Paper sheet conveyor and paper sheet conveyance method

摘要

A paper sheet transport apparatus (10) includes transport member that is slidable along the widthwise direction of a transport path (11) (e.g., a drive roller (36) and a driven roller (38)), and a paper sheet detection unit (inlet-side paper sheet detection sensor (70)) that is arranged on an upstream side of the transport member in the paper sheet transport direction along the transport path (11) and detects the position of the paper sheet in the widthwise direction of the transport path (11). A control unit (80) calculates an amount of movement of the transport member based on the position of the paper sheet in the widthwise direction of the transport path (11) detected by the paper sheet detection unit and a previously set predetermined position of the paper sheet in the widthwise direction of the transport path (11).

1. A paper sheet transport apparatus that transports a paper sheet along a transport path, comprising:
a transport member that is slidable along a widthwise direction of the transport path and transports the paper sheet along the transport path; a paper sheet detection unit that is arranged on an upstream side of the transport member in a paper sheet transport direction along the transport path and detects a position of the paper sheet in the widthwise direction of the transport path; a control unit that calculates an amount of movement of the transport member based on a position of the paper sheet in the widthwise direction of the transport path detected by the paper sheet detection unit and a previously set predetermined position of the paper sheet in the widthwise direction of the transport path, and performs a control so as to slide the transport member by the calculated movement amount when the paper sheet is transported by the transport member; and a first fixed transport member and a second fixed transport member arranged on an upstream side and on a downstream side of the transport member in the paper sheet transport direction, the first fixed transport member and the second fixed transport member being firmly fixed and transporting the paper sheet along the transport path, wherein the paper sheet detection unit also detects a skew amount of the paper sheet, and the control unit performs a control so as to slide the transport member along the widthwise direction of the transport path so as to correct a skew state of the paper sheet based on the skew amount of the paper sheet detected by the paper sheet detection unit when the paper sheet is transported from the first fixed transport member to the transport member or when the paper sheet is transported from the transport member and received by the second fixed transport member.
