CONSTITUTION:When an IC card 2 is loaded to a service device 1, the coils 32A and 32B of the connecting part 31 are connected each other to form a closed magnetic circuit. An sine-wave output of an oscillator 12 is transferred to the card 2 through the connecting part, and supplied to such part of the IC card via a rectifying circuit 21 and a stabilizing circuit 22. On the other hand, a microcomputer 15 of the service device 1 transfers the information from a transfer control part 19 or memory 17 to the microcomputer 25 of the card 2 through the connecting part 31. Also, the microcomputer 25 transfers the information in the card to the service device 1 through the connecting part 31.

[Technical background of the invention and its problems] Conventionally, such IC cards have been connected using a so-called connector. That is, the connector is provided with contacts, and the contacts of both the IC card and the external device are mechanically pressed to ensure contact, thereby supplying power and transmitting/receiving information.

However, the contact deteriorates due to deterioration of the environment in which it is used, resulting in increased contact resistance and reduced reliability. Furthermore, since the connector is pressed mechanically, positional accuracy is required for insertion and removal, resulting in poor operability. Furthermore, the number of insertions and removals is limited, making it unsuitable for services that require frequent insertion and removal.

However, as a means of securing power, I! i! When a battery is used, the battery has a limited lifespan and needs to be replaced, and if the memory is volatile, the information in the IC card may be destroyed during replacement. In addition, when using a photocoupler to send and receive signals, the way the photocoupler operates differs depending on the usage environment (for example, day and night), which may lead to erroneous transmission.
In order to solve this problem, there is a problem that requires some ingenuity in sensitivity settings, and neither of these is desirable.

On the other hand, information transmission and reception is performed as follows. The microcomputer 15 in the device 1 is operated by input from an operation section (not shown) or from a transmission control section 18 based on a signal from a communication line, or by input from a memory 17.
When transmitting information to the IC card 2 based on information stored therein, the information is transmitted to the BPF 33B via the burst signal generation circuit 16. This signal is supplied to the coil device 32B of the transformer 32 as a band signal of center frequency f2 by the BPF 33B. Therefore, an output is generated from the coil device 32A in the IC card 2, and this output is sent to the BPF 34.
By passing through B, only the band signal of 2 at the center frequency is extracted, and this is sent to the rectifying and smoothing circuit 23. The received information is taken into the microcomputer 25 via the stabilizing circuit 24, and by the control operation of the microcomputer 25, the received information is written into the memory 27 or displayed on a display section (not shown) or the like. Conversely, when transmitting information from the IC card 2 to the service providing device 1 side, the data stored in the memory 27 by the operation of the microcomputer 25 or the information input by the user by operating an operation unit (not shown) is transmitted. When outputted via the burst signal generation circuit 26, this transmission signal passes through the BPF 34B in the coupling unit 31 and is supplied to the transformer 32 as a band signal with a center frequency (□ number f2.
The frequency f2 signal that has passed through 33B is sent to the rectifier and smoothing circuit 13.
Stabilization [11G14. It is sent to the microcomputer 15 and stored in the memory 17, or sent to an external device via the transmission control section 18 and the communication line 19.

In this way, even if the power supply signal and the information transmission signal are superimposed and supplied to the transformer 32 in the coupling unit 31, they are separated by the filters 34A and 34B in the IC card 2, and one is used as the power supply side signal. The information is processed and used as a signal on the information transmission side, and when transmitting information from the IC card 2 to the service providing device 1, the transmission can be performed accurately and easily by simply switching between transmission and reception.
