ABSTRACT:
In a magnetic tape cassette of the type having an upper shell, a lower shell and a pivotable guard panel assembled together to hold therein a magnetic tape wound on a pair of tape reels, a mouth is provided in said lower shell along a front side of said tape cassette for receiving therein a loading pole for withdrawing a segment of the magnetic tape from said tape cassette, and a protective plate is pivotably mounted on said lower shell behind said guard panel and is cooperative with said guard panel to enclose the segment of the magnetic tape for protecting the latter against damage. The protective plate is pivotally movable within the mouth independently from the guard panel and hence it does not increase a maximum height of the tape cassette when the guard panel is disposed in the open position. The protective plate is lockingly engageable with the guard panel to hold the latter in the closed position against displacement. A plurality of independently movable plate members compose the protective plate.
