DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of a non-contact type information recording medium (hereinafter referred to as a wireless card) 101 according to the present invention.
It is made thin so as to be portable, and has a built-in wireless communication antenna, information storage element, and other circuit elements.

FIG. 2 shows a portable terminal device (handy device) as an information processing system using the wireless card according to the present invention.
The terminal) 200 is an external view and has a failure mode determination function for specifying a failure location of the wireless card shown in FIG. 1 and a function for reading data from the wireless card as an emergency means.

In FIG. 2, the mobile terminal device 200 is roughly divided into a main body 201 and a lid 205 of the main body 201. The lid 205 is openably and closably supported by the main body 201, and a transmission / reception antenna 202 for performing wireless communication with the wireless card 101 is embedded in the back surface of the lid 205 (a surface facing the main body 201). ing. Further, when the wireless card 101 is fitted into or inserted into the back surface of the lid body 205, the transmitting / receiving antenna 20
A wireless card fixing unit 206 for fixing the wireless card 101 is provided so that the wireless card 101 and the wireless communication device 2 are in a positional relationship so as to obtain an optimum communication state.

Data is transmitted / received to / from the wireless card 101 through the antenna 202 except when emergency data is read. A keyboard 204 for inputting various information and a display unit 203 for displaying various information are provided on the surface of the main body 201.

FIG. 3 shows a portable terminal device 200 according to the present invention.
3 shows a pseudo internal structure of a wireless card 101 that communicates with the wireless card 101. A loop antenna 102 formed by winding a copper wire once or a plurality of times is embedded along the edge of the wireless card 101.

Inside the loop antenna 102, a CPU,
A memory, an IC chip 103 in which those peripheral circuit elements are integrated into an LSI, and chip capacitors 104 and 105 are embedded, and one terminal of the loop antenna 102 is connected to one terminal of each of the IC chip 103 and the capacitors 104 and 105. The other terminal of the loop antenna 102 is connected to the other terminals of the IC chip 103 and the capacitors 104 and 105, respectively.

Capacitors 104 and 105 are capacitors for forming a resonance circuit together with the circuits in the antenna 102 and the IC chip 103 and for giving other time constants in order to transmit and receive a carrier wave of a predetermined frequency.

FIG. 4 shows a circuit configuration example equivalent to the internal circuit of the wireless card 101. In FIG. 4, I
It is assumed that the C chip 103 is equivalent to the load resistor 401 having the resistance value R12.

The loop antenna 102 has an inductance L
It is assumed to be equivalent to 12 coils 102. As described above, the internal circuit of the wireless card 101 is configured by connecting the capacitor 104 having the capacitance C12, the capacitor 105 having the capacitance C22, the loop antenna (coil) 102 having the inductance L12, and the load resistor 401 equivalent to the IC chip 103 in parallel. It is equivalent to the resonant circuit.

Now, in the case where each part of the internal circuit of the wireless card as shown in FIG. 4 is not damaged and is operating normally,
The wireless card 101 resonates at a frequency f1 f1 = 1 / (2π (L12 × (C12 + C22))).

However, the capacitor 104 (capacity C12)
When the capacitor 105 is damaged, it resonates at a frequency f2 f2 = 1 / (2π (L12 × C22)), and when the capacitor 105 (capacitance C22) is damaged, the frequency f3 f3 = 1 / (2π (L12 XC12)).

Further, it will be clear from the circuit configuration of FIG. 4 that if the IC chip 103 or the loop antenna 102 is damaged, it will resonate at frequencies other than f1, f2, and f3.

Therefore, it is understood that the failure of the wireless card can be determined by detecting the resonance frequency which changes depending on the failure location of the internal circuit of the wireless card 101.

FIG. 5 shows an equivalent circuit of main parts of the wireless card 101 and the portable terminal device 200 when the wireless card 101 and the portable terminal device 200 perform wireless communication. The circuit configuration on the wireless card 101 side is the same as in FIG. An equivalent circuit on the side of the mobile terminal device 200 will be described.

The internal circuit of the main part of the mobile terminal device 200 is
A variable signal source (voltage value V11) 503, a selectivity adjusting resistor (resistance value R11) 504, a variable tuning capacitor (capacitance C11) 505, and a transmitting / receiving antenna (coil) 202 having an inductance L11 are connected in series. It is equivalent to a resonant circuit.

The mutual inductance between the coil having the inductance L11 and the coil having the inductance L12 is M12. For example, when M12 = 0, it is assumed that the wireless card 101 is outside the transmission area of the mobile terminal device 200. For example, M12 = 0.98 is assumed when the wireless card 101 is within the communication area of the mobile terminal device 200.

When the carrier wave of the frequency f1 is transmitted from the mobile terminal device 200, if all the elements in the wireless card 101 are not damaged, the resonance circuit on the wireless card 101 side resonates at the frequency f1.

At this time, when the wireless card 101 is outside the communication area (M12 = 0), the voltage change between the transmission / reception antenna 202 on the portable terminal device 200 side and the both ends depends on the resistance value R11 of the selectivity adjusting resistor 504. If the determined selectivity is Q11, as shown in FIG. 6, the amplitude Q11 × V11
Shows a waveform that changes at a predetermined frequency.

On the other hand, the wireless card 101 is the mobile terminal device 2
In the communication area of 00 (M = 0.98), the inductance L11 of the transmitting / receiving antenna 202 of the mobile terminal device 200 is affected by the mutual inductance M12, and the resonance frequency of the resonance circuit in the wireless card 101 changes. In addition, as shown in FIG. 7, the transmitting / receiving antenna 2 is compared to when the wireless card 101 is outside the communication area (M12 = 0).
The amplitude of the voltage change across 02 becomes small.

