PURPOSE:To attain a sharp recording picture visually, by obtaining three-color recording including black color with two image sensors, manufacturing the device inexpensively and recording a specified color and its complementary color. CONSTITUTION:A couple of fluorescent lights 1, 2 exposing an original 3 in slit shape toward the main scanning direction are fitted at the upper part of a scanner unit 32 placed freely reciprocatingly. After the reflected light of the original 3 by the lamps 1, 2 transmits a lens 4, the light reaches a dichroic mirror 33. The dichroic mirror 33 transmits the red color wavelength component among visual light and reflects the rest. The transmitted light (cyan) is formed on the 1st image sensor 6 and the photoelectric conversion is done in the unit of line. The reflected light is formed on the 2nd image sensor 7 and the photoelectric conversion is done in the unit of lines similarly. Serial picture signals 34, 35 outputted from the image sensors 6, 7 are impressed to a signal processing section 36, allowing to attain the desired three-color picture signal. |
