However, in the case 7 described in Non-Patent Document 1, a storage space 9 for storing individual cartridges 1 is divided into a plurality of partition projections 11 and the cartridges 1 are stored in the storage space 9 in units of one turn. Met. That is, the cartridges are distributed and stored. For this reason, in the actual storing operation, the cartridges 1 are stored one by one, and there is a problem that usability is deteriorated particularly when there are a large number of cartridges 1.
Further, in the case 7, since the storage spaces 9 are partitioned one by one, the entire storage area (that is, the upper surface opening area of the case 7) is equally divided by the individual storage spaces 9. For this reason, in the case parts 13 and 15 at the extreme ends, almost all the loads of the storage cartridge are concentrated, resulting in poor impact resistance, and there is a problem that the shock absorbing ability at the time of dropping is lowered.
Furthermore, when the case 7 is stacked up and down, an appropriate rib is not formed. Therefore, when the case 7 is stacked up and down, stability is impaired.

  The present invention has been made in view of the above situation, and an object of the present invention is to provide a cartridge storage case that has high storage work efficiency while maintaining impact resistance, and is stable without load collapse.

Hereinafter, a preferred embodiment of a cartridge storage case according to the present invention will be described in detail with reference to FIGS.
FIG. 1 is an exploded perspective view of an upper case and a lower case separated from each other according to the present invention. FIG. 2 is a plan view of the upper case shown in FIG. 3 is an explanatory view of the upper case, FIG. 3 is a view for explaining the cartridge storage case, (a) is a view taken in the direction of arrow A in FIG. It is a principal part external view of a storage case.
The cartridge storage case 100 can be suitably used for storing, for example, a flat cartridge 21 in which a magnetic tape winding reel is provided.

  The cartridge 21 is provided with a magnetic tape winding reel (not shown) in such a direction that the axis is in the thickness direction. In the present embodiment, the case where the cartridge 21 is a square flat body will be described as an example, but the cartridge may be a rectangular flat body.

  The cartridge storage case 100 can be opened and closed by overlapping the upper case 23 and the lower case 25 having the same structure from above and below and engaging with each other. By engaging the upper case 23 and the lower case 25, a plurality of compartments 27 are formed therein. In the present embodiment, four compartments 27 are formed. As shown in FIG. 1, in each compartment 27, a plurality of cartridges 21 are juxtaposed in the thickness direction to hold a cartridge group 29 in a block shape. As shown in FIG. 1, the cartridge 21 is arranged with the tape take-out port facing upward so that the weak tape take-out port is on the center side of the compartment 27. More preferably, the tape outlets may be arranged to face each other in each compartment 27. In this case, the tape take-out port is directed toward the center of the cartridge storage case 100, so that the tape take-out port can be protected from an impact from the outside of the case.

  Here, one compartment 27 forms substantially the same storage volume as the volume of the cartridge group 29 composed of the five cartridges 21. Therefore, even if the cartridges 21 are randomly packed in the respective compartments 27, there are no partition walls for the individual cartridges 21, so that they can be easily inserted. For example, two to three cartridges 21 can be grasped and packed together, and the storage efficiency is significantly improved compared to the conventional product that is grasped and inserted one by one.

  In this way, as the plurality of cartridges 21 are stored together in a block shape, a surplus area that does not contribute to storage can be ensured as compared to the case where the plurality of cartridges 21 are distributedly stored in the same storage area. In the cartridge storage case 100, this surplus area is used as an impact absorbing portion (so-called crushable zone).

  That is, flanges 31, 31 that are shock absorbing portions are extended on both ends of the upper case 23 and the lower case 25 in the magnetic tape winding reel axial direction. Each flange 31 is provided with a handle opening 33 serving as a handle for carrying the case. In other words, the cartridge storage case 100 in which the upper case 23 and the lower case 25 are engaged can be carried with one hand taking the opening 33 and the other flange 31 being downward. It is possible. Further, the cartridge storage case 100 may be carried in the horizontal direction by grasping the handle openings 33 on both sides with both hands.

  As described above, when the cartridge storage case 100 is slid down from the hand when the cartridge storage case 100 is carried with the one handle opening 33 held with one hand and the other flange 31 positioned downward, the cartridge storage case 100 The lower flange 31 collides with the floor surface. At this time, the flange 31 serving as an impact absorbing portion is deformed by the load of the cartridge storage case 100 and the cartridge group 29, and the impact energy is absorbed by the deformation, and the impact on the stored cartridge 21 is reduced. ing.

