[0003]

If the signal transmission is not successful in the entire apparatus, it is necessary to confirm whether the signal transmission is correct at each electric connector. For this reason, in the conventional electric connector, after the first connector and the second connector are detached from each other, confirmation is made at their contact portions (for example, see Japanese Patent Application Laid-Open No. 5-288793), or After making the connector and the second connector half-fitted, confirmation was made at their contact points (for example, see Japanese Utility Model Laid-Open No. 2-61084).

However, according to these methods, even if there is a connector or the like having poor contact, when the connectors are detached from each other or when the connectors are brought into a half-fitted state.
Due to the sliding effect of the contact portion, the contact characteristics may be temporarily recovered. For this reason, it is difficult to grasp the cause at the time of checking at each contact, and the problem may not be solved.
