Hard copy apparatus for producing center fastened sheet sets

摘要

Electrostatographic apparatus for providing bound sheet sets suitable for folding. The sides of the sheet sets are staggered so that, upon folding, the edges become accurately aligned. Staggering is accomplished by progressively cutting the sheets shorter as they are to be positioned in the stack, and aligning the stacked sheets in a trapezoidal shape before stapling the sheets together. Aligning is accomplished by an inclined surface which makes an acute angle of approximately 32 DEG with the flat surface of the sheets. Movement of the images on the sheet is also provided to keep the outside borders on the various sheets equal.
