Title:
POSITION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/131295
Kind Code:
A1
Abstract:
Provided is a position detection device that can be configured so as to be compact and can be attached to a vehicle, or the like, with a high degree of freedom. This position detection device 100 comprises a body to be detected that moves linearly in conjunction with the operation of an operation part and a plurality of sensors IC32 for outputting detection signals when the body to be detected has approached and when the body to be detected has left. The plurality of sensors IC32 are arranged in a plurality of element rows 33 in each of which one or more sensors IC32 are aligned in the row direction. The plurality of sensors IC32 are arranged such that when the body to be detected moves along a direction orthogonal to the row direction from a first shift position A(E) to a second shift position B, C, D, the signals of three or more sensors IC32 from among the plurality of sensors IC32 switch between the detection signal for approaching and that for leaving. At the second shift position, the sensors IC32 of at least three adjacent element rows 33 output detection signals.
