| 20080240743 | Sheet-conveying apparatus and method for detection of multiple-sheet feeding thereof - A sheet-conveying apparatus and a method for detecting multiple-sheet feeding thereof are provided. The sheet-conveying apparatus includes a passageway, a sheet-transporting mechanism and a sheet-detecting device. The sheet-detecting device includes a first transmitter, a first receiver, a second transmitter and a second receiver. The first receiver is for receiving a first signal of a first intensity transmitted from the first transmitter. The second receiver is for receiving a second signal of a second intensity transmitted from the second transmitter. The second intensity of the second signal is not equal to the first intensity of the first signal. The sheet-detecting device further includes an analysis unit for determining if the multiple sheets are conveyed in the passageway, according to the intensities of the signals respectively received by the first receiver and the second receiver. | 10-02-2008 |
| 20080277860 | Sheet-conveying apparatus and method for detection of multifeed thereof - A sheet-conveying apparatus and a method for detection of the multifeed thereof are provided. The sheet-conveying apparatus includes a passageway, a sheet-transporting mechanism and a sheet-detecting device. The sheet-detecting device disposed in the passageway includes a first transmitter, a first receiver, a second transmitter and a second receiver. A first signal is transmitted from the first transmitter along a first transmitting path and received by the first receiver. A second signal is transmitted from the second transmitter along a second transmitting path and received by the second receiver. The second transmitting path is oblique to the first transmitting path. The sheet-detecting device further includes a control-process unit for determining if the condition of the multifeed has occurred in the sheet-conveying apparatus according to the variations in the first signal and the second signal respectively received by the first receiver and the second receiver. | 11-13-2008 |
| 20090279149 | Scanner with Simplified Document Feeding Path - A scanner with a simplified document feeding path is provided for scanning a document. The scanner includes a paper path, a conveying mechanism, an optical module and a scan window. The conveying mechanism conveys the document along the paper path. The optical module, rotatably disposed, captures an image of the document conveyed to a first position and a second position in the paper path, wherein the optical module captures a front-side image of the document at the first position and a back-side image of the document at the second position. The scan window, mounted on the optical module, is turned toward the first position and the second position as the optical module rotates, and the optical module captures the image of the document through the scan window. | 11-12-2009 |
| 20100141805 | Image correcting system and image capturing device using the same and image correcting method thereof - An image correcting system, an image capturing device using the same and an image correcting method thereof are provided. The image correcting system of the image capturing device comprises an image sensor which comprises a plurality of photo-sensing cells, each of which generates a pixel signal. The image correcting system comprises a storing unit, a decompressing unit and a correcting unit. The storing unit stores a compressed gain signal for each of the photo-sensing cells. The decompressing unit receives the compressed gain signals and then decompresses the compressed gain signals to obtain a plurality of gain signals. The correcting unit receives the pixel signals and the gain signals, and then corrects each of the pixel signals with the respective gain signal for the corresponding photo-sensing cell to obtain and output a corrected pixel signal. | 06-10-2010 |
| 20100149608 | SCANNING APPARATUS WITH FLATBED AND SHEET-FEEDING SCANNING FUNCTIONS - A scanning apparatus, which supports flatbed and sheet-feeding scanning of document, includes a first scanning unit and a second scanning unit. The first scanning unit includes a first scanning chassis which scans a document in a first main scanning direction. The second scanning unit is disposed beneath the first scanning unit and electrically connected with the first scanning unit. The second scanning unit includes a second scanning chassis which scans a document in a second main scanning direction different from the first main scanning direction. Preferably, the first and the second scanning units provide the flatbed scanning and sheet-feeding scanning functions, respectfully. | 06-17-2010 |
| 20100157381 | APPARATUS AND METHOD FOR SCANNING BOUND DOCUMENT - An apparatus for scanning a bound document is provided. The apparatus comprises a casing, an image-capturing assembly, at least a sensor and a controller. The casing has a first platen and a second platen disposed adjacent to each other, wherein the first platen having a scanning region is provided to support the bound document. The image-capturing assembly is disposed under the first platen for capturing an image of the bound document within the scanning region and generating an image signal. At least a sensor is disposed on the second platen for detecting the presence of the bound document. The sensor transmits a detection signal responsive to detection of the document presence. The controller is electrically connected to the image-capturing assembly and the sensor for executing a book-scanning mode responsive to the detection signal received from the sensor. | 06-24-2010 |
