Modular print head

摘要

A print head for use in a dot matrix printer or the like which comprises a plurality of non-magnetic frames which carry aligned magnets, the frames being arranged in a stack with spaces formed by projecting parts on the frames between the magnets carried thereby, the printer hammers being movably located in those spaces and extending out between the frames to the printing station. A head comprising a desired number of hammers is built up by stacking the appropriate numbers of alternating frames and hammers.
