20110102531 | PRINTING APPARATUS - A printing apparatus includes a printing medium support unit that supports and guides a printing medium supplied to a print execution area. The printing medium support unit includes a support portion supporting the printing medium defines a predetermined gap with a print head. A suction groove is formed concavely on a support surface of the support portion. A suction opening in the suction groove communicates with a suction source. A movable adsorption portion in the suction groove has a suction hole. Before the printing medium is supplied, the movable adsorption portion is located at an upper limit position higher than a support height of the support portion. When the printing medium is supplied, the suction hole is blocked by the printing medium, creating negative pressure, and thus the movable adsorption portion is moved to a lower limit position no higher than the support height of the support portion. | 05-05-2011 |
20130277482 | MEDIUM TRANSPORT APAPRATUS AND RECORDING APPARATUS - A recording medium after printing which is discharged from a main body of a printer is guided from the main body to a support surface of a discharge support portion extending to a lower anterior side, and is wound as a roll body by a winding unit in a path that passes a tension roller. A tape-shaped elastic member is fixed on an end portion of a downstream side in a transport direction of the discharge support portion so as to extend in a width direction. An elastic friction surface is formed on the end portion of the downstream side in the transport direction of the support surface. A friction coefficient between the elastic friction surface and the recording medium is higher than the friction coefficient between a portion at an upstream side in the transport direction from the elastic friction surface in the support surface and the recording medium. | 10-24-2013 |
20140125750 | PRINTING APPARATUS - A printing apparatus includes a transfer device that transfers a printing medium in a transfer direction, a platen having a support surface that supports the printing medium thereon, a liquid ejection head that ejects an ink onto the printing medium on the support surface, and a heating device that heats the printing medium. The transfer device includes a plurality of driven rollers. The support surface of the platen has a plurality of suction holes that suck the printing medium on the support surface. The support surface includes first portion extending in the transfer direction corresponding to extension lines extending in the transport direction from the portions between each driven roller, and second portions other than the first portions. The first portions are high-density regions where the suction holes are arranged at high density, and the second portions are low-density regions where the suction holes are arranged at low density. | 05-08-2014 |
20140197267 | MEDIUM TRANSPORT DEVICE - A medium transport device is provided. The medium transport device includes a transporting portion that transports a medium in a transport direction, a winding portion that winds the medium, and a friction member that suppresses displacement of the medium in a cross direction with the transport direction. The displacement in the cross direction is suppressed by causing the friction member to contact the medium. A contact state of the medium with the friction member is changed in accordance with a winding mode in which the medium transported by the transporting portion is wound around the winding portion, and a non-winding mode in which the medium transported by the transporting portion is not wound around the winding portion. | 07-17-2014 |
20140205959 | MEDIUM HEATING DEVICE - A medium heating device includes a heater that heats a medium, and a medium support member that supports a target heating portion, which is a portion that is heated by the heater in the medium, in which the medium support member has a first component portion that is formed so that a space is provided between the medium and the first component portion when the medium is supported, and a second component portion that is in contact with the medium when the medium is supported. | 07-24-2014 |
20140218423 | MEDIUM TRANSPORTATION DEVICE AND RECORDING APPARATUS - A medium transportation device includes a transportation section that transports a recording medium in a transport direction; a winding section that winds the recording medium transported by the transportation section; and a medium support section that is disposed between the transportation section and the winding section and has a medium support section supporting the recording medium. The medium support section has a support sliding section including a first surface and a second surface. A coefficient of friction of the first surface with the recording medium is greater than a coefficient of friction of the medium support surface with the recording medium and a coefficient of friction of the second surface with the recording medium is lower than the coefficient of friction of the first surface with the recording medium. | 08-07-2014 |
20140285601 | RECORDING APPARATUS - A recording apparatus that includes a condensation guide portion is provided. The recording apparatus includes a recording head that discharges ink onto a recording medium, a heater that dries the ink discharged on the recording medium by the recording head without making contact with the recording medium, a medium supporting portion provided with an opening portion which allows vapor that evaporates from the ink due to the heater to pass therethrough, and a condensation guide portion which causes the vapor that passes through the opening portion to condense and thereby prevent the recording medium from being wetted by the condensed vapor. | 09-25-2014 |
20140285602 | RECORDING APPARATUS - A recording apparatus includes a recording head which discharges ink onto a recording medium; a heater which dries the ink discharged on the recording medium by the recording head without making contact with the recording medium; and a transport belt which supports the recording medium in a transportable manner in a position in which it is at least possible to dry a portion of the recording medium on which the ink is discharged using the heater. The transport belt includes a plurality of protruding portions, which can make contact with the recording medium, and a contact area between a contact portion of the protruding portion in relation to the recording medium, and the recording medium is 0.3 mm | 09-25-2014 |
