Abstract: PURPOSE:To obtain an integrating range finder of an automobile, etc., which is simple and high in reliability, by using an EPROM as back-up against a state that a battery is off. CONSTITUTION:Whenever a pulse signal is obtained from a car speed sensor 3 for generating a signal when an automobile runs, a microcomputer 4A reads out an integrating range from a prescribed address of an RAM 4B.
