ABSTRACT:
A tape cassette for use in a magnetic recording and reproducing apparatus, such as a video tape recorder (VTR), includes a cassette casing having a front wall provided with tape outlets in its opposite side portions, a mouth area between the tape outlets and a recess in one of the tape outlets. A magnetic tape is wound around tape reels in the cassette casing and a portion of the tape between the reels is led out of the tape outlets so as to extend across the mouth area. Front and inner lids are mounted on the cassette casing for angular movements between a closed position in which the portion of the magnetic tape extending across the mouth area is sandwiched between the front and inner lids which thereby protect that portion of the magnetic tape. Further, when the front and inner lids are in the closed position the recess in one of the tape outlets is covered by a tongue portion extending from the front lid. Upon inserting the tape cassette into the VTR, the front lid and the tongue portion thereon contact a lid opening member of the VTR, whereupon the front and inner lids are opened, thereby exposing the portion of the magnetic tape extending across the mouth area and the tape outlets.
