Abstract
PURPOSE: To reduce the production cost, number of assembling steps and installation space of the device by a method wherein the magnetic field of a ring-shaped permanent magnet common to plural pieces provided in a magnetic path is divided and the end portions of a ring-shaped leaf spring of which the end portion is divided in plurality are attracted.
CONSTITUTION: When no current is supplied to a magnet coil 4, the end portions 7a of a leaf spring 7 are attracted toward the core 2 of an armature pin 9 due to the magnetic force of a permanent magnet 3, the end portions 7a of the spring 7 being deviated. With the magnet coil 4 supplied with current, the magnetic field of the magnet coil 4 cancels that of the permanent magnet 3, so that the armature pin 9 on the spring 7 is no longer attracted toward the core 2. Accordingly, the end portions 7a of the spring 7 are released from deviation, and a print wire 8 fixed to the tip end of the spring 7 is driven and guided along a pin guide 11. Then, with the current supply for the magnet coil 4 interrupted, the armature pin 9 on the spring 7 is reattracted toward the core 2 due to the magnetic force of the permanent magnet 3.
