Abstract

PURPOSE:To insert the spindle into the center hole surely even if the disc is located in a slightly deflected position, by evacuating the carrying mechanism after the spindle device is fitted into the disc center hole. CONSTITUTION:Carrying mechanism 3 is provided which includes holding materials such as a pair of rollers 23 and 30, which hold disc 50 between themselves and carry it, and has one or both of these rollers evacuated from the disc surface at the reproducing time. Spindle device 17a is provided which is evacuated from the carrying path of disc 50 for carrying of disc 50 and is inserted into the center hole of disc 50 at the reproducing time. Carrying mechanism 3 is evacuated after spindle device 17a is fitted into the center hole of disc 50. For example, stage 32 rises by release of excitation of plunger 35 due to the operation of position detecting switch S4, and turntable 17 and spindle 17a rise according to the rise of stage 32, and supporting plate 29 is turned to evacuate roller 30.
