摘要： The present invention is directed to a light source switching type color image scanner in which a color signal can be read out at high speed by reducing a read-out time. A red light source (3), a green light source (4) and a blue light source (5) which can be selectively switched are disposed under an original document holder (1) on which an original document (2) is held. Further, there are disposed a mirror (7) and a lens (8) which are used to focus a reflected image of the original document (2) onto a CCD linear image sensor (6). The CCD linear image sensor (6) includes a shutter gate (12) and a shutter drain (13) which are used to reset signal charges of remaining lights from the respective light sources (3), (4) and (5). The reset of a signal charge begins before a next color light source is energized.
