    • A card processor which can substantially reliably prevent magnetic data recorded in a magnetic card and can remarkably enhance security. In the card processor, two radiation sources radiate disturbing magnetic fields outside of an insertion slot. A disturbing magnetic field radiated from one radiation source and a disturbing magnetic field radiated from the other radiation source have different frequencies and intensities. Accordingly, even when a differential head is located at such a position as to be influenced by the disturbing magnetic fields, it is substantially impossible to attain such balance adjustment as to eliminate the influences of the disturbing magnetic fields.
    • 一种能够基本上可靠地防止记录在磁卡中的磁数据并且可以显着增强安全性的卡处理器。 在卡处理器中,两个辐射源辐射出插入槽外的干扰磁场。 从一个辐射源辐射的干扰磁场和从另一个辐射源辐射的干扰磁场具有不同的频率和强度。 因此,即使当差动头位于受到干扰磁场影响的位置时,实质上不可能实现这种平衡调整,以消除干扰磁场的影响。

    • An insertion-port loop antenna has a wide communication region for a non-contact type IC card inserted into an insertion port of a card reader, etc. An insertion-port loop antenna is mounted in the vicinity of an insertion port, through which a non-contact type communication medium is inserted. The insertion-port loop antenna comprises two loops. An upper loop is arranged above a long side of the insertion port. A lower loop is arranged below the long side of the insertion port. The two loops are opposite to each other in a direction of winding. Thereby, magnetic flux is generated between the upper loop and the lower loop. The magnetic flux is generated in front of the insertion port. Therefore, it is possible to begin communication before the non-contact type IC card is inserted into the insertion port.
    • 插入口环形天线具有用于插入读卡器插入口等的非接触式IC卡的宽通信区域。插入口环形天线安装在插入口附近, 插入非接触型通信介质。 插入口环形天线包括两个环。 上部环路布置在插入口的长边上方。 下部环设置在插入口的长边的下方。 两个环在绕组方向上彼此相对。 由此,在上回路和下回路之间产生磁通。 在插入口前面产生磁通。 因此,可以在将非接触型IC卡插入插入口之前开始通信。
