    摘要: An insulation resistance drop detector 50 and a method of detecting a state of malfunction of the detector 50 are provided. When open of a coupling capacitor Co or malfunction of a low pass filter 53 is occurred, a time constant of the low pass filter 53 is decreased and a rising time of an output of the low pass filter 53 against an output of a pulse signal P1 becomes shorter than that in a state of normal. Thereby, malfunction of the detector 50 can be detected based on the output of the filter 53 corresponding to change of frequency of the pulse signal P1.

    摘要: The present invention relates to a theft preventive apparatus to be attached to an object of theft prevention for detecting a preliminary stealing act by e.g. issuing alarm, and relates also to a radio wave receiving signaling device to be used with the apparatus. Conventionally, there has been a problem of the alarm output means being rendered inoperative when a sudden shock is applied to the theft preventive apparatus for example. According to the present invention, a circuit board (6) of alarm output means (AO) disposed inside a box (2) to be attached to the object of theft prevention is retained to one first side wall portion (2a) of a pair of opposed wall portions (2a), (2c) of the box, and the other side second wall portion (2c) retains a first-kind constituting element (FE) of the alarm output means (AO). A power-supply contact member (CE) formed integrally with the first-kind constituting element (FE) is adapted to contact a first-kind contact (FC) having a contact face extending toward the second wall portion of the circuit board (6). And, the power-supply contact member (CE) is comprised of a coil spring which can expand and contract in the approaching/departing direction of the pair of wall portions (2a), (2c) and which is disposed under a state contracted from its maximally expanded state. Then, the electric contact may be maintained against sudden shock.

    摘要: The present invention relates to a detector for theft prevention used in contact with a commodity or the like exhibited in a shop.Conventionally, an operated portion for contacting a commodity or the like is pivotable only in one direction from a projected position. The commodity or the like cannot be moved in directions requiring the operated portion to pivot in directions other than that direction. A forcible movement would damage the operated portion.In a detector for theft prevention of this invention, a switch (3) provided for a box (2) thereof has a pivotable operated portion (3a) biased to return to a position projecting from a surface (2c, 2d) contacting an object of theft prevention (E). The operated portion (3a) is pivotable in a plurality of directions including at least two opposite directions (e1, e2). The detector for theft prevention is properly operable for movements in varied directions of the object of theft prevention (E).
