Abstract:
1. A sheet feeding apparatus comprising: a pressure plate for supporting a sheet and movable between a contact position for contacting a sheet feeding roller and a position separated from the contact position; a positioning portion that is disposed in the pressure plate and that contacts against a side end of the sheet to limit the position of the side end of the sheet; a sheet feeding frame for movably supporting said pressure plate; a sheet feeding tray for supporting the sheet, wherein the sheet feeding tray is openably and closably provided in an apparatus body, the sheet feeding tray supports the sheet when said sheet feeding tray is opened, and the sheet feeding tray faces the pressure plate when said sheet feeding tray is closed; a limiting member that is disposed in the sheet feeding tray and that limits a position of the side end of the sheet wherein the pressure plate supports a part of the sheet and the sheet feeding tray supports another part of the sheet; first position limiting means for limiting the position in the sheet width direction of the sheet feeding tray with respect to an external cover when the sheet feeding tray is in a closed state; and second position limiting means for limiting the position in the sheet width direction of the sheet feeding tray with respect to the sheet feeding frame when the sheet feeding tray is in an open state, wherein the first position limiting means does not limit the position of the sheet feeding tray when the sheet feeding tray is opened, wherein the limiting member contacts the sheet with a same side end as the positioning portion contacts, wherein the limiting member contacts a portion of the side end of the sheet upstream from a portion of the side end of the sheet contacted by the positioning portion, and wherein the limiting member rises with respect to the sheet feeding tray in response to an operation to open the sheet feeding tray, and the limiting member collapses in response to an operation to close the sheet feeding tray.
