The disc guide portion 532 is formed in a semi-cylindrical shape with the vertical direction from the bottom surface to the top surface as an axis, and the inner side is formed in an arc shape. The disk guide unit 532 is in contact with the peripheral edge of the conveyed optical disk 1 and holds the optical disk 1 together with the roller 513 of the loading arm 51 when the optical disk 1 is conveyed. Further, when the maximum diameter portion of the large-diameter disc 1A passes, the disc guide arm 53 is rotated to the position closest to the left wall 10B side. The disc guide portion 532 is formed in a semi-cylindrical shape as described above. Therefore, disc guide 532 and left wall 10B do not interfere. Accordingly, it is possible to guide the conveyance of the optical disc 1 without increasing the lateral width of the disk device 100, and it is possible to cope with the downsizing. Furthermore, a disk guide pin 533 protruding toward the bottom surface is formed on the left wall lOB side of the base end portion of the disk guide arm 53. The disk guide pin 533 moves to the front 10A side when the disk guide arm 53 rotates to the left wall 10B side, and moves to the back surface 10D side when the disk guide arm 53 rotates to the right wall 10C side.

[0048] Similar to the loading arm 51, such a disc guide arm 53 is rotated to the left wall 1OB side to a position where the optical disc 1 can be guided according to the diameter of the optical disc 1 being conveyed. For example, when transporting the large-diameter disc 1A, the disc guide arm 53 is rotated to the vicinity of the left wall 1OB. On the other hand, when transporting a small-diameter disc 1B, the disc guide arm 53 has a distance of about 4 cm between the center line (center line L), in which the rotational center force of the turntable 23 extends back and forth, and the disc guide portion 532. It is rotated to the left wall 10B side to the position. In the playable state, the disc guide arm 53 is rotated to the vicinity of the left wall 10B side, and the disc guide portion 532 is separated from the periphery of the optical disc 1.

The disc guide link mechanism 54 includes a disc guide slide plate 541 and a disc guide link 542.

[0050] The disc guide slide plate 541 is formed longitudinally in the front-rear direction so as to face the left wall 10B. Further, on the front surface 10A side of the disc guide slide plate 541, a first disc guide link engaging portion 541A is formed in which the edge force on the bottom surface side extends toward the rotating shaft of the disc guide arm 53. The first disc guide link engaging portion 541A is formed with a first disc guide link groove 541B that is elongated in the left-right direction, and a disc guide pin 533 is engaged therewith. The disc guide slide plate 541 slides in the front-rear direction when the disc guide pin 533 moves in the front-rear direction by the rotation of the disc guide arm 53.

In addition, a second disk guide link engaging portion 541C that protrudes inward of the housing 10 is formed on the back surface 10D side of the disk guide slide plate 541. The second disc guide engaging portion 541C is formed with a second disc guide engaging groove 541D in which the left wall 10B side force is also inclined toward the front surface 10A side of the right wall 10C.

[0052] Further, a loading guide groove 541E extending in the front-rear direction is formed at a substantially central position in the front-rear direction of the disc guide slide plate 541, so that the disc guide slide play Guides the slide movement direction of G541.

The disc guide link lever 542 is provided so as to be rotatable about a rotation shaft 542A provided on the bottom surface of the top plate 17. Further, the disc guide link lever 542 includes a first guide lever 542B and a second guide lever 542C that extend at a predetermined angle with respect to the rotation shaft 542A. The first guide lever 542B is formed with a first guide lever pin 542D protruding so that the tip side force is also directed toward the top surface. The first guide lever pin 542D is engaged with the second disk guide engagement groove 541D of the second disk guide link engagement portion 541C. Thus, when the disc guide slide plate 541 slides to the front 10A side, the first guide lever pin 542D also moves to the front 10A side, and the disc guide link lever 542 rotates counterclockwise. On the other hand, when the disk guide slide plate 541 slides and moves to the back surface 10D side, the first guide lever pin 542D also moves to the back surface 10D side, and the disk guide link lever 542 rotates in the clockwise direction.

