Description

  The present invention relates to a wireless integrated operation device that can be connected to a main body of a personal computer for general use and can operate the main body wirelessly using a notebook keyboard or display.

  Generally, a personal computer is roughly classified into a notebook computer in which a liquid crystal display, a keyboard and a CPU are integrally formed, and a desktop computer in which a display, a keyboard, and a computer main body including a CPU are separately provided.

  The notebook computer is small and lightweight, and thus has excellent portability. The desktop computer is inferior in portability, but has internal circuit devices such as a CD-ROM, a HDD (magnetic disk device), various interface boards, and the like. It is known that it has a characteristic that replacement of a motherboard or CPU is easy.

On the other hand, as a desktop computer according to the related art, a computer that wirelessly connects a computer main body and peripheral devices such as a keyboard as described in Patent Documents 1 to 4 below is known.

However, none of these technologies considers wireless security, and malfunctions due to information leakage or interference. There was such a problem. In addition, a dedicated computer main body and a dedicated peripheral device are set as a set, which lacks versatility and has a drawback that it cannot be directly applied to a personal computer used by general individuals. Further, the display and the keyboard are separated from each other, so that there is a problem that portability is lacking.

  The problem to be solved by the present invention is to eliminate the above-mentioned disadvantages of the prior art without deteriorating the advantages of the desktop computer.

  In order to solve the above-mentioned problem, the present invention connects to a screen display signal connector / keyboard connector / mouse connector / speaker connector provided as standard in a computer main body, and transmits and receives signals input / output to / from these terminals. And an integrated operation device that performs encrypted wireless communication with the communication device and integrates a display / keyboard / pointing device / speaker like a notebook computer.

A separating / combining unit that separates the image signal into a mouse signal and outputs the signal to a computer main body; and an encrypting unit that encrypts at least the image signal and decrypts a received keyboard signal. Further, the integrated operation device includes a communication unit that receives a signal transmitted from the communication device, a signal that is received by the communication unit is separated into a screen display signal and a speaker signal, and the signal is output. A separating / synthesizing unit for synthesizing the signal and the pointing device signal and outputting the synthesized signal to the communication unit, an encryption unit for encrypting at least the keyboard signal and decoding the received image signal, and controlling the display using the screen signal. A display control unit for performing the operation, a display unit for displaying an image based on an image signal provided from the display control unit, a speaker unit for reproducing a speaker signal output from the separation / synthesis unit, and a keyboard for the separation / synthesis unit. A keyboard unit that integrally stores a keyboard unit that outputs a signal, and a pointing device that outputs a pointing device signal to the separation / combination unit. It characterized the type of configuration.

  According to the present invention, the use place of the desktop computer by the user can be freely moved within the communicable range of the wireless communication without being limited to the installation place of the computer main body. Further, when the user desires to improve the performance of the computer main body, the system performance can be improved by exchanging parts of the computer main body while using the integrated operation device as it is. Further, since encryption is performed in wireless communication, information leakage and interference with other devices can be prevented. That is, the user can obtain the advantages of space saving and portability comparable to a notebook computer without losing the advantages of expandability and versatility of the desktop computer.
