Description

  The present invention relates to an electric circular saw processing apparatus that can use an electric circular saw to cut a work material accurately, safely, and simply.

Conventionally, an electric circular saw has been widely used for cutting a work material, and is generally used with a black line in the work material.
For example, a circular saw is moved along the black line of the processed material (see Patent Document 1) or a circular saw is used with a ruler applied to the processed portion (see Patent Document 2).
However, considerable skill is required to use the electric circular saw along the black line of the processing material, and troubles during processing are not exhausted.
That is, material due to bending, wasted time, and accidents caused by circular saw blades.
In addition, when processing a processed material with an electric circular saw, if importance is attached to the surface property of the processed material, the processed material is used on the back surface to prevent scratches and dirt.
For this reason, when working material is processed from the back side, a black line is not visible, so there are many erroneous operations.
