<p>PURPOSE:To improve the accuracy of mounting and setting by disposing a leaf spring to face a backing plate apart at a required spacing therefrom and pressing the mounting datum plane of a matching telescope always under the uniform pressure to the backing plate by the force of the leaf spring. CONSTITUTION:The leaf spring 18 is mounted to a block 20 by means of a screw 19. The block 20 is so shaped that the leaf spring faces the backing plate 15 and that the spring force can be acted at >=2 points thereto by means of bolts 21 to prevent the uneven contact of the side mounting datum plane of the matching telescope with the backing plate. An operator in this case can press the side datum plane to the backing plate with always the uniform force generated by the force of the leaf spring. Generation of a difference in the mounting and setting accuracy of the matching telescope by a difference in the operator, etc., is, therefore, eliminated and the accuracy of mounting is improved.</p> |
