Abstract

PURPOSE:To easily set an optical path distance, by providing a cam mechanism moving a pulley of an adjuster, in an optical path adjuster for an electronic copy machine possible for variable magnification. CONSTITUTION:In a linking mechanism for a drive source and sanning section changing the rotating movement into reciprocating movement for the scanning of an electronic copy machine, A pulley 40 is provided by detouring an endless belt 35a of a drive device moving a mirror 45 to adjust the optical path 76 and the pulley 40 is moved by taking the shaft 55 as a center through the rotation of a cam, allowing to move the mirror 45 through the adjustment of a position of the belt 35a. The optical path 76 between lens originals can easily be adjusted through the selection of the cam according to the rate of contraction.
