  • a cutter device characterized by having a pair of cover pieces for exposing a tip portion.
  • a cutter device wherein a hinge portion is provided between the cover piece and the main body for opening and closing the cover piece.
  • the main body is composed of two or more parts that can be separated in the direction of sandwiching the cutter, and is joined to sandwich the base end of the cutter, thereby holding the tip of the cutter in a state of protruding from the guide surface.
  • a cutter instrument characterized in that it
  • a cutter device wherein the opening angle of the cover piece is regulated to 90 degrees or less with respect to the cutter.
  • a cutter device wherein the pair of cover pieces has a fastener means for detachably connecting them so as not to open them in a closed state.
  • FIG. 1 is a perspective view of a paper cutter showing one embodiment of the present invention
  • FIG. 2 is also a perspective view.
  • FIG. 3 is a perspective view similarly showing the form at the time of use.
  • FIG. 4 is also a plan view of the inside of the paper cutter.
  • FIG. 5 is a schematic diagram similarly showing the positional relationship between the paper and the paper cutter.
  • FIG. 6 is a schematic diagram similarly showing the cutting process.
  • FIG. 7 is a schematic diagram similarly showing the cutting process.
  • FIG. 8 is a schematic diagram similarly showing the cutting process.
  • FIG. 9 is a schematic diagram similarly showing the cutting process.
  • Fig. 1 is an overall configuration diagram showing a paper cutter as a cutter device of the present invention.
  • the main body is indicated by 1 in the figure.
  • the main body 1 is a plate-like member having one side and the other side and having a thickness of about 2 to 3 mm, for example.
  • the main body 1 is provided with a pair of cover pieces 2, 2 which are flush with and integrally formed with the main body 1 and open outwardly of the main body.
  • a portion of the main body 1 corresponding to the joint with the cover pieces 2, 2 is provided between the pair of cover pieces 2, 2 for guiding the paper to be cut in one direction (arrow).
  • a linear guide surface 3 is formed.
  • a slit 4 is provided on the outer surface thereof in parallel with the guide surface 3.
