In addition, as in Patent Document 1, it has been proposed to turn on / off the power supply to a part of the circuit when the IC receives a specific command, but the circuit that issues the command is operating. , With some power consumption. Therefore, when the use of the battery in such a tag is examined, it is found that a battery that satisfies the following constraint conditions is required.
(1) In order to reduce the size of the tag, it is desirable that the battery be operated with a small battery such as a button battery.
(2) We do not want to supply power to the wireless communication circuit until the use of a battery with a small capacity such as a button battery or the start of use of the tag. This is because if the power supply is continued before the start of use, the actual usable period is shortened. Therefore, it is desirable not to use the electric energy or to hardly use it until the start of use.
(3) If the power supply is started by the switch, the number of parts increases. Also, if the switch is accidentally turned off while the tag is in use, it will not be useful at times. Therefore, a switch that can be turned on / off cannot be used.
(4) If a configuration in which a battery box is provided with a lid and a battery is inserted at the start of use, or a configuration in which power supply is started by pulling out an insulating sheet between the battery and the contact, a waterproof property cannot be provided. If it is not waterproof, the tag cannot be attached to an umbrella, bicycle, etc., and the range of use will be limited.

  In order to satisfy at least two of the above-described conditions at the same time, the present invention can be implemented as the following modes.

(2) In the above embodiment, the power supply device includes a pressing unit, a first conductor pattern connected to the battery, and a second conductor pattern spaced from the first conductor pattern and connected to the wireless communication circuit. And a conductive spring capable of conducting between the first conductor pattern and the second conductor pattern, and before the pressing portion is pushed down, the conductive spring is connected to the first conductor pattern. The conductive spring does not conduct between the second conductor patterns, and after the pressing portion is pressed down, the conductive spring is urged by the conductive spring to cause the first conductor pattern and the second conductor to move. The state in contact with the pattern may be maintained, and the first and second conductor patterns may be irreversibly conducted.
According to this aspect, the first conductor pattern and the second conductor pattern can be irreversibly conducted with a simple configuration.

(3) In the above aspect, the first and second conductor patterns are both disposed on one surface of the substrate, and the conductive spring is disposed on the side of the substrate on which the first and second conductor patterns are located. The first and second conductor patterns are provided apart from each other and have a shape that protrudes on the opposite side of the first and second conductor patterns. When the pressing portion is pressed down, the shape of the conductive spring is reduced. The first and second conductor patterns are irreversibly reversed so as to be convex, and the conductive spring is in contact with both the first conductor pattern and the second conductor pattern in an inverted state, You may conduct.
According to this aspect, the first conductor pattern and the second conductor pattern can be irreversibly conducted with a simple configuration.

(4) In the above embodiment, the first conductor pattern and the second conductor pattern are formed on different surfaces of the substrate, respectively, and the conductive spring is one of the two end portions of the conductive spring. An end portion is connected to one of the first conductor pattern and the second conductor pattern, and before the pressing portion is pushed down, the other end portion of the conductive spring is connected to the substrate. It is spaced apart from the conductor pattern by being on the opposite side of the other conductor pattern of the first conductor pattern and the second conductor pattern, and after the pressing portion is pushed down, An end portion may move to the other conductor pattern side beyond the substrate, and the other end portion and the other conductor pattern may be electrically connected by an urging force of the conductive spring.
According to this aspect, the first conductor pattern and the second conductor pattern can be irreversibly conducted with a simple configuration.

First embodiment:
(1) Device configuration:
FIG. 1 is a schematic configuration diagram of a loss prevention system including a loss prevention tag 10 (hereinafter referred to as “tag 10”) including a wireless device 20 as an embodiment and a parent device 40 communicating with the tag 10. . The tag 10 includes a wireless device 20 and an attachment portion 23 for attaching the wireless device 20 to another article. The wireless device 20 incorporates a wireless communication circuit and a battery, which will be described later, and is sealed by a waterproof case 11. In the present embodiment, the attachment portion 23 is integrally formed in the waterproof case 11, and an opening 21 provided in a part of the wireless device 20 and a notch extending from the opening 21 to the outer edge of the waterproof case 11. 22. Note that the attachment portion 23 may be configured by a member separate from the wireless device 20 such as a carabiner, a string, or a binding band that passes through the opening 21. In this case, the notch 22 may not be present. That is, the attachment part 23 should just have the structure which can attach the radio | wireless apparatus 20 to another article | item easily. The tag 10 is attached to an object such as a wallet, a key, a bag, and an umbrella by the attachment portion 23. The tag 10 has a pressing unit 12. The pressing unit 12 is formed so that a part of the waterproof case 11 can be deformed, and functions as a button for starting power supply to the wireless communication circuit of the wireless device 20. The pressing unit 12 is pressed by the user of the tag 10. The mechanism for starting the operation of the tag 10 using the pressing unit 12 will be described in detail later.

