PURPOSE:To prevent breakdown of a transfer piece of a printer element of piezo-electricity driven dot printer by fixing each end of the first and second transfer pieces to a movable piece and by fixing a wire at a specific location. CONSTITUTION:Each end of the first transfer piece 6 and the second transfer piece 7 are fixed respectively to the movable piece 8 so that the main shaft K of the moment of inertia of the movable piece 8 passes the center R of rotation caused by displacement transferred from the movable pieces 4 and 5. Further, the place of installation of a wire 9 is to be so determined as the center of impact against the working point H of reaction force on the main shaft K agrees with the point R. |
