#FIG. 1 is a sectional view showing a structure of an image formation apparatus according to the present invention.

#As shown in FIG. 1, an image formation apparatus 100 mounts thereon an automatic original feed unit 101. The unit 101 feeds leftward an original set upward on an original tray 130 from its initial page one by one in due order by a pickup roller 131, carries the fed original from left to right above a previously set running read position on a platen glass 102 through a curved path, and then carries the original outward. At a time when the original carried from left to right passes through the running read position on the glass 102, an image on this original is read by a scanner unit 104 supported at a position corresponding to the running read position. Concretely, when the original passes through the running read position, a face of the original to be read (referred as read face hereinafter) is illuminated by light from a lamp 103 of the scanner unit 104, and reflected light from the read face of the original is guided to a lens 108 through mirrors 105, 106 and 107. The light passed through the lens 108 is color separated by an RGB color separation filter and then visualized as an image on an image pickup face of an image sensor unit 109.
