主权项 1. A wireless communication system comprising: a wireless communication apparatus comprising a plurality of differential coil pairs that respectively transmit and receive differential signals to and from a plurality of external differential coil pairs, through magnetic coupling, a marker portion having a predetermined relative position with respect to the differential coil pairs, and a first electrode section that is provided at a position where the differential coil pairs are not arranged, wherein one coil in a first differential coil pair among the differential coil pairs is provided at a distance from each of two coils of a second differential coil pair among the differential coil pairs that is less than or equal to a distance between the two coils of the second differential coil pair, and the other coil of the first differential coil pair is provided at a distance from each of the two coils of the second differential coil pair that is greater than the distance between the two coils of the second differential coil pair; and an access apparatus that communicates with the wireless communication apparatus, and comprises: the plurality of external differential coil pairs, a reference position portion having a predetermined relative position with respect to the external differential coil pairs and operable to engage with the marker portion, a second electrode section that is operable to contact the first electrode section so that the first electrode section and the second electrode section are electrically connected, and an aligning section that adjusts the relative positions of the marker portion and the reference position portion, wherein when the first electrode section is connected to the second electrode section, the relative position of the differential coil pair and the corresponding external coil pair is held so that a magnetic coupling between the differential coil pair and the corresponding external coil pair is achieved.
