Abstract

PURPOSE:To avoid adverse effect on a copied picture, by taking the number of vibrations generated at every pitch in case of a chain etc. to a high speed being a high number of vibrations which does not deteriorate an image MTF. CONSTITUTION:The number of teeth of a sprocket 13 fitted to a main motor 2 is three times of conventional systems. Since the speed of a chain 4, timing belts 8 and 11 is taken three times the conventional speeds, the number of revolutions of an original carrying belt driving shaft 1 is reduced to 1/3 by a gear. That is, the timing belt 11 drives a gear 15 (18 teeth) geared with a gear 14 (54 teeth) fitted to the said driving shaft 1 and a pulley 16 (19 teeth) fixed coaxially. Thus, the speed of the chain 4 and the timing belts 8 and 11 is taken three times the conventional speeds and the number of vibrations due to the chain and the timing belts can be increased.
