PURPOSE:To conduct electric discharge through the sure shortcircuiting of integration capacitors, by discharging integration capacitors by means of dis charging switches connected in parallel to integration capacitors in case of an acceleration signal being the one that does not accompany danger, while the detection output of an acceleration sensor is integrated. CONSTITUTION:The 1st imperfect integration circuit 4 which conducts the imperfect integration of an acceleration sensor 1 detection signal, and the 2nd imperfect integration circuit 5 which conducts the imperfect integration of the circuit 4 integration output, have integration capacitors 4a, 5a and resistors 4b, 5b connected between respective reversing input terminals and output terminals, and discharging switches 6a, 6b connected in parallel to capacitors 4a, 5a are actuated by receiving a reset signal in case of an acceleration signal being the one that is accompanied by no danger. Even if the detection output of the sensor 1 is fed to the circuits 4 and 5, the reset signal is fed in case of the acceleration signal being the one that is accompanied by no danger, and switches 6a, 6b are shortcircuited, and capacitors 4a, 5a are discharged. |
