Abstract
An optical sensing device, which includes a shell, at least one light emitting member, a shading member, at least one anti-static member and at least one optical sensing member, is disclosed. The shell is formed with a black-body condition space therein, and the black-body condition space has a light emitting chamber, a shading chamber and at least one optical sensing chamber. The light emitting member projects a light beam into the light emitting chamber. The shading member is movably restrained within the shading chamber, and generates a static electricity when moving therein. The anti-static member is arranged in the shading chamber to ground the static electricity. The optical sensing member is arranged in the optical sensing chamber, and senses the light beam to accordingly send out a sensing signal.
