摘要:
A lens array unit includes first and second lens arrays cooperative with each other. The first lens array is provided with a plurality of first convex lenses and a first transparent holder formed integral with the first lenses. Each of the first lenses has first and second lens surfaces. The second lens array is provided with a plurality of second convex lenses and a second transparent holder formed integral with the second lenses Each of the second lenses has third and fourth lens surfaces. The second lens array is attached to the first lens array so that the third lens surfaces face the second lens surfaces. The lens array unit further includes a light shield mounted on the first lens array. The light shield is formed with a plurality of through-holes each facing the relevant one of the first lens surfaces.

A plurality of first contact holes reaching an n+-type semiconductor area used as the source of a MISFET employed in a logic-DRAM mixture LSI and a plurality of second contact holes reaching another n+-type semiconductor area used as the drain of the MISFET are bored through an insulation layer created over a gate electrode of the MISFET. A conductive film on the same layer as a bit line shunts the n+-type semiconductor area used as the source through the first contact holes. Another conductive film shunts the n+-type semiconductor area used as the drain through the second contact holes.
摘要:
A lens array is provided with a plurality of lenses and a holder formed integral with the lenses. Each of the lenses includes a non-flat first lens surface and a flat second lens surface. The holder includes a first surface adjacent to the first lens surface and a second surface adjacent to the second lens surface. The second surface is formed with a plurality of recesses in each of which a light shielding layer is provided.

An image read/write head (A) includes: a substrate (4) having a first widthwise side portion (4c), a second widthwise side portion (4d), and an upper surface carrying a row of light-receiving elements (2) longitudinally of the substrate; an elongate case (1) mounted to the upper surface of the substrate (4) to enclose the light-receiving elements (2); a transparent cover (19) mounted to an upper surface of the case (1) for contact with a document to be fed; a light source (3) disposed in the case for illuminating the document; a lens (5) disposed in the case for causing an image of the document (D) illuminated by the light source (3) to be formed on the light-receiving elements (2); and a row of printing elements (8) carried by the an upper surface of the substrate at an excess portion which is provided by extending the first side portion (4c) beyond a lower edge of the case (1) by a predetermined amount. The transparent cover (19) is inclined such that the cover (19) becomes progressively farther from the substrate as it extends toward the first side portion (4c) of the substrate (4).
摘要:
An image reading apparatus is provided which includes a cold-cathode tube as a light source for illuminating a document sheet, an inverter for providing the light source with driving power. A connection cable is used for electrically connecting the light source to the inverter. The image reading apparatus also includes three kinds of rows of light receiving elements arranged in the primary scanning direction for detecting the light reflected on the document sheet. A lens array is provided for focusing the reflected light at the respective rows of light receiving elements. The light receiving elements are mounted on a printed circuit board. The light source, the inverter, the lens array and the printed circuit board are supported by a single case of the image reading apparatus.

An image reading apparatus is provided which includes light source for irradiating a document sheet with light, an elongated light-leading member through which light emitted from the light source propagates. The light-leading member is provided with a head surface, a bottom surface, a first side surface and a second side surface. The image reading apparatus further includes a row of image sensor chips for detecting light reflected on the document sheet, and an insulating circuit board for carrying the image sensor chips. The light source is also mounted on the circuit board. The cross section of the light-leading member is pentagonal, parabolic, or elliptic.

An image reading apparatus includes a light source for irradiating a document sheet with light, a row of red light receiving elements arranged in a primary scanning direction for detecting a red component of the light reflected on the document sheet, a row of green light receiving elements arranged in the primary scanning direction for detecting a green component of the reflected light, and a row of blue light receiving elements arranged in the primary scanning direction for detecting a blue component of the reflected light. The row of red light receiving elements, the row of green light receiving elements and the row of blue light receiving elements are displaced from each other in a secondary scanning direction which is perpendicular to the primary scanning direction.
