ABSTRACT:
A paper feed device for a copying machine, in which paper jamming at the copying paper cutting mechanism is effectively prevented is provided. This paper feed device for a copying machine comprises a feed reel for supporting a copying paper wound thereon in a roll-like form, a paper feed roller intermittently driven and rotated to take out the copying paper from the feed reel, an introduction roller disposed on the introduction side of a transfer passage for delivering the copying paper to copying treatment zones in the copying machine, and a copying paper-cutting mechanism disposed between the paper feed roller and the introduction roller to cut the copying paper taken out of the feed reel into a prescribed length. The paper feed device further comprises a paper jamming-preventing mechanism for stopping the front end of the copying paper, which is present at the cutting position when the operation of the paper-cutting mechanism is completed, at a position slightly retreated from the cutting position and making the front end of the copying paper stand by for the next copying operation at this retreated position.
