Paper sheet handling apparatus

摘要

A paper sheet handling apparatus includes: a paper sheet insertion unit into which a plurality of paper sheets are inserted; a first plate provided at the paper sheet insertion unit; a second plate provided at the paper sheet insertion unit and that holds the plurality of paper sheets in a sandwiching manner with the first plate; a pressure distribution sensing sheet provided to at least one of the first or second plate and that senses a pressure distribution on the plurality of paper sheets held by the first and second plates; and a controlling unit that determines the presence/absence of a foreign body according to the pressure distribution sensed by the pressure distribution sensing sheet.

1. A paper sheet handling apparatus comprising:
a paper sheet insertion unit into which a plurality of paper sheets are inserted;
a first plate provided at the paper sheet insertion unit;a second plate provided at the paper sheet insertion unit and that holds the plurality of paper sheets in a sandwiching manner with the first plate;a pressure distribution sensing sheet provided to at least one of the first or second plate and that senses a pressure distribution on the plurality of paper sheets held by the first and second plates; anda controlling unit that determines a presence/absence of a foreign body according to the pressure distribution sensed by the pressure distribution sensing sheet, whereinthe controlling unit
detects an abutment region between the pressure distribution sensing sheet and the paper sheets from among the pressure distributions sensed by the pressure distribution sensing sheet, anddetermines the presence/absence of a foreign body using different standards for pressure abnormality in a central region of the abutment region and for pressure abnormality in a peripheral region of the abutment region in a manner such that a foreign body is more readily sensed in the peripheral region than in the central region.
