Hanging the buzzer case 58 by passing a nail (not shown) provided on a wall or column inside or outside the building through the hanging hole 64 of the buzzer case 58, or leaning it against an appropriate location, and hanging the buzzer case. If the conductive plug piece 45.46 of the case 4 is inserted into the socket 56.57 of the case 58 and the case 4 is connected to the buzzer case 58, the case 4 will receive the vibration when an earthquake occurs. The vibration switch 41 inside swings and comes into contact with the conductive ring 39, the power supply circuit of the electromagnet 10 is closed, and the unlocked deformable cam disk 17 rotates and stops at the normal position. The pressed elastic suppression switch piece 26 contacts the elastic pressure-receiving switch piece 30, and the power supply circuit of the miniature light bulb 2 is closed, and the miniature light bulb 2 lights up to brightly illuminate the surrounding area at night, and at the same time, the power supply circuit of the buzzer 59 is closed. Even if you are woken up early from a deep sleep by the sound of the buzzer 59 closing and the sound of the buzzer 59, you can carry out evacuation operations safely and smoothly without getting confused and carrying the case 4 that automatically turns on the light.

Therefore, if the buzzer case 58 is separated from the case 4 during evacuation, the circuit of the buzzer 59 will open and the sound will stop.
The miniature light bulb 2 can be carried while keeping the power supply circuit closed by suppressing the elastic push switch piece 26 by stopping the fixed position of the deformable cam disk 17.

In addition, when the earthquake has stopped or when you have evacuated to a safe place, or when it is daytime, for example, the deformable cam disk 17 can be activated by using the pull cord 35 or other appropriate method as shown in the embodiment of the present invention.
4, the electromagnet 1 returns to its previous position and is in a de-energized state.
0 again, the elastic suppression switch piece 26 separates from the elastic pressure receiving switch piece 30 and the power circuit of the miniature light bulb 2 opens and the light goes out, so the buzzer case 58 and the case 4
can be linked together and used effectively in preparation for earthquakes.
