20080226369 | APPARATUS FOR SCANNING DUPLEX DOCUMENT AND METHOD OF SCANNING DUPLEX DOCUMENT USING THE SAME - A method and apparatus for efficiently scanning a duplex document in which a scan unit sequentially scans both sides of a sheet of a duplex document by moving the sheet across a reader, and a reverse output unit to output the sheet after turning over the sheet. Therefore, since the sheet of a document can be fed and scanned while the second side of the previous sheet of the document is scanned, scanning time can be reduced. Particularly, the reduction in scanning time is very useful when multiple sheets of a duplex document need to be scanned. | 09-18-2008 |
20100142013 | IMAGE READER FOR USE IN AN IMAGE FORMING APPARATUS, AND CONTAMINATION CHECK METHOD OF GUIDE FILM FOR THE SAME - An image reading apparatus for use in an image forming apparatus includes a document glass installed on an upper side of the image reading body on which a document is placed; an image reading sensor installed under the document glass for stopping after being transferred to a predetermined position or for reciprocating in a straight direction parallel to the document glass; a cover for opening and closing the upper surface of the document glass; an automatic document feeder (ADF) for feeding the document to the position to which the image reading sensor is fixed; a document discharging plate for discharging the document fed through the automatic document feeding unit; first and second guide members for guiding to allow the document fed through the automatic document feeding unit to be discharged to the document discharging plate, the first and second guide members being installed at a predetermined interval to expose the document toward the image reading sensor; and a guide film installed to cover the interval between the first and second guide members for guiding to allow the document to be discharged to the document discharging plate. By this structure, a size of the image forming apparatus can be reduced. | 06-10-2010 |
20120044513 | Image reader for use in an image forming apparatus, and contamination check method of guide film for the same - An image forming apparatus having an image reading table includes a document glass installed on an upper side of the image reading table, to support a document; an image reading sensor installed under the document glass, to perform an image reading operation; a cover to selectively cover the document glass; an automatic document feeder (ADF) to feed a document along an image reading path, past the image reading sensor; a document discharging plate to support a document discharged from the ADF; a first guide member; a guide film attached to the first guide member; and an image forming part to form the image on a printable medium. The guide film includes a first guide film portion and a second guide film portion, the first guide film portion is in planar contact with the document glass and the second guide film portion guides the document toward the ADF. | 02-23-2012 |