  In general, the cartridge 21 is vulnerable to an impact applied in the reel axial direction. This is because there is a case where the tape pops out on the end surface of the wound tape, and when the tape hits the reel flange due to this tape jumping out, the magnetic tape can be smoothly wound and fed out. This is because it is obstructed, and in the worst case, reading and writing cannot be performed. In the present embodiment, the flange 31 serving as an impact absorbing portion is disposed in the reel axial direction of the cartridge 21 to improve the impact resistance in the reel axial direction that is vulnerable to impact. .

FIG. 3B is an external view of the main part of the cartridge storage case showing buffer ribs provided on the outer wall surface of the compartment.
In addition, buffer ribs 35 that protrude outward from the compartments 27 are formed on the wall surfaces of the compartments 27. Therefore, even when an object collides with the cartridge storage case 100 from the outside, a gap is formed between the outer wall surface of the case and the cartridge 21 by the buffer rib 35, and the buffer rib 35 serves as a cushioning material. The impact resistance is increased. In particular, as shown in FIG. 3B, buffer ribs 37 are formed at the corners of the compartments 27 so as to surround the ridges of the cartridge 21, and the cartridge storage case 100 with the cartridge 21 stored therein. An impact absorbing function is provided for effectively preventing deformation of the cartridge ridge line portion when the cartridge is dropped.

  The cartridge storage case 100 is composed of an upper case 23 and a lower case 25 having the same structure provided with convex portions (projections) 41 and concave portions (concave grooves) 43 that engage with each other. In the present embodiment, a ridge 41 and a groove 43 are formed in the upper and lower sides around the four compartments 27 so as to be symmetrical with respect to the case center line 45 of FIG. That is, the upper case 23 and the lower case 25 sandwich the center line 45, the U-shaped ridges 41 are continuously formed on one side, and the U-shaped concave grooves 43 are continuously formed on the other side. .

  When the upper case 23 and the lower case 25 having the same structure are combined up and down, the ridge 41 enters the groove 43 and both engage. Thereby, the compartment 27 is sealed, water resistance can be obtained, and it is also possible to float on water. Also, the cartridge 21 can be protected against dust, moisture, splashed water, and other harmful substances. That is, one case is used both as a lid and as a body. Accordingly, the cartridge storage case 100 in which the compartment 27 that can be opened / closed by the convex stripes 41 and the concave grooves 43 is formed by using one type of case formed by one mold.

  A partition 47 is provided between the compartments 27. The partition portion is formed with a shape and a thickness to be described later so that deformation with respect to an impact is easy. That is, the impact of the partition 47 is reduced when the partition 47 is deformed. The partition part 47 is interposed in any direction so that the falling direction may be from the side where the flange 31 is present or the direction perpendicular thereto. In the present embodiment, a cross-shaped partition portion 47 is formed so as to partition the compartments 27 arranged in four directions into four.

  The cartridge storage case 100 has a partition portion 47 between the compartments 27 in which the cartridge group 29 is stored, so that even when an impact is applied to each cartridge group 29 due to, for example, dropping, The partition portion 47 absorbs the impact, and the impact force due to the inertia between the cartridge groups 29 does not affect each other.

  By the way, the cartridge storage case 100 storing the cartridge group 29 is stored in a cardboard box (not shown) having an inner shape substantially the same as the outer shape. For this reason, chamfered portions 49 having inclined sides of approximately 45 degrees are formed on both sides of the flange 31 in order to improve the ease of taking out from the cardboard box. Thus, the cartridge storage case 100 accommodated in the cardboard box is formed with a triangular hole by the chamfered portion 49 between the inner wall surface of the cardboard box and can be easily taken out by inserting a finger. .

  Further, although not shown in the drawing, the chamfered portion 49 may have a configuration in which a knob is provided on the chamfered portion 49. In this case, when the upper case 23 and the lower case 25 having the same structure form a compartment 27 and are stacked in the vertical direction as shown in FIG. Thus, the engagement between the upper case 23 and the lower case 25 is easily released.

  Further, a step-bending portion is formed on the outermost periphery of the upper case 23 and the lower case 25 by slightly bending the periphery. Similar to the ridges 41 and the grooves 43, the stepped bent portion is formed so that the center line 45 is symmetrically formed on either one. Thereby, when the upper case 23 and the lower case 25 are overlapped, the stepped bent portion covers the other peripheral edge, so that the dustproof property and the waterproof property are improved.

  Furthermore, large and small square frame portions 53a and 53b that can be loosely fitted to each other are bulged on the outer bottom surface of each compartment 27. Thus, even when the cartridge storage case 100 is stacked in the vertical direction, the square frame portions 53a and 53b on the lower surface of the upper cartridge storage case 100 are fitted to the square frame portions 53b and 53a on the upper surface of the lower cartridge storage case 100. The relative lateral displacement is restricted to prevent collapse during stacking. This will be described in detail later.

