Abstract: An apparatus for sorting sheets includes a sorting section having boxes, a separating section, and a printing section, the latter two of which are respectively located on both sides of the sorting section. The separating section includes a separating mechanism for downwardly feeding out sheets in a constant gap system, a recognizing mechanism for scanning character information described on each sheet, a bar code scanning unit for scanning bar code information, and a conveying path of the separating section for conveying the sheets fed out of the separating mechanism. The printing section includes a printing mechanism for printing the recognized result as bar code information on the sheets, a verifying mechanism for verifying the printed result, and a conveying path of the printing section for feeding out the sheet on which the bar code is printed, to the sorting section.
