<p>PURPOSE: To provide an electronic equipment in which runaway during program execution can be prevented, and a battery life can be extended. CONSTITUTION: When the deterioration of the voltage of a driving battery 20 is detected by first and second power supply voltage detecting means 23 and 24, a driving voltage switching means 44 and first and second D flip flops 52 and 53 are switched by a CPU 28 by a pertinent detection signal, and a driving voltage and driving frequencies are deteriorated.</p> |
