<p>PURPOSE:To keep the stability of the travel of a recording paper and feed the sheet of recording paper at a uniform speed by providing a movable guide arm which is swingably set on the upper part of a guide plate. CONSTITUTION:A certain quantity of sag is ensured for a recording paper 10 prior to the operation of a cutter 11. When it becomes a cutter operating time, since the recording paper 10 is interposed between the edges of the cutter 11 and fixed, it is gradually stretched. As the recording paper 10 is stretched, a movable arm 16 is also rotated centering around a supporting pin 17 and pushed upward. At the moment when the cutter operating time is over, the sheet of recording paper is stretched to the maximum while the movable arm 16 also reaches its highest point. In this case, since a guide plate 15 has a length larger than the sum of the shortest distance between the cutter 11 and a delivery roller 13 and the feeding quantity of the sheet of recording paper 10 which is conveyed during the cutter operating time, the delivery roller 13 will not fail to send the sheet of recording paper 10.</p> |
