PURPOSE:To fit a straight disk hub hole and a straight spindle head without pinching by making moving speed in horizontal and vertical directions of a disk lower than a fixed speed regardless of speed of opening and closing of a front door. CONSTITUTION:Immediately before a disk hub hole 9a is slid and guided by the tapered part 15c of a spindle head 15, a pin 25 attached to a pair of left and right side plates 3 interlocked with a front door 1 hits against a connecting member 11 of a buffer 12 and shock is absorbed by the buffer 12. Further, when a disk hub 9 is mounted on a lifting table 6, descending speed of the lifting table is relieved by a buffer 14 placed under the lifting table 16. An elastic member 4 is placed between the connecting member 2 of the front door and a pair of left and right side plates 3, and the force that closes the front door 1 is absorbed by the elastic member, then the pair of left and right side plates are operated by the repulsive force of the elastic member. Thus, pulling speed of a cartridge holder is made fixed at all times.