[0054] Further, the second guide lever 542C has a second guide lever pin 542E formed so as to project the tip side force toward the bottom side. The second guide lever pin 542E is engaged with a link plate 55 described later. Further, a spring mounting portion 542F is provided at the tip of the second guide lever 542C, and a spring (not shown) is attached between the link plate 55 and the second guide lever 542C. As a result, the disc guide link lever 542 is always applied with an urging force in the counterclockwise direction. Accordingly, the disc guide slide plate 541 is always urged toward the back surface 10D side, and the disc guide arm 53 is urged so that the tip portion moves toward the center side of the housing 10.

The link plate 55 is a plate-like member that is provided on the back surface 10D side of the housing 10 and is formed in a longitudinal shape in the left-right direction.

These lever pin engaging portions 552A are grooves extending in the front-rear direction, and the second lever pin 523E and the second guide lever pin 542E are engaged with the groove. When the second lever pin 523E and the second guide lever pin 542E are moved and the left and right walls of the lever pin engaging portion 552A are pushed, the link plate 55 is slid in the left and right direction.

[0058] Further, the lever pin engaging portion 552A is formed such that the distance in the left-right direction of the groove is slightly larger than the diameters of the second lever pin 523E and the second guide lever pin 542E. Thus, a gap 552B is formed in the left-right direction between the second lever pin 523E, the second guide lever pin 542E, and the lever pin engaging portion 552A.

The gap 552B is a rotational play in which the loading link lever 523 and the disc guide link lever 542 escape when an impact is applied to the disc device 100 during the conveyance of the optical disc 1, for example. That is, when there is no gap 552B, when an impact is applied, for example, when the loading arm 51 moves to the right wall 10C side due to the impact, the disk guide arm 53 also moves to the left wall 10B side in conjunction with it. End up. For this reason, the loading arm 51 and the disc guide arm 53 cannot hold the periphery of the optical disc 1, and the optical disc 1 may drop and cause a malfunction. On the other hand, in the configuration in which the gap 552B is provided, even if the impact is applied and, for example, the loading arm 51 moves slightly to the right wall 10C side, the disc guide arm 53 does not move, and the optical disc 1 is prevented from falling. It is possible to do this.

[0059] Further, on the right wall 10C side of the lever engagement window 552, a spring engagement portion 552C is formed. This spring engagement part 552C is not shown between the spring attachment parts 523F and 542F. There are no springs to urge the loading link lever 523 and disc guy drink lever 542 clockwise as described above.

[0060] Eject regulating window 553 is a window formed substantially at the center of link plate 55.

When the clamper raising / lowering pin 21C is engaged with the performance state portion 715D, the information processing portion 24 enters a performance ready state in which information on the optical disc 1 is processed.

Further, in the vicinity of the back surface 10D side of the first shift cam 71, for example, a fourth switch SW4 mounted on the control circuit unit 80 disposed on the bottom surface is disposed. The fourth switch SW4 detects the swinging state of the disk processing unit 20. Specifically, the fourth switch SW4 detects the swinging state of the disk processing unit 20 by detecting the moving state of the first shift cam 71 that swings the disk processing unit 20.

[0093] The fourth switch SW4 is connected to the control circuit unit 80 and is configured to include a switch body and a movable piece, as in the case of the switches SW1, SW2, and SW3. In the initial state, the fourth switch SW4 is movable piece. Is pushed by the end face of the left wall 10B of the first shift cam 71. Then, when the first shift cam 71 moves to the front 10A side, the movable switch protrudes and the fourth switch SW4 is turned off (H level). In this way, the control circuit unit 80 recognizes the switching of the 0? ^ 0 state (11 level) of the fourth switch SW4 and recognizes the detection state of the fourth switch SW4.

[0094] The second shift cam slides in the left-right direction in conjunction with the operation of the first shift cam 71. That is, when the first shift cam 71 moves to the front 10A side, the second shift cam moves to the left wall 10B side, and when the first shift cam 71 moves to the back surface 10D side, the second shift cam moves to the right wall 10C side. . Further, a clamper lift groove (not shown) having the same shape as the clamper lift groove 715 of the first shift cam 71 is formed on the end face on the front face 10A side of the second shift cam. A clamper raising / lowering pin 21C (not shown) that protrudes from the pedestal portion 21 to the rear surface 10D side is engaged with the clamper raising / lowering groove. The second shift cam moves in the left-right direction to swing the disk processing unit 20 in the same manner as the first shift cam 71.

