SENSOR OF ANTITHEFT WARNING DEVICE

PROBLEM TO BE SOLVED: To provide a sensor of the antitheft warning device which increases the antitheft effect of an article and decreases the number of sensor codes from the article. SOLUTION: The sensor of the antitheft warning device which receives the detection signal from a detection part mounted on an article 2 by a state decision means (signal processor 12) and sends a warning corresponding to the signal state to prevent the article from being stolen is equipped with multiple detection parts 41 and 4N which are electrically linked together and a signal line 8 connecting the detection parts and state decision means (signal processor 12), and consequently while the antitheft effect of the article by the detection parts is increased, the number of signal lines is decreased to make it easy to handle the article.
