Summary: | A magnetic tape cassette includes a leaf spring and magnetic tape reels in which the depression force of the leaf spring is varied such that, in assembling the cassette, the leaf spring provides a relatively weak depression force thereby to facilitate cassette assembly, and when the cassette is in use, the leaf spring provides a relatively strong depression force to sufficiently depress the magnetic tape reels. The magnetic tape cassette also includes a pair of protrusions formed on the inner surface of the top wall of an upper half casing which can abut the arms of a leaf spring secured to the upper half casing, so that, in assembling the cassette, the leaf spring is bent until it is brought into contact with the protrusions. When the cassette is in use, the leaf spring is further bent with the protrusions serving as fulcra, thereby to increase its force of depression. |