[0096] (Large-diameter disk loading operation)

First, the carrying-in operation when the large-diameter disk 1A is inserted into the disk device 100 will be described.

As shown in FIG. 5, when a large-diameter disk 1A is inserted from the loading / unloading rod 14 of the disk device 100 in the initial state, the peripheral edge of the large-diameter disk 1A becomes the roller 513 and the disk of the loading arm 51. It contacts the disc guide 532 of the guide arm 53. In this state, when the large-diameter disc 1A is inserted into the back surface 10D side, the loading arm 51 rotates to the right wall 10C side, and the disc guide arm 53 rotates to the left wall 10B side. As a result, in conjunction with the rotation of the loading arm 51 and the disc guide arm 53, the link plate 55 also slides to the left wall 10B side.

Then, when the switch piece 556 of the link plate 55 comes into contact with the movable piece of the second switch SW2 and the second switch SW2 is turned on (L level) (T1 in FIG. 14), the disk device 1 00 The control circuit unit 80 controls to drive the drive motor 41 of the drive unit 40. As a result, the driving force of the drive motor 41 is transmitted to the roller 513 of the loading arm 51, and the roller 513 is driven to rotate in the direction in which the large-diameter disk 1A is pulled into the housing 10 (T2 in FIG. 14). .

[0099] Further, the loading arm 51 and the disc guide arm 53 are composed of the roller 513 and the In the state where the center of the center hole of the large-diameter disk 1A is slightly shifted to the left side of the center line L by the disk guide portion 532, the conveyance of the large-diameter disk 1A is guided. When the roller 513 and the disc guide portion 532 hold the maximum diameter portion of the large-diameter disc 1A, the loading arm 51 and the disc guide arm 53 rotate to the positions closest to the right wall 10C and the left wall 10B, respectively. To do. At this time, the right wall 10C side of the roller 513 is inserted into a relief hole formed in the right wall 10C, and the interference between the roller 513 and the right wall 10C is prevented.

[0100] After that, when the large-diameter disk 1A is further carried into the housing 10 manually and by the driving force of the roller 513, the insertion tip of the large-diameter disk 1A is the first disk of the first eject arm 61. Contact the contact portion 612. When the large-diameter disc 1A is further carried into the back surface 10D side by the roller 513, the first eject arm 61 is rotated. At this time, the large-diameter disk 1A is carried so as to be sandwiched between the first disk contact portion 612 of the first eject arm 61 and the second disk contact portion 622 of the second ejector arm 62, The center of the center hole of the large-diameter disk 1A is moved on the center line L of the disk device 100.

[0101] Further, when the large-diameter disc 1A is moved to the back surface 10D side, the link plate 55 is further moved to the left wall 10B side. Accordingly, as shown in FIG. 6, the switch piece 550 comes into contact with the movable piece of the first switch SW1, and the first switch SW1 is turned on (L level) (T3 in FIG. 14).

Thereafter, when a large-diameter disc 1 is further inserted, the eject pin 611 is engaged with the large-diameter restricting / engaging portion 553B, and the movement of the first eject arm 61 is restricted. When the large-diameter disc 1A is inserted, the loading arm 51 and the disc guide arm 53 rotate to the vicinity of the right wall 10C and the left wall 10B, respectively, so that the link plate 55 also moves greatly to the left wall 10B side. To do. For this reason, the select pin 554 of the link plate 55 also releases the force of the pin engaging portion 733A of the select arm 73, and the select arm 73 rotates in the clockwise direction. Accordingly, the cam push pin 613 of the first eject arm 61 does not come into contact with the second push wall portion 735 of the select arm 73, but rotates and comes into contact with the first push wall portion 713. Further, the cam control pin 555 moves to the connecting portion of the standby groove 712A of the cam groove 712 and the cam groove 712C for 12 cm disk by the movement of the link plate 55. [0103] Then, as shown in Fig. 7, when the large-diameter disc 1A is completely loaded and moved above the turntable 23 (T4 in Fig. 14), the cam push pin 613 is moved to the first push-out. Push the wall 713 to the 10A side. As a result, the first shift cam 71 is moved to the front 10A side, and the rack 711 and the pinion gear 425B of the cam shift gear 425 are engaged. Then, the first shift cam 71 is moved to the front 10A side by the driving force transmitted from the driving unit 40, and the clamping operation is started.

