PURPOSE:To simplify assembling by forming an integral construction of a main frame consisting of a pair of right and left side frames, a base and a paper guide and then, attaching a pinch roller unit to the main frame. CONSTITUTION:A main frame 62 made of die-cast aluminum is integrally formed with a pair of right and left side frames 63, a base 64 and a paper guide 65. Further, integrally installed in the paper guide 65 are, in the back of guide 86 as an installation place of a pinch roller unit 46, a receiver 81 into which one end of an operation shaft 50 fits and freely rotates therein; in the right side frame 63, a receiver 82 into which a boss 56 of a middle lever 51 fits and freely rotates; a stopper 84 which stops slipping of an operation lever 52 from a supporting shaft 83; receivers 86 that receive coil springs 85 that fit into the back of roller arms 49; and roller guides 88 that guide the both sides of the roller arms 49. |
