In recent years, an IC card having a contact defined by ISO 7816-2 and ISO 7816-3 and a non-contact interface defined by ISO 14443 has been put into practical use.
On the other hand, a dual interface IC card with USB (Universal Serial Bus) contact has been developed (Patent Document 1). An IC card having a USB interface facilitates connection with a USB compatible device such as a PC, and has begun to attract attention as an ID card for network access such as an employee ID card.

  On the other hand, security ID modules called small SIMs, UIMs, and USIM cards have been incorporated in mobile phones. Even in Japan, it is incorporated into the latest mobile phones and put into practical use. A UIM (User Identity Module) is a small IC card in which contractor information issued by a mobile phone company is recorded, and is incorporated into a mobile phone and used to identify a user.

  This is an extension of functionality from a SIM (Subscriber Identity Module) that has the same function. In addition to contractor information, private information such as a phone book and personal identification information for credit payments are encrypted and registered. Is possible. Since it is based on SIM, it is sometimes called USIM (Universal SIM). The SIM is intended to use the GSM mobile phone service, but the UIM can be used, for example, by inserting it into an American cdma2000 mobile phone and receiving an international roaming service.

  Patent Document 1 proposes a dual interface IC card of contact and USB contact specified by ISO7816-2 and ISO7816-3. In addition, the applicant of the present application has previously proposed a SIM holder including a contact defined in ISO 7816-2 and ISO 7816-3 and a non-contact interface of ISO 14443 in Patent Document 2, Patent Document 3, and Patent Document 4. .

For example, a conventional SIM holder (of Patent Document 2) has the circuit configuration and appearance of FIG. FIG. 4A is a perspective view from the front side, but the SIM holder 1 is configured so that the insertion direction of the USB connector 7 and the insertion direction of the SIM 2 are configured in a straight line, and is inserted from the insertion port 15 at the right end. The SIM 2 enters and is fixed on the lower surface side of the contact terminal plate 12.
The SIM holder 1 has an antenna coil 11, and both ends thereof are connected to the SIM 2 via C4 and C8 terminals of the contact terminal plate 12. Thereby, even when the SIM 2 does not have an antenna coil, the antenna coil 11 of the SIM holder 1 enables non-contact communication.
Further, the data of the SIM 2 is transmitted to the USB / ISO 7816 I / F conversion IC 10 and the USB connector 7 via the contact pins and the terminal board.

  FIG. 5 shows a circuit configuration of another conventional (Patent Document 4) SIM reader / writer, which has a liquid crystal display 30 and an infrared receiving / transmitting unit. Various types of applications such as electronic money and electronic tickets are mounted on the SIM 2 to be mounted and can be used for various purposes. The USB port 7p means a portion where a USB connector is connected to a USB device. The SIM reader / writer and the SIM holder are functionally equivalent, and are different only in designation. In the case of the SIM reader / writer of FIG. 5, it is possible to make a transaction in contact with an external device via the USB port 7 p, and a non-contact transaction is also possible via the antenna coil 11. Further, the transaction content can be displayed on the liquid crystal display 30.

In recent years, radio timepieces have been put into practical use. Radio clocks are received by the Japan Standard Time Group (JJY), an independent administrative institution, and receive standard radio waves with time information transmitted by the ultra-high-performance antenna built into the watch case or band. It is a watch that has a function of automatically correcting.
The standard radio wave has been transmitted from June 1999 on the long-wave standard radio wave (40 kHz) from “Otakado and Yama standard radio wave transmission station” in Tomura-mura, Tamura-gun, Fukushima Prefecture in eastern Japan. On the other hand, in western Japan, it has been transmitted since October 2001 on the long-wave standard radio wave (60 kHz) from “Haganeyama standard radio wave transmission station” in Saga Prefecture. As a result, it is possible to receive standard radio waves throughout Japan including Okinawa and Hokkaido.
The standard radio wave is transmitted continuously for 24 hours, but temporary transmission may be interrupted due to equipment and antenna maintenance, lightning strike countermeasures, and the like. The long wave standard radio wave includes time codes such as hour, minute, day of the month since January 1, year (last two digits of the year), day of the week, and leap second information.

