Abstract

PURPOSE: To read data at the necessary points of time when the action conditions must be recorded when accidents happen, by using nonvolatile RAM (Random access memory).
CONSTITUTION: When signals being proportional to the travelling speed of cars are obtained by means of a speed generator TG, a code converter VD, a distance cunter CT and a constant distance integrating meter CO are provided with the signals, and a first memory R1 and a second memory R2 are furnished with reading commands from a memory circuit command conversion FP containing a flip-flop. In this case, the repetition that memory in the other memory is eliminated when memory in one memory overflows and new information is memorized is performed, and the travelling distance information of cars and speed information corresponding to said travelling distance information are memorized to two memories alternatively and continuously.
