Abstract:
A lens unit (U15) includes a housing (45), an upper and a lower lens arrays (A1null, A2null), and a first and a second prisms (4A, 4B). Each of the lens arrays includes a plurality of lenses, a light-shielding member (4), and a plurality of positioning projections, all of which are integral with each other. Downwardly traveling light which enters the housing (45) through a first slit (45c) formed at an upper portion of the housing (45) is directed upward by the first prism (4A) to pass through the two lens arrays (A1null, A2null). The light is then directed downward by the second prism (4B) to exit the housing through a second slit (45d) formed at a lower portion of the housing (45).
Abstract:
A thermal printer includes a thermal printhead, a transfer assembly, and a controller. The thermal printhead has an array of heating regions arranged in a primary scanning direction, and a driver for selectively heating the heating regions. The transfer assembly feeds a recording paper in facing relationship to the array of heating regions in a secondary scanning direction perpendicular to the primary scanning direction. The controller is combined with the driver for causing each of the heating regions to selectively form, on the recording paper, differently sized print dots which include an off-dot, a maximum-size dot, and at least one intermediate-size dot.
Abstract:
An image forming apparatus (X) includes a print head (2) provided with a projection (23a) which is offset with respect to a lens (22a) in an secondary scanning direction (CD) and which protrudes beyond the lens (22a) toward the photosensitive recording medium (4) for abutting against the photosensitive recording medium (4). The projection (23a) moving in contact with the photosensitive recording medium (4) during exposure corrects waviness of the photosensitive recording medium (4).
Abstract:
An image sensor module includes a holder and a lens unit attached in the holder. The lens unit is held in the holder by at least one engagement projection formed by plastically deforming a part of the holder. Preferably, the lens unit includes a first lens spaced from the engagement projection and a second lens adjoining the engagement projection. Each of the first lens and the second lens includes a central lens portion, and a flat peripheral portion surrounding the lens portion. The flat peripheral portion of the first lens is held in contact with the flat peripheral portion of the second lens. The engagement projection engages the flat peripheral portion of the second lens.
Abstract:
A liquid crystal display device includes a first and a second substrates (1, 2) disposed in parallel to each other, a liquid crystal layer (3) disposed between the two substrates (1, 2) and filled with liquid crystal, and a reflective electrode (13) having a reflective surface (13a) on which light rays coming from the outside through the first substrate (1) and the liquid crystal layer (3) are reflected towards the first substrate (1). The reflective surface (13a) of the reflective electrode (13) is undulated. The reflective surface (13a) of the reflective electrode (13) is provided with an alignment film (14B) for twisting liquid crystal molecules contained in the liquid crystal layer (3). The height of the undulation on the reflective surface (13a) of the reflective electrode (13) is smaller than at least the thickness of the alignment film (14B) at a concave portion of the undulated reflective surface (13a).
Abstract:
A liquid crystal display includes a liquid crystal layer, a holding assembly for internally holding the liquid crystal layer, and a diffusion mollifying layer that reduces the diffusion of light entering into the assembly. The holding assembly includes a plate having a rugged surface resulting from a surface-roughening process. The rugged surface is covered by the diffusion mollifying layer to reduce the frequency of light diffusion.
Abstract:
The present invention relates to a print head (3) including an illuminator (5) for emitting light in a line extending in a primary scanning direction, a liquid crystal shutter (6) for selecting whether or not light traveling from the illuminator (5) is allowed to pass, and a light emitting portion (323) for emitting light traveling from the liquid crystal shutter (6) toward a photosensitive recording medium (22). The liquid crystal shutter (6) includes a plurality of individual shutter portions aligned in the primary scanning direction, for example. Preferably, each of the shutter portions is capable of individually selecting whether or not the light traveling from the illuminator (5) is allowed to pass.
Abstract:
A liquid crystal display device includes a first substrate (1) and a second substrate (2) disposed in parallel to each other, a liquid crystal layer (3) disposed between the two substrates (1, 2) and filled with liquid crystal, and an ink retaining layer (7) disposed on a surface (1b) of the first substrate (1) facing the second substrate (2). A surface of the ink retaining layer (7) is provided with plural filter strips (7R, 7G, 7B) each retaining a respective color ink, and each of the filter strips (7R, 7G, 7B) includes plural columns and plural rows of generally circular dots (24) arranged in a strip or rectangle, each of them being provided by a color ink droplet.
Abstract:
An image reading apparatus includes a light source for illuminating an image reading region extending in the primary scanning direction, and a plurality of lenses for focusing light reflected on the image reading region and for producing reduced images. Each of the lenses has an optical axis which intersects a predetermined portion of the image reading region. The image reading apparatus further includes a plurality of light receiving elements for output of image signals based on the light focused by the lenses and a light conductor for leading the light emitted by the light source toward the image reading region. The light conductor leads the emitted light so that the predetermined portion of the image reading region is illuminated more brightly than the adjacent portions.
Abstract:
An image sensor module (S) includes a substrate (4) having a projecting portion (41) projecting sideways from a frame (3). The projecting portion (41) has an end (4b) provided with a plurality of terminals (81) electrically connected to an image sensor chip (5). The image sensor module (X) can be easily connected to another apparatus by inserting the end (4b) of the projecting portion (41) into a socket type connector.
