PURPOSE:To attain simply and surely the control of high accuracy by providing a disk loading mechanism, two rack member driving the clamper mechanism, a transmission mechanism having a driving source giving selectively a driving torque to the two rack members, and a turning mechanism elevating and descending a turning tray for loading disk of the disk loading mechanism in interlocking with the one rack member while being turned. CONSTITUTION:In the clamper mechanism 18, when a tray 20 reaches a disk drive position and is stopped, a reducer gear 27 drives a lock gear 28 via a moving rack 39, a clamper lever 45 is operated and a disk 33 is pressed into contact with a turntable 34. Since the constitution of the clamper mechanism 18 is simplified, it is miniaturized and since the disk 33 is loaded onto the turntable 34 in a prescribed state, simple and sure control is attained. Since the disk loading mechanism is formed that the operation is satisfied by using reducer gears 25, 27 to which the drive torque is transmitted serially from the same power source and having different gear ratio, the constitution of the loading drive system is simplified and smooth control is attained by ensuring the operation of each part. |
