The pointer includes an upper surface on which a fluorescent part having fluorescent brightener therein is formed, and the area of the fluorescent part of the pointer is smaller than that of the upper surface of the pointer. Each of the indicia has a contour defined by a normal ink having a different color from the ground color of the scale plate and a fluorescent part having fluorescent brightener therein formed in the contour of each indicia.

Abstract: A wire cutting electric discharge machine, in which a wire 27 which has been used a is interposedly supported between opposed top and bottom endless belts 35 and discharged from the machine. The force between the belts 35 with which the wire is interposedly supported can be increased, and the wire 27 can be discharged irrespective of any wear on the belts 35. In addition, in order to extend the life of the belts, during the interval in which the wire is being interposedly supported by the belts, a twist is imparted to the belts and a pair of wire discharge rollers which stretches the wire provided at the rear side of the belts.
