ジ式印字ヘツド。 A plurality of printing head units are arranged in an annular manner on a base, and the printing head unit consists of a U-shaped magnetic core, an electromagnet formed by winding a coil around one end of the magnetic core, and a permanent magnet inserted in the middle of the magnetic core. A magnet, an armature attached to the other end of the magnetic core via a first flexible member and having a printing wire at its tip, and a second armature fixed to the magnetic core and inserted into a hole provided in the armature. It becomes a flexible member,
A spring charge type printing head characterized in that the hole is formed in a size that allows the second flexible member to be flexibly deformed only for a predetermined stroke from the standby position of the printing wire.
