The IC card 10 'can record and read information related to a transaction or other data related to identification / verification information, and at the same time update the information. An integrated circuit or IC (12 ') capable of wirelessly writing, reading, and updating data to the IC (12') from the outside in a non-contact manner. It comprises a first antenna 14 'to be.

When recording or reading information on the IC 12 'of the IC card 10' as described above, a signal must be applied to the first antenna 14 'from the outside in a non-contact manner.

In detail, when a control signal is applied to the first antenna 14 'from the outside, the power component included in the applied control signal is processed and used as an operating power source of the IC 12', and the control signal. The signal component of is used to write, read, or update data in the IC 12 '.

When the IC card 10 'as described above approaches the antenna units 50 and 55 constituting the IC card terminal external identification device according to the present invention at a predetermined distance interval, the data is wirelessly recorded (Write) or You can read or update.

A process of reading and writing data recorded on the IC 12 'of the IC card 10' will be described in order.

The main body parts 60 and 65 operate by an operating power supply voltage Vcc applied from the outside, and the processing part 66 constituting the main body parts 60 and 65 constitutes the antenna parts 50 and 55. If there is no data received from the IC card 10 'in the second antenna 35, that is, in a standby state, a control signal called a standby state is transmitted to the DC voltage generator 68 or the pulse generator 69. Print each.

Referring to FIG. 2, an example will be described in more detail. The DC voltage generator 68 receives a corresponding control signal of the atmospheric display output from the processor 66, thereby providing a low level of DC. ) The voltage signal Va is output, and the low level DC voltage signal Va is applied to the antenna unit 50 through the second coil L2 and the coaxial cable 70.

The low level DC voltage signal Va is supplied to the display unit 80 and the voltage discriminating unit 52 as an operating power source, and the voltage discriminating unit 52 is a DC voltage applied from the main body unit 60. The level of the signal Va is determined.

As a result of the DC voltage level discrimination of the voltage discriminating unit 52, it is confirmed that the voltage level is low, and a signal for turning on the second transistor Tr2 is output to the base terminal, whereby the second transistor Tr2 is output. (Turn On) is turned on, the second LED (LED2) 86 is to emit light, it is possible to easily identify that the IC card terminal is waiting from the outside.

When the IC card 10 'is brought close to the second antenna 35 of the antenna unit 50 in the above standby state, the second antenna 35 receives the corresponding data from the IC card 10'. The read data is applied to the receiver 64 through the coaxial cable 70 and the fifth capacitor C5, and the receiver 64 outputs to the processor 66.

After the appropriate processing is performed by the processing section 66, if correction is necessary, the data is applied to the transmission section 62.

The transmitter 62 applies the fourth capacitor C4 and the coaxial cable 70 to the second antenna 35, and the second antenna 35 transmits the corresponding data in a non-contact manner to the IC card 10 '. )

In addition, when the data transmission / reception with the IC card 10 'is normally completed, the processing unit 66 outputs the control signal Sb to the DC voltage generator 68 so that the DC voltage generator 68 A high level signal Vb is output as the status signal Sa, and the signal is discriminated from the display unit 80 through the second coil L2, the coaxial cable 70, and the first coil L1. It is applied to the part 52, respectively.

As described above, the state signal Sa of the high level Vb is applied to the display unit 80 and the voltage discriminator 52 as an operating power source, and the high level is confirmed by the voltage discriminator 52. By outputting a signal for turning on one transistor Tr1 to the base of the first transistor Tr1, the first LED (LED1) 84 of the display unit 80 emits light, and the buzzer 82 By operating) to generate a sound, it is possible to confirm that data transmission and reception is normally completed from the outside.

The processing unit 66 outputs the high level DC voltage signal Vb as the state signal Sa as described above for a predetermined time and then outputs the low level DC voltage signal Va again to the state signal Sa. By doing so, it informs that it has returned to the standby state.

At this time, when the processing unit 66 of the main body 60 does not normally transmit and receive the IC card 10 'and the corresponding data, that is, an error occurs in the data transmitted or received, or the IC card 10'. ), The first LED (LED1) 84 is intermittent and continuous by outputting the high-level DC voltage signal (Vb) as intermittently and continuously as a pulse signal. At the same time, the buzzer 82 generates sound signals intermittently and continuously.

By the intermittent and continuous light emission and sound signal as described above, it can be easily identified that the data was not normally transmitted and received between the IC card 10 'and the IC card terminal from the outside. By adjusting the DC voltage generator 68 and the voltage discriminator 52, the high level Vb and the low level Va may be interchanged.

3 and 4, when another example is described in more detail, when the main body 65 is in a standby state capable of receiving data from the IC card 10 ′, the processing unit By the corresponding control signal Sb of 66, the pulse generator 69 outputs the standby state pulse and signal of FIG.

The standby state signal outputs only one pulse signal at a predetermined time period T.

The standby state signal is applied to the power supply unit 100 through the second coil L2 and the coaxial cable 70 and is input to the display unit 90 via the first coil L1.

The power supply unit 100 rectifies and directs a standby state signal applied from the main body unit 65 and outputs it to an operating power source for operating the display unit 90, through the first coil L1. The wait state signal applied to the display unit 90 counts how many pulses are included in the period T by the counter 92.

When one pulse is counted by the counter 92, the counted value is inputted and interpreted by the decoder 94, and then the corresponding control signal in the standby state is output to the display 96.

The signal displayed on the indicator 96 may vary depending on the application, and may include letters, numbers, pictures, images and images, and sound.

As in the above description, when the main body 65 normally transmits and receives data with the IC card 10 ', the pulse generator 69 generates two pulses during the period T. The status signal is applied to the power supply unit 100 through the coaxial cable 70 and detected as a power supply. The counter 92 of the display unit 90 received through the first coil L1 counts the number of pulses and the decoder. By interpreting at 94 and outputting the corresponding signal to the indicator 96, the indicator 96 displays the corresponding signal in the normal state.

In addition, when an error (Error) occurs in data transmission or reception, or when the IC card 10 'is malfunctioning, the pulse generator 69 continuously n pulses as shown in FIG. 4 during the period T. Generates and outputs an error status signal consisting of:

The error state signal as described above is detected by the power supply unit 100 as a power source, applied to the display unit 90, counted by the counter 92 of the display unit 90, and interpreted by the decoder 94. By the relevant display by the display 96, the data processing state can be easily identified from the outside.

As described above, the present invention has a convenient effect that the IC card terminal can readily check the standby state for processing data immediately, a normal state for completing data processing normally, and an error state for which data processing cannot be performed from the outside.

In addition, since the display unit of the antenna unit is used as a power source for operating the display unit using the control signal output from the main body unit, the antenna unit can be made simple and compact, and there is an industrial use effect of reducing the failure rate.
