Title:
MAGNETIC DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2017036949
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic detection device capable of detecting motion in two directions independently with high accuracy by one magnet.SOLUTION: The magnetic detection device has: a magnet 120 rotated around a first axis of rotation L1 by an operation unit and tilted around a second axis of rotation L2; a rotation detection sensor 140 that is a first magnetic detection unit for detecting a change in a magnetic field around the first axis of rotation L1 of the magnet 120; and a tilt detection sensor 160 that is a second magnetic detection unit for detecting a change in a magnetic field around the second axis of rotation L2 of the magnet. The first axis of rotation L1 and the second axis of rotation L2 intersect each other at right angles, and the rotation detection sensor 140 and the tilt detection sensor 160 constitute the magnetic detection device so as to independently detect the motion of the rotation operation and titling operation of the magnet 120.SELECTED DRAWING: Figure 3
