Abstract

PURPOSE:To perform enlarged reading without using plural optical systems by installing a means to shift the subscanning direction by 1/2 line interval and a means to perform main scanning with the normal main scanning density of part K (1<=K<=2). CONSTITUTION:A picture read out by an optical system 302 is read out again as a picture element by a solid scanning element 303. After feeding a manuscript, the output of a distributor 304 is stored in the 1st buffer memory 305. When the main scanning has completed after reading, a signal to shift the subscanning direction by 1/2 line interval is inputted from a control device to a motor control circuit 307 and the distributor. At that time, the circuit 307 drives a main scanning motor 308 so that the manuscript is fed by the distance corresponding to 1/2 line. The distributor 304 is switched to the 2nd buffer memory 306 and a selection circuit 309 reads out the picture signal from the memory 306 and selects a picture element to be inserted according to the magnification to send the picture element to an insertion circuit 310. Since the circuit 310 has read out a picture signal from the memory 305 at that time, it synthesizes the read picture signal and the insertion picture element selected by the circuit 309.
