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 ink jet printer includes a rotary drum having a peripheral surface for holding a paper sheet, a print head for printing an image on the paper sheet held on the peripheral surface by jetting ink to the paper sheet, and an elevator mechanism for setting the print head to a printing position close to the peripheral surfice at a time of printing and to a non-printing position farther from the peripheral surface than the printing position along a normal line of the peripheral surface at a time of maintenance. Particularly, the elevator mechanism includes a pair of guide rails set parallel to the normal line of the peripheral surface, a slider unit rotatably holding the print head and slidably attached to the guide rails, and a driving section for moving the slider unit up and down. The slider unit includes a spindle, a head support member rotatable about the spindle by a rotational force applied due to a weight of the printhead, and a posture regulator for regulating a posture of the print head with respect to the guide rails against the rotational force.

摘要： A daisy wheel type printing device comprises a daisy printing wheel including a plurality of type holding members having type at the respective ends thereof, wheel driving motor for rotating the daisy printing wheel to set the type designated by input character data to a printing position, a printing hammer for hitting the type set to the printing position, and a control circuit for driving the printing hammer when a preset a period of time has elapsed after the type designated by the input character data has arrived at the printing position. The preset period of time is varied in response to the rotation amount by which said daisy printing wheel is rotated to set the designated type at the printing position. The delay is larger for a wheel rotation of less than a predetermined amount than it is for a large rotation.
