    摘要: There is disclosed a rotation axis fine adjustment apparatus for finely adjusting rotation of a mounting portion rotatably mounted on a rotation axis with respect to a base portion through a fastening frame by suitably fastening and finely adjusting the rotation axis. It comprising an outer tube inserted in and fixed to the mounting portion with its end portion projecting outward; an intermediate hollow axial body formed at its outer peripheral surface with a flange portion and at its inner peripheral portion with a female thread portion, and inserted into inside of the outer tube and concentrically secured to the outer tube by screw means with the flange portion abutted against the end portion and other outer tubes kept being spaced apart from the outer tube; a fastening intermediate hollow axial body rotatably attached to an inner side of the outer tube at outside of the intermediate hollow axial body, and fixed at its one end with a fastening control handle; and a fine adjustment axial body formed with a male thread portion for being in threaded engagement with the female thread portion and reciprocally movably attached to an inner side of the intermediate hollow axial body in order to finely rotate the mounting portion, and coaxially fixed at its one end with a fine adjustment control handle with respect to the fastening control handle.

    摘要: A displacement measuring device, using an incremental code, which includes a coding member (22) resting on the object (21) to be measured and having a coding section for generating such signals that a sensing element can discriminate the signals as 0 or 1, sensing means (25A, 25B) disposed to sense the coding section of the coding member for producing sensed signals in response to the displacement of the coding member (22), and rectangular wave-converting circuits (27A, 27B) for receiving and converting the sensed signal into rectangular wave signals. A clock pulse generator (28) is provided in the device for generating a clock pulse with a higher repetition-frequency than the repetition-frequency of the sensed signal. An edge detector (29) receives the clock pulse from the clock pulse generator (28) and the rectangular wave-signal from the rectangular wave-converting circuits (27A, 27B) and then delivers, as an output pulse, the clock pulse substantially coincident with at least one of the leading edge and the trailing edge of the rectangular wave-signal. A counter (30) counts the output pulses from the edge detector and a display (31) indicates the counted value. With such an arrangement, an incremental displacement measurement can be made without a differentiating circuit and an averaging circuit.
