PURPOSE:To make the number of coying sheets of respective copying sizes optimum value, by determining the waiting times of optical devices in their home positions arbitrarily by each copying size. CONSTITUTION:A reference pulse generating part 22 generates timing pulses synchronously with a main motor 2. A control part 23 counts the timing pulses by utilizing a storage part 24, and controls load 26 via a driving part 25 according to the contents of said counter, thereby advancing a copying process. Detection signals whether optical devices 15, 17, 18 are in home positions or not are inputted to the part 23, by which transfer paper sizes are decided and the contents of the counter are corrected. Depending upon setting the correction value at what value, the waiting times of the optical devices in their home positions are changed. Hence, the number of copying sheets per unit time conforming to specified values is set by each transfer paper size. |
