Claims

[Scope of utility model registration request]

A loading member moves to pull out a magnetic tape from a loaded tape cassette and attach it to a tape guide drum containing a rotary head over a desired range for recording and/or reproduction. Alternatively, in the playback device, the loading member is connected via an elastic member, and includes a ring member that rotates to move the loading member, a drive gear for rotating the ring member, and a drive gear that rotates the ring member. a rotation transmission mechanism that has a gear body that is in mesh with (or non-mesh with) the drive gear, and that transmits the rotation of the drive gear to the ring member while the gear body is in mesh with the drive gear; With the ring member rotated to the final position and the loading member pressed against the stopper by the elastic force of the elastic member, the rotation transmission mechanism is operated to disengage the gear body from the drive gear. and a rack member that engages with the gear body that has been brought into a non-meshing state with respect to the drive gear by the switching mechanism to limit rotation of the ring member via the rotation transmission mechanism. A loading member locking mechanism for a magnetic recording and/or reproducing device, wherein the rack member is configured to be displaceable in a direction away from the gear body and biased by a spring in a direction to mesh with the gear body.
