PURPOSE:To prevent color blurring and to execute reading and copying of different places simultaneously by setting up copying elements at the same pitch as that of an optical system of each color which reads out an original. CONSTITUTION:Normal lenses 3a-3c with fixed magnification are optically adjusted except the adjustment of magnification size, which is executed at the writing of B, G and R signals in buffer memories 7a-7c. The fitting pitch P of R, G and B three CCD line sensors 5a-5c in the subscanning direction is set up to the same pitch of the heads 10h of ink jet devices 10a-10c. Said constitution makes it possible to absorb the shift of picture drawing time, prevent color burring and execute the reading and copying different places simultaneously.
