Title:
ROTATIONAL ELECTRONIC COMPONENT AND ROTATION ENCODER
Document Type and Number:
WIPO Patent Application WO/2016/158655
Kind Code:
A1
Abstract:
This rotation encoder is provided with: a shaft which is rotatable around an axis, and which is movable along that axis; a restriction member which restricts the rotation angle of the shaft; an encoder mechanism which detects the rotation direction of the shaft and the rotation angle thereof; and a switch mechanism which is pressed by the shaft moving along the axis of the shaft. The shaft is provided with an outer circumference surface that includes a plurality of convexities and concavities arranged in the circumferential direction. The restriction member is provided with a contact part which is contactable with the outer circumference surface of the shaft. The contact part is in contact with a convexity on the outer circumference surface of the shaft in an elastically energized manner, and is engaged with a concavity in the outer circumference surface of the shaft, thereby restricting the rotation angle of the shaft.
