Abstract
A sheet feeder includes a first tray and a second tray. The first tray is movable to a first open position and a second open position. The second tray is movable between a closed position and an open position. When the second tray is in the closed position and the first tray is in the first open position, a first tray surface of the first tray forms a first angle with the chute surface. When the second tray is in the open position and the first tray is in the second open position, the first tray surface is located between the chute surface and a second tray surface of the second tray and forms a second angle with the chute surface, the second angle being smaller than the first angle and the first and second angles are obtuse angles.
Claims16
A sheet feeder comprising:
- a chute comprising a sheet feeding unit protruding from a chute surface;
- a first tray having a first tray surface and movable to a first open position and a second open position;
- and
- a second tray having a second tray surface and movable between a closed position and an open position,
- wherein, when the second tray is in the closed position and the first tray is in the first open position, the first tray surface forms a first angle with the chute surface, and
- wherein, when the second tray is in the open position and the first tray is in the second open position, the first tray surface is located between the chute surface and the second tray surface, and forms a second angle with the chute surface, the second angle being smaller than the first angle, and the first and second angles are obtuse angles.
A sheet feeder comprising:
- a housing having a chute surface;
- a feed roller having a surface protruding from the chute surface;
- a first tray rotatably connected to the housing, the first tray being rotatable between a first closed position and a first open position around a first rotation axis, the first rotation axis being parallel to an axis of the feed roller, the first tray being located closer to the housing in the first closed position than when the first tray is located in the first open position, and the first tray being biased toward the housing and being engaged with the housing when the first tray is in the first open position;
- and
- a second tray rotatably connected to the housing, the second tray being rotatable between a closed position and an open position around a second rotation axis, the second rotation axis being parallel to the axis of the feed roller and different from the first rotation axis, the second tray being located closer to the housing in the closed position than when the second tray is in the open position, and the second tray being in contact with the first tray and causing the first tray to be located in a second open position between the first open position and the first closed position when the second tray is in the open position,
- wherein a first length from a first end to a second end of a first tray surface in a sheet conveyance direction along the first tray surface, second tray surface and chute surface is smaller than a second length from a first end to a second end of the second tray surface in the sheet conveyance direction.
