DETAILED DESCRIPTION OF THE INVENTION

[0009] A communication device and a charging station according to an embodiment will be described below with reference to the drawings.

[0010] (One embodiment) A communication device according to one embodiment is shown in Fig. 1. The communication device 1 is a communication device (sensor device) used in a monitoring system capable of tracking the whereabouts of children in, for example, a nursery school or kindergarten. In the above monitoring system, the communication device 1 is used as a "child sensor device" that is attached to the clothing of a child, or as a "teacher sensor device" that is attached to the clothing of a teacher. The communication device 1 used as a "child sensor device" has a position information detection unit 32 (described later) that can detect the position information of the communication device 1 attached to the child. The position information detected by the position information detection unit 32 is transmitted to a server device or the like via a network. Display information generated based on the position information transmitted to the server device is displayed on a terminal device carried by the teacher or the like. This allows the teacher to grasp (monitor) the whereabouts of the child.

[0011] As shown in FIG. 1 , the communication device 1 includes a main body 10, a communication unit 31, a main body-side suction member 40, a cover 50, and a cover-side suction member 70.

The communication unit 31 has, for example, a SIM card 311, and is capable of communicating with a server device or the like by connecting to a network via a telephone line of a mobile phone company or the like. Here, at least the communication unit 31 of the communication device 1 used as a "kindergartener sensor device" has the SIM card 311. On the other hand, the communication unit 31 of the communication device 1 used as a "teacher sensor device" does not need to have the SIM card 311.

[0012] The communication unit 31 has, for example, a wireless LAN module. This wireless LAN module can transmit and receive, for example, Wi-Fi (registered trademark) signals (radio waves), which is one of the wireless LAN communication methods. Here, at least the communication unit 31 of the communication device 1 used as the "teacher sensor device" can transmit Wi-Fi signals (radio waves), and the communication unit 31 of the communication device 1 used as the "kindergartener sensor device" can receive Wi-Fi signals (radio waves) transmitted from the "teacher sensor device." Here, at least the communication unit 31 of the communication device 1 used as the "teacher sensor device" has a wireless LAN module. On the other hand, the communication unit 31 of the communication device 1 used as the "kindergartener sensor device" does not need to have a wireless LAN module as long as it can receive Wi-Fi signals (radio waves) transmitted from the "teacher sensor device."

[0013] The main body-side attraction member 40 is provided on the main body 10. The cover 50 is provided on one side of the main body 10. The cover-side attraction member 72 is provided on the cover 50 and can be attracted to the main body-side attraction member 40 by magnetic attraction force.

[0014] The communication device 1 further includes a position information detection unit 32. The position information detection unit 32 is provided in the main body 10 and is capable of detecting position information of the main body 10.

Here, at least the communication device 1 used as a "sensor device for kindergarteners" includes the position information detection unit 32. On the other hand, the communication device 1 used as a "sensor device for teachers" does not need to include the position information detection unit 32.

[0015] The communication device 1 further includes a battery 35 and a processing unit 30. The battery 35 is a rechargeable secondary battery such as a lithium ion secondary battery. The battery 35 can supply power to the communication unit 31, the position information detection unit 32, the processing unit 30, etc. The processing unit 30 is a calculation device such as a microcomputer, and can process signals (information) transmitted between the communication unit 31, the position information detection unit 32, the battery 35, etc.

[0016] The configuration of the communication device 1 will be described in detail below. As shown in FIG. 2, the main body 10 has a main body base 11, a main body protrusion 12, an adsorption member hole 13, etc. The main body base 11 has a first main body base 111 and a second main body base 112. The first main body base 111 is formed of, for example, a resin, in the shape of a curved disk with one surface. The second main body base 112 is formed of, for example, a resin, in the shape of a flat disk with one surface. The main body base 11 is formed by joining the other surfaces of the first main body base 111 and the second main body base 112 to each other. A storage space 110 is formed between the first main body base 111 and the second main body base 112. The storage space 110 houses a part of the communication unit 31, the position information detection unit 32, the battery 35, the processing unit 30, etc.

