Imaging device, surface inspection device equipped with imaging device, and molding machine

Abstract

To provide an imaging device that can properly image long objects 10 even if their lower surface has various shapes, including inclined surfaces. [Solution] According to the imaging device 40, a first head support part 42a and a second head support part 42b are arranged with a gap between them that allows the legs of the long object 10 to pass through, supporting the right and left bottom surfaces of the head. The imaging unit 48 captures images of the area including the position between the first head support part 42a and the second head support part 42b when the light source part 46 irradiates light into it, thereby acquiring imaging information. This provides an imaging device that can appropriately capture images even if the bottom surface of the long object 10 has various shapes, including inclined surfaces.

Claims
