Abstract:
1. An attraction state inspection device comprising: a diffusion member that is disposed inside a nozzle group in which a plurality of nozzles that attract parts are disposed, and transmits incident light while diffusing the light; an image pickup unit that is disposed outside of the nozzle group apart from the diffusion member in a first direction, picks up an image of a part that is attracted by one nozzle, that is located on a virtual line extending in the first direction with respect to the diffusion member, from among the plurality of nozzles constituting the nozzle group, against a background of the diffusion member, and obtains an image of the part; wherein the nozzle group includes another nozzle that is located on a virtual line extending in a second direction, opposite from said first direction and is disposed opposite side of the one nozzle with respect to the diffusion member such that the diffusion member is located between said one nozzle and the another nozzle; an irradiation unit that is disposed outside of the nozzle group apart from the diffusion member in the second direction, and that radiates light toward the another nozzle of the nozzle group; and an inspection unit that inspects an attraction state of the part attracted by the one nozzle on the basis of the image of the part picked up by the image pickup unit.
