Abstract
In an image reading apparatus, in a first process, first and second motor rotate feed and conveyance rollers with circumferential speeds of first and second speeds, respectively. In the first process, the reverse roller has a first separation performance for separating a sheet from another sheet. In a second process, after a detector detects a leading edge of the sheet, the controller stops the first motor, and decelerates the second motor, and the reverse roller has a second separation performance lower than the first separation performance. In a third process, after a trailing edge of the sheet reaches a specific position, the first motor starts rotating the feed roller with the circumferential speed of the first speed. In a fourth process, after the trailing edge of the sheet passes through a reading end position, the controller accelerates the second motor.
