 with the rotation torque transmission cut off
Rotates.

Open when the display device is in use /
When the close button BT is operated, the tilt motor 42
Is driven to rotate the display body 10 to the position indicated by the chain double-dashed line in FIG. 4, and then the slide motor 41 is driven to move the display body 10, the side arm 50, the mechanical base 40, and the side slider 30 to the position shown in FIG. From the state, slide and move in the B direction. When the state of FIG. 3B is reached, the rear end of the side slider 30 comes into contact with the rear plate 22 of the upper case 20 and its movement stops, and thereafter, only the display body 10, the side arm 50, and the mechanical base 40.

According to the first aspect of the present invention, the slider is biased upward or downward of the vehicle regardless of its sliding position. Therefore, during movement of the slider, that is, during projection or storage of the display device. Also, the vertical play of the slider can be prevented. In particular, since the pressing member for simultaneously moving the left and right sliders is also used as the mechanism for removing the vertical play of the sliders, the number of parts can be reduced, and the size and cost of the device can be reduced.
According to the third aspect of the present invention, the first slider is biased upward or downward of the vehicle regardless of its sliding position. Therefore, when the first slider is stopped, the first slider is also moved during the movement. Vertical play can be prevented. Further, since the pressing member for moving the second slider integrally with the first slider also serves as the backlash removing mechanism,
The number of parts can be reduced, and the size and cost of the device can be reduced.
