Description

 Specification

 Disk drive

Technical field

 The present invention relates to a disc drive device for setting a disc such as a CD (Compact Disc) or an MD (Mini Disc) on a tray, and pulling out the tray to take out the disc.

Background art

 Conventional changer mechanism disc storage and transport mechanisms include a carousel method in which a plurality of discs are placed on a disk and rotated and switched, and a type in which a plurality of trays are stacked up and down and moved horizontally. . The latter type includes a magazine type, a bank type, an independent tray type, and the like.However, in terms of operation, the trays rotate and move horizontally, or a combination of them to store and transport disks. I'm wearing

 In addition, a conventional disk drive, particularly a changer mechanism having a plurality of trays, usually has three positions: an ejection position, a storage position, and a playing position. For example, as shown in Fig. 27, a stat force 502 and a disk drive unit 503 are provided in a disk drive device 501, and a fixed tray guide 504 is provided at the end thereof. It has been known. A plurality of trays 505 are placed in the stat force 502, and the stat force 502 itself can be moved up and down.

In the carousel method described above, the tray area becomes large, and there are restrictions on the design and design of the main body. In the case of the magazine type, the operability is poor because the disc is inserted into the cartridge once and then mounted on the mechanism. Furthermore, although the above-mentioned problems have been improved with the bank type, which trays are opened directly It is not clear whether it is playing or not (during play), and the operability and visibility are inferior. In addition, in the case of the independent tray type, each tray is thicker and independent trays are stacked one on top of the other, increasing the mechanical thickness.

 SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has as its object to provide a disk drive capable of reducing the size and thickness of the entire device.

 Further, in the conventional disk drive device 501, when the tray 505 is brought to the discharge position (open position), the engagement of gears and the like for driving the tray 505 is maintained and the tray 505 is moved. In this case, the length of the tray 505 in the moving direction becomes considerably larger than the diameter of the disk. That is, the interval 506 between the discharge position and the storage position in FIG. 27 is increased, and the depth dimension of the disk drive device 501 is increased.

 In this type of disk drive device 501, in order to facilitate the removal of the disk when it is opened, the disk is ejected forward at the discharge position. For this reason, the depth dimension tends to be further lengthened. In some cases, the depth dimension is shortened, but the disc is difficult to remove, the tray 505 is not fixed properly, and the gear meshing is unstable.

 SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and a disk drive device capable of shortening the depth dimension of a device and having the same quality and function as a long depth dimension. It is also intended to provide.

Disclosure of the invention

According to the first aspect of the present invention, in order to achieve the above object, In a disk drive with a mechanism for transporting a tray loaded with disks to a disk drive, the tray is configured to be separable into a main tray and a sub-tray, and the disks can be placed on a sub-tray. In addition, the sub-tray can be moved relative to the main tray, and a plurality of trays are arranged one above the other in the vertical direction. When the disk is stored, the tips of the sub-tray on the disk drive side are converged. ing.

 For this reason, only the sub-tray on which the disc is placed can be moved and brought to the disc drive. As a result, the moving part can be made smaller, and the device can be made smaller. In particular, when there are multiple trays, the drive location of the moving sub-tray can be set at an appropriate position, which increases the degree of freedom in design. In addition, by concentrating the destination of each sub-tray at a predetermined position, the space occupancy of the mechanically movable parts can be greatly reduced, and further miniaturization and thinning can be achieved. . Furthermore, when a so-called changer mechanism having a plurality of trays is used, the space occupancy of the mechanical moving parts can be significantly reduced, and the apparatus can be further reduced in size and thickness.

 Further, in another invention, in addition to the disk drive device of the above-described invention, the main tray and the sub tray are configured so that a part thereof vertically overlaps at a disk discharge position, and the disk is connected to the disk drive unit. When the disk is driven, the sub tray on which the disk is placed is separated from the main tray and moved to the disk drive.

In this way, at the disc ejection position, the main tray and a part of the sub tray overlap in the vertical direction, so that the disc can be reliably set on the sub tray. When driving a disc, the sub tray is Since the disk drive is separated from the in-tray, the movement of the main tray can be reduced even if the disk drive is located far away on the back side. Therefore, the size of the device can be reduced and the degree of freedom in design can be increased.

 Further, in another invention, in addition to the disk drive device of the above-mentioned invention, the sub-tray is arranged to be parallel to each other at a disk discharge position. Therefore, when setting or ejecting a disc involving a person, a natural feeling can be given as before, and the operability of the disc is improved.

 According to another aspect of the present invention, in addition to the above-described aspects, the disk drive unit has a holder for receiving the sub-tray and moving the sub-tray to a rotational position together with the disk on the sub-tray. For this reason, the sub tray separated from the main tray is held by the holder 1 and guided to the rotating position of the disk.

 Further, in another invention, in addition to the disk drive device of each of the above-described inventions, the holder is configured to be rotatable according to the inclination of the sub-tray. As described above, since the holder can be rotated in accordance with the inclination of the sub-tray, the sub-tray is reliably guided to the holder and held by the holder.

 Next, according to a second aspect of the present invention, in a disk drive device capable of pulling out a tray for mounting a disk, a guide portion for guiding and holding the tray is configured to be extendable and retractable, and the tray is ejected. The guide is longer when it is in the storage position than when it is in the storage position.

For this reason, when the tray is in the storage position, the guide portion can be shortened and downsized, and when the tray is moved to the discharge position, the guide portion becomes longer and the tray can be sufficiently held. As a result, the depth dimension of the device can be shortened, and the quality and function are equivalent to those with a long depth. It can be.

 Further, in another invention, in addition to the disk drive device of the above-mentioned invention, the inside of the case is constituted by a fixed guide guide and a slidable arm slidable with respect to the guide guide.

 For this reason, the tray is firmly guided and held in the storage position by the fixed guide. Then, at the discharge position, the slidable arm extends further forward from the guide guide to make the guide portion substantially long and securely hold the tray.

 Further, in another invention, in addition to the disk drive device of the above-mentioned invention, the tray is composed of two members that separate into a main tray and a sub-tray at a playing position, and when the tray is driven in the ejection direction, the main tray is moved. The slidable arm strikes the slidable arm and pushes the slidable arm toward the drawer side, and the rear end of the sub-tray is placed on the slidable arm. They are being drawn out.

 As described above, the tray is separated into the main tray and the sub-tray, and the slidable arm is pushed by the main tray, and the rear end of the sub-tray is placed on the slidable arm. And the sub-tray will be securely held.

 In addition, in the other inventions, in addition to the above-described inventions, when the guide portion becomes long, the leading end of the guide portion protrudes from the front end surface of the tray at the storage position. As described above, since the guide portion when it becomes longer protrudes from the tip of the tray at the storage position, the space can be considerably reduced in depth.

