Abstract

An image inspection device has a first suction conveyance unit which is arranged on the upstream side with a conveyance surface as an upper surface, a second suction conveyance unit which is arranged on the downstream side with a conveyance surface as a lower surface to make the conveyance surface continuous from the upstream side, a first inspection section which inspects an image on a front surface of an inspection object which is conveyed to the first suction conveyance unit and a second inspection section which inspects an image on a back surface of the inspection object which is conveyed to the second suction conveyance unit. The inspection object is conveyed in a state of being sucked and held on the first and second suction conveyance units and therefore is stable in position and posture in conveyance and an expected accuracy is maintained in inspection performed by the first and second inspection sections.
