20090251744 | AUTO DOCUMENT FEEDING DEVICE AND IMAGE SCANNING DEVICE - An OUT conveying member and an IN conveying member which reach pre-scan rollers from a document tray are provided. In the case of continuously conveying a document, while a preceding document is conveyed by one conveying member, a following document is caused to stand by in the other conveying member. The documents are conveyed in the state where the distance between the preceding document and the following document is close to 0 mm. | 10-08-2009 |
20100014902 | AUTO DOCUMENT FEEDING DEVICE AND IMAGE SCANNING DEVICE - The lengths of an OUT path and an IN path are made longer than the length of a document of a main size in a traveling direction. The document of the main size stands by for conveyance in a direction of a READ document glass in a state where the entire document is contained in the OUT path or the IN path. The entrance speed of the document into the OUT path or the IN path is equal to the read speed of a scanner. The leading edge of a subsequent document is overlapped on the trailing edge of a preceding document, and the document is conveyed to the READ document glass. | 01-21-2010 |
20100109226 | AUTO DOCUMENT FEEDING DEVICE - An auto document feeding device causes an original document passing through an OUT path and an original document passing through an IN path to flow together with overlap a trailing edge of a preceding original document and a leading edge of a following original document. Before the original documents reach to a READ document glass, the auto document feeding device comprises a separating unit configured to separate an overlapping portion of the original documents. The auto document feeding device reduces a distance between the preceding original document and the following original document passing on the READ document glass to nearly 0 mm. | 05-06-2010 |
20110007370 | AUTO DOCUMENT FEEDING DEVICE - An auto document feeding device includes: a carrying member configured to carry an original from an original setting unit to an image scanning unit; a fixed guide unit configured to change a carrying direction of the original, at between the carrying member and the image scanning unit; a movable guide unit which is movable between the fixed guide unit and the carrying member; and a paper discharge unit configured to discharge the original which passed through the image scanning unit. | 01-13-2011 |
20110079953 | DOUBLE FEEDING DETECTION APPARATUS, AUTO SHEET FEEDER AND DOUBLE FEED DETECTION METHOD - A double feed detection apparatus includes a first element and a second element at positions where they are opposite to each other across a sheet, and a direction in which an ultrasonic wave or a light passes through the sheet is vertical to a conveyance direction of the sheet. An auto sheet feeder includes the first element and the second element of the double feed detection apparatus in a range from a downstream side of a joining point of an outside conveyance path and an inside conveyance path in the sheet conveyance direction to a near side of a read part. | 04-07-2011 |
20110181926 | AUTO DOCUMENT FEEDING DEVICE AND IMAGE SCANNING DEVICE - According to one embodiment, an auto document feeding device comprises: a document placing section on which documents are placed; a first gate configured to divert the documents in a first direction or a second direction; a first conveying unit or a second conveying unit configured to lead the documents to the image scanning unit; a paper discharging and conveying unit configured to lead the documents from the image scanning unit in the direction of the paper discharge tray; a reversing roller configured to switch back the documents passed through the paper discharging and conveying unit; a reversing and conveying unit configured to convey the documents from the reversing roller to the first gate; and a second gate configured to divert the documents passed through the paper discharging and conveying unit to the reversing and conveying unit. | 07-28-2011 |
20120008178 | AUTOMATIC DOCUMENT FEEDER, METHOD OF TRANSPORTING DOCUMENT, AND IMAGE READING APPARATUS - According to the embodiment, an automatic document feeder includes a first transport unit which transports a document fed from a document tray to a reading portion in a first direction after turning over the document, and a second transport unit which transports the document fed from the document tray to the reading portion in a second direction and transports the document passed through the reading portion to the reading portion in the first direction after turning over the document. When an image on one side of the document is read, the document is sorted to be transported to the first transport unit, and when images on both sides of the document are read, the document is sorted to be transported to the second transport unit. | 01-12-2012 |
20120091651 | AUTO-DOCUMENT FEEDER AND DOCUMENT FEEDING METHOD - An auto-document feeder includes: a document placing section on which an original document is placed; a sheet detection sensor configured to detect the original document, length in a feeding direction of the original document being first length larger than second length; a length detection sensor configured to detect the length of the original document while the original document is fed; a first feeding path for feeding the original document to a reading section for reading an image of the original document; a second feeding path for feeding the original document to the reading section, the second feeding path being different from the first feeding path; a switching section configured to selectively switch the first feeding path and the second feeding path; and a control section configured to divert, with the switching section, the original document to the first feeding path if the sheet detection sensor detects the original document. | 04-19-2012 |
20120112401 | AUTO-DOCUMENT FEEDER AND IMAGE READING APPARATUS - An auto-document feeder includes: a paper feeding section configured to feed original documents one by one; a first feeding section configured to feed the fed original document through a first feeding path; a second feeding section configured to feed the fed original document through a second feeding path; a third feeding section configured to alternately nip one by one the fed original documents; a determining section configured to determine that the original document is nipped by the third feeding section; and a document diverting and feeding section configured to alternately divert and feed, into the first feeding path and the second feeding path, the fed original documents and, if the preceding original document is present, after the preceding original document is detected by the determining section, feed the following original document into the first or second feeding path into which the preceding original document is not fed. | 05-10-2012 |
20120308285 | AUTO-DOCUMENT FEEDER AND AUTO-DOCUMENT FEEDING METHOD - An auto-document feeder includes plural conveying sections which have different paths to reach an image scanning section configured to scan an image on a document from a paper feeding section and which guide the document to the image scanning section, a scanning conveying section configured to alternately nip the documents one by one fed by the plural conveying sections and feed the documents in a direction of a paper discharge section through the image scanning section, a gate section which directs the documents to one of the plural conveying sections, and a detecting section configured to detect if a document is fed by the paper feeding section. | 12-06-2012 |
