Abstract

PURPOSE:To change over a magnetic flux and enhance the printing speed of an electric typewriter, a printer for a computer or the like by using a high- frequency ferrite for a magnetic circuit in an electromagnetic driving part for a printing hammer. CONSTITUTION:An attractable piece 16 is attracted to a leg 11 of a yoke 10 by the magnetic force of a permanent magnet 13, and elastic energy for printing is stored in a coil spring 17. When a current is passed in a solenoid 12, the resulting magnetic flux cancels the magnetic flux of the magnet 13, a wire 6 is driven in the direction of an arrow Q by the spring 17, and printing is performed through the hammer. Accordingly, generation of an eddy current is prevented, enabling a high-speed printing.
