摘要： A recording tape cartridge includes a reel, a case where the reel is accommodated, an engagement gear that is provided in the reel, and a brake gear which is provided in the case side brake member and in which a mesh state with the engagement gear or a mesh release state with the engagement gear is switched by relative displacement of an axis line direction of the brake member with respect to the reel. In a piece taper tooth of the engagement gear, a mesh surface that is oriented in a winding rotation direction is approximately parallel to a reel axis line direction and an opposite mesh surface is inclined with respect to the reel axis line. A piece taper tooth of the brake gear is a taper tooth that is opposite to the piece taper tooth of the engagement gear.

摘要： A method of manufacturing a roller includes: forming a hollow cylindrical body that includes a fully solidified outer peripheral surface and a semi-solidified interior, with an inner peripheral surface swelling inwardly; and pressing the swollen portion of the inner peripheral surface outwardly by pulling an insert die from the semi-solidified cylindrical body, to thereby allow the outer periphery of the cylindrical body to swell outwardly in a barrel-like manner. A primary molded product including a through hole along a central axis is thereby formed, and a secondary resin is injected into the through hole of the primary molded product.

摘要： At both sides of an opening (14) of a cassette case (10a), there are formed tape guides (18) having guide faces (18a), and a magnetic tape (T) is stretched between the guide faces (18a). On back faces (18b) of the guide faces (18a) of the tape guides (18), are formed cam grooves (26) for guiding an open/close lid (320) which covers the stretched magnetic tape (T). In lower parts of the back faces (18b) and backward of the cam grooves (26), there are formed projections (28) provided with position detecting holes (28a). Molding sink preventive recesses are formed only at positions on the back faces (18b) forward of the cam grooves (26) and above the projections (28).

摘要： The hook 2a of a lid lock 2 is urged by a spring 48 so that an outer lid 41 integral with the lid lock pawl 45 is locked closed. At that time, the hook 2a is abutted against the side surface of a lid lock pawl 45 which formed in the side board of an outer lid 41. In the case where an impact is applied to the magnetic tape cassette, the impact force is absorbed by the side surface of the lid lock pawl 45 and the lid lock 2. At that time, an arcuate surface 2b confronting with the end portion of the lid lockpawl 45 prevents the end portion 45a of the lid lock pawl 45 from being collapsed or rolled up. Accordingly, the occurrence of troubles such as the deterioration in function of the lock mechanism, and the biting of the magnetic tape is prevented.

摘要： A cassette accommodating case in which a tape cassette can be inserted in either a forward or backward orientation, and for preventing slackening of a magnetic tape, and to secure the tape cassette to eliminate play. Positioning projections having inclined surfaces are provided on each side of a casing section. When the casing section and a cover section are closed, the inclined surfaces abut against the ends of side projections on side surfaces of the tape cassette to push the tape cassette when the casing and cover sections are closed. A rotation-preventing projection of an accommodating case protrudes into a common area of the hubs when a cassette is loaded in the forward and backward orientations, and the projection includes two plate-like portions of different heights, disposed in parallel, and with a predetermined interval therebetween. A distal end of the long plate-like portion has a guiding inclined surface for correcting the positional offset of the hub by contacting its inner peripheral surface. The hub is retained by the two plate-like portions. Backward-pressing surfaces are provided in opposing corner portions of the case to secure the cassette tape within the case.

摘要： 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 case 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.
