摘要： A feeding device includes a loading portion, a lifting mechanism, a conveying unit, a sheet detector, a near-end detector, and process circuitry. The loading portion stacks a plurality of sheets. The lifting mechanism lifts the loading portion. The conveying unit conveys the sheets on the loading portion. The sheet detector detects presence or absence of the sheets on the loading portion at a specified height position. The sheet count detector detects a number of sheets conveyed by the conveying unit. The near-end detector detects a near-end state in which a stack height of the sheets on the loading portion is a specified value or less. The process circuitry controls the lifting mechanism based on a detection result of the sheet detector before the near-end state is detected, and controls the lifting mechanism based on a detection result of the sheet count detector after the near-end state is detected.

摘要： Provided are a floating restricting member restricting the floating position of a bundle of sheets; and a holding mechanism holding the floating restricting member relative to a side fence. The floating restricting member includes a sheet contact section being brought into contact with the sheets from above; and a sheet-floating restricting section restricting the floating position of the floating sheet that is floated while air is blown thereto. The holding mechanism sets the floating restricting member in the initial state where the sheet-floating restricting section restricts the floating position of the sheet, in the sheet-placing time retracted state where the sheets are pushed against the sheet contact section so that the floating restricting member is retracted, and in the sheet-ejecting time retracted state where, when the sheets are to be removed, the sheet is pushed against the sheet contact section from below so that the floating restricting member is retracted.

摘要： A sheet feeder, which is included in an image forming apparatus, includes a sheet loader, an air blowing device, a regulator, a sheet attracting device, and a sheet conveying body. The sheet loader loads a sheet bundle including a sheet and a subsequent sheet placed below the sheet. The air blowing device blows air and lifts the sheet over the sheet bundle. The regulator regulates movement of the subsequent sheet, and includes an opposing portion located upper end and separated from the sheet loader toward the downstream side of the sheet conveying direction and an inclined portion upwardly inclined relative to a vertical axis from a same position as the sheet loader to the downstream side of the sheet conveying direction. The sheet attracting device attracts the sheet lifted over the sheet bundle. The sheet conveying body conveys the sheet in a sheet conveying direction.

摘要： A paper sheet conveyance device includes a plurality of conveyance members and conveys a paper sheet while performing temporary stop of conveying and then restart of conveying. Two paper sheets sequential in a conveyance direction stop together in a state of the temporary stop, driving a first transfer member to which a preceding first paper sheet that is one of the two paper sheets is opposed and a second conveyance member to which a following second paper sheet that is the other paper sheet is opposed is stopped and restarted synchronously for the temporary stop and the restart. A stop position information acquisition unit acquires information on a position on the conveyance path at which the second paper sheet stops in the state of the temporary stop, and a timing for stopping the conveying after the conveying is restarted is controlled according to the acquired information.
