Abstract: An object of this invention is to suppress a decrease in reading efficiency while preventing image degradation. To achieve this object, an image reading apparatus includes a light source which illuminates an object, a sensor which photoelectrically converts light reflected by the object and reads information on the object, a first density reference member which serves as a reference for correcting an image signal obtained by reading an original by the sensor, a second density reference member which is different from the first density reference member, a comparison unit which compares the second signal obtained by reading the second density reference member by the sensor and the third signal obtained by reading again the second density reference member by the sensor, and a correction unit which corrects the image signal on the basis of the first signal obtained by reading the first density reference member by the sensor, and the comparison result of the comparison device.

Abstract: An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.

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.

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: In a document scanner wherein a scanner bar can record images from either a platen or a document handler, a control system ensures that characteristics of the video from the scanner bar are consistent whether the images are recorded from the platen or the document handler. A calibration method includes passing a test sheet through the document handler and placing it on the platen, and then deriving a correction factor based on the resulting readings.

Abstract: A scanner comprises a transparent platen mounted on a housing, and an object-imaging device within the housing mounted for longitudinal movement relative to the platen and an object supported thereby. The object-imaging device is rotatable about a transverse axis and comprises an aperture for receiving light reflected from the object. The object-imaging device has a travel distance between a home end position and a back end position, the travel distance comprising a central portion and at least one end portion. The scanner further comprises a mechanism operatively associated with the object-imaging device for rotating the device about the transverse axis thereof in response to movement of the device within the at least one end portion of the travel distance, the device being rotated in a direction so that the light-receiving aperture is rotated away from the central portion of the travel distance.

Abstract: When a original document platform cover opening/closure detecting unit detects that an original document cover which covers a original document platform has been opened, an image original document has been set, and the original document cover has been closed, it outputs an original document cover closing signal. A preparing operation starting unit starts the operation of an image reading preparing unit after the original document cover closing signal is received. Each time the original document image is read, detected reflection light intensity is converted into image information without being influenced by disturbance light. A change in picture quality of an output image due to an ambient environmental change is prevented.
