  • Patent number: 11010573
    Abstract: An optical information reader includes a reflective member that reflects illumination light emitted from an illuminant toward a reading surface, and an image former ensured to present an imaging target held over the reading surface within an imaging region of an imager. The imaging region includes a first imaging region defined between the image former and the reading surface, and a second imaging region defined between the reading surface and the reflective member so as to be continuous to the first imaging region when light is internally reflected on the reading surface inside the housing. The reflective member is arranged outside the first imaging region, while the illuminant, the imager and the image former are arranged outside the second imaging region. The illuminant emits illumination light toward a reflecting surface of the reflective member in the second imaging region.

  • Publication number: 20200047529
    Abstract: There is provided with a printing apparatus. A transfer member cyclically passes a formation area and a transfer area of an ink image. A print unit forms an ink image on the transfer member by discharging ink to the transfer member in the formation area. A conveyance drum conveys a print medium and to which an ink image is transferred from the transfer member in the transfer area. A cleaning unit cleans the conveyance drum at a cleaning position where the cleaning unit contacts the conveyance drum. A displacing unit separates the cleaning unit from the cleaning position when the print medium passes the cleaning position.

  • Patent number: 9703249
    Abstract: When fixing is not necessary in a printing apparatus including a fixing unit, a sheet to be conveyed is allowed to avoid the fixing unit. Specifically, a fixing unit-bypass path is provided on a conveying path corresponding to the fixing unit. Further, when a surface treatment material is not applied to a sheet from a surface treatment material applying head, that is, when fixing processing is not performed by the fixing unit, a sheet is conveyed along a fixing unit-bypass path. Since a sheet is conveyed along an bypass path when fixing processing is not performed as described above, it is possible to prevent a sheet from being affected by heat or the like while the sheet passes through the fixing unit.