[0017] The main body protrusion 12 is formed integrally with the main body base 11 using, for example, resin. The main body protrusion 12 is formed so as to protrude from the surface of the second main body base 112 of the main body base 11 opposite the first main body base 111 toward the opposite side of the first main body base 111. The main body protrusion 12 has a protrusion base 121 and an arcuate extension 122. The protrusion base 121 is formed in a rectangular plate shape such that the protrusion direction from the main body base 11 corresponds to the plate thickness direction. The arcuate extension 122 is formed so as to extend from the outer peripheral walls of two of the four sides of the protrusion base 121 along the longitudinal direction toward the outside of the protrusion base 121. An arcuate wall surface 123 is formed on the side of the arcuate extension 122 opposite the protrusion base 121. The arcuate wall surface 123 is formed in a curved shape so as to follow a portion of the circumferential direction of the imaginary cylindrical surface VT1 (see FIG. 2(A)).

[0018] The suction member hole 13 is formed so as to be recessed in a circular (cylindrical) shape from the surface of the second main body base 112 of the main body base 11 opposite to the first main body base 111 toward the first main body base 111. Two suction member holes 13 are formed in the second main body base 112 so that their centers approximately coincide with the center of the imaginary cylindrical surface VT1.

[0019] The main body 10 further includes a charging unit 21, charging terminals 22, magnets 23, 24, a SIM card cover 25, an LED indicator light 26, a strap hole 27, and a screw hole 28. The charging unit 21 is formed near one of the two short sides of the protrusion base 121 (see FIG. 2(A)). Four charging terminals 22 are arranged in a row on the charging unit 21 and are electrically connected to the battery 35 via the processing unit 30. This allows the battery 35 to be charged by supplying power from the charging terminals 22. The magnets 23 and 24 are provided inside the charging unit 21 on both sides of the direction in which the row of charging terminals 22 is arranged.

[0020] The SIM card cover 25 is formed, for example, from resin in the shape of a rectangular plate, and is provided so as to cover a recessed card storage section 251 formed in the center of the protrusion base 121. A SIM card 311 that constitutes a part of the communication section 31 is stored in the card storage section 251.

[0021] As shown in FIG. 1, the LED indicator light 26 is provided on the outer edge of the first main body base 111, and can indicate (inform) the outside of the charging status, operating status, etc. of the communication device 1 by lighting up or flashing in red, green, blue, etc.

[0022] The strap holes 27 are formed to penetrate the first main body base 111 and the second main body base 112 in the thickness direction. A string-like member such as a strap can be attached to the strap holes 27.

[0023] The screw holes 28 are formed at four locations on the outer edge of the surface of the second main body base 112 opposite to the first main body base 111. The screw holes 28 are provided with screws for joining the first main body base 111 and the second main body base 112 together.

[0024] The main body-side attraction member 40 is a permanent magnet such as a neodymium magnet, and is formed in a disk shape. The outer edges of both end faces of the main body-side attraction member 40 are chamfered into a curved shape. As shown in FIG. 2 , the main body-side attraction member 40 is provided by fitting and / or adhering to the inner circumferential walls of attraction member holes 13 formed in two locations on the main body 10. A retaining portion 131 is formed in the attraction member hole 13. The retaining portion 131 is formed in an annular shape so as to extend radially inward from the inner circumferential wall of the attraction member hole 13 at the end opposite the first main body base 111. The retaining portion 131 engages the outer edge (corner) of one end face of the main body-side attraction member 40, thereby preventing the main body-side attraction member 40 from coming off (falling off) from the attraction member hole 13. Here, for convenience, one of the two main body side suction members 40 provided in the two suction member holes 13 will be referred to as a main body side suction member 41, and the other will be referred to as a main body side suction member .

