Claims

[Scope of utility model registration request]

An in-roller that feeds paper across the paper, an out-roller that is provided in front of the in-roller in the paper running direction and rotates at a circumferential speed faster than the inner roller, and a blade that is provided between the in-roller and the out-roller, and is arranged in front of the in-roller in the paper running direction. A burster is equipped with a movable inner roller and a blade, and cuts the paper by applying tension to the paper due to the difference in circumferential speed between the inner roller and the outer roller, and when moving the inner roller and blade, A burst star characterized by being controlled so that it is stopped at a predetermined position when moving, and when moving from the opposite direction to the stoppable direction, it is temporarily overrun the predetermined position, and then moved from the stoppable direction and stopped at a predetermined position. .