In another invention, a tray for loading a disc is pulled out. In the disk drive unit, the tray can be separated into a main tray and a sub-tray, and the length of the main tray extends to the playing position, and it moves from the storage position to the playing position. Has only a sub-tray, and the main tray and the sub-tray are guided by a guide unit and moved integrally to the discharge position.

 In this way, the length of the main tray that can be separated is set to the length that extends to the playing position, so that the rear end of the main tray must be fully inserted into the device even when the tray is in the discharging position. Can be. For this reason, it is not necessary to engage an extra gear or fix the position, and the apparatus can be shortened in the depth direction.

 Further, in another invention, in addition to the disk drive device of the above-mentioned invention, the guide portion is constituted by a fixed guide guide and a slidable arm slidable with respect to the guide guide.

 For this reason, when the tray is at the storage position, the guide portion can be shortened and downsized, and when the tray is moved to the discharge position, the guide portion becomes longer and the tray can be held sufficiently. As a result, the depth dimension of the device can be shortened, and the quality and function can be equivalent to those having a long depth. Moreover, the tray is firmly guided and held in the storage position by the fixed guide.

 Further, in the other inventions, in addition to the above-mentioned inventions, a plurality of trays can be arranged one above the other. For this reason, the depth dimension can be reduced without impairing the quality and function of the so-called changer mechanism. BRIEF DESCRIPTION OF THE FIGURES

 Hereinafter, a disk drive device according to an embodiment of the present invention will be described. The disk drive device 1 is a so-called changer mechanism that can store a plurality of magneto-optical disks and can play a predetermined disk from the stored magneto-optical disks.

First, the basic configuration and functions of this disk drive will be described with reference to the function explanatory diagrams of FIGS. 1 to 5. The disk drive 1 includes a disk discharge / storage unit 2 and a disk drive 3. As shown in FIG. 3, the disk drive 1 is roughly divided into a disk 5 for setting and discharging a disk 5. It operates so that it has three positions: an eject position, a storage position for storing the disc, and a playing position for playing the disc.

 The disk drive 1 has a plurality of trays 10 extending vertically. Each tray 10 is composed of two parts, a main tray 11 and a sub tray 12, which can be separated. The main tray 11 is arranged so as to surround the sub-tray 12, and the discharge end of the sub-tray 12 is detachably supported by the main tray 1. The disk 5 is placed on the sub tray 12. The sub tray 12 is integrated with the main tray 11 at the discharge position, and moves between the discharge position and the storage position together with the main tray 11. When moving from the discharge position to the storage position, the main tray 11 moves while maintaining a horizontal state, but the sub-tray 12 is guided by a chassis 13 whose fixed end on the playing position side is a fixed member. Move while moving. Since the chassis 13 is provided with a guide groove extending obliquely upward, as shown in FIG. 1, the sub-tray 12 is in a converged state in which the interval between the tips on the performance position side is narrowed.

Therefore, in the storage position, the main tray 11 is in a horizontal state, but the sub trays 12 on which the disks 5 are mounted are stored so that they are not parallel to each other. In this embodiment, as shown in FIG. 1, the information is stored so as to diagonally upward so as to gather in the uppermost sub-tray 12. That is, as shown in FIG. 4, at the discharge position, the main tray 11 and the sub-tray 12 are integrally and horizontally set together. Here, FIG. 4 (A) shows when the uppermost tray 10 is pulled out, FIG. 4 (B) shows when the center tray 10 is pulled out, and FIG. 4 (C) ) Indicates when the lowermost tray 10 is pulled out. Thus, each main tray 11 and each sub tray at the discharge position Both of them are in a horizontal state. In FIG. 4, the illustration of the disk 5 is partially omitted. FIG. 5 is a plan view of FIG. 4 (A) as viewed from above.

 The main tray 11 is in the horizontal position at the storage position in addition to the discharge position, but the sub trays 12 are at the horizontal position at the discharge position, as shown in Fig. 4. Except for the sub-tray 12, the other sub-tray 12 is stored diagonally so that the leading end of the playing side converges. For this reason, since the gap on the discharge side of each sub-tray 12 is determined by the interval between the main trays 11, a considerably large force The interval between the leading ends of the playing sides of each sub-tray 12 may be zero or close to zero. it can. Further, by forming the sub tray 12 thin, the overall thickness at the converging portion can be reduced.

 The sub-tray 12 in the storage position is moved to the disk drive unit 3 by a moving means (not shown) for moving the sub-tray 12. At this time, the sub-tray 12 is disengaged from the main tray 11 at the end on the discharge side, and is pulled out from the main tray 11 while being guided by the guide groove of the chassis 13.

The pulled out sub tray 12 enters into the holder 14 arranged in the disk drive unit 3. The holder 14 is supported so as to be rotatable about the fulcrum shaft 15 in the directions indicated by arrows g and h in FIG. For this reason, for example, when the sub-tray 12 in the lowermost tray 10 of the three trays 10 is transported to the holder 14, the sub-tray rotates in the direction of arrow c as shown in FIG. The inclination is set to be substantially the same as the inclination angle of the lowermost sub-tray 12. The angle of inclination of the holder 14 is set according to the sub-tray 12 to be conveyed, so as to match the angle of inclination of the sub-tray 12. When the subtray 12 on which the disc 5 is placed is returned to the original main tray 11 after the performance is finished, the holder 14 similarly rotates about the fulcrum shaft 15 and the holder 1 1 The sub-tray 12 in 4 is returned to the main tray 11 while being guided by the guide groove of the chassis 13.

 When the sub-tray 12 is transported into the holder 14, the fulcrum shaft 15 is lowered and the tip of the holder 14 on the storage position side is also lowered. That is, the storage position side of the holder 14 is slightly lowered, and the fulcrum shaft 15 side is largely lowered, so that the disk 14 is rotated in parallel with the disk drive unit 16 as a whole and the disk 5 is rotated. It will be mounted on the table 18 (see Fig. 2).

 The disc 5 is placed on the sub tray 12 except for the playing state. At the time of performance, it is held and fixed by the magnet of the clamper 17 in the holder 14 and the turntable 18 of the disk drive unit 16, and rotates together with the turntable 18.

 If the end button or the like is pressed after the performance or during the performance, the drive of the disk drive unit 16 stops, and then the holder 14 moves upward as a whole and corresponds to the predetermined main tray 11. To be inclined. After that, the sub tray 1 2 is engaged with the main tray 11 to be integrated. On the other hand, as shown in FIG. 2, the holder 14 is brought into a state where the turntable 18 of the disk drive unit 16 and the clamper 17 are engaged, and waits for the next instruction.

