用いられる。Referring to FIG. 1, the nibrate 7 is spaced vertically
A banknote (not shown) is inserted between the lower plate 8 and the lower plate 8 in the direction of arrow 12, and the banknote is fed li! (not shown). It passes through this space by ts. The optical system is arranged perpendicular to the running direction of the banknote. A window 11 is bored along the optical system in the upper and lower play 1 to 7.8. Lower plate 8
A red LED array light source 3 for transmitted light is arranged below, and a transmitted light diffusing plate 4 is provided at a window position 8 on the lower plate 1. A pair of green LED array light sources 1.2 for reflected light are arranged on both sides of the window 11 on the upper play 1-7 so as to be able to project light onto the banknotes through the window.
Furthermore, above the upper plate 7, specifically above the window 11, there is a SELFOC lens array 5 and -
A dimensional image sensor 6 is arranged. This -dimensional image sensor 6 converts the red transparent real image and the green foul real image into electrical signals. The output electrical signal 101 of the -dimensional image sensor 6 is input to the analog multiplexer 9 . The red transmitted light from the light source 3 is responsible for recognizing the shape of banknotes.
The green reflected light from the light source 1.2 is used to recognize the shading pattern of the banknote.

信号１０３を得る。In the above configuration, the light source 3 transmits the bill through the window 11 when the bill travels between the uniplates 7 and 8.
The red transmitted light and the green reflected light from the light source 1.2 that is reflected on the surface of the banknote through the window 11 are transmitted to a one-dimensional image sensor 6 by a SELFOC lens array 5 to form an erect, equal-magnification real image.
Connect to the photoelectric conversion surface. The -dimensional image sensor 6 performs photoelectric conversion to generate a composite electric signal 101 of a red transmitted signal and a green reflected signal. Now, the green LED array lighting current 201 is cut off by the light source lighting circuit 10, and the red LED for transmitted light is turned off.
A D-array lighting current 202 is supplied to the light source 3, and an analog multiplexer 9 connects the composite electric signal 101 to the red transmission electric signal 102 side to obtain the red transmission signal 102. Next, the red LED array lighting current 202 for transmitted light is cut off, the green LED array lighting current 201 for reflected light is supplied to the light source 1.2, and the synthesized electric signal 10 is sent to the analog multiplexer 9.
1 to the green reflected electric signal 103 side to obtain the green reflected electric signal 103.
