[Conventional technology]

When storing magnetic tape cassettes used for audio etc. , a storage case for magnetic tape cassettes made of plastic ( It is stored in a cassette storage case (hereinafter simply referred to as a "cassette storage case"). The cassette storage case is the magnetic tape cassette (hereinafter referred to as "cassette"). A magnetic head, etc. is inserted when a recording/playback device is loaded into a recording/reproducing device. a cassette front opening, and extending across the front opening. Since it has a magnetic tape mounted on it, dust will not come out from the front opening. It prevents it from entering the cassette and is located at the front opening. It is used for the purpose of protecting the magnetic tape and the entire cassette. It is.

0003 To explain the basic structure of a conventional cassette storage case, the cassette The storage case has a lid with a pocket into which the front opening of the cassette is inserted. and a pair of anti-rotation protrusions that fit into the shaft insertion hole of the cassette. It consists of a casing part that has been And the cassette storage case are the support shafts protruding from the left and right inner sides of the casing part and the ends of the pockets. By fitting the holes made through the side wall, the casing part and the front The storage cover can be opened and closed like a door. In addition, the cassette storage case has walls facing the front and back surfaces of the cassette. a cassette thickness increase, the spacing forming a front opening of the cassette; That is, it is configured to have an interval corresponding to the thickness of the trapezoidal part. For this reason , the thickness of the cassette storage case excludes the increased thickness of the cassette. It is quite large compared to the thickness of the cassette. Therefore, the above The set storage case is better than storing the cassettes naked. Requires fairly large storage space.

0004 This makes it difficult for general users to store said cassettes in a limited space. For example, if you are trying to control the If you want to store as many as possible, store them in the cassette storage case mentioned above. Sometimes there isn't. However, the cassette is not placed in the cassette storage case. If you store the cassette without storing it, dust can easily enter the cassette. It may deteriorate the recording and playback characteristics of the magnetic tape, and it may not absorb the shock when dropped. There were problems such as damage when received.

[0005] In order to solve the above problems, the applicant first developed a thin cassette. A storage case was proposed (Utility Model Application No. 163279, 1987, Utility Model Application No. 163279, 52782). This slim cassette storage case allows you to store your cassettes like never before. Store the cassette in the opposite direction and open the cassette storage case to remove the thickened part. At the same time, the recess that receives the thickened portion of the cassette is placed on the release side. This structure is formed on the upper and lower walls of the space. Said Utility Model Application No. 63-52782 Refer to Figure 4 for the improved cassette storage case described in the publication. To explain, the cassette storage case 11 has a lid having a pocket 14. The section 12 and the casing section 15 are similar to the conventional cassette storage case. The cassette of the lid part 12 and the casing part 15 is pivotally connected. A cassette 20 is placed on the open side of the walls 13 and 16 that widely face the front and back surfaces. Recesses 18, 18 are formed to receive the increased thickness portions 21. The recesses 18, 18 are formed inside the case so as to face each other. , a depth similar to that for receiving the cassette thickened portion 21 (also referred to as a trapezoidal portion). It is structured in various shapes. As a result, the cassette storage case 11 can close the recesses 18, 18. The distance between the removed wall portion 13 and the wall portion 16 is determined by increasing the thickness of the cassette. Construct the spacing to be very slightly larger than the thickness L2 of the parts other than the main part 21. It can be made much thinner than previous cases. follow In addition to reducing storage space compared to before, it also made it easier to use as a portable device. The selfishness has been greatly improved. However, according to the inventor's study, there are issues that need further improvement. It became clear that there was.

In this case, if it is a long piece of music, two or more Recorded separately on two or more cassettes, just like recorded on a vinyl record, Supplied as a set. However, the conventional cassette storage case only has one Only cassettes can be stored. Therefore, general users It is necessary to manage a set of tapes so that they do not fall apart, which is extremely difficult. It was inconvenient. In particular, language learning tapes, etc. are based on the learning program. In practice, a special management box is used. It is in a state of In this way, conventionally, multiple cassettes, that is, two or more cassettes, were stored at the same time. Regarding the cassette storage case, storage efficiency in terms of space is taken into consideration. The cassette is slim and can accommodate multiple cassettes. Set storage cases and the like did not have that technical concept. Also, the case is thinner As a result, the problem has generally been brought into sharp focus, and the cassette preservation Problems also arise with the protection function and operability when opening and closing.