[0025] The cover 50 is formed, for example, from resin and includes a cover plate 51, a cover tube 52, and a cover lid 53. The cover plate 51 is formed in a disk shape. The cover tube 52 is formed integrally with the cover plate 51 so as to extend cylindrically from one side of the cover plate 51. The space inside the cover tube 52 is connected (opens) to the other side of the cover plate 51. The cover lid 53 is formed in a disk shape and is provided to cover the side of the cover plate 51 opposite the cover tube 52. The space inside the cover tube 52 that opens to the other side of the cover plate 51 is closed by the cover lid 53. The cover 50 is provided on the side of the second main body base 112 opposite the first main body base 111. Two cover tubes 52 are formed on the cover 50 so that their centers approximately coincide with the centers of the imaginary cylindrical surface VT1 and the suction member hole 13. A charging opening 61 is formed in the cover 50. The charging opening 61 is formed so as to penetrate the cover plate 51 and the cover lid 53 at a position corresponding to the charging unit 21 of the main body 10.

[0026] The cover-side attraction member 70 is a permanent magnet, such as a neodymium magnet, and is formed in a disk shape. The outer edges of both end faces of the cover-side attraction member 70 are chamfered into a curved shape. The cover-side attraction member 70 is provided by fitting and / or adhering to the inner circumferential walls of the cover tubular portion 52 formed at two locations on the cover 50. A retaining portion 521 is formed on the cover tubular portion 52. The retaining portion 521 is formed in an annular shape so as to extend radially inward from the inner circumferential wall of the end of the cover tubular portion 52 opposite the cover plate portion 51. The retaining portion 521 engages the outer edge (corner) of one end face of the cover-side attraction member 70, thereby preventing the cover-side attraction member 70 from coming off (falling off) from the cover tubular portion 52. Note that the cover-side attraction member 70 is inserted into the cover tubular portion 52 from the end (opening) of the cover tubular portion 52 facing the cover lid portion 53 before the cover lid portion 53 is attached to the cover plate portion 51. Here, for convenience, one of the two cover-side attracting members 70 provided on the two cover tubular portions 52 will be referred to as a cover-side attracting member 71 and the other as a cover-side attracting member 72.

[0027] The end face of the body-side attraction member 41 facing the cover 50 is magnetized to an S pole, and the end face opposite the cover 50 is magnetized to an N pole. The end face of the cover-side attraction member 71 facing the body 10 is magnetized to an N pole, and the end face opposite the body 10 is magnetized to an S pole. The end face of the body-side attraction member 42 facing the cover 50 is magnetized to an N pole, and the end face opposite the cover 50 is magnetized to an S pole. The end face of the cover-side attraction member 72 facing the body 10 is magnetized to an S pole, and the end face opposite the body 10 is magnetized to an N pole. Therefore, the body-side attraction member 41 and the cover-side attraction member 71, and the body-side attraction member 42 and the cover-side attraction member 72 can be attracted to each other by their mutual magnetic attraction forces (see FIG. 2(B)). By making the magnetic polarities of the end faces of the main body side attracting member 41 and the main body side attracting member 42 on the cover 50 side different, it is possible to prevent the cover 50 from being attracted to the main body 10 in the wrong direction (rotational position).

[0028] By placing the main body 10 on the front side of the fabric of the garment 2 and the cover 50 on the back side of the fabric (see FIG. 2(C)), and aligning the positions of the main body-side attracting member 40 and the cover-side attracting member 70, the communication device 1 can be easily attached to the garment 2 by sandwiching the garment 2 between the main body 10 and the cover 50 due to the magnetic attraction between the main body-side attracting member 40 and the cover-side attracting member 70 (see FIG. 2(D)). When the garment 2 is sandwiched between the main body 10 and the cover 50, a part of the garment 2 is positioned in the arc-shaped space between the arc-shaped wall surface 123 and the outer peripheral wall of the cover tubular portion 52 (see FIG. 2(D)). This makes it possible to prevent the communication device 1 from shifting position relative to the garment 2.

[0029] Next, a method for attaching the communication device 1 to the clothing 2 will be described. First, the main body 10 and the cover 50 are separated by pulling them apart against the magnetic attraction between the main body-side attraction member 40 and the cover-side attraction member 70 (see FIG. 3(A)). Next, the main body 10 is placed on the front side of the fabric of the garment 2, and the cover 50 is placed on the back side of the fabric (see FIG. 3(B)). Next, while aligning the positions of the main body-side attraction member 41 and the cover-side attraction member 71, and the positions of the main body-side attraction member 42 and the cover-side attraction member 72, the main body 10 and the cover 50 are brought closer together, and the garment 2 is sandwiched between the main body 10 and the cover 50 (see FIGS. 3(C) and 3(D)). At this time, the garment 2 is firmly sandwiched between the main body 10 and the cover 50 due to the magnetic attraction between the main body-side attraction member 40 and the cover-side attraction member 70.

