Abstract:
In a frame 12 of an image sensor unit, a lens storage compartment 14 and a linear illuminator storage compartment 32 are adjacently arranged substantially in parallel to each other in the longitudinal direction with an inter-compartment portion 33 interposed therebetween, a pin insertion opening 21 that extends from the lens storage compartment 14 to an outside of the frame is formed, a vertical reference face 23 with which a rod lens array 9 is brought into close contact is formed on the inter-compartment portion 33, and a notch 15 that is used for applying an adhesive 13 is formed so as to be open from the lens storage compartment 14 to the linear illuminator storage compartment 32.
Abstract:
A scanning module includes a main body and a sensor module. The sensor module includes a circuit board, a sensing element, an image sensor adjustable mechanism and four adjustable rods. By means of the image sensor adjustable mechanism and these four adjustable rods, the positions of the sensing element can be controlled in seven degrees of freedom.
Abstract:
The invention relates to an image reading apparatus and includes: scanning unit including a light source; a focusing mirror which reflects light from the light source on a reflecting surface portion; and a mirror holder which fixes the focusing mirror on fixing portions formed at both ends of the mirror holder, wherein, when the scanning unit is moved to read image information, the focusing mirror is formed such that the fixing portion is smaller than the reflecting surface portion in at least one of strength and rigidity.
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:
A contact image sensor is provided including a housing, a slit plate a lens, one or two light sources and a light-receiving element array mounted on a light-receiving element array substrate. The housing contains the slit plate, the lens, the one or two light sources and the light-receiving element array substrate. The optical system of the contact image sensor is aligned and one or more depressions are formed on an end of the substrate for the alignment. Power to the one or two light sources is applied through one or more leads. Each of the one or more depressions is large enough so that each of the leads can be passed through the respective depressions.

Abstract:
An image reading apparatus comprises: a light source for irradiating light to a photographic photosensitive material; an image forming optical system for forming reflected or transmitted light emitted from a photosensitive film into an image; a film carrier having a shape correspomding to various types of photographic films to be loaded from the outside and supporting the photosensitive film; and an optical waveguide being replaceably attached to a predetermined reference attachment position and having a shape corresponding to the type of photographic film. Furthermore, there are provided a withdrawing mechanism for moving the optical waveguide from the reference attachment position in the case of an incorrect combination of the shape of the film carrier and the shape of the optical waveguide, and a detecting mechanism therefor.
Abstract:
A paper-separating plate is adapted for a paper-separating mechanism having a paper-separating roller. The paper-separating plate placed around a side of the paper-separating roller comprises a main body and a cushion. The main body has a surface and a plurality of grooves and the grooves are positioned on the surface. The cushion is positioned on the surface of the main body and covers the grooves. The cushion positioned over the partial grooves is elastically pressed onto the paper-separating roller. The grooves are linear and the direction of extending the linear grooves is substantially parallel with the axis of the paper-separating roller, the linear grooves neighboring one another or each other. Besides, the cushion is made of flexible material and the main body is made of rigid material.
Abstract:
The invention includes at least one mechanic adjusting device between the chassis of a scanner and the light base mounted with a light tube. The adjusting device is operated to adjust the position of the light tube to change the relative position with the document to be scanned. Thus, the purpose of adjusting the lightness accepted by the line to be scanned on the document to be scanned can be achieved.
Abstract:
The invention is a method and associated apparatus for mounting an optical subassembly of an optical reading device onto an image sensor subassembly of an optical reading device with use of solder as a bonding material. In accordance with the invention, solderable surfaces are formed on either or both an optical subassembly and an image sensor subassembly. For mounting of the optical subassembly onto the image sensor subassembly, an assembly station worker aligns optical and imaging elements by observing indicia corresponding to electrical signals generated by the image sensor under controlled conditions, and then, when alignment is established, solders the subassemblies at any interfaces that are defined by the solderable surfaces. The solderable surfaces of either or both the optical or image sensor assemblies may be made in irregular configurations having increased surface areas per unit three dimensional space relative to that of a smooth surface. In one embodiment, the solderable surfaces include a pin on one of the subassemblies and a hole on the remaining subassembly.
