Claims

[Claims for Utility Model Registration] A disk-shaped perforation blade having a cutting edge for forming perforations on its periphery is rotatably supported around a rotating shaft in a sewing machine blade holder, and the perforation blade holder is configured to form perforations. A perforation machine that is attached to a mounting shaft of a machine and presses the perforation blade against a paper to be processed that moves relatively in the length direction to form perforations in the paper to be processed along its length. In the sewing machine blade holder for forming holes, the sewing machine blade holder includes a holder base and a sewing machine blade support, and the holder base includes:
One end is provided with a mounting hole for the mounting shaft in the perforation processing machine, and the other end is provided with an overlapping connection surface for connecting the perforation blade support along a reference plane orthogonally crossing the mounting hole, The sewing machine blade support is provided with an overlapping connection surface opposite to the overlapping connection surface of the holder base at one end, and a sewing machine blade at the other end via a rotating shaft perpendicular to the overlapping connection surface, The holder base and the sewing machine blade support are connected via a biasing means that constantly biases the overlapping connecting surfaces in a direction in which the overlapping connecting surfaces are brought into pressure contact when the overlapping connecting surfaces are overlapped,
The invention is characterized in that an expanding means is provided between each of the overlapping connecting surfaces of the holder base and the sewing machine blade support body, the expanding means acting in a direction to expand the overlapping connecting surfaces against the biasing means. Fine adjustment mechanism in perforation blade holder for perforation formation.
