  • Patent number: 7583926
    Abstract: An image recording apparatus includes first to fifth transport paths. The first path transports a sheet from a sheet feeding section to a sheet output section through a first confluence, an image recording section, a first bifurcation, and a second confluence in that order. The second path transports a sheet from the first bifurcation down to a switchback section through a second bifurcation and a third bifurcation in that order. The third path transports a sheet from the third bifurcation to the first confluence through a third confluence, and vice versa. The third path is positioned between the switchback section and a portion of the first transport path located in the image recording section. The fourth path transports a sheet from the second bifurcation to the third confluence, and vice versa. The fifth path transports a sheet from the second bifurcation to the second confluence.

  • Patent number: 7398970
    Abstract: In the context of a structure wherein outer casing(s) is/are disposed so as to permit opening and closing about shaft(s), stopper member(s) and engagement piece(s) engaging with such stopper member(s) being disposed at such outer casing(s) so as to permit independent displacement in pivoting fashion about shaft(s) for each thereof, one end(s) of arm member(s) is/are supported by outer casing(s) so as to permit displacement in pivoting fashion, and shaft(s) of stopper member(s) is/are secured to other end(s) of such arm member(s). In addition, when bottom region(s) of stopper member(s) in engaged state(s) with engagement piece(s) abuts or abut and is/are pressed upward by original(s) loaded in original tray(s) during closing of outer casing(s) which had at least immediately prior thereto been in open state(s), this causes other end(s) of arm member(s) to be displaced upward in pivoting fashion, in accompaniment to which stopper member(s) is/are lifted upward.

  • Publication number: 20060071413
    Abstract: A sheet stacking device includes: an evacuation section for transporting and ejecting sheets; a sheet exit tray for stacking the ejected sheets; an arm supporting member; and a sheet presser arm including a supported end at one end, a free end at the other end which is capable of pressing the sheets stacked on the sheet exit tray directly or via a contact member attached to the free end, and a flexure portion having flexibility between the supported end and the free end. The supported end is attached to the arm supporting member. The arm can apply, by the flexibility of the flexure portion, a pressing force to the sheets stacked on the sheet exit tray and a repulsive force to each of the ejected sheets when a front end of the ejected sheet strikes against the arm.
