Abstract
A color image reader for decomposing two-color images into independent color components includes a color-separating mirror which is provided with a multi-layer interference filter on one of opposite major surfaces thereof. The other surface of the mirror serves as a reflection surface. Image light incident to the mirror is separated into two different color components which are then redirected to propagate in the same direction. The two color components respectively are focused to different line image sensors.
