Subminiature image input device having double coupling structure

Abstract

An image input device, such as a subminiature image input device, having a double coupling structure is disclosed. The image input device is modularized to be portable and have various functions such as power charging, wired-wireless data communication, and data storage. Further, the image input device can be easily and selectively coupled to other external devices to extend the functionality thereof. The image input device includes a main module and a sub-module. The main module includes a camera unit, configured to capture an image, and a pin terminal unit, which comes into contact with a pattern electrode and generates a first operation signal to operate the camera unit. The sub-module includes the pattern electrode, which comes into contact with the pin terminal unit and generates the first operation signal, and a power signal to activate the camera unit.

Dependencies are inferred from the claim text.
