Claims

[Scope of claim for utility model registration] (1) 1 along the insertion direction of the key on the key body
A magnet insertion part such as a recess, a through hole, or a groove as described above is formed, and a plurality of permanent magnets having magnetic poles of N pole and S pole are arranged and fixed in the magnet insertion part with an appropriate width and arrangement pitch to form a P pole. (P is an integer of 2 or more) A magnetic pole formed by forming a permanent magnet for magnetic pole information or fixing a permanent magnet for magnetic pole information formed by magnetizing multiple N and S poles at an appropriate magnetization pitch An information part is formed, and a permanent magnet forming the magnetic pole information part is made of neodymium, boron, and iron-based magnets,
A key having magnetic pole information, wherein a rust-preventing protective film is formed on the surface of the permanent magnet exposed from the key body to prevent rust from forming on the permanent magnet. (2) When the magnetic pole information part is formed of a plurality of permanent magnets, there are a plurality of magnet insertion parts for inserting, arranging, and fixing the permanent magnets, and these plurality of magnet insertion parts are free. The scope of claim for utility model registration (1) is formed at equal intervals.
Key with magnetic pole information listed in ). (3) The magnet insertion portions formed at unequal intervals have magnetic pole information as described in claim (2) of the utility model registration claim, in which the magnet insertion portions are formed with different widths along the key insertion direction. Key. (4) The magnetic pole information permanent magnet formed on the key body by magnetizing multiple N and S poles is a practical magnet in which the N and S poles are formed with pitches of irregular width. A key having magnetic pole information as set forth in claim (1) of patent registration. (5) The above-mentioned permanent magnet for magnetic pole information is one in which a plurality of magnetic poles for magnetic pole information are magnetized after being inserted and fixed into the magnet insertion part by molding means of a neodymium/boron/iron-based resin magnet. A key having magnetic pole information as described in claim (1) of the utility model registration.
