PURPOSE: To facilitate an effective control of copying in a clamped copying control system, in which the copy feed action, the return action to the start position of copying, and the pick feed action are performed one after another and the clamped feed is made at the preset clamp level.

CONSTITUTION: When a repeated copying is carried out while changing the clamp level between the position where the first clamp feed is made, for ex. Point A, and the position where clamp feed is stopped, for ex. Point B, by No.1 and No.2 memory means such as counters ACNT, BCNT for Point A and Point B, respectively, and a clamp level setting means for the setting counter 11, attainment of the copying to Point B shall be followed by quick return to Point A and by subsequent copy feed and clamp feed. If no clamp feed is made during said period, the setting shall be altered to the initial value of clamp level and the copying shall proceed to the next division.
