Abstract:
1. A paper handling apparatus, comprising: a first path that guides paper to a processing tray; a second path in which the paper is set aside, said second path branching from said first path; a transportation unit that transports the paper in one of a first direction toward the processing tray and a second direction opposite to the first direction; a branching unit that, when the paper is transported in the second direction, leads the paper to the second path; a single paper detection unit provided at a position upstream of the branching unit; and a control unit that determines timing in which the paper is transported in the second direction based on an output of the paper detection unit, and causes the transportation unit to transport the paper to the second path; wherein the paper handling apparatus sets aside a preceding sheet of the paper in the second path by reversing the preceding sheet with the attitude thereof kept unchanged, and transports the set-aside preceding sheet of the paper with a following sheet of the paper, the control unit determines timing in which the paper is transported in the second direction based on timing in which the single paper detection unit detects a back end of the preceding sheet and wherein the control unit determines timing in which the preceding sheet and the following sheet are superposed and transported together toward the processing tray based on timing in which the front end of the following sheet is detected.
