Abstract:
1. A card device configured to be inserted into and ejected from a host device in a first direction, comprising: a first housing including a leading edge, which is inserted into the host device, a trailing edge opposite to the leading edge, a side edge extending between the leading edge and the trailing edge and concave regions formed on a surface surrounded by the leading edge, the trailing edge, and the side edge; a first electrode array including first electrodes linearly aligned in a second direction along the leading edge; and a second electrode array including second electrodes aligned in the second direction between the first electrode array and the trailing edge, wherein the second electrodes include an electrode shifted from the first electrodes in the second direction, wherein the concave regions include a first concave region extending from the leading edge toward the trailing edge, and a second concave region closest to the side edge among the concave regions, wherein the first and second electrode arrays are situated in the first concave region, wherein a number of the second electrodes situated in the first concave region is different from a number of the first electrodes situated in the first concave region, wherein the second concave region is adjacent to the first concave region and extends from the leading edge toward the trailing edge, wherein the second concave region includes a first region, which is adjacent to the first electrodes in the first concave region, and a second region, which is adjacent to the second electrodes in the first concave region, wherein at least one of the first electrodes of the first electrode array is situated in the first region of the second concave region, and wherein no electrodes are situated in the second region of the second concave region.
