Abstract

PURPOSE:To ensure the clamping by a clamper means by using an elastic spring loaded between a retainer and a support so as to absorb a disk pressing force of the clamper means. CONSTITUTION:The clamper means consists of a retainer 4 supported onto a base 17 and a support 15 loaded freely movably vertically to the retainer 4, and an elastic spring 18 is loaded between the retainer 4 and the support 15. A drive means drives the clamper means and the clamper means fixes a disk onto a turntable 2, then the disk pressing force of the clamper means by the drive means is absorbed completely by the elastic spring 18 provided between the retainer 4 and the support 15. Thus, the clamper means fixes surely the disk onto the turntable 2.

(B) Conventional Technology Conventionally, in a disc clamping device used in a device for enjoying music etc. using a disc, as shown in Fig. 1, the mounting table (21) for conveying the disc is usually a turntable (21).
2) It is supported higher, and when loading the disc, the presser means (2)
4), the mounting table <21) was pushed down below the turntable (22), and the disk was held on the turntable <22). Clamping of the presser means (24) is usually carried out using a dedicated motor or plunger, which not only requires a relatively large amount of electric power, but also requires many moving parts and switches such as timing limit switches. As the number increased, the failure rate was also high.

(E) Embodiment In the disc mounting apparatus of the present invention, the clamper means is equipped with a presser and a holder. Then, by using a member that has a dogleg shape on the side and pivots the bent part as this holding tool, and providing a timing bin on the timing gear to push down one end of the holding tool, that timing gear can be used for other drives. For example, by receiving power transmission from a moving device for the mounting table, etc., the device can be simplified and failures can be reduced. This device prevents the holding means from coming off a predetermined position before the timing bin reaches the holding means, or the timing bin from moving too far, in the following manner. That is, since the above-mentioned substantially dogleg-shaped presser is rotatably supported, in this device, the rotating shaft of the timing gear is used as a stopper of the presser, and the timing gear locks with the timing bin by a predetermined rotation. By providing a hook on the holding tool, the timing gear is prevented from turning too much.
