Since the tape is already running at a constant speed, the running control circuit (37 Fi70S4#) is not connected, but the ND gate (4) already has a signal instructing the tape to run at a constant speed. Since the reel rotation period detection circuit (5) is in an operating state, a signal is output from the ND gate (4).The reel rotation period detection circuit (5) is connected to the supply side reel. A cycle of one revolution of the supply reel (6) is generated from the pulse generated by the rotation detector (7) that detects the rotation of the supply reel (6), and a signal corresponding to the tape thickness from the tape thickness signal generation circuit (8) is generated. , along with a signal corresponding to the hub diameter from the hub diameter signal generation circuit (9).

示さｎる。When the remaining amount display switch (1) is pressed, the signal is latched by the latch circuit (2), f'L is output to the MD gate (4), and the running control circuit (4), and the signal is output to the running control circuit (4). The control circuit (3) switches the tape running mode to a constant speed mode, with no special indication. A signal to warn the running is output from the running control circuit (3), and a signal to operate the reel rotation period detection circuit (5) is output from the nD gate (
4) Output. Thereafter, the same signal processing as when the tape is running at a constant speed of II/f is performed, and the remaining amount of the tape at the position where the remaining amount display switch +13 is pressed is displayed.
