  • the fourth wiring 43 may be electrically connected to the light emitting member 35 and the first cutting blade member 25.
  • the detection means 29 since the light-emitting member 35 is attached to the holder 23 instead of the base 3, it is easy to understand the correspondence between the light-emitting member 35 and the first cutting blade member 25 even if the position of the first cutting blade member 25 changes. Also, in the detection means 29, a circuit can be formed by the first wiring 37, the second wiring 39, the third wiring 41, and the fourth wiring 43. Therefore, the detection means can be introduced into existing cutting device units in which the first shaft member 5 and the second shaft member 7 are generally conductive, without making complex modifications.
  • the base 3, the first shaft member 5, and the second shaft member 7 are generally made of conductive metals such as steel and stainless steel.

  • both the first shaft member 5 and the second shaft member 7 are used as part of the electrical circuit in the detection means
  • electrical short circuits between the base 3, the first shaft member 5, and the second shaft member 7 can become a problem. Therefore, an insulating coating is required for either the base 3, the first shaft member 5, or the second shaft member 7.
  • the base 3, the first shaft member 5, and the second shaft member 7 are all large parts, it is not easy to apply an insulating coating, and there is a risk of requiring a large amount of modification costs.

  • the first shaft member 5 is prevented from becoming part of the electrical circuit by applying an insulating coating to the portion of the holder 23 that comes into contact with the first shaft member 5, or by forming the holder 23 from an insulating material.
  • the holder 23 is a small, lightweight, and inexpensive component compared to the first shaft member 5. Therefore, the detection means 29 can be introduced into existing cutting device units simply by replacing the holder 23, without the need for complex modifications that would require significant modification costs.
  • the first wiring 37, the second wiring 39, the third wiring 41, and the fourth wiring 43 are components for electrically connecting the detection means 29 and the power source 31 to form a circuit. Therefore, the first wiring 37, the second wiring 39, the third wiring 41, and the fourth wiring 43 do not need to be "wiring" in the strict sense. For example, these wirings may be partially constituted by "terminals".
  • Examples of the light-emitting members 35 include lamps and LEDs.

  • the thickness of the holder 23 between the connection terminal 33 and the light-emitting member 35 and the first main surface 51 is easily ensured. Therefore, the restraining stability of the first cutting edge member 25 against the holder 23 is easily improved. Also, the first wiring 37 is less likely to be damaged by the first cutting edge member 25. Note that, if the distance between the connection terminal 33 and the second main surface 53 and the distance between the light-emitting member 35 and the second main surface 53 are different, the above configuration may be evaluated based on the larger distance.