Conventionally, in a personal computer (PC) or the like, the file update time and the like are performed based on the internal clock provided in each PC, but the internal clock provided in the PC or workstation is not a high-precision one and is periodically Time adjustment was necessary.
For example, Patent Document 5 proposes to receive time information by FM multiplex broadcasting to maintain the clock function of the PC and maintain accuracy.

  As for the radio-controlled timepiece device itself, there are a number of prior documents such as Patent Document 6, Patent Document 7, Patent Document 8, and the like. A radio communication clock built-in mobile communication terminal is also described in Patent Document 7. However, there have not been many proposals for using standard radio waves in devices other than the watch itself or a PC. In particular, no device has been proposed that uses a radio-controlled clock to record the time, content of operations, and instructions of operations such as commerce and authentication, and to notify the other party of the information. .

  1 is a schematic circuit configuration block diagram of a SIM holder according to the present invention, FIG. 2 is a diagram showing a circuit configuration of a radio timepiece of the SIM holder, and FIG. 3 is a diagram showing a time code transmitted with a standard radio wave. .

Similar to the conventional structure shown in FIG. 4 or 5, the SIM holder 1 has a structure in which the SIM 2 is detachably mounted.
As shown in FIG. 1, the SIM holder 1 has memories such as an SRAM 5 and a flash ROM 6 connected via a BUS 4 to a CPU 3 that controls the entire SIM holder 1. The SIM holder 1 includes a USB connector 7 and can be connected to a USB device such as a PC (personal computer) via the USB connector 7.
The SIM 2 and the CPU 3 are connected via an ISO 7816 interface (I / F), and the USB connector 7 and the CPU 3 are connected via a USB interface (I / F). The SIM holder 1 can have an antenna coil 11 for non-contact communication, and is connected to the SIM 2 by an ISO 14443 interface (I / F). In this case, electronic commerce, authentication, etc. by non-contact communication with an external device are also possible.

  A feature of the SIM holder 1 of the present invention is that it has a radio timepiece 20 portion, which is a standard radio wave receiving antenna 21 and a receiver 22, a time data code circuit 23, a timepiece circuit 24, and a battery 25. It consists of and. As is well known, the radio timepiece 20 is a timepiece having a function for correcting time and the like in the timepiece circuit 24 based on data obtained by receiving the long-wave standard radio wave of 40 kHz or 60 kHz.

  The standard radio wave receiving antenna 21 is made of a ferrite core material formed and fired in a bar shape, U shape or C shape, and a wire ring wound in a helical or solenoid shape. Has appeared. In the present invention, any size that can be accommodated in the box of the SIM holder 1 may be used, and those employed in ordinary watches or the like can be used.

FIG. 2 is a diagram illustrating a circuit configuration of the radio timepiece 20 of the SIM holder 1.
The radio-controlled timepiece 20 includes a standard radio wave receiving antenna 21 and a 40 kHz receiver 22 (as described above, there is a standard radio wave of 60 kHz, but will be described by taking 40 kHz as an example), and a time when the 40 kHz receiver 22 is connected. A data decoding circuit 23 and a clock circuit 24 connected to the time data decoding circuit 23 are provided.
The battery 25 supplies power to the MPU 232 and the like of the time data decoding circuit 23, and a primary battery, a secondary battery, a combination of a solar panel and a secondary battery, or the like can be used.

