Paper sheet processing device

Abstract

The purpose of the present invention is to provide a paper sheet processing device with a reduced number of components for detecting the presence of paper sheets on a conveyance path and which is capable of reducing costs. To achieve this aim, the paper sheet processing device has: an insertion port where paper sheets are inserted; a conveyance path along which paper sheets inserted into the insertion port are conveyed; sensors ( 10, 13, 32 ) that detect whether or not paper sheets are present on the conveyance path; a read unit ( 30 ) capable of reading inserted paper sheets; and a control unit that performs paper sheet detection processing whereby paper sheets present on the conveyance path are detected, based on the detection results of the sensors ( 10, 13, 32 ) and the read results of the read unit ( 30 ).

1 . A paper sheet processing device including:
 an insertion port through which a paper sheet is inserted, a conveyance path in which the paper sheet inserted into the insertion port is conveyed, a sensor for detecting the paper sheet in the conveyance path, and a read unit capable of reading the paper sheet inserted,   the paper sheet processing device, comprising   a control unit configured to execute paper sheet detection processing for detecting the paper sheet in the conveyance path, based on a detection result from the sensor and a read result from the read unit.   
     
     
         2 . The paper sheet processing device according to  claim 1 , wherein the control unit executes the paper sheet detection processing before the paper sheet is inserted into the insertion port. 
     
     
         3 . The paper sheet processing device according to  claim 1 , further comprising a conveyor configured to convey the paper sheet in the conveyance path,
 wherein when the paper sheet is detected by the paper sheet detection processing, the control unit performs the paper sheet detection processing again after the paper sheet is conveyed by the conveyor.   
     
     
         4 . The paper sheet processing device according to  claim 2 , further comprising a conveyor configured to convey the paper sheet in the conveyance path,
 wherein when the paper sheet is detected by the paper sheet detection processing, the control unit performs the paper sheet detection processing again after the paper sheet is conveyed by the conveyor.
