A paper-feeding device, during a paper leading edge detection interval that includes an expected point in time of arrival of a paper leading edge at a paper sensor installation location, and during a paper trailing edge detection interval that includes an expected point in time of passage of a paper trailing edge, allows the signal level of a paper detection signal that is outputted to a main body section to fluctuate on the basis of an actual output value of a paper sensor, and during a transition interval from the paper leading edge detection interval to the paper trailing edge detection interval, locks the paper detection signal that is outputted to the main body section, to the signal level at the end of the paper leading edge detection interval.
