Abstract

While a slide base (10) is pushing a panel (2) outward, a tab part (51) of an ejection bias spring (50) on a back end part of a leg part (10a) slides from a slide part (20a) of a slide guide member (8a) onto a convex contour(21a), becoming strongly deflected as a result, and biases the leg part (10a) to the inner side of a chassis (7), thereby correcting the G+ direction slanting of the panel (2) to the reverse direction. While the slide base (10) is drawing the panel (2) inward, a tab part (61) of an accommodation bias spring (60) disposed on a back end part of a leg part (10b) slides from a slide part (20b) of a slide guide member (8b) onto a convex contour (21b), becoming strongly deflected as a result, and biases the leg part (10b) to the inner side of the chassis (7), thereby correcting the slanting of the panel (2) to the G+ direction.

Description

Panel drive device

This invention relates to a panel drive device that reciprocates the lower end of the panel and opens and closes while rotating the panel.

As a mechanism for reciprocating the panel in the front-rear direction with respect to the main unit, for example, there is a front panel device for an in-vehicle electronic device described in Patent Document 1. The front panel device includes at least two cylindrical bodies provided at a predetermined interval in the front-rear direction of the main body device, a slide member provided with a long hole inserted into the cylindrical bodies, and both cylindrical shapes. Drive means for reciprocating the slide member in the front-rear direction of the main body device using the body and the long hole as guide means, a movable nose disposed on the front surface of the main body device, and lower portions on both sides of the movable nose on the tip side of the slide member It is a structure provided with the connection pin connected so that rotation is possible. Then, for the purpose of suppressing rattle noise of the slide member during the reciprocating movement of the front panel, a synthetic resin spacer having a thick portion is placed on the slide member, and a leaf spring placed on the spacer Both end portions of the spacer are fixed to the cylindrical body, and the thick portion of the spacer is pressed against the lower surface of the leaf spring between the cylindrical bodies.

Similarly, there is a liquid crystal display storage device described in Patent Document 2 as an example of suppressing rattle noise by reducing the backlash of the slide member. The liquid crystal display storage device is supported by a storage chassis, a first shaft pair fixed to both ends of the storage chassis, a guide support slidably mounted on the first shaft pair, and both ends of the guide support. A pair of shaft guides, a liquid crystal mounting portion on which a liquid crystal display is mounted, a table that rotatably supports the liquid crystal mounting portion at one end, and fixed to both ends of the table in parallel with the first shaft pair, and one end A second shaft pair slidably inserted into the shaft guide, and a drive mechanism for sliding the table along the second shaft pair via the first shaft pair, the shaft guide and the guide support. It is the composition provided. The table supporting the liquid crystal mounting portion is automatically slid along the second shaft pair supported by the storage chassis via the first shaft pair, the shaft guide and the guide support.

Japanese Patent Laid-Open No. 2004-210191 JP-A-5-153526

In the mechanism of Patent Document 1, the sliding resistance of the slide member is increased, but the clearance between the cylindrical body and the long hole is not lost, so the slide member can be tilted by this clearance. When the panel is reciprocated in the front-rear direction, the part engaged with the driving means on one side of the slide member advances first, and the other side follows to move forward, so that the panel is inclined by the clearance. Therefore, when the panel is fully opened, the panel is tilted in the left-right direction, and when the panel is fully closed, the gap between the panel and the design surface of the main unit is different in the left-right direction of the panel. There was a problem of losing.

Further, in the mechanism of Patent Document 1, since the thick part of the spacer is pressed against the lower surface of the leaf spring between the two cylindrical bodies, static friction works when starting to move from a stationary state, while it moves. Sometimes dynamic friction works. Then, since there is a large difference between the power at the start of movement and the power when moving, in order to obtain a predetermined sliding resistance for suppressing rattle noise, a driving force much larger than this predetermined sliding resistance is required. Some issues were necessary.

On the other hand, since the mechanism of Patent Document 2 requires members such as a table, first and second shaft pairs, a guide support, and a shaft guide, there is a problem that the mechanism is complicated and expensive.

The present invention has been made to solve the above-described problems, and it is an object of the present invention to make it difficult to cause the panel to tilt with a simple mechanism when the panel is stored and when the panel is fully opened.

