Abstract:
A compact, low-cost photographic film scanner 10 particularly adapted to scanning Advance Photo System (APS) film includes an imaging assembly having an elongated L-shaped housing with a photosensor, for example, a CCD 66, mounted directly to one end of the housing, the other end having a scanning aperture and film rails 84 integrally formed on the housing, the film rails 84 defining a film plane 86 over the scanning aperture. The housing comprises a two piece snap together configuration that provides support for the focusing lens 77 as well the photosensor and film scan gate. Additionally, the housing includes support arms 120 that receive and lock in place an LED illuminant head assembly 200. The imaging apparatus housing 70 conveniently snap locks into place on the scanner chassis in an opening formed in the film drive path 38.
Abstract:
A document scanner carriage (20) housing contains a pair of spaced mirrors (34,36) whose spacing and parallelism is precisely maintained by floating metal spacer plates (60,62) which are not affixed to the housing. Spaced springs (35) urge one of the mirrors (34,36) into engagement with the spacer plates (60,62), the other mirror(34,36) being referenced to the molded plastic housing (50). The parallel facing image plane sides of the mirrors (34,36) are substantially unobstructed by the spacer plates (60,62) which contact them thus allowing the scanner (10) to efficiently use a substantial proportion of the image planes of the mirrors (34,36) and occupy a comparatively small footprint. The floating spacer plates (60,62) and mirrors (34,36) are cushioned against shock and vibration by compressed elastomeric pads (80,81,82,83) on the underside of the housing cover (30) which allows the spacing and parallelism of the mirrors (34,36) to be maintained without direct affixation of the mirrors (34,36) or spacer plates (60,62) to the housing (50).
Abstract:
A scanning head comprises a support member (2) for supporting the head in pressing contact with a platen (26). The support member has lower strength portions (A) spaced longitudinally of the head, and higher strength portions (B) alternate with the lower strength portions. The support member is easily bendable at the lower strength portions, and the higher strength portions are urged by springs (27) toward the platen. Thus, the head can come into intimate pressing contact with the platen even if the surface flatness of the support member as a whole is not strictly realized.
Abstract:
A modular image sensor array is disclosed which includes a plurality of tiles each of which has an image sensor mounted thereon. The tiles are mounted on a base plate such that the image sensors form a predetermined pattern. In order to precisely locate the tiles relative to each other and to provide for the replacement of defective tiles, the tiles are assembled in an interlocking pattern on the base plate. The top surface of the tiles is formed by ceramic plates, and electrical conductors for the image sensors are formed on one of the ceramic plates. A transparent cover is mounted over all of the image sensors in the array.

A solid-state image pickup device comprising: a multilayer wiring board 2 having an opening portion 21; a spacer 3 covered with a conductive film 32, and fixed to the multilayer wiring board 2 in a state of making the conductive film 32 face contact with a reference potential electrode exposed into the opening portion 21 of the multilayer wiring board 2; a solid-state image pickup element 4 fixed to the spacer 3 in a state of face contact with the conductive film 32 of the spacer 3, and arranged in the opening portion 21; and an optical element 5 fixed at a position opposing the solid-state image pickup element 4 via the spacer 3, and transmitting light into the opening portion.
Abstract:
An image reading device is provided that comprises: concave first lens mirrors (7) that are arranged in an array shape along a main scanning direction and that are adapted to collimate scattered light reflected by an irradiated object (1) and are adapted to reflect the scattered light as a substantially parallel bundle of rays that are angled in a sub-scanning direction; planar mirrors (8) that are adapted to reflect light from the first lens mirrors (7); apertures (9) that are arranged in an array shape and that allow light from the planar mirrors (8) to pass through by way of openings (10) that are arranged in an array shape and that are light-shielded therearound for selectively allowing light to pass through; concave second lens mirrors (11) that are arranged in an array shape into which light from the apertures (9) is incident and that are adapted to reflect the light from the apertures as converged light; and light receivers that have light receiving areas on which light from the second lens mirrors (11) is incident and that are adapted toform images that correspond to light from the openings.
Abstract:
An illuminating apparatus includes a columnar light guide (1, 2), a board (11, 12) having a light source (3, 4, 5, 6) fastened on one surface thereof, and a holder (7, 8). The holder is formed with a through-hole (7a, 7b, 8a, 8b) into which an end of the light guide (1, 2) in the columnar center axis direction is fitted to hold the light guide (1, 2), and a catch (7c, 7d, 8c, 8d) that catches and holds the board (11, 12) with the light source (3, 4, 5, 6) facing the end surface of the light guide (1, 2) in the columnar center axis direction in the through-hole (7a, 7b, 8a, 8b).

Abstract:
A contact-type image sensor (20) comprises a case (21), a glass cover (22) provided on an upper surface of the case (21), a bottom substrate (23) mounted in a bottom surface of the case (21), light receiving elements (24) mounted on the bottom substrate, light emitting elements (25) for irradiating an object (D) on the glass cover (22) with light, and a rod lens array (27) for collecting the light reflected by the object (D) on the glass cover (22) onto the light receiving elements (24). The light emitting elements (25) are mounted on the bottom substrate (23). The contact-type image sensor further comprises a light guide (26) provided in the case (21) for efficiently directing the light from the light emitting elements (25) to a predetermined region (L) of the glass cover (22). The case (21) is formed with a holding groove (29) for receiving the rod lenses array (27) from above, and the light guide (26) has ends each formed with a tab (37) for pressing the rod lens array (26) from above.
