In an apparatus adapted to scan a lower side of an electronic component being suction-held by a suction-holding nozzle, to perform image recognition of suction-held conditions of the electronic component, this invention is intended to perform a transfer operation under a condition that the suction-holding nozzle is arranged closer to an upper surface of a base, wherein the optical path directed downwardly from the suction-holding nozzle is bended in a lateral direction by a first optical path changing member and then further bended in another direction by a second optical path changing member to allow image-sensing means to capture an image of a lower surface of the suction-holding nozzle, and the electronic component being suction-held by the suction-holding nozzle is illuminated along the lateral optical path changed by the first optical path changing member. |