The panel drive device of the present invention has a pair of legs disposed on the front surface of the main unit, and a pair of leg portions whose one end side is rotatably connected to both ends of the panel and the other end side extends in the back direction of the panel. A slide member having a rack formed on one of the parts, and being rotatably fixed to the main body device and meshing with the rack, receiving the driving force of the drive device to drive the slide member in the front-rear direction, and A pinion gear that opens and closes while rotating at the connecting portion, and is provided at a position behind the pinion gear regardless of the movement of the slide member in the front-rear direction, and urges the leg portion on which the rack is formed to the inside of the main unit. The panel push-out biasing spring and the leg that is located behind the pinion gear regardless of the movement of the slide member in the front-rear direction and the leg opposite the rack-formed leg Those comprising a panel housing biasing spring for biasing the inside.

According to the present invention, in the case where there is a guide play on the slide member by providing the panel push-out biasing spring and the panel storage biasing spring at a position behind the pinion gear regardless of the movement of the slide member in the front-rear direction. However, the panel push-out biasing spring stabilizes the slide member's posture when the panel is fully opened, and the panel storage biasing spring stabilizes the slide member's posture when the panel is stored. It is possible to make the inclination of the posture difficult to occur.

FIG. 4 is a perspective view of the main components of the panel drive device 1 as seen from the back side, in which one leg portion 10a of the slide base 10 and the slide guide member 8a are extracted and shown in FIG. A perspective view is shown in FIG. Moreover, the other leg part 10b and the slide guide member 8b of the slide base 10 seen from the back side of the panel 2 are extracted and shown in FIG.

A U-shaped slide base 10 having a pair of

legs

10a and 10b is provided on the back surface of the panel 2. Engagement holes are respectively formed at one ends of the

leg portions

10a and 10b, and are connected to protrusions formed at lower portions on both side surfaces of the panel 2 so as to be rotatable, thereby constituting

connection portions

13a and 13b.

Further,

bent portions

11a and 11b are provided on both outer sides of the

leg portions

10a and 10b. On the other hand, resin-made

slide guide members

8a and 8b are provided facing the outside of the

leg portions

10a and 10b. The

slide guide members

8a and 8b are fixed to the chassis 7, and

slide grooves

9a and 9b extending in the front-rear direction are formed on the inner surfaces of the

slide guide members

8a and 8b. Then, the

bending portions

11 a and 11 b are engaged with the

slide grooves

9 a and 9 b, whereby the slide base 10 is regulated in the height direction with respect to the chassis 7.

Also, a rack 14 is formed on the inner side of one leg 10a. The rack 14 meshes with a pinion gear 41 (shown in FIG. 8) that is rotatably attached to the chassis 7, and the pinion gear 41 is rotationally driven by a drive device (for example, a motor and a speed reduction mechanism) (not shown). Is moved back and forth.

Furthermore, a guide groove 12 extending in the front-rear direction is formed in the leg portion 10 a so as to be parallel to the rack 14. A slide base guide mechanism fixed to the chassis 7 side is engaged with the guide groove 12. The slide base guide mechanism is a mechanism that guides the slide base 10 in the front-rear direction. The slide base guide mechanism is a pair of guide pins 30a and 30b fixed to the chassis 7, and is inserted into the guide pins 30a and 30b and is rotatably attached. A pair of

collars

40a, 40b and a collar urging spring 31 that urges the

collars

40a, 40b toward the leg 10a are configured. The guide pins 30 a and 30 b are arranged at a predetermined interval in the moving direction of the slide base 10 and are fixed to the chassis 7. Holes at both ends of the collar urging spring 31 are inserted into the guide pins 30a and 30b, respectively, and

metal collars

40a and 40b rotate with respect to the guide pins 30a and 30b above the collar urging spring 31. It is attached freely.

The

metal collars

40a and 40b have a small cylindrical part 42 whose upper part is slightly smaller in diameter than the width of the guide groove 12 of the slide base 10, and a large cylindrical part 43 whose lower part is larger in diameter than the width of the guide groove 12; The small cylindrical portion 42 and the large cylindrical portion 43 are connected to each other, and a tapered portion 44 whose diameter increases toward the lower portion is formed. The

collars

40 a and 40 b are engaged with the guide groove 12 of the slide base 10 while being urged upward by a collar urging spring 31 fixed to the chassis 7.
The collar urging spring 31 urges the

collars

40a and 40b with a urging force that can absorb variations in height between the slide base 10 whose height is regulated by the

slide guide members

8a and 8b and the collars 40a and 40b. 10 is energized. Therefore, the slide base 10 can be moved only in the front-rear direction by the

slide grooves

9a, 9b of the

slide guide members

8a, 8b and the slide base guide mechanism.