The clamping operation is performed by moving the clamper lifting pins 21 C of the pedestal portion 21 in the clamper lifting grooves 715 of the first shift cam 71 by the movement of the first shift cam 71. Specifically, when the first shift cam 71 starts to move, the clamper elevating pin 21C is disposed in the retracting portion 715A, and the pedestal portion 21 corresponds to the height position of the retracting portion 715A. Located on the bottom side.

[0105] In this state force as well, when the first shift cam 71 moves to the front surface 10A side, the clamper elevating pin 21C moves to the standby portion 715B. As a result, the pedestal 21 is raised and lowered at a height position corresponding to the standby unit 715B, and the position correction between the center hole of the optical disc 1 and the disk engaging portion 23A of the turntable 23 is performed.

[0106] Further, when the first shift cam 71 moves to the front face 10A side, the clamper elevating pin 21C moves to the clamp portion 715C. As a result, the pedestal 21 moves to the top surface side, the large-diameter disk 1A is sandwiched between the turntable 23 and the clamp member provided on the top surface, and the center of the large-diameter disk 1A is inserted into the disk engaging portion 23A. The hole is engaged and the clamping operation is completed. Thereafter, when the clamper elevating pin 21C moves to the performance state portion 715D, the pedestal portion 21 moves to a height position where the information processing unit 24 can process the information on the large-diameter disc 1A, as shown in FIG.

[0107] During this clamping operation, the cam control pin 555 moves to the clamp groove 712D through the 12cm disc cam groove 712C. As a result, the link plate 55 is further moved to the left wall 10B, and the eject pin 611 is also moved to the large-diameter restriction engagement portion 553D. That is, the first and second eject arms 61 and 62 are rotated to the back surface 10D side so that the first and second disc contact portions 612 and 622 are separated from the peripheral force of the large-diameter disc 1A. At this time, the eject pin 611 is moved to the eject arm restricting groove 171. Set the third switch SW3 on the bottom side of the switch to the ON state (L level) (T5 in Fig. 14).

) o

[0108] Furthermore, as the link plate 55 moves, the loading arm 51 and the disc guide arm 53 also rotate to the vicinity of the right wall 10C and the left wall 10B, respectively, and the roller 513 and the disc guide portion 532 have a large diameter. Separate from the periphery of disc 1A.

[0109] After that, when the first shift cam 71 further moves to the front 10A side, the movable piece of the fourth switch SW4 and the end surface of the first shift cam 71 are separated from each other and become the OFF state (H level) (in FIG. 14). T6). As a result, the control circuit 80 recognizes that the clamping of the large-diameter disk 1A has been completed, and stops the drive motor 41 (中 7 in FIG. 14). Here, the control circuit unit 80 determines the diameter of the optical disc 1 inserted according to the state of the third switch SW3 and the fourth switch SW4. That is, when the fourth switch SW4 is in the OFF state (low level) and the third switch SW3 is in the ON state (L level), the control circuit unit 80 determines that the inserted optical disk 1 is the large diameter disk. Judge as 1A. On the other hand, as will be described later, if the third switch SW3 is in the OFF state (H level) when the fourth switch SW4 is in the OFF state (H level), the inserted optical disc 1 is the small-diameter disc 1B. to decide.

[0110] Then, the control circuit unit 80 controls the drive of the information processing unit 24 of the disk processing unit 20 to process the information on the large-diameter disk 1A, that is, to write information to the large-diameter disk 1A. If it is a loading process, a reading process is performed to read the information recorded on the large-diameter disc 1A.

[0111] (Large-diameter disk unloading operation)

Next, the carry-out operation of the large-diameter disk 1A will be described.

When the control circuit unit 80 of the disk device 100 recognizes an input signal indicating that the large-diameter disk 1A is to be unloaded, for example, when an unillustrated eject button is pressed, the large-diameter disk 1A is unloaded to the outside of the housing 10. The operation to be performed is performed. That is, the control circuit unit 80 first controls to drive the drive motor 41.