  The parent device 40 is a device for confirming the position of the tag 10, and a portable device such as a smartphone or a tablet can be used as the parent device 40. The base unit 40 has a display 41. The display 41 is a display device having an input function, and is used for displaying and inputting various information to the user. The loss prevention system using the tag 10 is realized in combination with application software that operates on the parent device 40. The configuration of the wireless device 20 and the parent device 40 of this loss prevention system and the outline of the operation will be described below.

  FIG. 2 is an example of a circuit configuration of the wireless device 20 and the parent device 40. The wireless device 20 includes a battery 100, a wireless communication circuit 110, and a power supply device 120. The power supply device 120 includes a pressing unit 12, a protrusion 13, and a power supply path 121. In the present embodiment, for example, a button battery such as CR2025 or a sheet battery such as CP124920 can be used as the battery 100. The wireless communication circuit 110 has an antenna 111 and transmits a beacon at regular intervals after energization is started. The wireless communication circuit 110 and the power supply path 121 of the power supply device 120 are connected in series. When the power supply path 121 is in a non-conduction state (also referred to as “non-conduction”), power is supplied to the wireless communication circuit 110. However, when the power supply path 121 is in a conductive state (also referred to as “conductive”), power is supplied to the wireless communication circuit 110.

  The power supply path 121 includes a conductive spring 122 and first and second conductor patterns 123 and 124. A protrusion 13 is provided below the pressing portion 12 (inside the case 11), and a conductive spring 122 is disposed on the edge side of the protrusion. The conductive spring 122 and the first and second conductor patterns 123 and 124 are connected in series to provide the power supply path 121. In the state where the battery and the wireless communication circuit 110 are assembled in the case 11, the conductive spring 122 is separated from the first and second conductor patterns 123 and 124, and the power supply path 121. Is in a non-conductive state. By acting from the outside of the case 11, specifically, by pressing down the pressing portion 12, the protrusion 13 presses the conductive spring 122, and the conductive spring 122 contacts the first and second conductor patterns 123 and 124. The power supply path 121 is irreversibly rendered conductive. That is, power is not supplied to the wireless communication circuit 110 before the pressing unit 12 is pressed down. On the other hand, once the pressing unit 12 is pressed down, power can be supplied to the wireless communication circuit 110. A specific configuration of the power supply device 120 will be described later.

  The parent device 40 includes a display 41, a CPU 42, a wireless communication circuit 43, an antenna 44, a GNS reception circuit 45, and a memory 46. The wireless communication circuit 43 is a wireless communication circuit for communicating with the wireless device 20 of the tag 10 and the like. The GNS receiving circuit 45 receives radio waves from the GNS of the Global Navigation Satellite System, and acquires time and position. When the wireless communication circuit 43 receives a beacon from the wireless device 20 of the tag 10, the CPU 42 acquires the time and position (the position of the parent device 40) from the GNS receiving circuit 45 and writes it in the memory 46. The memory 46 is used not only for storing programs such as application software, but also for storing the time and position when a beacon is received.

  FIG. 3 is a flowchart up to the start of use of the tag 10 in the loss prevention system. In step S <b> 100, the user of the tag 10 presses down the pressing unit 12 to start supplying power to the wireless communication circuit 110 of the wireless device 20. Thereby, the radio | wireless communication circuit 110 transmits a beacon for every predetermined period. Details of this operation will be described later. In step S110, the user of the tag 10 activates the application software of the parent device 40 and performs pairing between the wireless device 20 and the parent device 40. The user registers the pairing information of the wireless device 20 in the parent device 40 using the parent device 40. Thereby, the main | base station 40 comes to be able to judge the correspondence between which beacon and which tag 10 respond | correspond. In step S120, the user attaches the tag 10 to the article. The user may perform step S120 for attaching the tag 10 to the article before steps S100 and S110.

