Abstract: 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.

Abstract: 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.

Abstract: 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.
