<p>PURPOSE:To set multiple operating time of alarms for different weather by allowing a clock main body to receive the signals transmitted from an external weather sensor and to operate alarms. CONSTITUTION:An external weather sensor 8 is installed at an outdoor position to receive rain. The user of a clock main body 1 confirms the time display section 6 of the clock main body 1 in advance and inputs the time when an alarm section 5 is to be operated according to the weather. The weather detected by a waterdrop sensor 9 provided on the sensor 8 is transmitted from a transmission section 10 as a signal. The transmitted signal is received by a reception section 2 provided on the clock main body 1 and fed to a logic circuit section 3. The circuit section 3 selects the preset alarm operating time via the inputted weather signal. The alarm section 5 is operated at the selected time. When the clock main body 1 is to be used as a weather sensing machine, the alarm section 5 is operated by the weather signal with no relation to the alarm operating time.</p> |
