Since the plurality of charging coils 67 are arranged close to each other in the height direction of the receiving portion 61B, interference occurs in the magnetic field generated by each of the charging coils 67, and charging efficiency to the ring-shaped device 1 is increased. Becomes worse.
Therefore, in the present modification, as described above, a coil formed by connecting the spiral coil 67a is used as the charging coil 67, and the charging coil 67 is radially outward from the center of the receiving portion 61B (in FIG. 25, (Shown by arrow B) is configured to generate a magnetic field so as to suppress interference of the magnetic field in the height direction of the receiving portion 61B. Thereby, it becomes possible to charge several ring-shaped apparatus 1A-1C simultaneously, maintaining charging efficiency.
Further, by making the frame 12 of the ring-shaped device 1 into a polygonal shape, the circumferential direction of the receiving portion 61 </ b> B between the coil 19 built in the ring-shaped device 1 and the charging coil 67 built in the charging device 19. Positioning at is simplified.

  Next, a charging process for the plurality of ring-shaped devices 1A to 1C by the charging device 60 will be described. In this charging process, when the operation switch 62 is operated, the controller 70 determines the number of ring-shaped devices 1 placed on the receiving portion 61B, and charges those ring-shaped devices 1. Start. Specifically, as shown in FIG. 29, the controller 70 waits until the operation switch 62 is operated and turned ON (step S301: No). When the operation switch 62 is turned on (step S301: Yes), the controller 70 executes communication processing such as transmission of a charging start signal for requesting a response when starting charging to the ring-shaped device 1 ( Step S302), and waits until there is a reply from the ring-shaped device 1A that is first placed on the receiving portion 61B and located at the lower end of the receiving portion 61 (Step S303: No). When there is a response from the ring-shaped device 1A (step S303: Yes), the controller 70 determines how many ring-shaped devices 1 are placed on the receiving portion 61B in subsequent steps S304 and S305. It is determined whether there is a response from the ring devices 1B and 1C stacked on the ring device 1A. When the charging device 60 can charge three or more ring-shaped devices 1 at the same time, the controller 70 may be configured to confirm a response from each of the ring-shaped devices 1.

  When there is no response from the ring-shaped device 1B that overlaps the ring-shaped device 1A (step S304: No), it indicates that only the ring-shaped device 1A is placed on the receiving portion 61B. Therefore, the controller 70 confirms the ID (identification information) of the ring-shaped device 1A by wireless communication or the like with the ring-shaped device 1A (step S306), and the charging condition (charging time or charging) specified by the ID is confirmed. In accordance with the magnetic field intensity generated in the coil 67, etc., a magnetic field is generated in the charging coil 67 located at the lower end of the receiving portion 61B, and charging of the ring-shaped device 1A is started (step S307). And the controller 70 complete | finishes this process, when charge of the ring-shaped apparatus 1A is complete | finished (step S308: Yes). Note that the ID, the charging condition, and the corresponding relationship thereof are stored in advance in the controller 70 of the charging device 60, and can be simultaneously or individually applied to a plurality of ring-shaped devices 1 having different charging conditions. Can be charged.

  On the other hand, if there is a response from the ring-shaped devices 1A and 1B, but there is no response from the ring-shaped device 1C overlying the ring-shaped device 1B (step S305: No), the two rings of the ring-shaped devices 1A and 1B. This shows that the device 1 is placed on the receiving portion 61B. Therefore, the controller 70 confirms the ID (identification information) of the ring-shaped devices 1A and 1B (step S309), and first and second from the lower end of the receiving portion 61B according to the charging conditions for each of the ring-shaped devices 1A and 1B. A magnetic field is generated in the charging coil 67 and charging of these ring-shaped devices 1A and 1B is started (step S310). And the controller 70 complete | finishes this process, when charge of the ring-shaped apparatuses 1A and 1B is complete | finished (step S311: Yes).

  If there is a response from all of the ring-shaped devices 1A to 1C (step S305: Yes), it indicates that all of the ring-shaped devices 1A to 1C are placed on the receiving portion 61B. Therefore, the controller 70 confirms the IDs (identification information) of the ring-shaped devices 1A to 1B (step S312), and applies magnetic fields to all the charging coils 67 of the receiving unit 61B according to the charging conditions for each of the ring-shaped devices 1A to 1C. And the charging of these ring-shaped devices 1A to 1C is started (step S313). And the controller 70 complete | finishes this process, when charge of the ring-shaped apparatuses 1A-1C is complete | finished (step S314: Yes).

