ある。The above-described conventional certificate front / back identification device has a position error when the certificate medium is set in the automatic teller machine and a position when the certificate medium is conveyed in the automatic teller machine. There is a drawback in that the light amount of the reflected light varies depending on the deviation or the warp of the certificate medium itself, and thus the front and back of the certificate medium are erroneously identified.

At the position corresponding to the black line 2 of the certificate medium 1, the light receiving element 3 is provided on the front surface side of the certificate medium 1 and the filament light bulb 4 is provided on the rear surface side. When the filament bulb 4 is turned on, the light emitted from the filament bulb 4 passes through the certificate medium 1 and is received by the light receiving element 3.
The intensity of light received by the light receiving element 3 is different between the place where the black line 2 is provided and the place where the black line 2 is not provided in the certificate medium 1. The output signal from the light receiving element 3 is input to one terminal of the comparison amplifier 6, and the other terminal of the comparison amplifier 6 is connected to the reference voltage input terminal 5 to which the voltage dividing resistors 10a and 10b are connected. The reference voltage is input via.
The output signal of the comparison amplifier 6 is input to one terminal of the comparison amplifier 8, and the reference time is input to the other terminal of the comparison amplifier 8 via the reference time input terminal 7.

の表裏を識別することができる。When the certificate medium 1 is conveyed in the correct state, the output signal of the light receiving element 3 is input to the comparison amplifier 6, so that the output signal of the comparison amplifier is input to the comparison amplifier. 8 and the output signal of the comparison amplifier 8 is output to the output terminal 9. However, when the certificate medium 1 is conveyed with the front side and the back side thereof being reversed, the output signal of the light receiving element 3 is output. No output signal is generated at the output terminal 9 because it is not input to the output terminal 9. Therefore, the front and back of the certificate medium can be identified without being affected by the positional error when the certificate medium is set, the positional deviation when the certificate medium is conveyed, and the habit of the certificate medium itself.
