Abstract
A rotary encoder is incorporated in an annular space formed between a hollow rotating shaft and an encoder case. The rotary encoder has an annular printed wiring substrate, a plurality of mounting substrates that are outward from the printed wiring substrate in the radial direction and are arranged in the circumferential direction, and inter-substrate wiring cables bridged between the printed wiring substrate and each of the mounting substrates in the radial direction. Power supply to the mounting substrates and signal transmission and reception between the mounting substrates can be accomplished without routing around the wiring cables. It is possible to achieve a rotary encoder that is suitable for being incorporated in a narrow annular space.
