INDICATOR, DETECTOR, AND DETECTION METHOD

摘要

[PROBLEMS] A detection technique that can, despite of its simple structure, reliably detect toppling of an article and an impact to it. [MEANS FOR SOLVING PROBLEMS] An indicator detects toppling of an article and an impact to it. The indicator is disengaged in a detector from a holding guide when the detector tilts beyond a tilt limit. The indicator has a first section shaped to roll in the holding guide when the detector tilts, and also has a second section having a smaller size than the first section and shaped so as not to prevent the first section from rolling. The first section and the second section are joined together and are separated from each other when subjected to an impact.
