PURPOSE:To improve the accuracy of alignment, by forming a guide initial slope aligning and guiding a disc into an obtuse angle and a guide end slope into a sharp angle, linking the guide slopes of two elements in a curved surface so as to eliminate folded flaws of the disc. CONSTITUTION:A collet aligning and guiding the flexible disc is provided with the guide iitial slope 17 and the guide end slope 17-1. Then, the guide initial slope 17 is formed at an obtuse angle and the guide end slope 17-1 is formed at a sharp angle, and the guide slopes of the two elements are linked in a curved surface. Thus, no folded flaw of the disc is produced, the accuracy of alignment is improved and the thin thickness is attained easily. |
