[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a cassette tape multiple mounting device in a cassette tape recorder.

<Prior Art> Conventionally, a device for mounting a plurality of cassette tapes on a tape recorder has a mounting plate on a support A that is attached to a recording/reproducing device (tape recorder, etc.), as shown in FIGS. 5 and 6. A restraining step portion 3 ₁ is provided on the support piece 3 at the upper and lower positions of the front surface of 1;
At the same time, a pair of slightly lower restraining protrusions ₂ , 2 are protruded from the upper and lower intermediate positions of the retaining protrusions 32, and a pair are provided on both left and right sides of the back surface of the front plate 4 of the cassette holder B facing the support plate A. The restraint support parts 6, 6 are arranged oppositely,
Two sets of guide pieces 7, 8 facing each other are protruded from the restrainer support parts 6, 6 at a certain interval, and guide pieces 7, 8 are provided at the upper and lower positions of each of the guide pieces 7, 8. Positioning restraints 9 and 9 are slidably inserted through the pieces 7 and 8 to face the restraining protrusions 2 and 2.

A support piece 5 having an upper surface equal to that of the support piece 3 is sharply provided at the lower part of the holder front plate 4, and a first cassette tape a ₁ is inserted between both guide pieces 7 and 8.
At the same time, insert the second cassette tape _A2 between the guide piece 8 and the holder front plate 4, and place its lower end on the support piece 5 as before. Moreover, springs 10 and 11 are installed on the guide piece 8 and the back surface of the front plate 4, respectively, so that the cassette tapes a ₁ and a ₂ do not move.
It becomes loaded with bullets.

Then, the cassette holder B is moved in the direction of the arrow toward the support A, and when the restraining pieces 9, 9 come into pressure contact with the restraining protrusions 2, 2, the second cassette tape _a2 is pressed against the other piece of the restraining implement 9. At the same time, the top and bottom of the back surface of the first cassette tape _a1 come into pressure contact with the restraining step ₃₁ and the restraining protrusion ₃₂ , and are held by the spring 11. Ru.

In this case, the first and second cassette tapes
a ₁ and a ₂ are configured to move from the support piece 5 to the top of the support piece 3.

<Problems to be solved by the invention> However, in the above-mentioned conventional example, the assembly configuration of the restraint tool 9 and the guide piece 7 and the other end of the restraint tool 9 and the guide piece 8 is complicated and takes time to assemble. , the productivity is not good, and furthermore, the mounting plate 1 and the first cassette tape
Since the stopper 9 and the guide pieces 7 and 8 are interposed between the cassette tapes a ₁ and both cassette tapes a ₁ and a ₂ , it is impossible to reduce the distance between these parts, and if you try to narrow it, , it is necessary to reduce the wall thickness of the restraining member 9 and the guide pieces 7 and 8, respectively, which not only poses problems in terms of strength, but also poses a risk that the state in which the cassette tape is held becomes extremely unstable.

Moreover, in the above-mentioned complicated structure, it is difficult to integrate the restraining devices 9, 9, etc. into a housing in order to improve the strength, and at the same time, there is a risk of causing operational instability. It has many drawbacks such as:

SUMMARY OF THE INVENTION Therefore, the present invention addresses the drawbacks of the conventional example and provides a cassette tape multiple mounting device that can be downsized by simplifying the structure.

<Means for solving the problem> A cassette holder B that suppresses and holds the second cassette tape with a suppressing device that holds the first cassette tape, and a suppressing protrusion and a suppressing piece that suppresses the first cassette tape. It consists of a cassette holder support A having a stepped portion and a protruding restraining protrusion for restraining the restraining device.

<Operation> By pushing the cassette holder B loaded with the first and second cassette tapes toward the cassette holder support A, the restraining protrusion and the restraining step press the upper and lower parts of the first cassette tape. At the same time, the first cassette tape is restrained and held by the spring attached to the cassette holder, and at the same time, the other restraining pieces press the right and left sides of the restraining tool that holds the first cassette tape, and the restraining tool and the cassette holder are pressed together. The second cassette tape is held elastically by a spring attached to the second cassette tape.

