ABSTRACT:
A position encoder for providing signals that reflect the position of an object is contained in a housing which can be rotated back and forth to update the encoder. The encoder comprises a sun gear and a planet gear, and these gears are connected to an object. From the rotation of these gears, those signals that reflect the position of the object are generated. Rotating the case causes the gears to rotate relative to each other and to sensors which produce the signals. By rotating the case back and forth between reference and update positions, those signals are generated and the encoder is thereby updated without moving the object.
