Description

BOX TO ACCOMMODATE CASSETTE ' BACKGROUND OF THE INVENTION FIELD OF THE INVENTION The present invention relates to a cassette housing suitable for accommodating a tape cassette, such as, for example, a compact audio cassette and the like, and particularly, a cassette for accommodating cassettes of a slider type to accommodate a cassette. of tape, by laterally inserting the tape cassette from an insert mouth portion provided on one side thereof.

DESCRIPTION OF THE RELATED TECHNIQUE In recent years, in a box for accommodating cassettes to accommodate and maintain a compact audio cassette, a cassette for accommodating cassettes of a slider type for laterally inserting a cassette from an insert mouth portion provided on one side of the cassette. it has been put into practice. The structure of the box to accommodate conventional cassettes of lateral type will be shown in Figure 1 to Figure 5.

- - In Figures 1 to 5, reference number 1 indicates a box 1 for accommodating cassettes and a compact audio cassette (which will be referred to below, simply as a cassette) 10, is accommodated in box 1 to accommodate cassettes inserted laterally from an insert mouth portion 2 provided on one side thereof of the box 1 to accommodate cassettes. First of all, the structure of the cassette 10 will be explained. As shown in Figure 1, insertion holes 12 of the buoy driving shaft are formed on the left and right of a cassette housing 11 of the cassette 10 and corresponding to the holes 12 of insertion of the driving shaft of the hub, a pair of hubs 14 for winding a magnetic tape 13 are rotatably accommodated within the housing 11 of the cassette. On the front surface of the housing 11 of the cassette an opening portion 15 is formed through which a magnetic tape 13 is exposed, while inside the cassette housing 11, a tape transit path is formed in a manner where the magnetic tape 13 driven out of the hub (side supply bin) 14 on one side is wound around the hub (lateral winding bucket) 14 on the other side through the opening portion 15.

- - A magnetic head and the like are to be inserted into the opening portion 15 from one side of the cassette cover. In order to ensure the thickness of a portion into which the magnetic head and the like are to be inserted, the swollen trapezoidal positions 16 swelling towards the upper and lower sides of the surfaces are formed in the front portion of the housing 11. of the cassette. The box 1 for accommodating cassettes in which the cassette 10 is inserted is structured by joining an upper 1A half and a lower IB half. The upper half 1A is a molded plastic product which is for example molded of GPPS (general purpose polystyrene) as its material and also, the lower half IB is a molded plastic product which is molded eg of HIPS (Shock-proof polystyrene) as its material. The upper half 1A and the lower half IB are integrally joined by means of ultrasonic welding and the like, while in a state to be joined. Then, the insert mouth portion 2 is provided on one side of the side surface of the box 1 to accommodate cassettes with its surface being fully open, and the cassette 10 is inserted - laterally from the box 1 to accommodate cassettes from the insert mouth portion 2, in a sliding manner. The box 1 for accommodating cassettes is such that the cassette 10 accommodates therein almost without any slack. For this purpose, on the respective internal surfaces of the upper half 1A and lower half IB inside the box 1 to accommodate cassettes, respectively the concave grooves 3a and 3b are formed to escape the swollen portions 16 of the cassette 10, in one direction side, that is, in the direction of cassette insertion. Also, almost in a central portion of the upper half 1 of the box 1 for accommodating cassettes, a long opening portion 4 of an oblong shape is formed in the cassette insertion direction. When the cassette 10 is to be removed from the box 1 to accommodate cassettes, the cassette 10 is pushed out by placing a finger (eg, a thumb) from the opening portion 4. In addition, a tab 5 of stopping inside the case 1 to accommodate cassettes in order to prevent the cassette 10 from unexpectedly jumping out from a state of the cassette 10 that fits into the case 1 to accommodate cassettes. The stop tab 5 is projected completely formed in the lower IB half and is - provides a convex coupling portion 5a in a tip end portion thereof. Then, in the state of cassette 10 that is being accommodated in cassette 1 to accommodate cassettes, the convex coupling portion 5a of engaging stop tab 5 is engaged, as shown in Figure 5 with a edge of a portion 18 of opening in which a wrong erase protection detection fingernail 17 is provided for the cassette 10, which holds the cassette 10 in a slightly latched state in the case 1 to accommodate cassettes, thereby preventing the cassette 10 from jumping outwardly unexpectedly (leave) box 1 to accommodate cassettes. In addition, a rotation stop member 6 is equipped within the case 1 to accommodate cassettes to prevent the magnetic tape from loosening by blocking unnecessary rotation of the hubs 14 in the cassette 10. The rotation stop member 6 is a product molded plastic that is molded, for example, of PP (polypropylene) as its material and is structured in such a way that the rotating stop projection tabs 8 corresponding to the driving bore shaft insertion holes 12 of the cassette 10 are form projectingly in a portion 7 of the base plate to be able to rise and fall elastically, and portion 7 - of the base plate is fixed by caulking and fixed to the caulking projections 9 provided projectingly almost in a central portion within the lower half IB. Then, when cassette 10 is inserted into the box 1 for accommodating cassettes, the rotating stop projection tabs 8 are pushed down by the cassette 10. Furthermore, when the cassette 10 is completely accommodated in the cassette 1 to accommodate cassettes, since the insertion holes 12 of the driving shaft 10 of the cassette cube correspond to the projecting tongues 8 of rotation stop, respectively, the projecting tongues 8 of rotation stop are elastically returned to an erect state and engage with the coupling projection tabs 14a on an internal circumference of the cubes 14 to block the rotation of the cubes 14. With the box 1 for accommodating conventional cassettes mentioned above, because the projecting tongues 8 of stopping rotation are converted into a state of being pushed down each time the cassette 10 is pushed into it and pulled out from it, a state of deformation so called debit What happens in the fatigue in the projecting tongues 8 -detention of rotation and in that case, the tongues 8 - - Rotating stop projections are almost never returned to an erection state when the cassette 10 has been fully accommodated and has been converted to a state of _not coupling with the cubes 14, with the result that it becomes impossible to prevent the cubes Turn unnecessarily. Also, in a case where the projecting tongues 8 of rotation stop are incompletely raised, depending on the circumstances, the tip ends of the projecting tongues 8 of rotation stop are locked in a clearance between the cubes 14 and hub-driving arrow insertion holes 12 and are bent and folded, and, as a result, in this case likewise there is the loss of function to prevent the cubes 14 from spinning unnecessarily.

COMPENDIUM OF THE INVENTION The present invention is implemented in view of these problems and its object is to provide a box for accommodating cassettes capable of reliably preventing the cube from turning unnecessarily while the cassette is in a state of being accommodated therein. In order to achieve the aforementioned object, according to the present invention there is provided a box for accommodating cassettes which is structured in such a manner as to accommodate a cassette by laterally inserting the cassette from an insert mouth portion which is provided on a surface side of the same and wherein the rotational stop projecting tabs coupled with the cassette cubes to prevent them from rotating, are provided in a manner that are capable of rising and falling, and wherein each of the projecting tabs of Rotation arrest consists of two tabs that are provided in a parallel manner in a cassette insertion direction as a set. - With the box for accommodating cassettes in accordance with the present invention, being structured in this way, even in a case where one of the projecting stop-rotation tabs does not engage with the cube because it does not return to a state Erect or bent or folded, it is possible to safely prevent the hub from spinning unnecessarily by attaching another tab to the hub.

