BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk player for playing a disk for performance or the like.

[0002]

2. Description of the Related Art When playing a disk such as a compact disk, a disk player which moves a tray carrying the disk and transports the disk to a reproduction position is well known. In such a disc player, the disc conveyed to the reproducing position is clamped and rotated by the clamper and the turntable, and the information is reproduced by the pickup.

[0003]

However, if the tray is misaligned during reproduction, when the clamp is released after the reproduction is completed, the turntable and the tray may come into contact with each other, or the disc may be carried on the tray. There was a problem that it was not carried accurately at the position.

[0004] It is an object of the present invention to solve the above-mentioned problems and to obtain a disc player in which the reliability of the clamp releasing operation is improved.

[0005]

SUMMARY OF THE INVENTION A disk player according to the present invention comprises: a disk transport means for transporting a disk to a playback position by moving a tray on which the disk is mounted; and a disk playback device for playing the disk at the playback position. Means, the disc reproducing means comprises a clamper, a turntable for clamping a disc together with the clamper, a pickup unit, a base for supporting the turntable and the pickup unit, and a clamp position for the turntable. Lifting means for raising and lowering the base to move between the non-clamp position,
The base is provided with a protruding piece for tray positioning that fits into a hole formed in the concave portion of the tray when the turntable is moved to a clamp position.

[0006]

In the present invention, at the same time as the clamping operation of the disk, the positioning of the tray carrying the disk and the base that supports the pickup unit and the turntable and moves up and down is performed. Therefore, the relative positions of the pickup unit and the turntable and the tray do not shift during the reproduction, so that the clamp releasing operation after the reproduction can be performed smoothly without any particular trouble. In the present invention, the positioning of the tray is released simultaneously with the operation of releasing the clamp of the disk. Therefore, after the clamp is released, it is possible to immediately shift to the operation of transporting the disk, and the operation as the disk player can be quickly performed.

At this time, the tooth portion 208c of the circular gear 23 rotates the right follow gear 206 to rotate the second pinion gear.
The lower tray 7 is moved from the playback position P to the standby position W via 22.

At this time, the lower sub-tray 16 does not move, and its front end 16a remains at the position R1. This state is the stage (c).

[Step (c) → (d)] When the upper tray 6 and the lower tray 7 are positioned at the reproduction position P and the standby position W, respectively, the meshing state between the teeth 208b and 208c and the follow gears 205 and 206 is established. Comes off. Immediately after this, the tooth portion 216 of the circular gear 23
And the tooth portion 401 of the circular cam 41 mesh with each other to rotate the circular cam 41 clockwise by a predetermined angle.
The guide pieces 407 to 409 of the float base 42 that engage with the shaped cam groove 405 move upward and move to the position v3 (FIG. 26). As a result, the pickup unit 404 (FIGS. 4 and 5) and the turntable 506 attached to the float base 42 also rise, and the disc 4 or 5 placed on the upper tray 6
Is held between the clamper 505 and the evening table 506 while being floated from the upper tray 6 to shift to a reproducing state.

At this time, the protruding piece 410 attached to the float base 42 is fitted into the positioning hole 105 of the upper tray 6 to keep the upper tray 6 stationary. This state is the stage (d).

[(D) → (e) stage] Further, the circular gear 23
When the is rotated, the tooth portion 208a of the circular gear 23 starts meshing with the follow gear 206, and moves the lower sub-tray 16 forward via the second pinion gear 22.

The lower sub-tray 16 moves with the lower tray 7 placed thereon, and its front end 16a moves from the position R1 to the position R2. Therefore, the lower tray 7 also moves from the standby position W to the eject position J. I do. However, this state in which the disk 4 or 5 of the upper tray 6 is in the reproducing state and the lower tray 7 is located at the ejection position J is the stage (e), and the upper and lower disks are compared with the original stage (a). 4 or 5 will be replaced.

In order to reverse the above procedure from step (e) to step (a), a signal for reversely rotating the motor 31 may be input by operating the switch group 14 (FIG. 1).

In the above embodiment, the case where the tray on which the disc is placed is of two upper and lower stages has been described. However, the present invention provides a disk player having a plurality of trays of three or more stages and capable of continuous playing. Also applicable to
