Abstract
A duplicate let off prevention device for sheets includes a first exit guide, a second exit guide which is spaced from the first exit guide at a distance that is larger than the thickness of one sheet and is smaller than the thickness of two sheets, and a pre-exit guide which is movably located adjacent a sheet storing device. Stacked sheets are segregated in a wedge-like configuration as they contact the respective guides. A stopper can stop the sheets when the pre-exit guide moves. The pre-exit guide is biased to exert a force to assist in the segregation of the sheets.
