Abstract: When a transport section transports be a media, a controller of an image reading apparatus determines the lengths of the media in the transport direction, based on detection results of a medium detector. When determining that a length of a medium is equal to or more than a threshold and then determining that a length of a subsequent medium is equal to or more than the threshold, the controller decreases an ejection speed of the subsequent medium to a second speed by the transport section. When determining that a length of a medium is equal to or more than the threshold and then determining that a length of a subsequent medium is less than the threshold, the controller decreases the ejection speed from the first speed to a third speed that is lower than the second speed by the transport section.

The processing unit determines whether or not the inclination error has occurred in accordance with a document size and a tilt angle of the document.

Abstract: In a continuous mode, when a state in which a current value, which is output of a load detecting sensor, is equal to or more than a predetermined threshold (a current value) continues for a predetermined threshold (the number of times), it is determined that transportation is abnormal. In a cumulative mode, when the total number of times by which the current value, which is the output of the load detecting sensor, is equal to or more than the predetermined threshold (the current value) is equal to or more than a predetermined threshold, it is determined that the transportation is abnormal. A controller sets a detection mode of a first medium to the continuous mode, and sets a detection mode of a second medium to the cumulative mode.
