The present invention has an object to provide an optical reader which is compatible with every environment irrespective of installation and usage environments, thereby enabling uniform manufacturing, satisfactory reading reliance, and operative safety and user-friendliness. The optical unit is mounted on the stage, and there is provided an inclination apparatus which inclines the stage at a desired angle. Thereby, without changing a preset optimal scanning pattern, only its emitting direction becomes changeable freely.
