    • There is provided a position control apparatus and method for a table member which is capable of controlling the positioning of the table through very small displacement thereof, to thereby prevent the position of the table from deviating even when a disturbance such as vibration is applied to the table. A table member is movable relative to the base member in a predetermined direction. A threaded shaft is rotatably mounted on a base member and elastically deformable when twisted. A motor is coupled to one end of the threaded shaft, for rotating the threaded shaft to displace the table member. A pressurizing and fixing member is arranged in the vicinity of a location where the motor is coupled to the threaded shaft, for pressurizing the threaded shaft to be fixed in position.
    • 提供了一种用于台面构件的位置控制装置和方法,该位置控制装置和方法能够通过非常小的位移来控制工作台的位置,从而即使当诸如振动的扰动施加到桌面上时也能防止工作台的位置偏离 表。 工作台构件可相对于基座构件在预定方向上移动。 螺纹轴可旋转地安装在基座构件上并且当扭曲时可弹性变形。 电动机联接到螺纹轴的一端,用于旋转螺纹轴以移动工作台构件。 加压固定部件设置在电动机与螺纹轴联接的位置附近,用于加压被固定在位的螺纹轴。
