Sheet feeding apparatus and an image forming apparatus

A sheet feeding apparatus, comprising;

• a tray unit configured to be capable of taking a closed position at which the tray unit is closed with respect to an apparatus main body and an opened position at which the tray unit is opened with respect to the apparatus main body, the tray unit including a sheet stacking tray on which a sheet is stacked and tray arms disposed on both sides of the sheet stacking tray;
• a pickup roller configured to feed the sheet stacked on the sheet stacking tray;
• a roller holder rotatably provided on the apparatus main body, the roller holder being configured to support the pickup roller such that the pickup roller is capable of moving to a feeding position for feeding the sheet stacked on the sheet stacking tray and to a storage position at which the pickup roller is stored in the apparatus main body;
• and
• a pressure spring configured to urge the roller holder for urging the pickup roller toward the feeding position,
• wherein an abutting portion is provided on at least one end portion in a longitudinal direction of the roller holder, the abutting portion being configured to abut against the tray arms for moving the roller holder and for moving the pickup roller to the storage position when the tray unit moves from the opened position to the closed position.

An image forming apparatus which forms an image on a sheet fed by a sheet feeding apparatus, the sheet feeding apparatus comprising:

• a tray unit configured to be capable of taking a closed position at which the tray unit is closed with respect to an apparatus main body and an opened position at which the tray unit is opened with respect to the apparatus main body, the tray unit having a sheet stacking surface on which a sheet is stacked at the opened position;
• a feeding member configured to feed the sheet stacked on the tray unit;
• a feed supporting portion configured to support the feeding member such that the feeding member is capable of moving to a feeding position for feeding the sheet stacked on the sheet stacking surface and to a storage position at which the feeding member is stored in the apparatus main body;
• and
• an urging portion configured to urge the feeding member toward the feeding position,
• wherein the feed supporting portion includes an abutting portion configured to abut against a region other than the sheet stacking surface of the tray unit for moving the feed supporting portion and for moving the feeding member to the storage position when the tray unit moves from the opened position to the closed position.

An image forming apparatus which forms an image on a sheet fed by a sheet feeding apparatus, the sheet feeding apparatus comprising:

• a tray unit configured to be capable of taking a closed position at which the tray unit is closed with respect to an apparatus main body and an opened position at which the tray unit is opened with respect to the apparatus main body, the tray unit including a sheet stacking tray on which a sheet is stacked and tray arms disposed on both sides of the sheet stacking tray;
• a pickup roller configured to feed the sheet stacked on the sheet stacking tray;
• a roller holder rotatably provided on the apparatus main body, the roller holder being configured to support the pickup roller such that the pickup roller is capable of moving to a feeding position for feeding the sheet stacked on the sheet stacking tray and to a storage position at which the pickup roller is stored in the apparatus main body;
• and
• a pressure spring configured to urge the roller holder for urging the pickup roller toward the feeding position,
• wherein an abutting portion is provided on at least one end portion in a longitudinal direction of the roller holder, the abutting portion being configured to abut against the tray arms for moving the roller holder and for moving the pickup roller to the storage position when the tray unit moves from the opened position to the closed position.
