Claims

[Scope of utility model registration request]

The lock release button is provided on a cassette holding member that is driven to move between a tape cassette attachment/detachment position and a loading position of a magnetic recording/reproducing apparatus, and is engaged with a lock release button provided on a tape cassette mounted on the cassette holding member. Accordingly, in the cassette lid unlocking mechanism for unlocking the cassette lid of the tape cassette, a rotary member having a lock release member that can be engaged with a lock release button of the tape cassette attached to the cassette holding member is provided. It is characterized in that it is rotatably disposed on a cassette holding member, and as the cassette holding member moves, the rotating member is rotated to engage the lock release member and the lock release button. Cassette lid lock release mechanism.
