Abstract: An image input apparatus for an image scanning reading apparatus comprises a cylindrical holder for holding a plurality of originals and reference portions for calibration serving as references in reading original, a scanning head for scanning the original holder, and a memory for storing positions of the reference portions for calibration. The position of the reference portion for calibration is stored prior to the reading of the original, and when the scanning is started, the scanning head is moved to the stored position, the reference data for calibration is read by the scanning head at that position, and the corresponding original is read based on the data.

Abstract: A two-sided scanning device includes a first image scanning module, a second image scanning module, a first scanning background component, a first brightness calibration component, a second scanning background component, and a second brightness calibration component. When the second image scanning module moves relative to the first image scanning module to a scanning position, the second image scanning module drives the first scanning background component to move relative to the first image scanning module, so that the first image scanning module and the second image scanning module are aligned with the first scanning background component and the second scanning background component, respectively. Therefore, the first scanning background component and the second scanning background component can be scanning backgrounds for the first image scanning module and the second image scanning module to generate a scanning image of an object with a size corresponding to an actual size of the object.

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: A carriage motor which is a heat generating device is arranged next to a CIS in a scanner unit. The carriage motor drives respective transport rollers of an ADF unit via a gear system as well. The scanner unit makes a white reference board be read so as to obtain white reference data, and obtains black reference data more frequently than the white reference data, e.g., in a continuous process for reading a document. As a CIS module continues a reading process, the black reference data changes as being affected by a change in temperature in the CIS module, etc. The scanner unit deals with such a change in the black reference data by obtaining the black reference data more frequently.

Abstract: An image reading apparatus includes a reading unit having a reading surface and being rotatable about an axis of rotation, and a facing member that comes into contact with the reading unit and faces the reading surface when the reading unit is at a reading position. The reading unit is capable of reading a portion of an object that faces the reading surface when the reading unit is at the reading position. When the reading unit is at a position other than the reading position, the reading surface is positioned nearer to the axis of rotation than when the reading unit is at the reading position and the reading unit is spaced apart from the facing member.
