Finisher--exit pocket module for copier

An apparatus for receiving, finishing, and stacking document sheets in finished sets comprising, in combination:

• accumulator means for accumulating successively received sheets into sets for finishing, said accumulator means including clamp means for holding inserted sheets in place until moved comprising an elongated weighted member slidably mounted in a vertical direction for applying vertical pressure gravitationally along a leading edge of said inserted sheets and a fixed member fixedly mounted for supporting said inserted sheets under said leading edge;
• stacker means disposed adjacent said accumulator means for supporting accumulated sheets and for stacking finished sets, said stacker including platform means for supporting finished sets and means for controlling the height of said platform to keep a support surface positioned at approximately the level of said accumulator means' fixed member whereby said surface supports the weight of the sheets stacked in said accumulator;
• transport means for receiving individual sheets in succession and for inserting said individual sheets in said accumulator means, said transport means including vacuum belt means having negative pressure supplied thereto to hold the sheets on the belt for transporting said sheets and push-down arm pivotally mounted adjacent said vacuum belt means for disengaging away said sheets from said vacuum belt means toward said stacker means when the leading edge of a transported sheet has been inserted into the clamp means of said accumulator means;
• and
• ejector means for moving finished sets from said accumulator means onto said stacker means in a direction opposite from that in which said sheets were inserted into the said accumulator means, said ejector means including pusher means disposed, when inactivated, adjacent the leading edge of sheets received in said accumulator means, for moving, when activated, finished sets from said accumulator means onto the stacker means.
