| 20090033731 | INKJET PRINTER - In an inkjet printer in which upstream and downstream output rollers engageable against their respective counter parts are disposed upstream and downstream, respectively, of a drying unit for drying printing paper after being printed, the upstream output roller is disengaged from its counter part after the disengagement between the downstream output roller and its counter part. | 02-05-2009 |
| 20090189337 | PAPER OUTPUT MECHANISM - A paper output mechanism includes: a roller pair composed of a first roller and a second roller travelable around the first roller and configured, when the second roller is in a first position, to output a piece of paper to a paper placement part by pinching the piece of paper between the first and second rollers and driving at least one of the first and second rollers into rotation with an actuator; and a roller position changing mechanism for switching the second roller between the first position and a second position located closer to the paper output side than the first position. When the trailing edge of the piece of paper is sent out to the paper placement part, the roller position changing mechanism changes the second roller from the first position to the second position. | 07-30-2009 |
| 20090190982 | PRINTING SYSTEM - In a printing system, a position changing element moves a decurling roller around a conveyance roller to switch the position of the decurling roller relative to the conveyance roller at least between a decurling position in which a paper web is conveyed while being decurled and a conveyance position in which paper is conveyed without being decurled, and positions the decurling roller in the conveyance position when the conveyance of the paper is stopped. | 07-30-2009 |
| 20090190983 | DECURLING MECHANISM - A decurling mechanism moves a decurling roller around a conveyance roller by means of a position changing roller to change the relative position of the decurling roller to the conveyance roller to a decurling position in which a piece of paper web is conveyed while being decurled and a conveyance position in which a paper sheet is conveyed without being decurled. In this case, the clearance between the decurling roller and the conveyance roller when the decurling roller is in the decurling position is set to be larger than that when the decurling roller is in the conveyance position. | 07-30-2009 |
| 20090190984 | DECURLING MECHANISM - A decurling mechanism is configured so that a position changing roller moves a decurling roller among a plurality of decurling positions from the weakest decurling position to the strong decurling position. In this manner, the decurling force applied to each piece of paper web is set large when the piece of paper web has a length not smaller than a predetermined value, but set small when the piece of paper web has a length smaller than the predetermined value. | 07-30-2009 |
| 20090190985 | DECURLING MECHANISM - A decurling mechanism for performing a decurling process of correcting the curl of paper includes: a first roller; a second roller disposed travelably around the first roller; and a roller position changing mechanism for changing the second roller to a plurality of positions set on a traveling path of the second roller. The plurality of positions include a decurling position in which the decurling process to the paper is enabled and the paper is conveyed while being pinched between the first and second rollers, a conveyance position in which the decurling process to the paper is disabled and the paper is conveyed while being pinched between the first and second rollers and a pinch release position in which the paper is released from the pinch between the first and second rollers. | 07-30-2009 |
| 20090245913 | IMAGE FORMING APPARATUS - Printing paper is cut by moving the lower one of a pair of upper and lower cutting blades with the upper one fixed. A protective member for preventing the printed surface of the printing paper being conveyed from coming into contact with the cutting edge of the upper cutting blade is disposed upstream of the upper cutting blade in the direction of paper conveyance. | 10-01-2009 |
| 20100073449 | INKJET PRINTER - In a consecutive processing in which an inkjet printer A consecutively performs printing on a plurality of media sheets and cutting the front ends and the rear ends of the media sheets, a feed interval between any two consecutive media sheets in a cutting section is set larger than that in a printing section. | 03-25-2010 |
