Claims

[Scope of utility model registration request]

(1) A plurality of magnetic detection elements are arranged in a plane at predetermined intervals, and a plurality of magnets are arranged to face each of these magnetic detection elements and move relative to the magnetic detection elements. In a device that separately detects approach, a plate-shaped object made of a magnetic material is placed parallel to the plane on which the magnetic detection elements are arranged, and a magnetic detection element is placed between the plate-shaped object made of a magnetic material and the magnet. A hole is provided at a position facing the magnetic sensing element of the plate-like object made of the magnetic material, and a hole is formed on the side opposite to the magnetic sensing element of the plate-like object made of the magnetic material. A magnet detection device characterized in that a second magnet is attached in contact with the magnet.

(2) Utility Model Registration Scope of the Claim The magnet detection device according to claim 1 is characterized in that the first magnet and the second magnet are arranged so that their polarization directions are the same and their polarities are also the same. McNet detection device.
