PURPOSE:To shorten a time for setting and also to extend a range of set time by a system wherein an initial time value setting on a counter is carried out with the same setting means, and the setting is brought in hour/minute digits on a clock counter and in minute/second digits on a time counter. CONSTITUTION:When there works an output on an output terminal 0 of a setting control circuit S3 at actuating a time digit setting key S1, an hour digit setting circuit C2 is actuated and an hour digit on an hour digit counter TC1 is added in trioctal format. For completion of a desired hour digit setting the key S1 is stopped operating. Then, when a minute setting key S2 is actuated and there works an output on an output terminal U or D, a minute digit setting circuit C5 adds or substracts a minute digit on the counter CT1 in decimal format according to the output. Next, when there works an output on the terminal U or D of the circuit S3 at the time of the key S1 actuation, a minute digit setting circuit F3 adds or subtracts in decimal format according to the output. The setting is completed by stopping the key S1 operating. Then, where there works an output on the output terminal 0 at the time of the key S2 operation, a second digit setting circuit F3 adds a second digit in sexadesimal format. The counter set as above is transmitted to a clock memory or counter and displayed on a display 5. |
