<p>PURPOSE:To obtain a pinch roller drive mechanism capable of adjusting a position of a pinch roller by a position adjusting means in the first shaft, winding a pinch roller plate on a winding transmission member through this position adjusting means so as to adjust the position in a length direction of the transmission member and providing the pinch roller in the second shaft. CONSTITUTION:A pinch roller drive mechanism consists of a rotating drive means 10 of a drive wheel, the first pulley 18 as the drive wheel disposed on a shaft 16, a string 20 as a winding transmission member wound between the first and the second pulleys 18, 19, the first and the second pulleys 23, 24 disposed with a space left therebetween and a pinch roller plate 22 attached to the string 20. Further, it consists of a position adjusting means 25 disposed on the first shaft 23 and adjusting the position of the pinch roller plate 22 in the direction of the length of the string 20, a preceding roller 33, a pinch roller 34, a pinch cam plate 37 as an operating plate consisting a pinch roller pressing means and a pinch push plate 42. Thereby, the position can be adjusted so as to correctly stop the pinch roller at a prescribed position when being pulled out at a prescribed position in an aperture part of a tape pack.</p> |
