The device includes a drum (14) rotatably mounted in a frame for storing pieces of different sizes to be sorted out. Elements (20,21) on the drum, including openings of different dimensions pass pieces of different sizes respectively. Members (22) are disposed peripherally around the drum in radial alignment with those openings of one dimension for collecting pieces of a partic. size passing through the openings. A drive device (16) rotates the drum about its own axis to discharge the pieces out of the drum. The device has a separator for separating superimposed sorted-out pieces from each other. A magnetic or optical reader reads information recorded on sorted-out pieces, e.g. tickets, and rejects those pieces with defective information.
