Abstract: PURPOSE:To position and secure a precision part with high accuracy and reproduction by securing the precision part with a screw through a rotary force absorbing board to be guided through slide pins thereby absorbing the rotary force of screw. CONSTITUTION:A precision part 5 mounted on a work stage 1 is positioned through a pushing pin 3 toward the securing/positioning pins 2, 2 the a screw 15 is turned to lower said part 5 and a rotary force absorbing board 11 is lowered along the slide pins 6... while compressing the coil springs 8... to push the precise part 5 toward the work stage 1 at the projection 11a in the center of underface.

Abstract: PURPOSE:To obtain the device which is small in size and weight, reduced in power consumption, and remotely controlled by varying a 2nd relay lens system by an ultrasonic wave motor without moving an image pickup element. CONSTITUTION:As a 3rd ultrasonic wave motor is driven, an external cylinder 62 rotates on an axis parallel to an optical axis 11 about a casing 9. At this time, an intermediate cylinder 61 and an internal cylinder 60 also rotate in one body and the center of the internal diameter of the external cylinder, i.e., the center of the external diameter of the intermediate cylinder moves on a track A. When the center of the intermediate cylinder is at a point A1, a 2nd ultrasonic wave motor is driven to rotate the intermediate cylinder, and then the optical axis 11 changes as shown by a track B. Therefore, the position of the optical axis 11 of a 2nd relay lens system 3 is optionally settable within a range determined by the quantities of eccentricity of the centers of the internal diameters of the external cylinder and intermediate cylinder with the centers of the external diameters. Further, a 1st ultrasonic wave motor is rotated by a proper angle to shift the 2nd relay lens system in the image formation position in the direction of the optical axis 11 within the length range of a male screw 16.
