Problems solved by technology

[0017] In the past, in order to suppress the component cost of the banknote identification device, each sensor (magnetic, UV, etc.) was installed on the device one by one, but in the feature part When the position differs depending on the denomination of the banknotes, or when the position of the detection target deviates due to banknotes traveling obliquely during conveyance, etc., it will be difficult to accurately detect the characteristic parts of all banknotes

Embodiment Construction

[0036] Hereinafter, preferred embodiments of the present invention will be described. figure 1 It is a figure which shows the structure of the main part of the banknote identification device (paper type identification device) 11.

[0037] After the banknotes are put into the input unit 12, the banknotes are transported on a transport path (not shown). First, the image sensor 13 reads the image data of the banknotes. The judging unit 14 performs rotation processing or the like on the image data of the banknote detected by the image sensor 13, aligns the image data in a certain direction, and compares it with the image data stored in the reference data storage unit 15 as a reference for the banknote, and determines the banknote Currency, back and bottom of the table. The result of this determination is output to the discrimination unit 16.

[0038] In the reference data storage unit 15 are stored image data of the front, back, upper and lower banknotes of each currency type (data u...

Abstract

The present invention provides a paper type identifying apparatus and method for improving paper type identifying accuracy. A judging part (14) matches the image data of paper currency detected by an image sensor (13) with the pattern of data used as surface, back surface and upper and lower reference data of each currency and stored in a reference data storing part (15), and judges the currency type and state of paper currency. An identifying part (16) determines the optimal detection position of the feather portion of paper currency according to the judging result, such that a magnetic sensor (17) moves to the position for detecting the feather portion.

Description

Technical field [0001] The invention relates to a device and a method for identifying paper types such as banknotes and securities. Background technique [0002] A banknote identification device for authenticating banknotes is installed on an automated teller machine or the like of a bank. The banknote identification device has an image sensor that acquires image data of the banknote and a magnetic sensor that detects the magnetic pattern of the banknote. By comparing the magnetic data acquired by these sensors with pre-stored image data and magnetic data for authenticity determination, the identification of the banknote Authenticity. [0003] Patent Document 1 describes that the paper type recognition sensor can be moved in a direction orthogonal to the insertion direction of the paper type, and the sensor is moved along a zigzag track, thereby expanding the recognition range. [0004] Patent Document 2 describes that width position detection units that detect the positions of b...
