Document Type and Number:
WIPO Patent Application WO/2021/090551
Kind Code:
A1
Abstract:
Provided is a rotational positioning device capable of positioning a rotational angle at a target angle position with high precision. A rotational positioning device 100 is provided with: a housing 101; a rotational member 102 which is rotatable about a rotational member axial line 103 and at least a part of which is accommodated in the housing 101; and at least one sensor 104 installed in the housing 101. A graduated scale 105 with a plurality of scale marks is formed integrally with the rotational member 102 along the circumferential direction of the rotational member 102. The at least one sensor 104 detects an angle change amount due to rotation of the rotational member 102 on the basis of the plurality of scale marks. The rotational member 102 is positioned at the target angle position on the basis of the angle change amount.
