Abstract: A method for scanning a selected target image area of a document includes steps of establishing in a scanner a first optical path by a first focusing lens; using the first focusing lens to preview the document and select from the whole document image a selected image area; moving the first focusing lens out of the first optical path and move a second focusing lens into the optical path to establish a second optical path in the scanner; and using an optical scanning module in the scanner and the second focusing lens to scan the selected image area of the document to obtain the desired target image.

Abstract: A compensation apparatus for image scan, applied to an optical scanner with a platform, on which an object to be scanned is disposed. The optical scanner has a photosensitive apparatus with a set of scan photosensitive devices and a storage apparatus. When the object is scanned by the set of scan photosensitive devices, a scanned image is obtained and saved in the storage apparatus temporarily. The compensation apparatus has a set of calibration boards, a set of calibration photosensitive devices and an image processor. The set of calibration boards has two calibration boards located at two sides of the platform. The set of calibration photosensitive devices is located at two sides of the set of scan photosensitive device. The image processor is used to extract and compare the calibrated image, so as to adjust the scanned image.

Abstract: An optical scanning module comprising an outer cover, a plurality of fixing elements, a plurality of reflecting mirrors, a plurality of buffer pads, a lens, an image capturing device and a light source is provided. Each of the fixing elements disposed on the inner wall of outer cover comprises a clip and a reflecting mirror supporting holder. The reflecting mirror supporting holder is manufactured as an integrative unit on the inner wall of the outer cover. The clip has a crooked portion that holds the reflecting mirror and the buffer pads on the reflecting mirror supporting holder. Further, when the reflecting mirror is fixed on the reflecting mirror supporting holder by the clip, the buffer pads are set between the mirrors and the holders. Therefore, the bending or the curling phenomenon of reflecting mirrors and the distortion of image quality can be effectively prevented.

Abstract: A transmission rope for driving movable mirror modules of an image scanning device is disclosed. One end of the transmission rope is located at a locating member. The other end of the transmission rope is first wound on a guide wheel of the second movable mirror module and then held by a rope holder of the first movable mirror module and then the transmission rope is sequentially traveled through several auxiliary guide wheels and a driving motor and then wound back onto the guide wheel of the second movable mirror module and finally fixed at a tension adjuster. The section of the transmission rope between the rope holder of the first movable mirror module and the guide wheel of the second movable mirror module and between the guide wheel of the second movable mirror module and the locating member has better tensile strength than that of the other section of the transmission rope so as to minimize the length deformation during driving the first and second movable mirror modules.

Abstract: An optical scanner with adjustable resolution includes a casing, an optical path means, a driving means and a movable motor. The casing has a scanning path for the optical path means reciprocally moving therein for scanning. The driving means includes a belt-pulley means and a first friction wheel. The motor has an output shaft upon which a second friction wheel is mounted. The second friction wheel makes contact with the first friction wheel for driving the belt-pulley means to move the optical path means to perform scanning. The movable motor may change contact position between the first and second friction wheel and consequently change moving speed of the optical path means. As a result, the resolution of the scanner may be changed and adjusted.
