20090251743 | AUTO DOCUMENT FEEDER AND IMAGE SCANNING APPARATUS - A gap indicator device is rotatably locked to an auto document feeder openably and closably installed to a scanner device of an image scanning apparatus, is rotated by being pressed by the scanner device, and includes a pointer or a scale to indicate a state of an image reading gap, as a gap between a platen guide and an image reading portion, through which an original document passes. The pointer or the scale is located at a position where it can be visually recognized from above when a cover of the auto document feeder is opened. | 10-08-2009 |
20090311020 | AUTO DOCUMENT FEEDING DEVICE AND FEEDING METHOD - An auto document feeding device of an embodiment includes triple paper discharge rollers forming an upper paper discharge port for discharging a document at the time of one-sided reading and a lower paper discharge port for discharging a document reversed at the time of both-sided reading. A flap which covers the lower discharge port by its own weight and opens the lower discharge port by being pressed by the document discharged from the lower discharge port is provided on a shaft member of the triple paper discharge rollers. | 12-17-2009 |
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 |
