In general, a computer is divided into a main body, a monitor, and a keyboard, and since the monitor and the keyboard are used in a state in which the main body and the wire are connected to each other, the distance that the keyboard can move from the main body is extremely limited. The disadvantage of not being able to maintain the correct posture is that the keyboard must be used in space.

That is, since the main body and the keyboard should always be in close proximity to each other, the space should be used narrowly, which is inconvenient and difficult to store because the keyboard cannot be moved freely. In addition, because the existing keyboard is connected to the computer main body with a cable, the surrounding area of the computer due to the cable is complicated, and the aesthetic appearance is unsightly. It fell to the ground and the device was damaged due to the impact.

Infrared Rays (IR) To the PC. At this time, the coordinate signal according to the user's movement of the mouse linked to the wireless keyboard is also transmitted to the PC as IR.

As such, a separate receiver is required to transmit each signal transmitted from the keyboard and the mouse to the PC. That is, the receiver includes a built-in receiver built into the PC, and an external receiver used by inserting a jack into the PC.

Among them, the built-in receiver has to manufacture a separate computer main body that is designed in the main body of the board with complex circuits in order to simultaneously receive each signal transmitted from the keyboard and the mouse. This increases the price of the main body of the computer. Or, there was a cumbersome problem that the user has to purchase a separate computer body.

Therefore, there is a need for an apparatus capable of automatically recognizing each signal transmitted from a wireless keyboard and a mouse by making a separate inexpensive external receiver while using the existing computer main body. In particular, it was necessary to implement a circuit so that the external receiver can automatically recognize the keyboard port of the computer main body, the PS / 2 mouse port and the serial mouse port.

Accordingly, the present invention has been made in view of the above-described needs, the object of which is to produce a wireless keyboard and a receiver to automatically recognize that the PS / 2 keyboard line, PS / 2 mouse line and serial mouse line is connected to the PC main body; An object of the present invention is to provide a method and apparatus for automatically recognizing a PS / 2 mouse and a serial mouse to provide a PC with a signal transmitted from the mouse.

In order to achieve the above object, in the present invention, an automatic recognition device of a PS / 2 mouse and a serial mouse includes a wireless keyboard that transmits a code signal and a coordinate signal of a mouse according to a user pressing a desired button in infrared; A personal computer for outputting code signals transmitted from the wireless keyboard and coordinate signals of the mouse to the monitor; After automatically recognizing that the PS / 2 keyboard line, PS / 2 mouse line, and serial mouse line are connected to the personal computer, the personal computer receives code signals and mouse coordinate signals from the wireless keyboard through the recognized lines. It includes a receiver to provide.

In addition, another aspect of the present invention for achieving the above object is to check the state of the Rx check unit and the RTS check unit in the serial mouse line; Confirming that the PC system is selected as a serial mouse if the states of the Rx check unit (low) and the RTS check unit are high in the checking step; If the state of the Rx check unit and the RTS check unit is low in the checking step, the connection waiting state; Monitoring the state of the RTS check unit in the connection waiting state to determine whether the state is changed to a high state; If the state of the RTS check unit is changed to a high state in the judgment step, the serial ready data is provided to the personal computer, and if the state of the RTS check unit is held high, the serial mouse line is connected.
