PROBLEM TO BE SOLVED: To construct communication means for notifying of drop-off and attachment/detachment of coupling at drop-off and coupling of the connector without separately providing a disconnection detection circuit, in a device that prevents disconnection failures caused by drop-off by excessive tension and the like, of a connector of a code connector-coupled with a main communication channel.SOLUTION: Electrode terminals of a connector at a main communication channel side are bridged by friction pressure at drop-off or coupling of the connector, and the drop-off and attachment/detachment of coupling is transmitted to a monitoring part or the like. |
