    Abstract: A light guide unit (20) includes, a first light guide (21) having a column shape that takes a light incident upon one end surface and emits a light from other end surface and from a light emitter on a side surface of the first light guide (21), and a second light guide (22) having a column shape that takes the light emitted from the other end surface of the first light guide (21) then incident upon one end surface of the second light guide (22), and emits the light from a light emitter on a side surface of the second light guide (22), and the one end surface of the second light guide (22) are located close proximity to the other end surface of the first light guide (21). The first light guide (21) includes a first mating member (28A), and the second light guide (22) includes a second mating member (28B) engaging with a first alignment member such that the side surface of the first light guide (21) having the light emitter and the side surface of the second light guide (22) having the light emitter are flush with each other, and the other end surface of the first light guide (21) is located close proximity to the one end surface of the second light guide (22).

    Abstract: An optics module (150) for a scanning device (110) such as a portable scanner includes an illumination source (160) and guide (162) that transmits light through an optical window (164) of the scanning device casing (122) before reflecting off of the object (114) to be scanned. The reflected light from the object travels back through the optical window (164, 364) and a lens (166) before reaching a photosensor (168) for evaluation by an associated microprocessor (158). The optical window (164) of the scanning device (110) provides a recess (165, 365) in the scanning device casing (122). The recess (165, 365) of the window (164, 364) is formed using the functional components of the optics module (150) to eliminate a piece of glass typically used within the optical window that can be easily scratched or broken and provides a loss during the illumination process. By using the functional components of the optics module (150) to form the recessed optical window (165, 365), manufacturing costs to secure and replace a typical glass window contained therein can be eliminated, size of the optics module (150) is reduced, and any contaminates that gather around the optics module window (150) can be easily removed by the user.

    Abstract: In an image forming apparatus, an object surface (14) is disposed facing one end face of a rod lens array (10), while an image surface (16) is disposed facing the other end face thereof. A lens working distance of the rod lens array on the object side is substantially equal to that on the image side. An actual object-image distance Tco is set between the conjugate length TC1 at which the average value MTFave of the MTF of the rod lens array in the lens array direction is maximized and the conjugate length TC2 at which the ΔMTF (= (MTFmax - MTFmin)/MTFave) is minimized, and a shift quantity ΔC (= |TCo - TC1|) is set within 0mm
