ール装置。A pair of reel stands, an idler that is rotationally driven by a motor and is selectively crimped to both of the reel stands to selectively drive these reel stands, and is provided corresponding to the upper and both reel stands. a pair of tension levers, a reciprocating optical shutter plate that is selectively interlocked with the tension levers in conjunction with the selective crimping operation of the idler on the reel stands, and the optical shutter plate. From one photoelectric conversion element and a light source provided vertically facing each other,
The tape is selectively driven in the forward and reverse directions by selectively driving the two reel stands, and at the same time, the tape tension on the tape winding side is selectively detected by the tension levers. A tape tension control device configured to control rotation of the motor using a C output signal from the one photoelectric conversion element.
