Abstract
Abstract Drive mechanism is provided for moving a storage assembly in either direction. The drive mechanism includes a solenoid and a movable plunger. The plunger pivotally mounts an actuator arm which engages and moves the storage assembly. A magnet is positioned on the actuator arm. The magnet attempts to align itself with the magnetic field of the solenoid. The aligning force swings a drive end of the actuator arm to one side or the other depending on the polarity of the voltage applied to the solenoid.
