Claims

[Scope of utility model registration request]

In a cassette adapter to which a small-sized tape cassette is attached and used in a recording/playback device for a larger-sized tape cassette, there is a loading operation for pulling out the tape from the tape cassette, and a loading operation for pulling out the tape from the tape cassette. a loading mechanism that performs an unloading operation that rewinds the rope and the ink mechanism; a clutch mechanism that controls the rotational force direction of the rotating portion of the rope and the ink mechanism in either the loading operation direction or the unloading operation direction; and a tape cassette. a tape reel drive means for driving the tape reel; a take-up idler mechanism that is always in an interlocking relationship with the rotating part of the loading mechanism and can be freely engaged and detached from the tape reel drive means; During the loading operation, the clutch mechanism is controlled so that the rotational force of the rotating part of the loading mechanism rotates only in the loading direction, and the interlocking relationship between the take-up idler and the tape reel drive means is released, and the unloading is performed. During operation, the clutch mechanism is controlled so that the rotation direction of the rotating part of the loading mechanism is rotated only in the unloading direction, and the switching is such that the interlocking relationship between the take-up idler and the tape reel drive means is maintained. A cassette adapter characterized by comprising a mechanism.
