Abstract
A sheet-fed printing apparatus includes a delivery section covered with a discharge section cover formed with an opening sized to allow a printed sheet to pass through. Successive printed sheets released from a chain delivery collide against a pair of first sheet-trapping elements in a closed position, and are stacked on a delivery table, with the leading edges of the printed sheets aligned with each other. If a printed sample is needed, an operator opens the first sheet-trapping elements to an open position. In synchronism with the first sheet-trapping elements, a pair of second sheet-trapping elements move to a closed position. A subsequent printed sheet passes through the opening, and stops on the second sheet-trapping elements. Thus, the printed sheet is stopped, with the leading edge thereof projecting outwardly of the sheet-fed printing apparatus. In this state, the operator can take out the printed sample without opening the delivery section cover.
