Disk apparatus

A disk apparatus comprising:

• a frame having a guide;
• a motor;
• a disk tray adapted to be driven by the motor and carried into and out from the frame, the disk tray having an opening and a rack disposed on one side of the opening and meshed with a gear driven by the motor;
• a chucking mechanism adapted to grasp a disk carried into the frame by the disk tray, the chucking mechanism having a disk receiving member and a disk pressing member adapted to lift the disk set on the disk tray and press the disk against the receiving member;
• first buffer members made of vibration-proof rubber;
• a drive chassis disposed below the disk tray, the drive chassis having one end attached to the frame via the first buffer members and another end being swingable in vertical directions around the one end serving as a fulcrum, the drive chassis having a projection projecting from the another end;
• a disk scanning optical pickup disposed on the drive chassis;
• a cam plate having a com groove, the cam plate being movable in lateral directions at a position facing the another end;
• a second buffer member made of vibration-proof rubber and pressingly fit on the projection of the drive chassis;
• and
• a movable member attached to the another end via the second buffer member, the movable member adapted to be moved vertically as the movable member is guided along the cam groove,
• wherein the disk pressing member is disposed on the drive chassis and is passable the opening of the disk tray,
• the movable member has a substantially cylindrical shaft shape and externally fit on the second buffer member,
• the movable member is supported on the projection via the second buffer member without contacting the projection and the another end of the drive chassis,
• both side portions of the one end of the drive chassis is attached to the frame via the first buffer members,
• the guide of the frame extends vertically and assists a vertical movement of the movable member as the movable member is guided along the cam groove of the cam plate, and
• the motor is disposed on a portion of the frame so as to opposed to a side portion of the drive chassis that corresponds to a position on the disk tray in which the rack is disposed.
