Zusammenfassung: | To provide an external force detection device that can change resolution and a measuring range.SOLUTION: In an external force detection device 1, a cantilever 2 is formed of an elastic member, is arranged to extend to a lower side in a container 10 while being supported at an upper side, and is provided with a movable electrode 41 at the lower side. A stationary electrode 42 is provided at a position opposite to the movable electrode 41, is changed in capacity according to deflection of the cantilever 2, and forms variable capacity Cv to change the frequency of a frequency signal output from an oscillation unit 60. A container holding unit 5 changes the direction of gravity acting on the cantilever 2 to change an angle to hold the container 10 in order to change a reference angle formed by the movable electrode 41 and the stationary electrode 42 viewed from a support position of the cantilever.SELECTED DRAWING: Figure 1
【課題】解像度や測定範囲を変更することが可能な外力検出装置を提供する。【解決手段】外力検出装置1において、カンチレバー2は、弾性材料により構成され、上部側が支持された状態で、容器10内を下方側へ伸びるように配置され、その下部側には可動電極41が設けられる。固定電極42は、可動電極41に対向する位置に設けられ、カンチレバー2の撓みに応じて容量が変化し、発振部60から出力される周波数信号の周波数を変化させる可変容量形成Cvを形成する。容器保持部5は、カンチレバー2に作用する重力の方向を変化させることにより、その支持位置から見た可動電極41と固定電極42とのなす基準角度を変化させるために、容器10を保持する角度を変化させる。【選択図】図1 |
