ABSTRACT:
A tape cassette which is convenient for minimization is provided. A cassette case is formed from an upper half and a lower half. A back lid includes a front lid, a back lid and a top lid, and covers over a portion of a magnetic tape positioned outside the cassette case. A lid locking member is mounted on the cassette case for engaging with an arresting recessed portion of the front lid to lock the lid member at a closed position. A torsion spring for biasing the lid member toward the closed position is resiliently contacted at an arm thereof with a spring anchoring portion of the lid locking member to exert a pivoting force to pivot the lid locking member to its locking position. A stopper portion is provided on the lower half such that an abutting portion of the lid locking member may be abutted therewith to prevent excessive pivotal motion of the lid locking member toward the locking position.
