PURPOSE:To prevent malfunction of the system by providing a means in which at least one of the setting operation of a setting value, the registration of the setting value and the automatic registration time is not affected by power interruption or power recovery. CONSTITUTION:The device is so designed such that any of the setting operation of a setting value, the registration of the setting value and the automatic registration time is not affected by a change in the state of electrification. Thus, even if power interruption or power restoration takes place on the way of the setting of a setting value, the setting value in the midway of the setting is not erroneously registered but the normal setting operation is executed continuously. Thus, the possibility of a value other than a desired setting value is registered in error and of malfunction of the system are precluded. Thus, even if power interruption or power recovery takes place during the automatic registration wait time after the end of key operation for setting a numeral, since the setting value is registered automatically after a prescribed time elapses as in the normal state, the correction of the setting value during the automatic registration wait time is attained. |
