A document holding fixture for a vertical optical scanner. The fixture has a main body, a transparent panel, four linking bars, a document cover panel, and a document backing plate. The document holding fixture uses a simple four linking bar system to maintain a constant parallelism between the document cover panel and the surface of the transparent panel. Weight of the document cover panel provides necessary pressure to press a scan document firmly onto the glass surface of the transparent panel. To facilitate single hand document insertion, a stationing device is used to freeze the document cover panel when the panel reaches a horizontal position.

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.

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.

A chassis locking apparatus capable of being unlocked spontaneously is used for fixing the chassis in a scanner. The locking apparatus includes a groove interlinking next to the electric socket, a push rod in the groove, and a revolving locking element. By means of the strength of inserting the plug into the socket on the scanner, the push rod is pushed to move along the groove and hit the locking element, which is originally fixed on the chassis, to make the locking element rotate so that the chassis locking apparatus can be unlocked spontaneously. Therefore, no effort is necessary for a user to unlock the chassis locking apparatus by hand before using the scanner, which is convenient and timesaving.

An optical image scanning device includes a casing having a document supporting plate and a top cover. The top cover has an underside surface coated with a fluorescent material thereon. An optic module includes a light source for projecting an exciting light onto the fluorescent layer whereby the fluorescent material is excited by the exciting light to emit a scanning light. The scanning light transmits through a light-transmittable document and projects an image of the document onto reflective mirrors for guiding the scanning light through a focusing lens. The focusing lens focuses the light onto a image sensing device. A reflective type light source is selectively arranged in the optic module for selectively projecting a light onto a document formed on a non-transmissive medium that is positioned on the document supporting plate.

A scanning apparatus with the appearance of a pen for scanning a small-sized document has the casing, the cap, the input slot and the output slot for inputting and outputting the small-sized document on the casing, respectively, the transmission apparatus for driving the small-sized document, the light source for emitting the light, the photoelectric sensing device for receiving a light signal reflected by the small-sized document and then outputting a digital data of captured image to the control processing unit. The scanning apparatus also has 1394 interface connector or USB (Universal Serial Bus) connector to transmit the digital data stored in the control processing unit to the terminal operating system such as the computer, the Personal Digital Assistant (PDA), or the cellular phone for editing or printing. The scanning apparatus of the invention is easy to carry and can be operated anywhere and anytime.
