As described above, the pull-out of the recording tape and the pull-back which is the reverse operation thereof are performed by the same pull-out members 17 to 21 for the recording tapes of any cassettes.

Further, in the above-described embodiment, the position of the reel driving member is moved to compensate for the difference in the distance between the end surface provided with the opening of each cassette and the reel. The same position is also applied to the recording tape (for example, the drawing member 17 to
No. 21 inactive state) and ends at that position, so that when the recording tape is pulled out and pulled back, complicated functions for position adjustment such as ejecting or pushing down the above holders are unnecessary, This not only simplifies the configuration of the entire apparatus, but also has the effect of being simple and reliable in operation.

Further, such a movement of the reel driving member must be locked when the first unit 3 or the second unit 4 is mounted, but the movement lock of the reel driving member and the locking after the mounting of each unit. Since it is interlocked with, at least when the tape is pulled out, it is safe to insert and remove the unit and move the reel, and by making it possible to perform these with a common member, The configuration of the device itself becomes very simple.

Since the invention of this application has the above-mentioned structure and operation, when the tape holders of different sizes are used by being exchanged for the common recording or reproducing apparatus based on this, Since there are few components used only for most of the built-in devices, there are few restrictions on the shape between a plurality of tape holders that accommodate recording media, and the operation is simple and reliable. .

In particular, even if a plurality of tape holders are exchanged and used, a common member can be used as the reel drive mechanism and the recording medium pull-out mechanism, and the intervals between them can be automatically adjusted according to the mounting of the tape holders. Since the intervals are adapted to the tape holder, these series of operations can be reliably performed.
