Therefore, the disk cartridge 20 is detached without being hindered by the pressing member 58.
The holding arms 58b and 58c have a function of preventing the double mounting of the magneto-optical disk. That is, when the magneto-optical disk cartridge 20 is mounted, the holding arms 58b and 58c are located in the frame 54 as shown in FIG. positioned. For this reason, if an erroneous operation for mounting another magneto-optical disk cartridge _21-1 is mistakenly performed in a state where the magneto-optical disk cartridge is mounted, the flap 65 is moved in the initial stage of insertion. The magneto-optical disk cartridge _21-1 is provided with the holding arms 58b, 58b as shown by a two-dot chain line in FIG.
At the end of c, the magneto-optical disk cartridge _21-1 cannot be inserted any further, preventing double mounting of the magneto-optical disk cartridge.

Further, the leaf spring portions 61a and 61b are
The slider 55 may be formed integrally with a part of the slider 55 without being a separate member. The holding member 58
Is provided in the cartridge holder 56.
However, in this case, as shown in FIG. 19, the portion 125 for pressing the cartridge is located closer to the center, which is not preferable for stably pressing the cartridge.

The present invention can be applied not only to a cartridge containing a disk but also to a cartridge containing a tape.

As described above, according to the first aspect of the present invention, the operation of inserting the recording medium cartridge into the cartridge holder can be smoothly performed with a small force, and therefore, the operation of inserting the recording medium cartridge can be performed. The recording medium cartridge can be stably fixed to the mounting position without impairing the performance. In addition, with a recording medium cartridge holder
Since the mounting member is supported by the frame,
It does not move in the insertion direction of the media cartridge.
Of the recording media cartridge, for example, near the rear end in the insertion direction
Of the recording medium cartridge
Can be held down most stably.

According to the second aspect of the present invention, the cartridge
The slider that controls the movement of the rudder is a recording medium cartridge
Because it is a configuration that controls the movement of the pressing member, that is,
Since the slider controls the movement of both the cartridge holder and the recording medium cartridge pressing member, it is possible to optimize the timing for pressing the recording medium cartridge on which the recording medium cartridge pressing member is mounted with a simple configuration. Therefore, the operation of pressing the mounted recording medium cartridge can be stably performed.
