PROBLEM TO BE SOLVED: To provide sufficient protection to a movable part related with forming of a pile or its disjointing simultaneously when operation of the pile worked with a printing machine is automated. SOLUTION: In a paper feeder or a discharger of a printing machine equipped with an opening part 5 capable of being shielded, a conveyance section 11 equipped with a conveyance section driving device 15 for charging or discharging is provided, and operation is automatically exchanged between two operation states of shielding bodies 7, 7' for assuring its protection. The shielding bodies 7, 7' shield the opening part 5 in a first operation state, and open the opening part 5 in a second operation state so that the pile 6 passes through that. |
