Abstract: The present invention discloses an optical disk drive comprising a traverse, a traverse frame, a chassis and a stopper. The traverse frame is disposed on the chassis. And one end of the traverse is disposed on the chassis and the other end is disposed on the traverse frame. The stopper includes a protruded arm and an extended arm extended from the protruded arm. The protruded arm is integrated with the traverse by sheet metal forming and the extended arm is disposed above the traverse frame. The extended arm of the stopper is interfered with the traverse frame when a heavy shock is applied to the optical disk drive. Therefore, the optical disk drive including the stopper can prevent the separation between the traverse and the traverse frame without screws when a sudden hit is applied thereto.

Abstract: A disc cartridge loading apparatus of simple construction is disclosed which smoothly and securely loads and unloads a disc cartridge. The disc cartridge loading apparatus includes a main slider supported so as to be freely slidable on a chassis. A cartridge holder is supported between the side portions of the main slider so as to slide in upward and downward directions. In addition, a loading slider is provided which slides to and from the cartridge holder. The loading slider includes a hook portion which engages an engaging portion, provided in the side of a disc cartridge, when the cartridge is inserted into the cartridge holder. The loading apparatus is supported in a sub-chassis via damping members in a manner which prevents transmission of vibration from the sub-chassis to the loading apparatus. Further, during loading and unloading operation, engaging members are active to fix the positioning of the loading apparatus as a whole relative to the sub-chassis in the vertical, lateral and longitudinal directions so as to allow smooth and reliable loading and unloading of the disc cartridge.

Abstract: A disc clamping device of a compatible disc player, by which a mini disc or a compact disc can be selectively loaded on a single turntable clamps either the mini disc or the compact disc. The disc clamming device has a base plate including two side walls each having a reversed "L" shaped cut-out portion, a supporter extending upward, a clamper arm and a rotating body pivoting about a hinged shaft fastened to the supporter, an actuating rod projected through the lower end of the rotating body, a folded forward portion having a clamper mounted thereto; a moving plate having a arcuate portion defined in the lower corner of the rear end thereof, a rack gear, and a stepped cut portion formed in side thereof; a tray holder receiving a compact disc tray and a mini disc tray; and a loading device. Since the disc clamping device is simple in construction, stable operation is ensured and manufacturing cost is reduced. Clamping force of the clamper can be conveniently controlled by adjustment of the angle between the clamper arm and the rotating body.

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.
