摘要： A medium supply device includes: a stacking unit in which media are stackable in a vertical direction; a first regulating unit that is provided on the stacking unit and that regulates positions of side portions of the media in a width direction; a supply unit that supplies air to more than one of the media stacked on the stacking unit so that the more than one of the media are raised and separated from each other; a transport unit that successively feeds the media that are raised and separated from each other by the supply unit; a detection unit that detects conditions of the media that are raised and separated from each other by the supply unit from outside in the width direction; a second regulating unit that is attached to an upper section of the stacking unit when the media stacked in the stacking unit are second media and that regulates positions of side portions of the second media in the width direction, the second media having a smaller dimension than first media in the width direction; and a moving unit that moves the detection unit to an area in which the second media are detectable when the second regulating unit is attached.

摘要： A sheet-shaped-medium feeder includes a housing, a mount portion that is disposed to be vertically movable in the housing and that receives sheet-shaped media, a lift that vertically raises or lowers the mount portion, a discharger that transports the sheet-shaped media stacked on the mount portion in order from an upper one of the sheet-shaped media, and first air outlets that blow air to the sheet-shaped media stacked on the mount portion at left and right edges in a feed width of the sheet-shaped media. The mount portion is changeable to a long mount portion capable of receiving long sheet-shaped media by extending an end portion of the mount portion upstream from an unchanged position in a transportation direction of the sheet-shaped media, the end portion corresponding to an upstream end portion in the transportation direction. The sheet-shaped-medium feeder has a second air outlet that blows air to at least one of left and right edges of the long sheet-shaped media stacked on the extended portion of the long mount portion.

摘要： A medium feeding apparatus includes: a placement mount on which a plurality of media are placed; a transportation mechanism that transports an uppermost medium of the plurality of media placed on the placement mount; a floating-air blowout mechanism that blows out air to float at least the uppermost medium; a suction mechanism that sucks air to cause the uppermost medium floated by the floating-air blowout mechanism blowing out air to be attracted to the transportation mechanism; and a floating-air control unit that causes the floating-air blowout mechanism to start to blow out air while the uppermost medium is being attracted to the transportation mechanism after starting to be transported by the transportation mechanism, so as to float at least a second medium located below the uppermost medium, and causes the floating-air blowout mechanism to stop blowing out air before the second medium starts to be transported by the transportation mechanism.

摘要： A feeder includes a mount board that moves vertically while allowing sheet-shaped media to be stacked thereon; a transport device allows an uppermost one of the sheet-shaped media stacked on the mount board to be sucked by a suction portion to transport the uppermost medium to a transporter and to feed the uppermost medium to a destination; left and right edge air blowers blow air to transportation left and right edge portions of upper ones of the sheet-shaped media stacked; and a tip-end air blower blows air to below the uppermost medium sucked by the suction portion from a position downstream from a transportation leading end of the uppermost medium in a transport direction. When the uppermost medium is sucked by the suction portion, the feeder performs a first operation of spacing an upwardly bent transportation leading-end portion of a second uppermost medium apart downward from the sucked uppermost medium.

摘要： A document feeder includes a document placement member that has a placement surface, a sucker that has a suction surface on which a part of a document placed on the placement surface is sucked and sucks air from a space formed between the document placement member and the suction surface, a blower that blows air into the space, and a paper feeder that conveys the document in a conveyance direction along the placement surface, wherein the suction surface is inclined relative to the placement surface such that the space is narrower toward the upstream side in the conveyance direction.

摘要： A paper feed mechanism includes: a paper storage to store sheets of paper; an air blowing unit disposed on each of both sides of the paper storage in a second direction orthogonal to a first direction corresponding to a paper conveyance direction, in which the air blowing unit blows air to a side end of each of the sheets of paper in the paper storage to float one or some of the sheets of paper in the paper storage; and a paper conveyance unit disposed above the paper storage, in which the paper conveyance unit holds, by suction, an uppermost sheet of paper among the floated sheets of paper, and conveys the uppermost sheet of paper. An air blowing position of the air blowing unit is changeable in the first direction according to information about the sheets of paper.

摘要： A feeding apparatus comprises a blower unit that is able to perform a first air blowing operation on sheets which are stacked on a stacking unit, and a second air blowing operation in which the volume of air blowing is smaller than volume of air blowing in the first air blowing operation; a feeding unit, brought into contact with the sheets stacked on the stacking unit and located on a feeding position to which feeding is performed while pressing the sheets from above, for feeding the sheets on which the first air blowing operation has been performed; and a control unit for controlling the blower unit to perform the first air blowing operation until a start of feeding by the feeding unit so as to separate the sheets stacked on the stacking unit.

摘要： A paper feeder for transporting paper sheets, includes: a head fan that blows air on the paper sheets; a suction fan that applies negative pressure to the paper sheets blown by the head fan; a switching member that changes the direction of the air from the head fan; a head shutter that blocks the flow of the air directed by the switching member; and a hardware processor that determines the blocking time of the airflow, wherein the switching member changes the air direction between a first direction for floating the paper sheets and a second direction toward the suction fan, and the hardware processor determines stop timing of the air blow in the second direction directed by the switching member as the start timing of clocking the blocking time of the airflow, based on the weight and the resistance to an external force of the paper sheets.
