Abstract
A rotary encoder which provides multiple-bit encoded signals according to predetermined angular positions comprises a ground segment pattern having a circular arrangement of conductive ground segments and a signal segment pattern having at least one circular arrangement of different conductive signal segments corresponding to bits of each multiple-bit encode signal, which is formed in a circle concentric with the circular arrangement of conductive ground segments, and a rotary contact having a plurality of contact points making contact with the conductive signal segments in each predetermined angular position and a contact point making contact with the conductive ground segments to provide bit signals forming the multiple-bit encoded signal.
