Abstract: A work-machine splash guard for enclosing a space for machining a workpiece, and preventing the spraying of chips and machining fluid, is equipped with: a front-surface door for opening and closing in the horizontal direction via an arc-shaped movement, and positioned on the front-surface side of the work machine; a side-surface door for opening and closing by performing an arc-shaped movement that is concentric with the front-surface door, and overlapping with the front-surface door; and door-locking switches for selectively allowing the opening/closing of the front-surface door and the side-surface door according to an opening/closing pattern.

Abstract: An ink-jet printer includes a rotary drum 10 for rotating at a constant speed, a sheet loader for loading a paper sheet onto the rotary drum 10, a sheet holding system 20 for holding the paper sheet loaded by the sheet loader on the rotary drum 10, and a print head 200 for printing an image by ejecting ink onto the paper sheet which is held on the rotary drum 10 by the sheet holding system 20 and rotated together with the rotary drum 10. In particular, the sheet loader has a pair of loading rollers 91 and 92 for feeding the paper sheet while pinching the paper sheet, and a roller moving mechanism 28 for separating the loading roller 91 from the other loading roller 92 to release the paper sheet after the leading edge of the paper sheet has been held on the rotary drum 10.

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.

Abstract: 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.