  FIG. 4 is an operation flowchart of application software in the parent device 40. In step S200, the user starts the application software of the tag loss prevention system. In step S210, the master unit receives a beacon from the wireless device 20 of the tag 10. In step S220, when receiving a beacon from the wireless device 20 of the tag 10, the CPU 42 of the parent device 40 writes the time when the beacon is received and the position of the parent device 40 in the memory 46. The time and position can be acquired from the GNS receiving circuit 45. In step S230, the CPU 42 of the base unit 40 determines whether or not the beacon from the wireless device 20 of the tag 10 can be received every predetermined period. If the beacon cannot be received, the process proceeds to step S240 and the beacon is received. If completed, the process returns to step S210. In step S240, the CPU 42 of the parent device 40 displays the position of the parent device 40 when the beacon is last received on the display 41. For example, when the distance between the tag 10 and the parent device 40 increases, the parent device 40 may not be able to receive a beacon. That is, when the beacon cannot be received, there is a possibility that the article attached with the tag 10 is not in the vicinity of the parent device 40 and the user has lost or lost the article. Therefore, the CPU 42 of the parent device 40 displays the position of the parent device 40 on the display 41 when the beacon is last received on the display 41. At this time, the CPU 42 of the parent device 40 may notify the user that the beacon cannot be received by voice or the like. Further, the CPU 42 of the parent device 40 may display the position stored in the memory 46 on the display 41 in time series. The article to which the tag 10 is attached is located in the vicinity of the route from the position of the main unit 40 when the beacon is last received to the position (current position) of the main unit 40 when the beacon is finally received on the display 41. There is a high possibility. The user can search for an article to which the tag 10 is attached using the position information displayed on the display 41 as a clue. If the beacon can be received again after the beacon cannot be received, the CPU 42 of the parent device 40 may delete the position displayed on the display 41 so as not to be displayed.

(2) Configuration of power supply device:
FIG. 5 is an explanatory diagram showing a specific configuration of the power supply apparatus 120. The power supply device 120 includes a pressing portion 12, a protrusion 13, a substrate 14, an insulating substrate 16, a conductive spring 122, and first and second conductor patterns 123 and 124. The substrate 14 has an opening 141, and the first and second conductor patterns 123 and 124 are provided on the substrate 14 with the opening 141 interposed therebetween, but are not in contact with each other. The insulating substrate 16 is provided between the substrate 14 and the pressing portion 12, and a conductive spring 122 is provided. In the initial state before the pressing part 12 is pushed down, the conductive spring 122 has a shape in which the protrusion 13 side is convex, and is not in contact with both the first and second conductor patterns 123 and 124. The first and second conductor patterns 123 and 124 are electrically non-conductive.

  When the pressing portion 12 is pushed down, the protrusion 13 pushes down the convex top of the conductive spring 122 and reverses the convex direction of the conductive spring 122 as shown by the broken line in FIG. As a result, the conductive spring 122 comes into contact with the first and second conductor patterns 123 and 124 by the biasing force, and the first conductor pattern 123 and the second conductor pattern 124 are brought into a conductive state via the conductive spring 122. Become. The conductive spring 122 has two stable shapes, a convex shape upward and a convex shape downward. In addition, since the structure for returning the convex direction of the conductive spring 122 is not provided, the conductive spring 122 maintains a state in which the first conductive pattern 123 and the second conductive pattern 124 are in contact with each other. It does not return to the state before 12 is pushed down.

