    Abstract: An imager (50-1) for imaging a document (12) moving in a document track (14) in a table top document processing machine (10) includes a housing which is made of several portions which are designed to be assembled quickly with a minimum of fasteners. A first line of green LEDs (82-1) and a second line of red LEDs (82-2) are located in the housing to illuminate a scanning line (84) from which image data about the document is obtained by an optical system including a CCD device (100). The imager (50-1) is also designed so that it can be used on either side of the document track (14) to image the front or rear of the document. When two such imagers are used, a white reference member (198) located in one of the imagers is used by the other imager for calibrating the imager to ensure repeatable and uniform data.

    Abstract: A development device includes an imaging lens and light shielding walls. The imaging lens includes a body part having a constant diameter and both end parts arranged at both ends in an optical axial direction having diameters larger than the body part to capture a reflected light from a document onto an imaging part. The light shielding walls has a space with an interval larger than the diameter of the body part and smaller than the diameters of the both end parts, allowing the body part of the imaging lens to be arranged in the space, and shielding a light in the optical axial direction.

    Abstract: A scanning module capable of finely tuning the optical length comprises a lamp tube, a base, a photosensitive substrate, and an adjustment unit. The lamp tube provides a required light source for a document to be scanned. The base has a reflective mirror set and a camera lens. The reflective mirror set is used to receive light from the document, and transmits the light to the camera lens for focusing. The photosensitive substrate is used to convert light outputted by the camera lens into electronic signals. The adjustment unit is used to adjust the optical length between the base and the photosensitive substrate. The total optical length can thus be adjusted to correct the inaccuracy of magnification. Or the distance between the camera lens and the photosensitive substrate can be adjusted to align the focal length within the allowable inaccuracy of magnification to achieve an output image of better quality.
