First Claim
1. A theft preventive apparatus comprising:
- an attached-state detecting device exposed outside a box for detecting a state of attachment to an object of theft prevention,alarm output means mounted in said box for detecting removal of said box from the object of theft prevention based on information from said attached-state detecting device and outputting an alarm at the time of detection of the removal,a battery mounted in said box for driving said alarm output means, anda power supply switch for a turning power supply on and off between said battery and said alarm output means;

Abstract
A theft preventive apparatus is attached to a commodity or the like exhibited in a shop, for outputting an alarm when detached therefrom.
Conventionally, a battery is used as a power source for driving an alarm output device, and power supply is turned on and off by moving the battery. Even in a non-use state, an operation could be started inadvertently by vibration or the like.
The theft preventive apparatus of this invention includes an attached state detecting device (3, 103) exposed outside a box (2) for detecting a state of attachment to an object of theft prevention, alarm output means (G) mounted in said box (2) for detecting removal of said box (2) from the object of theft prevention based on information from said attached state detecting device (3, 103), and outputting an alarm in time of detection of the removal, a battery (V) mounted in said box (2) for driving said alarm output means (G), and a power supply switch (6) for turning power supply on and off between said battery (V) and said alarm output means (G). Consequently, by turning off the power supply switch, the theft preventive apparatus, even in a non-use state, does not start operating inadvertently by vibration or the like, thereby avoiding wasteful consumption of battery power.
