Abstract

PURPOSE:To enable reduction of magnetic flux leaking outside and miniaturization of a permanent magnet by fitting firmly the permanent magnet on a spring located at close distance from a core. CONSTITUTION:Plural number of stock-form cores 3 are arranged on a flat board- like base 1, while a coil 2 is fitted around each core. At the tip of the core 3 and at a right angle thereto is arranged a spring 4 made of a thin plate through the intermediary of a spacer 5 and a permanent magnet 4a is fitted to the spring 4. When voltage is impressed on the coil 2, the permanent magnet 4a and the core 3, repeling each other, are separated from each other by the magnetic flux generated from the coil and, with the motion of the spring 4, a printing wire 4b is moved forward and performs a printing action. When the voltage impressed on the coil 2 lowers, the spring 4 is attracted again to the core 3 and a printing energy is accumulated.
