形成されたことを特徴とするドツト印字ヘツド。[Claims for Utility Model Registration] The armature on the leaf spring is attracted to the core of the electromagnet by the magnetic flux of the permanent magnet, and by exciting the electromagnet, the magnetic flux of the permanent magnet is canceled and the armature is moved by the reaction force of the leaf spring. The printing wire attached to the armature is moved to protrude from the guide frame, and a residial sheet is interposed between the leaf spring and the core of the electromagnet, and a detection coil for detecting the magnetic flux of the electromagnet is installed. What is claimed is: 1. A dot printing head, characterized in that the detection coil is formed in the shape of a sheet coil on the surface of a reciprocal sheet corresponding to each core of the electromagnet.
