Claims

[Scope of utility model registration request]

In a color document reading device that separates and reads a color document into a plurality of colors by placing a filter frame having a plurality of color filters in front of a sensor that reads image information and making the filter frame reciprocate, the filter frame is moved in a reciprocating manner. a holding member that holds the holding member in a neutral position; a fixing member that fixes the holding member;
A color original reading device comprising a positioning means for moving the fixing member along a movement locus of the filter frame and positioning the filter frame at a predetermined monochrome reading position.
