Abstract
PURPOSE: To provide printing hammer requiring no waiting time, in which a permanent magnet is provided on a part of an iron core and an armature is freed from magnetic effect when a coil is energized, and which is capable of performing high- speed printing by utilizing the repelling force of a spring.
CONSTITUTION: Permanent magnet 3 is fitted on a part of core 1'. When current flows in coil 2', armature 6' is attracted onto end surface 1a of core 1' by the magnetic attraction of permanent magnet 8. When current flows in coil 2' in this condition, a magnetic flux is set up inside core 1' in the direction opposite to magnet 8, and their attracting forces cancel. As a result, armature 6' is separated from core end surface 1a' by the repelling force of spring 5', moves in the direction of arrow B, and performs printing. When coil 2' is cut off, armature 6' is attracted to core end surface 1a' again, so that printing is stopped.
