Abstract

A stapler/stitcher apparatus is illustrated for binding sets of copy sheets produced in a copier. The apparatus is of the semi-active type wherein both the driver force and active clinching ears are utilized to effect the stapling operation. In Figure 1, a driver element 1 is actuated by a suitable power source to drive a staple S through a set of copy sheets C positioned upon a clamping surface 2. Two pivoting clinching ears 3, 4 are mounted in a spring-loaded, movable frame 5 and are caused to rotate by a stationary actuator 6 when the frame is lowered under action of the driver. In Figure 1, the legs of the staple are shown driven against the ears 3, 4 and further driving action causes the legs to bend by the continued movement of the driver element 1 against the ears and the pivoting action of the ears as the frame 5 is lowered as shown in Figure 2. The downward movement of the frame is approximately half the thickness of a copy set.
