<p>PROBLEM TO BE SOLVED: To provide an electronic device which has the same reliability as the conventional one while taking out the minimum current from a battery. SOLUTION: Each block is serially connected to a CPU 2. When signal transmission is necessary between the blocks, signals are transmitted using photo couplers 6. When either one of the blocks does not operate properly or is applied with voltage below the operating voltage, a current path is secured with current bypass circuits 7A, 7B, each parallelly connected to each block, to obtain a proper operation of the system as a whole.</p> |
