Abstract
The sheet feeding apparatus includes a feeding roller that includes an arc-shaped friction portion and a notch portion, and causes the friction portion to feed the sheet; a feeding motor rotationally driving the feeding roller; a separation pad that presses the sheet fed by the friction portion on a surface other than a surface at the friction portion, and separates a double-fed sheet; and a feeding spring that causes the sheet supporting portion to wait below the feeding roller such that the sheet supported on the sheet supporting portion is not in contact with the friction portion until the friction portion reaches the separation pad, and, when the friction portion reaches the separation pad, moves up the sheet supporting portion to an abutting position at which the sheet supported on the sheet supporting portion is pressed against the friction portion and the friction portion feeds the sheet.
