摘要：
In an external medium communication system including a non-contact card 300, which is an external medium, and a card communication device 400, which is a communication device, the non-contact card 300 includes a conductive unit 320, and the card communication device 400 includes a detection antenna unit 420 including a detection output antenna 421 and a detection input antenna 422. When the external medium 300 is mounted in a predetermined position, the card communication device 400 detects that the non-contact card 300 is in the predetermined position by detecting that the detection output antenna 421 and the detection input antenna 422 are coupled by electromagnetic induction across the conducting unit 320.
