摘要： An image reading apparatus includes a pair of first detection sections disposed between first positions for the feeding rollers and the separation rollers for nipping and second positions for the transport roller pair for nipping, and a pair of second detection sections disposed between the first detection sections and the second positions in the medium transport direction. The second detection sections are disposed between the first detection sections in the medium width direction, and a controller determines whether to stop transporting the medium or continue transporting the medium based on the results of detection by the first detection sections and the second detection sections.

摘要： There is provided an image reading apparatus that, when double feeding of documents is detected by a double feeding detector, transports the documents in the reverse direction of the transport direction at least until the leading edges of the double-fed documents are positioned at the upstream side of transport roller pairs by rotating a separation roller and a retard roller so as to transport the documents in the reverse direction, and that thereafter transports the documents in the transport direction by rotating the separation roller so as to transport the documents in the transport direction. When the documents are transported in the reverse direction, the image reading apparatus sets a second rotation speed of the retard roller to be faster than a first rotation speed of the separation roller.

摘要： An optical reader is provided. A transport section is capable of transporting a medium which is a reading target in forward and backward directions along a transport path. An optical reading section is installed in the transporting path. The optical reading section optically reads the medium which is transported by the transport section. A control section sets a transport direction of the medium at the time of reading of the medium on the basis of a position of the medium before or when the reading of the medium is started and a reading position of the optical reading section such that a transport distance of the medium until the reading of the medium is completed is shortened, and controls the transport section and the optical reading section.

摘要： A document feeder to reverse a document by conveying the document to a reverse path. The document feeder includes a conveyance roller to convey the document, a reverse roller provided along a conveyance path of the document conveyed by the conveyance roller to convey the document to the reverse path by changing a direction of conveyance of the document, and a reverse roller control unit to control the reverse roller to correct skew of the document. The reverse roller control unit controls the reverse roller to correct the skew of the document by striking the document conveyed by the conveyance roller against a nip formed between the reverse roller and a roller provided opposite the reverse roller to temporarily bend the document.

摘要： An original-transporting rotor configured to transport an original to an image-reading section and, after correcting skew of the original, to an original-transporting section capable of opening and closing relative to the image-reading section is provided. The original-transporting rotor is supported so as to define a variable angle with a light source provided in the image-reading section. When the original-transporting section is closed, an original-transporting mechanism is positioned by position regulating members.

摘要： A paper sheet conveying apparatus and method for an image information processor in which a paper sheet with image information recorded thereon can be prevented from a skew carriage. The paper sheet conveying apparatus includes a driving motor which is controlled to be shifted from a forward revolution mode to a reverse revolution mode or vice versa. The paper conveying apparatus further includes a power cleaving means that selectively supplies the power to a first power transmitting system and to a second power transmitting system.

摘要： Embodiments are directed at a systems, methods, and apparatuses for automatically aligning the lead edges of a document stack loaded in a scanner system. An automated jogger system includes feeder gate elements which are driven forward and backwards in an oscillating motion. This motion causes the documents in the stack to slide between each other, causing the documents to move and rotate towards the feeder gate elements, aligning the lead edges of the stack prior to being fed into the document scanner.

摘要： Provided is an image reading apparatus capable of accurately detecting an inclination amount of an original image by recognizing an edge part of the original image with high precision even when dust, stain, or the like adheres to a background part. The image reading apparatus includes: an original reader configured to read an image of an original; and a volume resistor configured to represent an original width of the original by a resistance value. The image reading apparatus further includes: a skew feed amount detector configured to set a predetermined range including the edge part of the original in a width direction as an edge detection range based on the original width, to acquire an edge image being the edge part of the original from an image within the edge detection range.

摘要： An image processing apparatus includes a platen, a fixed-document detection unit, a determination unit, and a processing-target selection unit. The determination unit determines whether the document on the platen is a left document or not when the document on the document tray and the document on the platen are detected, upon acceptance of the document-reading-starting instruction by the instruction accepting unit. The processing-target selection unit sets image data obtained by a conveyed-document reading unit as a processing target when the determination unit determines that the document on the platen is the left document, and inquires which image data obtained by the conveyed-document reading unit and a fixed-document reading unit, to be set as the processing target of the user when the determination unit determines that the document on the platen is not the left document.

摘要： An image reading apparatus is provided with a registration roller configured such that a downstream end in a sheet feeding direction of a sheet abut to correct a skew of the sheet, and a pulling roller that conveys the sheet to the registration roller. The pulling roller is disposed such that a center of an arrangement in a direction orthogonal to the sheet feeding direction of the pulling roller is located on a side of the first restricting plate from a widthwise center of the sheet conveying path.
