Abstract

This invention relates to an optical indicator, particularly to one applied to a rotary sawing machine and externally projecting a light mark parallel to the sawing disc on a work piece as a reference for cutting. The opticl indicator is located on the shaft at the same side as the sawing disc and combined with a multi-faceted element for reflection or refraction. When the shaft is driven to rotate, the multi-faceted element reflects a light beam emitted from a laser unit arranged in the exterior into a linear light mark parallel and adjacent to the sawing disc on the work piece as a cutting reference.