- DESCRIPTION OF THE PREFERRED MODALITY Next, an embodiment of the present invention will be explained in detail with reference to Figure 6 to Figure 11. A fundamental structure of a box for accommodating cassettes shown in the embodiment is the same as that of the box for accommodating cassettes of the conventional example . That is, a box 1 for accommodating cassettes of the present embodiment consists of joining a top half 1A and a bottom half IB. In this case, the upper half 1A is a molded plastic product which is for example molded of GPPS (general purpose polystyrene) as a material and also, the lower half IB is a molded plastic product which is molded, for example, of HIPS (Shock-proof polystyrene) as the material. The upper half 1A and the lower half IB are further integrally joined by means of ultrasonic welding and a similar means in a state of being joined. Then, an insert mouth portion 2 is provided on one side of the side surface of the box 1 to accommodate cassettes with its surface being fully open, and a cassette is inserted laterally - - in the case 1 to accommodate cassettes from the insert mouth portion 2 in a sliding or sliding manner. The cassette accommodating box 1 is formed in such a way that the cassette 10 is accommodated therein with almost no slack. For this purpose, on the sides of the inner surface of the upper half 1A and the lower half IB inside the box 1 for accommodating cassettes, respectively concave grooves 3a and 3b are formed to escape the swollen portions 16 of the cassette 10, in a lateral direction, that is, in a cassette insertion direction. Here, particularly in the case 1 to accommodate cassettes of this example, the concave slots 3a and 3b are provided symmetrically on both left and right sides of the cassette insertion direction, which leads to a structure in which the cassette 10 can insert in any of the orientations. That is, Figure 9A shows a state in which the cassette 10 is accommodated in the cassette 1 to accommodate cassettes in a manner in which the swollen portions 16 are oriented towards the left side of the cassette insertion direction, while the Figure 9B shows a state in which the cassette 10 is accommodated in the case 1 to accommodate cassettes in a manner in which the swollen portions 16 are oriented towards the right side of the cassette. cassette insertion direction and therefore, being able to insert and accommodate the cassette 10 in any of the orientations in the cassette 1 to accommodate cassettes, a user does not have to ensure the orientation of the cassette 10 each time the cassette is inserted. 10 and can uniformly insert cassette 10 at one time under any of the circumstances, without having to mention in a dark place. Also, in the case 1 to accommodate cassettes, since the molded portions of the concave grooves 3a and 3b are formed of a thin thickness and the thin portions due to the concave grooves 3a and 3b exist on both left and right sides of the address of cassette insertion, the amount of plastic used as the molding material is reduced compared to the prior art, thus making it possible to reduce costs by that amount as well as achieving lightening. Also, almost in the central portion of the upper half 1A of the box 1 to accommodate cassettes, an oblong shaped portion 4 is formed along the cassette insertion direction. When the cassette 10 is to be removed from the box 1 to accommodate cassettes, the cassette 10 is pushed out by placing a finger (eg, a thumb) from the opening 4.

- - In addition, a stop tab 5 is provided inside the case 1 to accommodate cassettes in order to prevent the cassette 10 from unexpectedly jumping out in a state where the cassette 10 is accommodating therein. The stop tab 5 is formed integrally in the lower half IB and a convex coupling portion 5a is provided in the tip end portion thereof. Then, in a state of the cassette 10 that is being accommodated in the cassette 1 to accommodate cassettes, the convex coupling portion 5a of the detent tab 5, as shown in Figure 10, engages with a edge of the portion 18 of opening wherein a wrong erase protection detecting fingernail 17 of the cassette 10 is provided, which holds the cassette 10 in a slightly latched state in the case 1 to accommodate cassettes, thereby including cassette 10 jumping out unexpectedly (leave) box 1 to accommodate cassettes. Since the box 1 for accommodating cassettes of the present example has, as mentioned above a structure in such a way that the cassette 10 can be inserted in any of the orientations corresponding thereto the stop tab 5 is symmetrically provided as 5 (L), 5 (R) on both left sides and right of the cassette insertion direction. That is, Figure 10A shows a state in which the cassette 10 is accommodated in the cassette 1 to accommodate cassettes in a manner wherein the swollen portions 16 face the left side of the cassette insertion direction. In this case, the stop tab 5 (R) on