In this embodiment, a guide portion 13 for guiding and holding the tray 10 (specifically, fixed guide guides 61 and 62 to be described later and guide guides 61 and 62) will be described. The slidable arms 2 2 2, 2 2 3) are configured to be extendable and retractable, and the Is longer than in the storage position (see Fig. 3 and Fig. 5). That is, when the tray 10 is driven in the discharge direction, the main tray 11 hits the slidable arms 2 2 2, 2 2 3 and pushes the slidable arms 2 2 2, 2 2 3 to the drawer side. At the same time, the rear end of the sub-tray 12 is placed on the movable arms 2 2 2 and 2 2 3, and the main tray 11, the sub-tray 12 and the slidable arms 2 2 2 and 2 2 3 It is configured to be physically pulled out.

 The main configuration and main operation of the disk drive 1 have been described above. Next, a specific configuration of the disk drive device 1 having such a configuration will be described.

 The configuration of the disk drive device 1 is divided into a disk discharge / storage unit 2 and a disk drive unit 3 when divided from that position. On the other hand, in terms of functions, a tray unit consisting of a plurality of trays 10, a first drive unit for operating each tray 10 and a second drive unit for switching each tray are provided. It is mainly composed of a mechanical mechanism that operates in the drive unit and gives various movements to the tray 10 and the like, a chassis 13 and a disk drive unit 16.

 In this embodiment, the tray unit includes three trays 10 and a part of a chassis 13 that slidably holds each tray 10. The chassis 13 in the tray unit corresponds to a member fixed to both front sides of a resin chassis main body 190 (to be described later) constituting the chassis 13. Each tray 10 has a main tray 11 and a sub-tray 12 as shown in FIG.

The main tray 11 is made of a main tray 20 made of resin, a slider 21, a lock arm 22 that is rotatably mounted on the main tray 11, and a slideably mounted main tray 11. And an arm 23 for integrating the sub tray 12 with the main tray 11. The main tray 11 is further laterally attached to the lower front end of the main tray body 20, a first reinforcing bracket 24 for reinforcing the main tray body 20, and a slider 2 1 formed slightly longer than the slider 21. A second reinforcing member 25 for holding the main tray body 20 in cooperation with the main tray body 20 and a tension spring 26 for pulling the arm 23 to the center side. The members constituting the main tray 11 are integrated by a plurality of screws 27.

 The right side when viewed from the front of the main tray 11 is formed to be long so that the rear end thereof reaches the vicinity of the rear surface of the chassis main body 190 when in the storage position. This rear end position has reached a position beyond the large hole portion 198 of the chassis main body 190. On the other hand, when viewed from the front of the main tray 11, the left side is in the storage position, and the rear end extends to substantially the center of the large hole 198. Thus, even when the main tray 11 reaches the discharge position, the main tray 11 can sufficiently enter the apparatus main body, and can function as the tray 10.

 The sub-tray 12 has four bosses 31, 32, 33, 34 that slidably fit into the guide grooves of the chassis 13, two grooves 35, 36, and a front cutout. A notch 37, a rear notch 38, and a large notch 39 that is largely cut to prevent contact with the disk drive unit 16 are provided.

 Hereinafter, the structure of the tray unit and the related mechanical mechanism will be described together with the operation description. First, the open / close operation of the tray 10 will be described.

As described above, the slider 21 is sandwiched between the main tray body 20 and the second reinforcing bracket 25, and the rib 40 (see FIG. 7) Are guided by the grooves 41 (see FIG. 6) of the second reinforcing member 25, and are held so as to be able to reciprocate in the directions indicated by arrows a and b in FIG.

 The hole 42 of the locking arm 22 is rotatably supported by a boss 43 of the main tray body 20.

 The arm 23 is guided by the boss 20a and the guide wall 20b when the boss 20a (see FIG. 7) protruding from the main tray body 20 enters the center hole 44. In addition, the main tray body 20 and the second reinforcing plate 25 are held so as to be able to reciprocate in the directions indicated by arrows c and d in FIG. The arm 23 has one end attached to the main tray body 20 and the other end locked by a hole provided in an arm 45 protruding to the side of the arm 23 by a pull spring 26. It is always biased in the direction of arrow c.

 The sub tray 12 is positioned at the discharge position by fitting the grooves 35, 36 at the tip with the ribs 20c, 20c (see FIG. 7) formed at the tip of the main tray body 20. In the storage position, it is integrated with the main tray 11 and positioned.

 As shown in FIG. 8, the tip of the sub tray 12 enters between the main tray body 20 and the first reinforcing bracket 24 at the discharge position and the storage position, as shown in FIG. The tip portions 51, 51 provided on the sub tray 12 abut against the ribs 52, 52 provided on the main tray body 20, and are rotatable in the direction indicated by the arrow ef in FIG. . This rotation is smoother due to the provision of tapered surfaces 53, 53 that become thinner toward the tip on both sides of the tip of the sub tray 12, including the tips 51, 51. .

In the discharge position and the storage position, the triangular part at the end of the arm 23 enters the notch 37 at the front of the sub tray 12 and the slider 21 Are located so as to contact the rear end of the arm 23. Therefore, the arm 23 cannot escape from the notch 37, and the main tray 11 and the sub tray 12 are integrated.

 When the slider 21 moves from the state shown in FIG. 9 (A) in the direction of the arrow b to the state shown in FIG. 9 (B), the locking arm 22 rotates around the boss 4 3, The one-side boss part 54 enters the notch groove 55 provided in the slider 21. For this reason, the slider 21 is integrated with the main tray body 20 via the locking arm 22. This integration occurs when the subtray 12 comes to the storage position. In addition, the protrusion 56 at the rear end of the arm 23 comes into contact with the slider 21 by the movement of the slider 21 in the direction of the arrow b.

 As described above, the main tray 11, the sub tray 12, and the slider 21 are integrated at the storage position and the discharge position. The lower groove 57 of the second reinforcing plate 25 is guided and held by a rib 59 provided on a guide portion 58 which is a part of the chassis 13 (see FIG. 11). ).

As described above, in the storage position, the rib 40 of the slider 21 integrated with the sub-tray 1 enters the groove 41, and the tip of the sub-tray 1 2 And the first reinforcing plate 24, and the arm 23 is inserted into the notch 37 to be integrated and held with the main tray 11. In this storage position, each sub-tray 12 has left and right guides 61, 62, as shown in FIG. 10, with bosses 32, 34 behind the sub-tray 12 (details will be described later). Rise along the guide grooves 61a, 61b, 61c, 62a, 62b, 62c, and the inclination of the sub-tray 12 is changed to the guide grooves 61a to 62c. Is determined by each slope. In the storage position, Bosses 3 1 and 3 3 are held by guide guides 6 1 and 6 2, but are slightly protruded from guide guides 6 1 and 6 2 and are held by other holding portions of the train unit. You may do it.

