Abstract: A locking mechanism for the reels of a tape cassette includes a pair of reel locks which are rotatable between reel engaging and disengaging positions and a spring on each of the reel locks for returning the reel locks to their reel engaging positions. The spring includes a resilient arm having one end which is formed in integral, one-piece relationship to a bushing of each of the reel locks, the bushing permitting rotation of the reel locks. The resilient arm of each reel lock extends at an angle to each of the reel locks and the other end of each arm is free and unattached and the arms slidably engage stationary portions of the cassette housing to cause the spring return action.

Abstract: A latch for the door of a tape cassette includes a latching member for latching the door closed. The latching member is mounted for rotation about an axis between latching and unlatching positions. A spring, including a resilient arm, urges the latching member toward the latching position. One end of the arm is formed in integral, one-piece relationship to the latching member and the opposite end of the arm is free, but bears against a wall in one of the cassette housing halves on the side of the latching member in the direction of rotation toward the unlatching direction. In one embodiment of latch, the end of the arm which is attached to the latching member is located between the axis of rotation and the opposite free end of the arm.