The 40 kHz receiver 22 includes an amplifier 221 that amplifies the radio wave received by the antenna 21, a detector 222 that detects the signal amplified by the amplifier 221, and a demodulation that demodulates the time code (TC) from the signal detected by the detector 222. It is comprised by the device 223.
The time data decoding circuit 23 includes a signal detection circuit 231 that outputs a reference 1 second signal and a data signal from the time code (TC) from the 40 kHz receiver 22, an MPU 232 that processes a signal from the signal detection circuit 231, and a buffer memory 233. It is prepared for.
Further, the clock circuit 24 oscillates a signal with a frequency of 32768 Hz, a frequency divider 242 that divides the oscillation frequency of the oscillator 241 to obtain a timing of 1 second, counts the frequency-divided output, An hour / minute / second counter 243 for obtaining the second and a time display 244 for displaying the count result are included.

Here, the contents of the standard radio wave will be described with reference to FIG.
The standard radio wave transmits data such as the cumulative number of days from January 1st, hours, minutes, etc. in binary code, with 60 seconds as one cycle. One bit is formed by a rectangular pulse of 1 hertz, and data contents are set by different pulse widths. The radio timepiece is configured to receive the standard radio wave, correct the time so that the correct time is displayed (or instructed) based on the reception result, and display the correct time.

FIG. 3 shows a time code transmitted with a standard radio wave. FIG. 3A shows a time code at a normal time (other than 15 minutes and 45 minutes per hour), and FIG. 3B shows a time code at a call code transmission time (15 minutes and 45 minutes per hour). The time between 0 seconds and 40 seconds in FIG. 3B is the same as that in FIG.
Minute data, time data, day-of-day data, parity data, spare bits, year data, day of the week data, etc. are sent continuously during a period of 0 to 60 seconds of the standard radio wave.
The width of P1, P2,... Called markers embedded in a pulse signal constituting one cycle in 60 seconds every 10 seconds is detected. The marker P1 is transmitted with a width of 200 msec, but the width increases or decreases depending on the reception status. The allowable range can be set in the MPU 232. For example, if it is within 200 msec ± 10%, it is handled as no error.

In FIG. 3A, a wide rectangular wave with a width of 800 msec means that the signal value is 0, and a rectangular wave of 500 msec (a rectangular wave with hatched hatching in FIG. 3) has a signal value of 1 means. Parity of “time” is recorded in PA1, and parity of “minute” is recorded in PA2, and it can be determined whether or not there is no error in the read time code (time code).
In the case of FIG. 3 (A), the total date from January 1 is a rectangular wave with 100, 40, and 1 being 500 msec, the total is 141 days, and the Western calendar displays the last two digits. It is read from 2004. The time is 12:26.
Therefore, it is known by the time code that it is 12:26 on May 20, 2004.

Next, time code reading from standard radio waves will be described.
The 40 kHz receiver 22 starts to operate when the power switch of the radio timepiece is turned on, when a battery is inserted, or when a reset is performed. In addition, a wristwatch or the like has a built-in system of scheduled reception that automatically receives radio waves twice between 2:00 am and 4:00 am every day and forced reception that can be received at an arbitrary time. It may be received every hour. The SIM holder of the present invention can be a similar system.

The received signal amplified by the amplifier 221 is detected by the detector 222, and the time code (TC) is demodulated by the demodulator 223. The time code (TC) is normally demodulated when the reception intensity of radio waves is sufficiently high and is not affected by noise, and noise is mixed when radio waves are weak or when external noise or the like is generated.
The time code (TC) output from the demodulator 223 is input to the signal detection circuit 231 of the time data code circuit 23. The signal detection circuit 231 samples the time code (TC), detects a rising edge, generates a second signal, and simultaneously decodes the data signal from the time code (TC). The signal detection circuit 231 performs the following determination and outputs it to the MPU 232.

(1) If the low level continues for 200 msec ± 5 msec after the high level for 800 msec ± 5 msec, the judgment is “0”.
(2) When the low level continues for 500 msec ± 5 msec after the high level for 500 msec ± 5 msec, the judgment is “1”.
(3) When the low level continues for 800 msec ± 5 msec after the high level for 200 msec ± 5 msec, the determination of “position (P)”.
(4) If the previous data is “Position (P)” and the current data is also at a high level for 200 msec ± 5 msec, and then the low level continues for 800 msec ± 5 msec, then “Marker (M)” Judgment.
(5) When other than the above (1) to (4) and when the next rising edge cannot be detected within 1 second ± 10 msec, “error” is determined.

