Patent ID: 8371580

Claim:
A paper sheet processing apparatus which performs a skew correction of a paper sheet inserted and conveyed, comprising: an insertion slot into which the paper sheet is inserted; a skew correction mechanism which performs the skew correction of the paper sheet inserted from the insertion slot; a traveling route which extends from the insertion slot to an entrance of the skew correction mechanism and through which the paper sheet is conveyed; a conveyance mechanism which conveys the paper sheet provided between the insertion slot and the entrance of the skew correction mechanism, wherein: the skew correction mechanism comprises a pair of movable pieces which performs the skew correction of the paper sheet by regulating both side edges thereof as the paper sheet is squeezed, and the pair of movable pieces are positioned such that an open width between the pair of movable pieces is narrower than a width of a front end edge of the paper sheet when the front end edge of the paper sheet inserted from the insertion slot reaches the entrance of the skew correction mechanism, wherein: the pair of movable pieces respectively comprise: regulatory walls to regulate both side edges thereof as the paper sheet is squeezed; and touching faces at end portions of the regulatory walls on an upstream side, the touching faces of the pair of movable pieces are formed across the traveling route and define a vertical face substantially perpendicular to the traveling direction, and the conveyance mechanism conveys the paper sheet such that a front end edge of the paper sheet contacts the vertical face.
