摘要： An ink-jet printer includes a rotary drum 10, having a dielectric peripheral surface 11, for rotating at a constant speed, a sheet loader 90 for loading a sheet to the rotary drum 10, a sheet holding system for causing the sheet to be held on the peripheral surface 11 of the rotary drum 10, and a print head section 200 for printing an image on the sheet held on the peripheral surface 11 of the rotary drum 10 by jetting ink to the sheet while the rotary drum 10 makes a predetermined number of rotations. Particularly, the sheet holding system includes a charging section 20 and a supplementary charger section 26. The charging section 20 charges the peripheral surface 11 of the rotary drum 10 on an upstream side of the loading point where the leading end of the sheet loaded by the sheet loader 90 contacts the peripheral surface 11 of the rotary drum 10. The supplementary charger section 26 charges the sheet to supplement the electrostatic attraction force attenuated during the rotation of the rotary drum 10.

摘要： An ink-jet printer includes a rotary drum for rotating at a constant speed and holding a paper sheet on its peripheral surface, a print head having ink-jet nozzles aligned in the axial direction of the rotary drum to perform printing by spitting ink from these ink-jet nozzles on the paper sheet rotating together with the rotary drum, and a sheet feed-in mechanism for feeding a paper sheet from a cassette and a manual feed tray to the rotary drum. Particularly, the sheet feed-in mechanism has a loading roller unit for loading the paper sheet to the rotary drum, a pickup section for picking up a paper sheet from one of the cassette and the manual feed tray to strike the leading end of the paper sheet against the loading roller unit, and a control section for controlling the loading roller unit to feed, to the rotary drum, the paper sheet whose posture has been corrected upon strike by the pickup section. The pickup section has a paper feed path which guides the paper sheet picked up from one of the cassette and the manual feed tray to the loading roller unit via a merging point, and has a bend accepting space located at the merging point for accepting a bend of the paper sheet.

摘要： An apparatus for holding a printing medium on a rotary drum, includes a rotary drum, a suction device, a medium holding mechanism and a medium removing device. The drum has a recess at its outer surface to extend along its rotation center line and rotates at a predetermined speed. A region of the outer surface, which is adjacent to a rearward end of the recess along the rotation direction, is smaller in the diameter than the remaining of the outer surface. The suction device holds by suction the medium onto the outer surface. The holding mechanism has a hook in the recess and selectively drives the hook between close and open positions. At the close position, the hook is placed over the adjacent region while being prevented from radially outwardly projecting from the remaining of the outer surface, and at the open position it is distanced from the adjacent region. When the medium arrives at the adjacent region, its leading end is held by the hook shifted from the open position to the close position and cooperated with the adjacent region and, when the drum rotates a specific number, the hook is returned to the open position. The removing device removes the medium from the outer surface when the drum rotates the specific number and the hook has moved from the close position to the open position.

摘要： Suction ports (14) are provided in one end (15R) of a drum (10), connecting the interior (16) and exterior of the drum (10). Corresponding suction ports (34) are provided at a stationary side (5R), opposing the suction ports (14), respectively. A suction fan (32) is provided, which draws air from the interior (16) of the rotating drum (10) through the corresponding suction ports (34) and the suction ports (14). A printing medium M can be attracted and held onto the outer circumferential surface (11) of the drum (10) by virtue of negative pressure, by utilizing the negative pressure generated in the interior (16) of the drum (10) as the suction fan (32) rotates and a plurality of suction holes (12) extending in a radial direction and connecting the interior and exterior of the drum (10). A damper (38) is provided at the air outlet port of the suction fan (32), for opening and closing the outlet port of the fan (32).
