Abstract: A tape cassette includes a pair of cassette halves and a pair of hubs enclosed between the cassette halves, and about which a recording medium, or tape can be wound. Each cassette half includes a first moulded body and a second moulded body overlying it. The first moulded body has a first principal surface and a first upstanding wall which is perpendicular to the principal surface and forms an integral part thereof and a part of a peripheral surface of the half. The second moulded body has a second principal surface which is generally rectangular and overlies the first principal surface, and a second upstanding wall connected to the first upstanding wall to form the peripheral surface of the half therewith, forming an integral part of the second principal surface and surrounding it. The first and second upstanding walls are connected by a junction having a thickness increasing gradually across the thickness of the half.

Abstract: There is disclosed a tape cassette in which fixed guide pins (9,10) are disposed at the position in which a wrapping angle at which a magnetic tape is wound around the fixed guide pins (9,10) when the magnetic tape is transported is reduced (i.e., position at which the tape wrapping angle does not exceed 40 DEG ). In this tape cassette, a frictional force generated between the fixed guide pins (9,10) and the magnetic tape (3) when the magnetic tape (3) is transported is reduced as compared with a conventional tape cassette, whereby a load on a motor for transporting the magnetic tape (3) is reduced, resulting in a life of a battery being extended.

Abstract: Se presenta un cassette de cinta en el que los pernos guía fijos (9), (10) están ubicados en la posicion en al que se reduce el ángulo de enrollamiento (es decir, la posicion en al que el ángulo de enrollamiento del cinta no exceda de 40 degree ). Con el que la cinta magnética se embobina alrededor de los pernos guía fijos (9) (10) cuando la cinta magnética se transporta. En este cassette de cinta, la fuerza de friccion generada entre los pernos guía fijos (9) (10) y la cinta magnética (3) cuando la cinta magnética (3) se transporta, se reduce en comparacion con un cassette de cinta convencional, con lo que se reduce la carga en el motor para el transporte de la cinta magnética (3), lo que da por resultado que se prolongue la vida de la batería.

Abstract: In order to produce a cassette, such as tape cassette, disc cassette or the like, the following steps are taken. First, fixed and movable dies (22,23) are prepared which are unitable to define therewithin a shaped cavity. The movable die (22) has at its inner surface a retaining ridge (21) which includes a first portion (21a) immediately projected from the inner surface and a second portion (21b) immediately projected from the first portion (21a). The second portion (21b) has side walls at lease one of which has a laterally extending projection at the position remote from the first portion. Second, the fixed and movable dies are coupled to define the shaped cavity therewithin. Third, a plastic material is injected into the shaped cavity in such a manner that the retaining ridge (21) is immersed in the injected plastic material. Fourth, the fixed and movable dies are uncoupled and a cured molded article of the plastic material thus produced is released from the movable die (22). Due to the unique configuration of the retaining ridge (21), undesirable burrs (31) which are inevitably produced on the molded article are entirely positioned in a groove (4) which is formed in the article by the retaining ridge (21).
