Abstract
A fixed blade and a movable blade in which a cutting portion end face of the movable blade is orthogonal to a side surface of the movable blade, and the movable blade is brought into sliding contact with the fixed blade to cut a recording sheet. A cutout groove for forming a cutting residual portion in the recording sheet is formed in the cutting portion of the movable blade. A slant surface or a curved surface is formed at an intersection of the side surface of the movable blade, a cutting portion end face of the movable blade and the inner peripheral surface of the cutout groove.
Claims12
A sheet material cutter comprising;
- a fixed blade and a movable blade, the sheet material cutter being configured to bring the movable blade into sliding contact with the fixed blade to cut a sheet material disposed between the fixed blade and the movable blade,
- the movable blade comprising one or more cutout grooves for forming one or more cutting residual portions in the sheet material when the movable blade is brought into sliding contact, with the fixed blade,
- the movable blade further comprising respective slant surfaces or curved surfaces having a generally triangular periphery and being located at respective intersections of a side surface of the movable blade which does not face the fixed blade, respective end faces of a cutting portion which are orthogonal to the side surface and respective inner peripheral surfaces of the cutout grooves, and
- wherein each corresponding one slant or curved surface has a first edge at an adjacent end face of the moving blade, a second edge at an adjacent cutout groove inner peripheral surface, and a third edge at an adjacent side face, said first edge extending for a length less than a length of said adjacent end face, said second edge extending for a length less than a length of said adjacent cutout groove inner peripheral surface, said third edge extending for a length less than a length of said adjacent side face.
