Patent ID: 8528894

Claim:
A method of detecting a sheet in a transport device, the transport device including a set section that includes a set face on which a sheet is set, a sheet sensor that outputs an ON-detection signal when a detection member, which is provided on the set face of the set section so as to freely extend back and forth from the lower side, receives pressure from the sheet set in the set section and retracts and outputs an OFF-detection signal when the detection member does not retract, and a feeding member that is displaced between a feed position where 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 and a non-feed position where the feeding member is separated upward from the feed position, on the basis of the detection signal output from the sheet sensor, the method comprising: after driving a feeding motor of the feeding member in the normal direction and displacing the feeding member from the non-feed position to the feed position after an OFF-detection is input from the detection member, determining whether an ON-detection signal is subsequently input from the detection member; driving the feeding motor of the feeding member in a reverse direction while the feeding member is in the feed position if an OFF-detection signal is input from the detection member after driving the feeding motor in the normal direction after the OFF-detection is input from the detection member.
