Abstract

PURPOSE:To obtain an acceleration sensor which can perform the continuous measurement of the acceleration, by providing the acceleration detecting pendulum with the acceleration detecting filter attached and thus securing the conversion into the acceleration via the motion of the pendulum. CONSTITUTION:Arc-shaped acceleration detecting filter 4 is attached to the lower part of acceleration detecting pendulum 2. For example, pendulum 2 swings toward the direction shown by arrow B by the negative acceleration when the car runs and stands still. According to this, the density changes for filter 4 provided between light emitting diode 6 and phototransistor 7, and the light transmitted through the portion according to the level of the acceleration of filter 4 is detected at transistor 7. This light is then sent to the display unit in the form of the electric output, and the corresponding acceleration is displayed. As the density of filter 4 is varied continuously, an acceleration sensor which performs the continuous display of the acceleration change can be obtained.
