The above-mentioned transportation lock screw of the prior art is troublesome because the optical pickup is fixed by mounting the screw by lifting or reversing the set, and the screw mounting position at the time of designing. Had to consider. The optical pickup protector made of paper is difficult to position on the tray because it is made of paper when it is mounted, and it is necessary to attach the tape to the tray with tape to fix it, which is very time-consuming, and is difficult to re-transport. Since the reattachment was made of paper, it was difficult for the user to store it again and re-transport it.
In addition, increasing the strength of the optical pickup and its drive unit so as to withstand impact, especially as in an LD player, when the weight of the optical pickup becomes large, the drive unit becomes very large, and the holding function used. There is a drawback that the material becomes heavy and the structure becomes complicated. Therefore, an object of the present invention is to solve the problems of these conventional techniques,
An object is to provide an optical pickup fixing device capable of easily fixing the optical pickup and its drive unit.

In a reproducing apparatus for mounting and loading a disc on a stepped portion of a tray of the reproducing apparatus and engaging the turntable through the notch portion of the tray to reproduce the disc, a hole for engaging the turntable. And an adapter having a mounting portion to be mounted on the stepped portion of the tray and an optical pickup protection portion that protrudes from the notch portion of the tray and prevents sliding of the optical pickup, is mounted and loaded on the tray. At this time, the hole is engaged with the turntable, and the optical pickup protection unit prevents the optical pickup from sliding.
