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.
Abstract:
The present invention discloses a method for fetching the identifications of the SCSI (Small Computer Systems Interface) equipment even under the circumstances interrupted by ESD (Electro-Static Discharge). The fetch method samples the identification of an SCSI equipment plurality times, and then performs a classification scheme to those sampling values to search the sampling value that is most frequently appeared. The most frequently appeared sampling value is then treated as the identification of the SCSI equipment.
Abstract:
A batch scanning method for an image input system includes sorting a plurality of image areas according to top positions of said image areas. A calibration mode is set. Next, top, bottom, left and right positions of the present image area, and the top position of the next higher image area are set to some registers. Thereafter, the image input system is calibrated when the present image area is the highest image area of the sorted areas. Then, the present image area is scanned. Afterward, a light source and a photodetector are moved to the top position of said next higher image area when at least one image area has not been scanned. The position setting step, the scanning step and the moving step are repeated until the lowest image area has been scanned.
Abstract:
An aperture switching device to be incorporated in a digital cameral for moving an aperture plate having an aperture formed thereon with respect to a lens between a shutting position where the lens is partially covered by the aperture plate with the aperture aligned with the lens and an open position where the lens is not covered by the aperture plate, includes a slide block formed on the aperture plate, a guide member mounted to the lens and having a guide channel to slidably receive the slide block therein. A driving device has an output rod movable along an arc path and mechanically coupled to the aperture plate to reciprocate the slide block along the guide channel so as to move the aperture plate between the shutting position and the open position. The mechanical coupling between the driving device and the aperture plate may include a pinion rotated by the driving device and engaged by a rack provided on the aperture plate. Alternatively, the mechanical coupling may include a transverse channel formed on the aperture plate to receive the output rod of the driving device therein. The transverse channel extends in a direction substantially normal to the movement of the aperture plate so as to convert the arcuated movement of the rod into linear motion of the aperture plate.
Abstract:
An improvement of transparent window glass holding structure for an optical scanner includes a first rack fixedly disposed in the case. The first rack has a plural number of clamps for holding and gripping the transparent window glass securely without gluing the originals table to the case as does a conventional scanner. The originals table can be easily installed and removed to facilitate the repairs and maintenance of the scanner.
Abstract:
A buffering pad for device packages is provided. The buffering pad is composed of a main member, a pair of lateral supporting members, and at least one protection member. The main member and the lateral supporting members are each formed by folding an integral piece of cardboard. At least one buckling piece is integrally formed either on the main member or on the lateral supporting member for fastening the protection member to the main member. Alternatively, a supporting glove is used to fasten the protection member to the main member. The protection member is a substantially U-shaped block which provides support and enforcement to the portion where it is fastened to.
Abstract:
A novel method for scanning multiple images in a single scanning process is disclosed. The process utilizes at least a frame holder, which contains a front frame section and a back frame section that are glued together at their top edges and are separable at least at their bottom to allow a sheet of scanning material to be placed therebetween. Each of the front and back frame sections contains a cluster of matching orientation holes on their right and left sides with a predetermined pattern to allow a computer program to achieve scan area recognition and orientation. During the scanning process, the at least one frame holder containing the image is scanned, wherein the sides of the frame holder are detected as black signals and the orientation holes are detected as white signals. Then a computer program is used to perform a previewing recognition process by detecting and carving out a scanning area corresponding to each frame holder based on the black signals and the white signals of the frame holder. The frame holder can contain a plurality of scanning windows, and more than one frame holder can be utilized in the same scanning process.
