Abstract

PURPOSE:To prevent decrease of magnetic force from the effect of magnetic interference, by equipping a nonmagnetic case around a magnetic shield-plate on a permanent magnet having an engaging hole. CONSTITUTION:A magnetic shield-plate 3 is provided on a permanent magnet 1 having an engaging hole 1a. The plate 3, the magnet 1 and a ferromagnet plate 2 are combined by both ends 4a and 4b of a nonmagnetic case 4. On the other hand, a ferromagnetic lever 9a, projected from a ferromagnetic plate, is inserted through an engaging hole 1a and fixed in touch with a ferromagnetic lever 2a of the plate 2. At the same time, the plate 9 is engaged within an edge 4a of a case 4. Therefore, an edge 4a prevents the plate 3 from touching magnetic record cards, so that magnetic interference would never happen. This prevents magnetic interference without decreasing magnetic contact force.
