Abstract
PURPOSE: To secure the output of the timer signal before the set time by having the conversion between the set time and the fixed time delivered from the timer signal with every switching of the display between the actual time and the timer time.
CONSTITUTION: Synchronous-type register 24 featuring both functions of the memory and the switch memorizes temperarily the time during which the high-level pulse is delivered from signal generator 22 at the moment when the display is switched from the timer time to the actural time, and then delivers the pulse featuring the duration memorized when the timer signal is delivered at time t1 from terminal 17. This time coveres the period during which the timer time is substracted to display the actual time after operation of timer display terminal 7. Actual time converter 25 converters the output signal of register 24 into the time at the actual time, and delivers the timer signal at time t2 through terminal 23. Thus if gate circuit 11 featuring the 120:1 relation is made to pass between the actual time and the duration of the output signal of generator 22, the signal of 15-second duration sent from register 24 are turned to the timer signal of 30-minute duration to be delivered before the set time.
