ことを特徴とするカラー原稿読取装置。 A plurality of color filters having different spectral characteristics are placed in front of the line sensor, and the image light obtained by optically scanning the document is passed through each of the color filters in turn and imaged on the line sensor, thereby detecting each color component. In a color document reading device for extracting image signals, a color separation filter is provided in which each of the above-mentioned color filters and a colorless filter for adjusting the amount of light incident on a line sensor are connected in a ring shape in a prismatic frame body. and a driving means for rotating the color separation filter in order to switch the position where the image light passes through each of the color filters and the colorless filter opposing thereto.
