POSITION LOCATING APPARATUS EMPLOYING MULTIPLE PROJECTING LAMPS

摘要

Position-locating apparatus projects light from an array of lamp devices onto one or more selected locations on a support member to indicate automatically that a correspondingly-selected device is to be positioned at each illuminated location, typically for assembly onto the support member. The designation of the selected device lights a selected lamp element of the array for illuminating each position through an optical mask. Each lamp projects light over an area on the support member that partially overlaps the area which one or more other lamp elements can illuminate, but only a single lamp illuminates windows in a single unique portion of the mask.
