<p>PURPOSE:To make it possible to insert a roll copy paper to a paper supply part easily, constituting the paper supply part by a paper supply axis, a tension roller, a pair of stopping rollers, a pair of driving rollers, and so on. CONSTITUTION:Stopping rollers 30 and 31 are installed in the front side of driving roller 32, and upper stopping roller 30 is movable vertically and rotatabily freely, and lower stopping roller 31 can be rotated and driven in the arrow direction synchronously with driving roller 32. Tension roller 20 is provided rotatable at the tip of tension arm 21 and describes an arc in the front side of stopping rollers 30 and 31 while uniting with oscillation of tension arm 21 and is movable vertically. Tension roller 20 and stopping rollers 30 and 31 are lifted automatically for insertion of roll copy paper 16, so that the insertion work can be easy. A proper sag is given to copy paper 16 by operating and releasing the brake means provided on paper supply axis 17 while interlocking with vertical movement of tension roller 20, so that copy paper 16 can be inserted very smoothly.</p> |
