PURPOSE:To make possible an adjusting treatment without cutting the electric source of a controlled device by performing the change of an output state when a time setting and a change of a program content are practised during the operation. CONSTITUTION:Usually, a counter of a day of the week and a time 3 are stepped by the signal from a watch clock circuit 2. After comparing 8 a time added one minute to the clock time with a content of a memory 1 memorized in a program, a data of output nimber and of a data of output state are allowed to memorize to an output buffer 9 temporarily by a coincidence signal and when it reaches to the present time, it is outputted 10. When a signal which changes the content of a counter 3 and of a program 1 is input from an input key 7, an offering signal Int occurs in an offering signal generating circut 11 and a buffer output forbidden signal Inh 2 is output from a comparator 8 is output and holds a memory data of an output buffer 9 until the adjustment is completed. |
