PROBLEM TO BE SOLVED: To surely photograph a print worked on a sheet and a punching-out shape, in a state of being free from slant. SOLUTION: A plurality of lines of suction conveyers 21 which suck and carry corrugated board sheets S sent from supply conveyers 11 down to position passing downward of a camera 2 are installed on discharge end sides of a plurality of lines of the supply conveyers 11. A positioning conveyer is installed between rows of the supply conveyers 11 and the suction conveyers 21. Positioning protrusions 35 are installed on the carrying surface of a positioning conveyer 31. A sheet carrying speed of the supply conveyers 11 is made higher than that of the positioning conveyer 31. The tip end edges of the corrugated board sheets S sent in the supply ends of both of the conveyers 11, 31 are made to abut against the positioning protrusions 35 by using the difference of speeds of both of the conveyers 11, 31. The corrugated board sheets S are sent onto the suction conveyers 21 in a state of constant direction, and sucked and carried down to the position passing downward of the camera 2 with the suction conveyers 21.
