    Abstract: The invention relates to a scanner's optical device, receive the light coming from the image of an object to be scanned, comprising: several reflective mirrors, a light-focusing module, and a charge coupled device. The reflective mirrors provide reflection and directional change for the light and, by appropriately arranging several reflective mirrors, the light of the object to be scanned directionally changed to a predetermined route. With at least one curving mirror, the light-focusing module focus the light of the predetermined route and then directionally change it, and a raster is then provided in the light route of the curving mirror for filtering out unnecessary light. The charge coupled device may receive the light coming from the light-focusing module and convert it into electronic signals. The said light-focusing module replaces the prior lens set for executing a scanning job.

    Abstract: An optical image reading device that has an adjustable amplification rate and a method for adjusting the same. The optical image reading device includes a transparent object being disposed within the object distance or the image distance. Since the refractive index of the transparent object is larger than that of the air, the compensation and shrinkage of the object or image distances can be achieved accurately without changing the position of the lens and the electro-optical sensor. The amplification rate of the optical image reading device is thus accurately adjusted.

    Abstract: An image reader for reading an image drawn on a paper or a sheet-like recording medium, an image processor provided with the image reader, such as a copying machine, a scanner and the like, and a fiber lens to be applied to those devices. The image processor has to be large in the whole size of device to read both sides of an original. Therefore, the image processor of the present invention comprises an image reader (10a) on the upper side of transport path and an image reader (10b) on the lower side of that respectively. In order to downsize the device, it is necessary to shorten the diameter of optical fiber (140) of the fiber lens (14) installed in the imager reader as light receiving means. In this case, the optical fiber (140) is provided with a light-absorbing layer 8 (143) around of the optical fiber (140) in order to restrain the crosstalk and the flare phenomenon. The illuminance of light source means (15) installed in the image reader gets smaller as the device is downsized. In case where the illuminance is small, the image quality is deteriorated by the floating of the original. Accordingly, the image reader should be provided with the light source means so as to uniform the illuminance over a specific width of the main and sub scanning directions. Therefore, it is possible to avoid the deterioration of the image quality.

For image stabilization in order to compensate for an undesirable wobbling movement of the imaging over the detector (14), the optical element is constituted of a micro-optical lens array (10).
