Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a device for inspecting a stack of corrugated boards that is capable of efficiently inspecting any stack of corrugated boards and performing highly accurate image processing by imparting sufficient contrast to the stacked end faces of the stack of corrugated boards whose image is to be input. SOLUTION: Light projecting means 18 and 19 are provided for projecting light to the stacked end faces 5a and 5b of the stack of corrugated boards 5 from the side perpendicular to the stacking direction of the stack of corrugated boards 5, with a predetermined angle to the direction in which the stack of corrugated boards 5 is conveyed along a conveying path 10. Image pickup means 20, 21, 22 and 23 are provided for picking up images of the stacked end faces 5a and 5b of the stack of corrugated boards 5 illuminated by the light projecting means 18 and 19.
