         [0124]    In process 1, the mouse transmission unit a  310  transmits an “activation” signal to the receiving unit a  220  of the receiver a  200  and in the process 1, the control unit a  230  of the receiver a  200  that receives the “activation” signal from the receiving unit a  220  of the receiver a  200  turns on the LED a  250  and when the mouse input or the keyboard input is received, the control unit a  230  transmits the received mouse input or keyboard input to the computer a  100 . 
         [0125]    In process 2, the mouse transmission unit b  311  transmits a “deactivation” signal to the receiving unit b  221  of the receiver b  201  and in the process 2, the control unit b  231  of the receiver b  201  that receives the “deactivation” signal from the receiving unit b  221  of the receiver b  201  turns off the LED b  251  and when the mouse input or the keyboard input is received, the control unit b  231  disregards the received mouse input or keyboard input without transmitting the received mouse input or keyboard input to the computer b  101 . 
         [0126]    In process 3, after processes 1 and 2 are executed, the mouse transmission unit b  313  becomes in a “non-operation state”. Here in, even in skipping the process 3, it works normally. But, it can reduce a battery consumption of the wireless mouse little more. 
         [0127]    When states after processes 1, 2, and 3 are performed are organized, the mouse transmission unit a  310  is in an “operation standby state”, the receiver a  200  is in an “activation” state, the LED a  250  is turned on, the mouse transmission unit b  311  is in the “non-operation state”, the receiver b  201  is in the “deactivation” state, and the LED b  251  is turned off 
         [0128]    In the states, when the mouse input or the keyboard is received, only the computer a  100  operates. 
         [0129]    Unlike this, when the channel selection button b  361  is pressed, the mouse control unit a  330  performs the following process. 
         [0130]    In process 4, the mouse transmission unit b  311  transmits an “activation” signal to the receiving unit b  221  of the receiver b  201  and in the process 4, the control unit b  231  of the receiver b  201  that receives the “activation” signal from the receiving unit b  221  of the receiver b  201  turns on the LED b  251  and when the mouse input or the keyboard input is received, the control unit b  231  transmits the received mouse input or keyboard input to the computer b  101 . 
         [0131]    In process 5, the mouse transmission unit a  310  transmits a “deactivation” signal to the receiving unit a  220  of the receiver a  200  and in the process 5, the control unit a  230  of the receiver a  200  that receives the “deactivation” signal from the receiving unit a  220  of the receiver a  200  turns off the LED a  250  and when the mouse input or the keyboard input is received, the control unit a  230  disregards the received mouse input or keyboard input without transmitting the received mouse input or keyboard input to the computer a  100 . 
         [0132]    In process 6, after processes 1 and 2 are executed, the mouse transmission unit a  310  becomes in a “non-operation state”. 
         [0133]    When states after processes 4, 5, and 6 are performed are organized, the mouse transmission unit b  311  is in an “operation standby state”, the receiver b  201  is in an “activation” state, the LED b  251  is turned on, the mouse transmission unit a  310  is in the “non-operation state”, the receiver a  200  is in the “deactivation” state, and the LED a  250  is turned off. 
         [0134]    In the states, when the mouse input or the keyboard input is received, only the computer b  101  operates. 
         [0135]    The mouse input of the wireless mouse a  300  is transmitted only through the mouse transmission unit which is in the “operation standby state” by the mouse control unit a  330  to be transferred to the receiving unit of the receiver having the same channel and the mouse transmission unit which is in the “non-operation state” does not operate. 
         [0136]    Unlike the wireless mouse a  300 , the keyboard input of the wireless keyboard a  400  is transferred to both the receiver a  200  and the receiver b  201  through the keyboard transmission unit a  410  and the keyboard transmission unit b  411  by the keyboard control unit a  430 , but only the computer of the receiver which is activated operates and the computer of the receiver which is deactivated does not operate. 
         [0137]    The “activation”, the “deactivation”, the “non-operation state”, and the “operation standby state” written in the contents mean states after the corresponding control unit executes the corresponding process according to a specific command signal and are described by matching an original meaning of a term for easy description. 
         [0138]    The “activation” of the receiver means a state in which when the mouse input or the keyboard input is received by the control unit of the receiver through the receiving unit of the selected receiver, the control unit of the receiver transmits the received mouse input or keyboard input to the connected computer to allow the computer to execute the input of the mouse or keyboard and the “deactivation” of the receiver means a state in which when the mouse input or the keyboard input is received by the control unit of the receiver through the receiving unit of the selected receiver, the control unit of the receiver does not transmit the mouse input or the keyboard input to the connected computer and disregards the mouse input or the keyboard input. That is, the deactivated receiver does not operate by the input of the mouse or keyboard except for manipulation of the channel selection button of the wireless mouse. 
         [0139]    The “non-operation state” of the mouse transmission unit means a state in which it is impossible to transmit the mouse input through the corresponding mouse transmission unit except for the signal generated by the channel selection button. 
         [0140]    The “operation standby state” of the mouse transmission unit means a state in which it is possible to transmit the signal generated by the channel selection button and the mouse input through the corresponding mouse transmission unit.

