  Hereinafter, an embodiment of a security sensor and a security system according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram illustrating an example of a store to which a security system is applied. The store may be, for example, a large store such as a home appliance mass retailer or a home center, a small store such as an apparel store or a general store, and an exhibition hall. In other words, any store that displays (displays) merchandise (including exhibits) can be used.

  Here, in the store 20 (a diagram overlooking the store), a product display shelf 21, a product display shelf 22, a cash register 24, and the like are provided. A plurality of products are arranged in the product display shelf 21, and the customer can use the various functions provided by the information device 5 by directly holding the product (information device 5). In the present embodiment, for example, a case where an information device capable of reproducing music, video, or the like is a product will be described as an example. However, if the information device is a device that operates by receiving power supply, The device may be used for any purpose.

  The displayed merchandise 22 is displayed in a state where the displayed merchandise is packed. Note that a theft detection tag or the like may also be attached to the product displayed on the product display shelf 22, but the description thereof is omitted because it is not a main part of the present embodiment.

  A security sensor 30 is attached to each information device 5 displayed on the merchandise display shelf 21. Specifically, each information device 5 is supported by the stand 61 via the security sensor 30. The stand 61 plays a role of supporting the security sensor 30 so that it can be inserted and removed.

  Here, the stand 61 and the security sensor 30 can be freely detached, but the security sensor 30 and the information device 5 are normally in a state where they cannot be removed. Therefore, the customer uses the information device 5 together with the security sensor 30 by hand. Although details of how to remove the security sensor 30 from the information device 5 will be described later, the removal can be performed by using, for example, a lock release member (a pin in the present embodiment).

  The stand 61 is provided with a stand cable 62 that supplies power (electrical signal for driving), and the information device 5 receives power supply from the stand cable 62 (stand 61) via the security sensor 30. Therefore, the information device 5 can be driven by the supplied power. If the information device 5 has power storage means (battery), charging can also be performed. Note that the stand cable 62 may communicate not only power but also a control signal (control electric signal), for example. In that case, the security sensor 30 also supplies a control signal input via the stand cable 62 to the information device 5.

  The security sensor 30 is provided with a monitoring device cable 8. The security sensor 30 is connected to a monitoring device (a monitoring device 10 described later) via the cable 8. Note that the monitoring device 10 may be a device described in Patent Document 1 and the like, and is not a main part of the present embodiment, and thus detailed description thereof is omitted. In brief, as shown in FIG. 2, one or a plurality (in this case, a plurality) of security sensors 30 are connected to the monitoring device 10. The monitoring device 10 includes a detection circuit 11, an alarm circuit 12, and the like, and the monitoring device 10 monitors the security sensor 30 via the monitoring device cable 8. Here, the monitoring device 10 applies a constant voltage to the security sensor 30 (a resistor 39 described later) via the monitoring device cable 8, and the detection circuit 11 detects the value of the current flowing through the security sensor 30. . When detecting a change in the detected current value, the monitoring device 10 notifies the clerk or the like that the security sensor 30 has been removed from the information device 5 in the alarm circuit 12. The detected current value changes when, for example, the security sensor 30 is removed from the information device 5, the monitoring device cable 8 is disconnected, or is short-circuited.

  The above is an example of the outline | summary of the store which applied the crime prevention system. This configuration is merely an example, and it is not always necessary to adopt such a configuration.

  FIG. 3 shows an example of an external configuration of the security sensor 30 when the security sensor 30 shown in FIG. 1 is viewed from the A to D directions. The view seen from the direction A corresponds to FIG. 3A, the view seen from the direction B corresponds to FIG. 3B, and the view seen from the direction C corresponds to FIG. The view seen from the direction D corresponds to FIG.

  As shown in FIG. 3A, a first connector 31 that functions as a connection unit that connects the information device 5 and the security sensor 30 and a communication interface is provided on the security sensor 30. As shown in FIG. 3B, the first connector 31 is provided with a lock mechanism 36 (36 a, 36 b) that prohibits removal of the information device 5 from the security sensor 30. The lock mechanism 36 is usually provided by an elastic member so as to protrude outside the first connector 31 (in the direction of the arrow E or the arrow E ′), and when the information device 5 is attached to the security sensor 30 or security When the information device 5 is removed from the sensor 30, the information device 5 is temporarily pushed into the first connector 31, and returns to the original state (protruded state) during attachment or removal.

  Here, as shown in FIG. 3D, a pin insertion port 35 is provided on the side surface portion of the security sensor 30 as an opening for receiving the lock release member. The pin insertion openings 35 are respectively provided on the left and right sides of the side surface portion of the security sensor 30, and are formed in a shape in which a lock releasing member (pins 60 (60a and 60b)) can be inserted from the outside of the sensor. The information device 5 is removed from the security sensor 30 when the pins 60 are inserted from the left and right sides of the side surface of the security sensor 30. That is, when the pin 60 is inserted from both the left and right sides of the side portion of the security sensor 30, the lock mechanism 36 provided in the first connector 31 is pushed into the connector 31, whereby information from the security sensor 30 is obtained. The device 5 can be removed. In addition to the pin insertion port 35, an opening (cable connection port 34) to which the monitoring device cable 8 is connected is provided on the side surface portion of the security sensor 30.

