Tensioning device for use with electromagnetic read/write transducing apparatus wherein a flat elongated band or strip of non-magnetic material is arranged adjacent to a plurality of read/record heads effective to support an item adapted to move between the heads and the tensioning strip and wherein the strip is lever actuated from a relaxed, released condition relative to the heads enabling easy removal and replacement due to wear or breakage into a taut condition and including means to prevent stray magnetic flux from one transducing device from interfering with the magnetic flux of another local transducing device effectively insuring a high level signal output.

Back-up pressure mechanism with tensioned elongated member

A light weight molded print hammer is provided with a pair of integrally formed and interconnected flexure members and an integrally formed rigid back-up member spaced from said flexure members, said print hammer being designed for pivotal mounting in a line priner in cooperable relationship with a solenoid and a printing position thereof, an armature carried by the molded print hammer being magnetically attracted upon energization of the solenoid to pivotally activate the rigid back-up member and to thereby translatably propel the pair of flexure members into free flight in the direction of the printing position, a metallic impact tip carried by one of the flexure members being translatably impacted into printing contact with a print media, inked ribbon and selectively positioned type character disposed in the printing position, the rigid back-up member and its spaced relationship relative to a contiguous one of the flexure members serving to absorb and to dampen the rebounding shock caused by the printing contact.
