Abstract

PURPOSE:To vary scanning distance easily with small-sized constitution by synchronously rotating the 1st and 2nd pinions which drive a mangle rack, and by moving the 2nd pinion axially so that it freely engages with and disengages from the mangle rack. CONSTITUTION:A pinion 4 puts a mangle rack 1 in linear motion and semicircular motion, and an oscillatory member 17 coupled with the rack 1 through a guide plate 3 engaging with a through-hole 15 of a vertically movable oscillatory member 10, a link 16, etc., reciprocates by prescribed distance to perform scanning by the optical system, etc., of a copying machine. A pinion 29 similar to the pinion 4, on the other hand, is rotated, synchronizing with the pinion 4, by a timing belt 30, timing pulleys 6 and 25, etc., and also moved axially so that it freely engages with and disengages from the rack 1 through a guide part 34 moving through a pinion 36 and rack rod 33. Therefore, the rack 1 is driven by using the pinion 29 to vary scanning distance easily and securely with the small- sized constitution.
