The present invention is rotatably supported on a cassette case,
In a tape cassette that has a lid that opens and closes the front opening, the axes of the rotation axes of the pivots on both sides of the lid relative to the cassette cassette body are made different, thereby preventing the lid from being incorrectly attached to the cassette cassette body. This eliminates problems caused by vertically or horizontally asymmetric configurations and improves product yield.

けられている。 In FIG. 8, 1 generally indicates the case of a tape cassette for recording, for example, a PCM signal, and this cassette case 1 has an upper half 1a and a lower half 1b.
2a and 2b are reel hubs, 3 is a magnetic tape, and 4 is a lid provided on the front of the tape cassette, which in this figure is in a state where the front opening is closed. This lid 4 has a long plate-shaped lid portion 4a for closing the front opening of the tape cassette, and a shaft hole 5 for the rotation axis of the lid 4, which is bent from both ends of the lid portion 4a. It consists of a shaft support 4b. The lid 4 is made of a highly elastic plastic material, and by being curved toward the cassette case 1, it engages with the front opening of the cassette cassette 1 through elastic deformation, and remains stationary at a predetermined position to open the front opening. The area is closed. 6 indicates a rotation shaft portion of the lid 4;
The rotation shaft 6 is provided at a predetermined position on the cassette case 1.
また、第９図はこの例のテープカセツトの蓋４

In the tape cassette constructed in this way, the lid 4 is pivotally supported on the cassette cassette 1 by pivot shafts 6, 6 at both pivot supports 4b, 4b.
Since 6 has the same diameter, it is possible to assemble the lid 4 even in an inverted state, but if the lid 4 has a vertically or horizontally asymmetric configuration, it will be difficult to assemble it in an inverted state, resulting in a defective product. , there is a problem that the yield of the product decreases.
本考案はかかる点に鑑み、簡単な構成により、
カセツト匣体に対する蓋の誤装着を防止するよう

されると共に間隙が生じる状態となる。 In the closed state of the front opening 14 of the lid 17, the lid plate portion 17a is located at the upper and lower edges of the front opening 14 on its inner side, that is, the upper and lower halves 11a, 11b.
It is configured to be elastically deformed and abutted against the front edge of the front edge of the front edge of the front edge of the front end of the front edge of the front end of the front edge of the front end of the front edge of the front end of the front edge of the front edge of the front edge of the front end of the front edge of the front edge of the front end of the front edge of the front edge of the front end of the front end of the front edge of the front edge of the front end of the front edge of the front edge of the front edge of the front edge of the front edge of the front edge of resistance of resistance of biasing force. In addition, in this closed state, both side pivot arm portions 17
b, 17c are biased inward due to the deformation of the cover plate portion 17a, and the shaft support surfaces 20a, 2 of the cassette case body 11
This both-side pivot arm part 1 is in contact with 0b.
The outer surfaces of 7b and 17c are located substantially on the same plane as both side surfaces of the cassette case 11. Further, in the middle of the opening operation, when the lid plate portion 17a is brought into contact with the upper edge or the lower edge of the opening of the cassette case 11, the lid plate portion 17a is elastically deformed most greatly and locked. This state, that is, the dead point position is reached, and by exceeding this position, the cover plate portion 17a is rotated upward or downward in the restored state to be opened, resulting in a so-called click operation. In this state, both side pivot arm parts 17b and 17c are connected to the cover plate part 17.
Since the biasing force from a does not act, the cassette case 1
The contact with the shaft support surfaces 20a and 20b of 1 is released, and a gap is created.

成されている。 Therefore, in this example, when the lid 17 is in the open state, the projecting edge surfaces 20a 1 and 20b 1 , which are in contact with the inner surfaces of the both side pivot arm portions 17b and 17c, are attached to the cassette case 1.
The lid 17 protrudes from the shaft support surfaces 20a and 20b of the lid 17, and is configured to prevent sliding in the lateral direction in the open state. The projecting edge surfaces 20a 1 and 20b 1 are located at a portion separated from the both-side pivot arm portions 17b and 17c when the lid 17 is in the closed state and in its opening/closing operation state, and provide both-side pivot support due to the elastic deformation of the lid plate portion 17a. The arm portions 17b and 17c can be displaced without any trouble, and the lid 17 can be opened and closed reliably.

The rear half part c is formed as a fan-shaped surface that spreads forward from the periphery of the shaft holes 22a and 22b. On the other hand, the stopper edge surfaces 23a, 23b, on which the both-side pivot arm portions 17b, 17c of the pivot-support surface portions 20a, 20b of the cassette case 11 are locked in the open state, are moved to the rear half of the open position of the both-side pivot arm portions 17b, 17c. It is formed in a shape along the inclined side surface of the section, that is, in a symmetrical inclined surface shape vertically from the center, and the upper and lower ends are formed into vertical surfaces 23a 1 and 23b 1 . Therefore, the center portions of the stopper edge surfaces 23a, 23b are close to the end surfaces of the pivots of the both-side pivot arm portions 17b, 17c.

The shaft pin that pivotally supports the lid 17, that is, the cassette case 1
The lid 1 is provided protrudingly on both side shaft support surfaces 20a and 20b of the lid 1.
The shaft diameters of the two shaft pins 21a, 21b which pivotally support the both shaft support arm portions 17b, 17c of 7 are made different from each other, and the shaft diameters of both shaft support arm portions 17b, 1
Since the hole diameters of the shaft holes 22a and 22b of 7c are made different, it is possible to prevent a malfunction of reversal when attaching the lid 17 to the cassette case 11, and it is possible to store the tape cassette in the cassette magazine with side A and side B aligned, as in the tape cassette shown in the figure. If the lid 17 is configured vertically asymmetrically or horizontally asymmetrically as in the case where the lid 17 is configured to be vertically asymmetrical or horizontally asymmetrical, problems caused by incorrect attachment can be eliminated.

As described above, according to the present invention, in a tape cassette that is rotatably supported on the cassette cassette and has a lid that opens and closes the front opening, the axial diameter of the rotating shaft of the pivot on both sides relative to the cassette cassette is adjusted. By making the lids different from each other, it is possible to prevent problems caused by incorrect attachment when the lid is formed vertically or horizontally asymmetrically, and to improve workability during assembly.
