Abstract
A reading unit is configured to capture an image of a shadow generated at a leading end of a document, and a control unit is configured to estimate a thickness of the document based on a pixel value of the shadow. A multifeeding error is displayed on a display unit when it is determined as thin paper in a thick paper determination. The control unit turns multifeeding detection to OFF and stands by until a feeding is completed, and upon completion, returns the multifeeding detection to ON.
