Abstract: A digital copying device, which serves as an image reading apparatus for improving processing speed by adjusting the timing of various operations when reading is performed using a sheet-through system, causes a first traveling body to move beneath a white reference plate in order to read the white reference plate, and then performs an ADF shading operation to move the first traveling body beneath a sheet-through contact glass. The sheet-through contact glass is then subjected to a dirt detection operation by reading a dirt detection reference plate, whereupon an original is conveyed onto the sheet-through contact glass by an ADF to perform a sheet-through reading operation whereby an image of the original is read. When a sheet-through reading operation is to be performed, the sheet-through reading operation is started following the reception of an image reading request and after the elapse of a time (T=Ts+Tl−Td) obtained by subtracting a time Td, which extends from the beginning of the sheet-through reading operation to the point at which the tip of the original reaches a sheet-through reading position, from the sum of a time Ts required for the ADF shading operation and a time Tl required for the dirt detection operation.

Abstract: A selected section reading method of a flat-bed type multifunction product enables scanning of a desired selected section in the desired resolution by limiting the necessary selected section by inputting the horizontal and vertical direction coordinates through the operation panel after determining the horizontal and vertical coordinates for the scanning section from a ruler of the loading surface. Accordingly, there are the advantages in which a desired selected scanning section included in the total readable domain is able to be scanned in the actual resolution without moving the document or having to pre-scan the document, and the portion scanned in this manner may be magnified, reduced, processed for improved quality and photocopied and transmitted through a facsimile. In addition, the time wasted on reading portions that are needless to the user is saved, and the satisfaction level of user can be increased through the omission of inconvenient operations such as pre-scanning, re-scanning, editing/deleting and the like.

Abstract: An imaging system, which may be applied both to black and white and color imaging systems and comprising a platen member which defines an imaging portion and a calibration portion is disclosed. The imaging portion and the calibration portion comprise separate portions of the platen member. The platen member is supported by a movably mounted support member, and moves with the support member between a platen member calibrating position and a platen member imaging position. The platen member is dimensioned to support a sheet to be imaged. An imaging module with an imaging zone is supported in a position where the imaging zone is positioned to coincide with a portion of a sheet supported on the imaging portion of the platen member, when the platen member is in the platen member imaging position. A calibration member having a reference reflectivity is adhered to the calibration portion of the platen member. The imaging zone coincides with the calibration member, when the platen member is in the calibrating position. The calibration member lies substantially outside the imaging zone of the imaging module, when the platen member is in the platen member imaging position. A motor moves the support member between the calibrating position and the imaging position to allow performance of a calibration procedure on the imaging module.

Abstract: Disclosed is an image reading apparatus that can change the amounts of light of an exposure lamp at the time of reading a white reference value (shading correction value) and at the time of reading an image, or changing a signal amplification factor of an amplification section for amplifying the output of a CCD line sensor, by using a white-level correction value which has been read at the time of assembling and adjusting the apparatus. This can provide high-quality images without performing complex image processing even if an indicator is placed at such a location where a user is easy to see and use it.
