ABSTRACT:
In a rotary encoder, a range of operable angle is divided into four large sections. A plurality of signal contact shoes come into contact with signal conductive portions in different combinations at individual positions within each of the large sections, and these states of contacting combinations repeat in each of the large sections. A plurality of common contact shoes correspond individually to four large sections, and each remains in contact with a common conductive portion continuously in the corresponding large section.
