Abstract

An image reading unit has a line sensor for reading a document and producing image data. A line counter counts the number of lines that are scanned during a period from a start of reading by the image reading unit until a time point when an edge of the document is read. A ROM stores, in advance, a corresponding relationship between error accumulation values and the numbers of lines. A control section reads out, from the ROM, an error accumulation value corresponding to the number of lines counted by the line counter, and determines the position of the edge of the document in the auxiliary scanning direction by subtracting the readout error accumulation value from a product of the counted number of lines and the auxiliary scanning pitch, thereby detecting a document length in the auxiliary scanning direction.
