MAGNETIC TAPE WIND-UP DEVICE

摘要

A MAGNETIC TAPE WIND-UP DEVICE DESIGNED TO WIND UP A MAGNETIC TAPE (20), WHICH IS FED AT A CONSTANT SPEED BY A CAPSTAN (24) AND A PINCH ROLLER (27), AROUND A REEL (15) IS PROVIDED WITH A SLIP MECHANISM HAVING A DRIVE SLIP GEAR (1) DRIVEN BY A MOTOR (6) TO ROTATE AND A DRIVEN SLIP GEAR (2) WHICH IS IN FRICTIONAL ENGAGEMENT WITH AND IS DRIVEN TO ROTATE BY THE DRIVE SLIP GEAR (1) WHILE SLIPPING THEREWITH, THEREBY TO DRIVE THE REEL (15) TO ROTATE. THIS SLIP MECHANISM IS CONFIGURED TO BE CAPABLE OF REDUCING THE MEAN SLIP TORQUE BY PERIODICALLY CHANGING SLIP TORQUE, THEREBY MAKING IT POSSIBLE TO WIND UP A TAPE CASSETTE (19) HAVING A HIGH ROTATIONAL LOAD WITHOUT TROUBLE.
