Can be switched automatically. In addition, when the smartphone 300 is coupled to and connected to the second docking unit 21, the controller 30 may select a specific function of the smartphone 300 to be automatically performed. That is, for example, the smartphone 300 may be coupled to the second docking unit 21 to be connected to the second docking unit 21 so as to set a preferred function such as an electronic album function or a music playback function in advance. Here, if necessary, the smart phone 300 may be installed with a program in the form of an application for communicating with the control unit 30.

Alternatively, as in the above-described first embodiment, an additional mode switching key 73 may be further provided to switch to the output mode.

The second docking unit 21 may further include a second power output terminal 25 for supplying power to the smart phone 300. Therefore, after the smartphone 300 is coupled to the second docking unit 21, the use and charging of the smartphone 300 can be performed at the same time. The second power output terminal 25 may be provided integrally with the second communication terminal 23 as in the above-described first embodiment.

Like the first docking unit 11 of the first embodiment, the second docking unit 21 may be provided to be adjustable in correspondence to the size and shape of the smart phone 300.

Accordingly, the smart phone detachable input device according to the second embodiment of the present invention having the above-described structure may be equipped with a smart phone in the second docking unit so that various functions of the smart phone can be used simultaneously with charging, such as a note PC. There is no need to carry other devices.

The smartphone detachable input device 1 according to the third embodiment of the present invention further includes a display unit 100 detachably provided at the case 70. Therefore, in the present embodiment, various functions of the smartphone 300 may be implemented through convenient input means and output means such as a note PC, and at the same time, the smartphone 300 may be used as a touch pad.

The display unit 100 and the input device 1 may be connected in various ways. For example, as shown in the drawing, the display unit 100 may be connected through the output terminal 40. It may also be directly connected through the hinge portion to be connected. Or, it may be connected by a wireless (Bluetooth or WIFI, etc.) scheme.

In this case, information output through the touch screen 301 or input through the touch screen 301 from the smart phone 300 connected to any one of the first communication terminal 13 or the second communication terminal 23. One or more of the mouse pointer control signals and the key signal may be output.

In the present embodiment, unlike the first embodiment described above, the smart phone 300 performs a function as a host. The input means for implementing this is the keypad 71 and the output means uses the display unit 100. will be.

Therefore, since various parts such as a central processing unit or a memory may be omitted in the input device 1, the manufacturing cost may be significantly reduced, and the use of the smartphone 300 may also be very convenient.
