An image detector for bank notes is provided which can be made at low cost and in small size. The image detector comprises a pair of detector unitsincludes a first image detection sensorwhich detects an image of a first detection area mounted on one side of a detector unit, a first light emitting devicewhich irradiates light towards the first detection area, and a second light emitting devicewhich irradiates light towards a second detection area mounted on one side of the unit main bodybut in a different location from the first detection area, a pair of detector units is disposed so as to oppose one another across a bank note transportation path, in a manner which enables the image detection sensorof one of the detection unitsto detect an image of the second detection area of the other of the detection units

Image detector for bank notes

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).
