  • Publication number: 20110221118
    Abstract: A sheet member transporting apparatus in which increase in number of components is restrained to reduce time and effort for assembly even when a curved route portion having a level difference in the direction of gravitational force is provided in a midsection of a transporting route, and a recording apparatus having the sheet member transporting apparatus are provided. A pivotable member configured to be capable of supporting a printing surface of a sheet fed by a sheet feed roller toward the downstream side pivots about a pivot shaft extending along the width direction of the sheet intersecting the direction of transport of the sheet so as to draw a curved trajectory having the level difference in the direction of gravitational force to receive the sheet pivoted together with the pivoting member and transport the sheet toward the downstream side in the direction of transport.

  • Patent number: 7036811
    Abstract: Systems and methods of registration system control are provided that compensate for differences in physical properties of various substrates being transported through the system that impact the displacement of the substrate through a given path. Exemplary systems of the invention include at least one roll pair formed by a first, driven roll and a second roll defining a nip therebetween that is part of the transport path through which a substrate is passed. A prestored lookup table includes empirically- or theoretically-derived compensation factors for plural different kinds of substrates, with each compensation factor being based on physical characteristics of the substrate that impact actual travel length of the substrate along the transport path, such as the substrate's mass per unit area, which has been found to have a strong correlation with a substrate's bending stiffness, which has been found to have a strong correlation with detected deviations in linear travel path.

  • Patent number: 6568674
    Abstract: A paper feeding apparatus including a feed roller supplying paper to a image reading position and a discharge roller discharging the paper. A load in the rotational direction is provided at the discharge roller to prevent the image reading turbulence at the time when the paper is separated from the feed roller.