  As described above, according to the first embodiment, the power supply device 120 includes the conductive spring 122 that can be electrically connected to the first conductor pattern 123 and the second conductor pattern 124. When the pressing portion 12 is pushed down from the outside of the waterproof case 11, the convex direction of the conductive spring 122 is reversed, and the first conductor pattern 123 and the second conductor pattern 124 are in a conductive state via the conductive spring 122. It becomes. That is, the power supply path 121 (FIG. 2) is in a conductive state, and power is supplied to the wireless communication circuit 110. That is, with such a simple configuration, power is not supplied to the wireless communication circuit 110 until the start of use of the tag 10, and thereafter, power can be supplied to the wireless communication circuit 110. In other words, the wireless communication circuit can be used after the explicit processing (after the push-down unit 12 is pushed down) that the battery power can be suppressed during the period from the shipment to the start of use, for example, in the distribution inventory, and the purchaser starts using the product. Since the battery power supply to 110 is started, it is easy to guarantee the usage period of the tag 10.

  In addition, since the change in the convex direction of the conductive spring 122 is an irreversible change, the convex direction of the conductive spring 122 faces the pressing portion 12 side, and between the first conductor pattern 123 and the second conductor pattern 124. Never returns to non-conduction. That is, after power is supplied to the wireless communication circuit 110, the supply of power to the wireless communication circuit 110 is stopped by the user's action, and the beacon transmission is not stopped. That is, it does not happen that the tag 10 is accidentally turned off during use and becomes useless when it is important.

  In the above embodiment, the operation of changing the direction of the conductive spring 122 by pushing down the pressing portion 12 is performed inside the waterproof case 11, so that the waterproofness of the tag 10 is not impaired. In this embodiment, since the battery 100 is also embedded in the waterproof case 11 and cannot be replaced, the waterproof property can be enhanced.

  In the above embodiment, the conductive spring 122 is made of a conductive metal. However, the conductive spring 122 may be formed of a conductive material such as a resin with a metal foil attached to the conductive patterns 123 and 124 side. That is, you may form by the resin-made base material and the metal layer of the surface.

Second embodiment:
FIG. 6 is an explanatory diagram illustrating a specific configuration of the power supply device 120 according to the second embodiment. In the second embodiment, the power supply device 120 includes a pressing portion 12, a protrusion 13, a substrate 14, a conductive spring 122, and first and second conductor patterns 123 and 124. The substrate 14 has an opening 141, and the first and second conductor patterns 123 and 124 are provided on opposite surfaces of the substrate 14 with the opening 141 interposed therebetween, but are not in contact with each other. . One end 125 of the conductive spring 122 is fixed in contact with the second conductor pattern 124. The other end 126 of the conductive spring 122 is not in contact with the first conductor pattern 123. The other end 126 is a free end that can move freely. The substantially center of the conductive spring 122 is convex toward the protrusion 13.

  When the pressing portion 12 is pushed down, the protrusion 13 pushes down substantially the center of the conductive spring 122, and the other end 126 of the conductive spring 122 exceeds the substrate 14 as shown by the broken line in FIG. Move to the opposite side. As a result, the conductive spring 122 is in contact with the first conductor pattern 123 and is electrically conducted from the first conductor pattern 123 to the second conductor pattern 124. That is, the power supply path 121 (FIG. 2) is in a conductive state, and power can be supplied to the wireless communication circuit 110. In addition, since the structure for returning the position of the other end 126 of the conductive spring 122 is not provided, the conductive spring 122 does not return to the state before the pressing portion 12 is pushed down. Also in this embodiment, the same effect as in the first embodiment is obtained, and with a simple configuration, power is not supplied to the wireless communication circuit 110 until the use of the tag 10 is started, and thereafter, power is supplied to the wireless communication circuit 110. Can supply.

Third embodiment:
FIG. 7 is an explanatory diagram illustrating a specific configuration of the power supply device 120 according to the third embodiment. The difference from the second embodiment shown in FIG. 6 is that the first and second conductor patterns 123 and 124 are formed on the same surface of the substrate 14. Also in this embodiment, when the pressing portion 12 is pushed down, the protrusion 13 pushes down almost the center of the conductive spring 122, and the other end 126 of the conductive spring 122 exceeds the substrate 14 as shown by a broken line in FIG. Then, it moves to the surface opposite to the substrate 14. As a result, the conductive spring 122 is in contact with the first conductor pattern 123 and is electrically conducted from the first conductor pattern 123 to the second conductor pattern 124. That is, the power supply path 121 (FIG. 2) is in a conductive state, and power can be supplied to the wireless communication circuit 110. This configuration also has the same effect as that of the first embodiment, and with a simple configuration, power is not supplied to the wireless communication circuit 110 until the start of use of the tag 10, and then power is supplied to the wireless communication circuit 110. Can supply.

