Abstract:
A lens array unit (U1) comprising first and second lens arrays (1, 2), the first and second lens arrays (1, 2) having a plurality of convex lenses (11, 21) capable of forming erect, full-size images. The lens arrays are formed by integrally molding a plurality of lenses (11, 21) and supports (10, 20) for supporting these lenses by a transparent resin, whereby the lens arrays can be produced easily.
Abstract:
An apparatus for scanning a document, including scanning a photograph, the apparatus including a contact image sensor (CIS), the apparatus designed to reduce the friction between the contact image sensor and the document being scanned. The reduction is achieved by reducing the friction by use of a non-stick material or by reducing the static electricity forces or both. The preferred embodiment is a CIS whose housing is made of a non-stick material which also is static electricity dissipative.
Abstract:
This invention has as its object to provide an image sensor which can effectively attain higher read resolution, and an image processing apparatus and information processing system using the same. To achieve this object, function members including a light source (6) for irradiating an object to be read (PP) with light, a sensor (3) for receiving light reflected by the object to be read (PP), and an imaging element (7) for forming an image of the reflected light on a light-receiving portion of the sensor (3) are attached to and supported by a support member (1) to have a predetermined positional relationship. In order to assure high attachment positional precision and rigidity for the function members, the support member (1) is formed to have a hollow shape. The support member (1) is formed to have the hollow shape along its longitudinal direction. Two side portions of the support member (1) are formed to have a hollow shape, and are coupled at end portions in the longitudinal direction.

Abstract:
An image sensor has a supporting member for integrally supporting a reading system including illuminating means for illuminating an original document, a photoelectrically converting means and imaging means for imaging light reflected by the surface of the original document onto the photoelectrically converting means, and has a member disposed on the side surface of the supporting member. The image sensor has two or more substantially independent spaces formed in the supporting member. The illuminating means, the imaging means and the photoelectrically converting means are accommodated in one of the spaces.
Abstract:
A hand-held scanning device 10 is disclosed in which the scanning device housing window 12 has a recessed optical portion 16, 18 of the window formed such that the recessed optical portion 16, 18 of the window 12 does not come into contact with the object 14 being scanned while a scan is being performed. This recessed optical portion 16, 18 of the window 12 eliminates damage caused by contact with the object 14 being scanned to the optical portion 16, 18 of the window 12. The recessed portion 16, 18 of the window 12 is formed without corners in such a manner that it may easily be wiped clean by the end user without dirt, dust and the like building up in corners of the recess. The recessed portion 16, 18 of the window 12 is also formed in such a manner as to maintain the object 14 in a relatively flat position under the scan window throughout the scanning process.
Abstract:
A high speed imaging apparatus for CCD based scanners comprises a housing having separate compartments which complement modular assemblies installed therein. A decoder compartment houses components associated with locating and decoding an image. An optics compartment houses the mirrors and associated optics for reflecting the subject image onto the CCD detector. A lighting compartment includes high intensity lamps and the associated components for illuminating an object to be imaged. The lighting compartment includes a heat management system which removes the heat from the high intensity lamps and prevents heat from migrating to other compartments within the housing.