[0112] As an operation to carry out, the control circuit unit 80 first drives the drive motor 41 of the drive unit 40 (T8 in Fig. 14) to move the first shift cam 71 to the back surface 10D side. As the first shift cam 71 moves toward the rear surface 10D, the fourth switch SW4 is turned on (L level) (T9 in FIG. 14). Further, as the first shift cam 71 moves toward the back surface 10D, the cam control pin 555 moves in the cam groove 712, and the link plate 55 moves toward the right wall 10C. Accordingly, the loading arm 51, the disc guide arm 53, the first and second eject arms 61 and 62 are rotated in conjunction with the link plate 55, the optical disc 1 is the roller 513, the disc guide portion 532, the first and the second It is held by the second disk contact portions 612 and 622. In this state, the third switch SW3 is turned off (H level) (T10 in Fig. 14).

In this state, when the first shift cam 71 further moves to the back surface 10D side, the pedestal portion 21 moves to the bottom surface side, so that the large-diameter disc 1 is detached from the turntable 23.

[0113] After that, the large-diameter disc 1A is conveyed to the front 10A side by driving the roller 513 of the loading arm 51 and the urging force of the first and second eject arms 61, 62, and the rod discharge force 1 4 Are discharged. Further, as shown in FIG. 9, the control circuit unit 80 drives when the link plate 55 moves to the right wall 10C side and the first switch SW1 is turned off (H level) (T11 in FIG. 14). The motor 41 is stopped (T12 in Fig. 14), and the driving of the roller 513 is stopped.

[0114] (Importing small-diameter discs)

Next, the carrying-in operation when the small-diameter disk 1B is inserted into the disk device 100 will be described. As shown in FIG. 10, when the small-diameter disk 1B is inserted from the loading / unloading rod 14 of the disk apparatus 100 in the initial state, the peripheral edge of the small-diameter disk 1B is the disk 513 of the loading arm 51 and the disk of the disk guide arm 53. Abuts against guide part 532. In this state, when the small-diameter disc 1 is further inserted into the rear surface 10D side, the loading arm 51 rotates to the right wall 10C side, and the disc guide arm 53 rotates to the left wall 10B side. As a result, in conjunction with the rotation of the loading arm 51 and the disc guide arm 53, the link plate 55 also slides to the left wall 10B side.

[0115] When the switch piece 556 of the link plate 55 comes into contact with the movable piece of the second switch SW2 and the second switch SW2 is turned on (L level) (T13 in FIG. 15), the disk device 100 The control circuit unit 80 controls the drive motor 41 of the drive unit 40 to be driven. As a result, the driving force of the drive motor 41 is transmitted to the roller 513 of the loading arm 51, and the roller 513 is rotationally driven in the direction of pulling the small-diameter disk 1B into the housing 10 (Τ14 in FIG. 15). . [0116] After that, when the small-diameter disc IB is further carried into the housing 10 manually and by the driving force of the roller 513, the insertion tip of the small-diameter disc 1B comes into contact with the first disc of the first eject arm 61. It contacts the part 612. When the small-diameter disc 1B is further carried into the back surface 10D side by the roller 513, the first eject arm 61 is rotated. At this time, the small-diameter disk 1B is carried so as to be sandwiched between the first disk abutting part 612 of the first eject arm 61 and the second disk abutting part 622 of the second ejector arm 62, and the small-diameter disk 1B The center of 1B is moved on the center line L of the disk unit 100.

[0117] Further, when the small-diameter disc 1B is moved to the back surface 10D side, the link plate 55 is further moved to the left wall 10B side. Accordingly, as shown in FIG. 11, the switch piece 550 comes into contact with the movable piece of the first switch SW1, and the first switch SW1 is turned on (L level) (T15 in FIG. 15).

Thereafter, when the small-diameter disc 1B is further inserted, the eject pin 611 is engaged with the small-diameter restricting / engaging portion 553, and the movement of the first eject arm 61 is restricted. Further, the cam push pin 613 of the first ejector arm 61 comes into contact with the second push wall portion 735 of the select arm 73. Further, at this time, the cam control pin 555 moves to the connecting portion of the standby groove 712A of the cam groove 712 and the cam groove 712B for 8 cm disc by the movement of the link plate 55.

