Abstract
Official abstract text for this publication.
A rotary encoder includes a rotatable conductor and first and second signal contacts. The rotatable conductor includes a first contact finger that slides on a track which is at least a part of a circle having a center point as a center thereof; and second contact finger that slides on the track and is located at an angular position different from an angular position of the first contact finger. The first signal contact is disposed on the track, and is configured to output a signal according to an angular position of the rotatable conductor about the center point. The second signal contact is disposed on the first track, and is configured to output a signal according to the angular position of the rotatable conductor about the center point. The second signal contact is electrically independent of the first signal contact. This rotary encoder includes a small number of tracks, and accordingly has a small size.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotary encoder comprising: a rotatable conductor including: a first contact finger that slides on a first track which is at least a part of a circle having a center point as a center thereof; a second contact finger that slides on the first track, the second contact finger being located at an angular position different from an angular position of the first contact finger by about 180 degrees, a third contact finger that slides on a second track which…
