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. extends to the outside of the paper path, the extending portions thereof are slidably connected to both sides of the frame, and are mounted on both sides of the cutter or both sides of the support member about a fulcrum so as to be freely up and down with screws. A burster comprising a leaf spring having a receiving piece formed on one side and a braking piece elastically connected to the frame on the other side.
