  By the way, in the configuration as described in Patent Document 1, the recording / reproducing means is fixed to the chassis. For this reason, when the information recorded on the disk is processed by the recording / reproducing means, the disk vibrates due to the rotational vibration of the rotation of the disk, which may hinder reading or recording of information.

The stop member holds the guide member 723 at a predetermined height position of the main shaft 722 and prevents the guide member 723 from falling off. Further, the peripheral portion of the guide member 723 functions as a leaf spring by this stop member, and the sliding contact portion 728A is urged toward the cylindrical portion 725 side. As a result, when the drive gear 721 rotates, the guide member 723 also rotates in the same direction as the rotation direction of the drive gear 721 due to friction between the sliding contact portion 728A and the cylindrical portion 725.

  A driving force transmission mechanism 730 that transmits the driving force of the motor 710 to the driving gear portion 720 is provided between the motor 710 and the driving gear portion 720 of the driving base portion 701.

It is attached so as to be rotatable with respect to the shaft center.

  The rotation switching plate 734 is a flat plate member having one end portion rotatably attached to the shaft of the second drive transmission gear 732 and having a longitudinal direction. Further, when the second drive transmission gear 732 rotates clockwise, the rotation switching plate 734 receives a biasing force clockwise by this rotational frictional force and rotates clockwise. On the other hand, when the second drive transmission gear 732 rotates counterclockwise, it receives a biasing force counterclockwise by this rotational frictional force and rotates counterclockwise.

  An engagement pin 735 that protrudes on the lower surface side is attached to the other end of the rotation switching plate 734. Further, the third drive transmission gear 733 meshed with the second drive transmission gear 732 is freely rotatable between the position where the shaft of the second drive transmission gear 732 of the rotation switching plate 734 is attached and the engagement pin 735.

It is held at the same height. Furthermore, a part of the rotation switching plate 734 is formed wide, and an arcuate guide groove 736 centering on the axis of the second drive transmission gear 732 is formed in the wide portion. The guide groove 736 is engaged with a rotation restricting pin 736 </ b> A that is erected on the drive base 701. Thereby, the rotation range of the rotation switching plate 734 is restricted within a range in which the rotation restriction pin 736A is engaged with the guide groove 736.

  Here, when the second drive transmission gear 732 is rotated counterclockwise by the driving force of the motor 710 as viewed from above, the rotation switching plate 734 is also rotated by the rotational frictional force of the second drive transmission gear 732 as described above. It is rotated counterclockwise. At this time, the third drive transmission gear 733 meshed with the second drive transmission gear 732 is meshed with the drive gear 721 and transmits the driving force of the motor 710 transmitted from the second drive transmission gear 732 to the drive gear 721. . The engaging pin 735 is engaged with the notch 727 of the guide member 723 and is disposed close to or in contact with the cylindrical portion 725 on the upper surface side of the drive gear 721. Further, even if the restriction wall 724 is rotated to a position facing the engagement pin 735 by the rotation of the drive gear 721, the engagement pin 735 passes through the groove between the restriction wall 724 and the cylindrical part 725. The rotation of the restriction wall 724 is not hindered.

  When the second drive transmission gear 732 is rotated clockwise as viewed from the upper surface side by the driving force of the motor 710, the rotation switching plate 734 also receives a clockwise rotational frictional force. At this time, when the restriction wall 724 is located on the upper surface of the drive gear 721 in the direction from the main shaft 722 to the engagement pin 735, that is, when the opening of the notch 727 is closed by the restriction wall 724.

[Disk unit operation]
Next, the operation of the disk device 100 will be described with reference to the drawings.

(Drive switching operation of drive gear and gear pedestal drive)
First, the drive switching operation of the drive gear unit 720 and the gear base drive unit 740 in the operation of the drive unit 700 of the disk device 100 will be described with reference to FIGS. FIG. 13 is a plan view showing one state of the drive unit 700 when the motor 710 is rotated forward. FIG. 14 is a plan view showing one state of drive unit 700 when motor 710 is further rotated in FIG. FIG. 15 is a plan view showing another state of drive unit 700 when motor 710 is further rotated in FIG. FIG. 16 is a plan view showing a state of drive unit 700 when motor 710 is further rotated in FIG. FIG. 17 is a plan view showing a state of drive unit 700 when motor 710 is further rotated in FIG.

  The drive unit 700 rotates forward or reversely under the control of a control circuit unit (not shown), and rotates the motor task gear 711 in a predetermined direction. Then, when the motor task gear 711 is rotated forward by the motor 710, the first drive transmission gear 731 and the third drive transmission gear 733 rotate clockwise (indicated by arrows in FIG. 13) when viewed from the upper surface side, The drive transmission gear 732 is rotated counterclockwise when viewed from the upper surface side. Further, the rotation switching plate 734 receives a rotational frictional force clockwise by the rotation of the second drive transmission gear 732. Further, due to the rotation of the rotation switching plate 734, the engagement pin 735 moves toward the drive gear portion 720 side and is engaged with the notch portion 727. As a result, the third drive transmission gear 733 is engaged with the drive gear 721 and rotates the drive gear 721 counterclockwise.

