<p>PROBLEM TO BE SOLVED: To reduce the number of parts to be arranged on the periphery of click buttons of a mouse and the cost of the mouse. SOLUTION: A button plate 2 is an elastic plate-like member side-supported by fixing a base end part to the body 1 of the mouse by adhesives or the like and is constituted of uniting two click buttons to a body. The plate 2 is divided into two parts by a groove 2d from its head part up to an intermediate part and the divided head parts are respectively expanded to form button tops 2a, 2b. The intermediate part of the plate 2 is easily elastically deformed by a groove 2e formed on its lower face, and when the tops 2a, 2b are depressed, the intermediate part is distorted, the tops 2a, 2b are moved down and projected parts 2c formed on the lower face of the tops 2a, 2b depress switches 4a, 4b to turn on them. When fingers are separated from the tops 2a, 2b, the tops 2a, 2b are lifted by the elastic force of the intermediate part and returned to the original positions.</p> |
