CONSTITUTION:In order to impart tension to paper for the purpose of feeding said paper to both directions, a cam 17 is rotated and a slide plate 10 is slid to the upward direction shown by the arrow A. At this time, a drive shaft 2 and a hold shaft 8 are moved in slots 9a, 9b in an up-and-down direction and the position of a tractor 7 is raised to impart tension to the paper 5. The plate shaped rear stay 18 connected to left and right frames 9 is provided so as to coincide the angle thereof with the ridge line of a platen 6 and can also achieve the function of the guide of slip paper 19. A gap 18a is provided to the lower part of the rear stay 18 and forms a paper inlet port at the time of unidirectional feed. |
