Patent ID: 7506814

Claim:
A card reader which conducts reading and writing on a non-contact IC card having a radio communication function, by means of radio communication with the non-contact IC card, the card reader comprising: a frame member having an insertion path to guide the non-contact IC card inserted into a main body to a card data reading position; and an antenna substrate having a coil-shaped circuit pattern formed thereon to function as an antenna, the antenna substrate being attached to the frame member so as to cause the coil-shaped circuit pattern to be opposed to the non-contact IC card when set in the card data reading position, wherein the antenna substrate has an opening inside the coil-shaped circuit pattern, and wherein the antenna substrate is located or disposed underneath the non-contact IC card inserted into the card reading position; and a card data reader-writer disposed so as to be opposed to the antenna substrate, wherein the non-contact IC card or a contact IC card fits in the card data reading position between the data card reader-writer and the antenna substrate, and wherein the card reader-writer is disposed so as to be connected to contact terminals formed on a surface of the contact IC card.
