ABSTRACT:
An interposer device for use in an impact printer for printing at condensed pitches includes an interposer plate and a striker strip attached thereto. The interposer plate is a thin spring steel plate slotted to have a plurality of chevron flexure elements symmetrically disposed across the plate. The striker strip is a thin strip of elastomeric material which is similarly slotted to have a plurality of chevron wear prevention flexure elements. Tabs on the edges of the striker strip and pockets on the surface of the interposer plate which receive the tabs provide for removably attaching the strip to the plate whereby the chevron wear flexure elements of the strip overlay the chevron flexure elements of the plate for joint deflection by impact.
