摘要： An image scan apparatus includes a scanner including: a document table on which a document is placed; a carriage which scans a read area of an image; a stepping motor which moves the carriage; an image processing unit which processes an image signal resulted from scanning by the carriage; a scanner controller which performs a process necessary to read the image; and memory which stores information, wherein on the document table, a sub-scan magnification adjustment chart which expresses a predetermined shape in order to calculate an actual sub-scan magnification by the scanner controller is placed. According to the image scan apparatus, when error occurs in the actual sub-scan magnification, the sub-scan magnification can be automatically adjusted without an operator performing the adjustment work of the magnification in the sub-scanning direction.

摘要： Where a magnification (enlargement/reduction of image) has been set through operation keys of an operation panel, a main CPU sends information on read magnification to a scanner CPU of a scanner section. In this case, where the magnification is not set in particular, information of 100% magnification is sent to the scanner CPU. Based on a microstep division number of a step angle corresponding to the received information on read magnification, the scanner CPU controls the driving of a scan motor via a scan motor driver.
