Paper sheet processing apparatus

Abstract

A paper sheet processing apparatus including a plurality of transport units connected in a transport direction to which a paper sheet is transported, each of the plurality of transport units including a paper sheet detection sensor configured to detect presence/absence of the paper sheet, a transport mechanism configured to transport the paper sheet, driving means configured to drive the transport mechanism, and a controller unit configured to control the driving means, wherein the controller unit controls the driving means so that the paper sheet is transported by the transport mechanism based on a detection result of the paper sheet detection sensor.

What is claimed is: 
     
         1 . A paper sheet processing apparatus including a plurality of transport units connected in a transport direction to which a paper sheet is transported, each of the plurality of transport units comprising:
 a paper sheet detection sensor configured to detect presence/absence of the paper sheet;   a transport mechanism configured to transport the paper sheet;   driving means configured to drive the transport mechanism; and   a controller unit configured to control the driving means,   wherein the controller unit controls the driving means so that the paper sheet is transported by the transport mechanism based on a detection result of the paper sheet detection sensor.   
     
     
         2 . The paper sheet processing apparatus according to  claim 1 , wherein
 the plurality of transport units includes a first transport unit and a second transport unit that are arranged adjacent to each other,   the paper sheet detection sensor of the first transport unit and the paper sheet detection sensor of the second transport unit include an emission unit configured to emit detection light toward a transport path of the paper sheet and a reception unit configured to receive the detection light, and   the reception unit of the second transport unit receives the detection light emitted by the emission unit of the first transport unit.   
     
     
         3 . The paper sheet processing apparatus according to  claim 2 , wherein
 the first transport unit has a first reflection member configured to reflect a portion of the detection light emitted by the emission unit of the first transport unit toward the second transport unit, and   the second transport unit has a second reflection member configured to reflect reflected light reflected by the first reflection member toward the reception unit of the second transport unit.   
     
     
         4 . The paper sheet processing apparatus according to  claim 1 , wherein
 the transport mechanism has a plurality of transporting members that are rollers or belts to transport the paper sheet while contacting with the paper sheet at different positions in a width direction orthogonal to the transport direction,   the transport unit includes a plurality of paper sheet detecting sensors for detecting the presence or absence of the paper sheet at the different positions in the width direction, and a plurality of driving means for driving the plurality of transport members, and   the controller unit controls the plurality of driving means to correct skewness of the paper sheet based on a detection result of the plurality of paper sheet detection sensors.   
     
     
         5 . The paper sheet processing apparatus according to  claim 1 , wherein
 the plurality of transport units includes a third transport unit and a fourth transport unit that are arranged adjacent to each other,   the transport mechanism of the third transport unit and the fourth transport unit has a transporting member that is a roller or a belt to transport the paper sheet while contacting with the paper sheet, and   a position with respect to the transport direction of a fourth-transport-unit-side end of the transporting member of the third transport unit is aligned with a third-transport-unit-side end of the transporting member of the fourth transport unit or is closer to the fourth transport unit side than the end.
