2. Description of the Related Art Conventionally, there has been a stationary band sawing machine equipped with a light. However, a portable band sawing machine or a portable band sawing machine is mounted on a stand or the like to be fixed to a vertical shape and cut on a guide table. None of the so-called contour cutting band saws for cutting materials was equipped with a light. For this reason, in the cutting work in a dark work place, work was performed by illuminating the vicinity of the cutting location with another light, or cutting was performed in a dark state where the material to be cut could not be seen clearly.

In the conventional portable band saw machine, it is necessary to prepare another light in order to make the work area brighter when the work place is dark, and it is troublesome to secure the power supply and turn the cord. Was. In general, when performing on-site cutting work, it is common to bring a band sawing machine to the cutting point of the material to be cut, and each time the light is illuminated with the light and the time required to move the light, There is a problem that a shadow of a hand or the like is formed on the material, a black line indicating the cutting position is not clearly seen, and it may be difficult to align the cutting position. The same applies to the so-called contour cutting in which a portable band saw is fixed to a vertical shape by a stand or the like and the material to be cut is cut on a guide table.
