Title:
変位検出装置及びこれを備える操作装置
Document Type and Number:
Japanese Patent JP7033747
Kind Code:
B2
Abstract:
To provide a displacement detector for detecting the displacement of an operator such as a dial and a shift lever, and a handling device equipped with the displacement detector.SOLUTION: A displacement detector 70 comprises an electro-conductive movable detection object 71 that moves in conjunction with the displacement of a dial 20, and an electro-conductive stationary detector 90 contactlessly arranged in the vicinity to the movable detection object. The stationary detector includes a pattern conductor 91a constituting a detector connected to the ground terminal of an electrostatic IC 80, and pattern conductors 91b-91e constituting detectors connected to the other input terminals of the electrostatic IC. The movable detection object includes projections 74a-74e constituting detection objects arranged facing the pattern conductors 91a-91e. The electrostatic IC detects the displacement of the dial on the basis of electrostatic capacitance between the movable detection object and the stationary detector.SELECTED DRAWING: Figure 3
