Claims

[Scope of utility model registration request]

A paper path is formed with perforations in the frame to convey the form folded in a zigzag pattern, and at both ends of this paper path there is a pull-in roller that pulls in the form while holding it in place, and a discharge roller that rotates at a circumferential speed faster than the circumferential speed of the pull-in roller. A cutter made of a plate is provided in the paper path, and the cutter is made of a plate material and the lower edge thereof has a guide surface that is bent downward in the direction in which the form enters. A burster characterized in that both sides of the frame extend outside the paper path, and the extending portions are connected to both sides of the frame so as to be slidable and fixed at any position.
