After forming a loop, a feeding means applies a force in the conveying direction to the bottom sheet, and after receiving a force in the opposite direction to the conveying direction by the feeding means, the bottom sheet receives a force in the conveying direction. In a sheet feeding device having a separation means for separating stacked sheets, the separation means sets a horizontal position of a separation point where the bottom sheet is separated from other stacked sheets, and a force point at which the feeding means applies a force in the conveyance direction to the bottom sheet. A paper feeding device characterized in that it is set higher than the horizontal position of the paper feeder. (2) Contact the sheet storage section that stores sheets with the top sheet of the stacked sheets in the sheet storage section, apply a force in the opposite direction to the conveyance direction to the top sheet to form a loop, and then A feeder comprising a feeding means that applies a force in the conveying direction, and a separating means that separates the bottom sheet, which receives a force in the conveying direction after receiving a force in the opposite direction to the conveying direction by the feeding means, from other stacked sheets. In a paper feeding device, the horizontal position of a separation point where the separating means separates the top sheet from other stacked sheets is lower than the horizontal position of a force point where the feeding means applies a force in the conveying direction to the top sheet. paper equipment.
