This invention is directed to a stack pusher apparatus which is used for pushing a workpiece such as a stack of printed circuit cards between rest locations. The pusher apparatus includes an articulated engagement unit which permits reasonable tolerances relative to the dimensions of the workpiece to be pushed or moved. In addition, a pneumatically driven control mechanism for moving the stack pusher apparatus is described.
