Problems solved by technology

[0005] However, even the same banknotes, from brand new banknotes that have just been issued, to dirty or damaged old banknotes used in the circulation process, have different optical and magnetic characteristics that serve as banknote identification factors. Large deviation, it is difficult to judge the authenticity with the above-mentioned previous methods

Embodiment Construction

[0023] Hereinafter, the details of the banknote identification device and the banknote identification method of the present invention will be described in detail with reference to the accompanying drawings.

[0024] Example.

[0025] figure 1 It is a block diagram showing the schematic structure of the banknote identification apparatus of this invention.

[0026] Such as figure 1 As shown, the banknote identification device has: a control unit 1 , a banknote insertion unit 2 , a banknote conveying unit 3 , a banknote acceptance unit 4 , a driving unit 5 , and an identification unit 6 .

[0027] The banknotes inserted from the banknote insertion unit 2 are transported by the banknote transport unit 3 driven by the drive unit 5 . And, the banknote conveyed by the banknote conveying unit 3 is judged by the recognition unit 6 to determine its denomination and authenticity, and the banknote judged to be a genuine banknote is controlled by the control unit 1 to control the drive ...

Abstract

A banknote identifying machine and method for testing a banknote for genuineness stably without being affected by a sensor or contamination on the banknote. Transmission photosensors (61) are moved over a banknote to be tested to scan the banknote with a light beam along reading lines (L) to obtain patterns of an amount of transmitted light through the banknote (FIGS. 3(b) and 3(c)). Patterns (1a, 1b) of an amount of transmitted light corresponding to watermark portions are evaluated with maximum values (11, 12) of patterns of an amount of transmitted light corresponding to ordinary design portions other than the watermarks to determine whether or not there is any watermark in the banknote and to authenticate it.

Description

technical field [0001] The invention relates to a banknote identification device and a banknote identification method, in particular to a banknote identification device and a banknote identification method capable of accurately judging authenticity independent of the state of the banknote. Background technique [0002] Generally, identification of the denomination or authenticity of banknotes is performed by magnetically and optically extracting features of banknotes inserted by a user using a magnetic sensor or an optical sensor. [0003] The extraction of the optical features of banknotes with optical sensors is to extract the patterns, sizes, directions, etc. To judge the currency and authenticity of the inserted banknotes. [0004] In particular, the identification of the authenticity of banknotes by using a transmission-type optical sensor is to arrange the light-emitting element and the light-receiving element at a fixed distance, transport the banknotes between them,...
