Claims

[Scope of Claim for Utility Model Registration] (1) A one-dimensional photoelectric conversion element that is placed facing the surface of a document on which a color image is written and that scans and reads the color image by itself, and a gap between the surface of the document and the one-dimensional photoelectric conversion device. A disk-shaped color filter is installed in the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter, and is connected to the color filter. A driving motor that rotates the color filter in synchronization so that the photoelectric conversion element scans the color filter by the number of color separation patterns, and a drive motor that is interposed between the color filter and the one-dimensional photoelectric conversion element, and is irradiated with a light source to generate color. A color image input device comprising: a condenser lens that focuses light transmitted through a filter onto a one-dimensional photoelectric conversion element. (2) A one-dimensional memory that stores basic characteristic data of the color separation pattern of the color filter, which is output by reading a plain document surface consisting of a reference color with a one-dimensional photoelectric conversion element through a color filter, and a color image. The position of the color filter is controlled by a position detection element, which reads the written document surface with a one-dimensional photoelectric conversion element through an output filter and outputs the color image data and basic characteristic data read from the one-dimensional memory. 2. The color image input device according to claim 1, further comprising a processing circuit that outputs a desired color image reading signal by comparing the data in correspondence with each color separation pattern.