Then, as shown in FIG. 12, when the small-diameter disk 1B is completely loaded and the small-diameter disk 1B is moved above the turntable 23 (T16 in FIG. 15), the cam push pin 613 is moved to the first position. 2 Extrude the extruded wall 735 to the front 10A side. As a result, the first shift cam 71 is moved to the front surface 10A side, and the rack 711 and the pion gear 425B of the cam shift gear 425 are engaged. Then, the first shift cam 71 is moved to the front 10A side by the driving force transmitted from the driving unit 40, and the clamping operation is started. The clamping operation is the same as the operation of the large-diameter disk 1A described above, and a description thereof is omitted here.

[0120] During the clamping operation, the cam control pin 555 moves to the clamp groove 712D through the 8 cm disc cam groove 712B. As a result, the link plate 55 is further moved to the left wall 10B, and the eject pin 611 is moved from the small diameter restricting / engaging portion 553A to the small diameter separating / engaging portion 553C. That is, the first and second eject arms 61, 62 are arranged on the rear surface 10D side so that the first and second disc contact portions 612, 622 are separated from the peripheral edge force of the small-diameter disc 1B. To turn.

[0121] Further, by the movement of the link plate 55, the loading arm 51 and the disk guide arm 53 rotate to the vicinity of the right wall 10C and the vicinity of the left wall 10B, respectively, and the roller 513 and the disk guide portion 532 become the small diameter disk. Separated from the periphery of 1B.

[0122] Thereafter, when the first shift cam 71 further moves to the front 10A side, the movable piece of the fourth switch SW4 and the end face of the first shift cam 71 are separated from each other as shown in FIG. (T17 in Fig. 15). As a result, the control circuit unit 80 recognizes that the clamping operation is completed, and stops the drive motor 41 (18 in FIG. 15). Here, as described above, the control circuit unit 80 determines the diameter of the optical disc 1 inserted according to the state of the third switch SW3 and the fourth switch SW4. That is, if the third switch SW3 is in the OFF state (H level) when the fourth switch SW4 is in the OFF state (high level), the control circuit unit 80 determines that the inserted optical disc 1 is the small-diameter disc 1B. Judge that there is.

Then, the control circuit unit 80 controls the driving of the information processing unit 24 of the disk processing unit 20 to process information on the small-diameter disk 1B, that is, a writing process for writing information to the small-diameter disk 1B or a small-diameter disk. 1 Read the information recorded in B.

[0123] (Small-diameter disk unloading operation)

Next, the carry-out operation of the small-diameter disk 1B will be described.

When the control circuit unit 80 of the disk device 100 recognizes an input signal indicating that the small-diameter disk 1B is to be unloaded, for example, when an unillustrated eject button is pressed, the operation of unloading the small-diameter disk 1B to the outside of the housing 10 is performed. To implement. That is, the control circuit unit 80 first controls to drive the drive motor 41.

[0124] In this carry-out operation, the control circuit unit 80 first drives the drive motor 41 of the drive unit 40 (T19 in FIG. 15) in the same manner as the carry-out operation of the large-diameter disc 1A. Move the back to the 10D side. As the first shift cam 71 moves toward the rear surface 10D, the fourth switch SW4 is turned on (L level) (T20 in FIG. 15).

Further, as the first shift cam 71 moves toward the back surface 10D, the cam control pin 555 moves in the cam groove 712, and the link plate 55 moves toward the right wall 10C. Therefore, the loading arm 51, the disk guide arm 53, the first and the second are interlocked with the link plate 55. The eject arms 61 and 62 rotate, and the small-diameter disk 1B is held by the roller 513, the disk guide part 532, and the first and second disk contact parts 612 and 622. In this state, when the first shift cam 71 further moves to the rear surface 10D side, the pedestal portion 21 moves to the bottom surface side, so that the small-diameter disk 1B is detached from the turntable 23.

