Then, using this induction electromagnetic field, various information related to the user's gate passage between the gate device 200 and the data carrier module 4, specifically, for example, data related to the user authentication process, the settlement process, etc. Are sent and received. Further, when the user passes through the gate, the data carrier module 4 is acquired by communication with the gate device 200 using the induction electromagnetic field formed between the data carrier side antenna coil 42 and the antenna coil 8. Various types of information are received by the clock unit 7. Thus, for example, by using the time counting function of the clock unit 7, the time management unit 7 performs time management based on the information acquired when the user passes through the gate, or the memory 76 of the clock unit 7 is stored. It is possible to back up the information acquired by the data carrier module 4 by using it.

In addition, the wristwatch 100 receives various types of information acquired by the data carrier module 4 through communication with the gate device 200 and the data carrier module when the user passes the gate by the antenna coil 8 provided in the watch case 2. Various kinds of information can be transmitted to the gate device 200 via the terminal 4. At this time, the antenna coil 8 forms an induction electromagnetic field with the data carrier side antenna coil 42 of the data carrier module 4 and uses the induction electromagnetic field to relate to the data carrier module 4 and the user passing through the gate. Since various types of information are transmitted and received, for example, when the data carrier module 4 and the antenna coil 8 are connected by wire to perform communication, no hole for wiring is required in the storage unit 5. The storage protection of the data carrier module 4 can be made more appropriate.

[Embodiment 3]
Hereinafter, the wristwatch 400 of the third embodiment will be described with reference to FIGS. 19 and 20.
Here, FIG. 19 is a diagram for explaining the arrangement of the data carrier module 4 in the storage unit 405 of the wristwatch 400 according to the third embodiment to which the present invention is applied. FIG. 20 is a diagram for explaining wireless communication between the wrist watch 400 and the gasoline meter 500.
The watch 400 according to the third embodiment is substantially the same as the first and second embodiments except for the mounting direction of the data carrier module 4, and therefore, the same components are denoted by the same reference numerals and the description thereof is omitted. Shall be omitted.

As shown in FIG. 19, the storage unit 405 is provided on the wristwatch 400 at the 12 o'clock side, and the data carrier module 4 is arranged so that the longitudinal direction of the bar antenna 342 is along the extending direction of the band member 403 in the storage unit 405. Is disposed and covered with a surface cover member 409.
That is, the data carrier module 4 includes, for example, a bar antenna 342 around which a data carrier antenna coil 3422 is wound along the longitudinal direction of the core 3421. The bar antenna 342 generates a magnetic field by generating magnetic flux from the end portion in the longitudinal direction of the core 3421 (see FIG. 20). In FIG. 20, the magnetic flux is indicated by a broken line. Accordingly, the direction of the formed magnetic field varies depending on the direction of the data carrier module 4 disposed in the wristwatch 400.

On the other hand, a loop antenna 501 is disposed in a reader / writer 502 mounted on a gasoline meter 500 disposed in, for example, a gas station as an external communication device constituting the RF-ID system. For example, the loop antenna 501 is provided upright along the extending direction of the surface on the user side of the gasoline meter 500. Then, an induction electromagnetic field is formed from the loop antenna 501 in accordance with the supply of power from a power supply unit (not shown) so that the magnetic flux passes inside the antenna (see FIG. 20).
Note that a control device (not shown) is connected to the reader / writer 502, and various functions as the gasoline meter 500 can be realized under the control of the control device.

  When the gasoline meter 500 is used, the data carrier module 4 of the wristwatch 400 and the gasoline meter 500 are arranged so that the longitudinal direction of the bar antenna 342 is substantially orthogonal to the loop antenna 501. That is, for example, as shown in FIG. 20, the wristwatch 400 is brought close to the reader / writer 502 of the gasoline meter 500 along the direction of arrow A, and the longitudinal direction of the bar antenna 342 of the wristwatch 400 and the loop antenna 501 are approximately When arranged orthogonally, a current flows through the data carrier side antenna coil 3422 by the induction electromagnetic field formed by the loop antenna 501.

As described above, according to the wristwatch 400 of the third embodiment, the longitudinal direction of the bar antenna 342 provided in the data carrier module 4 and generating a magnetic field by generating a magnetic flux from the longitudinal end is substantially the same as the loop antenna 501. Since it is arranged with respect to the gasoline meter 500 so as to be orthogonal to each other, the radio wave communication sensitivity becomes the best arrangement, and the bar antenna 342 in the communication with the reader / writer 502 of the data carrier module 4 is arranged. The arrangement can be optimized, and the communication sensitivity with the reader / writer 502 can be improved.
Further, since the data carrier module 4 is disposed in the storage portion 405 so that the longitudinal direction of the bar antenna 342 is along the extending direction of the band member 403, the reader / writer 502 is communicated with the reader / writer 502. The proximity of the data carrier module 4 to 502 can be performed more easily.

  When a predetermined bar antenna is mounted on the gasoline measuring instrument 500 instead of the loop antenna 501, that is, when communication of information between the gasoline measuring instrument 500 and the wristwatch 400 is performed between the bar antennas, these bars are used. By setting the cores constituting the antenna so as to face each other in such a direction that the longitudinal directions of the cores extend in substantially the same direction, the communication sensitivity of radio waves is maximized. Therefore, it is preferable that the bar antenna is arranged in the gasoline measuring instrument 500 so as to extend in the substantially same direction as the longitudinal direction of the bar antenna 342 provided in the wristwatch 400 that is adjacent thereto.