  Each of the upper case 23 and the lower case 25 is made of an integrally molded product of a plastic resin. For this reason, the upper case 23 and the lower case 25 having the robustness to reliably protect the cartridge and the appropriate shock absorption can be easily and inexpensively mass-produced using a material that is relatively easy to handle. Yes.

  This plastic resin can contain, for example, any of polyethylene terephthalate, polypropylene, and polystyrene. By making the plastic resin either polyethylene terephthalate, polypropylene, or polystyrene, it becomes easy to obtain materials, and it can be recovered and reused after it becomes a waste product, enabling easy and inexpensive vacuum forming. .

  Moreover, it is preferable that a plastic resin is what has translucency. Thereby, even when the upper case 23 and the lower case 25 are engaged and the compartment 27 is in a sealed state, the cartridge 21 accommodated in the compartment 27 can be visually recognized from the outside, and the inside of the sealed compartment 27 is It is possible to easily grasp the cartridge storage status.

  In addition, by using a sheet of a plastic resin having a thickness of 0.5 to 2.0 mm, by forming by stretching, the minimum structural strength of the compartment that houses a plurality of cartridge groups is economically secured, The weight of the entire case can be minimized while satisfying the minimum strength. Moreover, by forming with the above-mentioned thickness, it is possible to appropriately deform when an external force is applied, and it is possible to optimally secure an impact absorbing action on the storage cartridge. That is, if it is thinner than this, the deformation becomes too easy and the impact absorbing effect is reduced. If it is thicker than this, it becomes difficult to deform and the impact force is directly transmitted to the storage cartridge. In this configuration, by setting the sheet thickness of the plastic resin to the above-described thickness, it is possible to form an optimal impact absorbing portion (crushable zone).

FIG. 4 is a diagram showing a procedure for storing a plurality of cartridges in such a cartridge storage case.
In (a), 100 is the lower case, 100u is the upper case, C1 is the first cartridge group to be stored in the same compartment in the cartridge storage case, and C2 is the first case to be stored in the same compartment in the cartridge storage case. 2 cartridge groups.
(B) shows a state in which the first cartridge group C2 and the second cartridge group C2 are respectively stored in the lower case 100u. Thereafter, the upper case 100u covers the lower case 100u.
(C) Thereafter, the upper case 100u is put on the lower case 100u.
In (d), it can be seen that the upper case 100u and the lower case 100u are integrated, and the first cartridge group and the second cartridge group are housed in separate compartments in a transparent cartridge housing case.

  FIG. 5 is a view for explaining a state in which the cartridge storage case according to the present invention integrated vertically in FIG. 4 (4) is stably stacked on another cartridge storage case. The front view of a cartridge storage case, (2) has each shown the front view of two cartridge storage cases stacked up and down.

  In (1), reference numeral 100 denotes a cartridge housing case that is integrated vertically, and the outer bottom surface of the lower case has a large rectangular frame 100 recess (53a, 53a in FIG. ) Bulges to the left and right of the figure, and is not visible on the paper surface of the figure, but a square frame part 100 convex (53b, 53b in FIG. ) Is bulged, and the convexity of the rectangular frame part 100 is dimensioned so that it can be fitted into the rectangular concave part formed at the center of the concave part of the rectangular frame part 100.

  On the other hand, on the outer upper surface of the upper case in (1) in the figure, a small square frame part 100 convex (53b, 53b in FIG. 1) that forms a square concave part at the center bulges to the left and right of the figure. The rectangular frame part 100 concaves (53a, 53a in FIG. 1) that are convex in the periphery forming a rectangular concave part in the center on the left and right sides of the opposite side are inflated. The convex of the rectangular frame portion 100 is dimensioned so that it can be fitted into the rectangular concave portion formed in the center of the concave portion of the rectangular frame portion 100.

  Therefore, when another cartridge storage case 100-2 is stacked on the upper and lower cartridge storage case 100-1 as shown in (2) of the figure, a small square frame on the cartridge storage case 100-1 is stacked. The convex portion 100 (53b, 53b in FIG. 1) is fitted into the rectangular concave portion formed in the center of the large rectangular frame portion 100 concave (53a, 53a in FIG. 1) below the cartridge storage case 100-2. The cartridge storage case 100-1 and the cartridge storage case 100-2 are integrated, so that the load does not collapse with a slight vibration.

