Abstract: PURPOSE:To prevent latent images to be formed on respective photosensitive bodies at a prescribed timing from being shifted each other by setting up the mutual distances among picture exposing parts of plural exposing devices with the integer times of the peripheral length of a pulley. CONSTITUTION:The peripheral length of a driving pulley 28 which is a pulley for moving an original board 2 to expose a picture is set up so that the mutual distances l1, l2 among respective picture exposing parts La-Lc are integer times of the peripheral length of the pulley.

This phenomenon is applied to any point on the periphery of the pulley. The average speed between the integer periods such as one period and 2nd period is fixed from any point, so that the moving distance of the original board is essentially fixed in each period.
