Optical encoder device for small-sized motor and method of producing the same

摘要: An optical encoder device for a small-sized motor has code wheel attached to shaft which extends the exterior of through bearing accommodated in bearing-retaining section provided on an end bell motor, and board photosensor module is mounted such that modulation track portion positioned disposed gap module. While spacer sandwiched between board, spacer, are fixed together by soldering pair terminals printed wiring board. The generally U-shaped structure so as allow fitting position thereof from direction orthogonal shaft.
