The present invention relates to a counterfeit money identification device used to identify counterfeit money and similar counterfeit documents.

In general, most securities, such as banknotes, are frequently made of special paper containing 90% or more cotton fiber to prevent long-term preservation and damage, and the surface is often treated with special chemicals. Alternatively, various securities have unique surface reflection and absorption characteristics.

Conventional counterfeit bill identification techniques include the following. In view of the fact that a conventional paper has a fluorescence property with one conventional technology, there is a technique of determining that a fluorescent light is detected by using an ultraviolet lamp and displaying a fluorescent light as a counterfeit. However, such a prior art has a problem that visual identification is possible, but electronic identification is very difficult because certain bills are surface-treated using fluorescent. Furthermore, recently, the rapidly spread recycled paper has a fluorescence-free property, so the counterfeit bill using these papers has a limit in authenticity determination.

As another method of the related art, there is a method for distinguishing between pneumoconiosis and pneumothorax by precisely analyzing an image printed on a bill. However, since this method requires a high degree of mechanical stability and sufficient time, it is limited to be applied to a high-speed banknote counter, cash deposit and withdrawal machine. Moreover, due to the recent development of precision printing technology, there is a problem that counterfeiting is not easy and the identification is not easy by the above method.

As another method of the related art, as the applicant has previously filed in Japanese Patent No. 1999-20335, there is a method of distinguishing ambush and atrophy by this value by detecting the intensity of transmitted and reflected light and extracting the intensity of absorbed light. However, this also has a problem that the volume of the device is large, and the visual identification is not easy.

In addition, such a conventional method has a possibility that an error may occur in the process of determining whether pneumoconiosis and falsification based on the information obtained by collecting the information while passing the bill to be examined into the device. That is, in the conventional art, when the bill is stopped and moved during the movement, the information of the stopped portion is collected repeatedly, thus acting as a factor of an error in the process of combining the collected information to determine the reading efficiency. There was a problem of this deterioration.

The present invention is to solve the problems of the prior art as described above, it is possible to visually determine whether the pneumoconiosis and forgery, and also to collect information only during the movement of the bill, thereby improving the reading efficiency of the bill Its purpose is to provide counterfeit money identification devices.

In addition, the present invention has another object to provide a counterfeit bill identification device that is easy to carry and use.

In order to achieve the above object, the present invention, the main body is formed in the longitudinal direction banknote passing groove in a predetermined depth; A visual recognition unit installed at an upper side of the banknote passing groove of the main body to visually recognize letters or figures displayed on the banknote passing through the banknote passing groove; Installed on and under the banknote passing groove of the main body adjacent to the naked eye recognition portion, and irradiates ultraviolet rays having a wavelength of a specific band to the banknote passing through the banknote passing groove, the ultraviolet rays reflected and / or transmitted from the banknote Electronic sensing unit for detecting whether the pneumoconiosis and pneumoconiosis; A banknote movement detecting unit installed at an upper side of the banknote passing groove of the main body and detecting a movement of the banknote passing through the banknote passing groove; A magnetic detector installed at an upper portion of the bill passing groove of the main body and detecting a magnetic ink component of the bill passing through the bill passing groove; At least one switch for determining an operating mode; And supplying power to the visual recognition unit, the electronic recognition unit, and the magnetic detection unit according to the operation mode selected by the switch, and from the electronic recognition unit only when a banknote movement detection signal is input by the banknote movement detection unit.
