。[Claims for Utility Model Registration] Consisting of a reel stand rotation speed measuring mechanism 2 and a remaining tape amount calculating section 3, the reel stand rotation speed measuring mechanism 2 has a driving reel stand 4 and a driven reel stand on the mounting surface 12 of the tape cassette. 5, a driving mechanism 40 for rotationally driving the reel stand in the tape winding direction is connected to the driving reel stand 4, and a driving mechanism 40 that rotates the reel stand in the tape winding direction is connected to the driven reel stand 5. A mechanical counter 7 that counts with the following significant digits is connected, and the remaining tape amount calculation section 3 is connected to an input section 30 for inputting the rotational speed of both reel stands 4 and 5, respectively, and A tape remaining amount measuring device comprising a calculation section that calculates the remaining amount of tape based on the ratio of rotational speeds of , and an output section 32 that displays the calculation result of the calculation section. The calculation part is calculated using the formula T=πvt× However, T: Remaining amount of tape on the supply reel (time) v: Tape speed t: Tape thickness R 0 : Tape winding radius when winding is completed R: Reel hub radius n 1 : The rotation speed of the reel stand where the take-up reel fits. n 2 : Rotation speed of the reel stand into which the supply side reel is fitted. The tape remaining amount measuring device according to claim 1, which is capable of calculating the remaining tape amount T based on the following.
