Patent number: 8773730Abstract: A scan assisting fixing device and a scanner using the same are provided. The fixing device is for fixing an object to be scanned, which includes a scanning portion and a holding portion. The fixing device includes an accommodation region, a scan window and a protrusion portion. When the holding portion is loaded in the accommodation region, the scanning portion correspondingly disposed in the scan window is retained and fixed by the protrusion portion, and the position of the holding portion in the fixing device is constant, so that the scanning portion is always within the range of the field depth of the scanner regardless of the specification of the positive film holder, and the clarity of the scanned image is assured.Type: GrantFiled: May 23, 2011Date of Patent: July 8, 2014Assignee: Qisda (Suzhou) Co., LtdInventors: Yun-Bin Gu, Yong-Xiang Yi, Zhi-Hai Zhang, Jian-Chun Yu, Hong-Peng Li, Ming-Jie Zhao

Publication number: 20110286058Abstract: 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.Type: ApplicationFiled: May 20, 2010Publication date: November 24, 2011Applicant: QISDA (SUZHOU) CO.,LTDInventors: Ming-Jie Zhao, Xian-Jun Wang, Jian-Chun Yu

Publication number: 20110063599Abstract: A film holder is provided. During scanning of a to-be-scanned object, the film holder is inserted into a scanning device. The film holder includes an input portion, a guiding portion and a leveling portion. The input portion has an entrance, a channel and an exit, the channel disposed between the entrance and the exit. During scanning of the to-be-scanned object, the to-be-scanned object passes through the channel. The guiding portion connects to the input portion for guiding the to-be-scanned object. The leveling portion is disposed on one side of the channel. During scanning of the to-be-scanned object, the leveling portion leans against the to-be-scanned object. The sensing unit stably senses the to-be-scanned object. The to-be-scanned object inside the film holder is kept from being scratched and the to-be-scanned object is in smooth move during scanning.Type: ApplicationFiled: June 4, 2010Publication date: March 17, 2011Applicant: QISDA (SUZHOU) CO., LTDInventors: Xian-Jun Wang, Ming-Jie Zhao, Jian-Chun Yu