Thereafter, the small-diameter disc 1B is transported to the front surface 10A side by the driving of the roller 513 of the loading arm 51 and the urging force of the first and second eject arms 61, 62. During the transfer of the small-diameter disk 1B to the front surface 10A, the first switch SW1 is in the OFF state (H level) (T21 in FIG. 15), but the control circuit unit 80 performs the above loading operation. In this case, since it is determined that the optical disk 1 carried in is the small-diameter disk 1B, the drive of the drive motor 41 should not be stopped here! /.

After that, when the small-diameter disc 1B is carried out to the front 10A side, the small-diameter disc 1B is ejected from the scissor exhaust 14. When the second switch SW2 is turned off (H level) (T22 in FIG. 15), the control circuit unit 80 stops the drive motor 41 (Τ23 in FIG. 15) and stops the driving of the roller 513. Let

[Operational effects of the disk device]

As described above, in the disk device 100 of the above-described embodiment, the disk processing unit 20, the drive motor 41, the drive transmission gear group 42, and the loading arm 51 are provided in the vicinity of the soot and drain 14. For this reason, it is possible to effectively use the space that does not interfere with the swinging of the disk processing unit 20 of the waste gas exhaust 14, and the drive motor 41, the drive transmission gear group 42, and the loading as described above are used in this space. An arm 51 can be arranged. Therefore, the disk device 100 that does not require the drive motor 41, the drive transmission gear group 42, and the loading arm 51 to be disposed at various locations of the disk device 100 as in the prior art can be reduced in size. Therefore, the present invention can be applied to, for example, a thin disk device 100 mounted on a notebook personal computer.

[0127] Also, the disk processing unit 20 is arranged on the left wall 10B side of the casing main body 11, and the loading arm 51 is arranged on the wing 12 having a thickness smaller than that of the casing main body 11. . For this reason, the space on the right wall 10C side of the disk processing unit 20 becomes larger. Therefore, the drive motor 41, the drive transmission gear group 42, and the first shift cam 71 are arranged in this space without difficulty. And miniaturization can be achieved.

Furthermore, the loading arm 51 includes a roller 513 that is driven to rotate. Then, by guiding the transport direction of the optical disc 1 by the disc guide portion 532 of the disc guide arm 53 and rotating the roller 513, the optical disc 1 is rotated by the roller 513 and rolled along the transport path. For this reason, since the conveyance path is surely set in the disk guide portion 532, the optical disk 1 can be reliably conveyed to the inside without the conveyance path of the optical disk 1 being shifted by the driving force of the roller 513.

Further, the disc guide arm 53 rotates so as to be able to hold the outer peripheral edge of the optical disc 1 according to the diameter size of the optical disc 1, so that even the optical disc 1 having a different diameter size is surely transported along the transport path. be able to.

Here, the roller 513 is provided at a position where it can come into contact with the outer peripheral edge of the optical disc 1, that is, at a position intersecting the transport surface of the optical disc 1, and the roller drive unit 512 is the main body of the loading arm. It is provided between 511 and the wing part 12. For this reason, the roller driving unit 512 does not interfere with the optical disk 1 being conveyed, and the roller 513 can be rotated and driven in a limited space.

[0130] A disc guide arm 53 is provided on the left wall 10B side of the disc device 100 on the opposite side of the loading arm 51 with respect to the transport path. With the guide portion 532 in contact with the outer peripheral edge of the optical disc 1, the guide portion 532 rotates according to the diameter of the optical disk 1. For this reason, the conveyance path can be guided corresponding to each of the large-diameter disk 1A and the small-diameter disk 1B. Therefore, even in the thin slot-in type disk device 100, the optical disks 1 having different diameters can be transported into the housing 10 in accordance with the respective diameters.

[0131] Further, the disc guide portion 532 of the disc guide arm 53 is formed in a semi-cylindrical shape, and does not interfere with the left wall 10B side at a position where the disc guide arm 53 is closest to the left wall 10B side. For this reason, the lateral width of the disk device 100 can be further reduced, and the miniaturization can be promoted.

Furthermore, at the position where the loading arm 51 is closest to the right wall 10C side, the roller 513 is passed through the escape hole 10C1 provided in the right wall 10C. For this, Laura 513 and right Wall IOC interference can be prevented. Therefore, the left and right width of the disk device 100 can be further reduced, and downsizing can be promoted.

