Another object of the present invention is to provide an inclined arcuate sidewall disposed on one side of the central depression so that the inclined arch surface of the inclined arcuate sidewall can help the compact disc to be quickly placed on the turntable spindle.

Another object of the present invention is to provide a laminate structure for mounting several small precision PCBs.

According to a preferred embodiment of the present invention having this purpose, there are several obvious advantages as follows.

1. The movement of the elastic fixing member allows the user or repairer to quickly assemble or disassemble the base and cabinet.

2. The gap between the longitudinally formed through hole of the cabinet and the upper surface of the elastic rubber member gives a good impact resistance to the rotating compact disk, so that the laser member of the present invention can read the stored information from the rotating compact disk. Keeps the emitted sound or music completely.

3. The eye shield member can prevent the user's eyes from being damaged from the laser member when the user looks through the viewer of the present invention to check the rotation state of the compact disk.

4. The inclined arch surface of the inclined arcuate sidewall of the present invention in the depression of the base can help the compact disc to be quickly placed on the turntable spindle without any friction with the surface of the compact disc.

5. The laminate structure is formed at the bottom of several columns arranged under the base. The pillars disposed below one side of the base have a plurality of grooves disposed below them for mounting the plurality of PCBs. The bottom of the other columns below the opposite side of the base can also mount the opposite side of the plurality of PCBs. A plurality of washers may each be inserted into each space between opposite sides of the plurality of laminated PCBs.

The stacked structure underneath the base of the base allows the mounting of a plurality of small precision PCBs instead of large PCBs, thereby allowing the compact disc player of the present invention to save a lot of space.

6. The compact disc player of the present invention with small volume makes it possible to reduce production cost, delivery cost and damage in delivery, whereby the compact disc player of the present invention has market competitiveness.
