摘要： A sheet feeding device includes: a sheet stacking member; an air blowing unit configured to blow air onto the sheet bundle placed on the sheet stacking member to suspend multiple sheets of the sheet bundle; a lifting/lowering unit configured to lift/lower the sheet stacking member; an optical reflection sensor configured to detect a suspended sheet suspended by the air blowing unit; and a control unit configured to control the lifting/lowering unit based on an output value of the optical reflection sensor. The optical reflection sensor is configured to be capable of detecting an area corresponding to multiple sheets in a sheet suspension zone extending between a non-suspended sheet bundle and a conveying member configured to convey an uppermost sheet of the multiple suspended sheets. The non-suspended sheet bundle is made up of sheets not suspended during a period when air is blown by the air blowing unit.

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 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.

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 sheet feeding device includes a sheet stacking table, an air blower, a feeder, and an air sucker. The sheet stacking table stacks a bundle of sheets. The air blower blows air to the bundle of sheets to float an uppermost sheet from the bundle of sheets. The feeder feeds the uppermost sheet. The air sucker sucks air in such a direction that a sheet in vicinity of the uppermost sheet moves away from the feeder. The air sucker includes a suction nozzle to suck air, a suction fan to generate a negative pressure, a suction duct to communicate the suction nozzle with the suction fan, and an opening-and-closing mechanism to shut off and release ventilation in the suction duct.

摘要： A sheet feeding apparatus includes a sheet stacker, an air blower, a float regulator, and a controller. The sheet stacker stacks sheets. The air blower blows air to the sheets. The float regulator regulates a floating position of the sheets and is movable between a float regulating position at which the float regulator regulates floating of the sheets and a retracted position. The controller transmits position information of the float regulator to a notification device.