  In this state, when the motor task gear 711 is further rotated in the forward direction, the sliding contact portion 728A of the rotation assisting piece 728 is also in sliding contact with the column portion 725 of the drive gear 721. It rotates counterclockwise by force. Thereafter, the guide member 723 stops at a position where the engagement pin 735 contacts the end portion of the cutout portion 727 where the regulation arc portion 727A is not provided. As described above, in a state where the engagement pin 735 is engaged with the notch 727, when the motor task gear 711 is rotated forward by the motor 710, the drive gear 721 rotates counterclockwise.

  Then, when a signal to change the transmission destination of the driving force is output from the transport unit 340 to the retraction control mechanism 420 or the movement control unit 540, for example, a sensor (not shown) of the driving unit 700 causes the driving gear 721 to move. The positions of the restriction wall portion 724, the restriction arc portion 727A of the guide member 723, and the engagement pin 735 are detected and output to the control circuit portion as appropriate. Then, when it is detected by the sensor that the notch 727 is opened, the control circuit unit reverses the driving rotation direction of the motor 710 as shown in FIG. On the other hand, when it is detected by the sensor that the restriction wall portion 724 is located in the radial direction from the axis of the drive gear 721 toward the engagement pin 735 and the notch portion 727 is closed by the restriction wall portion 724, The control circuit unit rotates the motor 710 in the normal direction to rotate the drive gear 721 counterclockwise by a predetermined angle, so that the notch 727 is opened. In this state, when the drive rotation direction of the motor 710 is reversed, the second drive transmission gear 732 of the drive force transmission mechanism 730 is rotated clockwise, so that the rotation switching plate 734 is rotated by the rotational friction of the second drive transmission gear 732. Turns clockwise in response to force. The third drive transmission gear 733 is engaged with the gear pedestal drive gear 741, and the driving force of the motor 710 is transmitted to the gear pedestal drive unit 740.

  On the other hand, when the rotation of the drive gear 721 needs to be reversed, for example, when the movement direction of the movement control unit 540 is reversed, the control circuit unit uses a sensor to control the restriction wall 724 and the notch 727. And the position of the engaging pin 735 are detected. In the control circuit unit, the restriction wall 724 is positioned in the radial direction from the axis of the drive gear 721 toward the engagement pin 735 by the sensor, and the notch 727 is closed by the restriction wall 724. When detected, as shown in FIG. 16, the driving rotation direction of the motor 710 is reversed. When the sensor detects that the notch 727 is opened by the sensor, the control circuit unit rotates the motor 710 in the normal direction and rotates the drive gear 721 counterclockwise by a predetermined angle, thereby restricting the restriction wall. The drive gear 721 is driven so that the part 724 is closed. In this state, when the motor 710 is further reversed and the drive gear 721 is rotated clockwise, the guide member 723 is also rotated clockwise by the friction between the sliding contact portion 728A and the cylindrical portion 725, and the engagement pin 735 is notched. It is locked between the restricting arc portion 727A of the portion 727 and the cylindrical portion 725 (see FIG. 17). In this state, since the engaging pin 735 is sandwiched and engaged between the restricting arc portion 727A and the cylindrical portion 725, the rotation switching plate 734 does not rotate clockwise. As a result, the third drive transmission gear 733 is brought into a contact state in which the third drive transmission gear 733 is held in mesh with the drive gear 721, and the driving force in the reverse direction of the motor 710 is transmitted to the drive gear 721, and the drive gear 721 rotates clockwise. Can be rotated.

(Operation of gear switching unit)
Next, the operation of the gear switching unit 750 in the operation of the driving unit 700 will be described based on FIG. 12 and FIGS. 18 to 22. FIG. 18 is a plan view of the drive unit 700 when the gear pedestal guide pin 751A is engaged with the first engagement portion 745A of the gear pedestal guide groove 745. FIG. FIG. 19 is a plan view of the drive unit 700 when the gear pedestal guide pin 751A is engaged with the third engagement portion 745C of the gear pedestal guide groove 745. FIG. FIG. 20 is a plan view showing a state of the gear switching unit 750 when the gear pedestal 751 is rotated counterclockwise in FIG. FIG. 21 is a plan view showing a state where the gear pedestal 751 is further rotated counterclockwise in FIG. FIG. 22 is a plan view showing the gear switching portion 750 in a state where the second engagement gear 752B and the third gear 753C are in contact with each other.

  As described above, when the third drive transmission gear 733 is engaged with the gear pedestal drive gear 741 by the reverse drive force of the motor 710 of the drive unit 700, the drive force of the motor 710 is transmitted to the gear pedestal drive unit 740. Specifically, when the third drive transmission gear 733 and the gear pedestal drive gear 741 are engaged with each other, the gear pedestal drive unit 740 transmits a drive force from the third drive transmission gear 733 to the gear pedestal drive gear 741. The With this driving force, the gear pedestal driving gear 741 rotates clockwise. Further, the rotation of the gear pedestal drive gear 741 causes the side guide pins 741A to reciprocate along the side guide grooves 743 of the gear pedestal drive plate 742. Accordingly, the gear pedestal drive plate 742 moves vertically in the longitudinal direction. It reciprocates along the direction guide groove 744. As a result, the overlapping position of the guide hole 704 of the drive pedestal 701 and the gear pedestal guide groove 745 reciprocates along the arc of the guide hole 704. Therefore, the gear pedestal guide pin 751A of the gear pedestal 751 that is engaged with the position where the guide hole 704 and the gear pedestal guide groove 745 overlap is reciprocated along the guide hole 704, and the gear pedestal 751 is moved. Rotate.

