The invention provides a reel support drive mechanism which has a frictional power transmission mechanism 2 disposed in a power transmission path extending from a motor toward two reel supports 7, 71. The transmission mechanism 2 comprises a felt plate 23 interposed between a pulley 21 and PLAY and REV disks 32, 26 which are rotatable relative to and coaxially with the pulley. The PLAY disk 32 is slidable in contact with an outer peripheral region of the felt plate 23, and the REV disk 26 is slidable in contact with an inner peripheral region of the felt plate 23. A one-way clutch spring 27 is provided between the PLAY disk 32 and the REV disk 26. Power is output from the PLAY disk 32.
