Abstract

(57) [Summary] [Purpose] The purpose is to prevent rotation of the cassette tape when the cassette tape case is stored, by the pressing force such as the restoring force of the spring or elastic material. [Structure] A hermetically sealed cassette tape case that prevents rotation of the cassette tape by pressing the rotation stopper 5 of the cassette tape case against the claw 6 of the rotation transmission portion of the cassette tape by a force such as a restoring force of a spring or an elastic material. , And by using integrally molded spring and rotation stopper
It is a closed cassette tape case that simplifies the assembly process.

Description

[Detailed description of the device]

[0001]

[Usage field]

 The present invention relates to a closed type cassette tape case by reducing the height of a rotation stopper.

[0002]

[Prior Art]

 In the conventional cassette tape case rotation stopper, the rotation is stopped by inserting an obstacle into the rotation transmission portion (1) of the cassette tape to prevent the cassette tape from becoming entangled. For this reason, the opening and closing method was limited to the method of opening and closing the surface of the cassette tape case with the rotation stop or the facing surface, and it was difficult to form a closed cassette tape case.

[0003]

[Problems to be solved by the device]

 In the method of inserting an obstacle, the height of the rotation stopper (2) is increased, which has hindered the variety of cassette tape cases.

[0004]

[Means for Solving the Problems]

 The present invention adopts a method of preventing rotation by pressing the rotation stop against the rotation transmitting part of the cassette tape, thereby lowering the height of the rotation stop, and also providing a rotation stop and a spring for pressing the rotation stop. The main feature is that the cassette tape is inserted from the side by integrally molding. As a result, a closed cassette tape case that is easy to store and has a small number of manufacturing processes has been realized.

【Example】

 In FIG. 7, a cassette tape case 3 is inserted and fixed with a spring member 4 provided with a rotation stopper 5 or an integrally molded spring and a rotation stopper 8. The lid 15 of the cassette tape case 3 is opened and the cassette tape 13 is inserted. Then, the spring material 4 and the auxiliary spring 9 are spread out, and the cassette tape is fully inserted. When fully inserted, the rotation stopper 5 is pressed against the rotation transmitting portion 1 of the cassette tape by the spring member 4, as shown in FIG. A large number of shallow grooves formed on the tip of the rotation stopper 5 and the claws 6 of the rotation transmission portion 1 are engaged with each other, and rotation is prevented by frictional force (in the case of FIG. 1).

FIG. 2 is a set diagram when a large number of shallow grooves are not attached to the tip of the rotation stopper 5. The force of the spring member 4 acts in the pressing direction 7, and the tip end surface of the rotation stopper 5 is pressed against the claw 6 of the rotation transmission portion 1 to prevent rotation.

FIGS. 1, 2, and 3 are cross-sectional views taken along the line AA in FIG. FIG. 6 is a plan view of the closed type cassette tape case, and FIG. 7 is a cross-sectional view taken along the line WE.

Although the material and shape of the rotation stopper are arbitrary, the embodiment of the present invention is most effective in the form of FIG. 2 having a large number of shallow grooves as shown in FIG. And FIG. 4 is an enlarged view of the tip of the rotation stopper.

The present invention in which the rotation stopper 5 and the spring member 4 are integrally molded of synthetic resin or the like will be described. In FIG. 7, the spring material 4 and the rotation stopper 5 are integrally molded, and the integrally molded spring and rotation stopper 8 are set in the cassette tape case 3. The cassette tape case 3 and the spring and the rotation stopper 8 that are integrally molded are provided with irregularities so that they can be set simply by inserting them.

FIG. 8 is an elevational view of the integrally formed spring and the rotation stop 8, and the notch 10 is for facilitating movement of the rotation stop 5 in a direction that does not interfere with the insertion of the cassette tape. The auxiliary spring 9 serves to press the cassette tape against the rotation stopper 5. The width A14 is the thickness of the cassette tape near the rotation transmitting portion 1.

[0011]

【The invention's effect】

 As described above, the cassette tape case of the present invention enables the cassette tape to be inserted from the side by holding the rotation stop height and fixing it to the spring material, thus enabling a closed cassette tape case. Become. Further, by integrally molding the spring material and the rotation stopper, the manufacturing process and the assembling process can be simplified.
