Claims

[Scope of utility model registration request]

In a fine rotation mechanism for a pedestal 9 that rotates around a point 8, the pedestal 9 has a structure in which a spring is arranged on one surface to press the pedestal in the direction of the center line 17 of the pedestal, and a sliding surface is provided on the opposite surface. ,
The above-mentioned pedestal has two inclined surfaces with different angles on one surface, each in contact with the fixing pins 12a and 12b, and the opposite surface is a dynamic surface corresponding to the dynamic surface of the pedestal. The spring 14 is disposed on one surface in the direction along the center line 17, and has an end that is pressed from the opposite side via the direction lock knob 11 along the center line, and the two inclined surfaces are aligned with the center line. If the angles formed are θ and θ2, respectively, tanθ
It has an angle plate formed to satisfy 1:tanθ2 =A-8:-8 (A and B are the intersection points of the perpendicular line drawn from the contact point of the angle plate and the positioning pins 12a and 12b to the center line 17). , a fine rotation mechanism characterized in that by turning the knob, the angle plate is moved along an inclined surface, thereby applying a rotational force to the pedestal 9, and slightly rotating the pedestal about a point 8;
