Mechanism for positioning a tape cartridge

摘要

A biasing spring urges a lock member in a direction causing rollers to press a tape cartridge against reference surfaces of a tape drive device. An ejector lever retains the lock member in a cartridge processing release position. The ejector lever is shifted during cartridge insertion whereby the lock member moves to a second cartridge pressing position under the biasing spring to cause the rollers to press the tape cartridge against those reference surfaces.