  In the MPU 232, the data from the signal detection circuit 231 is stored in the buffer memory 233, and the memory address pointer is incremented by one. When an error occurs, the memory address pointer is set to 0, and the state returns to the state where the first rising edge is detected. When data is stored in the buffer memory 233, “marker (M)” data is detected. When this state is first detected, the memory address is stored in the marker address pointer. Further, when data is stored in the buffer memory 233 and the number of data including the “marker (M)” data reaches 120, a time code (TC) continuous for 2 minutes is obtained. If an error occurs in the middle, the marker address pointer is cleared, the memory address pointer is set to 0, and the process returns to the state where the first rising edge is detected.

  When the continuous two-minute time code (TC) is stored in the buffer memory 233, the data of the first and second minute time codes (TC) are extracted from the buffer memory 233. At this time, since the address of the marker address pointer is not constant, the address stored in the marker address pointer is used as a base, and the second position of the time code (TC) is used as an offset. By adding the base and the offset, the data of the parities PA1 and PA2 can be extracted from the buffer memory 233 for the first minute. The second minute data can be similarly extracted by using the address stored in the marker address pointer plus 60 as a base.

  Compare the time code (TC) data of the 1st minute and the 2nd minute, and confirm that the data other than the minute, hour, PA1, PA2 data are the same, and the minute and hour data are the second minute Confirm that +1 minute is set in the first minute. If the parity value is confirmed and everything is normal, the received time code (TC) is regarded as valid. When the time code (TC) is valid, “minute” and “hour” data obtained by adding 1 minute to the time code (TC) of the second minute are prepared, and the time of the clock circuit 24 is corrected simultaneously with the next second transmission. Correct the displayed contents.

  The MPU 232 of the time data decoding circuit 23 receives radio waves once every hour and corrects and displays the built-in clock so that there is no display time error. In principle, one reception is performed for two (two consecutive minutes) until the correct time code (TC) is continuously received. However, in recent years, the time can be adjusted in a shorter time. A method has been developed. Therefore, the radio timepiece used in the present invention is not limited to the above-described one, and modifications and improved embodiments can be adopted.

  As a radio wave clock receiving IC, there is “CF9501A (bare chip product)” manufactured by Japan Precision Circuits Co., Ltd. or “SM9501AV” which is a package product thereof, and these can be used. This has a built-in two-station tuning switching circuit, and can amplify and detect a long wave standard wave received by an antenna and output a binarized time code. The bare chip product has a size of about 1.43 × 2.36 mm × 300 ± 30 μm (thickness), and the package product has a size of about 5.1 × 6.4 mm × 1.5 mm (thickness).

The radio clock receiver IC has the following characteristics.
(1) When there are two standard radio wave transmission stations with different carrier frequencies as in Japan, it is necessary to switch the tuning frequency depending on the reception area. As a result, the two-station tuning switching circuit is built in while solving the number of parts and the cost problem. Therefore, a single IC can handle 40 kHz and 60 kHz standard radio waves.
(2) “CF9501A” uses a Bi (bi) CMOS process, and has a high input sensitivity (0.5 μVrms) / wide input dynamic range (0. 5 μVrms to 80 mVrms)).

The main body portion of the SIM holder 1 is not limited to the configuration illustrated in FIG. 1, and may include a liquid crystal display 30 as illustrated in the SIM reader / writer having the conventional configuration in FIG. 5. In that case, the current time can be displayed on the liquid crystal display.
In addition, the SIM 2 to be installed can store an electronic certificate used for authentication, in addition to applications such as electronic money and electronic tickets. The electronic certificate is a mechanism for guaranteeing that the electronic certificate has been transmitted from the person himself, and is encrypted and transmitted to the other party.

