るためのものである。The operation will be described below. 2 in FIG. 4 and FIG.
As shown by the chain line, the bill 1 is the detection head 11 and the roller 3.
When conveyed between the roller 31 and the roller 1, the roller 31 rolls while the surface 1a of the banknote 1 is brought into contact with the detection surface 11a and slid. As a result, the front surface 1a of the banknote 1 is the detection surface 1
It is conveyed in the direction of the arrow while sliding on 1a. In addition, banknote 1
The belts are sandwiched between both side edges by a belt and conveyed. Therefore, the roller 31 is for lightly pressing the front surface 1a of the banknote 1 against the detection surface 11a of the detection head 11.

Incident on the inside. The light receiving element 32 receives the light emitted from the roller 31. The light transmitted through the bill 1 is the optical pattern drawn on the back surface 1b of the bill, or the front surface 1a.
Of the light receiving element 32 and the optical pattern of the back surface 1b.
Thus, these optical patterns can be detected.

There is little variation in the output of the light receiving element 32. Therefore, by the light receiving element 19 which receives the reflected light and the light receiving element 32 which receives the transmitted light, the optical pattern of the front surface 1a of the banknote 1, the optical pattern of the back surface 1b, or the optical pattern of the front surface 1a and the optical pattern of the back surface 1b is formed. The synthetic pattern can be read well. As a result, the detection accuracy is significantly improved.

光素子３２を保護することができる。Further, when two or more banknotes are overlapped, the amount of light transmitted through the banknote 1 is lower than that of one banknote, and the output of the light receiving element 32 is also reduced accordingly. Therefore, due to the decrease in the output of the light receiving element 32, the paper money is
It is possible to easily detect that more than one sheet has been loaded. As a result, the optical sensor 30 can be used in two ways, using reflected light and transmitted light, or only transmitted light, improving detection accuracy and expanding the types of detection (for example, selection of two layers stacked, thickness detection, etc.). Is planned. In addition, the light receiving element 32
