ン量を小さくする１＝めのものである。When attempting to play an arbitrary disc 2, the motor control unit 8 first determines the position of the target disc 2, and then uses the potentiometer 9 to determine the current position of the deck unit 5.
Tighten. When the two positions are apart from each other by more than a certain value, a high-speed rotation command is given to the transfer motor 6 to move the deck part 5 at high speed, and when the distance between the two is less than a certain value, the transfer motor 6 is instructed to rotate at a low speed. A rotation command is given to move the deck part 5 at low speed. This is the 1st value that reduces the amount of overrun when moving at high speed and stopping.

制御部８の動作のフローヂャートを第４図に示す。Next, the operation will be explained. When attempting to play any disc 2, the motor control unit 8 first selects the target disc 2.
, and then determine the current position of the deck section 5 from the output of the potentiometer 9. When these two positions are apart from each other by more than a certain value, the high-speed transfer motor 10
When a rotation command is given to move the deck part 5 at high speed, and the distance between the two becomes less than a certain value, or when it is less than a certain value from the beginning, a rotation command is given to the low-speed transfer motor 1 and the high-speed transfer motor 0 is moved. A stop command is given to the deck part 5.
move at low speed. The speed ratio between high speed and low speed can be set by changing the reduction ratio of each gear V box 12, so by setting a small reduction ratio on the high speed side and a large reduction ratio on the low speed side, it is possible to set the speed ratio at high speed. Moreover, accurate transfer can be performed. When the difference between the position of the disc 2 and the position of the deck part 5 becomes small enough for the loading mechanism 3 to take out the disc 2, the low-speed transfer motor 1 is stopped, and the loading mechanism 3 takes out the disc 2. The storage container 1
