Abstract
Improved tape guide assemblies for a video tape cassette of the type having two reels between which a length of tape is wound, with each of the reels having only one tape guide flange and the reels being positioned axially parallel with their flanges overlapping and along opposite edges of the tape. One improved tape guide assembly is positioned adjacent each reel to guide at least one side surface and the edge opposite the flange of the tape being wound on or removed from the reel. Each tape guide assembly has an arcuate side guide portion of a smooth low friction polymeric material for guiding the side surface of the tape, and a metal washer at its end opposite the flange of the adjacent reel for guiding the edge of the tape. The tape guide assemblies are attached by screws adapted to be pressed into the side guide portions to facilitate assembly of the cassette, and engage the housing to restrict rotation relative thereto which facilitates removal of the screws to disassemble the cartridge.
