Abstract
An ink-jet printer includes a sheet feed-in mechanism 60 for feeding a paper sheet, a rotary drum 10 having a peripheral surface 11 of a size larger than the paper sheet to be fed by the sheet feed-in mechanism 60, for rotating at a constant speed, a sheet holding system 20 for holding the paper sheet on the peripheral surface of the rotary drum, a print head 200 for printing an image by repeatedly ejecting ink onto the paper sheet held on the peripheral surface of the rotary drum 10 while the rotary drum 10 performs a predetermined number of rotations, a sheet separator 140 for separating the paper sheet from the peripheral surface 11 of the rotary drum, a sheet feed-out mechanism 160 for feeding out the paper sheet separated by the sheet separator 140, a control unit 111 for controlling the sheet feed-in mechanism 60, the rotary drum 10, the sheet holding system 20, the print head 200, the sheet separator 140 and the sheet feed-out mechanism 160. In particular, the control unit 111 is constructed such that the sheet holding system 20, the print head 200 and the sheet separator 140 are sequentially driven on the basis of the number of rotations of the rotary drum 10.
