Abstract: A tape cassette comprises a supply and a take-up reel on which tape is wound, a cassette casing for rotatably enclosing the reels therein, a plurality of tape guide pins, each being press-fitted through the inner wall of the casing, for defining a tape path for the tape travelling between the pair of reels. The press-fit section of each guide pin is formed in a predetermined taper in such a manner as to gradually decrease its outer diameter towards its end. The straight press-fit section of the guide pin is formed in such a manner as to include a predetermined geometry of chamfered circumference at its end. In a tape guide pin used in conjunction with a tape guide roller, grease having a predetermined viscosity coefficient is disposed between the associated pin and roller. An electrical insulating cover is provided for surrounding the exposed underside of the electrically conductive lower half of the casing.

Abstract: A flexible disc cassette is provided with a shutter which is capable of opning/closing a head access hole and a pad insertion hole respectively formed in upper and lower halves thereof. A V-shaped torsion spring is used as the spring for biasing the shutter in the closed position. The lengths of the linear arm portions integrally formed with both sides of the coiled portion of the spring are approximately the same. Both tips of the arm portions are bent at approximately 90.degree. so as to form the L-shaped hooks which has the same length and which extend in the opposite directions along the height of the coiled portion. The L-shaped hooks are stopped by the shutter and the cassette case.

Abstract: PCT No. PCT/JP94/00898 Sec. 371 Date May 11, 1995 Sec. 102(e) Date May 11, 1995 PCT Filed Jun. 3, 1994 PCT Pub. No. WO94/29194 PCT Pub. Date Dec. 22, 1994A tape cassette receiving housing comprises a housing proper portion and a lid portion which is fixed to the housing proper portion through a hinge portion so as to enable to be opened or closed. Shaft portions are formed so as to penetrate into reel driving holes of a supply reel and a take-up reel of a tape cassette received in the housing proper portion. Elastic bodies are attached to outer peripheries of the shaft portions, and the elastic bodies are brought into contact with inner peripheral surfaces of reel driving holes. According to the above construction, a tape cassette is fixed in the tape cassette receiving housing so as not to incline the tape cassette and not to rotate the supply reel and the take-up reel.

Abstract: A tape cassette receiving casing (1) comprises a casing body (2) and a cover (4) openably mounted to the casing body (2) by a hinge portion (3). Shafts (5, 6) are provided to be inserted into reel drive holes (114, 115) of a supply reel and a take-up reel on a tape cassette (111) which is received in the casing body. Elastic bodies (7) are mounted on the outer peripheries of the shafts to bring them into contact with the inner peripheral surfaces of the reel drive holes. With the arrangement, a tape cassette is secured in the tape cassette receiving casing so that it will not be inclined and the supply reel and take-up reel will not rotate despite shocks at the time of falling and vibrations during transportation.
