When the anti-theft device is illegally removed from the anti-theft object, an alarm is output and the anti-theft object is illegally handled. It is to inform that it is being done. In order to attach the anti-theft device to the anti-theft object, for example, when the anti-theft object is cloth, the rod-shaped part of the attachment is inserted into the housing of the anti-theft device while penetrating the cloth and connected. Attach by The anti-theft device attached to the anti-theft object outputs an alarm as described above when the mounting device is illegally pulled out and the anti-theft device is incorrectly removed from the anti-theft object. Is provided in the housing of the anti-theft device. Specifically, a movable electrode that is pushed and moved to the fixed electrode side is provided in the housing as the rod-shaped portion of the mounting tool is inserted into the housing against the urging force of the urging means. When the tool is inserted into the housing, the movable electrode and the fixed electrode are in contact. Then, by switching from a state in which the movable electrode and the fixed electrode are in contact to a state in which the movable electrode and the fixed electrode are separated by the urging force of the urging means, it is detected that the fixture has been pulled out.

In some cases, the electrode and the fixed electrode are separated from each other, and a false alarm is issued. Conventionally, in order to deal with this, as disclosed in JP-A-7-65257, that is, as shown in FIG. 15, the metallic movable electrode 100 is biased toward the side away from the fixed electrode 101. The coil spring 102 is provided so as to urge the movable electrode 100 against the housing-side fixed portion, and when the rod-shaped portion 3A of the fixture 3 is inserted,
A contact coil spring 103, which is compressed by the pushing operation force of the rod-shaped portion 3A and urges the movable electrode 100 and the fixed electrode 101 toward the contact side, is a contacted member where the movable electrode 100 and the rod-shaped portion 3A come into contact. 104 and the coil spring 102 and the coil spring 1

In general, the force acting on the coil spring 103 so that it can be pushed out strongly is also large. Therefore, in particular, when used for a long period of time, permanent distortion occurs in the coil spring, contact between the movable electrode and the fixed electrode is incompletely maintained, and it may be erroneously detected that the attachment has been pulled out. there were. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to accurately detect withdrawal of a fixture.

きるに至った。According to the first aspect of the present invention, the urging means elastically urges the rod-shaped portion and the movable electrode of the fixture with respect to the housing-side fixed portion, so that the rod-shaped portion is formed. For the movable electrode, and for the movable electrode in a direction away from the fixed electrode. When the rod is inserted into the housing against the urging means, the movable electrode is pushed and moved to come into contact with the fixed electrode. When the rod portion is further inserted from that state, the movable electrode elastically deforms and stores an elastic biasing force toward the fixed electrode. Even when the rod portion mechanically vibrates, the movable electrode is fixed to the movable electrode by the elastic biasing force. The electrodes are properly maintained in contact. Although the elastic deformation of the movable electrode occurs due to the insertion of the rod-shaped portion, the degree of the elastic deformation, that is, the strength of the elastic urging force for maintaining the movable electrode and the fixed electrode in contact with each other, is not sufficient. It is possible to set an appropriate elastic urging force separately from the urging force of the urging means that requires a proper urging force. Therefore, even when permanent setting occurs in the urging means for elastically urging the rod portion toward the detached side, the movable electrode and the fixed electrode can be kept in accurate contact with each other. Thus, even when the anti-theft device is used for a long time, it is possible to accurately detect the removal of the attachment.

Act. Therefore, the pushing operation force and the urging force opposing the pushing force are required between the rod-shaped portion and the urging means, as compared with the case where the rod-shaped portion is pushed in contact with the urging means. Design restrictions such as dimensions and shapes are relaxed, which can be advantageous in terms of practical production. Furthermore, since the movable electrode is supported by the operated member on which the push operation force of the rod portion is applied, the movable electrode can be accurately moved with the insertion of the rod portion, and the movable electrode that elastically deforms can be properly supported, Switching between contact and contact between the movable electrode and the fixed electrode can be accurately performed.

Is formed. Therefore, the urging means and the movable electrode which need to have elasticity are integrally formed,
The configuration can be simplified.

タ27がカウントを開始する。The operation of the circuit after the rod-shaped portion 3A of the mounting pin 3 is inserted into the pin insertion hole 40 and the anti-theft device 1 is mounted on the anti-theft object will be briefly described. The semiconductor switches 29a, 29c and 29d are connected to the signal processing circuit 2
In the initial state in which the signal processing circuit is not energized, the on / off state is controlled by “5”, “off”, “on”,
It is "cut". The semiconductor switch 29b is
When the detection switch S or the semiconductor switch 29a is "ON", it is turned "ON" and the semiconductor switch 29 is turned ON.
e is "OFF" only while the reset switch R is "ON". Therefore, the mounting pin 3 is inserted,
When the detection switch S is turned “ON” by the contact of the electrode piece 31 a with the electrode 6 a on the printed circuit board 6, the semiconductor switch 29 b is turned “ON”, and the power of the battery 28 is supplied to the oscillation circuit 26 and the counter 27.

If the detection switch 5 is turned on before the anti-theft device 1 is removed from the anti-theft object before the count of the set count value is completed, the power supply to the oscillation circuit 26 and the counter 27 is stopped and reset. Is done.
That is, if the detection switch 5 is not turned off during the time corresponding to the set count value, the power supply to the signal processing circuit 25 and the like is not started. When the power supply to the signal processing circuit 25 is started, the signal processing circuit 25 holds the semiconductor switch 29d in the “ON” state, and supplies power to the signal processing circuit 25 and the like regardless of whether the detection switch 5 is turned ON or OFF thereafter. The state is maintained, the oscillation circuit 26 and the counter 27 are stopped by turning off the semiconductor switch 29c, and the antitheft device 1 is started.
