Abstract
1398955 Print hammer mechanisms SUWA SEIKOSHA KK and SHINSHU SEIKI KK 21 Feb 1973 [24 Feb 1972 30 March 1972] 8536/73 Heading B6F In print hammer mechanism comprising a permanent holding magnet 103 common to a plurality of spring-biased hammers 101 and energizable release coils 104, means are provided to compensate for the alterations to the magnetic circuit caused when a hammer is released and which cause the release of other hammers to require a greater opposing field. The compensation may be achieved by re-energizing the release coil after its respective hammer has been actuated, or by maintaining the initial current until a print cycle has been completed. The coil 104 may comprise two parts, one part 104 2 representing a reset coil. Alternatively a single coil may be energized in reverse sense to act as a reset coil.
