ABSTRACT:
A work to be exposed to light beams in an exposing section is fitted to an alignment table in an automatic aligning apparatus under the effect of suction caused by a suction unit. Then, cameras for optically recognizing alignment marks in the form of images are displaced to positions where the alignment marks can optically be read through wide transparent windows on an alignment table so that positions representative of displacement of the cameras are taken into position representative of the alignment marks on the work within image receiving regions recognizable by the respective cameras. The alignment table is then displaced in such a manner that the positions assumed by the alignment marks on the work are located in correspondence to preset positions in the exposing section. The apparatus is preferably used for automatically aligning a copper-plated laminar plate to be exposed with a mask film when wiring patterns on a printed wiring board are to be exposed.
