  • Patent number: 9346648
    Abstract: A sheet processing device conveys a paper sheet onto which an adhesive is applied, and includes a bonding member that applies adhesives onto the conveyed paper sheet at intervals in a sheet width direction; and a protruding guide that is positioned on a conveying path, downstream of the bonding member in a sheet conveying direction, and guides the paper sheet, facing an adhesive-applied surface of the paper sheet. The protruding guide is positioned between sheet width direction lines of the adhesive-applied position and includes a protruding portion protruding into the conveying path. With this configuration, it is possible to suppress the adhesive from being adhered to a device component even in a configuration in which an adhesive-applied paper sheet is moved inside the device to make a sheet jam due to the adhesion less likely to occur.

  • Patent number: 8963974
    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: 8810619
    Abstract: Provided is a printer capable of ensuring a large peeling angle at the time of peeling between the transfer film and the ink ribbon by differentiating a conveyance direction of the transfer film at a peeling part on a proceeding passage from the proceeding direction. In the printer which forms an image on a transfer film 46 while feeding an ink ribbon 41 and the transfer film 46 to a print position between a platen roller 45 and a thermal head 40 which are mutually pressure-contacted, the transfer film 46 is wound to form a conveyance passage between a feeding spool 48 and a winding spool 47 in a film cassette 100 which is attached to a device frame in a detachably attachable manner, and a film conveying roller 49 and pinch rollers 32a, 32b are arranged at positions so that the conveyance passage of the transfer film 46 attached to the device frame is displaced to the inside of the cassette by a predetermined amount.
