Title:
ROTATION MOVEMENT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/002451
Kind Code:
A1
Abstract:
Provided is a rotation movement detection device that is capable of detecting, via a single magnet and without contact, movements in two directions. A lever switch device (1) comprises: a magnet (50) which rotates around a third rotation axis (L3) and generating a magnetic field (500) plane symmetrical with respect to a plane (503) containing the third rotation axis (L3); a turn detection sensor (80), arranged on the arrangement surface (101) of a base plate (100), for detecting the magnet (50) rotation angle (θ); a first dimmer detection sensor (91) for detecting the approach and separation between the magnet (50) and the arrangement surface (101) due to relative movement therebetween, said first dimmer detection sensor (91) being disposed at the intersection (911) between a straight line (506), which passes through the intersection (801) between the third rotation axis (L3) and the arrangement surface (101), and the outer periphery of an image (505) of the magnet (50) projected onto the arrangement surface (101); and a second dimmer detection sensor (92) for detecting the approach and separation between the magnet (50) and the arrangement surface (101), said second dimmer detection sensor (92) being disposed at a position that is plane symmetrical to the first dimmer detection sensor with respect to the plane (503).
