Abstract:
1. A sheet feeding apparatus comprising: a loading platen on which sheets are loaded; a first air blowing section which blows air to a lateral surface of a loaded sheet bundle loaded on the loading platen to float up a sheet; a second air blowing section which blows air to a leading edge of the loaded sheet bundle to separate the sheet; an adsorption/conveyance mechanism which adsorbs and conveys a top most sheet floated by air flow blown by the first air blowing section and separated by the air blow from the second air blowing section; and a driving section moving the loading platen up and down, wherein the first air blowing section includes an air blowing opening facing the lateral surface of the loaded sheet bundle and blowing air to the lateral surface from a perpendicular side to a conveying direction, wherein the air blowing opening is formed so that a first air flow flows above the loading platen and a second air flow flows below the loading platen when the loading platen reaches a highest position by the driving section, and wherein the loading platen is provided with a penetration through which the second air flow flows from below to above the loading platen to float up a sheet.
