  • Patent number: 8186797
    Abstract: An inkjet printer includes a platen having a placing face, a printing device, and a printing medium feeding device. A guide is provided on a feeding-out side via which a printing medium is to be fed out from the platen. The guide has a guide face. A printing medium temperature raising device is to heat the guide face so as to raise a temperature of the printing medium placed on the guide face. A temperature raising preventing device is provided between the guide face of the guide and a portion of the placing face facing a printing target region. The temperature raising preventing device is configured to prevent an extended portion of the printing medium from being heated by the printing medium temperature raising device. The extended portion corresponds an area which is extended to the feeding-out side by a predetermined length from the printing target region.

  • Publication number: 20110285801
    Abstract: An inkjet printer (P) is provided with a platen (20) which supports a printing medium, a printing means comprised of a carriage (40), an inkjet head (60) and the like for performing printing on the printing medium (M) that is supported by the platen (20), a medium feeding device (3) which supports a feeding shaft around which the printing medium (M) in an elongated sheet shape is wound and in which the feeding shaft is rotated to feed out the printing medium (M) toward the platen (20), and a medium winding device (4) which has the same shape as the medium feeding device (3) and supports a winding shaft for winding the printing medium (M) and in which the winding shaft is rotated for winding the printing medium (M) that has been fed out by the medium feeding device (3) and has been printed by the printing means.
