To prevent a sheet with low rigidity from fluttering while suppressing the floating of the sheet from an outer peripheral surface of an impression cylinder on free end side of the sheet.
When a rubber cylinder 16E is in a cylinder drawn state, while a part from a front end to the middle of the sheet S passes a photographing area 30A, a first sheet pressing device 31 on the upstream side is operated to press the sheet S to the outer peripheral surface of the impression cylinder 17E, and a second sheet pressing device 32 on the downstream side stops the operation. While a part from the middle to a rear end of the sheet S passes the photographing area 30A, the second sheet pressing device 32 is operated to press the sheet S to the outer peripheral surface of the impression cylinder 17E, and the first sheet pressing device 31 stops the operation.