As is apparent from FIGS. 6 and 7, the wireless card 101 resonating at the frequency f1 is installed in the portable terminal device 200.
When it is brought close to the transmitting / receiving antenna 202 of
It can be seen that the voltage at both ends of 02 is lower than that when the wireless card 101 is not provided.

When a wireless card resonating at the frequency f2 is inserted in the transmission area on the side of the mobile terminal device 200 that is transmitting the carrier wave of the frequency f1, as shown in FIG. Is reduced, but Fig. 7
Radio card 1 resonating at frequency f1 as shown in
Compared with the case of 01, the decrease is small.

Similarly, the transmission / reception antenna 202 of the mobile terminal device 200 transmitting the carrier wave of the frequency f2 receives the wireless card 101 resonating at the frequency f2.
Wireless card 1 when brought close to the transmitting / receiving antenna 202 of
Compared with the case where 01 resonates at a frequency other than the frequency f2, the voltage drop across the transmission / reception antenna 202 becomes significant.

Furthermore, the transmitting / receiving antenna 202 of the mobile terminal device 200 transmitting the carrier wave of the frequency f3 is provided with the wireless card 101 resonating at the frequency f3.
Similarly, when the wireless card 101 is brought closer to the transmitting / receiving antenna 202, the voltage drop across the transmitting / receiving antenna 202 becomes more significant than when the wireless card 101 resonates at a frequency other than the frequency f3.

As described above, the resonance frequency of the internal circuit of the wireless card 101 can be detected by observing the decrease in the voltage value at both ends of the transmitting / receiving antenna 202 on the side of the portable terminal device 200. It can be said that it is effective in determining.

FIG. 9 schematically shows the internal structure of the mobile terminal device 200. In FIG. 9, the data communication circuit 806 outputs modulated data in which the data to be transmitted to the wireless card 101 is modulated at a predetermined frequency and is output to the changeover switch 805.

The changeover switch 805 switches between a normal data communication mode and a failure determination mode. The modulated data output from the data communication circuit 806 and a carrier wave of a predetermined frequency output from the carrier wave transmission circuit 807. Select one of them to output to the driver 804,
At the same time, the tuning of the tuning circuit 803 is adjusted at the same time. In the data communication mode, the changeover switch 805 selects the modulated data output from the data communication circuit 806 and outputs it to the driver 804.

The modulated data is amplified by the driver 804,
A tuning circuit 803 is driven by the modulated data, and a data carrier of a predetermined frequency is transmitted to the wireless card 101 via the transmitting / receiving antenna 202.

On the other hand, the carrier wave of the transmission data from the wireless card 101 to the portable terminal device 200 is the transmission / reception antenna 20.
2. Received via tuning circuit 803, driver 811
The data communication circuit 806 performs demodulation processing, predetermined information processing, and the like.

However, if there is no response from the wireless card 101 even after a lapse of a predetermined time after transmitting the data from the mobile terminal device 200, the data communication circuit 806 instructs the carrier transmission circuit 807 and the changeover switch 805 to determine the failure mode. Support to switch to.

When the mode is switched to the failure determination mode, the carrier wave transmission circuit 807 outputs carrier waves of a plurality of frequencies, for example,
The carrier waves of frequencies f1 to f3 are output. Since the failure determination mode is selected by the changeover switch 805, the tuning circuit 803 is tuned accordingly to the frequency f1.
Adjust at the same time according to ~ f3.

The carrier wave output from the carrier wave transmission circuit 807 is output to the driver 804 via the changeover switch 805, amplified here, and transmitted to the wireless card 101 via the tuning circuit 803 and the transmission / reception antenna 202.

The level discrimination circuit 808 is used for the transmission / reception antenna 2
02, which constantly monitors the voltage across the transmission / reception antenna 202. That is, the wireless card 101
Is put in the communication area of the transmitting / receiving antenna 202, the voltage drop across the antenna 202 becomes significant only at a certain frequency, that is, at the resonance frequency of the wireless card 101. The level determination circuit 808 detects this voltage drop.

The failure mode determination circuit 809 determines the failure mode by determining at which frequency the level has dropped, considering the transmission timing of the carrier wave transmission circuit 807.
That is, for example, when the level determination circuit 808 determines that the voltage across the antenna 202 has dropped, if the frequency of the carrier wave transmitted from the carrier wave transmission circuit 807 is f2, it is determined that the capacitor 104 has failed. You can
When the level determination circuit 808 determines that the voltage across the antenna 202 has dropped, if the frequency of the carrier wave transmitted from the carrier wave transmission circuit 807 is f3, it can be determined that the capacitor 105 is defective.

Then, such a discrimination result is displayed on the display circuit 8.
10 is driven and displayed on the display unit 203. By detecting the resonance frequency of the wireless card 101 by the mobile terminal device 200 having the above-described configuration and operation, the failure location of the wireless card 101 is specified, that is, the damage of the capacitor 104 or the capacitor 105 is detected. However, the identification of the failure point is not limited to the capacitor 104 or the capacitor 105, but if a carrier wave having a frequency corresponding to each failure point is used,
It goes without saying that the failure location can be specified more precisely. The method of obtaining the frequency corresponding to each failure location can be easily obtained by performing a simulation based on the equivalent circuit of the internal circuit of the wireless card 101.

When it is determined from the determination result of the failure mode determination circuit 809 that damage other than the IC chip 103, that is, it is determined that data can be read from the memory element incorporated in the IC chip 103. The emergency data read function of will be described.
