PURPOSE:To attempt the removal of jammed forms by means of single operation by providing an operating lever at the one end of a pair of pressing rollers consisting of both a fixing and a pressing roller, and slanting the pressing roller with said lever operated. CONSTITUTION:The both ends of the shaft 25 of a pressing roller 16 are slidably pressed to a fixing roller 13 by a spring 17 for carrying a form so as to be fixed. NO.1 lever 21a which can be rotated around a pivot 24 as a falcrum, is pivotally installed on the bracket 23 fixed on a frame 10, and NO.2 lever 21b with a knob 26 is fixed thereon. A lever 21 consisting of NO.1 lever 21a and NO.2 lever 21b is positioned at all time by a spring 29 at the place where a projection 30 abuts against a stopper 31. When the form is once jammed, the knob 26 is lowered by hand, followed by the downward movement of one end of the pressing roller shaft 25 so as to be slant against the other end, thereby forming a gap on the way from the fixing roller 13. This constitution thereby enables the jammed form to be removed with ease.
