<p>PURPOSE:To enhance the utilization efficiency of a space and to make a device small in size and light in weight by making at least one of positioning and holding members which respectively position and hold plural guide posts for winding a magnetic tape around a cylinder movable. CONSTITUTION:At least one of the positioning and holding members 912 and 77 for holding the guide posts 910 and 73 at specified positions and in specified posture is set as the movable one, that is, the positioning and holding member 77. Namely, the loading/unloading of the other guide post is smoothly performed by previously retreating the holding member 77 for holding the guide post 73 which forms a specified tape traveling path at the specified position and in the specified posture from the moving path of the other guide post in course of loading/unloading. Thereafter, the holding member 77 is disposed at the specified position to secure the position and the posture of the guide post 73 without being restricted by the moving path of the other guide post. Thus, the utilization efficiency of the space is enhanced and the device is miniaturized.</p> |
