Abstract

A bin for library articles and an automatic unloading system therefor includes a bin housing having a chamber defined by an uppermost housing plane and by opposing walls. A floor within the chamber has a top and bottom surfaces, and a plurality of cable apertures. A plurality of cables suspend the floor within the chamber, and are fixed at one end to the walls. The cables pass through the cable apertures in the floor, and are secured to a reversible cable driver which is, in turn, secured to the bottom surface of the floor. Clockwise rotational motive force of the driver causes the floor member to climb upward on the cables to the uppermost housing plane, while counter-clockwise rotational motive force causes the floor to descend downward from the housing plane. The automatic unloading system has a receiving frame for receiving the bin, and a frame tilting means for tilting the receiving frame when said bin is located thereon, such that articles present on the floor at the uppermost housing plane may freely slide off of the floor and away from the bin.
