- the second light emitting unit 81b is installed on both sides with the light receiving unit 81a in between so that light is irradiated from both sides at an incident angle of 45 degrees. This is because if there are scratches or folds on the banknote surface, and light is irradiated only from one side to the irregularities generated on these scratches or folds, the irregularities will inevitably become blocked by light. A spot may occur. For this reason, by irradiating light from both sides, it is possible to prevent shadows from being formed in the uneven portions, and to obtain image data with higher accuracy than irradiation from one side.
- the second light emitting unit 81b may be configured to be installed only on one side, and the configuration and arrangement of the light emitting unit 80 and the light receiving and emitting unit 81 described above are not limited to the present embodiment. It can be modified as appropriate.

- the authenticity of authenticity I try to raise more. That is, since red light and infrared light have different wavelengths, if transmitted light data or reflected light data from a plurality of lights having different wavelengths is used for determining the authenticity of a bill, it passes through a specific area between a genuine note and a counterfeit bill. Transmitted light and reflected light reflected from a specific region have properties that the transmittance and the reflectance are different. For this reason, in the above-mentioned light emission part (the 1st light emission part 80a and the 2nd light emission part 81b), it is trying to raise the identification accuracy of the authenticity of a banknote by using the light source of a some wavelength.
