  • Publication number: 20140139606
    Abstract: To perform preheating on a recording medium before transfer with an inexpensive configuration to reduce a transfer failure due to a change in temperature of a transfer film and further reduce thermal damage to the transfer film, in a transfer apparatus for nipping a transfer film and recording medium with a transfer roller and transfer platen, preheating treatment of the recording medium is performed by heat of the transfer roller before transfer processing. When the preheating treatment is performed using the transfer roller, the transfer film exists between the transport roller and the recording medium, and by shifting the position of the transfer film during the preheating treatment, it is possible to suppress thermal damage to the transfer film without applying heat of the transfer roller to only a part of the transfer film excessively.

  • Patent number: 8363076
    Abstract: A printing apparatus 1 compares a distance ? from a printing finish position of received printing data to a card rear end with a distance ? set corresponding to a peeling distance ? in which an ink ribbon R peels off from a card C, and thereby determines whether or not the printing finish position is within the distance ? from the card rear end. As a result, when it is determined that the printing finish position is within the distance ? from the card rear end, it is controlled that reeling of the ink ribbon R is performed by at least a distance obtained by adding the distance ? to the distance ? after printing on the card C is finished, and that the thermal head is then retreated to a retreat position. By this means, when the printing finish position is in the vicinity of the card rear end, the sag of the ink ribbon pulled out by a drop of the thermal head is resolved, and the ink ribbon does not wind itself around the platen roller.
