<p>PURPOSE:To miniaturize this device, and to reduce the cost, by forming various timer signals to a number of electric equipment parts needing timer time signals from fixed frequency signals, and by variably controlling the load of each electric equipment part accurately. CONSTITUTION:Reference signals from a signal generator 21, such as, a crystal oscillator, etc. are input to a frequency dividing circuit 22, and frequency divided at here to put out different frequency signals f1-f3. The signals are sent out to digital timers 23, 24 putting out fixed timer signals and digital timers 25, 26 putting out repeated timer signals. Said signals f1-f3 are selection input from each timer 23, 24 and fixed timer signals are put out by putting out signals, which operate load 27, 28, such as, load for cooler recirculation or load for working a defogger, or the like from instruction portions, such as, instruction portions 31, 32 by a driver, and each load 27, 28 etc. are operated.</p> |
