Zusammenfassung:	PURPOSE:To wind up a polishing tape after its work smoothly and surely by coupling the drive shaft of a takeup motor with the takeup shaft of a takeup reel through a friction transmitting means with possibility of slippage. CONSTITUTION:A takeup reel 18 is rotated by a takeup motor 15 through a belt 24 set over a rotary hub 23 of said takeup reel 18 and a rotary hub 22 of a drive shaft 15a. Therefore, increase in the load on the takeup reel side generates slippage of the belt 24 wound round a takeup shaft 18b of the takeup reel 18. Consequently the revolving speed of the takeup reel 18 reduces with increasing amount of tape 14 wound up, and this amount of wound-up tape becomes constant, corresponding to the amount of the polishing tape 14 being fed by said takeup motor 15. Accordingly proper and tight winding-up is provided to ensure that the tape 14 does not entangle with other members.