Further, as shown in FIGS. 4 to 6, an extrusion biasing spring 50 having a tongue piece portion 51 for biasing the slide guide member 8a is fixed to the rear portion of the one leg portion 10a. A storage biasing spring 60 having a tongue piece 61 for biasing the slide guide member 8b is provided at the rear of the other leg 10b. Although the details will be described later, the push bias spring 50 and the storage bias spring 60 are disposed at a position behind the pinion gear 41 even when the slide base 10 moves in the front-rear direction.

On the other hand, at the position where the pushing biasing spring 50 faces in the slide guide member 8a, a sliding portion 20a with which the tongue piece 51 of the pushing biasing spring 50 abuts is provided. By making the convex portion 21a near the center of the sliding portion 20a and sliding the tongue piece portion 51 so as to ride on the convex shape 21a when the slide base 10 moves to the panel open position, the tongue piece portion Increase the degree of deflection of 51.
Further, as shown in FIG. 7, a sliding portion 20b with which the tongue piece portion 61 of the storage biasing spring 60 abuts is provided at a position where the storage biasing spring 60 faces in the slide guide member 8b. The rear part of this sliding part 20b is made into convex shape 21b, and when the slide base 10 moves to the position of the panel storage state, the tongue piece part 61 slides so as to ride on the convex shape 21b, whereby the tongue piece part 61 Increase the degree of deflection.

In this example, the sliding

guide members

8a and 8b are made of resin, and the push-out biasing spring 50 and the storage biasing spring 60 are made of metal. Thus, no abnormal noise and metal scrap are generated while the

tongue pieces

51, 61 slide on the sliding

portions

20a, 20b and the

convex shapes

21a, 21b.

As shown in FIGS. 1 to 4,

panel pins

34a and 34b are formed on the upper portions of both side surfaces of the panel 2, and

contact protrusions

35a and 35b are formed on both upper ends of the rear surface. On the other hand,

panel grooves

33a and 33b extending in the vertical direction are provided on both inner side surfaces of the panel storage portion 4, and convex rotation stoppers 36a and 36b are provided below the

panel grooves

33a and 33b. On the upper side, convex storage stoppers 37a and 37b are provided.

Panel pins

34a and 34b are slidably engaged with the

panel grooves

33a and 33b.
It should be noted that the rotation stopper 36a and the storage stopper 37a are not shown because they are hidden and cannot be seen on the drawing.

In the panel storage state shown in FIG. 3, the slide base 10 is retracted and stored in the chassis 7, and the panel pins 34 a and 34 b of the panel 2 are located at the upper ends of the

panel grooves

33 a and 33 b, and come into contact with the projections. The

portions

35a and 35b are in contact with the storage stoppers 37a and 37b. When the slide base 10 is advanced from this state, the lower connecting

portions

13a and 13b of the panel 2 advance, while the upper panel pins 34a and 34b move downward along the

panel grooves

33a and 33b. It rotates around the connecting

portions

13a and 13b. As shown in FIG. 2, when the panel 2 is completely rotated, the

contact protrusions

35 a and 35 b of the panel 2 come into contact with the rotation stoppers 36 a and 36 b of the panel storage unit 4, and the rotation stops. At the same time, the forward movement of the slide base 10 is also stopped. This state is the panel open state.

Next, the operation of the panel drive device 1 as described above will be described.
8 to 13 show the operation of the panel driving device 1, FIG. 8 is a panel storage state, FIG. 9 is a state in the middle of opening the panel 2, FIG. 10 is a state immediately before the panel 2 is fully opened, and FIG. FIG. 12 shows a state in which the panel 2 is being accommodated, and FIG. 13 shows a state immediately before the panel 2 is completely accommodated. For convenience of explanation, in FIGS. 8 to 13, illustration of the top surface of the panel storage unit 4 and the chassis 7 is omitted, and the inside of the main unit 3 is exposed.

In the panel storage state in which the panel 2 is stored in the panel storage portion 4, as shown in FIG. 8, the tongue piece portion 51 of the pushing biasing spring 50 is slightly bent and contacts the sliding portion 20a of the slide guide member 8a. Make contact. Since the tongue piece 61 of the other storage urging spring 60 is in contact with the convex shape 21b of the sliding portion 20b of the slide guide member 8b, it is pressed by the convex shape 21b and is strongly bent. Further, since the storage biasing spring 60 biases the slide base 10 toward the inside of the chassis 7, the

collars

40 a and 40 b are in a state of being close to one side of the guide groove 12.