When the antenna coil 11 is provided in the SIM holder 1, the end thereof is connected to the C4 and C8 terminals of the reader / writer terminal plate 12 so as to be electrically connected to the non-contact communication function unit of the SIM2. The SIM2 data is connected to a USB port such as a PC via the USB / 7816 conversion IC chip 10 (see FIG. 5).
The SIM holder 1 has an upper lid portion 18 and a lower case portion 19 formed by injection molding of polycarbonate, polypropylene, acrylic resin, etc., and a contact terminal plate 12, a circuit board, an antenna inside the space formed by the lower case portion and the like. The coil 11 can be incorporated.
It is preferable that the SIM lid is formed thinly up to the SIM insertion port 15 side of the upper lid portion 18 and the stop end portion of the SIM 2 so that the SIM can be inserted and fixed (see FIGS. 4 and 5).

Next, the usage method of the SIM holder incorporating the radio timepiece of the present invention will be described.
Since the SIM holder 1 of the present invention maintains the time corrected to the standard time in a timely manner as described above, it is possible to record an accurate time when a transaction is made by connecting to another device.
Therefore, it can be used as follows.
(1) When there is an operation instruction to the SIM, time information based on the radio timepiece is transmitted to the SIM via the CPU of the SIM holder, and the time information and the contents of the operation instruction are recorded in the flash ROM of the SIM holder. This is because the history can be traced later and can be deleted. At this time, the SIM or SIM user identification ID may be recorded simultaneously. This is because the SIM holder can be used even if the SIM itself is attached or detached, so that the user can be specified.
(2) When there is an operation instruction to the SIM, the time information based on the radio timepiece is transmitted to the SIM via the CPU of the SIM holder, and the time information and the electronic certificate read from the SIM are transmitted to the business partner. The time information and the electronic certificate information are recorded in the flash ROM of the SIM holder. This is so that the history can be traced later, and the SIM or SIM user identification ID may be recorded at the same time.

In the case of (2) above, when the supplier's device has a built-in clock circuit, the consistency can be confirmed by comparing both pieces of time information. When the clock circuit of the supplier's device is not a radio timepiece, time information mismatch may occur, but at least the reliability of the time information on the SIM holder side can be ensured.
Also, the electronic certificate and time information may be encrypted in the SIM and decrypted on the receiving side.
The time information, instruction content, operation instructor ID, and the like can be output and displayed on the liquid crystal display. Alternatively, these contents may be output by an external printer.

  In the above, operation instructions specifically include product purchases and service reservations, electronic commerce such as purchase of admission tickets and boarding tickets, reserved seat tickets, electronic grant of authentication, entrance and facility entrance operations, digital equipment There are no particular restrictions on the operation instructions. Further, the transaction and settlement may be performed via the USB connector 7 or performed by non-contact communication via the antenna coil 11.

Standard radio waves are not received due to equipment and device maintenance and natural disasters. The operational efficiency of standard radio waves is said to be 98.4% (FY2000) (incorporated administrative institute, Communications Research Laboratory homepage). In such a case, the CPU of the SIM holder may determine the state, cut off the electrical connection between the SIM and the CPU, and disable the SIM holder authentication function. The same can be done when the SIM holder is used in a building or in a place where the radio field intensity is low, such as an underground facility.
However, if the time accuracy of the clock circuit 24 is kept high (average monthly difference of about ± 15 seconds), the accuracy within one day can be secured to about ± 0.5 seconds, and no substantial problem will occur. Conceivable.

  In the present specification, the SIM holder with a built-in radio timepiece has been described. However, the present technology can also be applied to various media having a personal authentication function and connected to a USB device via a USB connector. For example, even if the present invention is applied to a medium such as “eToken” (trademark) and “iKey” (trademark) having a security function and used for e-commerce and e-business, and various memory media having a USB connector, the effect of the present invention can be obtained. It is obvious that it is obtained.
