  • Patent number: 9927758
    Abstract: In an image forming apparatus, a tray having first and second receiving portions is configured to move between a first position, at which at least part of the tray is positioned inside an apparatus body, and a second position, at which the tray is outside the apparatus body. The tray in the first position allows a first recording medium to be conveyed from the first receiving portion. When the tray is in the first position, the second receiving portion is configured to move between a third position, which is at an upstream side relative to a first opening of the apparatus body in a second direction, and a fourth position, which is at a downstream side relative to the third position in the second direction. The second receiving portion at the third position allows a second recording medium to be conveyed from the second receiving portion in the second direction.

  • Patent number: 8585037
    Abstract: In a media tray, a mid-tray sensor is located relatively equally distant between the tray front and the tray back. This allows the tray to be free of a divider between the front and reserve stack areas. After the user closes the tandem tray, an elevator plate lifts media in the lead stack location and a slider moves in a forward direction toward the tray front based on the front media sensor not detecting media in the front stack area, or whenever the mid-tray sensor detects media located between the front stack area and the reserve stack area. An alarm is produced when the front media sensor does not detect any media, or when the slider is unable to move when it should be able to move (forward into the front stack area, back through the reserve stack area, etc.).

  • Patent number: 7963517
    Abstract: A sheet feed device includes a first sheet cassette having an accommodating portion accommodating a first plurality of sheets and a second sheet cassette, disposed on the first sheet cassette, accommodating a second plurality of sheets. The sheet feed device also includes a sheet feeder configured to selectively feed the first plurality of sheets and the second plurality of sheets toward a sheet feed path, and a sheet separator configured to separate, one by one, the sheets fed by the sheet feeder. Specifically, the second sheet cassette is configured to move above the accommodating portion and with respect to the sheet feeder between a sheet feed position in which the sheet feeder contacts sheets accommodated in the second sheet feed cassette to a non-sheet feed position in which the second sheet feed cassette prevents the sheet feeder from contacting sheets accommodated in the second sheet feed cassette.