In order to push the panel 2 forward and open it from the panel storage state as shown in FIGS. 3 and 8, the pinion gear 41 is rotated in the direction of the arrow by a driving device (not shown), and the rack 14 engaged therewith is pushed forward. . At this time, the

collars

40a and 40b approaching one side of the guide groove 12 rotate and guide the forward movement of the slide base 10, but due to the backlash between the guide groove 12 of the slide base 10 and the

collars

40a and 40b, Since the leg portion 10a on the rack 14 side advances slightly ahead of the other leg portion 10b, the panel 2 moves forward in a state inclined in the G + direction as shown in FIG.

When the slide base 10 further advances in the panel opening direction, as shown in FIG. 10, the tongue piece 51 of the pushing biasing spring 50 fixed to the slide base 10 slides from a position before the panel 2 is fully opened. It slides so as to ride on the convex shape 21a of the sliding portion 20a of the guide member 8a. The tongue piece 51 slides in contact with the sliding portion 20a while being slightly bent, but further biases at the portion of the convex shape 21a to urge the slide base 10 in the F1 direction. By this energization, the panel 2 is rotated while being forced in the G− direction from the state inclined in the G + direction as shown in FIG. 10, and then the panel 2 provided at the upper back of the panel 2 as shown in FIG. 2. The

contact projections

35a and 35b come into contact with the rotation stoppers 36a and 36b provided in the panel storage portion 4, and the rotation of the panel 2 is completed, so that the panel opened state shown in FIGS. .

In the panel pushing operation described above, the pushing biasing spring 50 stabilizes the posture of the slide base 10 even if there is an engagement play of the guide groove 12 (the guide play of the slide base 10), so that the posture of the panel 2 is inclined when the panel is open. Can be made difficult.
Further, since the tongue piece 51 of the pushing biasing spring 50 is slightly bent even when the panel is housed, the impact when contacting the convex shape 21a of the slide guide member 8a is eliminated, and vibration and noise are prevented. be able to.
Further, since the start of the convex shape 21a is a gentle taper shape, the correction of the panel 2 in the G-direction can be performed gently, so that a panel pushing operation without a sense of incongruity can be performed.
Further, as shown in FIG. 8, the convex shape 21 a and the convex shape 21 b are arranged so as not to overlap each other when viewed from both ends of the panel 2. Neither of the biasing springs 60 has the maximum biasing force, and the sliding resistance during the panel pushing operation can be reduced.

Next, the case where the panel 2 is stored from the fully opened state (FIG. 11) will be described. The rack 14 engaged with the rack 14 is rotated by rotating the pinion gear 41 in the opposite direction to the pushing operation of the panel 2 by a driving device (not shown). Pull back, that is, into the main unit 3. At this time, due to the backlash between the guide groove 12 of the slide base 10 and the

collars

40a and 40b, the leg 10a on the rack 14 side advances slightly ahead of the other leg 10b. As shown in FIG. 2, the wire is pulled in the G-direction.

When the slide base 10 further advances in the panel closing direction, the tongue piece 61 of the storage urging spring 60 fixed to the slide base 10 slides from a position before the panel 2 is completely closed as shown in FIG. It slides so as to ride on the convex shape 21b of the sliding portion 20b of the guide member 8b. The tongue piece 61 slides in contact with the sliding portion 20b while being slightly bent, but further biases at the portion of the convex shape 21b to urge the slide base 10 in the F2 direction. By this urging, the panel 2 is rotated while being forced in the G + direction from the state inclined in the G− direction as shown in FIG. 13, and then the panel 2 provided on the upper back of the panel 2 as shown in FIG. 3. The

contact projections

35a and 35b come into contact with the storage stoppers 37a and 37b provided in the panel storage unit 4, and the storage of the panel 2 is completed, and the panel storage state shown in FIGS.

