PURPOSE:To shorten a copying time by allowing a feeding means to operate during the preliminary rotation of a rotating body and to feed an original. CONSTITUTION:When the original reaches the original detector of a feeder part, collectors of phototransistors Q1 and Q2 go up to H, so inputs RESET to Q8 and Q9 are both at H and outputs -Q of Q1, Q2 both go up to H to turn on plungers ClA and ClB through Q13 and Q14, so that a feed roller is stopped and enters a stand-by state. At this time, the original is carried whil clamped between rollers which rotate all the time, so it is sent out to a feeder part. Further, when a signal ADF is inputted and ClA and ClB turn off, the input of an OR gates Q55 connected to outputs of drivers Q13 and Q14 goes up to H, so the input of a one-short multivibrator Q56 goes up to H. Its output, therefore, turns on a transistor Q57 to energize a relay K6, whose contact energizes a relay K5, the contact of which drives a motor M2 which drives the conveyor belt of a feeder part setter part for a specific time.
