摘要： A document reading apparatus includes a document positioning plate configured to position a document, a carriage configured to move a light source along the document positioning plate, a reading unit configured to read an image of a document illuminated by a light source of the carriage, a white reference member provided in the displacement range of the carriage, an input unit configured to input a reading start instruction for a document, and a control unit configured to move the carriage along the document positioning plate in response to a reading start instruction input via the input unit. The control unit moves the carriage to a first position at which the white reference member is provided, cause the reading unit to read the white reference member, moves the carriage to a second position that is an acceleration start position for accelerating toward the reading start position of the document positioning plate, and waits for a reading start instruction input from the input unit.

摘要： In reading an image of a document in a monochromatic document reading mode, a document reading apparatus reads the image of the document while conveying the document at a speed determined according to a variable magnification ratio, executes digital variable magnification on the read multivalued image in a main scanning direction by using a main scanning direction variable magnification unit, binarizes the multivalued image, and stores the binary image on a memory. In reading an image in a color document reading mode, the document reading apparatus reads the image of the document while conveying the document at a predetermined speed, stores the read multivalued image on the memory, and executes digital variable magnification on the multivalued image in the main scanning direction and a sub scanning direction.
