In the seat inside on vehicle manipulation body region approach detection device and the electronic equipment manipulation unit null

摘要

PPROBLEM TO BE SOLVED: To provide a vehicular operating physical approach detection device which is capable of detecting approach of an operating physical part to an operation unit with high accuracy and at low cost, and easily specifying the approaching direction, and an on-vehicle electronic apparatus operation unit using the same. PSOLUTION: The approach signal consisting of the AC waveform is received via an electrode on a seat 150 side to be capacity-coupled with a body of a seated occupant P. On the other hand, a detection electrode 42 to be capacity-coupled with an operating physical part such as a finger of the occupant P approaches is provided on the operation input part side, and the approach is detected by detecting the AC approach signal received via the detection electrode 42 by a waveform detection unit 43.
