PURPOSE:To temporarily raise and separate a dirt wiping-off pad from the upper end face of a drum can so that the shock to the pad when the pad is separated from the lid of the drum can be reduced. CONSTITUTION:A drum can 1 is placed and rotated on a turntable 5 rotated by means of a main section 4 with its axis in the vertical direction and each lid which closes the opening of the can 1 is provided almost on the same circumference on the upper end face. A pad 17 is installed to the front end section of a pad moving mechanism 18 and, at the same time, moved over an extent R in the radial direction of the can 1 or raised at the moving time so as to prevent the pad 17 from coming into contact with the lids. The raising extent of the pad 17 is decided based on the measured results of a noncontact distance measuring instrument 20 installed to the front end of a fitting frame 19 and constituted of a distance sensor which detects that the distance to an object is smaller than a set value.
