Abstract

(57) [Abstract] [Purpose] To reduce the number of parts to reduce the production cost in a device that permanently ramps a disc such as a compact disc. [Structure] Notches are provided on the outer circumferences of the disc clamper 1 and the clamper cover 2, and after the disc cover 3 is inserted, the notches of the disc clamper and the clamper cover are eliminated to prevent the disc clamper and the clamper cover from coming off. I did it and deleted Clan Paosa.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disc device, and more particularly to a disc clamper mounting mechanism in a device having a disc (compact disc, CD-ROM disc, laser disc) such as a CD player.

[0002]

[Prior Art]

 A conventional disk clamper mounting mechanism is configured as shown in FIG. Immediately, the disc clamper 15 formed by a magnet is attached to the clamper cover 14, and is attached to the disc cover 12 by the clamper holder 13. The integrated disk clamper 15 and clamper cover 14 press the disk 5 from above, so that it does not come off when the disk 5 rotates, and stable rotation is obtained.

[0003]

[Problems to be solved by the device]

 In the conventional mounting method, the clamper 13 is required and the number of parts is 3, so that there is a problem that the cost of parts and the assembling cost are increased.

Therefore, it is an object of the present invention to provide a disk device having a disk clamper in which the parts cost and the assembly cost are reduced by reducing the number of parts.

[0005]

[Means for Solving the Problems]

 Therefore, in order to achieve the above-mentioned object of the present invention, a turntable, a disc cover having an engaging portion at a portion facing the turntable, and a clamper cover having an outer peripheral portion engaged with an engaging portion of the disc cover, A disc clamper disposed on the clamper cover is provided, an outwardly extending portion is formed on an outer peripheral portion of the disc clamper, and the extending portion is locked to a locking portion of the disk cover.

[0006]

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS.

FIG. 1A is a sectional view of the configuration of the present invention, showing a state in which the disc clamper 1 and the clamper cover 2 are attached to the disc cover 3.

In FIG. 1, the disc clamper 1 has four notches 6 on its outer circumference, and the notches 6 are inserted into locking portions of the disc cover 3, for example, the claws 4. After inserting, rotate by angle C. Similarly, the clamper car 2 having four notches 9 on the outer circumference is inserted into the disc cover 3. After the insertion, the disc clamper 1 and the clamper cover 2 are integrated by aligning the extending portions of the disc clamper 1, for example, the protrusions 7 (four places) and the notches 9 of the clamper cover 2 by rotating them. In the integrated method, the claws 11 of the clamper cover 2 are inserted into the mounting holes 8 of the disc clamper 1 and hooked and fixed as in the conventional case. In this way, when the disc clamper 1 and the clamper cover 2 are inserted into the disc cover 3 and then integrated, the cutout portions 6 and 9 of the disc clamper 1 and the clamper cover 2 respectively have protrusions 10 in the cutout portion 6. However, since the protrusion 7 is inserted in the notch 9, the notch of the outer shape is eliminated. Therefore, the disk cover 3 is prevented from being caught by the claw 4 and is prevented from coming off, and the same function as the conventional one can be obtained.

[0009]

[Effect of the device]

 As described above, according to the present invention, since the disc clamper and the clamper cover are integrated into the disc cover after they are inserted, the detachment can be prevented, and the clamper feeder used to prevent the detachment is not required. As a result, it has the result of reducing the parts cost and assembly cost.
