Abstract

PURPOSE:To form a clamp mechanism of a disc player having a structure suitable for on-vehicle application by providing a torque via a plate spring provided to a drive section. CONSTITUTION:Even if the torque from a player main body delivered to a clamp plate 41 is fluctuated due to variance in the size of the constituting member of the player main body, since the variance is absorbed by the plate spring 51, a prescribed torque averaged nearly is delivered to the clamp plate 41. Since application of sudden shock to the clamp plate 41 is prevented, disadvantages such as damage to the clamp mechanism or malfunction is avoided.

Does a CD (compact disc) have sound? signal? It is an audio disc that is converted into a digital signal and recorded on a donut-shaped disc, and compared to a conventional LP record, it has a density of approximately 6 degrees of music information. Can be recorded. If it's EThl, the music signal is more than a minute on a 12cm diameter disc compared to a P record with a diameter of 3Dan? Is it to record it?
Moreover, since it is only for one side, it is possible to obtain multiple information signals from a small disk.

For small moving parts, the driving force from the player body is gear A2t.

If the disk is not loaded onto the disc player, the above-mentioned cross-shaped arm is located to the left of the arrow and the temporary spring 51 is inserted.
Since the clamp plate 4 is in contact with the clamp plate 4 and is biased by the clamp, the pressing portion 43 is in a raised position.

When the loading operation of Dinuku is started, the driving force from the player body is transferred to gears 32 and 33 at an appropriate timing.
.. 34' to the L-shaped arm A, and therefore the L-shaped arm A rotates in the right direction of the arrow and its tip 35.
A contacts and presses the temporary spring 51. If this pressing force is larger than the urging force of the spring, the clamp plate 4

In the series of operations as described above, in the present invention, the clamp g! A temporary spring 51 is installed in the drive unit 44 of [4], and the driving force from the player body is transferred from this temporary spring 51.
Therefore, the driving force from the player main body that is transmitted to the clamp plate 4 is
Even if there is variation due to dimensional variations in the constituent members of the player body, the variation can be absorbed by the leaf spring 51, so that a constant, approximately averaged driving force is transmitted to the clamp plate 4. Suddenly tl from the mouth to the clamp plate 41! Since it is possible to prevent L shock from being applied, is there any harm such as damage to the clamp mechanism or occurrence of malfunction? It can be avoided.
