<p>At least one pair of regulating blocks are provided on a base table so as to move on a major face of the base table in parallel therewith. Each of said pair of regulating blocks has a holding face with a regulating face so as to position a member to be adjusted in a desired angle. The member to be adjusted is held by the holding faces of the respective regulating blocks and, as a result, the member is positioned in the required angle following the regulating faces of the respective holding faces. With the so constructed device of the present invention, the member to be adjusted can be easily positioned with respect to its angle simply by holding the member by at least one regulating blocks.</p> |
