Abstract: PURPOSE:To enhance the sensitivity to red color as well as to reduce a heat radiation from a bias light source to an optical sensor array by using a LED light source as the bias light source outside the LED light source for lighting and in the vicinity of the optical sensor array. CONSTITUTION:An LED light source array for lighting 2 emits in yellow-green color having a central wavelength of 570nm and disposed vertically of the paper surface, and the outgoing light OE is directed to the surface of the original copy on an optical axis O-O'. A reflected light OR makes an erect image of equal magnification on an optical sensor array 5 through a lens system 3. A bias light source 4 radiates an bias light OB to the sensor array 5 to enhance the response properties of the array. The bias light source 4 is a red-color LED of the GaAlAs system having a central wavelength of about 660nm, the brightness of which is more than 4 times that of the yellow-green LED. Therefore, the same brightness as the yellow-green LED can be obtained with a current as small as 1/4, and the heat dissipation becomes 1/16. CdSe1-xSx is used as the array 5, and (x) is selected as 0<=x<=0.3 for enhancing the red-color sensitivity. With this structure, the output correction of the optical sensor array becomes small, and the cooling in the container can be substantially reduced.
