FIG. 7 shows a state in which the control board 2 is at the position shown in FIG. 3. As is clear from FIG. 7, the first movable board 9 is located above the position shown in FIG. The second movable substrate 16 is located at a position slightly displaced, and the second movable substrate 16 is displaced below the uppermost non-operation position. When in this state, the turntable 10
Are in a state of being inserted into a center hole S formed in the disk D, and the clamp member 17 is in a state of approaching the disk D. In such a state, the second movable substrate 16 is formed by the difference in shape between the inclined portion 21c of the third control groove 21 and the inclined portion 22c of the fourth control groove 22 formed on the control substrate 2. Becomes inclined.

When the control board 2 is further displaced in the direction of arrow A from such a state, the control board 2 is moved to the second position shown in FIG.
However, when the motor is displaced to the second position, the rotation of the motor stops, and the displacement force on the control board 2 disappears. When the control board 2 moves to such a second position,
The first control pin 12 and the second control pin 13 attached to the first moving board 9 are provided with the second holding portion 14b and the second control groove 15 of the first control groove 14 formed on the control board 2. Is supported by the second holding portion 15b.

Accordingly, in this state, the first movable substrate 9 is in the uppermost operating position, and the second movable substrate 9 is in the second position. The moving substrate 16 is in the lowermost operating position. The state shown in FIG. 8 shows such a state. As is apparent from FIG. 8, the disk D is placed on the turntable 10 and is also clamped by the clamp member 17. Become. Then, the disk D is pressed and held on the turntable 10 by the attraction force of the magnet 18 incorporated in the clamp member 17 to the turntable 10. Therefore, when a reproducing operation is performed in such a state, a rotation driving operation of the turntable 10 by a rotation operation of the spindle motor 11 is performed,
Since the rotation driving operation of the disk D is performed,
The playback operation of the disc player can be performed.

The mounting operation of the disc D at the reproduction position is performed as described above, but the first moving substrate 9 and the second moving substrate 9 are moved along with the displacement operation of the control substrate 2 from the first position to the second position.
The displacement operation of the moving substrate 16 is performed in the vertical direction.

As described above, the mounting operation of the disk D to the reproduction position is performed. Next, the discharging operation of the disk D will be described. When the operation button for ejecting the disc D is operated while the disc D is mounted in the above-described reproduction position, the motor is rotated and the second position of the control board 2 is shifted from the first position to the first position. Is performed. The direction of displacement of the control board 2 from the second position to the first position is in the direction of arrow B, and is opposite to the direction of arrow A described above.

When the control board 2 is displaced in the direction of arrow B, the control board 2 is displaced in the order of FIGS. 3, 2 and 1 from the state shown in FIG. First
The positions of the moving substrate 9 and the second moving substrate 16 are displaced in the order of FIGS. 7, 6 and 5 from the state shown in FIG. When the control board 2 is displaced to the position shown in FIG. 1, that is, the first position, the turntable 10 and the clamp member 17 are separated from the disk D as shown in FIG. Therefore, in such a state, when the drive mechanism for displacing the tray from the reproduction position to the attachment / detachment position is operated, the tray can be moved to the attachment / detachment position, and the disc D can be taken out from the tray.

As described above, the operation of ejecting the disk D at the reproducing position is performed. However, when the second moving substrate 16 is displaced from the state shown in FIG. 8 to the state shown in FIG. The substrate 16 is inclined due to a difference in shape between the inclined portion 21c of the third control groove 21 and the inclined portion 22c of the fourth control groove 22 formed on the control substrate 2. When the second movable substrate 16 is tilted by such an operation, the second movable substrate 16
The clamp member 17 supported by the moving substrate 16 is also inclined. Since the detaching operation of the clamp member 17 from the turntable 10 is performed while tilting, the detaching operation of the magnet 18 from the turntable 10 can be performed with a small force. Therefore, the displacement operation of the control board 2 from the second position to the first position can be performed with a small driving force.
