PURPOSE:To attain simply and surely the control of high accuracy by providing the 1st transmission gear system driving the going and coming of a loading mechanism at a prescribed reducer ratio, the 2nd transmission gear system driving a clamper mechanism with a gear reducer ratio larger than that of the 1st transmiffion gear system and a drive source connected in series to the two transmission gear systems. CONSTITUTION:The disk loading mechanism is formed so that the operation is satisfied by using reducer gears 25, 27 in which the driving force from the same operation power is transmitted in series and having different gear reducer ratio. Thus, the constitution of the loading drive system is simplified. further, each part of a fixed rack 38 and a moving rack 39 is operated by using the reducer gears 25, 27 driven by the same drive system and having different reducer ratio and the reducer gears 25, 27 and the tooth part 393 of the fixed rack 38 and the moving rack 39 are meshed at the same time so as to transfer the torque mutually. Thus, the control of the dirve system is simplified surely. |
