Claims

[Scope of utility model registration request]

The inside of the index of unit length that differs at a constant ratio is made to have a different amount of light from the surrounding of the index, and the lengths of multiple indexes of each unit length are matched and arranged in parallel, and each index row of unit length is one index. The main scale is a set of 1-0 indicators, which are defined as numerical values from 0 to 9, and are continuous in the length direction for each unit length. The auxiliary scales, which differ in light intensity from the surroundings in the same way as the indexes, are extended alternately from the overlapping part at right angles to the length direction, and are positioned at each boundary of each index, and are arranged for each index row of each unit length. A plurality of waveguides, such as optical fibers, are arranged in a line perpendicular to the measurement direction. In addition to establishing
A plurality of vernier waveguides are arranged in the length direction in the overlapping part of the auxiliary scale of the index row of the minimum unit length, and when the waveguide row is located at the boundary of the index, the signal from each auxiliary scale is A measuring device configured to have a reader equipped with a circuit that cuts lower numerical values in the same index column and display the read value on a display.
