[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view schematically showing a state in which an outer box of a retractable panel device according to an embodiment of the present invention is partially cut away. In FIG. 1, a retractable panel device 10 includes:
An outer box 20 having a rectangular frame shape of standard 1 DIN size and having an opening in front (in the upper right direction in the figure) is provided.
The outer box 20 houses a panel unit 30 in which thin box-shaped individual cases are vertically stacked in two stages. The outer case 20 also houses a drive unit (drive mechanism) 40 that supports the rear end of the panel unit 30 and moves back and forth along the inner peripheral surface of the outer case 20.

The rectangular frame-shaped outer box 20 has a rack 21 extending in the front-rear direction on the ceiling surface, and a wide groove (not shown) extending in the front-rear direction on the inner peripheral surface of the side wall. On the other hand, the driving section 40 has a frame 41 having a U-shaped cross section which can be bent in the both ends of the strip extending in the width direction of the outer box 20 and accommodated in the outer box 20. A gear 42 meshing with the rack 21 is disposed on the upper surface of the center of the rack 41, and the entire bent portion at both ends is formed so as to enter a wide groove formed on the side wall of the outer box 20. A drive motor 43 is connected to the gear 42 via a speed reduction mechanism. When the frame 41 is accommodated in the outer case 20 while inserting the bent portions at both ends into the wide groove of the outer case 20, the drive motor 43 Gear 4 connected to 43
2 meshes with a rack 21 formed on the ceiling of the outer box 20. That is, the gear 42 and the rack 21 are held movably in the horizontal direction by the bent portion and the groove.
Thus, the power in the horizontal direction is actually transmitted. In this embodiment, the front-rear drive mechanism is configured as described above. Since it is only necessary to be able to move at least in the front-rear direction, the frame 41 has a shape substantially matching the inner peripheral wall of the outer box 20, and is slidable on the inner peripheral wall in the entire circumference so as to be movable in the horizontal direction. A normal driving mechanism that moves back and forth can be formed, for example, by contacting with a rubber tire and moving back and forth.

A backlight portion 31 of the panel portion 30 is rotatably supported on the upper end of the bent portion at both ends of the frame 41 via a rotation pin 44. The backlight unit 31 is connected to an upright motor 45 via a speed reduction mechanism provided near a support point on the left when viewed from the front. When the upright motor 45 rotates, the backlight unit 31 rotates about the rotation pin 44 with respect to the frame 41 via the speed reduction mechanism. This standing motor 4
5 and a speed reduction mechanism constitute a rotation drive mechanism. In the present embodiment, the backlight unit 31 is rotated by using the independent standing motor 45. However, a rack is partially formed on the ceiling surface of the outer box 20 and the speed reduction mechanism is used. The gear is exposed so that it can mesh with the rack, and when the frame 41 moves forward, when the two mesh with each other, the backlight unit 31 starts to rotate, and the independent standing motor 45 is not used. Can be. Needless to say, a similar operation can be performed in another configuration. The erecting motor 45 and the drive motor 43 are synchronized by electronic control, and the erecting motor 45 starts rotating when the drive motor 43 pushes the frame 41 to a predetermined position.

The frame 41 is provided with the backlight unit 31.
And the LCD panel 32 is held. Frame 4
A horizontal groove 46 is formed in the one bent portion, and a slide plate 47 is supported in this groove 46 via two pins so as to be able to move back and forth. On the other hand, the rear end of the LCD panel 32 is supported rotatably and slightly up and down with respect to the front end of the slide plate 47. LCD panel 32
Is supported by the frame 41 in this way, and as shown in FIGS.
1 is also slidably held in the front-rear direction.

FIG. 2 shows a state where the backlight unit 31 and the LCD panel 32 overlap each other from the front. As shown in FIG. A guide slit 31a that is bent in the vertical direction on the side is formed, and as shown in FIG. 4, an L-shaped guide protrusion 32a that can enter and engage with the guide slit 31a is formed on the LCD panel 32. . Since the guide slit 31a is formed up to the front end of the backlight portion 31, the rear end of the guide projection 32a is inserted from this front end and slid together to be combined. For example, a groove may be formed on the side surface of the backlight unit 31, and an arm may be formed on the LCD panel 32 side so as to sandwich the side surface of the backlight unit 31. Alternatively, another configuration may be used, such as forming a projection that enters the groove. When the LCD panel 32 and the backlight unit 31 are combined, the movable range of both is limited to a predetermined range.

