Abstract

PURPOSE:To enable reduction of the leaking flux of a permanent magnet and miniaturization thereof by providing the permanent magnet attracting a spring assembly adjacently to the assembly. CONSTITUTION:On a flat board-like base 1 are arranged plural number of stock- form cores 3, each of which is fitted with a coil 2 around, and a ring-like permanent magnet 10 is fitted to the frontage of the coil 2. At the tip of the core 3 a spring 4 made of a thin plate is arranged through the intermediary of a spacer 5, while a printing wire 4b is fixed to the spring 4 through the intermediary of a plate made of a magnetic material. Voltage being impressed on the coil 2, the coil 2 is excited and the electromagnetic forces opposing each other and having reverse polarities are generated in the ringlike permanent magnet 10, thus the spring 4 being separated by the spring force thereof.
