PURPOSE:To eliminate a driving motor for a sheet feeder and provide a simple construction, by providing a mechanism for rotating a printer-side feeding motor in a forward direction to rotate a paper-supplying roller in a paper-supplying direction, and a mechanism for reversing a paper-feeding roller to bring the roller into contact with a slip paper or separate the roller from the slip paper. CONSTITUTION:When a gear1 is rotated in the direction of an arrow B-1, the paper 24 is fed in the direction of an arrow E by an amount of size (b). At this time, a cam 22 is rotated 45 deg. in the direction of an arrow B-3 to be set into the broken-line condition. An arm 13 is oscillated in the direction of an arrow D by energization by a spring means, and the paper-supplying roller 8 is pressed against the paper 24. When the gear 1 is rotated in the direction of an arrow A-1, the roller 8 is rotated in the direction of an arrow A-4, whereby the paper 24 is fed in the direction of an arrow F by the amount of size (b) to be returned to its initial position. At this time, the cam 22 is not rotated. When the gear 1 is again rotated in the direction of the arrow B-1, the cam 22 is rotated by 45 deg. in the direction of the arrow B-3, whereby the roller 8 is separated from the paper 24, resulting in a printing-starting condition on the printer side. |