  When the gear pedestal guide pin 751A is positioned at the first engagement portion 745A of the gear pedestal guide groove 745, the second engagement gear 752B is engaged with the first gear 753A as shown in FIG. When the gear pedestal guide pin 751A is positioned at the second engagement portion 745B of the gear pedestal guide groove 745, the second engagement gear 752B is guided to the second gear 753B as shown in FIG. Further, when the gear pedestal guide pin 751A is positioned at the third engagement portion 745C of the gear pedestal guide groove 745, as shown in FIG. 19, the second engagement gear 752B is meshed with the third gear 753C.

  Here, the operation of the swing pedestal 752 when the gear pedestal 751 is rotated is shown in FIG. The state until meshing with the third gear 753C will be described as an example. FIG. 20 is a plan view showing a state of the gear switching unit 750 when the gear pedestal portion is rotated counterclockwise in FIG. FIG. 21 is a plan view showing a state of the gear switching unit 750 when the gear pedestal portion is further rotated counterclockwise in FIG. 22 is a plan view showing the gear switching portion 750 in a state where the teeth of the second engagement gear 752B and the teeth of the third gear 753C are in contact with each other when the gear base portion 751 is further rotated in FIG. It is.

  In FIG. 12, the shaft of the second engagement gear 752 </ b> B of the swing base portion 752 is engaged with the second engagement groove 754 </ b> B of the engagement plate 754. Here, when the gear pedestal 751 is rotated counterclockwise by a predetermined angle, the first engagement gear 752A also moves in the rotational direction as the gear pedestal 751 rotates. On the other hand, the shaft of the second engagement gear 752B moves in a direction away from the second gear 753B along the second engagement groove 754B of the engagement plate 754. For this reason, as shown in FIG. 20, the swing base portion 752 is in a state where the radial direction from the center of the gear base portion 751 toward the first engagement gear and the direction of the swing direction line intersect.

  Thereafter, when the gear pedestal 751 is further rotated counterclockwise, the shaft of the second engagement gear 752B is disengaged from the second engagement groove 754B. At this time, as shown in FIG. 20, the engagement plate 754 is pushed to the rear side in a state where the left push pin 752E as viewed from above is in contact with the front edge of the engagement plate 754. Then, the shaft of the second engagement gear 752B rotates around the push pin 753E as a support shaft, and comes off from the second engagement groove 754B.

  Further, one of the linear portions of the pair of torsion springs 752F extending from the spring fixing portion of the swing base portion 752 is locked to the support rod 751D of the gear base portion 751, and the other of the straight portions of the swing base portion 752 is locked. Locked to the support rod 752C. The torsion spring 752F urges the support bar 752C in the direction in which the support bar 752C is brought close to the support bar 751C. For this reason, the swing base portion 752 receives a biasing force so that the direction of the swing direction line coincides with the radial direction of the gear base portion 751. As a result, the swing base portion 752 receives a biasing force in the counterclockwise direction, and as shown in FIG. 21, pushes down the engagement plate 754 to the rear surface side by the shaft of the second engagement gear 752B.

  Thereafter, when the gear pedestal 751 is further rotated counterclockwise, the shaft of the second engagement gear is engaged with the third engagement groove 754C, and the engagement plate 754 is moved to the front side by the urging force of the torsion spring 754D. Returned to Then, the second engagement gear 752B and the third gear 753C are meshed.

  Further, the gear pedestal 751 is arranged in a state where the radial direction from the center position of the gear pedestal 751 to the first engagement gear 752A and the radial direction of the swing direction line as shown in FIG. When rotated, as shown in FIG. 22, there is a case where a so-called tooth contact occurs in which the tooth tip of the second engagement gear 752B and the tooth tip of the third gear 753C come into contact with each other (in FIG. The alternate long and short dash line on the outer periphery of the second engagement gear 752B and the third gear 753C represents the tip of the gear). In this case, by rotating the gear pedestal 751, the swinging pedestal 752 is rotated, and the second engagement gear 752B once escapes from the tooth contact state, and then meshes with the third gear 753C. . That is, the swing pedestal 752 is configured such that the swing direction line is inclined with respect to the radial direction from the center position of the gear pedestal 751 toward the first engagement gear 752A. It meshes with the three gears 753C.

  In the above, the example in which the gear pedestal 751 is rotated from the second gear 753B toward the third gear 753C has been shown, but when the gear pedestal 751 is directed from the second gear 753B to the first gear 753A, In the case of going from the third gear 753C to the second gear 753B, the same operation is performed in the case of going from the first gear 753A to the second gear 753B. Further, the operation in the state of contact between the second engagement gear 752B and the third gear 753C has been described. Even when the second engagement gear 752B contacts the first gear 753A or the second gear 753B, the same applies. Operate.

  As described above, after the gear switching unit 750 switches the gear for transmitting the driving force of the motor 710, the motor 710 is rotated forward to rotate the rotation switching plate 734 to the drive gear unit 720 side. The driving force of the motor 710 is transmitted to a predetermined gear train 753 via the drive gear 721, the first engagement gear 752A, and the second engagement gear 752B.

