However, the case 7 described in Non-Patent Document 1 is provided with a flange portion 17 on the outer peripheral portion thereof, and is accommodated in a state where the flange portion 17 is almost in contact with the inner wall of the cardboard box in order to save space and absorb impact. Yes. In this state, for example, when the cardboard box is opened after being transported, even if it is attempted to remove the case 7 from the cardboard box, there is almost no part between the flange portion 17 and the inner wall of the cardboard box. It ’s hard to take it out. Furthermore, if a hand is forced, the finger may be damaged at the edge portion of the case 7.
In the case 7, a storage space 9 for storing individual cartridges 1 is partitioned into a plurality of partition projections 11, and the cartridges 1 are stored in the storage space 9 in units of one turn. In other words, the cartridges 1 are distributed and stored, so that in the actual storage 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.
The present invention has been made in view of the above situation, and an object of the present invention is to obtain a cartridge storage case that improves the take-out property from the cardboard box and has high storage and handling work efficiency.

The above-mentioned subject concerning the present invention is attained by the following composition.
(1) A cartridge storage case for storing a flat cartridge in which a magnetic tape winding reel is installed, and holds at least a group of cartridges in a block shape by juxtaposing a plurality of the cartridges in the thickness direction. A cartridge storage case in which one compartment, a flange projecting parallel to the cartridge thickness direction on at least a part of the outer periphery of the compartment, and at least one gripping portion formed on the flange.

  According to this cartridge storage case, for example, when it is taken out from a cardboard box or the like, it can be easily pulled out via a gripping portion formed on at least one of the flanges protruding from the compartment. Of course, since the edge portion is not grasped, there is no possibility of damaging the finger. Further, unlike the conventional case, it is not necessary to individually store a plurality of cartridges, and a plurality of cartridges that are stacked and held in the thickness direction can be collectively stored in the compartment.

(2) The cartridge storage case according to (1), wherein the gripping portion is a gripping hole portion or a gripping notch portion obtained by cutting the flange.
According to this cartridge storage case, when the cartridge is taken out from the cardboard box or the like, it can be easily pulled out by inserting a finger or the like into the holding hole or the holding notch formed in the flange. Furthermore, in the case of the gripping hole, the storage case can be lifted with one hand.

(3) The above-mentioned compartment is formed by overlapping the upper case and the lower case having the same structure provided with a convex part and a concave part that engage with each other and engaging the convex part and the concave part. The cartridge storage case according to (1) or (2).

  According to this cartridge storage case, for example, the concave and convex portions that are mutually engageable are formed symmetrically with respect to the center line of the case so that the concave and convex portions can be engaged by overlapping the same case. One storage container can be configured. Similarly, in the configuration of the storage case, cases having the same structure are used as the upper case and the lower case. That is, one case is used both as a lid and as a body. Accordingly, it is possible to configure a cartridge storage case in which a compartment that can be opened and closed by the concavo-convex portion is formed using one type of case formed by one mold.

(4) The cartridge storage case according to any one of (1) to (3), wherein a plurality of the compartments are formed, and the compartments are connected to each other via a partition portion.

  According to this cartridge storage case, there is a case where an impact is applied to each cartridge group due to, for example, dropping or the like because the partition portion is interposed between the compartments in which the cartridge groups including a plurality of cartridges are stored. However, the partition portion absorbs the impact, and the impact force due to the inertia between the cartridge groups does not affect each other.

(5) The cartridge storage case according to any one of (1) to (4), wherein each of the upper case and the lower case is made of an integrally molded product of a plastic resin.

  According to this cartridge storage case, high-accuracy upper and lower cases can be mass-produced easily and inexpensively using materials that are relatively easily available.

(6) The cartridge storage case according to the above (5), wherein the plastic resin contains any one of polyethylene terephthalate, polypropylene, and polystyrene.

  According to this cartridge storage case, since the plastic resin is any one of polyethylene terephthalate, polypropylene, and polystyrene, the material can be easily obtained and easy and inexpensive vacuum molding can be performed.

(7) The cartridge storage case according to the above (5) or (6), wherein the plastic resin has translucency.

  According to this cartridge storage case, even when the upper case and the lower case are engaged and the compartment is sealed, the cartridge stored in the compartment is visible from the outside, and the cartridge storage in the sealed compartment is possible. The situation can be easily grasped.

(8) The cartridge storage case according to any one of (5) to (7) above, which is formed by stretching a sheet of the plastic resin having a thickness of 0.5 to 2.0 mm.

  According to this cartridge storage case, the minimum structural strength of the compartment for storing a plurality of cartridge groups is economically secured by forming a sheet of a plastic resin having a thickness of 0.5 to 2.0 mm by stretching. In addition, 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 moderately deform when an external force is applied, and it is possible to optimally secure an impact absorbing action on the cartridge. That is, if it is thinner than this, the deformation becomes too easy and the impact absorbing effect is lowered. If it is thicker than this, it becomes difficult to deform, and the impact force is directly transmitted to the 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).

