Patent number: 9771228Abstract: A sheet feeding device has a mounting portion allowing a stack of sheets to be mounted in a top-bottom direction, a suction/transportation portion provided above the mounting portion for attracting a first sheet positioned on top of the stack, and a blowing portion for blowing air to a foremost edge of the first sheet in a transportation direction while the first sheet is being attracted by the suction/transportation portion, thereby separating the first sheet from a second sheet next to the first sheet. After the first sheet is separated from the second sheet, the suction/transportation portion transports the first sheet in the transportation direction. The suction/transportation portion sets a suction force applied to the foremost edge of the first sheet smaller when the blowing portion blows air to the first sheet than when the suction/transportation portion transports the first sheet.Type: GrantFiled: July 15, 2014Date of Patent: September 26, 2017Assignee: KONICA MINOLTA, INC.Inventors: Hiroshi Mizuno, Atsuhiko Shimoyama, Noboru Oomoto, Hiroaki Umemoto, Ryo Oshima