(Elevation control mechanism operation)
In the gear switching unit 750, when the second engagement gear 752B is engaged with the third gear 753C, the driving force of the motor 710 is transmitted through the third gear 753C, the fourth gear 753C1, and the fifth gear 753C2. Is transmitted to the movement control unit 540. Then, the movement control unit 540 drives the elevation control mechanism 500 with the transmitted driving force.

  Here, the operations of the elevation control mechanism 500 and the movement control unit 540 will be described with reference to FIGS. FIG. 23 is a plan view showing states of the elevation control mechanism 500 and the movement control unit 540 when the disk holding mechanism 320 has reached the mounting position. FIG. 24 is a plan view showing a state of the elevation control mechanism 500 and the movement control unit 540 when the disk holding mechanism 320 is moved to the insertion / ejection position. 25 to 27 are plan views showing states of the elevation control mechanism 500 and the movement control unit 540 when the pedestal unit 210 is locked. 28 and 29 are plan views showing states of the elevation control mechanism 500 and the movement control unit 540 when the disk holding mechanism 320 moves from the insertion / ejection position to the temporary fixing position.

  The disk elevating unit 300 reaches the mounting position when the elevating control mechanism 500 is in a state as shown in FIG. 23, for example. Specifically, the rotation control pin 553D of the elevation control mechanism 500 is engaged with the mounting engagement portion 564C, and the rotation control member 553C is contacted with the mounting contact portion 564D. Further, the arc portion 582B of the pedestal moving portion 580 comes into contact with the U-shaped arc portion 553C1 of the rotation control member 553C, and the protruding pin 581B is engaged with the front side locking portion 574B. Then, the holding portion 572 of the pedestal holding portion 570 moves to the rear side of the right side plate portion 124 in the longitudinal direction, so that the pedestal fixing piece 260 of the pedestal portion 210 is formed on the rising piece 575 of the holding portion 572. It moves along the taper portion 575B of the groove 575A and is locked to the base locking portion 575C. Thereby, the pedestal part 210 is lifted from the surface of the holding part 572 to the height position of the pedestal locking part 575C of the rising piece 575 and locked. Further, when the pedestal 210 is locked at a predetermined position, the entire disk processing unit 200 is also fixed at a predetermined height position, and the optical disk 1N placed on the turntable 221 is also at a predetermined height position. It will be locked.

  Further, in this state, the rotation connecting portion 562 of the rotating member 560 is closest to the rear plate portion 123, and the rotation connecting portion 563 is farthest from the rear plate portion 123. The right elevating control plate 520 is closest to the rear plate portion 123 and the left elevating control plate 530 is most separated from the rear plate portion 123. Accordingly, the right elevating control pin of the stage 310 is positioned near the lower end of the right cam groove (not shown) of the right elevating control plate 520, and the left elevating control pin is positioned near the lower end of the left cam groove 534 of the left elevating control plate 530. To do. The disk holding mechanism 320 disposed on the stage 310 has a mounting position below the lower housing 120, that is, a gap P (see FIG. 8) of the right guide 330 and a concave groove 384C of the left guide 380. It opens toward the periphery of the optical disc 1N that is pivotally supported by the turntable 221 of the rotation driving means 220, and reaches a position that can be engaged.

  In a state where the disc holding mechanism 320 is located at the mounting position, the locking claw portion of the turntable 221 is retracted from the outer peripheral surface of the shaft support portion 221A by the disc insertion / removal mechanism portion connected to the elevation control mechanism 500.

  Next, when the power transmission unit 550 is rotated counterclockwise as viewed from the upper surface side by the driving force from the driving unit 700, the rotation control pin 553D is connected to the mounting engagement unit 564C as shown in FIG. The side edge is pushed into the rear plate portion 123 side, the rotation member 560 is urged and rotated clockwise as viewed from the upper surface side, and the rotation control pin 553D is relative to the proximal end side of the mounting engagement portion 564C. Moved to. Further, the right elevating control plate 520 moves in a direction away from the rear plate portion 123, and the left elevating control plate 530 moves in a direction approaching the rear plate portion 123. Further, the right raising / lowering control pin of the stage 310 is positioned at the approximate center in the length direction of the right cam groove, and the left raising / lowering control pin is positioned at the approximately center of the left cam groove 534 in the length direction. The disc holding mechanism 320 has an insertion / ejection position that is substantially the center in the vertical direction in the lower housing 120, that is, the gap portion P of the right guide 330 and the concave groove 384C of the left guide 380 face the disc insertion opening 111A. The optical disc 1N inserted through the disc insertion opening 111A reaches a position where the periphery of the optical disc 1N can be engaged, that is, an insertion / ejection position. At this time, the opening on the tip side of the mounting engagement portion 564C and the temporary fixing engagement portion 564F is positioned on the circumference of the second virtual circle.

