Therefore, in such a state, the first turning support member 5 on which the first control pin 8 is formed and the second turning support member 9 on which the second control pin 11 is formed.
Is held in a first position, which is a lower position.
Therefore, the movable plate 2 supported by the first rotation support member 5 and the second rotation support member 9 so that the rotation position is controlled is in the inoperative position displaced downward.

When the tray is in the loading / unloading position, the disc is placed on the loading portion formed on the tray, and then the tray is stored, the tray is displaced to the reproducing position by the rotating force of the electric motor. Can be When the tray is slid to the reproduction position, the drive gear 12 is rotated counterclockwise with the displacement operation, and the drive gear 12
The rotation control member 13 formed with the teeth 13C in a state of being meshed with is rotated from the first position shown in FIG. 1 to the second position shown in FIG.

It comes into contact with the portion 16B.

FIG. 3 and FIG. 4 show a state in which such a displacement operation is performed.
The first rotation support member 5 on which the control pin 8 is formed and the second rotation support member 9 on which the second control pin 11 is formed are in a state of being held at the second position, which is the upper position. . Therefore, the movable plate 2 supported by the first rotation support member 5 and the second rotation support member 9 so that the rotation position is controlled is in the operation position displaced upward.

When the movable plate 2 is displaced to the operating position,
The disc is placed and held on the turntable 4 provided on the moving plate 2 by the action of the clamp member, and the optical pickup or the like is arranged at a position where the reproducing operation can be performed. Therefore, in such a state, when the reproducing operation is performed, the rotation driving operation of the turntable 4 by the rotation operation of the electric motor is performed, and the rotation driving operation of the disc is performed. You can do it.

As described above, the operation of mounting the disk at the reproduction position is performed. Next, the operation of ejecting the disk will be described. When the operation button for ejecting the disc is operated while the disc is in the state of being mounted at the above-described reproduction position, the rotation driving operation of the electric motor is performed, and the drive gear 12 is driven.
Is rotated clockwise. When the drive gear 12 is rotated in the clockwise direction, the rotation control member 13 having the teeth 13C meshed with the drive gear 12 is moved from the second position shown in FIG. The first shown
Is rotated to the position shown in FIG.

When the above operation is performed, the lower surface of the second tilt control unit 16 is moved to the fourth state.
A force acts on the control pin 18 to displace the fourth control pin 18 downward. Therefore, even when a clamping means requiring a large force to detach the turntable and the clamp member is used, the detaching operation can be reliably performed.

FIGS. 1 and 2 show a state in which such a displacement operation has been performed. When in this state, the first operation is performed.
The first rotation support member 5 on which the control pin 8 is formed and the second rotation support member 9 on which the second control pin 11 is formed are in a state of being held at a first position, which is a lower position. . Therefore, the movable plate 2 supported by the first rotation support member 5 and the second rotation support member 9 so that the rotation position is controlled is positioned at the inoperative position displaced downward.

When the movable plate 2 is rotated to the inoperative position, the engagement between the turntable 4 and the clamp member is released, and the center portion 4A of the turntable 4 is released.
The state of engagement between the disk and the center hole of the disk is released. After the release operation is performed, if a rotation operation of the electric motor for displacing the tray to the mounting / dismounting position is performed, the tray is displaced to the mounting / dismounting position, and the operation of taking out the disk is performed.

From the second position of the rotation control member 13 to the first
The rotational displacement operation of the movable plate 2 from the operation position to the non-operation position by the rotational displacement operation to the position is performed by the engagement displacement force of the first tilt control unit 15 with respect to the third control pin 17 and the second tilt control unit 16 Of the movable plate 2 or the biasing force of the spring, the third control pin may be used in this case. 17 and the fourth control pin 18 are not always necessary.
