Abstract: 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.

Abstract: A sheet feeding device includes a sheet loading table on which a bundle of sheets is stacked, an identification mark on an end face of the sheet loading table, and an imaging unit to identify the identification mark.

Abstract: A sheet feeding device includes a sheet stacker configured to stack a sheet bundle; a blower configured to float a sheet on an upper portion of the sheet bundle; a conveyor configured to convey the sheet floated by the blower; a lift configured to lift up and down the sheet stacker; a first reflective optical sensor configured to detect the sheet floated by the blower; a second reflective optical sensor configured to detect the sheet bundle and a side face of the sheet stacker, the side face including a detection region to be detected by the second reflective optical sensor and a non-detection region not to be detected by the second reflective optical sensor; and circuitry configured to control the lift based on a detection result of the first reflective optical sensor and a detection result of the second reflective optical sensor.

Abstract: A sheet conveying device includes a sheet loader, a loader elevating device, a sheet presence detector to detect a sheet on the sheet loader, and circuitry configured to determine whether the bundle of sheets is loaded on the sheet loader based on a detection result of the sheet presence detector and to control movement of the loader elevating device. The circuitry is configured to cause the loader elevating device to lift the sheet loader to a second position in response to a detection result of the sheet presence detector indicating absence of the sheet on the sheet loader at a first position and not to determine absence of the sheet when the circuitry causes the loader elevating device to lower the sheet loader from the second position to the first position after the circuitry causes the loader elevating device to lift the sheet loader to the second position.

Abstract: 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.

Abstract: A sheet-member separation device includes a first air blower, an attractor, a conveyor, a second air blower, and an adjuster. The first air blower blows air onto a front side of a stack of sheet members in a sheet-member conveyance direction. The attractor attracts an uppermost sheet member floated from the stack of sheet members by the air blown from the first air blower. The conveyor conveys, in the sheet-member conveyance direction, the sheet member attracted by the attractor. The second air blower blows air toward a lateral side of the sheet member. The adjuster moves the second air blower and the attractor together to adjust positions of the second air blower and the attractor in the sheet-member conveyance direction.
