The function of holding the cover 23 in the open state and the function of positioning the drive motor 71 can be provided to the function 21, and the number of components can be reduced.

The recording and / or reproducing apparatus according to the present invention has been described in detail using the recording and / or reproducing apparatus 20. However, the present invention is not limited to this, and a recording and / or reproducing apparatus for recording and / or reproducing a disk cartridge containing a disk-shaped recording medium such as an optical disk or a magneto-optical disk in a cartridge, or a disk unit Of course, the present invention can be applied to a recording and / or reproducing apparatus such as a disc player apparatus for recording and / or reproducing.

[0044]

The recording and / or reproducing apparatus according to the present invention comprises an elastic member provided with a guide hole and attached to the main body, and an engaging piece engaged with the guide hole and provided on the lid side. . And. The engagement piece is engaged with the guide hole in a state where the lid closes the recording / reproducing section, and when the lid is rotated in the opening direction to open the recording / reproducing section, the engaging piece projects to the side edge of the guide hole. The elastic member is elastically displaced and moved out of the guide hole, and is abutted against the outer edge of the elastic member to hold the lid in an open state. As described above, since the recording and / or reproducing apparatus has a simplified configuration and does not need to perform a caulking step as in the related art, the assembling work can be facilitated and the entire apparatus can be reduced in size. Can be achieved.
