PURPOSE:To alleviate load at the time a paper is wround around a platen, by a system wherein a paper-supplying roller is rotated in two stages constituted of a primary rotation and a secondary rotation, and the total rotation quantity of the roller in the primary and secondary rotations per one sheet of paper is so set that the paper is transfered to a platen immediately before the paper comes off the paper-supplying roller. CONSTITUTION:The quantity of the primary rotation of a paper-supplying motor 37 controlled by a controlling circuit is so set as to cause an excess of feed of the paper 39 with the result of slight flexure of the leading end of the paper 39. The length l of a paper passage from the paper-supplying roller 33 to the platen 23 is set to be slightly smaller than the length of one sheet of paper 39. The total paper feed quantity achived by the primary and the secondary rotation of the motor 37 is set to be equal to or slighter larger than the length lof the paper passage. Accordingly, the paper 39 is transferred to the platen 23 immediately before it comes off the roller 33, comes off the roller 33 simultaneously with or immediately after completion of the secondary rotation of the roller 33, and is wound around the platen 23 while being fed by both feeding rollers 29 and the platen 23. |
