Abstract
A sheet conveying device includes: a tray; a roller; a roller arm; a lever; and a dust proof cover including: a first cover, a second cover, and a pressure piece. The roller arm is movable between an abutment position where the roller abuts on the tray and a separation position where the roller is away from the tray. The second cover is movable between a first position in proximity to the tray and a second position away from the tray. The pressure piece is away from the lever to permit the roller to be positioned in the abutment position when the second cover is in the first position, and presses the lever to move the roller to the separation position when the second cover is in the second position.
Claims6
A sheet conveying device comprising:
- a housing;
- a sheet supply tray supported to the housing and pivotally movable about a first pivot axis between a closed position in proximity to the housing and an open position away from the housing, the sheet supply tray having a sheet supporting surface on which a sheet to be conveyed is supported;
- a feed roller configured to feed the sheet supported on the sheet supply tray into the housing;
- a roller arm supporting the feed roller, the roller arm being supported to the housing and pivotally movable about a second pivot axis parallel to the first pivot axis between an abutment position where the feed roller is in abutment with the sheet supply tray and a separation position where the feed roller is positioned spaced apart from the sheet supply tray;
- a lever provided at the roller arm and pivotally movable about the second pivot axis together with the roller arm;
- and
- a dust proof cover configured to cover a portion of the sheet supporting surface, the dust proof cover comprising:
- a first cover supported to the housing and pivotally movable about a third pivot axis parallel to the first pivot axis;
- a second cover supported to the first cover and pivotally movable about a fourth pivot axis parallel to the third pivot axis between a first position in proximity to the sheet supply tray and a second position away from the sheet supply tray;
- and
- a pressure piece provided at the second cover and pivotally movable about the fourth pivot axis together with the second cover, the pressure piece being away from the lever to permit the feed roller to be positioned in the abutment position in a state where the second cover is in the first position, and the pressure piece pressing the lever to move the feed roller to the separation position in a state where the second cover is in the second position.

An image recording apparatus comprising:
- a sheet conveying device;
- and
- an image recording portion configured to record an image on the sheet conveyed by the sheet conveying device,
- the sheet conveying device comprising:
- a housing;
- a sheet supply tray supported to the housing and pivotally movable about a first pivot axis between a closed position in proximity to the housing and an open position away from the housing, the sheet supply tray having a sheet supporting surface on which a sheet to be conveyed is supported;
- a feed roller configured to feed the sheet supported on the sheet supply tray into the housing;
- a roller arm supporting the feed roller, the roller arm being supported to the housing and pivotally movable about a second pivot axis parallel to the first pivot axis between an abutment position where the feed roller is in abutment with the sheet supply tray and a separation position where the feed roller is positioned spaced apart from the sheet supply tray;
- a lever provided at the roller arm and pivotally movable about the second pivot axis together with the roller arm;
- and
- a dust proof cover configured to cover a portion of the sheet supporting surface, the dust proof cover comprising:
- a first cover supported to the housing and pivotally movable about a third pivot axis parallel to the first pivot axis;
- a second cover supported to the first cover and pivotally movable about a fourth pivot axis parallel to the third pivot axis between a first position in proximity to the sheet supply tray and a second position away from the sheet supply tray;
- and
- a pressure piece provided at the second cover and pivotally movable about the fourth pivot axis together with the second cover, the pressure piece being away from the lever to permit the feed roller to be positioned in the abutment position in a state where the second cover is in the first position, and the pressure piece pressing the lever to move the feed roller to the separation position in a state where the second cover is in the second position.
