Background art
- Non-contact IC cards are used for automatic lifts at ski slopes, railways, and automatic sorting of luggage.
- Fig. 13 shows an example of a conventional non-contact IC card.
- the IC card 2 shown in FIG. 13 is a one-coil type IC card, and includes a coil 4 used as an antenna, capacitors C1, C2, and an IC chip 8.
- the capacitors C1, C2 and the IC chip 8 are mounted on a film-shaped synthetic resin substrate.
- the substrate on which the capacitors C1, C2 and the IC chip 8 are mounted is referred to as “Tape (Tape Automated Bonding) 10”.
- FIG. 14A shows a cross-sectional view of the IC card 2.
- a synthetic resin core member 12 is sandwiched between a pair of surface materials 14 and 16.
- a tab 10 on which capacitors C1, C2 and an IC chip 8 are mounted is fixed to a surface material 14 exposed in a hollow portion 18 provided in the core member 12.
- the joint between the tab 10 and the IC chip 8 is covered with a sealing material 9 such as epoxy resin.
- the coil 4 is arranged between the surface material 14 and the core member 12. Coil 4 and tab 10 are connected by wire 20.
- FIG. 14B shows a circuit diagram of the IC card 2.
- the IC card 2 receives an electromagnetic wave transmitted from a reader / writer (a writing / reading device, not shown) in a resonance circuit 22 composed of a coil 4 and a capacitor C1, and uses this as a power source.
- the capacitor C2 is a power smoothing capacitor.
- a control unit (not shown) provided in the IC chip 8 decodes the information transmitted by being superimposed on the electromagnetic wave, and responds. The response is made by changing the impedance of the resonance circuit 22.
- the reader Z writer knows the response content by detecting a change (impedance reflection) in the impedance of its own resonance circuit (not shown) due to a change in the impedance of the resonance circuit 22 on the IC card 2 side.
- the use of the IC card 2 does not require a power supply in the card, and allows information to be transmitted and received without contact.
- the IC card 2 is often put in a wallet, a pants pocket, or the like, and may be subjected to a strong bending, twisting, or pressing force.
- the thickness t of the IC card 2 shown in FIG. 14A is a standard size and is not sufficiently thick. Therefore, the rigidity against bending, twisting and pushing is not so large. For this reason, when the IC card 2 receives a strong bending force or the like, the bending becomes considerably large. When such bending occurs, the wire 20 may be broken, or the wire 20 may be disconnected from the coil 4 or the tab 10. Further, in the work of connecting the wire 20 and the coil 4 or the tab 10, a connection failure may occur.
