PURPOSE:To detect the runaway of a mobile instantly by equipping a signal generator comprising damping mechanism at the places where a stop mechanism of mobiles is constituted and by driving the signal generator according to the relative movement of magnetic field to a coil. CONSTITUTION:When a mobile with great energy exceeding a preload comes into collision with a block SBL, the block SBL has a bias toward the left and a magnet GT also moves in a coil COL. Therefore the output voltage appears at terminals T1, T2 and the signal showing that in the signal generator SG has occurred a collision at a speed exceeding a set one is generated. In this way collisions at speeds exceeding a set one can be detected. |