[0030] Next, a description will be given of charging the communication device 1. In this embodiment, charging via a charging cable 80 and charging via a charging station 90 will be described. Charging using charging cable 80 will be described below. As shown in FIG. 4(A), charging cable 80 includes a cable portion 801, a magnetically attracted terminal 81, a charging terminal 82, a magnet 83, and a magnet 84. Cable portion 801 is a conductor capable of supplying power. Magnetically attracted terminal 81 is provided at one end of cable portion 801. Four charging terminals 82 are provided on magnetically attracted terminal 81 in a row and are electrically connected to cable portion 801. Magnets 83 and 84 are provided on magnetically attracted terminal 81 on both sides of the row of charging terminals 82.

[0031] The end faces of magnets 23 and 24 provided on charging unit 21 of main body 10 opposite main body base 11 are magnetized to the south and north poles, respectively. The end faces of magnets 83 and 84 exposed from magnetically attracting terminal 81 of charging cable 80 are magnetized to the north and south poles, respectively. Therefore, magnets 23 and 83, and magnets 24 and 84 can be attracted to each other by their mutual magnetic attraction forces.

[0032] When magnetically attracted terminal 81 is brought close to charging unit 21 of main body 10, the magnetic attractive force between magnets 23 and 83, and between magnets 24 and 84, attracts magnetically attracted terminal 81 and charging unit 21 via charging opening 61. This electrically connects charging terminal 22 on main body 10 to charging terminal 82 on charging cable 80. By making the end faces of magnets 83 and 84 exposed from magnetically attracted terminal 81 different in magnetic polarity, magnetic attractive terminal 81 is prevented from being attracted to charging unit 21 in the wrong direction.

[0033] With the magnetically attracted terminal 81 and the charging unit 21 attracted to each other, power can be supplied from the other end of the cable unit 801 to charge the battery 35 of the communication device 1. As shown in FIG. 4(B), while the communication device 1 is being charged, the LED indicator light 26 lights up, for example, in red.

[0034] Charging using the charging station 90 will now be described. Japanese Patent Application Laid-Open Publication No. 2018-175489 discloses a communication device that can be charged by contactless power transmission. In a nursery school or the like where communication devices need to be attached to many children as in the present embodiment, charging all the communication devices one by one takes time and is inefficient.

[0035] An object of the present invention is to provide a charging station capable of efficiently charging a plurality of communication devices.

[0036] As shown in FIG. 5A , the charging station 90 includes a station main body 91, a mounting recess 92, a charging unit 93, and a charging terminal 94. The station main body 91 is formed, for example, from resin into a rectangular plate shape. The mounting recess 92 is formed so as to be recessed in a circular (cylindrical) shape from one surface (top surface) of the station main body 91. The inner diameter of the mounting recess 92 is set to be slightly larger than the outer diameter of the main body 10 and the cover 50 of the communication device 1. In this embodiment, a total of 12 mounting recesses 92 are formed, for example, three in the vertical direction and four in the horizontal direction of the station main body 91. The charging unit 93 is provided to protrude from the bottom surface of the mounting recess 92. The shape of the charging unit 93 corresponds to the shape of the charging opening 61 of the cover 50 of the communication device 1. Four charging terminals 94 are provided in the charging unit 93, arranged in a row, and are electrically connected to a power supply unit (not shown).

[0037] As shown in FIG. 5(B), the communication device 1 can be charged by placing it in the placement recess 92 of the charging station 90. When the communication device 1 is placed in the placement recess 92, the charging section 93 fits into the charging opening 61 of the cover 50, electrically connecting the charging terminal 94 of the charging station 90 with the charging terminal 22 of the communication device 1, and charging begins. FIG. 5(B) shows a state in which three communication devices 1 are being charged. The charging station 90 of this embodiment can charge up to 12 communication devices 1 at once. In this way, the charging station 90 can efficiently charge multiple communication devices 1.

