摘要： In a method for reading a document set on a document positioning plate to output image data, an edge area of an image of an entire reading area is extracted to form a first rectangle area including the extracted edge area. If a position of an apex of the first rectangle area farthest from a reading reference position and a size of the first rectangle area satisfy predetermined conditions, image data corresponding to a second rectangle area including the first rectangle area and the reading reference position are output.

摘要： An image reader includes a lamp that irradiates light onto a document, a first carriage that moves the lamp along the document to optically scan the document, a CCD that receives light reflected from the document and prepares an image data indicative of an image of the document. A size sensor detects a length of the document in an auxiliary scanning direction, and an IPU that detects a length of the document in the main scanning direction from the image data. A CPU monitors whether a size of the document has changed, based on the detected by the size sensor, and controls irradiation of the light by the lamp based on the result of monitoring.

摘要： In an image reader, a reading member fixedly mounted in the image reader reads an image on a sheet conveyed into the image reader. A guide is disposed opposite the reading member to support the sheet with respect to the reading member. A guide moving member moves the guide with respect to the reading member in a main scanning direction in which the reading member reads the image on the sheet. A guide rotating member rotates the guide in a sub-scanning direction perpendicular to the main scanning direction. A controller controls the reading member to scan different positions on the guide moved by the guide moving member and rotated by the guide rotating member to generate shading data.
