Abstract
A magnetic tape cassette accommodating case has a cover member having a pocket for receiving one end portion of a magnetic tape cassette and a casing member having rotation stopper projections. At least (a) peripheral portions of the cover member and the casing member, which edge portions confront at least the thickened portion of the magnetic tape cassette, and (b) side wall portions of the cover member and the casing member, the side wall portions including the pivotably assembled portions, are molded with a resin, which is more slidable than the other portions of the cover member and the casing member. The other portions are molded with such a transparent resin as to allow the case to be seen through. A method for manufacturing such a magnetic tape cassette accommodating cage utilizes a first slide core slidable in a direction of inserting a cassette, and a second slide core movable substantially orthogonal to the direction of moving the first slide core.
