PURPOSE:To correctly position an electromagnet and to prevent the misregistration due to an oscillation and an impact by being equipped with an abutting positioning member corresponding to an opponent side for the electromagnet and a suppressing member composed of an elastic material at the opponent side. CONSTITUTION:An abutting positioning tool 30 is provided at the edge surface of an electromagnet 11 at the side opposite to the linking wide with a link 4. The abutting positioning tool 30 is composed of a short pillar-shaped body trapezoidal piece 31 to form a symmetrical trapezoid with the cross section and a plate 32 adhered on the upper surface. The opposite side of the abutting positioning tool 30 is composed of a V-shaped notch 21a provided at the edge surface of the position corresponding to the trapezoidal piece 31 for an upper plate 21 of a cartridge 20 and a plate spring 22 as a suppressing member fixed at the upper plate 21 near the V-shaped notch 21a. Thus, the electromagnet 11 is surely positioned for the cartridge 20 at the edge part and held while relief is suppressed by the plate spring 22. |
