Abstract

PURPOSE: To avoid the operation mistake, by displaying successively the operating sequence of the buttons in accordance with the preceding operation and at the same time showing clearly the completion of one operation each time.
CONSTITUTION: In case the prescribed program source is set via a timer, the catch is operated to close the switch S1, to trigger the monostable multivibrator 9, to set the flip-flops 16W18 and to light up the LEDs of the LED driving circuits 29W31 respectively. With glowing of these LEDs, the next time setting is urged. Then the timer ON-key with its LED lit up is pushed to close one of the switches S2WS4. Thus the flip-flops 19W21 are reset to turn off the LED. At the same time, the LEDs of the LED driving circuits 32W34 corresponding to the timer key are lit up to urge the time setting operation. In such way, the LEDs are turned on and off successively based on the operating sequence.
