MOUSE WITH PAD

A mouse embedded with a mouse pad is provided to enable a user to keep/carry the mouse and the mouse pad easily in any place by combining the mouse and the mouse pad in one body. A lower housing includes an optical sensor(110). A mouse pad(150) is moved in four directions on the optical sensor and reflects light irradiated from the optical sensor. A supporter supports the mouse pad moved to four directions. An upper housing(102) is coupled with the lower housing, and forms an operation hole(102a) at a position corresponding to the mouse pad. The supporter includes a lifting plate(120) having a penetration hole(121) passing the light of the optical sensor, supporting the mouse pad, and lifted up/down on the optical sensor, a plurality of first springs fixing a lower end to the lower housing and fixing an upper end to the lifting plate, a plurality of supporting blocks supporting the pad on the lifting plate, and a second spring fixing one end to the upper or lower housing, and fixing another end to the supporting blocks.
