PURPOSE:To prevent fluctuation of the speed even for the generation of expansion and contraction of a driving belt, by driving a carrying belt, a driving press roller, and a pulse generating rotary plate by one driving belt. CONSTITUTION:Carrying belts 3 and 4 are stretched along the carrying path of a magnetic card, and a magnetic head 30 and a driving press roller 31 which is energized to the head 30 side and is driven are provided oppositely to each other with the carrying path interposed. Driving shafts of belts 3 and 4 and the roller shaft of the roller 31 are extended to one side of the carrying path, and input pulleys 29 and 43 are mounted in the extended end part. Further, an input pulley 50 of a pulse generating rotary plate 45 is provided in the position near the input pulley of the roller 31. One driving belt is stretched on the output pulley from a motor 51 and respective input pulleys. Thus, fluctuation of the speed is prevented even if the driving belt expands or contracts. |