[0038] As described above, in the present embodiment of "Disclosure 1," the communication unit 31 is provided on the main body 10. The main body-side attraction member 40 is provided on the main body 10. The cover 50 is provided on one side of the main body 10. The cover-side attraction member 72 is provided on the cover 50 and can be attracted to the main body-side attraction member 40 by magnetic attraction force.

[0039] With the above configuration, for example, by placing the main body 10 on the front side of a fabric such as clothing 2 and the cover 50 on the back side of the fabric, and aligning the positions of the main body-side attraction member 40 and the cover-side attraction member 70, the communication device 1 can be easily attached to the clothing 2 by sandwiching the clothing 2 between the main body 10 and the cover 50 due to the magnetic attraction force between the main body-side attraction member 40 and the cover-side attraction member 70. In addition, the communication device 1 can be easily removed from the clothing 2 by simply pulling the main body 10 and the cover 50 apart against the magnetic attraction force between the main body-side attraction member 40 and the cover-side attraction member 70.

[0040] In addition, in this embodiment of "Disclosure 2," at least one of the main body-side attraction member 40 and the cover-side attraction member 70 is a magnet. In this embodiment, both the main body-side attraction member 40 and the cover-side attraction member 70 are magnets 24. This increases the magnetic attraction force between the main body-side attraction member 40 and the cover-side attraction member 70, allowing the communication device 1 to be firmly attached to clothing 2, etc.

[0041] In addition, in the present embodiment of "Disclosure 3," a plurality of main body-side attracting members 40 are provided on the main body 10. A plurality of cover-side attracting members 70 are provided on the cover 50. Therefore, the communication device 1 can be firmly attached to clothing 2 or the like.

[0042] In addition, in the present embodiment of "Disclosure 4," two main body side suction members 40 are provided on one surface of the main body 10, sandwiching the center between them. This allows the communication device 1 to be firmly attached to the clothing 2 or the like in a balanced manner.

[0043] Furthermore, this embodiment of "Disclosure 5" further includes a location information detection unit 32. The location information detection unit 32 is capable of detecting the location information of the main body 10. Therefore, the communication device 1 can be used as a "sensor device for kindergarteners" for grasping (monitoring) the whereabouts of kindergarteners in a monitoring system.

[0044] (Other embodiments) In the above-described embodiment, an example has been shown in which the magnetic polarities of the end faces of the two main body-side attracting members 40 facing the cover 50 are different, and the magnetic polarities of the end faces of the two cover-side attracting members 70 facing the main body 10 are different. In contrast to this, in other embodiments, the magnetic polarities of the end faces of the two main body-side attracting members 40 facing the cover 50 may be the same, and the magnetic polarities of the end faces of the two cover-side attracting members 70 facing the main body 10 may be the same.

[0045] In other embodiments, one or three or more main body side suction members 40 and cover side suction members 70 may be provided for the main body 10 and the cover 50, respectively.

[0046] In the above-described embodiment, an example was shown in which both the main body-side attracting member 40 and the cover-side attracting member 70 were magnets. However, in other embodiments, one of the main body-side attracting member 40 and the cover-side attracting member 70 may be made of a magnet (hard magnetic material), and the other may be made of a soft magnetic material such as iron that is attracted by the magnetic attraction force of the magnet.

[0047] In the above-described embodiment, the magnetic polarities of the end faces of the two magnets (23, 24) provided in the charging unit 21 of the main body 10 are different, and the magnetic polarities of the end faces of the two magnets (83, 84) provided in the magnetically adsorbed terminal 81 of the charging cable 80 are different. In contrast to this, in other embodiments, the magnetic polarities of the end faces of the two magnets (23, 24) provided in the charging unit 21 of the main body 10 may be the same, and the magnetic polarities of the end faces of the two magnets (83, 84) provided in the magnetically adsorbed terminal 81 of the charging cable 80 may be the same.

[0048] In another embodiment, a magnet (hard magnetic material) or a soft magnetic material such as iron that can be attracted to magnet 23 or magnet 24 provided in charging unit 21 of main body 10 may be provided in charging unit 93 of charging station 90.
