摘要： An optical displacement sensor structure includes a plurality of light receiving elements and a plurality of optical fibers together with one light source, wherein light emitted from the one light source is efficiently introduced into the plurality of optical fibers from the circumferences of the optical fibers, well kept inside the optical fibers while transmitting therethrough, and exits out from the end face of one end portion of each optical fiber so as to impinge on each light receiving element. This structure, with only one light source, provides a plurality of optical displacement sensors thus reducing power consumption without suffering a problem of light loss and successfully enables downsizing.
