PROBLEM TO BE SOLVED: To provide a player with built-in disk drive in which hand-closing can be performed without adding an expensive component. SOLUTION: A control part 60 has an A/D input port P in which voltage generated at terminals of a loading motor 78 is reduced with the prescribed rate by dividing resistors R1, R2 and to which the voltage is applied. When a disk tray 10 is fully discharged, voltage applied to the A/D input port P is obtained at interval of 20 ms and compared with a prescribed threshold value, when the obtained voltage is the prescribed threshold value or less, count value is cleared, on the contrary, when the obtained voltage is larger than the prescribed threshold value, the count value is increased. Then, when the count value is five or more, the control part 60 outputs a control signal to a driver circuit 88 to drive the loading motor, so that the disk tray 10 is housed.
