Abstract
Abstract Perforations are formed at predetermined positions of a rolled record paper to facilitate cut out of the record paper at the predetermined positions. A perforating wheel for forming the perforations is made of a plurality of materials to enhance durability and reduce a cost. The positions of the perforations on the record paper are set at front and rear edges of a recorded image or at an area between recorded images so that the record paper is properly cut out.
