Abstract
PURPOSE:To read an original while preventing the deterioration of picture quality by synchronizing the conveyance of the original with the scan of a linear solid-state image pickup element, and turning on a light source for original illumination to generate high output only a short period for every scanning line. CONSTITUTION:An original 1 is conveyed by rollers 2 and irradiated with fluorescent light 3, and a facsimile image on the original 1 is formed on a linear solid-state image pickup element 5 through a lens 4 and then converted photoelectrically. In this case, Fig. A shows the scanning of the element 5, Fig. B shows the movement state of the original, and Fig. C shows the lighting period of the fluorescent light 3. Pieces of information on scanning lines N1, N2... on the surface of the original 1 are stored during the scanning periods n1, n2... of the element 5, and the fluorescent lamp 3 performs flash lighting only in the short ending period of each scanning line. During this period, the original 1 is still, so the picture quality never deteriorates.
