Document Type and Number:
Japanese Patent JP2015200922
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a crime-prevention buzzer which is excellent in portability, and capable of securing a drive power in a long term, and sufficiently developing a function in emergency without performing battery exchange or recharging or repeated charging.SOLUTION: A crime-prevention buzzer uses a capacitor 54 as a power source instead of a battery charger or a dry battery, which offers such an advantage that electric charge can be held in a long term, that quick charging is possible, and that a risk of liquid spill or explosion can be eliminated in comparison with a general battery charger or dry battery. Thus, it is possible to secure the drive power of a buzzer 12 in a long term, and to sufficiently develop a function in emergency without performing battery exchange or recharging or repeated charging. Also, since it is not necessary to frequently perform charging, connection to a charging cable is not required, resulting in the improvement of portability.