 The bent portion 63 provided on the second reinforcing plate 25 fixed to the main tray main body 20 is for detecting that the tray 10 has reached the discharge position. That is, the bent portion 63 hits the projection 65 (see FIG. 11) of the first switch body 64 rotatably installed on the guide portion 58, and the first switch body 64 Is turned in the direction of arrow W in FIG. This rotation activates the first switch 66 to confirm that the tray 10 has reached the discharge position.

 The fact that the tray 10 is in the storage position is detected by a second switch body 67 rotatably mounted on the guide part 58. That is, first, the slider 21 is moved from the discharge position to the storage position by moving the slider 21 in the direction of arrow a in FIG. 6 by the driving force from the first motor 110 described later. . This movement is caused by the engagement of the locking arm 22 with the notch groove 55 of the slider 21. This movement is performed along the guide groove 68 of the guide portion 58. At the rear end of the guide groove 68, a tip groove 69 bent downward is formed (see a partially enlarged view of FIG. 11), and the other end boss portion 70 of the locking arm 22 guides. As a result, the locking arm 22 rotates downward. Therefore, the slider 21 is not integrated with the main tray body 20. As a result, Tray 10 apparently stops moving.

On the other hand, the slider 21 is further moved in the direction of arrow a by a first mode 110 described later. Due to this movement, the projection 71 of the second switch body 67 comes into contact with the slider 21 and the second switch body 67 rotates in the direction of arrow Y in FIG. Note that the second switch body 67 is It is constantly urged by the torsion spring 72 in the direction opposite to the Y direction. By the rotation of the second switch body 67, the projection 71 enters the notch groove 55 of the slider 21 and the second switch 73 is turned off. The on / off state of the second switch 73 detects that the tray 10 is at the storage position.

 In addition, the movement of the slider 21 in the direction indicated by arrow a after the main tray 11 is stopped enables the arm 23 to move in the direction indicated by arrow d in FIG. 6, and the sub-tray 12 moves relative to the main tray 11. It becomes detachable. The first switch body 64 and the second switch body 67 each have three protrusions 65, 71 so that they can operate the same with respect to the three trays 10, respectively. .

 Next, each configuration will be described together with the operation of moving the tray 10 between the storage position and the playing position.

 The following members are used to guide the tray 10 from the storage position to the playing position. That is, the holder 14, the holder tray 81 serving as support means for moving the holder 14 up and down, the sub-tray slider 82, the main tray slider 83, and the guide part 58 are arranged inside the guide part 58. A third switch body 86 that is rotatably disposed on a boss 85 on the rear side of the gear support 84, is sandwiched between the chassis 13 and the gear support 84, and the chassis 13 is A fourth switch body 87, which is rotatably arranged on a boss (not shown) on the front side of the third switch body, a third switch 88, which is operated by the third switch body 86, and a fourth switch body 88. A fourth switch 89 or the like that operates with the switch body 87 is used. Note that the third switch body 86 is biased toward the main tray slider 83 by a spring 86a.

Holder tray 81 is located on the right side when viewed from the front of holder 14 Have been. The sub-tray slider 82 is guided and held in the direction indicated by the arrow ab in FIG. 14 when the tip rib 92 of the holder tray 81 fits into the groove 91 (see FIG. 15). Further, a boss 94 bent at a right angle at the rear end of the main tray slider 83 is inserted and engaged with the hole 93 of the sub tray slider 82 (see FIG. 16). On the other hand, the main tray slider 83 is guided and held by a rib 95 of the gear support portion 84 so as to be able to reciprocate in the directions indicated by arrows a and b.

 The sub-tray slider 82, which can move integrally with the main tray slider 83 in the directions indicated by arrows a and b, moves while sliding below the holder tray 81. The holder tray 8 1 also rotates by the rotation of the holder 14. By this rotation, the engaged sub-tray slider 82 moves up and down on the boss 94 and faces the sub-tray 12 to be pulled out.

 The ribs 96 of the sub-tray slider 82 are arranged in the notches 38 behind the sub-tray 12 as shown in FIG. As described above, the sub-tray slider 82 is moved up and down by the rotation of the holder tray 81, and thereby enters the notch 38 of the sub-tray 12 to be pulled out. When the main tray slider 83 moves in the direction of arrow a, the sub-tray slider 82 moves at the same time, and the sub-tray 12 also moves through the sub-tray slider 82. At this time, the four bosses 3 1, 3 2, 3 3, 3 4 of the sub tray 1 2 are aligned with the groove 97 of the holder 14 (see FIG. 15) and the groove 98 of the holder tray 81 (see FIG. 15). ) Is held for guidance.

When the sub tray 12 is moved from the storage position to the playing position, the main tray slider 83 moves in the direction indicated by the arrow a, so that the ribs 99 of the main tray slider 83 are provided on the rear side of the apparatus. Sui The third switch 88 is turned on when the operating portion 101 of the switch body 86 is hit. With further movement in the direction of arrow a, the ribs 99 of the main tray slider 83 pass through the operating portion 101, and the third switch 88 is turned off (see FIG. 18). By this on / off, it is detected that the subtray 12 has come to the playing position, and the movement is stopped.

 On the other hand, when returning the sub-tray 12 from the playing position to the storage position, the rib 102 on the distal end side of the main tray slider 83 is operated by the operating portion of the fourth switch body 87 arranged at the front side of the apparatus. At 103, the fourth switch 89 turns on and then turns off (see FIG. 18). By this on / off, it is detected that the subtray 12 has been returned from the playing position to the storage position, and the returning operation is stopped.

 Next, the selection switching of the tray 10 and the disk clamp will be described. Prior to the description, the first and second drive units will be described. Both drive units are installed in a chassis main body 190 constituting the chassis 13 and are arranged below the entire apparatus. The schematic layout positions W1 and W2 of both drive units are shown. The arrangement position W1 indicates a position on the chassis main body 190, and the arrangement position W2 indicates a position on the gear support 84 fixed to the chassis main body 190.

 First, the first drive unit for performing the above-described operation will be described.

A first belt 1 1 2 wound around 1, a pulley gear 1 13 having a pulley around which the first belt 1 12 is wound, and a gear combined with a pulley gear 1 1 3 1 1 4 and gear 1 1 4 A large gear 1 15 coupled with the large gear 1 15 and a first gear 1 18 coupled with the first output gear 1 17 of the planetary mechanism 1 16 , A second gear 1 19 coupled with the first gear 1 18, a third gear 1 20 coupled with the second gear 1 19, and a fourth gear 1 coupled with the third gear 1 2 0 2 1, 5th gear 1 1 2 mating with 4th gear 1 2 1, 6th gear 1 2 3 mating with 5th gear 1 2 2, 7th gear mating with 6th gear 1 2 3 It is composed of a gear 1 24 and two engagement gears 1 26 and 1 26 that are combined with the second output gear 125 of the planetary mechanism 1 16.

