The purpose of the present invention is to expand or change a function by independently developing a core device running an OS and a program executed by the OS and connecting the core device to an external device. An electronic device that is an existing complete product must be replaced with a new product when a new technology exists. However, which is the burden of a user for purchase as well as causes a serious problem such as industrial waste. To solve the problems, an independent product is developed by configuring, in a case (110), a CPU (120), a storage unit (130), a power interface unit (140), an input interface unit (150), and an output interface unit (160) that are core parts of an electronic device, and is connected to, built in, and coupled to other external devices. Thus, the present invention can extend the lifetime of input devices (keyboard, mouse, touch device, GPS, communication device, microphone, camera, scanner, etc.) and output devices (display, speaker, motor controller, etc.) used as external devices, thereby lowering the costs of purchase of a new product and upgrade of users and reducing a serious problem such as industrial waste. |
