ABSTRACT:
A sold out detector for an article storage and dispensing device includes a detecting plate which is pivotally supported on the device and normally pushed toward one side plate of the device by the stored articles and an empty switch controlled by the movements of the detecting plate. A movable element extends within the clearance between the side plate and the detecting plate to contact with the plates. The movable element is operatively connected with a drive source to enable the rotating motion of the drive source to transmit movement to the detecting plate through the movable element. As a result, frozen water which tends to fill the gap between the side plate of the device and the detecting plate easily falls away.
