The R / W module 41 demodulates the signal from the signal processing circuit 91 controlled by the CPU 51, the oscillating circuit 92 controlled by the signal processing circuit 91 and performing an oscillating operation, and the signal from the data carrier 11 to the signal processing circuit 91. Output demodulation circuit 93
And an LED 90 that is lit to perform communication display during communication operation.

The demodulation circuit 93 receives a signal detected by the coil L3 forming the coil 82.
And a gate circuit 95 that gates the output of the receiving circuit 94 in synchronization with the gate signal supplied from the signal processing circuit 91.
And have. The amplifier circuit 96 amplifies the signal supplied via the gate circuit 95 and outputs it to the detection circuit 97. The detection circuit 97 detects the signal input from the amplification circuit 96. The sample hold circuit 98 samples and holds the output of the detection circuit 97 and outputs it to the comparator 99. The comparator 99 compares the output of the sample hold circuit 98 with a predetermined reference value set in advance, and outputs the comparison result to the signal processing circuit 91.

The coil L1 forming the coil 82 is also connected to the oscillation circuit 92.

A capacitor 111 is connected to the data carrier 11 in parallel with the coil L2 forming the coil 13 to form a tank circuit. Rectifying and smoothing circuit 112
Is configured to rectify and smooth the output of the tank circuit and supply it as electric power to each circuit. R / W module 41
From the data carrier 11, energy and information are supplied by electromagnetic induction via the coil 13 (L2).
Since the signal used as energy and the signal used as information are set so that their frequency bands are different, they can be easily separated.

The information component detected by the tank circuit is
The signal is supplied to the demodulation rectification circuit 113 and demodulated and rectified (detected). Therefore, this demodulation rectification circuit 1
A capacitor 114 is connected to 13 in parallel.
The detection output of the demodulation rectification circuit 113 is supplied to the communication logic circuit 203 of the IC 201. I
In addition to the communication logic circuit 203, the C201 has a nonvolatile memory (EEPROM) 202 and a modulation circuit 204 including a shunt circuit. Modulation circuit 2
04 is composed of FETs 213 and 214 connected to the shunt resistors 211 and 212, respectively. The shunt pulse t _s is supplied from the communication logic circuit 203 to the gates of the FETs 213 and 214.

The coil 82 of the R / W module 41 when the data carrier 11 is mounted on the portable device 1 as shown in FIGS. 4 and 5, or when the data carrier 11 is closely arranged as shown in FIGS. 6 and 7. (L1, L3) and data carrier 1
The first coil 13 (L2) is arranged sufficiently close to each other so that a signal can be transmitted and received between the two by electromagnetic induction.

When a signal is sent from the R / W module 41 to the data carrier 11, the CPU 51 inputs the transmission data (NRZ signal) shown in FIG. 11A to the signal processing circuit 91 of the R / W module 41. It The signal processing circuit 91 generates the biphase signal shown in FIG. 11B in response to this transmission data. Then, from this bi-phase signal, as shown in FIG.
Generate a WM signal. When the bi-phase signal is logic H, 70% of the PWM signal is at a high level (a signal having a duty of 70%), and when the bi-phase signal is logic L, the PWM signal is 30% of the period. It is set to a high level (a signal having a duty of 30%).

Further, the signal processing circuit 91 uses the PWM
In the section where the signal is logic H, as shown in FIG.
A PNM signal, which is a pulse train signal having a predetermined frequency, is generated. The PWM signal shown in FIG.
The PNM signal shown in (D) is supplied to the oscillation circuit 92. The oscillation circuit 92 operates only during the period when the PWM signal is logic H, and supplies the coil 11 with a signal corresponding to the PNM signal. As a result, the coil L1 is shown in FIG.
The current shown in flows.

Not only the PNM signal but also the P
The WM signal is also supplied in order to prevent the residual waveform whose supply of the PNM signal is stopped from remaining in the coil L1. That is, the operation of the oscillator circuit 92 is designed to be stopped immediately when the PWM signal is at a low level.

A current as shown in FIG. 11 (E) is applied to the coil L.
When passed to 1, the coil 13 (L2) of the data carrier 11
An electric current as shown in FIG. That is, the corresponding induced current flows through the coil 13 while the current is being supplied to the coil L1 and is not supplied (the supply of the current to the coil L1 is stopped).
Even during the period, the residual vibration component flows due to the action of the tank circuit formed by the coil 13 and the capacitor 111. The demodulation rectifier circuit 113 detects the length of a constant level period from this current flowing through the coil 13 excluding the residual vibration component whose level gradually decreases, and outputs the detection result to the communication logic circuit 203. The communication logic circuit 203 determines the logic based on the detection result, and executes the process corresponding to the determination result (for example, reading data from the EEPROM 202).

