Abstract

PURPOSE:To prevent a disk from scratching even when the disk is brought into contact with a peripheral part by the external pressure since a disk player is dropped errorneously while loading the disk of the disk player which is ultra thin type and small-sized and the periphery of the disk is limited in terms of space. CONSTITUTION:The bottom face of the recessed part 10b of a lower cabinet 10 as a player body where a turntable placing to rotate a compact disk 3 to a central part is provided projectingly and a cover 13 to cover a driving mechanism to move back and forth an optical pickup and a spindle motor to drive the turntable 11, etc., are formed so as to be almost flush by making close to the bottom face of the disk 3 placed on the turntable 11 as near as possible. Further, the bottom face of the recessed part 10b of the lower cabinet 10 and the cover 13 are coated with the paint films A, B of the high elasticity paint of urethane system respectively.

However, in the above-mentioned conventional disc player, if the disc player is dropped with the disc 101 installed, the disc 101 may be damaged by the bottom surface of the recess 110b of the lower cabinet 110 or by the drive mechanism of the optical pickup 112. and turntable 1
The disk 101 is strongly contacted with a cover 113 that covers a spindle motor (none of which is shown) that drives the disk 101.
If the open button 114 is pressed during playback, the disk 101 will continue to rotate due to the inertia (inertial force) of the disk 101, and the disk 101 may hit the cover 113 etc. and cause scratches. there were. As a countermeasure for this, an adhesive tape-like cushioning material was pasted on the cover 113, etc., but it was unsightly, and there was a risk that dust etc. could accumulate on the adhesive part of the cushioning material and damage the disk 101. . Furthermore, in order to make the disc player thinner, the distance from the bottom surface of the disc 101 to the bottom surface of the recess 110b of the lower cabinet 110 and the top surface of the cover 113 is narrowed. It was difficult to paste due to space constraints. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a disc player that can prevent discs from being scratched when dropped, etc., and can further reduce the thickness and size of the disc.

According to the disc player 1 of the above embodiment, the lower cabinet 10 constituting a part of the player body 2
The bottom surface of the recess 10b of the lower cabinet 10 and the cover 13 are formed as close as possible to the disc 3 placed on the turntable 11 so that they are substantially flush with each other, and the bottom surface of the recess 10b of the lower cabinet 10 Since the cover 13 was covered with a urethane-based high elasticity paint, as shown in Figure 2,
The entire disc player 1 can be made much thinner. In addition, the disc player 1 with the disc 3 installed
Even if external pressure is applied to the disc player 1 due to accidental dropping of the disc 3, the disc 3 is protected by the coating films A and B of high elasticity paint and will not come into direct contact with the bottom of the recess 10b of the lower cabinet 10 or the cover 13. There is no disc 3
It is possible to reliably prevent damage to the Furthermore, while the disc player 1 is playing, the open button 14 of the upper cabinet 20 is pressed to open the upper cabinet 20, and the disc 3 continues to rotate due to the inertia of the disc 3.
Even if the disk 3 tries to hit the cover 13 or the like, the disk 3 is protected by the coating films A and B of the highly elastic paint and will not be damaged. Furthermore, lower cabinet 1
With the bottom surface of the concave portion 10b and the cover 13 as close as possible to the disc 3 placed on the turntable 11, during playback of the disc player 1, the surface of the disc player 1 is slightly deflected (for example, 0.5 mm). Even if the disk 3 is rotated in this state, the disk 3 will only hit the coating films A and B of the highly elastic paint, and will not directly rub against the bottom surface of the recess 10b of the lower cabinet 10 or the top surface of the cover 13.
