DETECTION OF WIRE IN TUBE AND DETECTOR

摘要

PURPOSE: To provide a detecting method and device for the wire in a tube capable of detecting whether the wire exists in an opaque tube or not and in what way the wire is arranged in the tube by a simple method. CONSTITUTION: A center member 1 is formed into a cylindrical shape having a central hole 1a and has a groove 1b in a part of the outer peripheral surface along the longitudinal direction thereof. A first mark 4 is formed near the top end of the shaft core 1. A wire-shaped member 2 has flexibility and is supported freely turnably at the shaft center 1 in a wire-shaped member supporting part 1d through a through-hole 1c from the upper part of the central hollow 1a. The wire-shaped member 2 is extruded outside from the through-hole 1c and an arc part 2a is formed between the through-hole 1c and the wire- shaped member supporting part 1d when an operator pushes the wire-shaped member 2 into the central hole 1a. A second mark 5 is formed on the wire- shaped member 2.
