PURPOSE:To prevent a form from entangling due to the forming of a loop in the form, by pulling the form downward by mean of a guide bar to smooth a crease in the form when the crease approaches rollers. CONSTITUTION:Forms 25, 26 which are folded with a carbon paper 24 being held therebetween and are set on a form bed 20, are pulled to be held between a roller 10 and a retaining roller 11, and the carbon paper 24 is wrapped around a carbon paper wind-up form 17 before a motor being driven. The forms 25, 26 are transferred while being held between the rollers, and then are printed. Accordingly, although the forms are made closely contact together, a form retainer 12 is made into contact with the roller 10 by its weight to separate the forms 25, 26 from each other by means of both retaining faces of the retainer 12. A guide plate 22 having a rubber plate containing therein magnets made of feromagnetic materials, prevents the forms from zigzagging. When crease 27 approaches the roller 10, the forms 25, 26 are pulled by a guide bar 23 to be prevented from deflecting, thereby the forms are vertically pulled even if the crease 27 approaches. |
