ABSTRACT:
A magnetic tape cassette is provided with shielding means for the guide posts thereof, including a clip member of electrically-conducting material, for preventing build-up of static electrical charges and resultant clinging of the tape to the guide posts, when it is desired to pull the tape from the guide posts by vacuum pressure-differential apparatus, as for threading into a tape transport.
