管内面写真判定用ゲIt is a gauge for judging a tube inner surface photograph taken of the entire circumference of the tube inner surface, and it divides at least a 90 degree range of 10 degrees within a circle of the required diameter marked on a transparent film, and divides the rest as appropriate. At the same time, the game for determining the inner surface of a tube is characterized in that the range divided by 10 degrees is further divided sequentially from 1 degree to 9 degrees.