  The cartridge storage case according to the present invention can be easily pulled out by the grip portion when taking out from the cardboard box or the like. In addition, unlike the conventional case, there is no need to individually store a plurality of cartridges, and therefore, a plurality of cartridges that are stacked and held in the thickness direction can be collectively stored in a compartment, which enables efficient storage in a short time. Furthermore, by providing a gripping hole, it is possible to carry the storage case with one hand, and the work efficiency of storage and handling can be greatly improved.

Hereinafter, preferred embodiments of a cartridge storage case according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is an exploded perspective view of an upper case and a lower case separated from each other according to the present invention, and FIG. 2 is a plan view of the lower case shown in FIG. FIG. 3 is a partially broken perspective view when the cartridge storage case shown in FIG. 1 is pulled out.
A cartridge storage case (hereinafter also simply referred to as “storage case”) 100 according to the present embodiment stores a flat cartridge 25 in which a magnetic tape winding reel 23 around which a magnetic tape 21 is wound is provided. In this case, it can be suitably used.

  In the cartridge 25, a magnetic tape winding reel 23 is provided in the direction in which the axis is in the thickness direction. In the present embodiment, a case where the cartridge 25 is a square flat body will be described as an example. However, the cartridge 25 may be a rectangular flat body.

  The storage case 100 can be opened and closed by overlapping the upper case 27 and the lower case 29 with the same structure from above and below. By engaging the upper case 27 and the lower case 29, a plurality of compartments 31 are formed therein. In the present embodiment, four compartments 31 are formed. In each compartment 31, as shown in FIG. 1, a plurality of cartridges 25 are juxtaposed in the thickness direction to hold a cartridge group 33 in a block shape. As shown in FIG. 1, the cartridge 25 is arranged with the tape take-out port facing upward so that the weak tape take-out port is located at the center of the compartment 31. More preferably, the tape outlets may be arranged to face each other in each compartment 31. In that case, the tape outlet is directed toward the center of the storage case 100, and the tape outlet can be protected from an impact from the outside of the case.

  In the present embodiment, one compartment 31 forms substantially the same storage volume as the volume of the cartridge group 33 composed of five cartridges 25. Therefore, even if the cartridges 25 are randomly packed in each compartment 31, there is no partition wall for the individual cartridges 25, so that the compartments 31 can be easily inserted. For example, two to three of the cartridges 25 can be grasped and packed together, and the working efficiency of storage is remarkably improved from the conventional product that is grasped and inserted one by one.

  As described above, the plurality of cartridges 25 are stored in a block shape, and have the same storage area as that of the storage case 7 including the flange portion (the type determined by the standard). As compared with the case where the storage is distributed and stored, a surplus area that does not contribute to storage can be secured. In the storage case 100, this surplus area portion is used as a shock absorbing portion (so-called crushable zone), that is, as a wider area like the flange 35 of the present embodiment compared to the flange of the storage case 7.

  Flange 35, 35, which is an impact absorbing portion, extends in the lateral direction on both ends in the axial direction of the magnetic tape winding reel 23 of the upper case 27 and the lower case 29. Further, each flange 35 is formed with a gripping hole portion 37 which is a gripping portion whose center portion is cut into a square hole shape. That is, the storage case 100 in which the upper case 27 and the lower case 29 are engaged is carried with one hand (finger) in one of the gripping holes 37 and the other flange 35 facing downward. Can be lifted and lifted. In contrast, the storage case 100 can be held horizontally by holding the holding holes 37, 37 on both sides with both hands, and can be lifted vertically by holding the holding hole 37 with one hand. .

  As described above, when the storage case 100 is slid down from the hand when the storage case 100 is carried with the one gripping hole 37 held with one hand and the other flange 35 positioned downward, the storage case 100 is The lower flange 35 collides with the floor surface. At this time, the flange 35 serving as an impact absorbing portion is deformed by the load of the storage case 100 and the cartridge group 33, and the impact energy is absorbed by the deformation, so that the impact on the stored cartridge 25 is moderated. Yes.

  In general, the cartridge 25 is vulnerable to an impact applied in the reel axial direction, which is the thickness direction. This is due to the winding of the magnetic tape 21, and the winding tape end face is not wound with the complete flat body aligned and a tape pop-out occurs on the winding tape end face. As a result of this tape jumping, the end of the tape hits the flange of the magnetic tape winding reel 23 due to an impact, and if the tape continues to be stored in a state where it is crushed or bent, the magnetic tape 21 can be smoothly wound. This is because the feeding is hindered, and further, the recording is disturbed. In the present embodiment, by providing a flange 35 serving as an impact absorbing portion in the reel axial direction of the cartridge 25, the impact resistance in the reel axial direction that is vulnerable to impact is improved. .

