A connector for fitting, the fitting connector is fitted to the connector of the product, the product-attached portion is attached to the product, and the detection element is attached to the product. A product theft alarm device is set to a state indicating

[0013] The first type of theft alarm device includes an accessory portion, a cable, and a monitoring alarm device.

[0014] The product attachment section is attached to a product for which theft is to be monitored. The product attachment portion has a detection element for detecting whether or not the product attachment portion is attached to the product.

As the detecting element, for example, the following switches, pressure sensors, photo sensors and the like can be mentioned. When the detection element is a switch, for example, the switch closes (or opens) when the product attachment is attached to the product, and opens (or closes) the contact when the product attachment is detached from the product. Should be adopted. As such a switch, for example, a switch in which a contact is opened and closed in conjunction with a movable piece and the movable piece is urged to open (or close) the contact can be given. If the movable piece is moved and the contact is closed (or opened) when the product attaching part is attached to the product, the contact is opened by the urging force when the product attaching part comes off the product ( (Or closing), and it can be detected that the product attachment portion is out of the product. When the detection element is a pressure sensor, if pressure is applied to the pressure sensor when the product attachment part is attached to the product, the pressure sensor is applied when the product attachment part is released from the product. No pressure is applied, and it is possible to detect the state of attachment of the product attachment portion to the product by using these pressures. When the detection element is a photo sensor, for example, if light is prevented from being incident on the light receiving portion of the photo sensor when the product attachment portion is attached to the product, the product attachment portion may be removed from the product. Normally, light is normally incident on the light receiving unit, so that the state of attachment of the product attachment unit to the product can be detected.

The monitoring and warning device issues a warning in accordance with the state of attachment of the product attachment to the product detected by the detection element.
When the product attachment portion is detached from the product, for example, when the product attachment portion is removed from the product by a thief, the monitoring and warning device issues an alarm. The alarm may be, for example, sound or light, or a combination thereof. The monitoring and alarm device
It has an alarm device that issues an alarm according to the state of attachment of the product attachment to the product. The alarm device, depending on the type of alarm,
For example, a buzzer, a lamp, a light emitting diode, or the like may be used. There may be a plurality of alarms. The alarm device may be arranged in the monitoring alarm device, or may be arranged in the product attachment part.
They may be arranged on both of them. The monitoring and warning device does not emit a warning when the product attachment is attached to the product.

A detection signal indicating the state of attachment of the product attachment portion to the product detected by the detection element is transmitted to the monitoring and alarm device via a cable. The cable has first and second main leads for transmitting a detection signal of the detection element. The first and second main leads are electrically connected to the detection element. The cable extends from the product attachment part and is electrically connected to the monitoring and alarm device. The cable may be directly connected to the monitoring and alarming device, or may be indirectly connected to the monitoring and alarming device via, for example, a repeater.

In the first type of product theft alarm device according to the present invention, the product attachment portion to be attached to the product has an attachment connector fitted to the connector of the product. The mounting connector has a shape corresponding to the connector of the product, and fits exactly into the connector of the product. When the product connector is a female connector (male connector), the mounting connector is a male connector (female connector) that fits into the product connector. More specifically, a connector for a product and a connector for mounting the product burglar alarm device of the present invention constitute a pair of male and female connectors. By fitting this mounting connector to a product connector, the product attachment portion can be mounted on the product. That is, in the first type of product theft alarm device, the product attachment portion including the detection element is attached to the product using the product connector. In addition, the detection element is thereby set to a state indicating that the product attachment portion is attached to the product. Compared with the conventional case where the product attachment portion is attached to the product using the double-sided adhesive tape, the product attachment portion can be attached to the product easily and reliably without soiling the product. Further, even when the product attachment portion is detached from the product and reinstalled, the product attachment portion can be easily and reliably attached to the product.

Many electrical appliances have connectors for outputting signals to external devices, connectors for inputting signals from external devices,
It has one or more of a connector for inputting a C power supply voltage and a connector for connecting an AC power adapter. These can be used to attach the product attachment to the product. The mounting connector of the product theft alarm device may be fitted to any of the connectors of the product. For example, a radio, a cassette tape player, an MD player, a CD player, and the like usually have a connector for audio output (for example, a connector for connecting a headphone or an earphone). When the product attachment portion is attached to any of these devices, the attachment connector may be, for example, a connector that fits into the audio output connector. For example, since a video camera usually has one or more of a video signal output connector, a video signal input connector, an audio signal output connector, and an audio signal input connector, the product attachment portion is attached to the video camera. Sometimes, the mounting connector may be, for example, a connector that fits into one of these connectors.

When the first mounting connector is fitted to the first product connector and the second mounting connector is fitted to the second product connector, the first mounting connector of the first mounting connector is operated by the internal electric circuit of the product. A fourth type of product theft alarm device can be used for monitoring theft of a product in which the first contact and the second contact of the second mounting connector are electrically short-circuited.
When the first and second attachment connectors are respectively fitted to the first and second connectors of such a product, and both the first and second product attachment portions are attached to the product, the first
The contact and the second contact are electrically short-circuited. Further, at least one of the first mounting connector and the second mounting connector is disengaged from the product connector to which the connector is fitted, and at least one of the first product mounting portion and the second product mounting portion is disconnected. When the product is out of the product, the first contact and the second contact are electrically opened.
By these, in the cable extending from each product attachment,
The electrical connection state of the first and second main leads connected to the first and second contacts, respectively, varies depending on the state of attachment of the attachment connector to the product connector.

When both the first and second mounting connectors are fitted to the commodity connector, the first main lead and the second main lead are electrically short-circuited. Therefore, when both the first and second mounting connectors are fitted to the product connector, the monitoring and warning device does not generate a warning.

When at least one of the first and second mounting connectors is not fitted to the product connector, the first
The main lead and the second main lead are electrically open. Therefore, when at least one of the first and second attachment connectors comes off from the product connector, for example, when the thief removes the first or / and second product attachment portion from the product, the monitoring and alarming device issues An alarm is issued.

In the fourth type of product theft alarm device, an alarm device may be arranged in the first or (and) second product attachment part.
