幣の真贋を判定するのが一般的であった。FIG. 5 shows a device such as a vending machine.
As shown in (a), the bill 1 is conveyed by the conveyer 2 such as a belt, and the reflected light sensor 3 provided at a predetermined position of the conveyer 2 causes the bill 1 to determine the data regarding the printing pattern of the bill 1. It is common to determine the authenticity of a banknote by reading it every time the transport length of the banknote is moved and comparing it with the data about the printing pattern of the genuine banknote stored in the memory in advance.

た。Here, the reflected light sensor 3 comprises a light emitting portion 4 and a light receiving portion 5, and the light emitting portion 4 emits visible light of a constant light amount using an LED or the like as a light source and is emitted from the light emitting portion 4. The light beam is applied to the bill 1 and reflected on the surface of the bill 1. Since the amount of the reflected light changes depending on the color or shade of the print pattern, the light receiving unit 5 detects the pattern by receiving the reflected light and converting it into an electric signal corresponding to the amount of light. However, it is difficult to detect a paper sheet, which is a copy of a banknote by a color copying machine, as a fake article, and prohibit the acceptance thereof, using only the conventional apparatus as described above.

装置を用いるのが一般的であった。Therefore, for example, as shown in FIG. 5B, in order to read the watermark pattern of the banknote 1 together with the print pattern, a light receiving section 5 ', instead of the reflected light sensor, is provided on the upper surface of the conveying path through which the banknote 1 passes. A device which is equipped with a transmitted light sensor 6 which is a transmitted light type optical sensor in which a light emitting portion 4'is arranged on the lower surface and which is compared with the data regarding the printing pattern and the watermark pattern of the genuine bill stored in the memory in advance is described. It was common to use.

と云う問題点もあった。However, since a fake bill that is forged by copying a bill with a copier using transmitted light contains a watermark pattern, it is difficult to eliminate it as a fake bill by the above-mentioned authenticity discriminating apparatus. There was a defect that said. There is also a problem in that even if the bill is a genuine bill, the reception is prohibited due to noise caused by a fold line on the bill or dirt.

Based on the data from the position detecting means 7 that operates in association with the conveying means 2, data regarding the watermark pattern of the banknote 1 by the reflected light sensor 3 and the transmitted light sensor 6 provided at the predetermined positions of It is read every time it moves by the transport length of. At this time, both sensors are arranged on a straight line parallel to the banknote transport direction in order to read the print pattern of the banknote 1 at the same position. Thus, the data output from both sensors are compared by the CPU 8.

ない。For example, as shown in FIG. 3A, in the case of a bill in which the patterns A and B and the watermark 10 are printed on the surface of the paper piece 9, if the bill inserted in the apparatus is a genuine bill, the same figure ( As shown in b), the reflected light sensor recognizes only the printed pattern on the surface thereof, and therefore the level 11 corresponding to the patterns A and B
And 12 and the sensor output exhibiting the level 13 for the paper piece 9 are obtained, while the transmitted light sensor shows the same figure (c).
As described above, since the pattern of the watermark 10 is output as data together with the print pattern, when the CPU 8 compares the output data of the portions of the watermark 10 from both sensors, they do not match.

の受付を禁止する。On the other hand, in the case of a fake bill copied by using the transmitted light type copying machine, the output data of the portions corresponding to the watermark 10 from both the sensors are the same as shown in FIGS. Similarly, in the case of fake banknotes copied by using the reflection light type copying machine, the output data of the portions corresponding to the watermark 10 from both sensors match as shown in FIGS. If they match, the product is identified as a fake product and the acceptance is prohibited.

Alternatively, noise generated due to dirt or the like is canceled by the data comrades, and can be limited.

小限に抑えることが可能となる。Therefore, as described above, according to the present invention, the discrimination ability of the authenticity discriminating apparatus is improved by using only two optical sensors having a relatively simple structure, and the output data from the two optical sensors are compared. Since it is only necessary to store the basic data in advance, it is possible to minimize the memory capacity.

あろう。Although the present invention has been described above by taking as an example the one configured to identify the authenticity of banknotes, the present invention is not limited to this, and watermarks of securities other than banknotes, etc. It is obvious that it may be applied to a device for discriminating the pattern. Further, as shown in FIG. 4, the two optical sensors constituting the authenticity discriminating device are composed of a common light emitting part 4, a light receiving part 5 for receiving reflected light, and a light receiving part 5'for receiving transmitted light. It will be clear that equivalent results are obtained.
