PURPOSE:To reduce the mental burden in the operator against a writing tool, by attaining partial reading of a original surely even if marking is blurred or stained, in a device reading picture with an image sensor. CONSTITUTION:A reading unit 12 is provided with a fluorescent lamp 121 irradiating a platen glass 13 from the under surface. The original is fixed with the platen glass 13 and a platen cover 14, and when the lamp 121 is illuminated, the reading position is irradiated. The irradiated light of the original is branched into two directions with a dichroic mirror 122, the wavelengths are selected and the image is formed on the 1st or the 2nd image sensor 125 or 126 via a lens 123 of 124. Two kinds of picture signals obtained at the 1st and the 2nd image sensors 125, 126 are applied to a color separation circuit in the reading unit 12 to form three kinds of picture signals such as black, red and cyan picture signals. |