<Embodiment> Hereinafter, the present invention will be explained in detail with reference to an embodiment shown in the drawings.A cassette holder support A to be attached to a recording/reproducing device (tape recorder), etc., has support pieces at upper and lower positions on the front surface of the mounting plate 1. A restraining step 3 ₁ and a restraining protrusion 3 ₂ are provided protrudingly provided on the mounting plate 1, and a pair of restraining protrusions 2, 2, . .

On the other hand, the cassette holder B supported by the support A has restraint support parts 6a facing each other on the left and right sides of the back surface of the holder front plate 4, and a hole is provided near the inner end of the restraint support part 6a. By inserting the protruding portion 13 of the box-shaped restraint tool 9a (see Fig. 2) into the horizontally long through hole or horizontally long recess 14 provided, the restraint tool 9a is allowed to have some play back and forth. Cassette holder B
When released from the cassette holder support A, the spring 11a presses the restraining tool 9a toward the back surface by the amount of play between the protrusion 13 and the oblong recess 14, and the spring 10
It is possible to prevent the elasticity of a and 11a from decreasing.

Here, reference numeral 15 is an auxiliary spring for the above operation, and there is no problem even if it is not used in practice.

Furthermore, the play space allows the holder B to be pressed against the support A, thereby absorbing variations between products.

In addition to holding the tape in this way, lower end support pieces 5a and 5b of the cassette tape are integrally formed on the lower edges of the restrainer support parts 6a and 9b, and further,
A spring 11a is provided on the opposing surface of the restraining device support parts 6a, 6a, and faces into the restraining device 9a through the notch opening (FIGS. 3 and 4) of the restraining device 9a, and restrains the first cassette tape _a1 . and a spring 10a which is located between the restraint member 9a and the holder front plate 4 and which restrains the second cassette tape _a2 are provided integrally or separately in a protruding manner.

Then, the inner end 12 of the restraint tool 9a and the spring 11a
A first cassette tape _a1 is inserted between the stopper 9a and the spring 10a, and a second cassette tape _a2 is inserted and held between the front surface of the restraining member 9a and the spring 10a.

Next, a series of operations of the mounting device having the above configuration will be described. First, as shown in FIG. 1, the first cassette tape _a1 and the second cassette tape
When inserting cassette tape a ₂ and pushing cassette holder B in the direction of cassette holder support A as shown by the arrow, both cassette tapes a ₁ and a ₂ are supported on support piece 3 in the middle and are pushed further. Then, the first cassette tape a ₁ comes into contact with the cutout step portion 3 ₁ and the restraining protrusion 3 ₂ and is pushed, and is elastically clamped by the spring 11a.

At the same time, the restraining protrusions 2, 2...
This presses the second cassette tape _a2 toward the spring 10a and clamps it there.

In this way, both cassette tapes a ₁ and a ₂ are held immovably in place.

<Effects of the invention> As described above, in the present invention, the left and right parts of the restraint tool that come into contact with the four restraining protrusions, as well as the upper and lower parts, are integrally formed in a housing shape. It operates smoothly without any damage, and is durable.
The deterrent action also becomes more reliable.

Furthermore, the structure of the attachment part between the restraint and the restraint support is simplified, productivity is improved, and
To reduce the amount of inclusions between the mounting plate 1 of the support A and the first cassette tape _a1 , as well as in the gaps between the first and second cassette tapes _a1 and _a2 , thereby sufficiently reducing the respective gaps. This makes it possible to easily reduce the thickness.

In addition, since there is a play in the attachment part between the restraint device and the restraint device support part to sufficiently absorb dimensional variations between products, operation is reliable even if the products are different, and the above When installing tapes a ₁ and a ₂ by the amount of play between the restraint and its support,
Since the springs 10a and 11a immediately act to restore the cassette holder to its original state when the cassette holder is separated from the support A of the cassette holder,
It is a highly practical idea that has many excellent effects, such as being able to prevent the elasticity of the spring from decreasing and being able to withstand long-term use.

Furthermore, when the auxiliary spring is applied, this effect becomes greater, and when there are no cassette tapes a ₁ and a ₂ , it is possible to suppress the occurrence of slight vibrations (vibrations) by pressing the restraint tool against the restraint support part. can. In addition, by making the deterrent transparent, the tape
You can check the presence or absence of a ₁ .
