ABSTRACT:
Elastic cushion sheets are interposed between the side faces of the tape convolutions and respective halves of the casing of a magnetic tape magazine. The cushion sheets are held on the inner face of the halves by the engagement between a pair of holes provided through each of the cushion sheets and a pair of projections formed integrally on each of the halves. The outer diameter of the projections is slightly smaller than the inner diameter of the holes. The projections are initially formed to extend vertically from each half of the casing, and at least one of them on each half of the casing is made to incline with respect to the vertical after the cushion sheet is put thereon with the holes thereof engaged with the projections. The free end of each inclined projection is moved laterally beyond the edge of the associated hole. The cushion sheet is prevented from falling from the half of the casing even if the half is inverted with the inner face thereof directed downwardly as in assembling the tape magazine, whereby assembly is facilitated.
