Abstract:
A sheet feeder picking up and transporting sheets includes a transport unit transporting sheets along a sheet transport path one by one, a gap occurrence detection unit detecting, within a predetermined section of the sheet transport path, occurrence of a gap between sheets, and a controller controlling a timing of the transport of sheets according to a result of the detection. The gap occurrence detection unit includes a first detection unit and a second detection unit. The first detection unit is configured to detect light that is emitted toward the predetermined section, reaches a converging surface thereof across the predetermined section, and converged on a receiving element thereof. The second detection unit is configured to detect light reflected by a sheet passing through the predetermined section. The occurrence of the gap is detected based on outputs from the first detection unit and the second detection unit.
