Abstract: A sheet feeding device having; a mounting portion capable of accommodating a stack of sheets; a blowing device that blows air onto the stack placed in the mounting portion, thereby floating at least a top sheet from the stack; a suction/transportation mechanism that includes a suction belt provided above the mounting portion and attracting the top sheet floated by the blowing device to transport the attracted sheet toward a transportation path; an image pickup device disposed so as to capture an image of the floated top sheet and the next sheet therebelow; and an illuminating device that emits light toward an area to be captured by the image pickup device. The light emitted by the illuminating device illuminates a plane in a direction approximately normal thereto, the plane including the closest end surface of the stack of sheets to the image pickup device.

Abstract: A sheet supply apparatus includes: a tray on which a stack of sheets can be placed, an air blowing section that blows air towards the stack of sheets to float at least a topmost sheet, a sucking and conveying section, above the tray, that sucks said floating sheet(s) and conveys said sheet(s) in a prescribed direction, and a first light source that emits a first stripshaped slit light having a vertically extending component such that the slit light crosses at least a first edge of a first floating sheet and a second edge of a second floating sheet. An image capture section captures an image of the first slit light, a calculating section calculates a vertical clearance between the first and second sheets, and an air amount adjusting section adjusts an amount of air to be blown by the air blowing section based on the calculated vertical clearance.