6A and 6B are plan views for explaining the 100-convex and 100-concave components of FIG. 5, in which FIG. 6A is an upper case and FIG. 6B is a lower case (or vice versa). In the figure, the hatched portion represents a convex portion.
(A) 53 a 1 is a rectangular protrusion integrally formed with the upper case 23, and (b) 53 a 2 is a rectangular protrusion integrally formed with the lower case 25. The convex portion formed on the outer surface of the rectangular protrusion 53a1 is selected to have a size that fits into the concave portion formed on the inner surface of the rectangular protrusion 53a2. In order to fit, it is preferable that the outer dimension of the convex part and the inner dimension of the concave part are as close as possible (greater than 0 and 1 mm or less).

Therefore, the upper case 23 of FIG. 6 is overlaid on the lower case 25 as shown in FIG. A square frame portion 53a2 having a large convexity around each of which forms a square recess at the center bulges, while a small rectangular frame having a convex shape around each of the four corners on the outer upper surface of the upper case. The part 53a1 bulges out.
Therefore, as shown in (2) of FIG. 5, when another cartridge storage case 100-2 is stacked on the cartridge storage case 100-1 integrated vertically, a small square above the cartridge storage case 100-1 is obtained. The convex part of the frame part 100 (53b, 53b in FIG. 1) is formed in the center of the concave part (53a, 53a in FIG. 1) of the large rectangular frame part 100-2 below the cartridge storage case 100-2 and fits into the rectangular concave part. The cartridge storage case 100-1 and the cartridge storage case 100-2 are integrated, so that the load does not collapse with a slight vibration.

  Various combinations are conceivable for the combination of the small convex portion 53a1 and the large concave portion in FIG. In the figure, the hatched portion is a convex portion. In FIG. 6, four small convex portions 53 a 1 are arranged on the upper case 23, and four large concave portions 53 a 2 are arranged on the lower case 25. Such an arrangement may be adopted when the object to be stored has a problem with the top and bottom.

  Further, as shown in FIG. 1, two small convex portions 53 a and two large concave portions 53 b may be juxtaposed on the upper case 23 and the lower case 25, respectively. Such an arrangement may be employed when the stored item has a problem with the left-right orientation.

  Further, two small convex portions 53a and two large concave portions 53b may be arranged in a diagonal relationship with each other on the upper case 23 and the lower case 25, respectively. Such an arrangement may be adopted when the object to be stored does not matter upside down and left and right orientation.

  FIG. 6 shows an example of a combination of the same shape in which both the small convex portion and the large concave portion are square frame portions, but the present invention is not limited thereto, and the same shape may not be combined. FIG. 7 is a diagram illustrating combinations of various small convex portions and large concave portions.

In the figure, (a) is an example in which the inner rib 53b2 is accommodated in the outer rib 53b1, and the rib shape in that case may be round, triangular, or square.
(1) is an example in which a circular inner rib 53b2 is accommodated in a square outer rib 53b1, and (2) is an example in which a circular inner rib 53c2 is accommodated in a triangular outer rib 53c1. Unlike the case of FIG. 6, the above combination example is only in contact with the circular inner ribs 53b2 and 53c2 at the four points and three points in the outer ribs 53b1 and 53c2, respectively, and the other portions are free spaces. Therefore, even if a little dust or the like accumulates in the free space, there is no hindrance to the fitting, so it can be said that it is suitable for use in a dusty atmosphere.

In the figure, (a) is an example in which the inner rib 53b2 is accommodated in the outer rib 53b1, and the rib shape in that case may be round, triangular, or square. In the figure, the hatched portion is a convex portion.
(1) is an example in which a circular inner rib 53b2 is accommodated in a square outer rib 53b1, and (2) is an example in which a circular inner rib 53c2 is accommodated in a triangular outer rib 53c1. Unlike the case of FIG. 6 which is inscribed in the entire circumference, the above combination example is in contact with the circular inner ribs 53b2 and 53c2 at four points and three points in the outer ribs 53b1 and 53c2, respectively. In addition to the combination, the design effect is particularly excellent.

  (B) of FIG. 7 is an example in which the inner ribs 53d2, 53e2, and 53f2 are configured only by convex portions. That is, (1) is an example in which the circular convex portion 53d2 is accommodated in the square outer rib 53d1, (2) is an example in which the circular convex portion 53e2 is accommodated in the triangular outer rib 53e1, and (3) is in the square outer rib 53f1. Each shows an example in which the square convex portion 53f2 is accommodated. In FIG. 7B, since the inner ribs 53d2, 53e2, and 53f2 are only convex portions, the material is applied but the strength is increased. Therefore, the strength is required when the strength is required, and the design effect is also excellent. ing.