the right side of the cassette insertion direction engages with the opening portion 18 of the cassette 10 in order to retain the cassette 10 (during this time, the tab 5 ( L) of stopping on the left side of the cassette insertion direction escapes from cassette 10 because it is undergoing elastic deformation). Also, Figure 10B shows a state in which the cassette 10 is accommodated in the cassette 1 to accommodate cassettes in a manner wherein the swollen portions 16 are oriented towards the right side of the insertion direction of the cassette. In this case, the stop tab 5 (L) on the left side of the cassette insertion direction engages with the opening portion 18 of the cassette 10 to retain the cassette 10 (during this time, the tab 5 (R) of detention on the right side of the cassette insertion direction is escaping from - - cassette 10 because it is undergoing elastic deformation). With the box 1 for accommodating cassettes of this embodiment, as noted above, in cases where the cassette box 10 is inserted therein in any of the orientations, the cassette 10 can be safely retained in the box 1 to accommodate cassettes and prevents jumping out of box 1 to accommodate cassettes. In addition, inside the cassette housing 1 for accommodating cassettes, a rotation stopping member 6 is provided to prevent the magnetic tape from being released by unnecessary rotation of blockage of the cubes 14 in the cassette 10. The stop member 6 Rotation is a molded plastic product that is molded, for example, of PP (polypropylene) as a material and structured in such a way that the rotation stop projection tongues 8 corresponding to the insertion holes 12 of the arrow driven Cartridge hub 10, are formed projectingly in portion 7 of the base plate to be able to rise and lower elastically. The portion 7 of the base plate is fixed by caulking and fixed to the caulking projections 9, which are - they project substantially in the central portion of the interior of the lower half IB. Then, when the cassette 10 is inserted into the cassette 1 to accommodate cassettes, the rotational stop projection tabs 8 are pushed downward by the cassette 10. When the cassette 10 is fully accommodated in the cassette 1 to accommodate cassettes, due to that the cassette driving arrow insertion holes 12 of the cassette 10 correspond to the projecting tongues 8 of rotation stop respectively, the projecting tongues 8 of rotation stop elastically return to the erect state and engage the projecting tabs 14a in the circumference of the cubes 14_ to block the rotation of the cubes 14. Also, as shown in Figure 7, the base plate portion 7 of the rotation stop member 6 is constructed in such a way that grooves 7a cut into shape are formed of the letter "U" around the projecting tongues 8 of stopping rotation so that when the projecting tongues 8 of det When the rotation is pushed downwardly by the cassette 10, the portions surrounded by the cutout grooves 7a are folded downwards to assist in the fall of the projecting tongues 8 for stopping rotation. Meanwhile, the concave portions that escape correspond to the slots 7a cut off are respectively provided on the side of the inner surface of the lower half IB. Particularly, in the rotation stopping member 6 of this example, each of the rotational stop projection tabs 8 consists of two tabs which are provided in parallel in the insertion direction of the cassette as a set. That is, each of the projecting tongues 8 of rotation stop consists of a first tongue 8a and a second tongue 8b that is provided aligned within the first tongue 8a. The second tab 8b is almost the same shape as that of the first tab 8a and is also formed a little smaller in width, as well as shorter in height than the first tab 8a. Also, the shapes of the tip end portions of both the first tab 8a and the second tab 8b are formed in a curved line state (an arc state). The rotational stop projection tabs 8 are both provided in the centerline of the cassette insertion direction. In this case a width ti of the first tongue 8a is formed equivalent to or a little smaller than a width t2 of a common portion (a diagonally shaded portion) of the insertion holes 12 and 12 'of the buoy driving shaft when the two - cassettes 10 and 10 'overlap to be oriented in reverse one with respect to another, as shown in Figure 11. Therefore, a state wherein the cassette 10 is being accommodated in the cassette accommodating box 1, in cases where the cassette 10 is inserted in any of the orientations, the tabs 8 Rotation stopping projectors are inserted into the hub-driven arrow insertion holes 12 to engage with the cubes 14. That is, as shown in Figures 9A and Figure IDA, when the cassette 10 is accommodated in a box 1 to accommodate cassettes with the swollen portion 16 facing the left side of the cassette insertion direction, the two tabs 8a and 8b of the respectively straightly rising rotation stopping tabs 8 are inserted into