  Further, when the power transmission unit 550 is rotated counterclockwise as viewed from the upper surface side by the driving force from the driving unit 700, the rotation control pin 553D is moved to the pin locking groove of the base moving unit 580 as shown in FIG. It is moved to the opening position of 582A. When the power transmission portion 550 is further rotated counterclockwise, the rotation control pin 553D is engaged with the pin locking groove 582A and the pin locking portion 582 of the pedestal moving portion 580 is biased to the front side. To do. Thereby, the base movement part 580 rotates clockwise as seen from the upper surface side. Further, the protruding pin 581B of the pedestal moving part 580 that is locked to the front side locking part 574B of the V-shaped hole 574 is rotated clockwise. As a result, the protruding pin 581B biases the front side locking portion 574B in the direction toward the front side of the left side plate portion 125, and is disengaged from the front side locking portion 574B. The pedestal holding portion 570 is pushed and moved in a direction toward the front side of the left side plate portion 125 by being pushed. As the pedestal holding portion 570 moves, the holding portion 572 also moves in the direction toward the front side of the left side plate portion 125 along the longitudinal direction. Further, since the rising piece 575 also moves in the direction toward the front side of the left side plate portion 125, the pedestal fixing piece 260 locked to the pedestal locking portion 575C moves along the locking guide groove 575A, The lock of the base 210 is released. That is, the pedestal portion 210 is in a restriction release state in which the pedestal portion 210 can move in the vertical direction within a range in which it can move due to the elastic force of the soft member 210A. In the restriction release state, the disk processing unit 200 can perform the reading process and the recording process of the optical disk 1N.

  Further, when the power transmission unit 550 is rotated counterclockwise as viewed from the upper surface side by the driving force from the driving unit 700, the rotation control pin 553D is connected to the pin of the base moving unit 580 as shown in FIG. The stop groove 582A is pushed into the front side, and the pedestal moving part 580 is rotated. Then, the rotation control pin 553D is detached from the pin locking groove 582A when the opening position of the pin locking groove 582A reaches the circumference of the second virtual circle. Further, by the rotation of the pedestal moving part 580, the protruding pin 581A is rotated clockwise, and the curved part 574C of the V-shaped hole 574 is biased in the direction toward the rear surface side of the right side plate part 124, thereby the pedestal holding part 570. Move. Furthermore, the protruding pin 581A is locked to the rear surface side locking portion 574A along the curved portion 574C. Further, the rising piece 575 of the holding portion 572 moves in the direction toward the rear surface side of the right side plate portion 124, and the pedestal fixing piece 260 is locked to the pedestal locking portion 575C. Thereby, the base part 210 will be in the locked state again.

  Until the state shown in FIGS. 24 to 28, the U-shaped arc portion 553C1 of the rotation control member 553C rotates along the insertion / ejection contact portion 564B of the rotation control hole 564, and the rotation control pin 553D. Also does not contact the rotating member 560. Therefore, from the state shown in FIG. 24 to the state shown in FIG. 25, the rotation member 560 does not rotate and the disk holding mechanism 320 is maintained in the insertion / ejection position.

  Thereafter, when the power transmission unit 550 is further rotated counterclockwise as viewed from the upper surface side by the driving force of the driving unit 700, the rotation control pin 553D is placed on the circumference of the second virtual circle as shown in FIG. It moves to the opening of the temporarily fixed engagement part 564F located in the position. Here, when the power transmission portion 550 is further rotated counterclockwise, the rotation control pin 553D is engaged with the temporary fixing engagement portion 564F and the rotation control pin 553D is engaged as shown in FIG. It is relatively moved to the tip side of the temporarily fixed engaging portion 564F. Then, the rotation control pin 553D pushes the side edge of the temporary fixing engagement portion 564F to the rear surface side, and rotates the rotation member 560 clockwise. Further, when the rotation member 560 is rotated clockwise, the right elevating control plate 520 moves in a direction separating from the rear plate portion 123 and the left elevating control plate 530 is moved closer to the rear plate portion 123. Moving. Further, the right lifting control pin of the stage 310 is positioned near the upper end of the right cam groove, and the left lifting control pin is positioned near the upper end of the left cam groove 534. The disk holding mechanism 320 temporarily fixes the optical disk 1N held by the disk holding mechanism 320 detachably to the temporary fixing portion or is temporarily fixed to the temporary fixing position above the lower housing 120. The position reaches a position where 1N can be received from the temporarily fixed portion.

  In a state where the disk holding mechanism 320 is moved to the temporarily fixed position, the disk engaging / disengaging mechanism unit connected to the elevation control mechanism 500 is used to temporarily fix the optical disk 1N to the temporarily fixed unit or to release the temporarily fixed state. The optical disk 1N is transferred from the temporary fixing unit to the disk holding mechanism 320.

[Effects of disk unit]
As described above, in the above-described embodiment, when the rotation control pin 553D rotates, the pedestal moving unit 580 rotates, and the pedestal holding unit 570 moves along the longitudinal direction of the holding unit 572. Then, when the holding part 572 moves toward the rear surface side of the right side plate part 124, the base fixing piece 260 of the base part 210 is fixed to the base locking part 575C formed on the rising piece 575 of the holding part 572, The soft member 210A is in a fixed state that does not absorb vibration. On the other hand, when the holding part 572 moves toward the front side of the left side plate part 125, the base fixing piece 260 of the base part 210 is detached from the base locking part 575C, and the vibration of the disk processing part 200 can be absorbed by the soft member 210A. It becomes a non-fixed state. For this reason, when the optical disk 1N is attached to and detached from the turntable 221, the pedestal 210 is fixed, so that the optical disk 1N can be easily held only by bringing the right guide 330 and the left guide 380 close to each other at a predetermined position. Further, when the information processing unit 240 of the disk processing unit 200 performs the reading process of information on the optical disc 1N and the writing process of information to the optical disc 1N, the optical disk 1N rotates at high speed and vibrates because it is in a non-fixed state. Even if it does, since the vibration is absorbed by the soft member 210A, the processing is not affected. Therefore, the fixed state of the disk processing unit can be switched to an appropriate state with a simple configuration.

