    Abstract: An optical scanning station is disclosed which utilizes light bending apparatus such as mirrors or optical wedges to gather and redirect some of the illumination radiating from the object. The gathering of the light occurs off-axis from the lens and the redirection of the light to the lens causes an off-axis angle between the light beam and the lens axis, thereby resulting in multiple images which are spaced apart from each other when focused on an image plane. The multiple images may be split apart and directed to separate image planes by use of front surface mirrors making the images then available for individual capture by charge couple devices or other similar image capture apparatus. Alternatively, the outboard images may be redirected, again by mirrors, to be focused coincident to the on-axis image, thereby increasing the illumination level at the image plane well in excess of that obtainable with only a single image of the object being focused at the image plane. The primary advantage of these devices is either to permit separate images to be presented on separate image planes without the subtractive losses occasioned by use of subtractive beam splitters or to combine the multiple images to raise the illumination level of a single image at the image plane, thereby permitting the use of slower lenses or reduced illumination level at the object.

    Abstract: An image reading device, such as may be employed in a facsmile transmitter, laser beam printer, copying machine, or the like, in which assembly and alignment of optical components of the system is simplified and stray light is prevented from reaching a photoelectric conversion element. The optical system and the photoelectric conversion element are fixedly secured to a single supporting frame in a desired predetermined positional relationship. The supporting frame is detachably mounted on a mounting surface of an image reading device body. The optical system includes a filter or dust-proof transparent cover, an optical path changing mirror, and an image forming lens, all of which are secured to the supporting frame. A light-quantity-distribution correcting light-shielding plate may be provided in front of the image forming lens to provide an even distribution of image light on the photoelectric conversion element.

    Abstract: Two aperture members are disposed on each side of a lens array. In one aperture member, decreasingly tapered through holes having a cross sectional area that gradually decreases in a light incident direction and increasingly tapered through holes having a cross sectional area that gradually increases in the light incident direction are alternatively arranged. The other aperture member that is oppositely disposed with respect to the lens array has the same configuration. The center axes of the decreasingly tapered through holes and the center axes of the increasingly tapered through holes are coincident with each other. This enables to achieve an image forming optical element that has a large amount of light and less irregularity of the amount of light.

    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.