  In the second and third embodiments shown in FIG. 6 and FIG. 7, the conductive spring 122 is made to be convex on the pressing portion 12 and projection 13 side. However, the conductive spring 122 has a substantially flat shape. Also good. When the shape of the conductive spring 122 is a shape in which the pressing portion 12 and the protrusion 13 are convex, the size of the protrusion 13 can be reduced.

  Also in the second and third embodiments, similarly to the first embodiment, the conductive spring 122 may be formed of a resin base material and a metal layer on the surface thereof.

Other embodiment 1:
In the first to third embodiments shown in FIGS. 5 to 7, the convex portion of the conductive spring 122 and the position of the other end portion 126 are changed by pushing down the pressing portion 12. Instead of using the conductive spring 122, conduction and non-conduction between the first and second conductor patterns 123 and 124 may be controlled by a conductor formed of a shape memory alloy. For example, the shape memory alloy conductor is molded so as not to contact the first and second conductor patterns 123 and 124, stored at a low temperature, and returned to room temperature when in use. The second conductor patterns 123 and 124 may be brought into contact with each other, and the shape memory alloy conductor is molded and stored so as not to contact the first and second conductor patterns 123 and 124, and temporarily high in use. By doing so, the shape memory alloy conductor may be brought into contact with the first and second conductor patterns 123 and 124. Even with such a configuration, power is not supplied to the wireless communication circuit 110 until the use of the tag 10 is started, and thereafter, power can be supplied to the wireless communication circuit 110.

Other embodiment 2:
FIG. 8 is an explanatory diagram illustrating a wireless device 20 according to another embodiment. In this embodiment, a semiconductor switch 150 is provided in parallel with the conductive spring 122. As the configurations of the pressing portion 12, the protruding portion 13, the conductive spring 122, and the first and second conductor patterns 123 and 124, the configurations already described can be employed. In the example shown in FIG. 8, the semiconductor switch 150 is a Pch MOS field effect transistor. The gate (node N5) of the semiconductor switch 150 is connected to the node N4 on the power supply side via the resistor 151. The gate of the semiconductor switch 150 is connected to the ground-side node N6 through a conductor 152 formed of a conductive resin. The conductor 152 passes through a cutout portion 153 provided so as to be cut out from the waterproof case 11. In a state before the cutting unit 153 is cut, the potential of the gate (node N5) of the semiconductor switch 150 is the ground potential, and the semiconductor switch 150 is on. Accordingly, power is supplied to the wireless communication circuit 110. Therefore, the wireless device 20 can be inspected. When the cut portion 153 is cut, the conductor 152 is disconnected, the potential of the gate (node N5) of the semiconductor switch 150 becomes the power supply potential, and the semiconductor switch 150 is turned off. In this state, since power is not supplied to the wireless communication circuit 110, the power of the battery 100 is not consumed. That is, in this embodiment, the power consumption until the start of use of the tag 10 can be suppressed by cutting the cutting unit 153 after the inspection of the wireless device 20. Note that when the conductor 152 is cut off, the resistance value may be increased even if the conductor 152 is not completely turned off. In this case, the semiconductor switch 150 becomes non-conductive if the gate potential VGS of the semiconductor switch 150 becomes smaller than the threshold value due to the resistance division ratio between the resistor 151 and the conductive resin conductor 152 that has been cut off and partially left. Note that the use of the tag 10 is started by depressing the pressing unit 12 as in the above embodiments.

  The present invention is not limited to the above-described embodiment, and can be realized with various configurations without departing from the spirit of the present invention. For example, the technical features of the embodiments corresponding to the technical features in each embodiment described in the summary section of the invention are intended to solve part or all of the above-described problems, or part of the above-described effects. Or, in order to achieve the whole, it is possible to replace or combine as appropriate. Further, if the technical feature is not described as essential in the present specification, it can be deleted as appropriate.