On the other hand, when a signal is output from the data carrier 11 to the R / W module 41, the signal processing circuit 91
Is the PWM shown in FIG.
The signal and the PNM signal shown in FIG. 12B are output. The PWM signal and the PNM signal have a duty of 50%. As a result, the coil L1 is shown in FIG.
The current shown in (C) flows. Corresponding to the change in current shown in FIG. 12C, the coil 13 of the data carrier 11
The resonance current shown in FIG. 12G flows through (L2).
Since the coil L2 forms a tank circuit with the capacitor 111, even if the change in the current flowing through the coil L1 is stopped, a residual vibration component that gradually decreases remains. Demodulation rectifier circuit 1
13 demodulates this and supplies the detection output shown in FIG. 12 (D) to the communication logic circuit 203.

The communication logic circuit 203 is an EEPROM.
Data obtained by adding a parity bit to data (for example, a password) read from 202 is converted into a serial signal, which is shown in FIG. 12E in synchronization with each pulse of the detection output shown in FIG. A transmission signal (bi-phase signal) is generated. That is, this transmission signal is the EEPROM 2
This corresponds to the logic of the data read from 02.

The communication logic circuit 203 is further shown in FIG.
The transmission shunt pulse shown in FIG. 12 (F) is generated in synchronization with the falling edge of the detection output shown in 2 (D). This transmission shunt pulse is output only when the transmission signal shown in FIG. 12E is at a low level, and is not output when it is at a high level.

The shunt pulse is applied to the gates of the FETs 213 and 214 of the modulation circuit 204.
The FETs 213 and 214 are turned on when this transmission shunt pulse is applied, and absorb the residual vibration component generated in the tank circuit configured by the coil L2 and the capacitor 111. As a result, as shown in FIG. 12 (G), the level of the residual vibration component of the tank circuit at the timing when the transmission shunt pulse occurs is smaller than the level of the residual vibration component of the tank circuit at the timing when the transmission shunt pulse does not occur. .

The coil 13 of the data carrier 11 is shown in FIG.
2 (G) flows, the R / W module 41
A current shown in FIG. 12 (H) flows through the coil L3 by electromagnetic induction. As shown in FIG.
Corresponding to the waveform shown in FIG. 2 (G), large and small differences occur in the level of the residual vibration component period.

The receiving circuit 94 receives the signal flowing through the coil L3 and outputs it to the amplifying circuit 96. The signal processing circuit 91 supplies the gate circuit 95 with a reception gate signal having a width of a predetermined period t _{g at} the timing when the residual vibration component is generated, in synchronization with the PWM signal output to the oscillation circuit 92. That is, the reception gate signal shown in FIG. 12 (I) is generated only during the low level period of the PWM signal shown in FIG. 12 (A). The gate circuit 95 is turned on while the reception gate signal is at the high level, and outputs the output of the reception circuit 94 to the amplification circuit 96. As a result, the amplification circuit 96
As shown in FIG. 12 (J), only the signal in the period of the residual vibration component is amplified and output to the detection circuit 97.

The detection circuit 97 detects the output of the amplification circuit 96 and supplies the detection output shown in FIG. 12 (K) to the sample hold circuit 98. The sampling pulse shown in FIG. 12L is supplied from the signal processing circuit 91 to the sample hold circuit 98, and the output of the detection circuit 97 is sampled and held at the timing when this sampling pulse is supplied. As described above, FIG.
The received waveform shown in (J) has a large residual vibration component and a small residual vibration component. Therefore, the value sampled and held by the sample and hold circuit 98 becomes a larger value when the residual vibration component is large, and becomes a smaller value when the residual vibration component is small.

The reference value of the comparator 99 is set to an intermediate value between the large value and the small value. For this reason,
When the residual vibration component is large (the sample hold circuit 98
When the hold value is larger than the reference value), a high level signal is output, and when it is smaller (the hold value of the sample hold circuit 98 is smaller than the reference value), a low level signal is output. As a result, the output of the comparator 99 becomes as shown in FIG. The signal processing circuit 91 determines its logic from the received signal (bi-phase signal) of the comparator 99. Then, the determination result is CP
Output to U51.

Next, the operation of the portable device 1 will be described with reference to FIG.
This will be described with reference to the flowchart in FIG. As described above, when using the mobile device 1, the user mounts the data carrier 11 on the mobile device 1 as shown in FIGS. 4 and 5 (as shown in FIGS. 6 and 7). Including when to place). Then, in step S1, the portable device 1
When a predetermined key of the keyboard unit 2 is operated to turn on the power, the process proceeds to step S2, and the CPU 51
Starts the operation of the R / W module 41.

