摘要：
A transport device includes a set section, a sheet sensor, and a feeding member. When a detection member does not retract, the sheet sensor outputs an OFF-detection signal. The feeding member is displaced between a feed position and a non-feed position on the basis of the detection signal. At the feed position, the feeding member comes in contact with the sheet set in the set section from above and feeds the sheet toward the downstream side on a transport path. At the non-feed position, the feeding member is separated upward from the feed position. A method, which detects a sheet in the transport device, includes displacing the feeding member from the non-feed position to the feed position, and detecting that the sheet does not exist in the set section when an OFF-detection signal is output from the sheet sensor while the feeding member is positioned at the feed position.
