20080288852 | MULTICARRIER COMMUNICATION SYSTEM CAPABLE OF SWITCHING MODULATION SCHEMES DURING COMMUNICATION - A multicarrier wireless communication system is capable of switching the modulation scheme used by each carrier during communication. This communication system includes error detectors for detecting error bits separately for respective carriers by comparing the data block of each carrier before and after correction. The modulation scheme used by a particular carrier is switched to an appropriate modulation scheme, when the S/N ratio of the particular carrier is deteriorated or improved, on the basis of the information about the corrected error bits. | 11-20-2008 |
20090136275 | Image reading apparatus and image forming system - An image reading apparatus includes an image reader, a document feeder, and a document retainer. A document feeder feeds the document to the image reader, and the image reader reads an image of a document. The document feeder discharges the document onto a stacker after the image of the document has been read. The document feeder is pivotal relative to the image reader. When the document feeder opens relative to the reader at an angle, the document retainer presses the document against the stacker. | 05-28-2009 |

20120057285 | IMAGE FORMATION APPARATUS - An image formation apparatus includes a first unit and a second unit connected with each other, a first exterior cover covering a part of the first unit, a second exterior cover covering a part of the second unit and formed with a cover main body and an extension extending from the cover main body. A third exterior cover is provided between the first exterior cover and the second exterior cover and overlaps with while contacting the extension of the second exterior cover. | 03-08-2012 |
20120281247 | MULTIFUNCTION APPARATUS - A scanner is mounted on a printer. A printer lid is pivotally mounted to the printer, and is moveable to open and close. A scanner lid is pivotally mounted to the scanner, and is moveable to open and close. A printer locking member and a scanner locking member are pivotally mounted to the scanner. Opening the scanner lid causes the printer locking member to pivot to lock the scanner to the printer. Opening the printer lid causes the scanner locking member to pivot to lock the scanner lid to the scanner. A scanner having a lid is pivotally mounted on a printer. When the lid is pivoted to open, a stopper may pivot together with the lid and abut the scanner, thereby stopping the lid. The stopper may pivot together with the lid and the scanner and abuts the printer, stopping the lid and the scanner. | 11-08-2012 |