In the above-described panel storing operation, the storing biasing spring 60 stabilizes the posture of the slide base 10 even if there is a backlash of the guide groove 12, so that it is difficult for the panel 2 to tilt in the panel storing state. For this reason, the clearance gap between the panel 2 and the panel accommodating part 4 (it becomes a design surface) becomes comparable at the right and left of the panel 2, and a high-class feeling is not impaired.
Further, since the tongue piece 61 of the storage urging spring 60 is slightly bent even when the panel is open, the impact when contacting the convex shape 21b of the slide guide member 8b is eliminated, and vibration and noise are prevented. be able to.
Further, since the start of the convex shape 21b is a gentle taper shape, the correction of the panel 2 in the G + direction can be performed gently, so that a panel storing operation without a sense of incongruity can be performed.
Further, as described above, at the intermediate position A (FIG. 8) where the convex shape 21a and the convex shape 21b do not overlap with each other, neither the pushing biasing spring 50 nor the housing biasing spring 60 has the maximum biasing force, and the panel is housed. Sliding resistance during operation can be reduced.

As described above, even when the tongue piece 51 of the push biasing spring 50 is not in contact with the convex shape 21a of the slide guide member 8a (FIGS. 8, 9, and 13), The sliding base 10 is bent to such an extent that sliding resistance is obtained.
In a conventional friction mechanism in which a leaf spring is pressed against a slide member via a spacer as described in Patent Document 1 described in advance, the static friction is caused by a large difference in the friction coefficient between static friction and operation friction. The difference between the driving force for moving the slide member from the state and the driving force during operation is large. Therefore, when the conventional configuration is applied to the panel driving device 1, an excessive driving force is required to move the panel 2, and expensive parts such as a high output motor is used as a driving device (not shown). It becomes.

On the other hand, in the first embodiment, by using a friction mechanism using a pair of

collars

40a and 40b, the parts that receive the urging force of the pushing urging spring 50 become

rotatable collars

40a and 40b. The friction generated between 40b and the guide groove 12 becomes rolling friction. Accordingly, the amount of change between the driving force for moving the slide base 10 from the stationary state and the driving force during operation is reduced, and it is not necessary to employ a high output motor as a driving device for moving the panel 2, and an inexpensive panel. The drive device 1 can be realized.
Further, since the

metal collars

40a and 40b and the guide groove 12 of the slide base 10 are always moved to one side by the urging force of the pushing urging spring 50, the gap between the

collars

40a and 40b and the guide groove 12 and the collar The gap between 40a, 40b and guide

pins

30a, 30b is eliminated, and rattle noise due to vibration is eliminated.

Furthermore, a tongue piece 52 for chassis ground may be formed on the pushing biasing spring 50 so that the tongue piece 52 is grounded to the chassis 7 and sliding resistance is obtained. In addition to the tongue piece 52 or in place of the tongue piece 52, a chassis earth tongue 62 is formed on the storage biasing spring 60, and the tongue 62 is grounded to the chassis 7 and slid. Dynamic resistance may be obtained.

As described above, according to the first embodiment, the panel drive device 1 is connected to the panel 2 disposed on the front surface of the main body device 3 and one end side is connected to both ends of the panel 2 with the connecting

portions

13a and 13b, The other end side has a pair of

legs

10a and 10b extending in the back direction of the panel 2, and a slide base 10 having a rack 14 formed on one leg 10a and a main body device 3 are rotatably fixed to the rack 14. The rack 14 is formed with a pinion gear 41 and a rack 14 that are engaged and driven by a driving device (not shown) to drive the slide base 10 in the front-rear direction and rotate the panel 2 by the connecting

portions

13a and 13b. Regardless of the movement of the slide base 10 in the front-rear direction, the leg 10a is fixed at a position behind the pinion gear 41, and urges the slide base 10 to the inside of the main body device 3. The protruding biasing spring 50 and the leg portion 10b opposite to the leg portion 10a on which the rack 14 is formed are fixed at a position behind the pinion gear 41 regardless of the movement of the slide base 10 in the front-rear direction. A storage biasing spring 60 that biases the slide base 10 toward the inside of the main body device 3 is provided. Therefore, even when the slide base 10 has guide backlash, the pushing biasing spring 50 stabilizes the posture of the slide base 10 when the panel 2 is fully opened, and the housing biasing spring when the panel 2 is fully stowed. 60 can stabilize the posture of the slide base 10. Therefore, it is possible to make it difficult to cause the inclination of the posture when the panel 2 is stationary with a simple mechanism. Further, in the state in which the panel 2 is fully stored, the gap with the design surface is the same on the left and right sides of the panel, so that the sense of quality is not impaired.

