Abstract
An object is to provide an image detector for bank notes which enables the cost to be lowered. Accordingly this has: a light emitting device(X) which is arranged facing an image detection sensor(X), and which irradiates light of a plurality of different wavelengths ranges towards a bank note on a bank note transportation path, and detects light of the light which has transmitted through the bank note with an image detection sensor(X); a light emitting device(X) which is provided on the same side as the image detection sensor(X), which irradiates light of a plurality of different wavelengths ranges towards a bank note S, and detects light of the light which is reflected from the bank note with the image detection sensor(X); an image detection sensor(Y) provided on the opposite side to the image detection sensor(X); and a third light emitting device(Y) provided on the same side as the second image detection sensor(Y), which irradiates light of a plurality of different wavelength ranges towards the bank note S, and detects light of the light which is reflected from the bank note S with the image detection image detection sensor(Y).
