ABSTRACT:
To implement a detection technique in which a tumble of and a shock to on articles can be detected even with a simple and low-cost structure.An indicator according to the present invention for detecting a tumble of and a shock to an article moves away from a holding guide in a detector when the detector inclines and goes beyond a limit for inclination. The indicator includes a first part in the shape of rolling on the holding guide when the detector inclines, and a second part smaller than the first part and in the shape of not preventing the first part from rolling. The first part and the second part join together and separate when receiving a shock.
