Abstract:
A contact-type linear image sensor has two separate substrates (l2, l4) aligned adjacent to each other A linear array (D) of amorphous silicon photoelectric converting elements serving as photoelectric cells and a matrix wiring unit (28) are provided on a first substrate (l2) Driver IC chips (34, 36) are mounted on a second substrate (l4) Connection pad patterns (20a) for common cell electrodes (20) of cell groups (Dl, D2,..., Dm) and connection pad patterns (32a, 32b, 32c, 32d) for row signal lines (26) of the matrix wiring unit (28) are provided concentrically at a peripheral edge of the first substrate (l2) to be alinged along a junction edge line defined between the substrates (l2, l4). Connection pad patterns (38) for the IC chips (34, 36) are linearly aligned at a peripheral edge of the second substrate (l4) and along the substrate junction edge line to oppose the pad patterns (20a, 32a, 32b, 32c, 32d) of the first substrate (l2). A connector unit for electrically connecting the pad patterns of the first and second substrates (l2, l4) may be provided at only one position of the junction edge portion of the first and second substrates (l2, l4).
Abstract:
In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.
Abstract:
An image forming apparatus for forming images to a medium, includes an apparatus housing; a temperature detection unit for detecting a temperature of a surrounding of the apparatus housing; a dehumidifying unit for dehumidifying an interior surrounded by the apparatus housing; and a dehumidifying decision unit for operating the dehumidifying unit based on a change of the detected temperature at the temperature detection unit, to certainly remove dew condensation
Abstract:
A dual-slope light guide includes a first surface, a second surface and a curved surface. The first surface has first reflecting structures. The second surface, connected to the first surface, has second reflecting structures. An included angle between the first surface and the second surface is unequal to 180 degrees. The curved surface connects the first surface to the second surface. The first surface, the second surface and the curved surface extend from a first end of the light guide to a second end of the light guide. A light beam incident to the first end of the light guide is reflected and converted by the first reflecting structure and the second reflecting structure into linear light emitted from the curved surface. A light source module and an optical assembly for a scanner are also disclosed.
Abstract:
An overhead scanner 1 includes an imaging unit 22 that images a medium S placed on a mount surface 2 to be read from above and a light source 21 that is arranged to be able to irradiate the medium S with light during imaging by the imaging unit 22. A control device 40 of the overhead scanner 1 performs anti-glare control when detecting that the medium S is glossy. This prevents glare from occurring to the user during operation of the overhead scanner 1.
Abstract:
An image reading apparatus, including: an image reading unit configured to read an image of a document placed on a document placing portion; a document pressure unit configured to press the document placed on the document placing portion against the document placing portion; a first holding unit configured to hold the document pressure unit so that the document pressure unit is openable and closable with respect to the document placing portion with a shaft pivotally supporting the document pressure unit; and a second holding unit configured to hold the document pressure unit so that the document pressure unit is openable and closable with respect to the document placing portion without a shaft pivotally supporting the document pressure unit.
Abstract:
An illumination apparatus includes: a rod-like light guide member that directs light emitted from a first light source and a second light source from an emission surface to an illuminated body while propagating the light by reflection surfaces; and a light blocking member including a second surrounding portion slidably covering another end of the light guide member, wherein the second surrounding portion includes: a light blocking portion protruding toward one end of the light guide member and covering the emission surface of the light guide member; and a cut-out portion adjacent to the light blocking portion and exposing the reflection surface of the light guide member.
