PURPOSE:To prevent a paper from changing of its nature due to feeding by reversely rotating a shaft to feed a roll paper successively by the rotation of a conveying means when the conveying means is stopped. CONSTITUTION:When a feed roll 3 is operated by an external signal, a shaft 5 is rotated with a board member 11 pressing a bearing 6, and a roll paper 1 is successively unrolled and fed passing between rolls 3 and 4. At this stage, since a wheel 22 is rotated in the same direction with a rotor 20, the shaft 5 is free from being interfered. When a conveying means, the roll 3, is stopped, the shaft 5 is further rotated by inertia force to send out the paper 1. But, a motor 23 is driven at the same time with or a little later than a signal of paper stoppage to be rotated for a fixed time, and rotates the shaft 5 reversely via the wheel 22 and the roll 20. Thereby, the roll paper 1 is reversely rotated to absorb the loosening of the paper. |
