Accordingly, the reflecting mirroris capable of rotating with respect to the caseand only the reflecting mirroris capable of adjusting the set up angle α made with the case. When the set up angle is changed, the reflecting angle of the projected ray on the reflecting mirroris also changed. Therefore, the launching angle of the projected raywith respect to the casecan be adjusted.
