    摘要: An image reading device includes a transporter transporting a document to a reading position, a first corrector correcting a skew of the document by coming into contact with a leading edge thereof, a radiating unit radiating light to the document, an image-information acquiring unit acquiring image information of the document based on information of light reflected therefrom, a reflector reflecting the radiated light, a leading-edge detector comparing a quantity of light reflected by the reflector with a quantity of light reflected by the document so as to detect the leading edge, a skew-amount calculator calculating a skew amount of the leading edge, and a second corrector correcting a skew of the image information based on the skew amount. The device switches between the skew correction by the first corrector and the skew correction by the second corrector based on document information, the skew amount, or user's selection.

    摘要: An image scanner is provided and includes a case having a document placement surface, two carriages which are mounted with optical components and move by running on rails, a wire drive mechanism for reciprocating the two carriages which are coupled to wires, and a movement restricting member for restricting a maximum movement distance of the first carriage in a stationary position mode to about 1.6 d or less, d being a groove depth of pulleys in mm and the maximum movement distance being a distance by which the first carriage is allowed to move in the read scanning direction in the stationary position mode in which the first carriage is kept stopped and fixed via the wires by moving the second carriage by causing the wire drive mechanism to operate so that the second carriage hits the fixedly disposed member to be stopped and fixed.
