Abstract

PURPOSE: To apply correct tension and perform smooth paper feeding by removing the slack of a roll sheet produced between a loading means for the roll sheet and a conveying means which bites the sheet end drawn therefrom by means of a rotating force accumulating means and releasing means in the direction of winding the sheet.
CONSTITUTION: To drawn out a roll sheet 4, a spring 23 is tightened as the pin 18c of gear 18 is turned about axis 26 from the position illustrated and until it abuts against the stopper piece 31b of a stopper 31 and the elastic force of this is energized according to an angle θ. The rotating habit toward the dotted arrow is given to the gear 18 by the energizing elastic force thereof and the rotating habit rewinding this is exerted to the roll sheet 4. When the cover is closed in this state, an actuating lever 43 is turned by a spring 44 and a stopping lever 41 is also turned clockwise to release the geat 18, then the gear 18 is rotated in the dotted arrow direction by the energizing elastic force of the spring. The gear 17 is also rotated in the dotted arrow direction ot rewind the slaskened portion of the roll sheet 4 thereby giving tension to the sheet.