the insertion holes 12 driving arrow of the cassette hub 10, and engaging in one of its side portions with the projecting tongues 14a coupling the cubes 14 to block the unnecessary rotation of the 14. Also, as shown in Figure 9B and Figure 10B, even when the cassette 10 is in a condition of being accommodated in the case 1 to accommodate cassettes with the swollen portions 16 facing the side - - right of the cassette insertion direction, the two tabs 8a and 8b of the upright rotating stop projection tabs 8 are inserted into the cassette drive date insertion holes 12 of the cassette 10 and are engaged in their other side portions with the projecting tongues 14a of coupling of the cubes 14 and blocking the rotation of the cubes 14. In this way, with the box 1 for inserting cassettes of the example, in cases where the cassette 10 is inserted in any of the orientations, the cubes 14 are prevented from turning unnecessarily by the projecting tongues 8 of stopping rotation as the magnetic tape is prevented from loosening. Then, particularly with the box 1 for accommodating cassettes of this example, the projecting tongues 8 for stopping rotation of the rotation stop member 6 each comprise two tabs 8a and 8b and since the two tabs 8a and 8b are coupled simultaneously with the cubes 14, it is possible to securely prevent the cubes 14 from turning unnecessarily. Also, even in the case where a tab outside the two tabs 8a and 8b of the rotation stopping tabs 8 does not engage with the cubes 14 by not returning to the erect state as well as being bent and folded, another tab is erect to mate with the - cubes 14 and, therefore, cubes 14 are reliably prevented from turning unnecessarily. Further, since the rotation stopping tabs 8 each consist of two tabs 8a and 8b, when the rotation stop member 6 is fed by a partial feed device in the assembly process to manufacture the box to accommodate cassettes. , the projecting tongues 8 of rotation stop never lock in the cutout grooves 7a of another rotation stop member 6. Therefore, it is possible to prevent this accident where the partial feeding device is plugged with a plurality of rotation stopping members that are stacked one on top of the other, which is effective in terms of productivity. In addition, in one embodiment, since the tips of the tip end of the two tabs 8a and 8b of the rotational stop projecting tabs 8 are formed in a curved line state (an arc state), at the time that the cassette 10 is being inserted into or being withdrawn from (the cassette 1 to accommodate cassettes) even though the cassette 10 has been rubbed by the tip end portions of the two tabs 8a and 8b of the projecting tongues 8 of stopping rotation I do not know They easily fix the dents on the surface of cassette 10, which is effective to protect the cassette. An example of the embodiment of the present invention has been explained up to now, but the present invention is not limited to the example. For example, in the above-mentioned example, the box has been shown in which the present invention is applied to accommodate cassettes and wherein the cassette can be inserted in any of the orientations, but the present invention can also be applied to a cassette to accommodate cassettes. shown in the prior art wherein the cassette 10 can insert in only one orientation. In addition, as shown in Figures 12 to 17, cassette housing 1 is provided with a stop member 25 to prevent cassette 10 from jumping out suddenly in a state where cassette 10 is housed therein. The stop member 25 is provided in the recess slot 3b formed in the lower half IB of the case 1 to accommodate cassettes together with a "U" notch groove 26 formed in the lower half IB. In addition, the stop member 25 is provided with a coupling protrusion 25a that is coupled with a winch shaft insertion hole 19 of the - protruding portion 16 of the crest 10, as will be explained later in the distal end portion of the slot 26. As will be evident from Figure 16, the engagement protrusion 25a of the stop member 25 has a front edge portion or tip 25a ?, which is formed as a sloping surface (taper surface). In addition, the coupling boss 25a is formed with a groove (hole) 27 similar to a recess (concave) in the central upper end portion thereof. When the cassette 10 is inserted into the cassette 1 for inserting cassettes, the stop member 25 is pushed down once by the protruding portion 16 of the cassette 10 and then, when the cassette 10 has been fully inserted into the cassette 1 for inserting. cassettes, the coupling protrusion 25a engages with the winch shaft insertion hole 19 of the protruding portion 16 of the cassette 10 by a resilience (resilient resilient force) of the stop member 25. In this manner, cassette 10 is retained in cassette 1 to accommodate cassettes in a slightly latched state so that cassette 10 can be prevented from suddenly jumping out (slipping out) of cassette 1 to accommodate cassettes.

