PROBLEM TO BE SOLVED: To suppress decline in processing efficiency caused by retry, in a configuration to perform retry of paper feeding operation of sheets from the top face of a sheet mounting tray. SOLUTION: A sheet carrying device includes a pickup roller 6 for sending out sheets on a document mounting tray 5 into a carrying path one by one; a sheet carrying device 116 for rotating the pickup roller 6; a control part for controlling a roller first driving motor 116; and a carrying delay detecting part for detecting delay in sheet carrying by the pickup roller 6. The control part controls the roller first driving motor 116 in a case where the delay in the sheet carrying is detected by the carrying delay detecting part, so that the pickup roller 6 restarts rotation after once stopped and that start time acceleration, which is acceleration from the restart of rotation to arrival at predetermined speed, becomes lower than first start time acceleration from start of rotation of the pickup roller 6 to arrival at the predetermined speed in a case where no delay occurs in the sheet carrying.
