Abstract

A sheet conveying device includes a sheet supply portion, a measurement processing portion, a first determination processing portion, and a second determination processing portion. The sheet supply portion supplies an uppermost sheet in a stack of sheets lifted by a lift portion to a conveying path. The measurement processing portion measures, every time the sheet is supplied, an elapsed time from a start of supply of the sheet to a time when the sheet is detected by a detection portion. The first determination processing portion determines, every time the elapsed time is measured, whether or not a measured measurement time is less than a reference time. The second determination processing portion determines, when it is continuously determined that the measurement time is less than the reference time, whether or not a delay has occurred in the supply of the sheet.
