PURPOSE:To simplify a structure and to bring a roller into contact with a feed roller equally left and right, by fixedly providing a support part for energizing a roller shaft to the side of a feed rollr and supporting a taper part against the energizing force of the roller shaft. CONSTITUTION:A righthand end button 14 is pressed and a roller shaft 11 is slid to the left. By this operation, support parts 17, 18 support taper parts 15 and slide parallel parts 16 and, even if a hand is separated from the push button 14, a feed roller 7 is kept in a state spaced apart from a roller 10. Each taper part 15 is formed so that the outer diameter gradually becomes thick toward the right direction along the axial line. Subsequently, paper 19 is set and a lefthand end button 14 is pushed to displace the roller 10 to the side fo the feed roller 7. The roller shaft 11 is directly pushed up at both end parts thereof by springs 13. By this mechanism, the paper 19 can be contacted with the feed roller 17 under pressure equally left and right by the roller 10. |