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. Na Figure 1 is a perspective view of the cassette storage case, Figure 2 is the partition member and pocket. Figure 3 is a perspective view showing the shape of the cassette. 4 and 5 are cross-sectional views of essential parts. The feature of this embodiment is that two cassettes are stacked and stored, and the entire This is due to the thin structure of the body. And in explaining the implementation refers to the cassette 20 described with reference to FIG.

[0009] The configuration of the cassette storage case 1 in this embodiment can be roughly divided into specifications. A partition member 2 and pockets provided on both sides of the lower end of the partition member 2 4. A pair of casings rotatably attached to both ends of the pocket 4 It consists of a ringing section 3. The case storage case 1 includes the partition member 2. Since the structure is symmetrical around the center, each member is given the same reference numeral. I will explain.

0010 One end of the plate-shaped partition member 2, that is, in this embodiment, A pair of pockets 4 are formed on both sides of the lower end, and the other end, That is, the trapezoidal part 21 (cover) of the cassette 20 is located at the upper end as described later. A recess 5 is formed to receive the increased thickness of the set. Ru. The pair of casing parts 3 have protrusions 6 provided on the side plates 3a as pockets 4. to be inserted into the mounting holes 7 (shown in Figure 2) provided on the side surfaces of both ends. It can be mounted rotatably. Further, a locking recess 8 is formed near the protrusion 6, and a locking recess 8 is formed in the vicinity of the protrusion 6. When the locking part 3 is closed as shown in Figure 3, the lock formed in the pocket 4 It is configured to fit into the projection 9 for use. Therefore, the pair of cases Once the sing part 3 is closed, rotate it with your fingers to open it in the left and right direction. The cassette 20 will not open unless energized and will not open undesirably during use. Accidents such as damage can be prevented.

[0011] The wall portions 31 constituting the pair of casing portions 3 have anti-rotation protrusions. 32 is provided, and further the trapezoidal part 2 is provided in the closed state as shown in FIG. A recess 33 is provided for receiving 1. Note that the side plate 3 In a, a pair of hands are used for opening the casing parts 3. Hook portions 34 are provided, and these portions are attached to the cassette 20. This will be explained in sequence along with the storage operation.

0012 Next, storage of the cassette 20 will be explained. When storing two cassettes 20, a pair of the cassettes 20 are stored. Open the section 3 as shown in Figure 1, with each trapezoidal section 21 facing upward. In other words, insert it into the pocket 4 with the rear end facing down. This conclusion As a result, the two cassettes 20 are each positioned by the pocket 4. 3 and 4, and one side of each of the trapezoidal portions 21 is shown in FIGS. 3 and 4. As shown in FIG. be done. In this state, if the pair of casing members 3 are closed, FIG. As shown in FIG. stored inside. At this time, the rotation prevention protrusion 32 is attached to the cassette 20. Since the tape is inserted through the shaft insertion hole 22, it is possible to prevent the tape from sagging. complete casing.

[0013] What should be noted in this embodiment is that the two cassettes 20 It is in storage condition. That is, the recess 5 is formed in the partition member 2, The wall portions 31 of the pair of casing members 3, When the holding member 3 is closed, a recess 3 is formed at a position opposite to the recess 5. 3 is formed. Therefore, the cross-sectional structure at the position indicated by line A-A in Fig. As shown in FIG. Become accepted by 3. As a result, the thickness of each of the trapezoidal portions 21 is reduced by the recesses 5 and 33. So to speak, it seems like they are offset, and the two cassettes 20 are stored. The cassette storage case 1 can be made thin despite the fact that it is Wear.