 The planetary gear mechanism 1 16 includes an input gear 13 3 having an input section 13 1 and an output section 13 2, a first output gear 1 17, an internal tooth 13 4 and an external tooth 13 5. 2nd output gear 1 25 which has, 2 planetary gears 1 3 6 and 1 3 6 which are simultaneously engaged with output section 1 3 2 and internal teeth 1 3 4 and supports planetary gears 1 3 6 and 1 3 6 The two outputs 13 7 and 13 7 provided on the first output gear 11 17 and the input gear provided on the first output gear 11 17

A rotation center shaft 1 3 8 which fits in the center round hole of 1 3 3 and serves as a rotation center of the input gear 1 3 3 and the first output gear 1 1 7.

 The operation between the discharge position and the storage position of the tray 10 is performed by transmitting the drive of the first motor 110 to the slider 21. That is, the driving force of the first motor 110 is transmitted to the final seventh gear 124, and then the driving force is exposed to the side of the mechanical device shown in FIG. It is transmitted to 1 and further transmitted to the transmission gear 1 4 2. Transmission gear

14 2 is fitted to the rack 14 4 of the slider 21 (see FIGS. 6 and 7), and moves the slider 21 in the directions of arrows a and b.

The movement between the storage position of the tray 10 and the playing position is performed by transmitting the driving force of the first motor 110 to the main tray slider 83. You. That is, the driving force of the first motor 110 is transmitted from the second output gear 125 of the planetary mechanism to the engagement gears 126, 126. The engagement gears 12 6 and 12 6 are engaged with a rack 14 4 (see FIGS. 14 and 15) provided below the main tray slider 83. Arrows Operate in the a and b directions.

 Next, the selection switching of the tray 10 and the disk clamp will be described. Before describing this operation, the configuration of the second drive unit will be described.

 As shown in FIG. 20, the second drive unit section includes a second motor 150 arranged in front of the first motor 110 and a second motor 150 Pulley 15 1 fixed to the output shaft of the first pulley, a second belt 15 2 wound around the pulley 15 1, and a pulley 1 5 3 around which the second belt 15 2 is wound , Gear 15 4 mating with gear 15 3 with pulley, gear 15 5 mating with gear 15 4 and gear 15 mating with gear 15 5 having the same shape as gear 15 5 6, a gear 1557 engaging with the gear 1556, a gear 1558 engaging with the gear 1557, and a lift idler 1559 having a gear engaging with the gear 1558. You.

The lift idler 159 is combined with the rack 16 2 of the guide cam 16 1 (see FIG. 16). Therefore, the guide cam 161 can reciprocate in the direction indicated by the arrow ab by the rotation of the second motor 150. The two bosses 16 3 and 16 3 of the guide cam 16 1 fit into the grooves 16 4 of the guide portion 58 (see FIG. 11) and are guided. Further, a lift slider 1667 having a first cam hole 165 and a second cam hole 1666 is fixed to the guide cam 161, and both move integrally. The first boss 17 2 of the gear holder 17 1 (see FIG. 15) is inserted into the second cam hole 1 66. Also, the gear holder 1 7 1 has the first boss 1 As shown in Fig. 21, both the second boss 17 2 and the second boss 17 enter the elongated hole 1 75 of the reinforcing bracket 17 7 that is exposed and fixed on the side of the mechanical device. The guide is held so that only movement is possible. Gear holder 1 7 Shaft 1 in the upper two holes 1 1 6

77 is inserted, and the transmission gear 144 is arranged between the two holes 1776, 176. The transmission gear 14 2 moves up and down with the up and down movement of the gear holder 17 1, and engages with the slider 21 of the predetermined tray 10. That is, the g section of the second cam hole 1666 shown in FIG. 16 has a step shape, and the gear holder 17 1 and the transmission gear 14 2 are integrated into the step shape. It moves up and down along the second cam hole 166 to select and switch the tray 10 to be operated.

 On the other hand, in section f of FIG. 16 of the second cam hole 166, the height of the gear holder 171 does not change. The first boss 18 1 of the holder 14 (see FIG. 15) enters the first force hole 16 5 of the lift slider 16 7, and the first boss 18 1 further The guide groove 58 of the guide section 58 has entered the guide groove 18 (see Fig. 11) and is being guided.

 In addition, the second boss 1 that becomes the fulcrum shaft 15 shown at the end of the holder 14

83 and a third boss (not shown) on the opposite side are supported by grooves 1885 and 1886 of the lift holder 18 (see FIG. 15), respectively. The lift holder 18 4 receives the vertical movement when the groove 18 7 is engaged with the rib 19 1 (see Fig. 12) on the back of the chassis body 190, and the lift holder 18 4 The right end rib 1 8 8 is the groove 1 of the chassis body 1 90

Entering 9 (see Fig. 12), you are being guided up and down. The rear boss 1889a of the lift holder 1884 passes through the elongated hole 1993 on the rear surface of the chassis body 190, and is guided in the vertical direction.

The rotating cam part 200 is fitted with the chassis body 190 When the boss 194 enters, the boss can rotate around the boss g in the directions indicated by arrows r and s in FIG. The rotary cam portion 200 is provided with a groove 202 (see FIG. 16) whose position gradually changes in the height direction by rotation. The lift holder 18 is provided in this groove 202. 4 Front boss 1 89 b (see Fig. 15) is inserted. Therefore, when the rotation cam portion 200 rotates in the direction indicated by the arrow r, the front boss 189b is guided by the groove 202 and moves downward, so that the lift holder 184 descends. On the other hand, when the rotating cam portion 200 rotates in the direction indicated by the arrow s, the lift holder 184 rises.

 When the tray 10 is in the retracted position, the lift slider 167 is located on the rear side as a whole. When a performance instruction is input, the lift slider 167 is driven forward. As a result, the holder 14 moves upward, and the lift holder 18 4 also moves upward with the movement, so that the rotary cam portion 200 turns around in the arrow s direction. Thus, the first boss 18 1 of the holder 14 is positioned at the uppermost position of the first cam hole 16 5 of the lift slider 16 7.

At this time, when the guide cam 16 1 moves in the direction of the arrow a, the lift slider 1667 also moves in the direction of the arrow a. Then, the first boss 18 1 of the holder 14 moves downward along the first cam hole 16 5 of the lift slider 16 7. As a result, the holder 14 rotates in the direction indicated by the arrow h in FIG. 15 around the second boss 183 and the third boss on the opposite side as a fulcrum axis. The rotation angle is detected by detecting the step 204 (see Fig. 15) of the guide cam 161 with the fifth switch 205 (see Fig. 14), and the relative position therefrom is detected by the photointegrator 2. 06 is detected by detecting the five slits 2 07 of the guide cam 16 1, and is stopped at a predetermined rotation angle. By turning only the tip side of the holder 14, the holder 14 is brought to a position facing the sub-tray 12 which is brought to the playing position. Tray 10 to be played is selected according to the standby posture. Also, when the performance is completed, the same operation is performed, and by taking the standby posture according to the selected tray 10, the finished disk 5 and sub-tray 12 are transferred to the empty main tray 11. return.

