Abstract

PURPOSE: To secure the selection of the light sources for the slip in accordance with the colors of information requiring no reading of the items written onto the slip by preparing plural number of light sources to secure the beams of different head wavelengths and then providing the special light source selection means.
CONSTITUTION: The diagram shows both the wavelengths and relative intensity of the beams emitted from plural number of light sources plus the reflection factors of the sheet, the ball pen, the pencil and the like respectively. The light source part comprises color fluorescent lamps 1-1W1-3, reflector plates 2-1W2-3, light shielding plates 3-1W3-2, slip 4, condenser lens 5 and photoelectric conversion element 6 each. Then a pair of light shielding plates 3-1 and 3-2 are located above slip 4 with the appropriate space secured along with installation of lamps 1-1W1-3. In the state shown in the diagram, only lamps 1-1 and 1-2 irradiate slip 4 owing to presence of the light shielding plates. Thus the information requiring no reading is written in green onto slip 4, and the information requiring reading is written via the ball pen or the like. As a result, only the necessary information can be read out.
