摘要： A sheet feeding apparatus includes a sending element of an ultrasonic sensor (17) for outputting ultrasonic waves, a drive circuit (41) for supplying the sending element of the ultrasonic sensor (17) with a drive signal for driving the sending element, a receiving element of the ultrasonic sensor (18) disposed opposite the sending element of the ultrasonic sensor (17) across a sheet transfer path in the sheet feeding apparatus, and for receiving the ultrasonic waves, a setting unit (26) for setting a threshold for the detection of transfer of the plurality of paper sheets (100) by using the output of the receiving element of the ultrasonic sensor (18) at the time of stopping of the output of the sending element of the ultrasonic sensor (17) as a basic value, and a detection unit (26) for detecting transfer of the plurality of paper sheets (100) by comparing the output of the receiving element of the ultrasonic sensor (18) with the threshold.
