US Patent 7506814 Card reader

A card reader which makes it possible to read card data from a non-contact IC card, discharge a foreign substance inserted from a card insertion slit, sufficiently ensure the degree of freedom in design, and sufficiently prevent the size of the apparatus main body from becoming large. A coil-shaped circuit pattern is formed on an antenna substrate used as an antenna for radio communication with a non-contact IC card. A part located inside the coil-shaped circuit pattern is cut out to form an opening. Even if the antenna substrate is disposed below the card reader main body, therefore, a foreign substance such as a coin inserted from an insertion slit may be discharged from the opening of the antenna substrate.
