PURPOSE:To improve the stability of a compact printer without special buffer member with a trigger electromagnet by disposing the contact of an attracting plate and a trigger after both are collided at the position out of the center of gravity of the plate and a movable core. CONSTITUTION:A coil 12 wound on a frame 11 made of plastic or the like is secured at its upper and lower parts with a yoke plate 131, and an attracting plate 16 for triggering is arranged at one side of the coil 12. In this structure, a projection piece 111 is projected on one side face of the frame 11, a contact 18 of the trigger connected to the frame 11 is provided at the side, a hole 181 formed at the contact is engaged with the piece 111, and the end 182 is bent toward the plate 16. When a connector 168 coupled to the trigger spring 17 is provided at the upper end of the plate 16, the position of the connector 168 is displaced from the center, and the contact 161 of the plate 16 and the end 182 of the contact brought into contact with the contact 161 are displaced from the center of gravity of a movable core 15 inserted into the coil 12. |