  A multi-stage weight switch may be provided on the bottom surface of the charging device 60, and charging may be started based on ON / OFF of the multi-stage weight switch. Specifically, in the charging device 60 configured to be able to charge a plurality of ring-shaped devices 1 simultaneously or individually, charging can be performed when, for example, a maximum of three ring-shaped devices 1 can be placed on the receiving portion 61B. A three-stage weight switch that is turned on in stages according to the number of ring-shaped devices 1 is provided on the bottom surface of the device 60. In this configuration, as shown in FIG. 30, when the three-stage weight switch is turned on (step S401: Yes), the controller 70 determines how many ring-shaped devices 1 are in the receiving portion 61B in steps S402 to S404. In order to determine whether it has been placed, it is determined how many stages the three-stage weight switch is turned on. That is, when the three-stage weight switch is turned on in three stages (step S402: Yes), it indicates that the three ring devices 1A to 1C are placed on the receiving portion 61B, and the two-stage ON is turned on. If this is the case (step S403: Yes), it indicates that the two ring-shaped devices 1A to 1B have been placed on the receiving portion 61B, and if only one stage is ON (step S404), the ring-shaped device It shows that only one 1A is placed on the receiving portion 61B. Therefore, in the subsequent steps S405 to S416, the controller 70 sets the number of ring-shaped devices 1 placed on the receiving portion 61B and the ID of each ring-shaped device 1 in the same manner as the above-described steps S306 to S312. Accordingly, the ring-shaped device 1 is charged, and after the charging is finished, this process is finished.

Further, instead of using the operation switch 62, as shown in FIG. 31, the controller 70 of the charging device 60 transmits a charging start signal each time a predetermined sampling time arrives (step S501: Yes) (step S502). And it is good also as a structure which detects that the 1 or several ring-shaped apparatus 1 was mounted in the receiving part 61B, and a structure which starts a charging process automatically irrespective of a user's operation. In addition, since the process in step S503 to S514 in FIG. 31 is the same as that of step S303 to 314 shown in FIG. 29 mentioned above, the description is abbreviate | omitted.
Thus, according to this modification, it is possible to charge a plurality of ring-shaped devices 1 simultaneously or individually. Further, when the receiving portion 61B is formed in a columnar shape so that the plurality of ring-shaped devices 1 having the same shape can be charged, a coil formed by connecting spiral coils as the charging coil 67 is used. In addition, since the charging coil 67 is arranged so that the magnetic field is generated radially outward from the central portion of the receiving portion 61B, it is possible to prevent the charging efficiency of the ring-shaped device 1 from being lowered.
In addition, as shown in FIG. 25, it becomes possible to make it easy to pass the ring-shaped apparatus 1 to the said receiving part 61B by reducing the diameter of the upper end of the receiving part 61B toward upper direction.

Specifically, as shown in FIG. 32, the charging device 60 has a GPS receiver 80 that receives a GPS signal transmitted from a GPS (Global Positioning System) satellite as a standard time acquisition unit that acquires a standard time. It is set as the structure to provide. Under this configuration, when the ring-shaped device 1 is placed on the receiving portion 61B, the controller 70 acquires an ID from the ring-shaped device 1 by wireless communication, and based on this ID, the ring-shaped device 1 It is determined whether or not it has a function of measuring time. If the ring-shaped device 1 has a timekeeping function, the controller 70 calculates a standard time based on the GPS signal received by the GPS receiver 80, and this standard time is ring-shaped by wireless communication. The time is transmitted to the device 1 to correct the time of the ring-shaped device 1.
Thus, according to this modification, since the charging device 60 corrects the time of the ring-shaped device 1, it is not necessary for the user to manually correct the time of the ring-shaped device 1, and the time adjustment is omitted. It becomes possible. In addition, it is good also as a structure using the standard radio wave receiver which receives the standard radio wave which shows standard time instead of the GPS receiving part 80 as a standard time acquisition means. This standard radio wave is transmitted from a transmitting station owned by the Communications Research Laboratory (CRL). In Japan, it is transmitted to Otakadoya and Mt. in Fukushima Prefecture and Mt. Hagane in Saga Prefecture. A place is provided.
