A stacking apparatus includes a conveyance unit, a stacking unit, and a separation member supply unit. The conveyance unit conveys sheets for circuit board. The stacking unit stacks the sheets. The separation member supply unit supplies a separation member to separate the stacked sheets at any position. The separation member supply unit places the separation member on the sheet in being conveyed.

A sheet-material supply device includes a lift, a sheet-material detector, and a sheet-material retaining conveyor. The lift elevates sheet materials in a stacked state. The sheet-material detector detects that an uppermost sheet material of the sheet materials in the stacked state has reached a predetermined height. The sheet-material retaining conveyor retains and conveys the uppermost sheet material that has reached the predetermined height. The sheet-material supply device stops elevation of the sheet materials in the stacked state when the sheet-material detector detects that the uppermost sheet material has reached the predetermined height. The sheet-material retaining conveyor is disposed to be movable in a direction in which the sheet materials in the stacked state elevate.

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.

A sheet discharging device includes a shift tray 202 on which a sheet P1 is stacked, a discharging roller 6 that discharges a sheet P2 onto the shift tray 202, a blowing device 230 that sends air to a lower surface of the sheet P2 discharged by the discharging roller 6, a blocking member 231 that blocks air sent to the lower surface of the sheet P2 from a blowing port 230-2 of the blowing device 230, and a control unit that controls the blocking amount of the blocking member 231. The blocking amount is determined based upon sheet information including sheet-type information, sheet-size information, and sheet-thickness information, for example.

A fold-enforcing assembly includes a fold-enforcing device, a moving device to move the fold-enforcing device in a direction of a fold of a sheet bundle, and control circuitry. The fold-enforcing device includes a pressing member pair to nip and press the fold of the sheet bundle in a direction of thickness, a pressing mechanism to pressurize and depressurize the pressing member pair, and a driver to drive the pressing mechanism. Controlled by the control circuitry, the moving device moves the fold-enforcing device in accordance with a size of the sheet bundle in the direction of the fold; pressing mechanism pressurizes the pressing member pair to press a first end portion of the sheet bundle in the direction of the fold; the moving device moves the fold-enforcing device to a second end portion of the sheet bundle; and pressing mechanism depressurizes the pressing member pair in the second end portion.
