Abstract: A conveying path extends from a set position in which the original sheet is set to a discharge position in which the original sheet is discharged from the image-processing device. A control unit controls an image processing unit such that the image processing unit does not execute an image processing relevant to an original sheet when an elapsed time is less than a reference time and such that the image processing unit executes the image processing relevant to the original sheet when the elapsed time is greater than or equal to the reference time. The elapsed time is time from a point of time that the control unit begins to drive a conveying mechanism in response to a reception of the command by a command reception unit until a point of time that a sensor detects the original sheet conveyed by the conveying mechanism at the detection position.
