When the number of slits detected by the flow sensor 640 is 1 to 3, it is determined that the medium 1 is in a normal state, and the rotational driving speed of the drum 300 is maintained at a normal level.

And, when the number of slits detected by the flow detection sensor 640 is 4 to 6, it is determined that the medium 1 is in an abnormal state, the rotation driving speed of the drum 300 is reduced by 30% to 40%, and the flow detection Even when the number of slits detected by the sensor 640 exceeds 6, it is determined that the medium 1 is in an abnormal state, and the rotational drive speed of the drum 300 is reduced by 50% to 60% to obtain non-dispersed medium 1. As a result, it is possible to prevent problems from occurring in the device.

In addition, when the medium 1 is determined to be abnormal, the order in which the abnormal medium is introduced is checked, and when the speed of the drum 300 is reduced in a state in which the order in which the abnormal medium is introduced is checked, the abnormal medium is selected based on the abnormal medium. The driving speed of the drum 300 is reduced until the medium introduced immediately before and after the abnormal medium is transported.
