A rotary storage unit includes a cabinet defining an interior within which a rotary storage member is located. A latch mechanism is mounted to the cabinet, and selectively engages the rotary storage member for maintaining the storage member in either an open position or a closed position. A motorized actuator arrangement is interconnected with the latch mechanism, for selectively moving the latch mechanism between a latching position and a release position. The motorized actuator arrangement includes a motor which imparts movement to an actuator rod interconnected with the latch mechanism, for moving the latch mechanism between its latching and release positions in response to axial movement of the actuator rod. The motor moves the actuator rod so as to return the latch mechanism to its latching position after expiration of a predetermined time delay. The actuator rod is interconnected with a spring which biases the latch mechanism toward its latching position, to provide a positive stop when the storage member is moved to a predetermined position relative to the cabinet. The motorized actuator arrangement is operable in response to operation of a hand-operable switch mounted to the cabinet.
