摘要： A sheet conveying device includes an attractive separation unit and a contacting and separating device. The attractive separation unit includes an attraction belt arranged to face the upper surface of a sheet stack, two rollers that stretch the attraction belt taut, with the upstream-side roller in the sheet conveying direction supported to be movable in substantially upward and downward directions within a predetermined range with respect to the upper surface of the sheet stack, and a charging device which charges a surface of the attraction belt. The contacting and separating device swings the attractive separation unit to make the attraction belt come into contact with and separate from the sheet stack, with a fulcrum of the swing of the attractive separation unit set to a position upstream in the sheet conveying direction of the upstream-side roller in the sheet conveying direction.

摘要： A sheet conveying device includes an attraction belt, multiple rollers, a charging device, and a contacting and separating device. The attraction belt is arranged to face the upper surface of a stacked sheet stack. The multiple rollers stretch the attraction belt with tension. The charging device charges a surface of the attraction belt. The contacting and separating device causes the attraction belt to come into contact with and separate from the sheet stack, with different tensions set for the attraction belt at a contact position in contact with the uppermost sheet of the sheet stack and the attraction belt at a separation position separate from the sheet stack.
