機構。 A reel drive shaft that rotationally drives the tape reel is provided with a disk portion that rotates integrally with the reel drive shaft, and a drive wheel that is rotationally driven by a motor about the rotation center of the reel drive shaft is provided below the disk portion. At the same time, one of the drive wheel and the disc part is provided with a sun gear in the center thereof, and the other is provided with an outer gear facing away from the outer periphery of the sun gear, and the drive wheel and the disc part are provided with a sun gear in the center thereof. A rotary body that rotates about the rotation center of the reel drive shaft is disposed between the rotary body and the rotary body rotatably supports a planetary gear that meshes with the sun gear and the outer ring gear, and A reel drive mechanism characterized in that a friction brake member that provides resistance to the rotation of the rotary body is provided on the outside so as to be movable toward and away from the outer peripheral surface of the rotary body.
