An apparatus for controlling curl in sheets between two transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert sheets (Bernoulli effect) towards the curved baffle. By positioning the curved baffle between the two transports and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the trajectory of the sheets and ensure acquisition by the downstream transport.

A printer includes: a motor driving a transport member according to an operational parameter, to transport media along a media path from a media supply to a printhead; a first distance sensor disposed on a first side of the media path to measure a first distance between the media and the first distance sensor; and a controller configured to: receive the measured distance; detect curling of the media based on the first measured distance; and responsive to detecting curling of the media, update the operational parameter at the motor.

A background image is acquired by imaging an opening plate as a background of an original document in a state where the original document is not arranged. Next, an original document including background image is acquired by imaging the same range as the background image in a state where the original document is arranged on an upper surface of the opening plate. Next, a difference image is generated by subtracting the background image from the original document including background image. In addition, an inverse difference image is generated by subtracting the original document including background image from the background image. A region of the original document is detected based on the difference image and the inverse difference image.

A feeding device includes: a feeder that feeds a first medium disposed on a top of plural media loaded; a detector that detects at least one of a curved state and an inclination of the first medium and following media including a second medium disposed immediately below the first medium; and a modifier that modifies a condition related to a feeding operation of the feeder based on the at least one of the curved state and the inclination detected by the detector.

A flatbed scanner includes a flatbed document scanner body accommodating a transparent plate for supporting a physical document and a document cover, which includes a sheet member with an expanse covering at least a substantial area of the transparent plate. The rectangular document cover has an underside and a movable carriage extending across the rectangular transparent plate in a transverse direction. The movable carriage carries a camera or an optical system for a camera. The sheet member of the rectangular document cover is magnetic or carries one or more magnetic plates, so as to be magnetically attracted towards the movable carriage and exert a pressing force on the physical document when supported on the rectangular transparent plate. A compressing force is thereby applied to an original document resting at an area at which the movable carriage currently is located while scanning a line of the original document.

An image reading apparatus according to an embodiment includes a first sensor, a roller, a correction unit, a second sensor, a control unit, and a scanner. Upstream to downstream positions with regard to a transportation direction of the sheet are determined in the following order: the first position, a second position, a third position. The first sensor detects the presence or absence of a fold of the sheet in the first position. If it is detected in the first position that the fold is present, the roller transports a sheet in a reverse transportation direction. The correction unit corrects the fold in the first position. The second sensor detects the presence or absence of the fold in the second position. If it is detected in the second position that the fold is present, the control unit controls drive of the roller in such a manner that the sheet is transported up to the first position in the reverse transportation direction. The scanner reads an image on the sheet of which the fold is corrected in the first position.

An image recording apparatus includes a feed tray configured to accommodate a sheet-shaped medium, the sheet-shaped medium including at least one of a first sheet-shaped medium or a second sheet-shaped medium, and a recording device configured to record an image on the sheet-shaped medium fed from the feed tray. The feed tray includes a first accommodation portion configured to accommodate a roll, in which the first sheet-shaped medium is rolled in a roll shape, a second accommodation portion configured to accommodate a plurality of the second sheet-shaped media in a stacked state, and a display portion that displays setting information on setting of the sheet-shaped medium.

There is provided an image forming device having a guide member that guides a sheet having passed through a fixing device to a pair of sheet ejection rollers, wherein the pair of sheet ejection rollers has pairs of sub-rollers installed at a rotary shaft at predetermined intervals, and a nip is formed by a pair of sub-rollers facing each other, the pairs of sub-rollers includes a specific pair of sub-rollers that nips an end region in a width direction orthogonal to a sheet conveyance direction when a sheet of a prescribed size passes, and the guide member includes a pressing member that presses a curl caused at an end region in the width direction of the sheet on a more upstream side in the sheet conveyance direction than a position where a leading end of the sheet enters a nip between the specific pair of sub-rollers.

A flatbed scanner includes a flatbed document scanner body accommodating a transparent plate for supporting a physical document and a document cover, which includes a sheet member with an expanse covering at least a substantial area of the transparent plate. The rectangular document cover has an underside and a movable carriage extending across the rectangular transparent plate in a transverse direction. The movable carriage carries a camera or an optical system for a camera. The sheet member of the rectangular document cover is magnetic or carries one or more magnetic plates, so as to be magnetically attracted towards the movable carriage and exert a pressing force on the physical document when supported on the rectangular transparent plate. A compressing force is thereby applied to an original document resting at an area at which the movable carriage currently is located while scanning a line of the original document.

A curl-correcting device includes a roller, a belt, a pair of rollers, and an adjuster. The roller is disposed facing the convex side of a curled sheet. The belt is rotatable in a predetermined direction to convey the sheet sandwiched between the roller and the belt. The pair of rollers is located at positions of an upstream side and a downstream side in a rotation direction of the belt, and each abuts the roller via the belt. The adjuster adjusts a winding angle at which the belt is wound around the roller by varying an interval between the pair of rollers in the rotation direction of the belt.
