It is composed.

The slider 17 is provided with male positions 68 and 69 for limiting the lift distance of the disk separation unit 63 and switches 79 and 80 for limiting the lift distance of the clamper 74, respectively. As shown in FIG. 7 so that the lift state of the disc changer 2 can be visually seen from the outside, a light emitting element 18 is installed in front of the disc changer 2, and the player body 1 is provided. In front of the transparent window 81 for passing the light emitted from the light emitting element 18 is provided.

As shown in FIGS. 1 and 2, a plurality of tray position detection slits 82 are formed in the player body 1, and the position sensor 83 is formed in the body 21 of the disc changer 2. Is installed.

The multi-disc player according to the present invention configured as described above operates as follows.

First, when a user selects a desired disc tray from one side cabinet 6 in which a plurality of disc trays 8 are stored, the disc changer 2 is guided by the lifting motor 5 and the timing belt 4. ), The disc changer 2 is stopped at the disc tray withdrawal position by the tray position detecting slit 82 and the position detecting sensor 83.

In this state, the moving table 11 and the clamping lever rotating member 15 are advanced stepwise by the moving table and the clamping lever rotating member driving means 30, and are locked by the locker 9 at one side cabinet 6. The locking state of the disc tray 8 is released and the clamping lever 13 is rotated to a position where the disc tray 8 can be clamped.

That is, when the motor 38 as the drive means 30 is driven to rotate the drive gear 33 through the worm 37, the second gear part 35 and the second rack 32 of the drive gear 33 are rotated. The moving table 11 engaged by the first movement is first moved in the direction of arrow A, and the first gear part 34 of the drive gear 33 is idle, and then with the first rack 31 of the clamping lever rotating member 15. It is engaged to move the clamping lever pivot member 15 later in the direction of the arrow A.

Accordingly, as the moving table 11 and the clamping lever pivot member 15 are moved in stages, the release opening 12 installed in the moving table 11 pushes the locker (not shown) of the cabinet 6 to the disc tray 8. The locking state of the clamping lever rotating member 15 pushes the clamping lever 13 to push the clamping lever 13 to the position where the disk tray 8 can be locked.

Then, when the moving table 11 is moved to operate the first switch 25 installed in the changer body 21, the motor 38 is driven in the reverse direction.

Accordingly, as the drive gear 33 is rotated in the reverse direction, the first gear part 34 first engages with the first rack 31 of the clamping lever pivot member 15 to move the clamping lever pivot member 15 in the direction of arrow B. FIG. As it is, the clamping lever 13 is rotated by the elasticity of the spring 14 to clamp the disc tray (8).

Then, the second gear part 35 of the drive gear 33 is engaged with the second rack 32 of the moving table 11 to move the moving table 11 in the direction indicated by arrow B. As a result, the disc tray 8 ) Is withdrawn from the one-side accommodating portion 6 in a state of being clamped to the clamping lever 13.

Then, the disk separating means 60 is operated in the state where the disc tray 8 is withdrawn from the side cabinet 6 to lift the disc upward from the drawn disc tray 8 as shown in FIG. The disk clamping means 70 is operated to clamp the separated disk.

The disc separating means 60 is operated as follows.

First, the motor 67 is driven to rotate the worm wheel gear 65 through the worm 56, and the worm wheel gear 65 is rotated so that the screw portion 62 of the worm wheel gear 65 is rotated. As the elevating member 61 is screwed up, the disk separating portion 63 of the elevating member 61 lifts the disk upward and separates the disk from the disk tray 8.

At this time, when the elevating member 61 is raised and the end of the elevating member 61 operates the third switch 68, the motor 67 is stopped and the disk separating unit 63 is stopped at the raised position. When the member 61 is lowered and the end of the elevating member 61 operates the fourth switch 69, the motor is stopped to stop the disk separator 63 at the lowered position.

The disk clamping means 70 is operated as follows.

First, the motor 78 is driven to rotate the worm wheel gear 76 through the worm 77, and the worm wheel gear 76 is rotated to the threaded portion 72 of the worm wheel gear 76. As the screwed up / down member 71 is lowered, the clamper 74 elastically installed by the spring 73 on the lower portion of the elevating member 71 clamps the separated disk.

At this time, when the elevating member 71 is lowered and the end of the elevating member 71 operates the fifth switch 79, the motor 78 is stopped and the clamper 74 is stopped at the lowered position. When 71 is raised and the end of the elevating member 71 operates the sixth switch 80, the motor 78 is stopped and the clamper 74 is stopped at the raised position.

When the clamping of the separated disk is completed, the lifting motor 5 is driven to lower the disk changer 2, and the slider driving means 50 is driven to supply the clamped disk to one side regeneration unit 91. do.

That is, the motor 56 as the slider drive means 50 is driven to move the slider 17 in conjunction with the worm wheel gear 52 and the rack 51, and the slider 17 serves as the guide means 40. The guide rod 41 and the roller 42 move toward the one-side regeneration unit 91 to supply the clamped disc to the one-side regeneration unit 91.

And the disk separating portion 63 of the disk separating means 60 is in a lowered state, the clamper 74 of the disk clamping means 70 is raised, as shown in FIG. The disks accommodated in the accommodating parts 6 and 7 on both sides are clamped and supplied to the regenerating parts 91, 92, 93 and 94 on both sides, respectively.

As shown in FIG. 7, a light emitting element 18 is installed in the disc changer 2, and a transparent window 81 through which light emitted from the light emitting element 18 passes through the front of the player body 1 is provided. Since the user is able to see the moving state of the disk changer 2 from the outside, the visual effect can be obtained.

As described above, the multi-disc player of the present invention is configured to withdraw the disc tray from the storage cabinet, and to supply the disc from the withdrawn disc tray and to supply it to the reproducing unit in a state in which the disc is securely clamped. It is possible to prevent the detachment of the disk due to vibration or the like during use.
