20100310265 | IMAGE FORMING APPARATUS - An image forming apparatus which makes it possible to resolve correction error of potential unevenness caused by insufficient mounting accuracy of an image carrier, in a relatively short time period without performing a conventional operation for removing the image carrier. The image forming apparatus includes a photosensitive drum, an exposure unit, an electrical potential sensor, a shading data ROM, and a CPU. Electrical potential data items associated with respective positions on the surface of the photosensitive drum are stored in the shading data ROM.

20130242355 | ORIGINAL READER CAPABLE OF READING ORIGINALS OF VARIOUS SIZES AND METHOD OF READING ORIGINAL - An original reader capable of being downsized without requiring a large-capacity image memory. A conveying path conveys an original. Sensors are arranged on the conveying path, for detecting the conveyed original. CCD line sensors read the conveyed original. A CPU of the image reader decides the size of the conveyed original based on the results of detection by the sensors. An image memory stores image data output from the line sensors. The CPU transmits the decided original size and the stored image data to a controller. When the CPU cannot decide the original size at a predetermined timing, it transmits one of original size candidates to the controller, as a provisional original size. When the size of the original decided afterwards is different from the provisional original size, the CPU retransmits the decided size of the original. | 09-19-2013 |
20140168731 | DOCUMENT READING APPARATUS AND DOCUMENT READING METHOD - Provided is a document reading apparatus capable of suppressing a shock that may occur when a trailing edge of a tabbed sheet passes through a roller pair. In an image reading section, when a document to be read is the tabbed sheet, a timing to start separation of the roller pair in response to detection of a trailing edge of the document is delayed by a time period corresponding to a tab length with respect to the timing to start separation when a document other than the tabbed sheet is conveyed. Thus, it is possible to prevent the shock when the trailing edge of the tabbed sheet passes through the roller pair, and to thereby suppress image reading failure due to the shock. | 06-19-2014 |