That is, the CPU 51 controls the signal processing circuit 91 to instruct the reading of the password stored in the data carrier 11. The signal processing circuit 91 controls the oscillation circuit 92 to generate a password reading signal. This signal is transmitted from the coil L1 to the coil 13 by electromagnetic induction, and is supplied from the coil 13 to the demodulation rectification circuit 113. The demodulation rectification circuit 113 demodulates this signal and outputs it to the communication logic circuit 203. The communication logic circuit 203 receives the EEPR signal corresponding to the input signal.
The password stored in the OM 202 is read out.

Then, this password is supplied from the communication logic circuit 203 to the modulation circuit 204, and the coil 13
It is transmitted to the demodulation circuit 93 via (L2) and 82 (L3). Then, it is demodulated by the demodulation circuit 93 and supplied to the signal processing circuit 91. The signal processing circuit 91 reads this password and outputs it to the CPU 51. CPU51
Transfers this password to the RAM 53 and stores it.

Next, in step S3, it is determined whether the password has been read correctly by checking the number of bits of the read data and the parity check of the bit pattern, and the password has been read correctly. If not, the process returns to step S2, the R / W module 41 is controlled again, and the password reading operation is executed.

When the password can be correctly read, the process proceeds from step S3 to step S4, and the user is prompted to input the password. That is, the CPU 51 displays a message to the user to input the password in the liquid crystal display unit 3. The user operates the keyboard unit 2 in response to this message and inputs the password that he / she has stored.

Next, the CPU 51 proceeds to step S5.
The password entered in step S4 and the EEPROM
The password read from 202 and compared with the password stored in the RAM 53 is compared to determine whether the two match. If they do not match, the process returns to step S4, and the user is prompted to enter the password again.

Then, when the password read from the EEPROM 202 and the password input by the user match, the CPU 51 causes the keyboard unit 2 to proceed.
Various processes are executed in response to a command input by the user.

On the other hand, when the passwords do not match, the CPU 51 prohibits execution of various processes. As a result, the EEPROM of the data carrier 11
The data stored in the 202, the RAM 53 of the portable device 1, and the mini disk unit 66 are also prohibited from being read or written.

Therefore, even if the portable device 1 is left behind somewhere or the portable device 1 itself is stolen, abuse of the portable device 1 is prevented.

Further, even if both the data carrier 11 and the portable device 1 are stolen, various processes are performed unless the user inputs the password stored in the data carrier 11 from the keyboard unit 2. Since it cannot be executed, it can be prevented from being abused.

As described above, the E of the data carrier 11 is
When the password is stored in the EPROM 202, the data carrier 11 itself is individually owned by each individual, so that the mobile device 1 can be commonly used by a plurality of users while ensuring mutual confidentiality. Will be possible.

As described above, when the passwords match, the portable device 1 is ready for use. For example, CP
When U51 is instructed to switch to the transmission mode, the CPU
51 controls the transmission / reception switching unit 59 via the transmission / reception control flag circuit 65 to switch the transmission / reception antenna 58 to the transmission unit 64 side. Thereby, for example, the audio signal input from the microphone 55 is converted into the A / D converter 56.
Can be A / D-converted and can be wirelessly transmitted to the center via the transmitting unit 64, the transmission / reception switching unit 59, and the transmitting / receiving antenna 58.

Further, the voice data taken in from the microphone 55 can be stored in the voice data memory 57 as needed. The data stored in the voice data memory 57 is sent to the transmission unit 6 via the transmission data memory 63.
It is also possible to supply the data to the center 4 and transmit it to the center via the transmission / reception switching unit 59 and the transmission / reception antenna 58.

On the other hand, when the switching to the reception mode is instructed, the CPU 51 causes the transmission / reception control flag circuit 65 to transmit.
The transmission / reception switching unit 59 is controlled to transmit / receive the antenna 5
8 is connected to the receiving unit 60 side. Therefore, the signal wirelessly received from the center by the transmitting / receiving antenna 58 is supplied to the receiving unit 60.

When the received data is image data or character data, it is supplied from the receiving unit 60 to the received data memory 62 and stored therein. And
This data is output and displayed on the liquid crystal display unit 3. Also, this data is stored in the mini disk unit 66.
Is appropriately supplied to the EEPR of the data carrier 11 via the R / W module 41 for recording on a mini disk.
It can be stored in the OM 202. Or IC
It is possible to write to the IC card via the card interface 67.
