It is characterized in that a confirmation device is provided.

The present invention is also characterized by being portable and driven by a battery as a power source. The present invention is also characterized in that the light receiving element is provided in the tip of a rod antenna-shaped cylindrical body. The present invention is also characterized in that a glass fiber for guiding the light of the indicator light of the terminal from the tip is formed in the shape of a rod antenna, and the light receiving element is arranged at the other end of the glass fiber.

The present invention is also characterized in that the rod antenna-shaped cylinder or the glass fiber is detachable from the housing.
