Printing apparatus

摘要

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.

主权项

1. A printing apparatus comprising:
a transfer device including a plurality of rollers and configured to transfer a flexible printing medium in a transfer direction, the rollers being arranged in a direction intersecting the transfer direction; a platen disposed immediately downstream of the transfer device in the transfer direction, the platen including a plate having a support surface that supports thereon the printing medium transferred by the transfer device and includes first portions extending in the transfer direction corresponding to extension lines extending in the transfer direction from the portions between each of the rollers and second portions other than the first portions, the second portions corresponding to a width of the rollers, the platen having a plurality of suction holes that are open at the support surface so as to suck the printing medium on the support surface, the suction holes being arranged such that the first portions have suction holes with a higher density than the second portions; a head unit including a liquid ejection head that prints on the printing medium by ejecting an ink onto the printing medium on the support surface; and a heating device that heats the printing medium on which the ink has been ejected.
