Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Fig. 1 shows a schematic diagram of a paper processing device 1 (hereinafter simply referred to as processing device 1) according to an embodiment of the present invention.

[0031] The processing device 1 has a throw-in unit 2, a fetching unit 4, an orientation correction unit 5, an inspection unit 10 (paper identification device), a reject and collection unit 6, an orientation changing unit 7, a plurality of Sorting and collecting units 8a to 8f and control CPU9. A plurality of sheets P to be inspected are inserted into the insertion unit 2 . The take-out unit 4 takes the inserted sheets P onto a carrier path 3 one by one. The orientation correcting unit 5 corrects the transport orientation of the paper P taken onto the transport path 3 . The inspection unit 10 inspects the paper P that has passed the orientation correction unit 5 . The reje...

Abstract

A paper sheet processing apparatus has an inspection unit which optically detects paper sheets. The inspection unit has a plurality of image sensing units (21 to 23) and a signal processing unit (30). A sensing CPU (20) of the signal processing unit (30) detects image data of paper sheets via the image sensing units (21 to 23), reads a correction coefficient stored in advance for each type of paper sheets in a memory (200), and discriminates the paper sheets on the basis of the image data detected by using the correction coefficient.

Description

technical field [0001] The present invention relates to paper discrimination (discrimination) apparatus for discriminating stain level or true / false by inspecting paper, paper processing apparatus having paper discrimination apparatus and paper discrimination method. Background technique [0002] Generally, a paper discriminating apparatus determines a standard regarding a paper soiling level as follows. That is, by feeding the medium used for adjustment or the paper itself prepared for adjustment into the device, the difference between authentication levels depending on the individual difference between devices is corrected, (for example, refer to Japanese Patent Application KOKAI Gazette No. .2003-99837). [0003] For example, when there are five kinds of sheets as objects of authentication, the following three methods can be considered as methods of correcting the authentication level. [0004] In the first method, the five kinds of sheets were fed in units of 1000 shee...
