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.

摘要： An ink-jet printer includes a rotary drum which rotates at a constant speed; a medium holding system which holds a printing medium on the rotary drum; and a print head which prints an image by jetting ink onto a printing medium which is held on the rotary drum by the medium holding system and which rotates along with the rotary drum, while the rotary drum makes a predetermined number (greater than one) of rotations during a printing operation. The medium holding system includes a front-end clamping section, on the peripheral surface of the rotary drum, for clamping a front end of the printing medium; a rear-end clamping section set apart from the front-end clamping section in a rotational direction of the rotary drum along the peripheral surface of the rotary drum, for clamping a rear end of the printing medium; and a driving section for driving the front-end clamping section and the rear-end clamping section to clamp the printing medium on the peripheral surface of the rotary drum during one rotation of the rotary drum made before printing of the image is initiated and to release the printing medium from the peripheral surface of the rotary drum during another rotation of the rotary drum made after printing of the image is completed. A motion of the rear-end clamping section is mechanically enabled by a motion of the front-end clamping section after the rotary drum rotates by an amount which corresponds to a distance between the front-end and rear-end clamping sections.
