Abstract

A thin sheet-sorting apparatus, wherein straps fastening bundles of, for example, one hundred bank notes are taken off and put in a sorting card-issuing device, which in turn impresses prescribed data associated with the bundles of bank notes on the straps and also digital data representing the impressed information on sorting cards; for each lot of, for example, one thousand bank notes the bank notes are stacked in batches of 100 together with the corresponding sorting cards in the feed section of the sorting apparatus; the bank notes and sorting cards are separated in the first sorting device into a first group consisting of fit bank notes including damaged ones and a second group consisting of unit bank notes and sorting cards; counting is made of both groups to ascertain whether the total number of the fit bank notes including the slightly damaged or unsoiled ones still available for recirculation and the unfit bank notes for each of the batches was a prescribed number, i.e. 100 or whether the coincidence between the total number of the sheets of each batch set in said feed section and that of the sheets of the first and second groups was obtained; straps fastening the bundles of bank notes in which unfit bank notes were found are taken out to read out the items of data impressed on said straps, for example, the names of persons who initially strapped such defective bundles of bank notes.
