Abstract

PURPOSE:To achieve easy paper pickup at jamming, by providing a function detaching a pressing lever from a fixing roller with a release lever and a rotating knob compulsively turning the pressing roller externally. CONSTITUTION:A pressing lever 25 fitted with a pressing roller 18 freely rotatably is fitted to a fixed pin 25a freely rotatably, and a folding section 26 is formed at one end of the pressing lever, and a compression spring 29 is fitted with a screw 28 fixed with a support 27 energized clockwise at all times. A shaft 30 is fixed with a release lever 35 projecting a knob 34 from a cover plate 15 and positioned with a stopper pin 36, and the rotation toward counterclockwise derection can be positioned with a shaft 37. Further, a rotating knob 51 is fixed with a shaft 49 of the pressing roller 18 by a fulcrum 50, and this rotating knob 51 is located in a recess 52 formed at the side of a main body cover 2.
