Abstract
A pen-like optical input device includes a body. A light source, a light sensing unit and a lens are disposed in the body, a light ray is emitted by the light source to the outside of the body, and a reflected light ray is generated outside the body. The reflected light ray then is received by the light sensing unit after being refracted by the lens, in which the light sensing unit has a light receiving surface, and a normal of the light receiving surface inclines to an optical axis of the lens, thereby forming an angle with the optical axis.
