A sheet conveying device includes a sheet placement table, a sheet discharge table, a conveyance mechanism, raising/lowering mechanism, and a raising/lowering control portion. The sheet discharge table is located below the sheet placement table. The conveyance mechanism conveys a sheet placed on the sheet placement table onto the sheet discharge table via an execution position at which image processing is executed by an image processing portion. The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism in accordance with a clearance that is defined by a height from the sheet on the sheet discharge table to the sheet placement table, so as to maintain the clearance to be equal to or higher than a set value.

A sheet feeding device includes a sheet tray, a blower, a feeder, an illuminator, an imager, and circuitry. The sheet tray stacks sheets. The blower blows air to the sheets stacked on the sheet tray and floats an uppermost sheet of the sheets. The feeder feeds the uppermost sheet. The illuminator illuminates the uppermost sheet floating. The imager captures an image including the uppermost sheet illuminated by the illuminator. The circuitry adjusts an imaging condition based on the image captured by the imager.

The invention relates to a device for feeding products in sheets into an insertion device before a digital printer, including a lifting system for a stack of laminar elements, which in turn includes an extraction mechanism for the last board, an insertion system with an advance mechanism, a rotation system for the stack(s), a positioning stop, connected to an advance and reverse mechanism, a squaring and scaling station, able to create a loading and accumulating hopper, and a telescopically-adjustable transportation system, with the capacity to move the previously-scaled sheets until the insertion device is fed.

A sheet feeder apparatus includes a width detector for a sheet placed on a sheet placement portion, a conveyor for conveying sheets while separating the sheets one by one, a first detector for detecting a sheet having a first width at a plurality of first positions, a second detector for detecting a sheet having a second width that is not detected by the first sheet detector at a plurality of second positions, and a controller for determining skewing of a sheet based on a result of the detection of the sheet performed by the first detector if the width of the sheet is the first width, and determining skewing of a sheet based on a result of the detection performed by the second detector if the width of the sheet is the second width.

A recording device includes a recording unit configured to perform recording on a recording target medium, a first conveyance path that is a conveyance path of the recording target medium including an opposite position that faces the recording unit, and conveyance of the recording target medium in a first direction, a second conveyance path being coupled to the first conveyance path at a position downstream of the recording unit in the first direction, the second conveyance path being coupled to the first conveyance path also at a position upstream of the recording unit in the first direction and configured for conveyance of the recording target medium to the first conveyance path with a surface of the recording target medium inverted, and an insertion port configured to enable insertion of a recording target medium as an insertion material to the second conveyance path from outside.

A sheet stacker includes a sheet stacking portion, a pair of sheet restrictors, a sheet feeder, and a position detector. A bundle of sheets is stacked on the sheet stacking portion in a stacking direction, and the sheet stacking portion moves in the stacking direction. The pair of sheet restrictors move in a width direction to regulate a position of the bundle of sheets in the width direction. The sheet feeder feeds a top sheet of the bundle of sheets at a sheet feeding position in a sheet feeding direction. The sheet feeding position is disposed at a top of the bundle of sheets in the stacking direction. The position detector is disposed between the pair of sheet restrictors in the width direction and above the sheet feeding position in the stacking direction. The position detector detects a position of the pair of sheet restrictors in the width direction.

A supply device configured to supply a medium to a processing unit configured to perform processing on the medium, the supply device including an accommodating unit configured to accommodate a plurality of the media in a state of being stacked therein and a vibration imparting unit configured to contact ends of the plurality of media accommodated in the accommodating unit to impart vibration to the medium.

A document conveyance device includes a sheet feeding tray, a conveyance mechanism, a discharge tray, a document pressing member and a supporting mechanism. The document pressing member comes into contact with an upper face of the document discharged from a conveyance path and presses the document downward. The supporting mechanism is configured to be provided in the sheet feeding tray, to support the document pressing member, to allow a shifting of the document pressing member according to an operation for shifting the document pressing member in a discharge direction of the document or an opposite direction to the discharge direction and to inhibit the shifting of the document pressing member against a force applied to the document pressing member by the discharged document.
