Claims

[Scope of utility model registration request]

A conductive plate made of conductive material perpendicular to the axial direction is slidably inserted at an appropriate position at the end of the core pipe, and a pair of conductive plates made of conductive material are inserted from the plate on the inner wall of the core pipe and at an appropriate part at the tip. The terminals are protruded so as to face S' at the position where the conductive plate comes into contact with both terminals, and a protrusion made of an electrically conductive material is protruded from an appropriate portion around the tip of the core pipe, and a shaft for housing the core pipe is provided. A protrusion that comes into contact with the protrusion when the core pipe moves forward in the distal direction is provided protrudingly from the protrusion on the inner wall of the cylinder and at the position of the tip.Furthermore, a battery is housed in the axial cylinder, and a battery is inserted from outside the axial cylinder. A visible light emitter is provided, and a conductive wire is arranged so that the light emitter emits light when the conductive plate comes into contact with a pair of terminals and the protrusion from the tip of the core pipe comes into contact with the protrusion on the inner wall of the shaft cylinder.