As shown in FIG. 3, the backlight unit 31 contains a fluorescent tube 31b, so that a light-shielding material 31c made of non-woven fabric is provided around a surface that is in close contact with the LCD panel 32 so that light does not leak out. Is glued. As an alternative to the nonwoven fabric, for example, a light shielding material attached around the opening in the film case can be used. L
An arm 48 having the other end rotatably connected to the frame 41 is connected to a rear pin of the slide plate 47 on which the CD panel 32 is supported. Arm 4
Numeral 8 is coaxially held with a coil spring 49 at a connection portion with the frame 41. The coil spring 49 has one end in contact with the frame 41 and the other end in contact with the arm 48, and the arm 48 is moved to the frame. Biased in one direction. The urging direction is a direction in which the slide plate 47 is moved backward, and the LCD panel 32 is indirectly pulled backward.

Next, the operation of this embodiment having the above configuration will be described. FIG. 5 shows a state where the panel unit 30 is stored and a state where the panel unit 30 is erected when used. Initially, the drive unit 40 has moved to the back of the outer box 20. Also,
The arm 48 has its tip rotated with respect to the frame 41 to the left in the drawing, and at this position, the LCD panel 32 is pulled down most backward with respect to the backlight unit 31. When the operation unit (not shown) instructs the panel unit 30 to protrude, the drive motor 43 drives the gear 42 to rotate via the speed reduction mechanism. Gear 42 is outer box 2
0 and the frame 41 is engaged with the rack 21 in the front (see FIG. 5).
To the right). Initially, the relative position between the LCD panel 32 and the backlight unit 31 does not change. However,
When the backlight unit 31 reaches a position slightly before the entire backlight unit 31 is almost exhausted, the erecting motor 45 is started, and the backlight unit 31 starts rotating through the speed reduction mechanism. Then, along with this, the LCD panel 32 becomes the backlight unit 31.
Stand up with. Since the lower LCD panel 32 rotates around the support shaft of the upper backlight unit 31, LC
The support shaft of the D panel 32 is forced to move forward in a substantially circular arc with the support shaft of the backlight unit 31 as a center, and accordingly, the arm 48 rotates counterclockwise against the coil spring 49. I do. FIG. 6 shows a process in which both stand up. There is a difference in the rotation range between the rotation range necessary for the integral panel to rotate and the rotation range in which the thin panels are stacked in two stages as in this embodiment. Rotate in a smaller range. On the other hand, when storing
When the upright motor 45 rotates in the reverse direction and the backlight unit 31 is laid down, the arm 48 is moved through the slide plate 47 to the LCD.
In order to pull back the lower end of the panel 32, the LCD panel 32 is laid down and accommodated in the outer box 20, and before and after this, the drive motor 43 pulls the panel unit 30 together with the frame 41 into the outer box 20. Drive.

As described above, the thin box-shaped backlight portion 31
And the LCD panel 32 are accommodated in the outer case 20 in an overlapping manner, and the drive motor 43 of the driving unit 40
The frame 41 is moved forward and backward, and the panel unit 30 is moved forward and backward by meshing with the rack 21 and rotating. When the panel unit 30 is pushed forward, the erecting motor 45 rotates the upper backlight unit 31 so as to erect, so that the backlight unit 31 and the LCD panel 32 connected to each other rotate together. I do. Since the thin box-shaped backlight unit 31 and the LCD panel 32 rotate, the rotation range is reduced.

In the above-described embodiment, a non-woven fabric is attached as a light shielding material. However, a bellows-like material may be attached as shown in FIGS. Backlight unit 131 and LCD panel 13
A light-blocking bellows 133 is attached from the front end to the side surface of 2 to prevent light from leaking to the surroundings while allowing both to slide with each other. Further, in the above-described embodiment, the two individual cases are mechanically synchronized and driven using one drive motor and one stand-up motor. However, as shown in FIG. The motor 243 may be prepared for each individual case. For example, the upper individual case is the display 231, and the lower individual case is the operation panel 232. Initially, both are pushed out of the outer box 220 in a synchronized manner and stand up, and after the necessary operations are completed, only the operation panel 232 is stored asynchronously. When an operation is required, the operation panel 232 is pushed again to perform the operation.
Since the display and the operation panel 232 are arranged on different surfaces, the screen is enlarged, and the arrangement area of the switches and indicators is increased to facilitate the operation.
