Therefore, it is characterized in that it has a compartment divided into a U-shaped cross section opening on the side of the outer circumferential surface of the roll, and an air flow forming means for forming an air flow flowing in the longitudinal direction within the compartment. The scraping treatment structure of the doctor device. (2) The scraping treatment structure according to claim 1, further comprising a plate moving means for moving the partitioning plate to a position where its tip is in contact with the outer circumferential surface of the roll and to a position away from the outer circumferential surface. , the plate moving means is adapted to hold the partitioning plate at a position in contact with the outer circumferential surface of the roll when an airflow is being formed in the compartment by the airflow forming means; The scraping treatment structure of the doctor device is characterized by: (3) The scraping waste disposal structure according to claim 1 or 2, further comprising a paper breakage detection means for detecting that the paper stock received by the outer peripheral surface of the roll and conveyed has broken; When a paper break is detected, the partitioning plate is controlled to be in a position where it is in pressure contact with the roll outer circumferential surface with a constant pressing force, and the doctor blade is in a position away from the roll outer circumferential surface. A scraping treatment structure for a doctor device, characterized in that it is equipped with a control means for controlling it so that.
