<p>PURPOSE:To feed photosensitive paper surely by installing a sheet paper feeding mechanism made up of a one-way clutch, paper feeding rollers and separating pawls, and detaining to the opening of a copier. CONSTITUTION:A feeding mechanism 24 made up of sheet separating pawls 23a, 23b, an axis 25, paper feeding rollers 26a, 26b and a handle 27 is installed in front of a paper feeding cassette in the feeding direction of paper. The sheet P is pushed upward by a middle plate 36 energized by a spring 33. A paper feeding opening of the cassette 21 is made oppposite to an opening 30 of a copier 22, and fixed with an engaging pin 39 and an engaging body 40. When the handle 2 is turned, an engaging spring 44, an engaging piece 45 and the axis 25 are engaged together, and the rollers 26a, 26b rotate with the axis. The paper is separated surely sheet by sheet by separating pawls and fed to rollers 31, 32 of the copier body. When the handle 27 is turned further, the engaing piece 45 is disconnected from a concave part 43 and the axis runs idle. By this way, the paper is fed surely sheet by sheet avoiding fogging by every rotation of the handle.</p> |
