- the clamp release lever uses a motor that feeds and operates the pickup as a driving source, but the motor for driving the pickup generally has a low torque. Yes, the clamp release lever can be rotated with a low-torque motor. Driving the clamp pawl in the retracting direction against the urging force of the lifting spring of the lifting member (disk clamp release direction) will result in insufficient torque, and the release of the clamp. There was a problem that the malfunction of the lever and the clamp claw was likely to occur.

There is an effect that it can be smoothly driven in the lifting direction and the retracting direction of the rotating / elevating member 13 with as much force as possible.
- the mode conversion motor 3 is not specially provided as a driving means dedicated to the clamp release levers 15, 16, the clamp release levers 15, 16 are attached to the turntable system mounting lever 22 or the swing lever 20. Compared with the case where a dedicated power motor is installed, the turntable transport system mechanism is not increased in size. Furthermore, since the clamp release levers 15 and 16 of the clamp control lever 19 only need to link the clamp release levers 15 and 16 and the rotating cam 30, the structure is simple and the turntable transport system mechanism There is an effect that it is possible to suppress the enlargement of the size. Further, since the clamp claw 12 is engaged with the rotation / lifting member 13 and is forced to rotate following the lifting / lowering operation of the rotation / lifting member 13, an operation failure of the clamp claw 12 may occur. It has a positive effect.
- the mode conversion motor 3 is restarted and the turntable 6 is stopped and held at the reproduction position.
- the clamp claw 12 drive system is rotated in the direction of the disc clamp in this state.
- the sensor is equipped with a motor control sensor, so there is no need for special operating mechanism parts. Can operate reliably and smoothly There is an effect that.
- the disk clamp device is such that the disk reproducing mechanism of the turntable mounting system is enlarged as in the case where the low-torque pick-up drive motor of the conventional example is replaced with a power motor. It has the effect of nothing, and is suitable for use in disc changers.
