Abstract

PURPOSE:To miniaturize an electromagnet and economize power consumption by a method wherein an L-shaped armature is turned centering around a bent angle section, and each bent piece is adsorbed simultaneously by means of an adsorbing piece mounted to a yoke plate and an electromagnet core. CONSTITUTION:When an electromagnet coil 5 is conducted, one bent piece 6a of an armature 6 is adsorbed by means of an adsorbing piece 13 and the other bent piece 6b by means of a core 14 respectively at the same time, and the desired wire head 8 is pushed and driven. A minute gap G is formed previously between the bent piece 6a and the adsorbing piece 13 under a condition that the bent piece 6b of the armature 6 is adsorbed to the core 14, thus rapidly returning the armature 6 by means of a spring 8c without being subject to the influence of remanence when conduction to the electromagnet coil 5 is interrupted.
