  As described above, in the conventional panel drive device, generally, the disc insertion slot is exposed to the outside by tilting the opening / closing panel. However, the gap between the inner surface of the opening formed in the vehicle body side panel and the front outer peripheral surface of the opening / closing panel prevents the surface uniformity between the vehicle body side panel and the opening / closing panel from being impaired. Therefore, in the case where the outer periphery of the front panel of the open / close panel is extended outward and the outer dimensions are larger than the outer periphery of the front end of the chassis, the open / close panel is in an upright state and the front rear surface is in contact with the front surface of the chassis Therefore, the open / close panel cannot be tilted. For this reason, the conventional panel drive device has a problem that it is not possible to employ a technique for preventing a gap between the opening of the vehicle body side panel and the open / close panel.

  In this respect, Patent Document 1 avoids contact between the movable nose and the apparatus main body by rotating the movable nose in a standing state in parallel and then rotating the movable nose. However, since the cam hole and the guide hole for engaging the pin at the lower end of the arm are formed at a position higher than the chassis, the position of the arm has to be raised by this height, and the opening / closing panel is accordingly Therefore, the overall height of the apparatus main body could not be reduced.

  The present invention has been made to solve the above-described problems, and lowers the position of the arm to reduce the overall height of the apparatus, and at the time of opening and closing the open / close panel, which is a movable nose. It is an object of the present invention to obtain a panel drive device that can change the movement locus, facilitate the opening operation, and improve the adhesion of the open / close panel after the closing operation.

They are connected by the material 8 and formed in a U shape as a whole. Each drive member 7 is formed with a pin sliding path 9 composed of a long hole in the front-rear direction, and the front end portion of the pin sliding path 9 is bent in the left-right inward direction. Further, side plates 7 a are formed upright on the left and right outer sides of each drive member 7.

  A guide path 10 composed of a long hole in the front-rear direction is formed in the left and right front portions of the front portion of the chassis 6 on which the drive member 7 is slidably mounted. Both guide paths 10 are inclined obliquely outward in the left and right directions, and the front end portions of both guide paths 10 are bent in the left and right outer directions, and the rear end portions of both guide paths 10 are the front ends of the pin sliding paths 9. Is polymerized.

  A connecting member 11 is slidably held in the front-rear direction between the two drive members 7 and the chassis 6. The connecting members 11 are connected at their front ends by horizontal members 12 in the left-right direction. A long hole 13 in the left-right direction is formed at the rear end portion of the connecting member 11, and the left and right intermediate portions of both the long holes 13 overlap with the rear end portion of the guide path 10 and the front end portion of the pin sliding path 9. Yes. Further, side plates 14 are erected on the left and right outer sides of both connecting members 11.

  A connecting pin 15 is inserted into the overlapped portion of the left and right intermediate part of the long hole 13, the rear end part of the guide path 10 and the front end part of the pin sliding path 9. The connecting pin 15 includes a flanged shaft cylinder 15a through which the overlapping portion is inserted, a friction ring 15b fitted into the shaft cylinder 15a, and a screw 15c screwed into the shaft cylinder 15a.

  Between the side plate 7a of the drive member 7 and the side plate 14 of the connecting member 11, an auxiliary member 16 is disposed so as to be slidable in the front-rear direction. The auxiliary member 16 is formed in an I-shaped cross section having guide grooves 17 formed on both left and right (inside and outside) side surfaces, and a guide pin 7b projecting from the side plate 7a of the drive member 7 is formed in the left guide groove. Further, guide pins 30 protruding from the side plate 14 of the connecting member 11 are slidably fitted in the right guide groove, and a partition wall 16a is formed at an appropriate position of the left guide groove portion. Is formed. A guide pin 7b of the drive member 7 can come into contact with the partition wall 16a from the rear.

  In addition, an elastic body 31 is attached to the front end portion of the auxiliary member 16, and a receiving portion 31 a that supports the tilted opening / closing panel 3 from below is projected on the upper surface of the elastic body 31. Further, a tension spring 32 is provided between the rear end of the auxiliary member 16 and the rear side surface of the housing 2, and the auxiliary member 16 is urged rearward by the tension spring 32.

  One end portions of a pair of upper and lower first and second arms 18 and 19 are pivotally attached to shafts 18a and 19a on both left and right side surfaces of the open / close panel 3, respectively. Further, the other end of the first arm 18 is pivotally attached to the shaft 18 b of the side plate 14 of the connecting member 11, and the other end of the second arm 19 is fixed to the front end of the drive member 7. Has been. In addition, it is preferable to attach a torsion spring, a wave washer or a disc spring (not shown) to the other end of the first arm 18 and urge the first arm 18 upward. Thereby, the adhesiveness of the open / close panel 3 with respect to the front surface of the housing 2 is improved, and the backlash prevention of the open / close panel 3 is further improved. Further, by attaching the wave washer 18 a to one end of the first and second arms 18, 19, the backlash of the open / close panel 3 can be further prevented.

  Note that the rack 20 a and the pinion 20 b provided in the housing 2 are for advancing / retreating the driving member 7, and the rack 20 a is connected to one driving member 7. Also, forward and reverse power is applied to the pinion 20b meshing with the rack 20a through a power transmission system (not shown). A guide wheel 22 attached to the rear end of the driving member 7 is engaged with the front and rear grooves 21 formed on the left and right sides of the rear portion of the chassis 6 of the housing 2 so that the driving member 7 swings left and right. It can slide smoothly in the front-rear direction.

