摘要： A flexible disc cassette is provided with a shutter which is capable of opening/closing a head access hole and a pad insertion hole respectively formed in upper and lower halves thereof. A V-shaped torsion spring is used as the spring for biasing the shutter in the closed position. The lengths of the linear arm portions integrally formed with both sides of the coiled portion of the spring are approximately the same. Both tips of the arm portions are bent at approximately 90.degree. so as to form the L-shaped hooks which has the same length and which extend in the opposite directions along the height of the coiled portion. The L-shaped hooks are stopped by the shutter and the cassette case.
