PINCHING DETECTOR
To provide a pinching detector having a simple structure and capable of reducing a dead zone at its end part.SOLUTION: A pinching detector is configured to detect whether to pinch an object between a first member and a second member, and comprises: a waveguide that is provided in one or both of the first and second members, and elastically deforms when the object is pinched; a first sonic wave input unit provided on one end side of the waveguide, and configured to input sonic waves to the waveguide; a first signal acquisition unit provided on the one end side of the waveguide, and configured to convert the sonic waves propagating in the waveguide into electrical signals, to generate response signals; and a signal processing unit configured to execute trend removal processing and Fourier transformation for the response signals to generate position response, and when a peak exists in the position response, determine that the object is being pinched.SELECTED DRAWING: Figure 1
【課題】構造が簡単で端部の不感領域の少ない挟み込み検出装置を提供する。【解決手段】本発明の挟み込み検出装置は、第１部材と第２部材との間への物体の挟み込みを検出するものであり、第１部材と第２部材の一方または両方に設けられ物体が挟み込まれたときに弾性変形する導波路と、導波路の一端側に設けられ導波路に音波を入力する第１音波入力部と、導波路の一端側に設けられ導波路を伝搬する音波を電気信号に変換して応答信号を生成する第１信号取得部と、応答信号にトレンド除去処理とフーリエ変換を施して位置応答を生成し、位置応答にピークが認められる場合に物体の挟み込みがあると判定する信号処理部とを備える。【選択図】図１
