| 20110286058 | SCANNING METHOD OF SCANNING APPARATUS AND SCANNING APPARATUS - A scanning method of scanning apparatus and a scanning apparatus are provided. Firstly, when the scanning apparatus is in the default reflective document scanning state and a document is placed in the scanning apparatus, the scanning apparatus automatically activates reflective document scanning function to perform scanning. Next, a document holder is disposed in the feeding entrance of the scanning apparatus, wherein after the scanning apparatus activates the transmissive document scanning state and the document is placed in the document holder, the scanning apparatus automatically activates transmissive document scanning function to perform scanning. The scanning method automatically activates corresponding scanning function without performing document recognition, incurs lower power consumption, produces fast recognition, and is applicable to various scanning apparatuses having both reflective document and transmissive document scanning function. The scanning apparatus has well-designed structure, incurs lower manufacturing cost, and does not require complicated light emitting element and light measuring element. | 11-24-2011 |
| 20110085210 | LIGHTING STRUCTURE AND SCANNING DEVICE - The invention relates to a lighting structure and a scanning device. The lighting structure comprises a light source and a light guide. The light source comprises a plurality of light emitters spaced within a first plane along a first direction. The light guide comprises a plurality of light guiding bodies arranged in parallel. The light guiding bodies form a one-to-one correspondence with the light emitters and have a light entering surface and a light leaving surface which are both a curved surface. The curve of the intersection between each light leaving surface and a first cross-section has a first curvature radius, and the curve of the intersection between each light entering surface and a second cross-section has a second curvature radius, wherein the first cross-section is perpendicular to the second cross-section, and the first cross-section and the second cross-section are both perpendicular to the first plane. | 04-14-2011 |
| 20110075925 | FILM SCANNING METHOD - A film scanning method is provided. When the film is judged as a negative film, the scanning device sets the scan exposure time for the film according to the base background color of the film. The negative film is scanned for the scan exposure time, wherein, the film passes through the scanning device at one time so as to complete the above judge of the film type and scanning of the film. The film scanning method automatically completes the recognition of film type, performs accurate scanning based on the scan exposure time, expands the dynamic range and reduces noise impacts, so as to obtain a scanned image with higher accuracy. | 03-31-2011 |
| 20110063692 | METHOD FOR AUTOMATICALLY IDENTIFYING SCAN REGION BOUNDARY - A method of automatically identifying a scan region boundary, used for scanning a document under a non-unified background, includes: reading a reference linear scan data by a scanning device, the scanning device analyzing brightness values in each row of the reference linear scan data and determining a reference range value according to the brightness values in each row; and during scanning a document, the scanning device comparing brightness values of a linear scan data with the reference range value so as to determine the scan region boundary. The method confirms the scan boundary of a document and is not subjected to a backlight element or a document carrier. The method identifies the boundary of a document under a non-unified background, is applicable to scanning transparent and reflective documents and has strong resistance against environmental interference, not only simplifying the scanning device but also enhancing the automatic performance. | 03-17-2011 |
| 20110032582 | SCANNING DEVICE - The invention is directed to a scanning device including an image sensing module, a first carrier, a second carrier and a holder. The image sensing module includes an image sensor for reading the image of an original document. The first carrier is for carrying the original document in a dynamic scanning mode. The second carrier is for carrying the original document in a static scanning mode. The holder, used for fixing the first carrier and the second carrier, includes a transitional portion disposed between the first carrier and the second carrier. There are a first distance between the image sensor and the bottom surface of the first carrier and a second distance between the image sensor and the bottom surface of the second carrier, wherein the first distance is greater than the second distance. The dual-mode design facilitates the assembly of carriers and avoids the dust entering the scanning device. | 02-10-2011 |
| 20100039681 | SHEET-FED SCANNING DEVICE WITH CLEANING MECHANISM - A sheet-fed scanning device with cleaning mechanism is provided. The sheet-fed scanning device includes a housing, a scanning module for scanning a fed-in document, and a cleaning curtain whose one end is fixed on the sheet-fed scanning device. The cleaning curtain is disposed in a sheet-fed direction at the front end of the scanning module, and the edge of the other end of the cleaning curtain is elastically in contact with the fed-in document for cleaning a to-be-scanned surface of the fed-in document. The invention is simple in structure and effective in cleaning the fed-in document. The cleaning mechanism does not cost much, but avoids the scanning quality being affected due to the large friction of the cleaning element. The cleaning mechanism ensures long-term cleanness of the to-be-scanned surface of the fed-in document as well as the cleanness of the glass window of the scanning module and the scanning quality. | 02-18-2010 |
