ABSTRACT:
A two-part tape cartridge locking mechanism for releasably locking a rotatable tape reel against rotation within a tape cartridge housing. A bias spring urges the tape reel against a major wall of the tape cartridge housing along an axis of rotation. A first part of the lock comprises a reel locking feature of the reel facing the major wall, and a housing locking feature of the major wall facing the reel locking feature, such that the reel locking feature engages the housing locking feature in a contact relationship when the tape reel is forced toward the major wall by the bias spring. A second part of the lock comprises a separately actuable reel lock mounted to the housing for holding the tape reel locking feature in the contact relationship with the housing locking feature until the reel lock is separately actuated away from the tape reel.