- - As described above, the cassette 1 for accommodating cassettes has a structure capable of inserting the cassette 10 and independently of the directions of the cassette 10. For this purpose, the stop member 25, i.e., the members 25 (L) and 25 (R) of arrest are formed symmetrically on both right and left sides in the direction of insertion of the cassette so as to correspond to the aforementioned structure. More specifically, Figure 15A shows a state where the protruding portion 16 is located on the left side of the cassette insertion direction and the cassette 10 is housed in the cassette 1 to accommodate cassettes. In this case, the coupling protrusion 25a of the member 25 (L) on the left side of the cassette insertion direction engages with the insertion hole 19 of the winch shaft of the cassette 10 to retain the cassette 10. For another FIG. 15B shows a state in which the protruding portion 16 is located on the right side of the cassette insertion direction that the cassette 10 is housed in the box 1 to accommodate cassettes. In this case, the mating protrusion 25a of the stop member 25 (R) on the right side of the cassette insertion direction engages the hole - - 19 for inserting the winch shaft of the cassette 10 in order to retain the cassette 10. As described above, in the cassette 1 for accommodating cassettes, even in the case where the cassette 10 is inserted therein from any of the directions, the cassette 10 is retained securely in the cassette 1 to accommodate cassettes in order to prevent the cassette 10 from jumping out of cassette 1 to accommodate cassettes. The box 1 for accommodating cassettes has a structure in which the stop member 25 is formed in the recess groove 3b, and engages with the insertion hole 19 of the winch shaft of the protruding portion 16 of the cassette 10. therefore, in a state where the cassette is housed, the arresting member 25 does not remain in a state that deforms for a prolonged period. Therefore, no aged deformation is generated in the stop member 25 so that the cassette 10 can be safely stored and retained in the box to accommodate cassettes. In addition, the cassette housing 1 has a structure in which the stop member 25 is pushed once downward by the protruding portion 16 of the cassette 10 when the cassette 10 is being inserted into the cassette 1 to insert cassettes and then, it engages with the insertion hole 19 of the winch shaft. Thus, - - even in the case where there is unevenness in the wall thickness of the protruding portion 16 of cassette 10, cassette 1 for accommodating cassettes allows for unevenness in a wall thickness. Also, in box 1 for accommodating cassettes, the mating protrusion 25a of stop member 25 has edge 25a? Distal tip (front) that is formed towards an inclined surface and in this way the coupling protrusion 25a of the stop member 25 can be coupled uniformly with and released from the insertion hole 9 of the winch shaft. Likewise, the shape of the 25th bank? Distant (front) of the mating boss 25a of the stop member 25 can be a curved surface, as shown in Figure 18. Likewise, the recess slot 27 is formed in the central portion of the distal end of the boss 25a coupling of the holding member 25 and in this way it is possible to prevent a so-called inhibited mark (shrinkage) (i.e., deformation by shrinkage of the resin after molding) generated from a structure in which the mating boss 25a is a thick wall. Therefore, the coupling protrusion 25a is securely engaged with the insertion hole 19 of the winch shaft of the cassette 10, and an appearance of the cassette 1 can also preferably be maintained to accommodate cassettes even if the protrusion 25a is seen coupling from the back side of box 1 to accommodate cassettes. In addition, cassette housing 1 is provided therein with a rotation stopping member 6 which inhibits unnecessary rotation of cassette 14 of cassette 10 in order to prevent a magnetic tape from loosening. The rotation stop member 6 is a molded plastic product which is molded of a PP material (polypropylene) and a base plate 7 is formed with a rotation stopping protrusion 8 corresponding to the insertion hole 12 of the driving shaft of the cassette cube 10. The rotation stopping protrusion 8 is formed in a state of being assembled in order to be able to be raised and lowered elastically. The base plate 7 is fixed to a clamping boss 9 (caulking) projecting from an inner surface of the lower half IB in approximately the central portion thereof and therefore, the rotation stop member 6 is fixed in the lower IB half. When the cassette 10 is inserted into the cassette 1 for inserting cassettes, the rotation stop protrusion 8 is pushed and dropped downwards by the cassette 10. Then, when the cassette 10 is fully inserted in the cassette 1 to accommodate cassettes, the The insertion hole 12 of the cassette driving shaft arrow 10 corresponds to the rotation stop protrusion 8 and in this way the rotation stop protrusion 8 is elastically returned to an upright state, and engages a protrusion 14a of coupling projected from an inner peripheral surface of the hub 14 and therefore rotation of the hub 14 can be inhibited. In the rotation stop member 6 in accordance with the present embodiment, the rotation stop protrusion 8 is composed of three pieces projects 8a, 8b and 8c and has a structure in which two pieces thereof engage with the hub 14 to inhibit a rotation of the hub 14. Of more specific, as shown in Figure 15, in a state where the protruding portion 16 is located on the left side of the insertion direction of the cassette and the cassette 10 is housed in the box 1 to accommodate