Claims

[Scope of utility model registration request]

(1) A fixed scale having a circular inner periphery and having scales attached thereto; at least two types of scales that rotate along the circular inner periphery of the fixed scale and corresponding to the scales of the fixed scale. an annular rotary scale with a mark attached thereto; a needle-like cursor rotatably provided around the center of the rotary scale; meshing with a rotation mechanism of the cursor, and an edge thereof protruding from the outer periphery of the fixed scale; an enlargement/reduction converter comprising: a distance measuring roller; and a mechanism for rotating the rotary scale together with the rotation of the cursor only when the cursor is rotated in one direction.

(2) The converter according to claim 1, in which the rotation mechanism of the rotary scale includes a stopper pin that protrudes from the top surface of the rotary scale and comes into contact with the side surface of the cursor.
