A scanning apparatus includes a scanning module. The scanning module includes plural light emitting diodes, a porous reflective plate with plural openings, and a reflective element. When the scanning apparatus starts scanning a document, the light beams emitted by the light emitting diodes are directed to the porous reflective plate. A portion of light beams reflected by the porous reflective plate are defined as reflected light beams. The light beams penetrating through the openings are diffracted to be diffractive penetrated light beams. The reflected light beams reflected by the reflective element and the diffractive penetrated light beams are projected on the document, so that enhanced uniform illumination efficacy is achieved.

A method of capturing an image of a document is provided. First, a notebook computer having a base is provided, wherein an image pickup device is disposed on the notebook computer, and a symbol mark is formed on the base of the notebook computer. Next, a document fixer having a fixer middle mark is provided. The document is fixed by the document fixer, wherein a centerline of a long edge of the document is aligned with the fixer middle mark. Next, the document fixer is moved according to a size of the document until the fixer middle mark is aligned with the symbol mark. After the image of the document is captured, an image processing procedure is performed. By aligning the fixer middle mark with the symbol mark of the notebook computer, the document is precisely positioned and thus a sharp image with no tilted distortion is acquired.

A document fixer includes a supporting plate and a fixer body. The supporting plate includes a business card fixing recess and a clamping part. The fixer body includes a first supporting plate receiving part, an ordinary document fixing recess and a second supporting plate receiving part. When the supporting plate is received in the first supporting plate receiving part, the document fixer is adapted to fix a business card. Whereas, when the supporting plate is received in the second supporting plate receiving part, the document fixer is adapted to fix an ordinary document.

A business card case is mountable on a notebook computer. The business card case has a receptacle for storing plural business cards. The business card case includes a protrusion part, a supporting part and a restriction structure. The protrusion part is inserted in a recess of a base of the notebook computer, so that the business card case is fixed on the notebook computer. The business card to be shot by an image pickup device of the notebook computer is supported on the supporting part. By adjusting the restriction structure of the business card case and rotating said upper cover of the notebook computer, a better shooting angle is defined between the image pickup device and the document.

A thin fastening slice module includes a first fastening slice body and a second fastening slice body. The first fastening slice body includes a first surface, a first upper periphery and a first concave part. The first concave part is downwardly extended from the first upper periphery. The second fastening slice body includes a second surface, a second upper periphery and a second concave part. The second concave part is downwardly extended from the second upper periphery. The first surface has an area greater than the second surface. The first upper periphery is aligned with the second upper periphery. The second fastening slice body is connected to a front end of an image pickup device. The first fastening slice body is separated from the image pickup device. A recess structure is defined between the first fastening slice body, the second fastening slice body and said image pickup device.

An external lens device is mounted in front of a lens of an image pickup device. The external lens device includes a fixer and an external lens. The fixer includes a fixing slot and an alignment slice. The alignment slice includes a first reference mark and a second reference mark. The first reference mark is enclosed by the second reference mark. The first reference mark is arranged in the middle portion of the second reference mark. After the fixer is placed in front of the image pickup device, an outer portion of the second reference mark of the alignment slice is parallel with the lens fastening part of the lens of the image pickup device, the first reference mark is aligned with a center of the lens of the image pickup device, and the second reference mark is concentric with a lens fastening part of the lens.
