Claims (8)

A support member equipped with a coarse plate, a hollow rotating shaft for fixing the coarse plate, a hollow rotating shaft via a bearing, and a detector for detecting the rotational position of the coarse plate, and an inner circumferential surface of the hollow rotating shaft A rotating means interposed between the measuring shaft and a fixing means for fixing the hollow rotating shaft to the axis under measurement so as to adjust the shaft center, and a measuring surface for measuring the eccentricity of the hollow rotating shaft formed on the outer circumferential surface of the hollow rotating shaft. Encoder. 2. The detector according to claim 1, wherein the detector is configured to irradiate a laser beam from the laser light source to the light plate, and to irradiate the photodetecting device through the slit with the dark streaks on the Fraunhofer rotation formed by the slits regularly formed on the wood plate. Rotary encoder characterized in that. The rotary encoder according to claim 1 or 2, wherein the measurement surfaces are formed at both end projections of the hollow rotating shaft. 4. The rotary encoder according to claim 1, 2 or 3, wherein the fixing means comprises a pair of wedge-shaped sleeves pulled together by a screw mechanism and clamp means having a mountain-shaped sleeve. . 5. The clamp means according to claim 4, wherein the clamp means engages with the inside of the wedge-shaped sleeve and is pressed into the outer circumferential surface of the axis to be measured, and the mount with the outer circumference of the wedge-shaped sleeve and pressed into the inner circumferential surface of the hollow rotating shaft. A rotary encoder comprising a slips, wherein the outer sleeve is divided into two at an axial center position, and is provided via an adjustment distance in between. 5. A joining means according to claim 1, 2, 3 or 4, comprising coupling means for fixing the support member only in the rotational direction around the shaft center of the hollow rotating shaft and floatingly coupled in the other direction. Rotary encoder characterized in that. 7. The rotary encoder according to claim 6, wherein the engaging means includes a engaging pin protruding radially from the support member and a locking member on a fixed side engaged with the engaging pin in a circumferential direction. 7. The coupling means according to claim 6, further comprising: a flexible wire member which is disposed tangentially with respect to the circumference centered on the axis of the hollow rotating shaft, and whose intermediate portion is fixed to the support member, and a fixing bracket for fixing both ends thereof to the fixed side. Rotary encoder characterized in that. ※ Note: The disclosure is based on the initial application.