         [0145]    The receiver c  202  is constituted by the receiving unit c  222  that receives the signals transmitted from the mouse transmission unit c  312  and the keyboard transmission unit c  412 , the transmitting unit e 1   214   a  that transmits the signals to the mouse reception unit e  324  and the keyboard reception unit e  424 , an LED c  252  that displays an operation state of the receiver c  202 , and a control unit c  232  that controls the input signal processing and the modules in the receiver c  202 .

         [0153]    In the states, when the mouse input or the keyboard is received, only the computer c  102  operates. 
         [0154]    Unlike this, when the channel selection button d  363  is pressed, the mouse control unit c  332  performs the following process. 
         [0155]    In process 10, the mouse transmission unit d  313  transmits an “activation” signal to the receiving unit d  223  of the receiver d  203  and in the process 10, the control unit d  233  of the receiver d  203  that receives the “activation” signal from the receiving unit d  223  of the receiver d  203  turns on the LED d  253  and when the mouse input or the keyboard input is received, the control unit d  233  transmits the received mouse input or keyboard input to the computer d  103 .

         [0157]    In process 12, after processes 10 and 11 are executed, the mouse transmission unit c  312  becomes in a “non-operation state”. 
         [0158]    When states after processes 10, 11, and 12 are performed are organized, the mouse transmission unit d  313  is in an “operation standby state”, the receiver d  203  is in an “activation” state, the LED d  253  is turned on, the mouse transmission unit c  312  is in the “non-operation state”, the receiver c  202  is in the “deactivation” state, and the LED c  252  is turned off.

The reason is that since the transmitting unit is installed even in the receiver, the status of the deactivated receiver is notified to the wireless keyboard to allow the corresponding transmitting unit of the wireless keyboard to be in the “non-operation state”. In addition, as compared with a unidirectional transmission/reception type, as an advantage of a bidirectional transmission/reception type, the computer may read state values of the wireless mouse and the wireless keyboard to measure the life-span of the batteries of the wireless mouse and the wireless keyboard and diagnose and check defects of the wireless mouse and the wireless keyboard and as necessary, functions to allow the user to perform transmission/reception bidirectionally are inserted to manufacture various products.

         [0171]    When the states progressed after the channel selection button f  365  is pressed, the receiver f  205  is in the “activation” state, the LED f  255  is turned on, the receiver g  206  is in the “deactivation” state, and the LED g  256  is turned off. 
         [0172]    In the states, when the mouse input or the keyboard is received, only the computer f  105  operates. 
         [0173]    When the channel selection button g  366  is pressed, the mouse control unit f  335  transmits an “activation of receiver g” signal to the receiving unit f  225  of the receiver f  205  and the receiving unit g  226  of the receiver g  206  through the mouse transmission unit fg  315 .

The control unit i  238  of the receiver i  208  that receives the “activation of receiver i” signal turns on the LED i  258  and when the control unit i  238  receives the mouse input or the keyboard input, the control unit i  238  of the receiver i  208  transmits the mouse input or the keyboard input to the computer i  108 . Simultaneously therewith, the control unit h  237  of the receiver h  207  that receives the “activation of receiver i” signal turns off the LED h  257  and when the control unit h  237  of the receiver h  207  receives the mouse input or the keyboard input, the control unit h  237  of the receiver h  207  does not transmit the mouse input or the keyboard input to the computer h  107  but disregards the mouse input or the keyboard input.

         [0213]    In process 15, the transmitting unit i  93   a  of the remote controller  2   90   a  transmits the “activation” signal to the receiving unit i  31   a  of the computer i  30   a  and in the process 15, when the control unit i  33   a  of the computer i  30   a  that receives the “activation” signal through the receiving unit i  31   a  of the computer i  30   a  receives the input signals from m input devices, the control unit i  33   a  of the computer i  30   a  transmits the input signals to the computer i  30   a.

         [0217]    Herein, in the contents, in the input device j, the input unit j, and the control unit j, j means arbitrary and is commonly used in  FIGS. 7 and 9 . 
         [0218]    In  FIG. 8 , the number of computers is n, one receiving unit having the same frequency is provided in each computer, and a control unit is provided, which controls the input/output signal processing and the corresponding receiving unit. 
         [0219]    The number of input devices is m, one transmitting unit having the same frequency is provided in each input device, an input unit taking charge of the input is provided, and a control unit is provided, which controls the input/output signal processing and the corresponding modules inside each input device. 
         [0220]    A remote controller  3   80   b  as a tool that connects m input devices to the computer which the user intends to use among the n computers includes a transmitting unit R  81   b , n channel selection buttons to select the channel, and a control unit R  82   b  that controls the input signal processing and the modules in the remote controller  3   80   b.    
         [0221]    The receiving units of n respective computers use the same frequency as a transmitting unit R  81   b  of the remote controller  3   80   b  and the transmitting unit in each of m input devices. 
         [0222]    When a arbitrary channel selection button i  85   b  in the remote controller  3   80   b  is pressed, the control unit R  82   b  of the remote controller  3   80   b  transmits an “activation of computer i” signal to the receiving units of n computers through the transmitting unit R  81   b  of the remote controller  3   80   b  and when a control unit i  33   b  of the computer i  30   b  that receives the “activation of computer i” signal through the receiving unit i  31   b  of the computer i  30   b  receives the input signals from m input devices, the control unit i  33   b  transmits the received input signals to the computer i  30   b.    
         [0223]    A control unit of another computer other than the computer i  30   b  among n computers also receives the “activation of computer i” signal through the corresponding receiving unit, but since the “activation of computer i” signal is not an “activation of the control unit itself” signal, the control unit processes the “deactivation” command signal and disregards the input signals received from m input devices. 
         [0224]    In the state, when the respective signal inputs are received from m input devices, only the computer i  30   b  operates. 
         [0225]    In the contents, when each control unit of n computers receive a signal which is not “activation of the control unit itself” signal in signal generated by the channel selection button, the control unit handles with “deactivation” command.

