Abstract

PURPOSE: To facilitate handling, by providing a scale, which indicates the height of the prism at the tip of the pole, on the surface of the inside cylindrical material which is fitted and inserted into the outside cylindrical material of the pole, which is painted with red and white alternately, so that the inside cylindrical material can be expanded and contracted freely.
CONSTITUTION: Target pole 1 is provided with prism 19 in the head part and is painted with colors such as red alternately on the surface of outside cylinder 4 to make rough calculation of the height possible. A scale for full height from ferrule part 3 to prism 19 is provided to inside cylinder 5, and height H+h can be read with lower end K of the outside cylinder as the cursor line. Slide disc 19 is provided in upper end part 6 of the inside cylinder which is fitted and inserted into outside cylinder 4 so that the inside cylinder can be expanded and contracted freely; and when inside cylinder 5 is twisted, rotary disc 13 which is so fitted to slide disc 19 that off-center rotation is possible by screw 18 is rotated, and outward extending leg pieces 15 fixed to rotary disc 13 are press-contacted to the outside cylinder inside wall to prevent drop dependent upon the weight of the outside cylinder itselt. Consequently, handling and production are easy.