Then, the loading arm 51 and the disk guide arm 53 are connected to each other by the loading link mechanism 52, the disk guide link mechanism 54, and the link plate 55 on the back surface 10D side of the disk device 100. For this reason, the loading arm 51 and the disk guide arm 53 can be interlocked. Therefore, the optical disc 1 can be reliably transported along the transport path according to the diameter. In addition, a link plate 55 that slides to the left and right is disposed on the rear surface 10D of the housing 10. For this reason, since the disk processing unit 20 and the link plate 55 do not overlap in the vertical direction, these interferences can be prevented and the thickness can be reduced.

[0134] In the link guide groove 551 of the link plate 55, a gap 552B is formed in the left-right direction between the first and second lever pins 523E, 542E and the lever pin engaging portion 552A. For this reason, even when an impact is applied to the disc device 100, the impact can be absorbed by the gap 552B, and the optical disc 1 can be prevented from being detached during the transport.

[0135] Then, when inserting the optical disc 1, the loading arm 51 and the disc guide arm 53 allow the center line L force of the center hole of the optical disc 1 to pass through the line slightly shifted to the left wall 10B side. .

[Modification of Embodiment]

The present invention is not limited to the above-described embodiment, but includes the following modifications as long as the object of the present invention can be achieved.

That is, in the above embodiment, the disk device 100 is an example of a thin disk device that can be mounted on a notebook personal computer or the like, but is not limited thereto, and is mounted on, for example, a desktop personal computer. It can also be applied to relatively large disk devices.

[0138] In addition, the disk device 100 includes a large-diameter disk 1A and a small-diameter disk 1B inside the casing 10. However, the present invention is not limited to this. For example, it is possible to deal with more disk diameters. In this case, the movement of the link plate 55 is controlled in accordance with the respective disk diameters, and the rotation angles of the loading arm 51, the disk guide arm 53, and the first and second eject arms 61, 62 are appropriately set. Good

[0139] The loading arm 51 and the disc guide arm 53 may not be interlocked. In this case, it is possible to transport the large-diameter disk 1A and the small-diameter disk 1B by providing another drive unit that rotates the disk guide arm 53 according to the diameter of the optical disk 1.

[0140] Further, a force that forms a gap 552B between the second lever pin 523E and the second guide lever pin 542E and the lever pin engaging portion 552A, whichever of the second lever pin 523E and the second guide lever pin 542E Alternatively, a gap 552B may be provided between one of them and the lever pin engaging portion 552A. Even in such a configuration, it is possible to prevent the optical disk 1 from being detached due to the interlocking of the loading arm 51 and the disk guide arm 53 when an impact is applied to the disk device 100.

[0141] Furthermore, in the above-described embodiment, the force for conveying the optical disc 1 along the line in which the center line L force is also slightly shifted toward the left wall 10B is not limited to this. For example, it may be conveyed along the center line L which may be conveyed along the line shifted to the right wall 1 OC side.

[0142] Further, although the example in which the disc guide portion 532 is formed in a semi-cylindrical shape is shown, it may be formed in a cylindrical shape. In this case, interference between the left wall 10B and the disc guide portion 532 can be prevented by forming a relief hole portion on the left wall 10B side to avoid interference with the disc guide portion 532. Further, the disc guide portion 532 is not limited to a cylindrical shape and a semi-cylindrical shape, and may be formed in a wrinkled shape capable of holding the optical disc 1 in contact with a point or a line, such as a square pole.

In addition, the specific structure and procedure for carrying out the present invention can be changed as appropriate to other structures and the like within a range in which the object of the present invention can be achieved.

[Effect of the embodiment] In the disk device 100 of the above-described embodiment, the disk processing unit 20, the drive motor 41, the drive transmission gear group 42, and the loading arm 51 are provided in the vicinity of the rod exhaust 14. For this reason, a space that does not interfere with the swing of the disk processing unit 20 of the slag 14 can be effectively utilized. As described above, the drive motor 41, the drive transmission gear group 42, and the loading arm 51 can be used in this space. Can be arranged. Therefore, the disk device 100 that does not require the drive motor 41, the drive transmission gear group 42, and the loading gear 51 to be arranged at various locations of the disk device 100 as in the conventional art can be reduced in size.
