ABSTRACT:
A low height-profile rotary optical encoder having an improved coupling structure for coupling the code disc to the shaft for which positional information is desired wherein the coupling structure includes a coupling member having a shaft portion and an integral flexible coupling portion, a bearing structure for rotatably supporting the shaft portion within the encoder, the bearing structure and shaft portion each having a length which is substantially equal to one another, and the height of the encoder optics can be greater than the height of the bearing structure, and a base which is adapted to support the bearing structure, the shaft portion of the coupling member and the encoder optics in a common transverse section of the encoder and to house the flexible coupling portion of the coupling member wholly within the base.
