Abstract
Flat, stackable printing blades for use in an impact printer head of the dot-matrix type, each blade including a conductive coil fastened within a central aperture of a conductive frame having a pair of arms resiliently connecting the coil frame to a stationary mounting portion. The mounting portion and the coil-retaining frame are split, with one of a pair of coil leads attached to each of the pair of electrically-isolated blade members thus formed, for facilitating a flow of current from one portion of the mounting tab, through one resilient arm and the coil, and thence through the remaining resilient arm to the remaining portion of the mounting tab. A stack of blades, having printing tips extending from the frame in a common direction, is arrayed to form a dot-matrix-type printhead.
