Abstract
PURPOSE: To obtain a miniature and lightweight device of low power consumption with the need for neither a lens system nor an optical system for color separation, by using one-way arrays of several light emission diodes different in luminous color as an illuminating light source for a color facsimile transmitter, etc.
CONSTITUTION: Once only array 18 of light emission diodes is caused to luminesce among arrays 18, 19 and 20, this light is scattered near line A of a color original and some of this scattered light strikes photoelectric converter array 21, where it is converted into an electric signal and read. Next, when only 19 is caused to luminesce with array 18 made to go off, this light is also scattered near line A of the color original and then made to strike array 21, where it is read after being converted into an electric signal. Then, only diode 20 is made to luminesce, so that the light will be read in the completely identical way after conversion into an electric signal. In this way, causing arrays 18, 19 and 20 to luminesce in sequence results in that three kinds of color information of the color original can be read by being converted into electric signals.