[0014] On the other hand, at the position shown by line B-B in Fig. 3, as shown in Figs. The side surfaces of the pair of casing parts 3 touch both sides of the partition member 2. The upper end of the partition plate 2 is in contact with the handle part 34 so as to be sandwiched therebetween. It has a shape that stands out. For this reason, each finger of each hand is connected to a pair of fingers. They are applied to the handle portions 34 of the casing member 3 and are urged outwardly from each other. As a result, both the casing parts 3 can be opened to both sides. Ru. On the other hand, if you want to open either one of the pair of casing parts 3, If so, put your finger on the handle part 34 of the side you want to open, and then press the handle part 34 of the side you don't want to open. If so, place your fingers on the upper end of the partition member 2. As a result , the casing part 3 that you do not want to open is pressed against the partition member 2. It becomes like being disciplined. Therefore, the casing 3 that you want to open is It can be opened smoothly, but the casing 3 of the one you do not want to open is careless. The stored cassette 20 can be dropped without opening, etc. accidents can be prevented, and its operability is high.

[0015] Here, an example of the size of the cassette storage case 1 will be explained. Then, the width w1 remains unchanged compared to the conventional case. But the thickness Due to the formation of recesses 5 and 33, L2 is thinner than the thickness of two conventional cases. , it was possible to make it about 6 mm smaller. Volume of the cassette storage case 1 Although it contains two cassettes, it is different from the conventional one cassette. It was possible to keep the volume to about 1.53 times. In other words, for the volume of a cassette storage case containing one cassette, Two cassettes 20 can be stored with an increase of about 53%. others Therefore, the storage space for the two cassettes is reduced, and the operability is also improved. Also, since related cassettes 20 can be stored together, storage is easy. becomes easier.

[0016] Next, a second embodiment will be described with reference to FIGS. 6 and 7. In this embodiment, the joint structure of the side plates 3a of the pair of casing parts 3 is 6 and 7 are A-A in the embodiment.

[0017] That is, in the embodiment shown in FIG. 4, the pair of casings The seam of part 3 is a seam of flat surfaces. In this shape, Dust easily enters through the gaps, and if dust does enter, remove it from the front of the cassette 20. There is a high possibility that it will adhere to the magnetic tape (not shown) facing the surface opening 23. Not only that, but it also makes it easier for your fingers to get caught when opening the case. However, as shown in FIGS. 6 and 7, the pair of casings 3 The seams have an overlapping structure. According to this structure, from the seam It is difficult for dust to enter, improving dust-proofing measures, and this area (of the cassette) It becomes difficult to open the door by placing your finger on the corresponding part of the opening. This prevents fingers from touching the opening of the cassette.

[0018] Next, a third embodiment will be described with reference to FIGS. 2 and 8. This embodiment relates to the rotation prevention protrusion, and the partition Regarding the member 2, the recess 5 is deeply cut as shown by the dotted line a in Fig. 2. or when the cassette 20 is stored, the shaft insertion A hole b with a large diameter is formed at a position where the hole 22 is positioned. On the other hand, rotation prevention As for the stop protrusion 32, as shown in FIG. 8, an engagement structure is provided at the tip. Insert and engage the large diameter hole b, or insert the cut recess a. They are constructed so that they can be inserted through and engaged with each other.

[0019] According to such an engagement structure, the pair of casing parts 3 are closed. In this state, both the casing parts 3 are engaged by the anti-rotation protrusion 32. It comes to stop. That is, the engaging portions of both anti-rotation protrusions 32 are An appropriate fitting structure can be formed. Therefore, as described in the first embodiment, There is no need to intentionally provide a locking mechanism consisting of the hole 8 and the protrusion 9. Na The locking hole 8 is provided in the side plate 3a, and the shape of the hole 8 is The mounting position is a plate-shaped part and is mechanically weak, so it may be deformed, cracked, or chipped. Easy to get injured. However, the rotation prevention protrusion 32 is not shown in the figure. Since a protrusion, etc. that engages with the hub pawl is formed, the machine can be removed from the side plate 3a. High mechanical strength.

[0020] In addition, due to the structure in which the rotation prevention protrusions 32 are connected, the rotation prevention protrusion 32 is connected to each other. A support rod is formed in the middle of the case, increasing the strength of the case. It is also possible to reduce the wall thickness of the case. Therefore, this embodiment According to , it eliminates the need for special handling and improves usability. . Note that there are no particular limitations on the fitting structure between the rotation prevention protrusions 32. It's not something you can do.
