ABSTRACT:
A tape cassette is so arranged that an endless tape, stored in a tape accumulating portion in a cassette body, to which a front lid is pivotally movably secured, to thereby assume an open position and a closed position with respect to a front opening in the cassette, and pulled out of the cassette body, is again drawn into the cassette body, by means of a tape drawing reel mounted in a position displaced to one side from the center of the cassette body. A pair of elastic members are disposed in an elastically contracting relation to each other, with the free ends thereof facing a tape discharge gate within the cassette body, so that the endless tape can pass through the pair of elastic members. The tape cassette further includes a rotatably mounted, reverse rotation check member; and a flexible member attached at one end or in the intermediate portion thereof to the cassette body, with the other end maintained in pressure-contact with an elastic member surrounding the flank portion of the tape drawing reel. The flexible member is slidably connected in a portion between the fixed portion and the aforesaid other end to the reverse rotation check member. When the tape drawing reel is rotated in a reverse direction, the aforesaid other end portion of the flexible member is strongly pressed against the elastic member while being deformed, thereby pressing the reverse rotation check member against the tape drawing reel thereby impeding reverse rotation thereof.
