ABSTRACT:
A disk player for loading and unloading a pair of disks while closing and opening a door to the disk player under control of a single motor capable of rotating in both the clockwise direction and the counterclockwise direction. During rotation in one direction of the motor a plurality of connecting gears transmit the power of the motor to a driver for the pickup, which reads the information on the disks, and to moving rack. The moving rack causes rotation of a cam gear for disengaging a disk holder and rotation of a fitting for slightly opening the door. This causes a gear rack to engage the plurality of connecting gears to thereby open the door fully so that the pair of disks can be inserted or removed from the door. After the disks are inserted in the door the motor reverses direction and pulls the door shut by reverse operation of the components used in the opening of the door.