         [0229]    The receiving units of n respective computers use the same frequency as a transmitting unit R  91   c  of the remote controller  4   90   c  and the transmitting unit in each of m input devices and the transmitting unit B of each of n computers uses the same frequency channel as the receiving unit B in each of m input devices. 
         [0230]    When a arbitrary channel selection button i  95   c  in the remote controller  4   90   c  is pressed, the control unit R  92   c  of the remote controller  4   90   c  transmits an “activation of computer i” signal to the receiving units of n computers through the transmitting unit R  91   c  of the remote controller  4   90   c  and when a control unit i  33   c  of the computer i  30   c  that receives the “activation of computer i” signal through the receiving unit i  31   c  of the computer i  30   c  receives the input signals from m input devices, the control unit i  33   c  transmits the received input signals to the computer i  30   c.    
         [0231]    A control unit of another computer other than the computer i  30   c  among n computers also receives the “activation of computer i” signal through the corresponding receiving unit, but since the “activation of computer i” signal is not an “activation of the control unit itself” signal, the control unit processes the “deactivation” command signal and disregards the input signals received from m input devices. 
         [0232]    In the state, when the respective signal inputs are received from m input devices, only the computer i  30   c  operates. 
         [0233]    In the contents, when each control unit of n computers receive a signal which is not “activation of the control unit itself” signal in signal generated by the channel selection button, the control unit handles with “deactivation” command. 
         [0234]    In the status, when the user inputs the signal by using a arbitrary input device j  70   c , a control unit j  74   c  of the input device j  70   c  transmits the input signal to the receiving unit i  31   c  of the computer i  30   c  through a transmitting unit i  71   c  and the control unit i  33   c  of the computer i  30   c  transmits the input signal received by the receiving unit i  31   c  to the computer i  30   c . The computer i  30   c  verifies and executes an ID to recognize which input device transmits the received input signal. When the input signal executed and processed by the computer i  30   c  is a signal to request a feedback of the input device j  70   c , the control unit i  33   c  transmits the signal executed and processed by the computer i  30   c  to a receiving unit B  72   c  of the input device j  70   c  through a transmitting unit B  32   c  and the corresponding control unit j  74   c  executes and processes the corresponding signal and thereafter, retransmits the executed and processed signal to the computer i  30   c.    
         [0235]    In the contents of the present invention, since unidirectional and bidirectional input devices of a scheme that uses respective different frequencies and a scheme that divides the channels of the same frequency operate independently from each other, the “Sleep Mode” in non-use and the “WakeUp Mode” in use are available and the battery may be thus used for a long time and multiple input devices may be used in the computer desired by the user among multiple computers by the channel selection button. 
         [0236]    The scheme that differentiates the frequency and the scheme that divides the channels at the frequency may be applied to Internet of Things or a wearable device and applied even to a smart device such as a smart phone or a smart pad. 
         [0237]    The two schemes have advantages and disadvantages and when only the disadvantages are described, since a lot of transmitting units and receiving units having different frequencies need to be used in the frequency channel scheme, the number of controlled computers increases, and as a result, it may be complicated in implementing the frequency division scheme and there is a limit in channels which may be divided at the same frequency in the channel division scheme. Those skilled in the art may jointly use both schemes by considering the advantages and disadvantages. 
         [0238]    The channel selection button of the remote controller mentioned in  FIGS. 6, 7, 8, and 9  of the present invention for easy description may be inserted into a arbitrary computer among n computers and inserted into a arbitrary input device among m input devices. 
         [0239]    In addition, n computers and m input devices which are terms mentioned in  FIGS. 6, 7, 8, and 9  are limitedly described for easy description, but the computers may be implemented by n different systems or equipments and the input devices may be implemented even by m different types of input/output devices. 
         [0240]    As described above, detailed exemplary embodiments have been described in the detailed description of the present invention, but a possibility that the technology of the present invention will be easily modified and executed by those skilled in the art is apparent and the modified exemplary embodiments will be included in the technical spirit disclosed in the appended claims of the present invention.
