<p>PROBLEM TO BE SOLVED: To provide a cordless mouse by removing a cord for a mouse which is troublesome for operation, and to solve various problems selected to the regulations of the Wireless Telegraphy Act, inter-mouse interference, the life of a battery for driving the mouse, etc. SOLUTION: A mouse mat conventionally used as a mouse ball slip stop is used as a receiving mat 7 and magnetically connected to a cordless mouse 6 to transmit mouse information. Since positional relation between the mat 7 and the mouse 6 is restricted in the method, the quantity of transmission power attenuation between both the mat 7 and mouse 6 is restricted. The mat 7 is provided with a conductor plate short ring to reduce interference in the mat 7. Since the mouse ball of the mouse 6 is used also as a high frequency spherical magnetic core, a change in the quantity of attenuation due to the positional relation between the mouse 6 and the mat 7 can be reduced.</p> |
