Impact type printer

Abstract

Abstract PURPOSE:To obtain an impact type printer capable of returning magnetic ink on the tip of a printing wire by using a system in which a magnetic field formed in the gap between yokes by which magnetic ink is sucked up from an ink container and directed to the printing wire is electrically reduced or annihilated. CONSTITUTION:When the power source of the printer is broken, a holding electromagnet 7 and a stopping electromagnets 9a and 9b are unexcited in such a way as to cause magnetic ink 3 held in the gaps between stopping yokes 8a and 8b and between stopping yokes 8c and 8d to drop onto an inclined face 1c under its own weight. The magnetic ink 3 which flows into the gap between holding yokes 5 and 6 along the inclined face 1c and the magnetic ink 3 already held go down under their own weights and return into the ink container 4.
