The unit body is displaceable between a first position at which the driven transmission unit is connected to the drive transmission unit and a second position at which the driven transmission unit is separated from the drive transmission unit. When a user pulls out the medium, the unit body retained at the first position moves from the first position to the second position.

  • Patent number: 8955844
    Abstract: An image reading apparatus having a sheet path, which includes two ejection paths, is provided. The sheet path is switchable between the two ejection paths by a switchable member. An outlet cover arranged on a casing of the image reading apparatus is movable between a closed position and an open position to open and close an outlet of the second ejection path. When the outlet cover moves from the closed position to the open position, and before the switchable member switches the sheet path from the first ejection path to the second ejection path, switching of the sheet path from the first ejection path to the second ejection path is detectable.

  • Patent number: 8944431
    Abstract: A media inverting system is described for a cut sheet printing system. A first media transport advances a media sheet in a first direction, the media sheet having a first side that contacts the first media transport and an opposing second side. A rotatable member having a rotation axis that is substantially parallel to the first direction receives the media sheet from the first media transport and rotates to advance the media sheet around the rotatable member. A rotatable member force mechanism is switchable between a first state where the second side of the media sheet is held to the rotatable member, and a second state where the media sheet is released. A second media transport receives the media sheet from the rotatable member and advances the media sheet in an inverted orientation in a second direction that is substantially parallel to the first direction.
