Abstract
PURPOSE:To obtain a low cost and compact device by selecting the LED light source of a wavelength area the most suitable for the color of information applied on a medium and obtaining a reading resolution required according to the selected LED light source. CONSTITUTION:A light source selecting and driving circuit 4 selects and drives the light source for outputting the light of the most suitable wavelength area according to the color of the information to be read from the plural light sources 31, 32. A control circuit 7 switches the carrying speed of the medium 1 according to the selected light source and controls to lower the carrying speed of the medium so as to have the resolution required for reading when the output value of the light source is not a proper value such as a small value. A reflected light from the medium 1 is received by an image sensor 5.
