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. ## Claims ### Claim 1 An image input device, comprising: a main module comprising a camera unit configured to capture an image, and a pin terminal unit configured to generate a first operation signal to start controlling the camera unit upon contacting a pattern electrode; and a sub-module comprising the pattern electrode configured contact the pin terminal unit to cause generation of the first operation signal, wherein the main module and the sub-module are configured to be removably physically coupled to each other, and wherein the first operation signal and a power signal to activate the camera unit are generated when the main module and the sub-module make electrical contact that is caused at least in part by a physical coupling between the main module and the sub-module. ### Claim 2 (depends on 1) The image input device of claim 1, wherein the main module further comprises a first processing unit configured to control power of the camera unit upon receiving the first operation signal and to control image information obtained by the camera unit. ### Claim 3 (depends on 1) The image input device of claim 1, wherein the pin terminal unit includes at least one of a charging terminal, a data communication terminal and a signal terminal. ### Claim 4 (depends on 2) The image input device of claim 2, wherein the main module further comprises a coupling detection unit configured to generate a second operation signal to start controlling the camera unit from an outside upon contacting a detection means, and the sub-module further comprises the detection means configured to cause generation of the second signal upon being coupled to the coupling detection unit, and wherein the first processing unit is configured to control the camera unit after receiving at least one of the first operation signal and the second operation signal. ### Claim 5 (depends on 4) The image input device of claim 4, wherein the first processing unit is configured to control the camera unit after receiving both the first operation signal and the second operation signal. ### Claim 6 (depends on 5) The image input device of claim 5, wherein the first processing unit comprises: a memory unit configured to store image information obtained by the camera unit; a charging unit configured to be charged through the pin terminal unit; and a control unit configured to control the camera unit after receiving at least one of the first operation signal and the second operation signal. ### Claim 7 (depends on 1) The image input device of claim 1, wherein the main module and the sub-module further comprise respective magnets generating magnetic force, the magnets being disposed such that opposite poles face each other. ### Claim 8 (depends on 4) The image input device of claim 4, wherein the coupling detection unit comprises one of a contact signal terminal, a magnetic sensor, a proximity sensor, and a radio recognition sensor. ### Claim 9 (depends on 1) The image input device of claim 1, wherein the pattern electrode is configured to have a conductive plate shape corresponding to a pin terminal that can generate the first operation signal. ### Claim 10 (depends on 1) The image input device of claim 1, wherein the pattern electrode is patterned to have a concentric circle shape, or is patterned to have a pin shape at a position corresponding to the pin terminal unit. ### Claim 11 (depends on 1) The image input device of claim 1, wherein the sub-module further comprises a second processing unit, including at least one of a location tracking unit configured to receive location information, a memory unit configured to store the location information and backup data of the main module, a wired-wireless communication means for communicating with an external communication means in a wired or wireless manner and a charging unit configured to provide power to the main module. ### Claim 12 (depends on 1) The image input device of claim 1, wherein the sub-module further comprises a mounting part to which the main module is mounted such that the main module is prevented from being removed from the sub-module. ### Claim 13 (depends on 1) The image input device of claim 1, wherein the sub-module further comprises an installation means for fastening the sub-module at a desired position. ### Claim 14 (depends on 1) The image input device of claim 1, wherein the sub-module further comprises a connector configured to be connected to an external auxiliary device for extension of functionality. ### Claim 15 (depends on 1) The image input device of claim 1, wherein the sub-module is configured such that a pin terminal unit is formed on a surface of the sub-module other than a surface thereof on which the pattern electrode is formed. ### Claim 16 (depends on 14) The image input device of claim 14, wherein when the main module is coupled to the sub-module and connected, by the connector of the sub-module, to a display means, which is the auxiliary device, image information of the main module is output to the display means. ### Claim 17 (depends on 16) The image input device of claim 16, wherein the display means comprises any one selected from among a smartphone, a computer, and an imaging device.
