PROBLEM TO BE SOLVED: To reduce the escape of magnetic flux and to improve the efficiency of electromagnetic transaction by forming a magnetic passage part to be passage for magnetic flux between a card side coil part and a reader side coil part. SOLUTION: The magnetic passage part 8 is formed out of a magnetic substance to have a U-shaped cross section and integrally fixed on a frame 1B to be a base part. The passage part 8 holds a card raveling route from its upper and lower sides and is arranged on a part corresponding to the reader side coil 26. Namely, the passage part 8 is arranged on a position capable of holding the card side coil 5 and the reader side coil 26 in its inside when a proximity card C1 is stopped on a traveling stop position. When a voltage is impressed to the coil 26 and an IC chip, magnetic flux generated in the coil 26 is transmitted to the coil 5, voltage changed correspondingly to information is electromagnetically transduced and electromotive force is generated. The magnetic flux generated on the coil 26 is transmitted to the coil 5 and and formed into a closed loop, through the presage part 8. |
