PURPOSE:To lessen the loss of the flying force given by a clapper, by a method wherein the base end parts of plural wires are arranged on a concentric circle at regular intervals and the wires are linearly gradually converged with guides. CONSTITUTION:The base end parts 116 of wires 102 are arranged on a concentric circle at regular intervals, held with a guide 120, conducted with guides 122, 124 and let to form the dot line lined up in one line on the final recording surface. The wire 102 does not receive the loss of momentum like that when it is compulsorily bended with a guide. Then, the magnetic driving part can be miniaturized and lightened and the inertia can be lessened. |
