[FIG. 11] (a) is a partial cross-sectional view of a state where the card-shaped electronic device is inserted into an electronic device, and (b) shows a state of being removed. In the figure, reference numeral 1 denotes a wire ring of an external signal transmitting unit of an electronic device, and 2 denotes a U-shaped cover. Reference numeral 3 is a card-shaped electronic device main body, and 4 is formed so that both ends thereof are exposed on the front and back surfaces of the card electronic device main body and are substantially flat on both sides, and a signal or power transmission line is formed thereon. This is a core for transmitting an internal signal having a wheel 5. Both ends of the internal signal transmitting coil 5 are connected to a printed wiring (not shown) formed on the printed wiring board 6 to connect the electronic components 7 and 7'to form a circuit, thereby forming a circuit. .

Adhere to each other to form a magnetic closed circuit, resulting in a single transformer. Therefore, the signal or power applied to the line wheel is efficiently transmitted to one of the opposite line wheels in a state where there is little crosstalk and signal delay. Further, since the inside of the card-shaped electronic device is completely sealed, it is not limited to the usage environment.
