<p>PROBLEM TO BE SOLVED: To convey a sheet correctly even when a sheet supply form is intermittent supply.SOLUTION: A sheet supply device 10 includes a sheet conveyance part 40 which has suction means 80a, 80b, 81a and 81b for adsorbing a sheet 1 to a conveyor belt 70, and which conveys so that a conveyance direction downstream side of a following sheet 1 comes between a conveyance direction upstream side of a preceding sheet 1 and the conveyor belt 70. The sheet supply device 10 includes: sheet supply parts 20 and 30 which can supply the sheet 1 to the sheet conveyance part 40 in a continuous supply manner and in an intermittent supply manner; and suction switching means 90 which can switch a contact range C between the sheet 1 which is positioned at a register adjustment position during intermittent supply and the conveyor belt 70 in such a manner that, during the intermittent supply,it is in a state where suction of the sheet 1 by the suction means 80b and 81b is not performed, and during the continuous supply, it is in a state where suction of the sheet 1 by the suction means 80b and 81b is performed.</p> |
