PURPOSE:To simplify operation by dispensing with a lock switch, by operating a ten-key within a definite time from operation through a mode key and inputting time data for the first time when a setting key is operated to perform the adjustment of a time. CONSTITUTION:When there is key input, it is judged whether said key input is performed through a mode key. At the time of the input through the mode key, a register 5 is cleared and, in the way indicated through the mode key, setting is performed so as to adjust present time or alarm time. At the same time, a lock state is released to set a time adjustable state. Then, a flag 1 is set to 1 and the content of a counter 3 is brought to zero. When the flag comes to 1, the count 3 is made incremental at every one sec and, when the first operation of a ten-key is not performed within 3sec, the lock state is restored and the flag is brought to 0 to recover an initial state. By this method, a lock switch selecting a time adjusting mode and a usual mode is dispensed with an constitution or operation is simplified. |
