A system for transferring the operation of a device to an external apparatus, comprising:

• a device applicable to a wireless cell phone or a PDA (personal digital assistant) being coupled with a liquid crystal display, a mini projector, a keyboard and a mouse, through a signal transmission, an image of the device being transmitted to the liquid crystal display to magnify and display the image, or through the mini projector, the image being magnified and projected on a projector screen;
• the keyboard being connected with a central processing unit of the wireless cell phone or the PDA and connected with the mouse, enabling the liquid crystal display to display the cursor of the keyboard or the mouse at a relative position of the image for adding, amending, or saving direct;
• the central processing unit being built in the wireless cell phone or the PDA and installed with a software driver program, the software driver program enabling the CPU to magnify and display the image on the liquid crystal display via the signal transmission, the cursor of the keyboard or the mouse being displayed at the relative position of the image for direct operating on the image corresponding to the operation of the wireless cell phone or the PDA;
• thereby, through the central processing unit, the image of the wireless cell phone or the PDA being transmitted to the liquid crystal display to magnify and display the image, the keyboard or the mouse being adapted to direct operate the wireless cell phone or the PDA;
• wherein, the mini projector is provided with the projector screen instead of the liquid crystal display, a universal serial bus (USB) signal transmission line is connected with the wireless cell phone or the PDA, such that the image of the wireless cell phone or the PDA is projected on the projector screen through the mini projector, and the cursor of the keyboard or the mouse is displayed at the relative position of the image for direct operating the image through the universal serial bus (USB) signal transmission or a Bluetooth wireless transmission device.
