7. EXPLANATION OF MECHANISM
(1) Tray loading mechanism When the tray loading motor rotates counterclockwise, motion is transmitted to the slide rack D through the intermediate gear 1 A , intermediate gear 2 B and tray pinion C , resulting in insignificant motion in the arrow direction. The slide rack is linked with the operating chassis. It lowers the pickup mechanism. The protrusion of slide rack E is linked with the tray through the groove at the rear side of tray, so that the tray is pushed ahead a little. When the tray is pushed out, the slide rack is disconnected from the tray pinion, and at the same time the gear at the rear side of tray is connected with the tray pinion, and the tray is pushed ahead. When the tray is pushed out fully, the slide rack moves further in the arrow direction through the groove at the rear side of tray. The tray position detection switch F is turned on, and the tray loading motor stops. When the tray closes the operation is as follows. If the tray OPEN/CLOSE button or tray is pressed and the detection switch is turned off, the tray loading motor rotates clockwise, so that the tray is retracted. When the detection switch is turned on again, the tray loading motor stops.

(2) Pickup feed mechanism When the sled motor A rotates, the rack C moves through the sled pinion B so that the pickup D is moved to the internal or external periphery. When it is moved to the innermost periphery, the position detection switch E is pushed by the rack, so that the position of pickup is initialized. Pickup (3) Disc rotation mechanism The spindle motor is used to rotate. IC701 is used to control. When the spindle motor is replaced, replace the spindle unit.
