PURPOSE:To obtain a running amount detection label possible for sticking, by displaying a scale with a line representing the length of a tape (running time) having a length from a position corresponding to the circumference of a reel winding core to the vicinity of the outer circumference of the reel, and different intervals depending on the tape winding diameter wound on the winding core on the surface. CONSTITUTION:Two kinds of scale lines are prepared with different position of reference scale lines 4', 4'' being a reference to the said scale line 4 for the surface of the reel 2 (payoff side, hereinafter side A) and the back side (winding side, hereinafter side B). Fig. A is for the side A and Fig. B is for the side B. Both the side A and B have the reference scale lines 4', 4'' being coincident with the circumference of the winding core 5 of the reel 2 and the length of tape (time) is scaled by taking the reference scales 4', 4'' as references. Spaces 4b, 4b (15min for 3hr tape) being excessive to the nominal length of the tape are provided for the winding core 5 for the side A and for the outer circumference for the side B. |