cassettes, two pieces 8a and 8b of the rotation stopping member 8 engage with the boss 14a of the hub 14 to inhibit a rotation of the hub 14 (during this time a remaining part 8c is in - - a state of being pushed and falling down through cassette 10). On the other hand, as shown in Figure 15B, in a state where the protruding portion 16 is located on the right side of the insertion direction of the cassette and the cassette 10 is housed in the box 1 to accommodate cassettes, two parts 8b and 8c of the rotation stopping member 8 are coupled with the boss 14a of the hub 14 to inhibit a rotation of the hub 14 (during this time a remaining part 8a is in a state of being pushed and falling downwards by the cassette 10). As described above, in box 1 for accommodating cassettes, even in the case where the cassette 10 is inserted into it from any of the directions, it is possible to safely inhibit unnecessary rotation of the hub 14 by the Rotation stopping protrusion 8 and therefore, a magnetic tape is prevented from loosening. In addition, in the present embodiment, it is evident from the figures, each end-end portion of the pieces 8a, 8b and 8c of the rotation stop protrusion 8 is formed as a curved shape (circular arc). In this way, when the cassette 10 is inserted into the cassette 1 for inserting cassettes (or removed from cassette 1), even when cassette 10 is rubbed against the distal end portion of each of the parts 8a, 8b and 8c , the surface of cassette 10 is hard enough to be damaged; in other words, it is effective for the protection of the cassette 10. A preferred embodiment of the present invention has been described above; however, the present invention is not particularly limited to the aforementioned embodiment. For example, in the aforementioned embodiment, the box 1 for accommodating cassettes has a structure in which the mating protrusion 25a of the stop member 25 engages with the insertion hole 19 of the winch shaft of the protruding portion 16 of the cassette 10, and in this way cassette 10 is retained in cassette 1 to accommodate cassettes. The box 1 for accommodating cassettes may have a structure in which the mating protrusion 25a of the stop member 25 engages with the positioning reference hole 20 of the protruding portion 16 of the cassette 10 and thus the cassette 10 is retained in box 1 to accommodate cassettes. As is evident from the explanation given above, in the box for accommodating cassettes of the present invention, when the cassette is housed in the box to accommodate cassettes, the stop member is - coupled with the hole of the protruding portion of the cassette, and in this way the cassette is retained in the box to accommodate cassettes. In this structure, the detention member does not remain in a state of being deformed for a prolonged period; due to this reason, no aged deformation is generated in the stopping member. Therefore, the cassette is retained securely in the box to accommodate cassettes so that the cassette can be prevented from jumping out suddenly. - In addition, with the box for accommodating cassettes of the embodiment, the width Wl of the opening mouth portion 4 (see Figure 12) is formed larger than in a conventional one. That is, the width Wl of the opening mouth portion 4 is formed larger, as shown in Figure 11, than the width dimension W2 for the portion combining a common portion and an uncommon portion (diagonally shaded portion). ) of the insertion holes 12 and 12 'of the buoy driving shaft of the two parts of the cassettes 10 and 10' which are made when the two cassettes 10 and 10 'are superimposed on respectively inverse orientations and as a result when the cassette 10 is in a state of being accommodated in cassette 1 to accommodate cassettes, in cases where cassette 10 is inserted in any of the orientations, which - provides a structure such that the insertion holes 12 of the casing driving shaft 10 of the cassette 10 are completely exposed from the opening mouth portion 4. In this way, with the box to accommodate cassettes of the mode, since the buoy driving arrow insertion holes 12 never become a state of being hidden, even when the cassette 10 is inserted in any of the orientations, it is possible to pushing the cassette 10 out evenly by engaging the finger in the hub-driving arrow insertion holes 12 when trying to remove the cassette 10. Meanwhile, in this embodiment, even when the relationship between Wl and W2 occurs as Wl > W2, Wl = W2 is also recommended. As explained above, in the box for accommodating cassettes having a structure in which the cassette is accommodated by inserting laterally from the insert mouth portion provided on one side thereof, and inside thereof the rotational stopping projecting tabs that engage with the cubes in the cassette to prevent its rotation, are provided to be able to be raised and lowered, the present invention forms the rotational stopping projecting tabs with two tabs that are provided - in a parallel manner in the insertion direction of the cassette as a set so that the cubes can be prevented more safely from turning unnecessarily, and therefore, provide the cassette housing with high reliability that can be provided by the present invention. Having described the preferred embodiments of the present invention with reference to the accompanying drawings, it will be understood that the present invention is not limited to the aforementioned embodiments and that various changes and modifications may be effected therein by a person skilled in the art. without deviating from the spirit or scope of the present invention, as defined in the appended claims.
