ABSTRACT:
In a short-time recording tape cassette having a mouth section for receiving a head drum, a pair of tape reels can be moved to a rear portion in a cassette case of the tape cassette upon loading of the tape cassette into a recording/reproducing device, thereby eliminating a dead space in the cassette case and further expanding the mouth section. Accordingly, a more compact construction of the recording/reproducing device can be realized. Moreover, a spring for biasing the tape reels is configured in a substantially S-shaped cross section, so as to make a biasing force of the spring against the tape reels before the movement of the tape reels substantially equal to that after the movement of the tape reels.
