Abstract
PURPOSE: To achieve the compactification of slit exposure system by moving the supports of small mirrors at an equal speed in the specified linear directions and moving the small mirrors at non-equal speeds on the specified quadratic curves along with these.
CONSTITUTION: In the copying machine of slit exposure system, small mirrors 4, 6 are provided between a projecting lens 3 and photoreceptor 14 and the supports which support these mirrors 4, 6 respectively move in the A3, A4 directions respectively when a motor 10 runs, whereby the scanning on an original plane 1 is accomplished. Along with these movements, the respective small mirrors 4, 6 move at non-equal speeds on the specified quadratic curves by being quided by the grooves engraved in cam plates 5, 7 respectively, whereby the scanning on the original plane is accomplished in the A5 direction.