  The pedestal moving part 580 includes a pin locking part 582 on the side of the rotation control hole 564 around the rotation center position 580A, and the pedestal is located at a symmetrical position of the pin locking part 582 with respect to the rotation center position 580A. Protruding pins 581A and 581B that are engaged with the holding portion 570 are provided. For this reason, the driving force can be easily transmitted to the pedestal holding portion 570 by rotating the pedestal moving portion 580 by the driving force transmitted to the pin locking portion 582. Further, in such a configuration, since the pedestal moving unit 580 only rotates about the fulcrum, a space required for the movement of the pedestal moving unit 580 can be reduced, and the disk device 100 can be reduced in size.

  Further, the pin locking groove 582A of the pin locking portion 582 is formed to extend from the opening to the vicinity of the rotation center position 580A, and the rotation control pin 553D near the rotation center position 580A of the pin locking groove 582A. Are engaged to rotate the base moving part 580. The protruding pins 581A and 581B are provided at positions that are larger in diameter than the diameter from the rotation center position 580A to the base end portion of the pin locking groove 582A in which the rotation control pin 553D is moved. . For this reason, the movement distances of the protruding pins 581A and 581B become larger than the movement distance of the base end portion of the pin locking groove 582A with which the rotation control pin 553D is engaged. Therefore, the protruding pins 581A and 581B can push the V-shaped hole 574 with a stronger force. Therefore, the protruding pins 581A and 581B are locked by pushing the rear side locking portion 574A and the front side locking portion 574B with a stronger force. Therefore, the base holding part 570 is also moved toward the rear surface side of the right side plate part 124 with a stronger force, and the holding part 572 can fix the base part 210 more firmly.

  The projecting pins 581A and 581B of the pedestal moving part 580 are engaged with the V-shaped holes 574 of the pedestal holding part 570. For this reason, the driving force transmitted from the pin locking portion 582 can be easily transmitted from the protruding pins 581A and 581B to the V-shaped hole 574, and the pedestal portion can be easily formed by pressing the V-shaped hole 574 with the protruding pins 581A and 581B. The fixing of 210 can be switched.

  Further, the V-shaped hole 574 has hatched portions that are close to each other in the direction away from the left side plate portion 125 side, that is, the rotation center position 580A. Therefore, when the pedestal moving part 580 rotates, the projecting pin 581A or the projecting pin 581B can smoothly move along one corresponding edge of the shaded part of the V-shaped hole 574, and the edge of the shaded part can be moved. By pushing in, the pedestal holding part 570 can be moved in a direction corresponding to the rotation direction of the projecting pins 581A and 581B.

  Further, when the pedestal moving part 580 is rotated clockwise with the protruding pin 581B locked to the front side locking part 574B, the protruding pin 581B causes the front side locking part 574B to move toward the left side plate part 125. The pedestal holding portion 570 is pushed and moved toward the left side plate portion 125 along the groove of the V-shaped hole 574 by being pushed out of the locked state. When the pedestal moving part 580 rotates by a predetermined angle, the protruding pin 581A pushes in the curved part 574C of the V-shaped hole 574 and pushes the pedestal holding part 570 toward the right side plate part 124, along the curved part 574C. It is locked to the rear side locking portion 574A. For this reason, only by moving the base moving part 580 in a predetermined direction, three operations such as fixing, releasing, and fixing of the base part 210 can be performed in order. For this reason, it is not necessary to switch the rotation direction of the base moving part 580 every time the base part is fixed or not fixed. Therefore, since the fixed state and the non-fixed state can be switched only by the operation of moving the pedestal moving unit 580 in a predetermined direction, the necessary driving force for fixing and non-fixing can be suppressed, and the power consumption can be reduced. Can be reduced.

  Further, a rear side locking portion 574A and a front side locking portion 574B are formed at the rear surface side end portion and the front surface side end portion of the V-shaped hole 574, respectively. Therefore, the pedestal holding portion 570 can be positioned and fixed at a predetermined position by locking the projecting pins 581A and 581B to the rear side locking portion 574A and the front side locking portion 574B. Therefore, since the movement of the holding part 572 can be restricted, the base fixing piece 260 of the base part 210 can be maintained in a state of being locked to the base locking part 575C of the locking guide groove 575A.

  Furthermore, when the projecting pins 581A and 581B are removed from the rear side locking portion 574A and the front side locking portion 574B, the base fixing piece 260 is released from the base locking portion 575C and becomes non-fixed. Therefore, the fixed state and the non-fixed state of the pedestal part 210 can be easily switched by the movement of the holding part 572.

  The holding portion 572 has a rising piece 575 at a position corresponding to the pedestal fixing piece 260 of the pedestal portion 210, and the rising piece 575 has a taper portion 575 B along the longitudinal direction of the holding portion 572. A guide groove 575A is formed. Therefore, when the holding portion 572 is moved, the locking guide groove 575A moves, and the base fixing piece 260 moves on the taper portion 575B of the locking guide groove 575A and is locked to the base locking portion 575C. . Therefore, the pedestal part 210 can be easily fixed by moving the holding part 572.

