Disc reproducing apparatus with motor base bearing system

A disc reproducing apparatus comprising:

• a motor for driving the disc;
• a turntable coupled to a motor shaft of the motor;
• a motor base for mounting the motor;
• a chassis for supporting the motor;
• a motor base bearing system, including a member, mounted on the chassis, defining a surface, the motor base being in direct contact with and sliding along said surface, for bearing a flapping of the motor base around a second axis on the motor base intersecting at a right angle a trace of a beam spot of an optical pickup in a direction normal to a disc placed on the turntable in parallel with a disc surface;
• a device for holding the motor base on the motor base bearing system;
• and
• an adjusting member mounted on the chassis for adjusting the flapping attitude of the motor base around the second axis.

• a chassis for supporting the motor;
• a motor base bearing system including guiding members, mounted on the chassis, defining a surface, the motor base being in direct contact with and sliding along said surface, for bearing a pendulum swing of a motor base above the chassis around a first axis along a trace of a beam spot of an optical pickup in a direction normal to a disc placed on the turntable and a flapping of the motor base around a second axis on the motor base intersecting at a right angle the beam spot trace in parallel with the disc surface;
• a device for holding the motor base on the motor base bearing system;
• a first adjusting member mounted on the chassis for adjusting the pendulum swing attitude of the motor base around the first axis;
• and
• a second adjusting member mounted on the chassis for adjusting the flapping attitude of the motor base around the second axis.
