ABSTRACT:
A tape cassette comprises a pair of reels fixedly holding leading and trailing ends of a tape; and a cassette case containing the pair of reels with a forwardly exposed portion of the tape being extended at the front of the case. An opening is provided inside a forward portion of the case, and left and right side walls are arranged in the cassette case for defining the opening. Two or more tape guides are arranged adjacent to left and right ends of the opening, respectively, for guiding the forwardly exposed portion of the tape. A front lid is pivotably supported by the cassette case for covering the front of the forwardly exposed portion of the tape when closed, and an inner lid is pivotably supported by the front lid for covering the back of the tape when closed. Guiding grooves are arranged in the left and right side walls, respectively, for controlling a pivotal movement of the inner lid. At least one of the tape guides is spaced by a distance L from the opening-side end of its corresponding left or right side wall which has a thickness of T, such that L<T is established.
