Abstract

PURPOSE:To prevent the loss due to careless dropping and warn the user of destruction due to sports and so on, by generating alarm due to impulse in the portable device such as a watch and a camera. CONSTITUTION:In the electronic clock, the time reference signal from oscillating circuit 1 including the quartz oscillator is divided by frequency dividing circuit 2 and is counted by counting circuit 3 and becomes time information, and this information is displayed through driving circuit 4 as the time on display means 5, and the driv- ing circuit drives sound emitting means 6 such as a piezoelectric buzzer and an electromagnetic speaker in accordance with the time. External operation material 7 is provided for operate manually the counting circuit and the driving circuit. Further, in this invention, the alarm signal is generated by impulse detecting means 9 when the impulse of a set value or more is received, and alarm is generated by the sound emitting means. Thus, the loss due to careless dropping is prevented, and the user is warned of the danger of destruction due to sports and so on.
