Abstract
An image reading apparatus includes a transport section configured to transport at least one sheet of paper along a transport path; a sonic wave detection section including a sonic wave transmitter and a sonic wave receiver that are disposed at positions between which the transport path is interposed, the sonic wave detection section being configured to output an output signal having a value that varies in accordance with a reception intensity with which the sonic wave receiver has received a sonic wave transmitted from the sonic wave transmitter; and a controller configured to determine a possibility of an occurrence of multi-feeding based on a result of comparing an output signal by the sonic wave detection section and two threshold value.
