Tape winding mechanism
Because the tape is pulled while transferring it to the paper, the tape reel rotates. Then, the rotation force turns the slack reel through the gear, and it is possible to wind up the transcribed tape which becomes slack.
The principle is simple, but the hardest part is that the tape reel is slow when the tape is large, the reel slack reel is rotated quickly, the tape is reduced, the tape reel is quickly reversed, and the reel is slack reel Is to rotate slowly. There is a mechanism to transmit the rotation force of the tape reel while slipping using O-ring etc.