 Even after the sub tray 12 holding the disc 5 is taken into the holder 14, the guide cam 16 1 advances in the direction of the arrow a. By this movement, the boss 208 of the rotating cam portion 200 engages with the curved groove 209 of the guide cam 161 and is guided, and rotates in the direction of arrow r in FIG. As a result, the lift holder 184 descends and the first boss 18 1 of the holder 14 is guided by the first cam hole 165 of the lift slider 167 to descend. As a result of the two downward movements, the entire holder 14 is moved to the disk drive unit 16 side from the position in which the sub-tray 12 is taken in, and the disk 5 is placed on the turntable 18.

 The operation of the tray 10 between the discharge position and the storage position, the operation of the sub-tray 12 between the storage position and the playing position, and the configuration related to the operation have been described above. Both operations are performed by the first drive unit. Switching between these two operations is performed using the planetary mechanism 116 of the first drive unit.

 The operation of the planetary mechanism 1 16 of the first drive unit will be described below with reference to FIGS. 19 and 22.

The rotation of the first motor 110 is transmitted to the large gear 115, and from the large gear 115 to the input gear 133 of the planetary mechanism 116. The rotation of the input gear 133 is transmitted from the output part 132 to the planet gears 135, 136. At this time, if the rotation of the second output gear 1 25 is stopped, The planetary gears 1 3 6 and 1 3 6 that engage with the internal gear 1 3 4 of the output gear 1 2 5 rotate and rotate along the internal gear 1 3 4 of the second output gear 1 2 5 Central shaft 1 3 Revolves around 8.

 [0 0 8 0]

 Since the planetary gears 13 6 and 13 6 are supported by the bosses 13 7 and 13 37 of the first output gear 11 17, the first output gear 11 It rotates in synchronism with the revolution of 36, 1 36. The rotation of the first output gear 1 17 is transmitted to the seventh gear 124, and then the slider 21 is moved via the transmission gear 142. Thereby, the operation between the discharge position and the storage position is performed.

 On the other hand, when the rotation of the first output gear 1 17 is stopped, the revolutions of the planetary gears 13 6 and 13 6 are stopped and only the rotation is performed. For this reason, the rotation of the input gear 133 is transmitted to the second output gear 125 through the planetary gears 133, 136, and rotates the second output gear 125. The rotation of the second output gear 125 is transmitted to the two engagement gears 126, 126, and the main tray slider 83 coupled with the engagement gears 126, 126 is moved. Drive and guide the sub tray 12 to the holder 14.

 As described above, two output gears 1 1 7 and 1 2 5 are provided for one input gear 13 3 to prevent rotation of one output gear. The configuration is such that the driving force of motor 110 is output, and the rotation of motor 110 is transmitted to two systems.

Next, the operation will be described in relation to the position of the lift slider 167. When the first boss 17 2 of the gear holder 17 1 is located in the section g shown in FIG. 16 of the list slider 16 7, the holder 14 is in the playing position. On the other hand, in this g section, the tray 10 that moves between the discharge position and the storage position is switched. First, the second morning The first cam 1721 and the lift slider 1667 integral therewith are driven so that the first boss 172 is at a predetermined position in the g section. If the rotation of the second output gear 125 in the planetary mechanism 116 is stopped during this g interval, the first output gear 117 rotates to move the slider 21. As a result, the tray 10 is discharged and stored. The rotation of the second output gear 125 is prevented as follows. The second output gear 125 is engaged with the engaging gears 126, 126, and the engaging gears 126, 126 are engaged with the main tray slider 83. The main tray slider 83 is at the unlock position when the disk 5 is in the storage position, and its tip abuts against the chassis body 190 as shown in FIG. On the other hand, the rear surface 94b of the rear end boss 94 faces the front surface 14a of the empty holder 14 (indicated by a two-dot chain line) in the playing position (down position). It is sandwiched between 190 and holder 14. Therefore, the rotation of the second output gear 125 is prevented.

 In addition, the sub tray 12 is taken into the holder 14, the holder 14 is lowered, and at the playing position of the disk 5 (indicated by a two-dot chain line), the main tray slider 83 is moved by a one-dot chain line in FIG. As shown in the figure, the rear surface 94b of the boss 94 faces the chassis body 190, and the front surface 94a of the boss 94 faces the rear surface of the holder 114. It is sandwiched between the holder 14 and the chassis body 190. For this reason, the second output gear 125 is prevented from rotating.

As described above, the movement of the tray 10 between the discharge position and the storage position can be performed both during the performance and when the performance is not performed. In any case, the holder 14 must be in the playing position (down position). Next, the lift slider 16 7 moves forward, and the first boss 17 2 of the gear holder 17 1 moves to the f section of the second cam hole 16 6 of the lift slider 16 7. The case where the first boss 18 1 of the holder 14 is in the h section of the first cam hole 16 5 shown in FIG. 16 will be described.

 In this h section, the sub trays 12 to be loaded and unloaded are switched. In this h section, the first boss 18 1 of the holder 14 has moved upward, and the tip of the holder 14 has come above the line L as shown in FIG. Therefore, the movement of the main tray slider 83 is not prevented. That is, the second output gear 125 can rotate, and the main tray slider 83 can move. However, for this purpose, it is necessary to prevent the rotation of the first output gear 117.

 Next, a configuration for preventing the rotation of the first output gear 117 in such a case will be described with reference to FIG. 24 and others.

 The rotation center hole 2 12 of the rack gear 2 1 1 (see FIGS. 15 and 16) is rotatably supported by the boss 2 13 of the guide portion 58 (see FIG. 11), and the torsion is provided. The spring is biased in the direction of arrow j in FIG. The boss 2 15 of the rack gear 2 11 1 contacts the innermost surface 16 7 a of the lift slider 16 7 while the first boss 18 1 of the holder 14 is in the h section, and the arrow j direction. Is prevented, and the rack gear 21 is rotated in the direction of arrow k.

When the rack gear 211 is rotated in the direction indicated by the arrow k, as shown in FIG. 24 (A), the pawl 216 of the rack gear 211 becomes the third gear 122 in the first drive unit. It jumps between the teeth of 0 (which is located on the gear support 84), thus blocking the rotation of the first output gear 117. For this reason, if the lift slider 167 is driven to the front side of the device, In this case, the operation between the discharge and storage of the tray 10 (opening and closing operations of the tray 10) is not performed, and the guide from the storage position of the sub tray 12 to the holder 114 and the reverse operation are performed.

