<p>PURPOSE:To improve the operating accuracy of a pinch roller by using a pinch roller arm so as to drive a pinch roller arm drive member engaging pinch roller blocks via long holes. CONSTITUTION:The pinch roller arm drive member 6 and the pinch roller arm 8 are connected freely slidably and turnably via a long hole 8a. Thus, considerable flexibility is given to the operation of both the members 6, 8, resulting that the operating ranges of both the members 6, 8 are overlapped and the effective utilization of the space is attained and the entire device is miniaturized. Since the pinch roller arm 8 and the pinch roller block 10 are connected via the pinch roller link 9, then considerable flexibility is given to the operation of the pinch roller block 10 and a free S-shaped moving path is set by utilizing the space effectively and the distance between the pinch roller guide slot 13 and the loading guide slot 19 is narrowed to reduce the space.</p> |
