Abstract
A conveying device which can determine whether an error occurred therein. When a transmission unit is in a transmission state, a sheet feed roller is driven by a DC motor to perform first driving for conveying a sheet up to a conveying roller. The occurrence of an error with respect to the sheet feed roller is determined based on information obtained from an encoder during the first driving. When the occurrence of an error is determined, second driving is performed. A conveyance error is determined based on a count value during the first driving and a count value during the second driving, which are both obtained from the encoder.
