Abstract
A tape cassette, in which a mouth portion opened forward, upward, and downward is provided in a front portion of a cassette shell containing tape reels around which a tape-like magnetic recording medium is wound, and part of the tape-like recording medium is positioned so as to cross the front end of the mouth portion, includes a front lid positioned on the front side of part of the tape-like recording medium positioned so as to cross the front end of the mouth portion; a slider movable forward and rearward, the slider being provided on the cassette shell; and a back lid positioned on the rear side of part of the tape-like recording medium positioned so as to cross the front end of the mouth portion, the back lid being separated rearward from the tape-like recording medium along with rearward movement of the slider. The tape cassette is characterized in that the back lid is supported on the slider, and each of the slider and the back lid is made from a good conductor, for example, stainless steel. With this configuration, it is possible to prevent occurrence of tape jamming liable to occur at the time of cassette loading or tape loading performed by insertion of a tape cassette having a front lid and a back lid in a cassette holder.
