Claims

[Claims for Utility Model Registration] (1) A function expansion circuit that operates an expansion function to expand the functions of the main body of an electronic device, and a connection between a function expansion device equipped with an expansion function as an external device and the electronic device. An electronic device connection board having an interface function, characterized in that it is equipped with an interface function circuit for ensuring compatibility. (2) a first connector for connecting to the main body of the electronic device; a second connector for connecting to a function expansion device having an expansion function as an external device; and a connection between the electronic device and the first connector. a function expansion circuit connected to the function expansion device and operating the expansion function; connected to the function expansion device via the second connector; 2. The electronic device connection board having an interface function according to claim 1, further comprising an interface function circuit for ensuring connection compatibility with electronic devices. (3) a first connector for connecting to an electronic device main body; a second connector for connecting to a first function expansion device having an expansion function as an external device; and a first connector for connecting the electronic device to the first function expansion device. a function expansion circuit connected to the function expansion device through the connector and operating the expansion function; an interface function circuit for ensuring connection compatibility between the expansion device and the electronic device; and a second function expansion device equipped with an expansion function as an external device to extend the function of the function expansion circuit. The electronic device connection board having an interface function according to claim 1, further comprising a third connector for connection.
