Paper sheet handling apparatus and correction method of paper sheet handling apparatus

Abstract

A apparatus includes an image sensor unit which includes an image capturing element that captures a banknote so as to discriminate the banknote, a controller that controls the image sensor unit, and a first attachment part, to which the image sensor unit is attached to be detachable, and which includes a connection terminal that connects the image sensor unit and the controller with each other, and which is arranged in a conveyance path for conveying the banknote.

What is claimed is: 
     
         1 . A paper sheet handling apparatus comprising:
 an image sensor unit which includes an image capturing element that captures a paper sheet so as to discriminate the paper sheet;   a controller that controls the image sensor unit; and   a first attachment part that includes:
 a connection terminal that connects the image sensor unit and the controller with each other, 
 the first attachment part, to which the image sensor unit is attached to be detachable, being arranged in a conveyance path for conveying the paper sheet. 
   
     
     
         2 . The paper sheet handling apparatus according to  claim 1 , wherein
 the image sensor unit includes:
 a plurality of image capturing elements; 
 a storage element that stores correction information for correcting outputs of the plurality of image capturing elements; and 
 a circuit board on which the plurality of image capturing elements and the storage element are arranged. 
   
     
     
         3 . The paper sheet handling apparatus according to  claim 1 , further comprising:
 a sensor unit that includes:
 at least one of an ultraviolet sensor unit that discriminates a fluorescent component of the paper sheet and a magnetic sensor unit that discriminates a magnetic component of the paper sheet; and 
   at least one second attachment part that includes:
 one or more connection terminals that connect the at least one sensor unit and the controller with each other, 
 the at least one second attachment part, to which the at least one sensor unit is attached to be detachable, being arranged in the conveyance path. 
   
     
     
         4 . The paper sheet handling apparatus according to  claim 3 , wherein
 the ultraviolet sensor unit includes:
 an ultraviolet sensor that discriminates the fluorescent component of the paper sheet; 
 a storage element that stores correction information for correcting an output of the ultraviolet sensor; and 
 a circuit board on which the ultraviolet sensor and the storage element are arranged, and 
   the magnetic sensor unit includes:
 a magnetic sensor that discriminates the magnetic component of the paper sheet; 
 a storage element that stores correction information for correcting an output of the magnetic sensor; and 
 a circuit board on which the magnetic sensor and the storage element are arranged. 
   
     
     
         5 . The paper sheet handling apparatus according to  claim 3 , wherein
 to the at least one second attachment part, one or more dummy members are attached to be detachable instead of the at least one sensor unit.   
     
     
         6 . The paper sheet handling apparatus according to  claim 1 , further comprising:
 a plurality of conveyance-path constituting bodies that is configured to be dividable from a division surface which is arranged along a conveyance direction of the paper sheet, wherein   the first attachment part is arranged so as to have an opening part on the division surface of the conveyance-path constituting bodies.   
     
     
         7 . A correction method of a paper sheet handling apparatus, the method comprising:
 correcting an output of an image sensor unit based on correction information stored in a storage element of the image sensor unit that captures and discriminates a paper sheet.   
     
     
         8 . The correction method according to  claim 7 , further comprising:
 correcting, based on correction information stored in storage element of at least one of an ultraviolet sensor unit that discriminates a fluorescent component of the paper sheet and a magnetic sensor unit that discriminates a magnetic component of the paper sheet, an output of the one sensor unit.
