Abstract
An image reading device for reading an image of an object includes a multi-color light source which projects light rays with at least three colors onto the object, at least three monochrome image sensor rows, and at least a lens row provided between the object and the monochrome image sensor rows, wherein reflected light rays are imaged directly onto the monochrome image sensor rows through the lens row, and wherein switching between any two colors occurs only once every time the multi-color light source, the image sensor rows, and the lens row are moved for a predetermined distance. The image reading device is able to read color and monochrome images.
