Title:
BURGLAR PREVENTING TAG
Document Type and Number:
Japanese Patent JP3500602
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide burglar preventing tagS which can be stored mutually closely without issuing any erroneous alarm.
SOLUTION: When a knob 23a of a slide button 23 is located on the side of a fourth conduction spring 34, one end of a conductive plate 28 is isolated from a third conduction spring 33. When contacts abutting the third and fourth conduction springs 33 and 34 are not conducted, an IC detects the opening/ closing state of a sensor circuit provided with a sensor button 22 and controls the generation of a warning sound due to a buzzer based on the result. When the knob 23a of the slide button 23 is moved to the side of the third conduction spring 33, on the other hand, both the ends of the conductive plate 28 are in contact with the third and fourth conduction springs 33 and 34, and when it is in conduction state between the contacts on which the third and fourth conduction springs 33 and 34 are abutted, the IC does not generate any warning sound through the buzzer in spite of whether the sensor button 22 is operated or not.
