PURPOSE:To achieve stabilization of printing operation and prevention of a wire from breaking by preventing the wire from deformation, by connecting an armature to the wire with a joint capable of being rotated. CONSTITUTION:A wire 3 is connected to an armature 2 via a joint 2a. When the armature 2 is operated, though the armature 2 is rotated centering its fulcrum 2b, the wire 2 is simultaneously rotated centering the joint 2a, and keeps a position so as to be incident always rectilinearly into a hole 4a of a sub-guide 4. Therefore, since a rectilinear incident position of the wire 3 when the armature 2 is operated, coincides with the hole position of the sub-guide 4, the wire 3 is not deformed, and motion of the wire 3 becomes smooth owing to reduction of friction force between the wire 3 and the sub-guide 4. Stabilized printing operation can be obtained thereby and besides, the wire 3 is prevented from breaking. |
