ANGLE DETECTION DEVICE, ROTATION AMOUNT SPECIFYING UNIT AND ROTATION DRIVING UNIT

Title:

ANGLE DETECTION DEVICE, ROTATION AMOUNT SPECIFYING UNIT AND ROTATION DRIVING UNIT

Document Type and Number:

WIPO Patent Application WO/2019/059173

Kind Code:

A1

Abstract:

Provided is an angle detection device which is capable of reducing manufacturing time and labor while suppressing an increase in size. The present invention is provided with: a first rotating body (120); a second rotating body (122); a first transmission mechanism (111) which decelerates the rotation of the first rotating body (120) and rotates the second rotating body (122); a first angle detection unit (Ds) which detects the rotation angle of the first rotating body (120); a separate second angle detection unit (Dm) which detects the rotation angle of the second rotating body (122); and a processing unit (40) which specifies the rotation speed (Rs) of the first rotating body (120). The processing unit (40) specifies the rotation speed (Rs) while dynamically changing a specifying condition for specifying the rotation speed (Rs) in response to the detected rotation angle of the second rotating body (122) and a numerical value which is determined according to the detected rotation angle of the first rotating body (120) and a reduction ratio (G1) of the first transmission mechanism (111).
