Plastic supply tape guide for videocassette.

摘要

When a supply tape guide (14,16) of a VHS or Betamax videocassette (13) is plastic rather than the usual stainless steel, equal or better performance is attained when the plastic is a blend of acetal copolymer and a small proportion of lubricant and anti-static agent. The same plastic may be used for either or both of the supply sleeve and the supply pin, and both can be molded of that plastic as a single piece.
