Abstract

PURPOSE:To enable the read-in of a picture with high magnification, by effectively using almost all the unit elements in a primary dimension solidstate image sensor when the picture with small-sized construction is read in, through varied magnification of a read-in optical system. CONSTITUTION:A read-in lens 6 moves with an image sensing box 5 to form the image of an original 1 with different magnification. A primary solidstate image sensor 8 is located on the focus of the read-in lens 6. A drum 2 is supported in rotational free and driven with a step motor 3 operated with pulses from a pulse generator PG to feed the original 1 toward subscanning direction with a given pitch pulsively. The said box 5 takes four places as H1, H2, H3 and H4 on an optical bench 4.