Further, according to the first embodiment, the panel driving device 1 is fixed to the main body device 3, and the sliding

portions

20a and 20b are formed that move while the pushing biasing spring 50 and the storage biasing spring 60 are in contact with each other. One sliding portion 20a having a pair of

slide guide members

8a and 8b, with which the pushing biasing spring 50 abuts, has a convex shape 21a that presses the pushing biasing spring 50 while the slide base 10 moves forward. The other sliding portion 20b with which the storage biasing spring 60 abuts is configured to have a convex shape 21b when the storage biasing spring 60 is pressed while the slide base 10 moves backward. For this reason, during the panel pushing-out operation and the storing operation, the pushing biasing spring 50 and the storing biasing spring 60 slide on the sliding

portions

20a and 20b of the

slide guide members

8a and 8b, so that stable sliding is achieved. Resistance can be obtained. In addition, since the pushing biasing spring 50 is strongly bent from the position before the panel 2 is fully opened and the maximum biasing force is applied, the panel 2 is not tilted in the fully opened state. Further, since the storage biasing spring 60 is strongly bent from the position before the panel 2 can be fully stored and the maximum biasing force works, the panel 2 does not tilt in the stored state.

Further, according to the first embodiment, the panel drive device 1 includes a pair of slide bases 10 and

slide grooves

9 a and 9 b formed in a pair of resin-made

slide guide members

8 a and 8 b, and

convex shapes

21 a and 21 b, respectively. A pair of

bent portions

11a and 11b that are formed on both outer sides of the

leg portions

10a and 10b and engage with the

slide grooves

9a and 9b. Further, an extrusion biasing spring 50 is attached to the leg portion 10a. The storage biasing spring 60 is attached to the portion 10b. Therefore, the pushing urging spring 50 and the storage urging spring 60 slidably move the sliding

portions

20a and 20b and the

convex shapes

21a and 21b while the

bent portions

11a and 11b and the

slide grooves

9a and 9b are engaged to regulate the height. The rattle noise can be reliably suppressed while obtaining a stable sliding resistance.

Further, according to the first embodiment, the

convex shapes

21a and 21b formed on the pair of

slide guide members

8a and 8b are arranged at positions where they do not overlap each other when viewed from both ends of the panel 2. For this reason, during the movement of the slide base 10 in the front-rear direction, at the intermediate position A where the

convex shapes

21a and 21b do not overlap, neither the pushing biasing spring 50 nor the storage biasing spring 60 is operated with the maximum biasing force. The sliding resistance inside can be reduced.

Further, according to the first embodiment, the panel driving device 1 is fixed to the main body device 3 and is provided with a pair of guide pins 30a and 30b arranged at predetermined intervals along the moving direction of the slide base 10, and the guide pins 30a. , 30b, a pair of

collars

40a, 40b rotatably attached to each, and a guide groove 12 formed in parallel to the rack 14 on the leg portion 10a of the slide base 10 and loosely fitting the pair of

collars

40a, 40b. It was configured as follows. For this reason, the friction generated between the guide groove 12 of the slide base 10 and the

collars

40a and 40b becomes rolling friction, and the difference between the driving force at the start of the operation of the slide base 10 and the driving force during the operation can be reduced. A high output driving device (not shown) is not required. Therefore, an inexpensive panel driving device 1 can be realized.

The panel driving device 1 according to the first embodiment is only required to be able to bias the slide base 10 toward the inside of the chassis 7 by the biasing force of the push biasing spring 50 and the storage biasing spring 60. A configuration in which the positions of the spring 50 and the storage biasing spring 60 and the positions of the sliding

portions

20a and 20b are reversed may be employed. Specifically, the push biasing spring 50 and the storage biasing spring 60 are fixed on the

slide guide members

8a and 8b of the chassis 7 so that the side surface (which becomes a sliding portion) of the slide base 10 slides. To do. Even in this configuration or the configuration of the first embodiment, the position where the push biasing spring 50 and the storage biasing spring 60 are provided is the pinion gear regardless of the movement of the slide base 10 in the front-rear direction. The point that is the position behind 41 does not change.

In addition to the above, within the scope of the present invention, the present invention can be modified with any constituent element of the embodiment or omitted with any constituent element of the embodiment.

As described above, in the panel drive device according to the present invention, the biasing spring is provided at the rear end portion of the slide member, and the slide member is biased inward of the main body device to correct the inclination of the panel caused by the guide play. Since it did in this way, it is suitable for using for the panel drive apparatus of information apparatuses, such as a navigation apparatus and an audio apparatus which open and close, rotating a lower end part of a panel.