  The storage case 100 includes an upper case 27 and a lower case 29 having the same structure provided with a convex portion (projection) 43 and a concave portion (concave groove) 45 that are engaged with each other. In the present embodiment, a ridge 43 and a groove 45 are formed in the upper and lower sides around the four compartments 31 symmetrically with respect to the case center line 47 of FIG. That is, the upper case 27 and the lower case 29 have a case center line 47 sandwiched between them, a U-shaped ridge 43 is continuously formed on one side, and a U-shaped groove 45 is continuously formed on the other side. Yes.

Further, in the present embodiment, a cross-direction partition 49 is formed so as to partition the compartments 31 arranged in four directions into four.
On the outermost periphery of the upper case 27 and the lower case 29, a step bending portion 51 is formed by slightly bending the peripheral edges into a curved shape. The step bent portion 51 is formed on either one of the case center lines 47 symmetrically as in the case of the ridge 43 and the groove 45 described above. Thereby, when the upper case 27 and the lower case 29 are overlapped, the stepped bent portion 51 covers the other peripheral edge, so that the dustproof property and the waterproof property are improved.

  Furthermore, large and small square frame portions 53 and 55 that can be loosely fitted to each other are bulged on the outer bottom surface of each compartment 31. Accordingly, even when the storage case 100 is stacked in the vertical direction, the rectangular frame portions 53 and 55 on the lower surface of the upper storage case 100 are fitted to the square frame portions 53 and 55 on the upper surface of the lower storage case 100, Relative lateral displacement is regulated to prevent collapse during stacking.

  Each of the upper case 27 and the lower case 29 is made of an integrally molded product of a plastic resin. For this reason, the upper case 27 and the lower case 29 having a robustness for reliably protecting the cartridge 25 and an appropriate shock absorption property can be easily and inexpensively mass-produced using a material that is relatively easy to handle. ing.

  This plastic resin can contain, for example, any of polyethylene terephthalate, polypropylene, and polystyrene. The plastic resin is either polyethylene terephthalate, polypropylene, or polystyrene, making it easy to obtain materials, and can be recovered and reused after being discarded, enabling easy and inexpensive vacuum forming. Become.

  Moreover, it is preferable that a plastic resin is what has translucency. Thereby, even when the upper case 27 and the lower case 29 are engaged and the compartment 31 is in a sealed state, the cartridge 25 stored in the compartment 31 can be visually recognized from the outside, and the sealed compartment is sealed. The storage status of the cartridge 25 in the cartridge 31 can be easily grasped.

  Moreover, the minimum structural strength of the compartment 31 which accommodates the several cartridge group 33 is economically ensured by forming by a drawing process using the sheet | seat of a plastic resin with a thickness of 0.5-2.0 mm. In addition, the weight of the entire case can be minimized while satisfying the minimum strength. In addition, by forming with the above 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 cartridge 25. That is, if it is thinner than this, the deformation becomes too easy and the impact absorbing effect is lowered. If it is thicker than this, it becomes difficult to deform, and the impact force is directly transmitted to the cartridge 25. 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).

  As shown in FIG. 3, the storage case 100 storing the cartridge group 33 is stored in a cardboard box 80 having an inner shape substantially the same as the outer shape. Then, when the storage case 100 is taken out after the cardboard box 80 is opened, it can be easily pulled out by inserting a finger or the like into the holding hole 37 formed in the flange 35. Further, in order to further improve the take-out property from the cardboard box 80, chamfered portions 57 having inclined sides of approximately 45 degrees are formed on both sides of the flange 35. As a result, the storage case 100 accommodated in the cardboard box 80 is formed with a triangular hole by the chamfered portion 57 between the inner wall surface of the cardboard box and can be easily taken out by inserting a finger. ing.

FIG. 4 is a partially broken perspective view when a storage case showing another configuration of the gripping part is pulled out.
In this case, the flange 35 is formed with a gripping cutout portion 61 that is a gripping portion cut from the center portion to the edge of the flange 35. The gripping notch 61 has a function of facilitating pulling by inserting a finger or the like when the storage case 100 is taken out after the cardboard box 80 is opened. In this case, it is preferable that the gripping notches 61 and 61 on both sides are grasped and pulled out with both hands.

  Therefore, according to the cartridge storage case 100 described above, when it is taken out from the cardboard box 80, it can be easily pulled out by the gripping hole 37 and the gripping notch 61 which are gripping portions. In addition, since the four compartments 31 for holding the cartridge group 33 in a block shape are formed by juxtaposing the plurality of cartridges 25 in the thickness direction, the case 7 is the same as the plurality of cartridges 25 are grouped in a block shape. Compared to the case where a plurality of cartridges 25 are distributed and stored in this storage area, a surplus area that does not contribute to storage can be secured. Then, by utilizing this surplus area portion as a flange for an impact absorbing portion (so-called crushable zone), it is possible to absorb an impact when the case is dropped and to improve the impact resistance against the cartridge 25. In addition, unlike the prior art, it is not necessary to individually store a plurality of cartridges 25. Therefore, a plurality of cartridges 25 that are stacked and held in the thickness direction can be collectively stored in the partition chamber 31, and efficient in a short time. Good storage is possible, and storage work efficiency can be greatly improved.
