A latch-free button structure and its design method that can be applied to most electronic devices. The button includes a body, a wing plate, a positioning plate and a contact rod. The top end of the wing plate joins with the side edges of the button body and the positioning plate joins with the lower end of the wing plate. The contact rod is attached to the bottom section of the button body. If the height from the bottom of the contact rod to the contact point on the circuit board is B; the height from the bottom section of the button body to the surface of the housing is C; the height of the wing plate is A; the height of the sidewall of the button cover close to the button body is D and the height from the uppermost section of the button body to the top end of the wing plate is E, the value of A, B, C, D and E must follow the inequality relationships E&#x2212;B&#x3e;D, E&#x2212;D&#x3e;A, and D&#x3e;A&#x2267;C&#x2267;B.

A scanning module includes a body casing having a light passage slit thereon, a plurality of reflecting mirrors located inside the body casing, a light-channeling apparatus, and a light guiding body. The light-channeling apparatus includes a first light-guiding tube positioned between a light source and a document, and a second light-guiding tube positioned between the document and the light passage slit. The light-guiding body is positioned inside the first light-guiding tube or the second light-guiding tube.

Light-channeling apparatus and method

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.

Compensation apparatus for image scan

A scanning method, applicable for a flatbed scanner with transparent scanning function. A plane light source with a distribution range covering the region to be scanned of a transparent document is provided. The distribution range of the plane light source is read by preview scanning, such that the position of the transparent document is captured.

[Scanning method]

An installation for increasing the scanning range along the axial direction of the light source. The installation includes a light source and a transparent glass panel. The light source provides a light beam necessary for scanning a document. The transparent glass panel has a coating thereon for lowering light transparency near the mid-portion of the light axis relative to either end.

An optical scanner suitable for scanning a vertical object. The optical scanner has a scanning body, a focusing device and a scanning module. The scanning body has a transparent window, the focusing device has an arm, a reflective mirror and a lens. One end of the arm is coupled to the scanning body, and the reflecting mirror and the lens are disposed on the arm. The scanning module is disposed in the scanning body with a shell, a lens and an optical sensor. The shell has a light cone opening, and the lens and optical sensor are disposed within the shell. The image of the vertical object is focused by the focusing device on the transparent window, incident to the scanning module via the light cone opening, and refracted by the lens to form an image on the optical sensor.

Optical scanner

A linear guiding mechanism for a platform type optical scanner. A V-shaped track is installed inside a casing and positioned parallel to the travel path of a carrier chassis containing a system of optical devices. The upper section of the V-shaped track has a pair of support surfaces forming an included angle. The V-shaped track supports a positioning wheel or a positioning bump attached to the carrier chassis. The carrier chassis moves along the longitudinal direction of the V-shaped track when driven by a driving system. The V-shaped track may be constructed from a pair of monorails so that the driving belt may move inside the space between the monorails. An additional positioning structure may attach to the interior sidewall of the casing to serve as a retainer for the chassis in an initial position.

Linear guiding mechanism

A paper-separating plate is adapted for a paper-separating mechanism having a paper-separating roller. The paper-separating plate placed around a side of the paper-separating roller comprises a main body and a cushion. The main body has a surface and a plurality of grooves and the grooves are positioned on the surface. The cushion is positioned on the surface of the main body and covers the grooves. The cushion positioned over the partial grooves is elastically pressed onto the paper-separating roller. The grooves are linear and the direction of extending the linear grooves is substantially parallel with the axis of the paper-separating roller, the linear grooves neighboring one another or each other. Besides, the cushion is made of flexible material and the main body is made of rigid material.

Method and apparatus for fastening adjustable optical lenses

Embodiments of the claimed subject matter comprise a movable locking device for a scanner. In one embodiment, the movable locking device is used to affix a moving mechanical part inside a scanner, such as inside an optical chassis of the scanner. In this embodiment, the scanner comprises a platform, a lifting cover and a hinge set. The scanner uses the hinge set to allow the lifting cover to rotate relatively to the platform. The locking device includes a movable structure member and a buckling groove, in which the movable structure member includes a stopping piece and a holding rod used as the axis of rotation of the hinge set.

A photographic film scanning device includes an image scanner including a first casing having a transparent top surface and an optical scanning module movably arranged inside the first casing. A film driving assembly includes a second casing having a detachable bottom removably positioned on the top surface of the first casing. A light-transmitting window is defined in the bottom, having a length and a width. A film driving mechanism is arranged inside the second casing, including a film container for containing a length of film and a film spool for windingly receiving the film roll, respectively arranged on opposite longitudinal ends of the window. A motor drives a toothed wheel engaging perforations defined in the film for moving the film across the length of the window. A light source projects light through the film and the window toward the optical scanning module for performing scanning operation of the film.

Photographic film scanning device

A light-channeling apparatus for a scanning module comprises a first light-guiding tube, a second light-guiding tube, and a collimating lens positioned inside the first light-guiding tube. The first and second light-guiding tubes are attached to a body casing of the scanning module. The scanning module uses the first light-guiding tube having the collimating lens to channel light from a light source to a scanning region and uses the second light-guiding tube to channel light reflected from the scanning region to a light passage slit on the body casing, to minimize dispersion of light from the light source and keep external light out of the light transmission pathway.

An optical scanner is provided with a carrier, a casing, a driving unit and a transmission unit. The carrier has a connecting unit and an optical system mounted thereon. The casing has a guiding rail formed as integral unit on the interior wall. The guiding rail has at least a fastener for latching onto the connecting unit of the carrier. The transmission unit links up the driving unit and the carrier. The driving unit drives the transmission unit and then the transmission unit pulls the carrier along the guiding rail through the linkage between the connecting unit and the fastener.
