PURPOSE:To automatically permit positive dust cleaning by a device wherein a printed matter is put in a dust cleaning position input section and depressed at a dust cleaning position to issue position data, and a dust removing head section is moved along the plate drum based on the position data. CONSTITUTION:The device includes a dust cleaning mechanism 5 for displacing a dust removing head 30 to an arbitrary position along a plate drum 2 to make dust cleaning, and a central processing unit for converting dust cleaning position data from an input section 15 comprising a printed board 21 and a piezoelectric sheet 22 to control data for the mechanism 5. A printed matter is put on the input section 15 and depressed at the reversed part to detect the dust cleaning part, so that the central processing unit coverts the position data to the control data. This causes a motor 34 to stop the head 30 at a designated position on a rail 27, so that the head 30 is pushed by a cylinder 29 against the plate drum 2 to thereby remove dust. By so doing, it becomes possible to automatically move the dust removing head and to surely and easily carry out dust cleaning. |
