Claims

[Claims for Utility Model Registration] (1) The cassette case 3 has a slider 1 attached to the cassette case 3 so as to be able to freely open and close a space for inserting guides by sliding over the bottom and side surfaces of the cassette case. A through hole 2 is bored in the bottom of the slider 1, and the slider 1 is inserted into the through hole 2 in the closed and open states at a position corresponding to the through hole 2 in the bottom of the cassette case 3 to lock it. A magnetic tape cassette having an elastic locking piece 5 having a head 4, characterized in that the elastic locking piece 5 is configured to be elastically deformed so that the cross-sectional area of the elastic locking piece 5 gradually decreases toward the head 4. . (2) The elastic lock piece 5 is attached to the cassette case 3.
2. A magnetic tape cassette according to claim 1, which is a magnetic tape cassette that is integrally connected to the magnetic tape cassette and has a thickness that becomes thinner toward the head portion 4 from a base portion serving as a fulcrum. (3) The utility model registration claim 1, wherein the elastic lock piece 5 is integrally connected to the cassette case 3 and tapers in the width direction from a base serving as a fulcrum toward the head 4. magnetic tape cassette. (4) The elastic lock piece 5 is gradually reduced so that the cross-sectional area of the tip of the head 4 is in the range of 80 to 20% when the cross-sectional area of the base serving as the fulcrum is 100%. A magnetic tape cassette according to claim 2 or 3 of the utility model registration claim.
