Abstract

Abstract An apparatus for classifying a sheet-like written piece in the designated pocket corresponding to the classification code indicated on the surface of the written piece selected from among the pockets provided on a written material passageway, which comprises a device for supplying data designating the pocket to which the written piece is to be distributed; a device for furnishing data on the current position of the written piece when it passes during transit on the passageway through one of a plurality of detectors provided thereon; a counting device for counting the length of time required for the written piece to cover a distance between the adjacent ones of said detectors; a memory device consisting of at least as many storing sections as written pieces jointly traveling on the passageway at a given time, each of said sections being stored with data designating the pocket in which the written piece is to be received, data on the current position of the written piece and a counted time required for the written piece to cover a distance between any two adjacent ones of the plural detectors; a data-replacing device for successively replacing data on the current position of the written piece while traveling on the passageway and, when a prescribed relationship is detected to exist between the pocketdesignating data and data on any current position of the written piece, guiding the written piece into the designated pocket; and a device for taking proper measures to cope with the abnormal condition when a signal denoting an excess time count over a prescribed level is detected.