Next, the operation will be described.
When the operation button (not shown) provided on the front surface of the opening / closing panel 3 is switched on from the standing state of the opening / closing panel 3 shown in FIG. 4, the motor (not shown) is activated to drive the rack 20a and pinion 20b, thereby driving The member 7 moves forward. Then, as shown in FIGS. 7 to 9, the connecting pin 15 engaged and held at the front end portion of the pin sliding path 9 moves forward along the guide path 10 together with the drive member 7, and the connecting member 11 starts moving forward together with this. To do.

  Then, the first arm 18 connected to the connecting member 11 also starts moving forward. At the same time, since the second arm 19 fixed to the drive member 7 also starts to move forward, the open / close panel 3 also moves forward in parallel. By the way, since the guide path 10 that guides the connecting pin 15 is inclined obliquely outward as described above, the second arm 19 moves ahead of the first arm 18. For this reason, although the opening / closing panel 3 is slight, it is translated in a state where it is inclined backward.

  When the connecting pin 15 reaches the front end of the guide path 10 as shown in FIGS. 10 and 11, the connecting pin 15 is disengaged from the bent part of the pin sliding path 9 and the straight part of the pin sliding path 9 Move to. For this reason, as shown in FIG. 12 and FIG. 14, even if the driving member 7 continues to move forward, the connecting pin 15 does not move forward and remains stationary. In other words, the connecting pin 15 is retracted relative to the drive member 7. On the other hand, since the second arm 19 fixed to the drive member 7 continues to advance, the open / close panel 3 gradually tilts backward while moving forward. When the opening / closing panel 3 starts to tilt, the opening / closing panel 3 is separated from the front surface of the housing 2 to the front, and thus does not come into contact with the front surface of the housing 2.

  Then, as shown in FIGS. 15 and 16, when the driving member 7 moves forward, the connecting pin 15 relatively moves backward and reaches the rear end of the pin sliding path 9, and a sensor (not shown) detects this and shows it. Stop the motor. As a result, the rack 20a and the pinion 20b are stopped, so that the driving member 7 is also stopped. At this time, the open / close panel 3 is in a lying state, and the disc insertion slot 4 is exposed.

  On the other hand, when the drive member 7 moves forward by a predetermined distance, the guide pin 7b of the drive member 7 contacts the partition wall 16a of the auxiliary member 16 from the rear. As a result, the auxiliary member 16 starts moving forward together with the drive member 7 against the urging force of the tension spring 32. When the drive member 7 stops moving forward and the open / close panel 3 falls, the auxiliary member 16 has its front half projecting forward from the front surface of the housing 2, and the tilted open / close panel 3 is the front end of the auxiliary member. Is supported from below by the elastic body 31 attached to the.

  When the insertion or removal of the disc is completed, the motor (not shown) rotates in the reverse direction and the drive member 7 starts moving backward. At this time, since the auxiliary member 16 engaged with the guide pin 17b of the drive member 7 is urged backward by the tension spring 32, the backward movement of the drive member 7 at the start of the backward movement is assisted.

  As the drive member 7 moves backward, the open / close panel 3 follows the reverse operation. Briefly describing this, the open / close panel 3 gradually rises while moving backward, and the connecting pin 15 reaches the front end of the pin sliding path 9 to be engaged and held, whereby the connecting pin 15 is guided. When the movement starts along 10, the open / close panel 3 moves backward in the standing state. However, since the guide path 10 is inclined obliquely outward as described above, the guide path 10 is translated backward in a state where the upper end portion is slightly inclined by a movable locus preceding the lower end portion. For this reason, the upper end portion of the open / close panel 3 comes into contact with the front surface of the housing 2 before the lower end portion to which the driving force is applied. For this reason, the adhesion of the open / close panel 3 to the housing 2 is improved.

  As described above, according to the present invention, the guide path is provided on the bottom surface of the housing, and the connecting hole movable along the bottom surface of the housing and the bottom surface is provided with the elongated hole for the connecting pin. Since the end portion of the arm is configured to be attachable to the connecting member at substantially the same height as the bottom surface of the housing, the height of the first arm can be made lower than that of the conventional device. Has the effect of being feasible

  Further, according to the present invention, the guide path is disposed obliquely outside the opening / closing direction of the open / close panel so that the backward movement distance of the connecting member connected to the connecting pin is larger than the backward movement distance of the driving member. Since the opening / closing panel is configured to be inclined toward the front, the open / close panel moves parallelly forward with the lower end inclined as a movable trajectory preceding the upper end when opened, and the upper end precedes the lower end when closed. Since it moves backward in a state inclined by the movable track, there is an effect that the opening operation is smoothed and the adhesion of the opening / closing panel after the closing operation is improved.

  Further, according to the present invention, the forward and backward movement of the drive member is linked with a time lag to advance in the opening / closing direction of the open / close panel, thereby supporting the open / close panel tilted partly protruding forward from one side of the housing. Since the auxiliary member that can be configured is provided so as to be freely movable in the casing, there is an effect that the openable open / close panel can be supported stably and firmly.

  Further, according to the present invention, the spring member for biasing the auxiliary member backward is provided in the casing, and the auxiliary member moves backward when the drive member starts to move backward when the opening / closing panel is retracted in the closing direction. Since it is configured to be able to assist, there is an effect that the retracting operation of the opening / closing panel in the closing direction is performed stably and quickly.

  Further, according to the present invention, the elastic member that supports the open / close panel tilted when the auxiliary member protrudes from the front end portion of the housing is provided at the front end portion of the auxiliary member, so that it is in a lying state. The opening / closing panel can be received by an elastic body, and the opening / closing panel can be reliably supported without being damaged.
