Paper identification device and paper processing device

Abstract

It relates to a paper identification device and a paper processing device. The paper identification device includes: first and second conveying mechanisms arranged at a predetermined distance in the paper conveying direction to convey paper; an information detection unit is installed on the first and second conveying mechanisms so as not to block the detection range Between, detect information from paper class; The surface forms a first entry angle θ1, and when the second entry direction of the paper entering the second conveyance mechanism from between the first and second conveyance mechanisms forms a second entry angle θ2 with the conveyance reference plane, the first entry angle θ1 and the second The two-entry angle θ2 is set to be equal to or less than a predetermined value determined by the positions of the first and second conveying mechanisms and the information detecting unit, and the allowable deviation distance of the sheets from the conveying reference plane of the position of the information detecting unit.

Description

[0001] This application is based on Japanese application Nos. 2013-170795 (filing date: August 20, 2013) and No. 2013-170796 (filing date: August 20, 2013), and enjoys the priority of these applications. This application incorporates by reference these applications in their entirety. technical field [0002] Embodiments of the present invention relate to a paper sheet identification device and a paper sheet processing device. Background technique [0003] Conventionally, in order to convey a sheet while recognizing it, a technique of conveying the sheet in an unbound state and acquiring an optical image of the sheet by an optical sensor is known. [0004] However, when the unbound paper is guided by the fixed guide, the paper conveyance speed is slowed down due to frictional resistance between the paper and the fixed guide, and conveyance failure may occur. In addition, even when a translucent fixed guide is used for the optical sensor, the translucency may decrease due to ...

[0004] However, when the unbound paper is guided by the fixed guide, the conveying speed of the paper is slowed down due to the frictional resistance between the paper and the fixed guide, and a conveying failure may occur.

In addition, even when a translucent fixed guide is used for the optical sensor, the translucency may decrease due to adhesion of dirt, dust, etc. Get an image of the paper class
