An optical cursor control device is provided. The optical cursor control device includes a worktable, and an optical mouse moved on the worktable by an operator. The optical mouse has a case. A light guide is disposed at a sidewall of the case to introduce external light of the case into the case. An optical sensor is disposed in the case to detect the light outputted from the light guide. An output signal of the optical sensor is processed by electronic parts on a printed circuit board, and the electronic parts generate an output signal that corresponds to a position of the case.
