  • Patent number: 9162485
    Abstract: A treatment liquid application device for use in an inkjet printer includes an application roller to apply a treatment liquid to a recording medium before an image is formed on the recording medium, a squeeze roller disposed below the application roller and to make a pressure-contact with the application roller, a treatment liquid supply unit to supply the treatment liquid to a nip part between the application roller and the squeeze roller, and a pressure roller disposed above the application roller and to cause the recording medium to make a pressure-contact with the application roller. When the application roller applies the treatment liquid to the recording medium, a position of the application roller is not restricted in approximate load directions of the squeeze roller and the pressure roller but is restricted in directions other than the approximate load directions.

  • Patent number: 7327664
    Abstract: An optical fiber array is constructed by using a plurality of laser modules, which guide a laser beam emitted from a semiconductor laser of a blue color wavelength to an optical fiber, such that beam emitting ends of respective optical fibers are aligned in one row at an equal interval, and the laser beam being output from the optical fiber array is used as a multibeam of an optical recording apparatus. A relative refractive index difference of the used optical fiber is set between 0.1% to 0.2%, and a core diameter is set to 4.5 ?m or less, and also a mode field diameter of the optical fiber, i.e., a diameter of a beam spot emitted from the optical fiber is set to 3 ?m or more.
