PURPOSE:To easily and accurately adjust a force that a load shaft outputs by providing force adjusting mechanisms which adjust the force that the load shaft outputs to the arms of a reverse surface and flank support lever which constitutes the mechanism respectively. CONSTITUTION:Plural weights which are different in weight value are provided on the arm of the reverse surface and flank support lever, which is a unit support mechanism constituting the reflecting mirror support mechanism, on the opposite side from a support side. An error generated when the weight 7a of the force adjusting mechanism is adjusted in position by 'lever' theory and nuts 10a and 11a are clamped is removed by adjusting the weight 7b which is about 1/50 time as heavy as the weight 7a. An error generated again in the output force of the load shaft owing to the clamping of nuts 10b and 10b is ignored as compared with an error generated after the adjustment of the weight 7a. Consequently, the force that the load shaft outputs can easily be adjusted and the reflecting mirror support mechanism which has high force support accuracy can be realized. |