 When the first boss 18 1 of the holder 14 moves to the section i in FIG. 16 when the lift slider 16 7 moves rearward, the lift slider 1 6 7 in contact with the boss 2 15 of the rack gear 21 1 As a result, the rack gear 211 rotates in the direction of arrow j as shown in FIG. 24 (B) by the urging force of the torsion spring 214, The rotation inhibition of the gear 120 is released. On the other hand, the holder 14 becomes the playing position, and the movement of the main tray slider 83 is prevented, so that the rotation of the second output gear 125 is stopped, and the opening operation of the tray 10 is performed again. The closing operation becomes possible.

 The specific configuration and main operation of the disk drive device 1 have been described above. Next, the configuration and operation that do not appear in the above description will be described.

 On each outer surface of the guide guides 6 1 and 6 2 shown in FIGS. 10 and 13, etc., there are six pairs of bosses 2 21 (see FIG. 13) on each side, 6 on each side. There are 12 in total. The boss 2 21 has three slidable arms 2 2 2 arranged on the left side of the guide guide 6 1 and three slidable arms 2 2 arranged on the right side of the guide guide 6 2. 2 2 3 is held and guided.

Specifically, each of the slidable arms 2 2 2 and 2 2 3 is provided with two long fitting holes 2 2 4, and the boss 2 2 1 is fitted into the fitting holes 2 2 4. . Thus, three left slidable arms 2 2 2 and three right slidable arms 2 2 4 are provided. One boss 2 2 1 fits into slot 2 2 4 Yes. Each of the slidable arms 222, 223 has a U-shaped cross section so as to fit into horizontal grooves provided above and below the bosses 221 of the guide guides 61, 62, respectively. I have. As a result, the slidable arms 222, 223 are guided and supported by the boss 221, and the horizontal grooves of the guide guides 61, 62, so that they can reciprocate.

 The function and operation of the slidable arms 2 2 2 and 2 2 3 are as follows. The slidable arm 22 and the guide guide 61 form one extensible guide, and the slidable arm 22 and the guide guide 62 extend and contract the other. A free guide is formed.

 When the main tray 11 moves in the discharge position (open) direction, the two bosses 3 2 and 3 4 at the rear end of the sub tray 1 2 are guided by the guide grooves 6 1 a to 6 2 of the guide guides 6 1 and 6 2. Try to drop from c. However, immediately before the drop, the left step 23 2 protruding inside the main tray 11 and the right step 23 3 protruding inside and downward (see FIG. 7) are slidable arms 2 2 2 and 2 2. The slidable arms 22, 22 and 23 move together with the main tray 11 in the open direction, while hitting the ribs 2 3 4, 2 3 5 (see Fig. 13) projecting outward from each of 23. To start.

As a result, the bosses 32, 34 of the sub-tray 12, the guide grooves 61, 62 of the guide guides 61, 62, and the guide grooves 23, 36 of the slidable arms 22, 22, 23 are moved from the guide grooves 61a, 62b. Go to That is, after the bosses 32, 34 of the sub-tray 12 are disengaged from the guide grooves 61a to 61c, the main tray 11, the sub-tray 12, and the slidable arms 2, 2, 2, 2 3 The four move together forward. At this time, the sub-tray 12 has its tip engaged with the main tray 11 and its rear end engaged with the slidable arms 22 2 and 22 3 to maintain a horizontal state. When the tray 10 is completely in the discharge position, the tips of the slidable arms 222, 223 are in the storage position. The other tray 10 protrudes from the front end face. As a result, the depth dimension can be significantly reduced.

 Also, when the disc 5 is placed on the disc drive unit 16 and the player is in the playing state, the two protrusions 2 41 1 and 2 42 (see FIG. 7) provided on the back of the One of the two discrimination switches 24 3 and 24 4 (see Fig. 13) is pressed. The switches 243 and 244 are arranged on a circuit board 246 attached to the base 245 at the rear end of the chassis main body 190.

 These two discriminating switches 2 4 3 and 2 4 4 can obtain various on-off combinations by removing or leaving one of the two projections 2 4 1 and 2 4 2 of the sub tray 12 . The combination of the on and off determines which sub tray 12 the disc 5 at the playing position belongs to, and determines which main tray 11 to return. That is, the address information of the sub tray 12 is obtained by the combination of the two discriminating switches 24 3 and 2 44 and the two protrusions 24 1 and 24 2.

In this embodiment, there are three trays 10, and the address information is set as follows. The judgment of the uppermost tray 10 (= sub-tray 1 2) is made by obtaining the ON signal from both discriminating switches 2 43, 244 while leaving both projections 241, 242. I have. As for the center tray 10 (sub-tray 1 2), the projection 2 42 is omitted. As a result, only the signal of the first discriminating switch 243 is turned on, and the second discriminating switch 244 is turned off, so that the tray 10 at the center is judged. In the case of the lower tray 10 (sub tray 12), the ON signal is obtained only from the second determination switch 244 by eliminating the protrusion 241. In the case of a four-stage tray 10, delete both projections 2 4 1 and 2 4 2, The type of sub-tray 12 can be easily distinguished.

 As shown in FIG. 14, the clamper 17 is composed of a resin clamper main body 247 and a donut-shaped magnet 248.

 Next, the outline of the operation of the disk drive device 1 configured as described above will be described again, although it partially overlaps with the above description.

 First, the operation of storing the disk 5 in the tray 10 will be described. An instruction to remove the predetermined tray 10 to the open position is given by a button or a remote controller. In response to this instruction, the control IC 266 operates the second motor 150 and moves the lift slider 167 slightly forward. The movement amount is adjusted according to the selected tray 10. That is, when the lower tray 10 is selected, there is almost no movement, and when the middle tray 10 is selected, the boss 17 2 of the gear holder 17 1 is moved to the middle of the second cam hole 16 6. Move forward until you reach the position. Also, when the uppermost tray 10 is selected, it moves greatly so that the boss 172 comes to the uppermost part of the second force hole 1666.

When the tray 10 is selected, the second motor 150 stops, and the control IC 266 drives the first motor 110. At this time, since the holder 14 is at the playing position, the movement of the main tray slider 83 is prevented. As a result, the second output gear 1 2 5 rotates , The slider 21 is moved in the direction of arrow b. As a result, the tray 10 (main tray 11 and sub-tray 12) moves to the discharge position.

 When the tray 10 comes to the discharge position, the first switch body 64 is operated to confirm that the switch is in the discharge position (storage position), and the control IC 266 switches the first motor 110 to the first position. Stop. In the discharge operation of the tray 10, the use of the slidable arms 222, 223 allows the guide 10 to be sufficiently held even if the guide guides 61, 62 are short. That is, the slidable arms 222, 233 slide forward in the middle of the discharging operation, and the tray 10 is maintained.

