Abstract

PURPOSE:To eliminate the need to correct upside-down copies in direction even after book originals are copied according to the pages by dividing an optical movement system and an original setting table into the 1st and 2nd copying and moving processes corresponding to the length of an original, and by scanning and exposing the 1st exposure area of the original in the 1st process and the 2nd exposure area in the 2nd process. CONSTITUTION:The 1st and 2nd copying processes are provided to copy the 1st surface A1 and 2nd surface A2 of an original A. In the 1st copying process and 2nd copying process, the moving member of an optical system moves from an initial position a1 to the position a2 of the 3rd detecting means X3 through the position a2 of the 2nd detecting means X2 over exposure; in the 1st copying process, it scans on the 1st surface A1(l1) between positions a1 and a2 and in the 2nd copying process, it returns from the position a3 to a2 and moves from the position a2 to the a3 to scan on the 2nd surface A2(l2) over exposure, thus taking a copy.
