PURPOSE:To feed paper steadily by providing a roll paper pushing member and a shaft pushing member connected thereto for preventing the excessive feeding of the paper when the paper feeding 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. 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 such inertia energy is absorbed by the frictional resistance between a shaft pushing member 23 and a roll 25, and the shaft 5 is stopped without fail almost at the same time with the roll 3. When the diameter of the paper 1 is small, the inertia force is small, and there is a fear to feed the paper excessively due to the over-revolution of the shaft 5. But, a roll paper pushing member 21 is rotated round a bar member 22 to be risen, and accordingly, the shaft pushing member 23 is risen to push the roll 25 stronger. |