  In addition, when the drive unit 700 rotates the second drive transmission gear 732 in a state where the restriction wall 724 is not positioned in the notch 727 of the guide member 723 and is opened, the rotation switching plate 734 is also changed. The engagement pin 735 is disengaged from the notch 727 by rotating clockwise, and the third drive transmission gear 733 is engaged with the gear base drive gear 741. Further, in a state where the restriction wall portion 724 is positioned at the notch portion 727 of the guide member 723 and is closed, when the second drive transmission gear 732 is rotated clockwise, the engagement wall 724 causes the engagement pin 735 to move. The third drive transmission gear 733 is held at a position where the third drive transmission gear 733 is engaged with the drive gear 721, and the drive gear 721 is rotated clockwise. Therefore, the driving force of one motor 710 can be transmitted to the driving gear 721 and the gear base driving gear 741 with a simple configuration, and the driving direction of the driving gear 721 can be reversed in the normal direction more easily. Therefore, the forward rotation and the reverse rotation of the rotation control pin 553D can be easily performed by the forward drive force and the reverse drive force transmitted to the drive gear 721.

  Further, when the rotation control pin 553D is detached from the pin locking portion 582, the rotation control pin 553D is engaged with the mounting engagement portion 564C and the temporary fixing engagement portion 564F of the rotation control hole 564, and the rotation control pin 553D is rotated. The stage 310 is moved up and down by rotating the member. For this reason, the rotation control pin 553D performs a fixing operation and a non-fixing switching operation of the pedestal unit 210, and also performs an ascending / descending operation of the stage 310. Therefore, the driving force transmitted from the driving unit 700 can be driven in two directions, and the driving force can be used efficiently. Therefore, a configuration such as a dedicated motor for moving the stage 310 up and down is unnecessary, the number of parts can be reduced, and the downsizing of the disk device 100 can be promoted.

[Modification of Embodiment]
Note that the present invention is not limited to the above-described embodiment, and includes the following modifications as long as the object of the present invention can be achieved.

  That is, although the example in which the V-shaped hole 574 is formed in the pedestal drive transmission portion 571 of the pedestal holding portion 570 is shown, the present invention is not limited to this. For example, it may be a hole formed in a substantially C shape whose distance is closer as it approaches the left side plate 125.

  Although the base movement part 580 is formed in a substantially fan shape, it is not limited to this. That is, the pedestal moving part 580 is provided so as to be rotatable around a rotation center position 580A, projecting pins 581A and 581B are formed on the left side plate part 125 side, and a rotation control hole 564 is provided on the right side plate part 124 side. As long as the pin engaging portion 582 is formed facing the surface, for example, it may be formed in a substantially circular shape or a substantially triangular shape.

  Further, when the left lift control plate 530 moves to the position farthest from the rear plate portion 123 and the right lift control plate 520 moves to the position closest to the rear plate portion 123, the stage 310 moves to the mounting position. However, the present invention is not limited to this. For example, when the right lifting control plate 520 moves to the position farthest from the rear plate portion 123 and the left lifting control plate 530 moves to the position closest to the rear plate portion 123, the stage 310 moves to the mounting position. It is good. In this case, the left cam groove 534 and the right cam groove (not shown) formed in the left lift control plate 530 and the right lift control plate 520 may be reversed.

  Further, although the example in which the locking guide groove 575A of the rising piece 575 is formed to open toward the rear surface side of the right side plate portion 124 is shown, it is formed to open toward the front side of the left side plate portion 125. May be. In this case, for example, the pedestal holding portion 570 is configured to be rotatably attached to the bottom plate portion 121 by the connecting portion 573 so that the rotation control pin 553D is locked to the pin locking groove 582A. When rotating in the state, the holding portion 572 rotates along the longitudinal direction to the rear surface side of the right side plate portion 124, and the base fixing piece 260 of the base portion 210 is locked to the base locking portion 575C of the rising piece 575. Can be fixed.

  Furthermore, the position where the rising piece 575 is attached is not limited to the above embodiment, and may be a position along the longitudinal direction of the holding portion 572.

  And although the example in which the rotation assistance piece 728 is formed toward the counterclockwise direction in the groove | channel formed along the circumferential direction of the guide member 723 was shown, it is not limited to this. For example, the rotation auxiliary piece 728 may be formed clockwise. Further, the rotation assisting piece 728 may not be formed, and the sliding contact portion 728A may be formed to protrude from the lower surface side of the guide member 723. However, since there is no spring force of the rotation assisting piece 728, the sliding contact portion 728A is not biased downward, and the frictional force with the cylindrical portion 725 is reduced. In this case, for example, a coil spring may be provided between the guide member 723 and a C-ring attached as a retaining member for the guide member 723 to bias the guide member toward the lower surface.

  Further, in the above embodiment, when the second drive transmission gear 732 rotates counterclockwise, the drive gear 721 also rotates counterclockwise, so that the restriction arc portion 727A is rotated clockwise from one end portion of the notch portion 727. Although it formed in the direction, it is not restricted to this. For example, when the driving force is transmitted to the driving gear 721 via a gear after the second driving transmission gear 732 and the third driving transmission gear 733, the rotational direction of the second driving transmission gear 732 and the driving gear 721 is changed. In the opposite case, the restriction arc portion 727A may be formed in the counterclockwise direction.

