たことを特徴とする、穿孔機構。 A punching mechanism that perforates the paper by vertically retracting and retracting a rod-shaped punch blade from above the paper conveyed onto the punch die, the rod-shaped punch blade being held in a holder so as to be vertically slidable. At the same time, the lever moves up and down in accordance with the up and down of a lever whose one end is pivotally supported by the holder, and the lever is intermittently pressed down and urged upward by an eccentric cam rotating at the other end. The lever is configured to be able to move up and down by being returned upward by a spring, and between the lever and the rod-shaped punch blade, the punch blade can perforate the paper when the eccentric cam presses down the lever. A drilling mechanism characterized by comprising a lock prevention means whose strength is adjusted within a range that does not prevent rotation of the eccentric cam.
