Abstract: A reel drive disc device has a sliding friction clutch for transmitting output power, at constant rotational speed and with a desired torque, to a reel-supporting disc which is rotated at a speed that varies in accordance with the diameter of the tape roll wound thereon. This sliding friction clutch operates responsive to a pressing together of a felt friction member and a member made of a highly wear-resistant resin such as a polyethylene terephthalate resin. Its power transmitting torque is maintained substantially constant over a long period.