 After that, the disc 5 is placed on the tray 10 and a storage instruction is issued, the first motor 110 rotates in the opposite direction to the previous direction, and the slider 21 moves in the direction indicated by the arrow a. Then bring the tray 10 to the stowed position. In this storage position, the end of the sub-tray 12 converges, as shown in FIG. Then, the second motor 150 is rotated in the reverse direction, the lift slider 1667 is returned to the original position, and a standby state is set. The lift slider 167 may be left as it is without reversing the second mode 150.

 Next, the operation of setting the disk 5 to the playing position will be described.

When the play instruction of the disk 5 (= tray 10) to be played is selected by a button or a remote controller, the control IC 266 first operates the second mode 150, and the lift slider is operated as before. Move 1 6 7 forward. Due to this movement, the rotating cam portion 200 starts to act on the urging force of the click spring 25, and rotates in the direction indicated by the arrow s. For this reason, the lift holders 18 4 move up, and the rear end of the holders 14 moves to the top. However, the first boss 1 7 2 of the gear holder 17 1 In the position at the beginning of the f section of the second cam hole 16 6 of the rider 16 7, the first boss 18 1 of the holder 14 is in the i section of the first cam hole 16 5 Therefore, the tip of the holder 14 is below, and the holder 14 is greatly inclined.

 When the lift slider 1617 moves further forward, the first boss 181 becomes the h section of the first cam hole 165, and the first boss 181 rises in three stages. The position one step up from the bottom corresponds to the lowest tray 10, the next step corresponds to the middle tray 10, and the top one corresponds to the top tray 10. It will be.

 This position is detected by the photo interrupter 206 detecting the slit 207 of the guide cam 161. By this detection, the lift slider 1667 is stopped at a predetermined position, and the tray 10 (= disc 5) to be played is selected. At this time, the holder 14 becomes horizontal or inclined, as shown in FIG. 4, corresponding to the selected tray 10.

 At this time, the sub tray slider 82 engaged with the main tray slider 83 moves up and down together with the holder 14. The sub-tray 12 to be pulled out by this vertical movement is selected.

 Next, the first motor 110 starts to drive. At this time, the first output gear 1 17 is prevented from rotating. That is, since the first boss 18 1 of the holder 14 is located in the h section of the first cam hole 16 5, the boss 2 of the rack gear 2 1 1 is provided on the inner surface 16 7 a of the soft slider 16 7. 15 are in contact. As a result, the pawl 2 16 of the rack gear 2 11 fits into the third gear 120, and the rotation of the first output gear 117 is prevented.

Since the rotation of the first output gear 1 17 is blocked, the main tray slider 83 receives the rotation of the second output gear 125 and moves backward (as indicated by the arrow). a). As a result, the sub tray 12 engaged with the sub tray slider 82 is pulled out and taken into the holder 14. When the main tray slider 83 moves to the rearmost position, the third switch body 86 is operated to turn on and off the third switch 88. As a result, the control IC 266 stops the first motor 110. After that, the second motor 150 starts driving, and moves the lift slider 147 backward (in the direction of arrow a). Then, the guide cam 161, integral with the lift slider 1667, rotates the rotary cam portion 200 in the direction of the arrow r. Therefore, the entire holder 14 is lowered, and the disk 5 is placed on the turntable 18.

At the same time as the holder 14 falls, the sub tray 12 also falls. At this time, both or one of the two determination switches 24 3 and 24 4 is turned on depending on the presence or absence of the two protrusions 24 1 and 24 2 provided at the rear end of the sub tray 12. With this signal, the control IC 266 recognizes that the disk 5 to be played is the correct disk 5 and, after the performance is completed, the address information for selecting the tray 10 (main tray 11) to be returned. Use this signal as When the signals of the two discriminating switches 24 3 and 24 4 are generated, the control IC 2666 stops the second motor 150 and drives the spindle motor for the turntable 18 so that the disk 5 And play the information. When the disc 5 is returned after the performance or during the performance, the operation is performed by performing the operation reverse to the above-described operation. Note that it is possible to set a new disc 5 on the tray 10 in the playing state. This is because it is possible to drive the first motor 110 and move the slider 21 forward (in the direction of the arrow b) while driving the spindle motor for driving the disk. It is also possible to play another disc 5 continuously during or after the performance of one disc 5. The basic operation in this case is the same as described above, but after returning the sub-tray 12 with the disk 5 to the main tray 11, do not move the lift slider 16 7 In that it is located at a position opposite to the tray 10. As a result, the next subtray 12 can be immediately taken into the holder 14. However, the same operation may be repeated without omitting the operation.

 The above-described embodiment is a preferred example of the first aspect of the present invention, but various modifications can be made without departing from the gist of the present invention. For example, although the rear side of the sub tray 12 is converged upward, it may be converged downward or in the center. Further, a configuration may be adopted in which the rear end (back side) of the entire tray 10 is converged, instead of only the sub tray 12. In this case, the tray 10 is not separated, but the device can be made thinner.

 Although the disk drive unit 16 is fixed, the disk drive unit 16 may be a movable type. Further, instead of moving the holder 114 up and down, the holder may be moved in the horizontal direction as a so-called vertical die. In this case, the vertical movement, ascending, and descending in the description are each interpreted as horizontal movement.

In the above-described embodiment, the changer mechanism has a plurality of trays 10. However, the separation of the tray 10 and other configurations are also applied to a normal disk drive capable of inserting only one disk. be able to. Further, the present invention provides a compact disk, a laser disk, a mini disk, It can be applied to various disk devices such as digital video disks.

 Also in the second aspect of the present invention, various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the inside of the housing is provided with fixed guide guides 61, 62 and slidable arms 22, 22 slidable with respect to the guide guides 61, 62. Although it is composed of 3 and above, it is also possible to make the entire guide part moveable forward and backward, or to extend and retract freely by making a part of the bellows structure or the like.

 In addition, by making the length of the main tray 11 at least as long as it extends to the playing position, the size can be reduced and the tray can be held in a very stable manner. In terms of dimensions, it is preferable to increase the length from the rear end of the storage position by 50% or more (ratio to the diameter of the disk 5) in terms of miniaturization and stable tray holding. Also, when the tray 10 is set at the complete discharge position, the tip of the slidable arm 22, 22 23 protrudes from the front end face of the other tray 10 in the storage position. Even if this is not done, a considerable effect on miniaturization occurs.

 Further, in the above-described embodiment, the rear side of the sub tray 12 is converged upward, but may be converged downward or in the center. Further, a configuration may be adopted in which the rear end (back side) of the entire tray 10 is converged instead of only the sub tray 12. In this case, the configuration is not such that the tray 10 is separated, but the device can be made thinner.

Furthermore, although the disk drive unit 16 is fixed, the disk drive unit 16 may be a movable type. Further, instead of moving the holder 114 up and down, the holder 114 may be moved in the horizontal direction as a so-called vertical die. In this case, in the statement Up, down, ascending, and descending are each interpreted as horizontal movement. Industrial applicability
