Abstract
A tape cassette incorporates an anti-static member that dissipates static electricity on the tape as it runs. The anti-static member comprises an electrically conductive strip that flexibly engages the edges of the coils of tape wound on reels inside the cassette housing. A tab integral with the strip extends into a locating hole of the cassette housing for engagement with a conductive locating pin on the apparatus using the cassette when the cassette is installed. The tab provides a grounding means that completes the connection of the tape to ground and prevents the build-up of static electricity on the tape as it rubs itself and the cassette guiding elements while it is running.
