Abstract

PURPOSE: To secure a printing a quality of a single operation same as that during a simultaneous operation of each printing hammer unit by a constitution wherein a magnetic flux direction of two or more printing hammer units is made mutually in opposite direction regarding an adjacent unit.
CONSTITUTION: It is constituted that a magnetic flux direction of each printing hammer unit 3 itself passing through a magnetic circuit of each hammer unit 3 in a printing head is mutually made in reverse direction. When these printing hammer units 31, 32, 33 are arranged on a joint yoke 1 and they are operated simultaneously, each leak magnetic flux (chain line arrow head) flows to the unit 32 passing through the yoke 1, and at the unit 32 position, magnetic flux directions are all in a same direction and the magnetic flux quantity is added by the corresponding share and a magnetic attractive force is increased. When an armature 42 is in a saturation state, even if the magnetic flux is increased, only a slight variation is generated in the magnetic attractive force against the armature 42.
