た相当の設計変更を予定したものである。The present invention was devised especially in view of the inconveniences in the prior art, and is intended to ensure the magnetic shielding effect without reducing the C1 magnetic force. The present invention is based on a permanent magnet (11a) having holes (11a) extending along the direction of the magnetic pole surface. A ferromagnetic plate (2
), and a ferromagnetic plate (3) having a hole communicating with the wire hole (11a K) is attached to the other magnetic pole surface, and a wire hole communicating with the hole (1) a at the bottom. ke) A hole having a fold-in edge flange (4) a that comes into contact with the inner circumferential surface is provided around the hole,
In addition, the previous record (3), the magnet (1), and the plate (2) are inserted into the non-magnetic case (4) in the shape of an inverted dish with a folding claw (4) b at the edge of the opening, The claw (4)b on the edge of the opening of the case (4) was folded onto the surface of the plate (2) to form an integrated support, and then placed upright on the surface of the plate (2) in the hole (1)a. The small diameter frame of the ferromagnetic rod (5) K is attached to the plate (2) and chain plate (2) in a U-shape with a washer (6).
It is inserted into the U-shaped bottom part of the case (4), and the protruding end of the inserted small diameter frame part is caulked onto the bottom surface of the core washer (6). A female stop with an engaging raised layer (4) C raised on the circumference 1IIl! edge of the contacting magnetic pole faces in the direction of contact with the chain plate (7), and the raised layer in the case (4). (4) A ferromagnetic plate that is magnetically and removably abutted on the magnetic pole face surrounded by C (abutted on the rod (5) face via the hole (11a) on one end face of the force) The rod (8) is made to protrude, and the rod (8)
) is attached to the other end of the chain plate (7) in a U-shape by inserting it into the IJ-shaped bottom of the washer (9) through the plate (7). We plan to place the end of the small diameter rod that protrudes through the insertion at a point where it will meet the male stopper that is caulked to the foot of the washer (9), and we plan to make a considerable design change that is resistant to the gist of this configuration. This is what I did.
本発明は、斜上に於ける特長ある構成としたことによつ

With the associated raised layer (4) c raised in the direction of force contact, it is possible to more reliably prevent recording errors in magnetic recording cards and the like. Moreover, by providing a fold-in edge collar (4) a that abuts on the inner circumferential surface of the hole (1) a of the case (4), the magnet surface is more perfectly exposed.
