| 摘要 |
An optical encoder device (100) comprises an optical encoder for detecting codewheel/codestrip positions, an optical encoder housing of accommodating the optical encoder, a first tapered guidepost (103) protruding from a sidewall (102) of the optical encoder housing, said first guidepost (103) having a star-shaped cross-section and being arranged adjacent to the optical encoder, and a second tapered guidepost (104) protruding from the sidewall (102) of the optical encoder housing and extending substantially parallel to the first guidepost (103), said second guidepost (104) having a diamond-shaped cross-section and being arranged remote from the optical encoder. |
