PURPOSE:To use only one driving source to make the structure simple and small in size, by belting a transmission belt between paper feed driving rolls. CONSTITUTION:A roll 13 is fixed to a revolving shaft 12 provided in the exit of a stocker 10 and feeds out a paper 2 form the stocker 10. A belt driving pulley 14 is connected to the revolving shaft 12 through a one-way clutch 15, and the transmission belt is belted between the pulley 14 and a driving pulley 7 on the side of a paper feed driving roll 6. The paper 2 printed in a printing part 3 is fed intermittently for every printing by the roll 6 and is transported until the front end of the paper 2 is detected by a sensor 17. The pulley 7 is connected to a driving shaft 5 by a clutch 8, and the rotational force of the shaft 5 is transmitted to the revolving shaft 12 through the belt by the pulley 14 and the clutch 15, so that the roll 13 is rotated similarly to the roll 6. |
