  In modern liberal societies, the norms of conduct are relaxed compared to conventional societies because they allow for diverse values. In addition, there are an increasing number of people who lack ethics and who do not recognize acts of harm to others as evil because of the so-called game brain. Furthermore, the crime rate of violent crimes such as injury crimes and robbers has increased several times in recent years compared to the high growth period. Criminal clearance rates have also declined sharply, especially for thieves, and are not sufficiently deterring against criminal intentions considering the clearance rates for thieves and the weight of punishment in Japan. Therefore, the need for crime prevention measures and self-defense is increasing not only in facilities that hold a large amount of expensive goods such as financial institutions such as banks and post offices but also in citizens such as simple passers-by and women.

  Therefore, as an example for crime prevention measures and self-defense against a thief, Patent Document 1 proposes a theft prevention device that is directly attached to a product and prevents theft. This antitheft device has a loop-shaped conductive film cord, and is configured such that, for example, a buzzer sounds when the main body is removed from a product.

  Patent Document 2 proposes an antitheft storage case in which an alarm device such as an alarm or a buzzer can be built in the storage case without taking up space, and therefore the switch mechanism cannot be seen from the outside.

  Next, the operation of the apparatus configured as described above will be described. First, the case where the target object 2 is attached to an antitheft device will be described. FIG. 4 is a flowchart when the object is attached to the anti-theft device. First, the cover member 30 is moved to the attach / detach state (S102), the opening / closing member 28 is opened (S104), and the engaging member 12 is held by the hook-like member 26 and the opening / closing member 28 (S106). . Since the opening / closing member 28 returns to the closed state by a spring force or the like, the object 2 connected to the engaging member 12 is connected to the main body 20. Next, the cover member 30 is moved to the protected position (S108), and the key member 40 is engaged with the key member engaging portion. Then, the lever member 32 is moved to the first position (S110) to enter the locked state. At this time, the lock state display unit 38 is turned on (S112) to inform the owner of the lock state. Further, the mounting portion 50 is attached to the clothes 60 of the viewer (S114). As a result, the object 2 is attached to the clothes 60 of the viewer via the antitheft device (S116).

  Next, a case where the object 2 is removed from the anti-theft device by the owner will be described. FIG. 5 is a flowchart when the object 2 is removed from the anti-theft device by the holder. First, the key member 40 is engaged with the key member engaging portion 34 (S202), the lever member 32 is moved to the second position (S204), and the locked state is released. At this time, the lock state display unit 38 is turned off (S206), and the owner is notified of the release of the lock state. Next, the cover member 30 is moved to the attach / detach state (S208), the opening / closing member 28 is opened, and the engagement member 12 and the hook-like member 26 / opening / closing member 28 are disengaged (S210).

In addition, you may remove the mounting part 50 from the observer's clothes 60 in the state which attached the target object 2 to the antitheft device. In this case, since the connection state between the object 2 and the clothes 60 of the viewer is released, it is convenient when the viewer changes clothes.

  Next, an explanation will be given of the object 2 being taken by a thief against the will of the owner. FIG. 6 is a flowchart in the case where an object is taken by a thief against the intention of the owner. The thief takes away the occupancy of the target object 2 from the owner in a manner such as picking or scratching (S302). When the robber takes away the occupation of the object 2, the robber tries to leave the owner, and the cord 10 is extended. First, when the distance between the thief and the holder is short, the cord 10 extends from the first length to the second length (S304). Then, since the state where the first tensile load acts on the cord 10 is detected by the tension detection unit 22 (S306), the alarm unit 24 outputs an alarm (S308). Thereby, the owner and the surrounding third parties know that an abnormality has occurred in the state of the object 2.

  When the cord 10 extends to the second length (S310), the tensile force acting on the cord 10 increases from the first tensile load to the second tensile load.
