摘要：
A magnetic tape cassette in which a locking member is slidably biased away from a front opening of the cassette to lock the tape hubs. The locking member has a pair of side arms interlocked with a front panel of the cassette so that, when the panel is rotated open, the locking member disengages from the hubs.