  As shown in FIG. 3C, the bottom part of the security sensor 30 is provided with a connection part that connects the security sensor 30 and the stand 61 and a second connector 32 that functions as a communication interface. The security sensor 30 inputs a signal (power, control signal, etc.) supplied via the stand cable 62 at the second connector 32, and directly inputs the input signal to the information device 5 at the first connector 31. Output toward.

  In addition, a sensor lever 33 is provided on the security sensor 30 as shown in FIGS. The sensor lever 33 detects attachment to the information device 5 and removal of the information device 5. The sensor lever 33 is normally (when the security sensor 30 is not attached to the information device 5), and a force is applied in the direction of arrow F shown in FIG. 3C by an elastic member (for example, a spring). The sensor 30 protrudes from the main body. While the security sensor 30 is attached to the information device 5, the sensor lever 33 is pressed in the direction of the arrow F ′ by the information device 5 and pushed into the main body.

  Here, an outline of the lock mechanism 36 when the information device 5 is attached to the security sensor 30 and when the information device 5 is detached from the security sensor 30 will be described. FIG. 4 shows an enlarged schematic view of the lock mechanism 36a and its peripheral area in the security sensor 30 shown in FIG. 3 (b). Here, the lock mechanism 36a will be described as an example, but the same applies to the lock mechanism 36b.

  As shown in FIG. 4A, a predetermined space (hereinafter referred to as a connector insertion space) 5 a is formed at the bottom of the information device 5 in order to connect to the first connector 31 in the security sensor 30. . The connector insertion space 5a is provided with a recess 5b, and the claw portion 361 of the lock mechanism 36a fits in the recess 5b.

  Since the lock mechanism 36a is normally provided in a state of projecting to the outside of the first connector 31 (in the direction of arrow E) by the action of the elastic member 41a, the lock mechanism 36a is configured as described above when the information device 5 is attached. It is pressed in the direction of arrow E ′ by the internal shape of the connector insertion space 5 a and is pushed into the first connector 31.

  The shape of the claw portion 361 of the lock mechanism 36a gradually increases along the direction (arrow F ′ direction) from the distal end side of the first connector 31 toward the main body portion side (arrow E ′). The degree of projecting in the direction) is increased. Therefore, when the information device 5 is attached, as shown in FIGS. 4A to 4C, a store clerk or the like performs a special operation only by applying a pressing force in the direction of the arrow F ′ to the information device 5. The information device 5 can be attached to the security sensor 30 without performing the above. Specifically, when a clerk or the like applies a force in the direction of arrow F ′ to the information device 5 in the state shown in FIG. 4A, the first connector 31 is shown in FIG. 4B. The lock mechanism 36a (claw portion 361) is gradually pushed into the inside. A store clerk or the like further applies a pressing force in the direction of arrow F ′ to the information device 5, and the position of the claw portion 361 and the recess 5 b in the connector insertion space 5 a in the direction indicated by the arrow F ′ (or arrow F) is When they coincide with each other, as shown in FIG. 4C, the claw portion 361 is fitted into the concave portion 5b. That is, the claw portion 361 of the lock mechanism 36a is restored to the original state (projected state) in the concave portion 5b of the connector insertion space 5a by the action of the elastic member 41a. As a result, the information device 5 is attached to the security sensor 30.

  On the other hand, when the information device 5 is detached from the security sensor 30, due to the shape of the claw portion 361 described above, the store clerk or the like cannot freely remove the lock without the lock release member (pin 60a). Therefore, as shown in FIG. 4D, the store clerk or the like inserts the lock release member (pin 60a) into the pin insertion port 35 and removes the information device 5 from the security sensor 30 during the insertion of the pin. At this time, the lock mechanism 36a (claw portion 361) is pushed into the first connector 31 by the pressing force in the direction of the arrow E 'by the pin 60a.

  Next, an example of the internal configuration of the security sensor 30 shown in FIG. 1 will be described with reference to FIG. FIG. 5 shows an internal configuration of the security sensor 30 viewed from the direction B shown in FIG. That is, an internal configuration corresponding to the external configuration shown in FIG.

  Inside the security sensor 30, a control board (first connector board 40, second connector board 38), a switch unit 37, and a resistor 39 are provided.

  The first connector substrate 40 controls signal communication and the like by the first connector 31, and the second connector substrate 38 controls signal communication and the like by the second connector 32. Note that these control boards (40, 38) do not process signals (power and control signals) input via the second connector 32. That is, the security sensor 30 does not intervene with respect to the circuit inside the product (information device 5). Therefore, no malfunction or damage is caused to the information device 5.

  The switch unit 37 has an internal lever 37 a and operates in conjunction with the sensor lever 33. Specifically, while the security sensor 30 is attached to the information device 5, the sensor lever 33 is pressed into the security sensor 30. At this time, the internal lever 37a receives the pressing force and is pushed into the switch unit 37. As shown in the schematic diagram of the circuit configuration in the dotted line frame in the figure, the value of the current flowing through the security sensor 30 changes due to the movement of the internal lever 37a, whereby the monitoring device 10 changes the detected current value. Can be detected.

  As described above, according to the present embodiment, it is possible to achieve both the mounting strength of the security sensor 30 to the product and the appearance when the security sensor 30 is mounted.
