Description

Note counting device

The present invention relates to a bill counting device, and more particularly, to a bill counting device that can detect whether the bill of paper bills and counterfeit together with the count of bills.

The general bill counter had only a function for counting bills. The bill counting device and its control method of Patent No. 10-0271274, filed on August 12, 2000, provide a new bill counting device and a control method capable of detecting bills of different kinds of papers.

However, with the development of counterfeit technology, the counterfeit is manufactured closer to pneumonia, and it becomes difficult to accurately detect the counterfeit from pneumonia with a conventional banknote counter. The prior art detects gastric emptying and puffiness only by detecting whether or not UV light is printed on the lungs when detecting gastric emptying.

However, after that, counterfeit began to print UV as well. Therefore, it is impossible to detect pneumoconiosis and pneumothorax with only UV printing. However, in the case of counterfeit, the position or distribution of UV printing (distribution of ink) is different from that of pneumonia. Conventional bill counters that do not take into account these differences, that is, the method of distinguishing between pneumoconiosis and judging pneumonia by judging UV printing only in one place has a problem in that it is not properly distinguished.

Accordingly, an object of the present invention is to provide a banknote counting device that can detect the winding and falsification of banknotes even in the case of newly issued banknotes as proposed to solve the above-mentioned problems.

According to a feature of the present invention for achieving the object of the present invention as described above, the bill counting device for classifying and counting the bill type of the bill, and also detects whether the banknote is counterfeit transfer from the upper bill support to the lower bill support It is installed perpendicular to the conveying direction of the banknote is provided with the first and second color sensing means for detecting the reflected or transmitted signal from the banknote, such as luminance, color distribution and color pattern by the UV printing of the banknote different The UV printing characteristics of the position are respectively detected to detect whether the banknote is closed or counterfeit.

Looking at the counterfeit found in cash, even though the counterfeit is UV-printed like pneumoconiosis, the difference in print position or printing is different from pneumoconiosis. Therefore, in order to detect forgery from this difference, the present invention checks the printing state of UV printing in at least two places. To do this, color detection means are placed in two places perpendicular to the path through which the bill passes, and their detection results are compared to detect forgery. That is, since the UV printing density of banknotes is different from the left and right sides, the color sensing means on the left and right sides respectively detects reflection or transmission signal values such as luminance and color distribution by UV printing, and if they are different from each other, they are identified as pulmonary. Identify with. In case of no UV printing, the signal read from the left sensor and the signal from the right sensor are the same, so in any case (whether UV printing or not), the lungs are detected by the left and right sensors. Value is different and counterfeiting is the same value.
