Abstract
A printing apparatus having a paper positioning plate swingably supported and having two positions in operation. The first position temporarily stops the carrying of an edge of a paper sheet by engaging the edge. The second position allows the paper sheet to be freely carried. The portion of the paper positioning plate which engages the edge of the paper sheet is curved as an arc having its axis on the axis of swing of the paper positioning plate. Thus, the swinging motion of the paper positioning plate does not create a strong frictional force at the edge of the sheet of paper and hence no paper particles are produced.
