Abstract: A height adjustment structure for an image-scanning device. The scanning device has a guiding rod, an optical system and a document panel. The guiding rod and the document panel are fixed relative to each other. The optical system includes a box body and an axial rod bearer that can slide along into the guiding rod. The height adjustment structure includes a first positioning section and a second positioning section. The first positioning section is attached to one side of the box body and the second positioning section is attached to one side the axial rod bearer that faces the first positioning section. The first positioning section and the second positioning section has hooking mechanism, screwing mechanism or teeth-meshing mechanism for fixing the box body relative to the axial rod bearer and hence setting the distance from the box body to the document panel.

Abstract: A sheet-fed scanning device includes a scanning module, a sheet-feeding module, a driving module, a calibration sheet moving module, and a calibration sheet. The sheet-feeding module transports a document across a scan region, in which the scanning module scans the document. The driving module drives the sheet-feeding module and the calibration sheet moving module. The calibration sheet is moved to the scan region before the document is transported, is gradually moved away from the scan region as the document is being transported so that the scanning module scans a plurality of scan lines on the calibration sheet for calibration, and is moved completely out of the scan region when the document reaches the scan region, such that the scanning module scans the document thereafter. The calibration sheet cannot be moved back to the scan region until the driving module reverses.

Abstract: Disclosed is an image reading apparatus for moving a document reading unit to a point below a document feeder that feeds documents, and emitting light from a light source of the document reading unit toward a feed roller of the document feeder, whereby light reflected from a document that travels between the feed roller and the light source is sensed by the document feeding unit to thereby read an image on the document. The apparatus includes a photoelectronic converter for outputting an electric signal that conforms to amount of incident light, and a reading position setting unit for moving the document reading unit, irradiating the feed roller with light from the light source at each position to which the document reading unit is moved, causing the photoelectronic converter to output an electric signal that conforms to amount of light reflected from the feed roller at each position, detecting a range in a sub-scan direction over which this electric signal exceeds a predetermined threshold value, and setting a position at the center of this range as a reading position.

A second photoelectric conversion element array 201 reads an image of the transparent original based on the transmitted light collected by the second rod lens array 202. The first photoelectric conversion element array 14 is mounted on a first substrate 16. The second photoelectric conversion element array 201 is mounted on a second substrate 203. The first substrate 16 and the second substrate 203 are disposed separately, and the first photoelectric conversion element array 14 and the second photoelectric conversion element array 201 are disposed on different planes.

Abstract: Methods and systems for calibrating and aligning Time Delay Integration (TDI) Charge Coupled Device (CCD) sensors. A TDI sensor for linear imaging (line sensor) is calibrated by generating a two dimensional image from the line sensor, analyzing the two dimensional image, and calibrating the line sensor based on the analysis. An alignment correction can then be generated, the correction applied to the line sensor placement and the line sensor re-tested. A calibration system includes means for generating a two dimensional image from the TDI line sensor, means for analyzing the two dimensional image, and means for calibrating the line sensor based on the analysis of the two dimensional image.

Abstract: The invention includes at least one swingable elastic locking bar mounted on the chassis of the scanner, and the end of the elastic locking bar is provided with a contact member having a low friction coefficient, and let the contact member on the elastic locking bar contact the top cover of the frame body of the scanner. Thus, the chassis may be rigidly rested on the top cover or on the glass mounted on the top cover to move, thereby providing a good scanning effect of an arbitrary angle. The swingable action of the elastic locking bar may efficiently absorb the tolerance produced during fabrication and assembly of the top cover and the bottom housing of the frame body of the scanner, thereby assuring stability of the optical travel path.

Abstract: A digital scanner includes a multipurpose registration member that has a document registration edge locate surface, a carriage horizontal locate surface, a carriage vertical locate surface, and a platen locate surface. The platen locate surface provides registration for a transparent platen and the document registration edge locate surface provides registration for a registration edge member. The carriage horizontal locate surface and the carriage vertical locate surface provides registration for a scanning carriage which abuts the slide pad. Also, the multipurpose registration member includes a document handle locate surface to registration a document handler. The inclusion of these locate surfaces on a single registration member enables efficient assembly, without extraneous manual adjustments, of a digital scanner having proper registration.

Abstract: A hand scanner support and paper guide apparatus is disclosed for mechanically scanning a thin sheet, e.g. a sheet of paper, using a scanner designed to be hand-held. The apparatus includes a housing which includes a planar upper wall which serves as a flat surface along which the thin sheet is moved. A support assembly is connected to the housing and supports the scanner a spaced distance above the planar upper wall as the thin sheet is moved past the scanner. A guide assembly is connected to the housing and guides the thin sheet in a straight path as the thin sheet is moved along the planar upper wall. A drive assembly is housed within the housing and moved the thin sheet past the scanner. The drive assembly includes a driven, thin-sheet-contacting element such as a cylindrical roller; and a slot, in the planar upper wall, permits the cylindrical roller to contact and move the thin sheet as it lies on the planar upper wall. The scanner support assembly includes a first support element which supports the scanner from below the scanner; and the scanner support assembly also includes a second support element which supports the scanner from above the scanner. The first support element may be a U-shaped bar that extends across the planar upper wall in spaced relation thereto. The second support element may be a flexible strap.
