ABSTRACT:
An electronic part mounting apparatus enables reduction of the time required for attracting and mounting of a part and is reduced in cost and occupies comparatively little space as composed to conventional electronic part mounting apparatus. The mounting apparatus comprises a mounting head, an attracting nozzle mounted for vertical movement, an image pickup camera mounted in parallel to the attracting nozzle, and a mirror unit mounted for horizontal movement and including a plurality of reflecting mirrors disposed in opposing relationship to lower ends of the attracting nozzle and camera to define a light path from an electronic part attracted to the part attracting nozzle to the camera. When the attracting nozzle operates to attract or mount an electronic part, the mirror unit is moved horizontally away from a position below the attracting nozzle, but when an image of the electronic part is to be picked up by the camera, the mirror unit is positioned just below the attracting nozzle to establish the light path.
