Abstract
PURPOSE: To make it possible to set easily the set time of timer operation extending from a short time to a long time by composing a timer circuit of an oscillating circuit, dividing circuit and counter and by changing the division ratios of the dividing circuit.
CONSTITUTION: With input switch 211 ON at time t1, input line 81 and timer control line 5 are both held at a high level and transistors TR1 and TR2 turn ON and OFF respectively, so that timer circuit 15 will start operation. In timer circuit 15, when a counter counts the output of a dividing circuit and then counts up at time t2 after time A, output terminal O0 is held at the high level and output relay 114 is activated to form a short circuit between output terminals O4 and Oc4. The division ratio of the dividing circuit of timer circuit 15 can be set to one of four stages, 1, 1/10, 1/60, or 1/600, through the switching operations of switches 19 and 20, and consequently the timer-operation set time can be set to one minute, ten minutes, one hour or ten hours.
