  • Patent number: 8157256
    Abstract: A sheet handling apparatus is provided that includes a take-out member to take out a sheet from a take-out position by rotating the sheet in a state in which negative pressure is applied to the sheet and the sheet is adsorbed to the take-out member. A conveyor portion receives and conveys the taken out sheet by the take-out member and a control portion controls the take-out member such that, when the sheet at the take-out position is being adsorbed to the take-out member, the take-out member is rotated at a circumferential speed that is slower than a conveying speed of the sheet at the conveyor portion. In addition, when the sheet adsorbed to the take-out member is being transferred to the conveyor portion, the take-out member is rotated at a circumferential speed that is the same as a conveying speed of the conveyor portion at that time.
