PURPOSE:To smoothly insert a driving roller into a driving roller inserting hole even when the roller is touched with any part of a core bar, by constituting a driving roller spring in such a way that the fulcrum of the driving roller can be set in the vicinity of the outer periphery of a yoke. CONSTITUTION:When a driving roller 24a fitted to a driving roller spring 24 is pushed by a core bar 3, the roller 24a inclines with a fitting pin 25 as the fulcrum. Since the driving roller 24a is inclined downward against the advancing direction around the fitting pin 25 even though the roller 24a touches a part of the core bar 3, the roller 24a smoothly moves on the core bar 3 in the direction E and is finally inserted into a driving roller (position controlling pin) inserting hole 5, and then, rotates a floppy disk 2 at the normal position. |
