ようにしたものである。Summary of the invention The invention comprises a cassette case consisting of upper and lower cassette halves for storing a tape feed reel and a take-up reel, and a lid body that covers an opening for drawing out the tape in the cassette case. A protrusion is integrally provided on the pivot shaft for opening and closing formed on the lid body, and the opening and closing of the lid body is controlled by elastic force while contacting the protrusion of the pivot shaft at a position outside the reel of the lower cassette half. When the lid is opened, the protrusion of the pivot shaft contacts the surface of the leaf spring and the lid opens upward, and when the lid has been opened, the leaf spring is elastically displaced by a predetermined amount. By doing so, a biasing force is always applied to the protrusion, and thus the lid body, in the direction of closing the lid, and the lid body is configured to automatically close when the tape cassette is removed. The tape cassette can be automatically assembled easily.

する。 FIG. 2 is a plan view schematically showing the internal structure excluding the upper half 3, in which 14 and 15 are the payout reel and take-up reel of the same structure, 16, 16a, 16b are the upper flanges of each reel, 17, 17a, 17b is a hub, 18, 18a, 18b are hub holes thereof, T shown by a dashed dotted line is a tape wound around each hub, 19,
Reference numerals 19a and 19b indicate lower flanges having, for example, square teeth 20 at a constant pitch on their peripheral surfaces, and the tape T from the feeding reel 14 is connected to the feeding side guide pin 2.
It is guided to the inside of the front plate 7 of the opening/closing lid 5 by 1a and 22a, and reaches the take-up reel 15 through guide pins 22b and 21b located at symmetrical positions on the take-up side. That is, when the opening/closing lid body 5 is opened as described above, the tape T' stretched between the feeding side guide pin 22a and the winding side guide pin 22b is exposed, and this stretching tape T ′ inside
The tape drawer body of the VTR body fits into the tape for loading. Therefore,
The inside of the tension tape T' is formed into a trapezoidal recess 23 into which the tape drawer is inserted.
and the inside of the cassette are separated by a partition plate 24. 25 is a tape sagging prevention plate extending from the lower surface of the lid upper plate 8. Needless to say, the tape slack prevention plate 25 functions when the lid 5 is closed, that is, when the cassette is not in use.

が加わるように構成する。 In the present invention, for example, integrally molded rotation support shafts 26 are provided on the inner surfaces of both side plates 6 of the lid body 5, and both rotation support shafts 26 are held and supported between the upper half 3 and the lower half 4. At the same time, a leaf spring 2 is attached to the lower half 4 side.
8, and this plate spring 28 is attached to one of the rotation support shafts 2.
6 to control the opening and closing of the lid body 5. That is, a cylindrical protrusion 27 is provided protrudingly on one rotation support shaft 26 for opening and closing formed on the lid body 5, for example by integral molding. A leaf spring 2 is installed near the dynamic support shaft 26.
Install 8. As shown in FIGS. 3 and 4, this leaf spring 28 has a base 29 attached to the lower half 4 with screws 3.
0, etc., a bent portion is provided and extends near the support shaft 29, and is configured such that a restoring force is applied in the left direction in FIG. 3 while making elastic contact with the protrusion 27 of the support shaft 26.

自動的に閉じられる。 FIG. 3 shows the lid closed state. When the tape cassette 1 is attached to a VTR body and the lid is opened, the protrusion 27 of the support shaft 26 comes into contact with the surface of the leaf spring 28 and rotates against the return force, causing the lid 5 to move upward. It opens to prepare for loading tape T'. In this state where the lid has been opened, the leaf spring 28 is displaced to the right by a predetermined amount as shown in FIG. A biasing force is applied in the direction of the lid. When the tape cassette 1 is removed from the VTR body, the lid 5 is automatically closed by the elasticity of the leaf spring 28.

完了する。 This tape cassette 1 is assembled in advance using the leaf spring 28.
Various parts are arranged inside the lower half 4 to which the lower half 4 is attached, and the lid body 5 is placed on the lower half 4 via its support shaft 26, and then the upper half 3 is fitted together to form the upper and lower halves. It is completed by combining them by appropriate means.
