PROBLEM TO BE SOLVED: To make it possible to eject a foreign matter or a non-fixed type disk by transporting a disk between a 1st position where the disk can be driven by a drive unit in a case and a 2nd position where the disk can be ejected from the case and continuously driving the disk for an arbitrary period of time at the time of transporting it from the 1st position to the 2nd position. SOLUTION: A circuit board is mounted with a microcomputer 79 and a driving circuit 80 thereon and based on the input state of signals from each detection switch and an inject switch 4, the driving of a loading motor 24 is controlled by the microcomputer 79 through the driving circuit 80. When the disk is transported, the inject switch is pressed down by the microcomputer 79 and when it is made ON once but immediately made OFF, the microcomputer 79 applies a negative voltage to the loading motor 24. When continuously pushing on the inject switch, the eject operation is successively operated to make each mechanism perform through the microcomputer 79 and the driving circuit 80.
