    • A force measuring apparatus includes first fixed electrodes disposed in one direction in one plane so as to be distant from each other; second fixed electrodes disposed in the one direction in a plane opposed to the one plane, so as to be distant from each other and opposed to the respective first fixed electrodes; and movable electrodes movable in the one direction. The apparatus further includes a force receiving portion to receive an external force and thereby move the movable electrodes in the one direction so as to change the overlapped area between each first fixed electrode and the corresponding movable electrode and the overlapped area between each second fixed electrode and the corresponding movable electrode. The apparatus measures the magnitude of the force applied to the force receiving portion based on the changes in the capacitance values of the capacitance elements.
    • 力测量装置包括:在一个平面中沿一个方向设置成彼此远离的第一固定电极; 第二固定电极,沿与所述一个平面相对的平面沿所述一个方向设置成彼此远离并与所述第一固定电极相对; 以及可沿一个方向移动的可动电极。 该装置还包括受力部分,用于接受外力,从而沿一个方向移动可动电极,以便改变每个第一固定电极和相应的可移动电极之间的重叠区域,以及改变每个第二固定电极和 相应的可动电极。 该装置基于电容元件的电容值的变化来测量施加到受力部的力的大小。
