    摘要： 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.

    摘要： An encoder includes a scale member provided on one of two bodies which are relatively rotated and have gratings arranged in a relative rotating direction and a light irradiator for irradiating a first region with beams. A diffracted image of the first region is projected on a second region of the scale member. The encoder further includes a detector for detecting the beams from the second region. The relative rotation of the other body is detected based on a detected result thereof. A scale whose relative rotation to a rotation detecting device is detected by being irradiated with the beams from the encoder. The scale includes a base member formed with a grating having surfaces inclined to incident beams. In addition, a driving system causes relative rotation between the two bodies. This system includes a device for relatively rotationally driving the two bodies and a controller for controlling a driving condition of the driving device. A motor unit includes a motor module having rotation of its body detected by a result of a light irradiator and rotary shaft provided with a scale member. This unit further includes a supporting device for integrally supporting the body, the light irradiator and the detector.
