摘要： A variable magnification type copying system in which original can be duplicated with different magnification factors. Front and rear group lens systems are slidably mounted relative to one another upon front and rear frames which together make up a housing which is slidably mounted in the perpendicular direction upon a magnification unit frame. A stepping electric motor is mounted upon a plate which is rigidly coupled to the housing and slidably movable therewith. A pinion gear engaged with a pinion gear directly upon the output shaft of the motor is engaged with a rack of the rear frame. An L-shaped lever has a first end having a first cam follower held into abutment with a first cam rotatably mounted upon the output shaft of the motor and a second end connected to slidably move the front lens group by the front frame. A second cam is in abutment with a second cam follower upon the magnification unit to move the housing in the perpendicular direction.
