Abstract
An optical sensing device comprising a shell, at least one light emitting member, at least one optical sensing member and a shading member is disclosed. The shell is formed with a black-body condition space therein, and the light emitting member projects a light beam into the black-body condition space. The optical sensing member is located within the shell and neighboring to the black-body condition space. The shading member is movably arranged within the black-body condition space. At least one end surface of the shading member is contacted with the shell and formed with at least one recess. When the shading member moves to at least one shading region within the black-body condition space, the optical sensing member is shaded by the shading member; and when the shading member moves apart the shading region, the optical sensing member senses the light beam to accordingly send out a sensing signal.
