Abstract: An image scanner includes a transparent plate, a scanning device, a driving device, a positioning member, a light absorbing portion and a white reference portion. The transparent plate has an original placing surface. The scanning device irradiates an original with light by means of a light source and scans reflected light from the original. The driving device reciprocates the scanning device along the transparent plate. The positioning member positions the original placed on the original placing surface of the transparent plate. The light absorbing portion, which is disposed on the original placing surface side of the positioning member and at substantially a central portion of the positioning member in moving directions of the scanning device, absorbs ambient light entering to the original placing surface side of the positioning member through the transparent plate. The white reference portion is provided to the original placing surface side of the positioning member.

Abstract: An image reader includes an image reading device, which is capable of reading a document, an initialization operation control device, which performs an initialization operation before a reading operation starts, in order to return the image reading device to a standby position where the image reading device needs to be located until the reading operation starts, an storage device that stores flag data representing whether the initialization operation needs to be performed, and a flag data control device that controls the flag data. When the flag data represents necessity of execution of the initialization operation, the initialization operation control device performs the initialization operation. When the flag data represents normecessity of the execution of the initialization operation, the initialization operation control device does not perform the initialization operation.

Abstract: A scanner includes a scan bar, a first scan-bar homing reference, a second scan-bar homing reference and an image placement area. The scan bar is movable along a subscan axis. The second scan-bar homing reference is spaced apart along the subscan axis from the first scan-bar homing reference. The image placement area is located between the first and second scan-bar homing references. A broad method uses the scanner. One step includes performing a prescan or an image scan of an image by moving the scan bar along the subscan axis from the first scan-bar homing reference in relation to the image. Another step includes performing a prescan or an image scan of the image or of an additional image by moving the scan bar along the subscan axis from the second scan-bar homing reference in relation to the image or the additional image.

Abstract: An image reading method and apparatus. A reader is mounted and reads one side of an original document being conveyed at a reading position. A contact glass includes a surface contacting the original document. A reference is disposed at a side of the contact glass opposite to the surface and movable between the reading position and a standby position. The reference includes a surface facing the reader which has a predetermined color for providing shading data used for a shading correction. A carrier moves the reference to the reading position. The reader obtains the shading data by reading the predetermined color on the surface of the reference at the reading position.

Abstract: The image reader according to the present invention is able to set the accurate threshold level free of influence of dirt and dust even when the reference “white” level is requested for shading correction during the acceleration while the carriage is being accelerated without increasing the averaging frequency when the reflected light from the white board is read for shading correction. In addition, because the distance between the head end of the transparent glass and the home position as well as the distance between the home position and the reading window are shortened, the size of the image reader is reduced.

Abstract: A scanning method that saves time by reducing calculations performed in a scanner. The scanner has a housing, a transparent platform installed on the housing, a document positioned on the transparent platform, a scanning module, a calibration paper, a memory, and a processor. If an effective image range has been determined within a predetermined amount of time after the scanner is turned on, the effective image range will not be redefined before scanning the document.

Abstract: A calibration mechanism for an optical module of a sheet-fed scanner is disclosed. The calibration mechanism includes a calibration strip and a driving unit. The calibration strip is moved by the driving unit, and the calibration strip may be moved relative to the optical module for calibrating color depth. The driving unit includes a roller and a flexible strip. One end of the flexible strip is mounted to the roller, and the calibration strip is mounted or formed on the flexible strip. The flexible strip is moved by the roller action so that the calibration strip is moved relative to the optical module, and the optical module may accordingly calibrate the color depth.