  And in the said embodiment, the gear switching part 750 showed the example which switches the rotation angle of the gear base part 751, and switches three gears, the 1st gearwheel 753A, the 2nd gearwheel 753B, and the 3rd gearwheel 753C. However, it is not limited to this. For example, the number of gears to which the driving force is transmitted may be two, or four or more.

  Moreover, in the said embodiment, although the base movement part 580 showed the example rotated with the rotation control pin 553D latching to the pin latching groove 582A, it is not limited to this. That is, for example, the pedestal moving unit 580 may be configured to mesh with a gear or the like and rotate. Even in such a configuration, the pedestal moving unit 580 can be rotated to move the pedestal holding unit 570, and the pedestal unit 210 can be switched between fixed and unfixed.

  In addition, the configuration in which the pedestal moving unit 580 is rotated around the rotation center position 580A is not limited to this. For example, the pedestal moving unit may reciprocate along the groove. In such a configuration, for example, by introducing a gear train that changes the driving amount between the pedestal moving unit 580 and the pedestal holding unit 570, the movement of the pedestal moving unit 580 is amplified and transmitted to the pedestal holding unit 570. It is preferable. In this configuration, even if the pedestal moving part 580 is moved slightly, a large driving force can be transmitted to the pedestal holding part 570, and the fixing force for fixing the pedestal part 210 can be strengthened.

  In addition, although the example in which the projecting pins 581A and 581B move along the V-shaped hole 574 has been shown, the projecting pins 581A and 581B may be engaged with, for example, a groove formed in an approximately C shape. Even in such a configuration, the pedestal 210 can be switched between the fixed state, the non-fixed state, and the fixed state only by rotating the pedestal moving unit 580 in a predetermined direction by a predetermined distance.

  Furthermore, although the rear side latching | locking part 574A and the front side latching | locking part 574B which were connected and formed in the V-shaped hole 574 as a latching part were illustrated, it does not restrict to this. For example, as a locking part, it is good also as a structure which attaches a hook-shaped member to the front side and rear surface side edge part of the V-shaped hole 574, and locks it by hooking the protruding pins 581A and 581B with a hook member. Moreover, it is good also as a structure provided with the movement control pin which controls the movement of protrusion pin 581A, 581B. In this configuration, for example, when the projecting pin 581A or the projecting pin 581B reaches the front surface side or the rear surface side of the V-shaped hole 574, and the rotation control pin 553D is removed from the pin locking groove 582A, the movement restricting pin is the projecting pin 581A or projecting. The pin 581B is locked.

  In the above embodiment, when the protruding pin 581A or the protruding pin 581B is locked to the locking portion, the pedestal holding portion moves to the right side plate portion 124 side to fix the pedestal portion 210, and the protruding pin 581A or the protruding pin Although the example in which the pedestal holding part 570 moves to the left side plate part 125 side and the fixing of the pedestal part 210 is released when the pin 581B is removed from the locking part is shown, the present invention is not limited to this. For example, in a state where the protruding pin is locked to the locking portion, the fixing of the pedestal portion 210 is released, that is, in a non-fixed state, and the pedestal portion 210 is fixed when the protruding pin is separated from the locking portion. Good.

  Further, the rising piece 575 is formed in the holding portion 572, and the rising piece 575 is provided with the locking guide groove 575A for fixing the pedestal fixing piece 260 of the pedestal portion 210. An upright piece having a guide groove may be formed, and a fixed piece protruding from the holding portion 572 may be engaged with the locking guide groove. Even in such a configuration, only by moving the pedestal holding portion 570, the locking guide groove of the pedestal portion 210 can move along the fixed piece and can be fixed by the locking portion.

In addition, the specific structure and procedure for carrying out the present invention can be appropriately changed to other structures and the like within a range in which the object of the present invention can be achieved.
[Effect of the embodiment]
As described above, in the above-described embodiment, when the rotation control pin 553D rotates, the pedestal moving unit 580 rotates, and the pedestal holding unit 570 moves along the longitudinal direction of the holding unit 572. When the holding portion 572 moves toward the rear surface side of the right side plate portion 124, the pedestal portion 210 is fixed and locked in a fixed state where the soft member 210A does not absorb vibration, and the holding portion 572 is on the front side of the left side plate portion 125. When moving toward, the pedestal 210 is unlocked, and the soft member 210A enters a non-fixed state in which the vibration of the disk processing unit 200 can be absorbed. For this reason, when the optical disk 1N is attached to and detached from the turntable 221, the pedestal 210 is fixed, so that the optical disk 1N can be easily held only by bringing the right guide 330 and the left guide 380 close to each other at a predetermined position. Further, when the information processing unit 240 of the disk processing unit 200 performs the reading process of information on the optical disc 1N and the writing process of information to the optical disc 1N, the optical disk 1N rotates at high speed and vibrates because it is in a non-fixed state. Even if it does, since the vibration is absorbed by the soft member 210A, the processing is not affected. Therefore, the fixed state of the disk processing unit can be switched to an appropriate state with a simple configuration.
