    Abstract: A scanhead of an imaging apparatus for providing image illumination uniformity for imaging of a media sheet, and a method thereof, are disclosed. The scanhead includes a lens, a lens shading plate and a sensor array. The lens is capable of receiving light reflected from the media sheet and focusing the received light. The lens shading plate is capable of assuming a lens shading plate position of a plurality of lens shading plate positions between the lens and the sensor array for receiving the light focused by the lens. The lens shading plate, on assuming the lens shading plate position, is capable of adjusting the light received from the lens for focusing the light onto the sensor array, thereby providing image illumination uniformity, for the imaging of the media sheet.

    Abstract: The present invention relates to a scanning module, which is capable of integrating optical paths of illuminating and imaging for size reduction, and improving the quality of scanned image by using optical polarizers for filtering, and further achieving the same effect as the “projection scanning” digital camera. The scanning module comprises: a light source, a first polarizer, a quarter-wave plate, a polarizing beamsplitter, an image detection device, and a second polarizer. The light from the light source consists of both a first-polarized and a second-polarized light. The first polarizer is placed in front of the light source that only allows the first-polarized light to pass through. The optics unit directs the first-polarized light to a scanning object and transforms the reflected light into the second-polarized light before receiveded by the image detection device for image acquiring. The second polarizer is placed between the optics unit and the image detection device for allowing only the second-polarized light to pass through such that the influence on the image detection device from the light source can be eliminated.

    Abstract: An optical reading device of a scanning apparatus includes two light sources and a movable lens. The first light source emits a first light when the optical reading device is operated in a flatbed scanning mode. The second light source emits a second light when the optical reading device is operated in a sheetfed scanning mode. The movable mirror is selected to allow for passing the first light without being obstructed by the movable mirror in the flatbed scanning mode or allow for reflecting the second light coming from the second mirror in the sheetfed scanning mode. Due to the special design, the overall volume of the scanning module is reduced.

    Abstract: An image reading apparatus for generating image data corresponding to a document image, includes: an irradiating section for irradiating light rays to an image bearing surface of a document; a housing formed with a slit for restrictedly passing light rays reflected from the image bearing surface of the document; a photoelectric conversion element for converting an optical image made of the light rays having passed through the slit of the housing to an electric signal; and an optical system for guiding the light rays having passed through the slit of the housing to the photoelectric conversion element. The housing has a light restrictor at each of the both ends of the slit. The light restrictor projects toward the image bearing surface of the document to thereby keep light rays reflected from an area outside a reading area of the image bearing surface of the document from entering the slit.
