Abstract

PURPOSE:To attain both high speed copying and high picture quality at the same time, by connecting two forward and reversing motors for driving an optical running body with a driving belt, and connecting the optical running body to an intermediate part of its driving belt. CONSTITUTION:When a copy switch 51 is turned on, the first and second FF52, 53 are set, and the start time T1 is made by a motor controlling circuit 54. When a lens mount is started and passes through a start position sensor 55, the second FF53 is reset, and an exposure time T2 is made. Subsequently, when the lens mount passes through an end position sensor 56, the first FF52 is reset, the third FF57 is set, a return start time T3 is made, and both motors become a reversing state. When the lens mount moves in reverse and passes through a start position sensor 55, the fourth FF58 is set, a damping time T4 is made, and furthermore, when it passes through a home position sensor 59, a holding time T5 is made, and 1 cycle is finished. In this case, unless a repeat counter 60 is ''0'', said operation is repeated.
