Description

  The present invention relates to a cartridge storage case for storing a flat cartridge in which a magnetic tape winding reel is installed.

Conventionally, when stacking and packaging one-reel type magnetic recording tape cartridges, as shown in FIG. 17, each cartridge 101 is stored in a case 103 in units of one roll, and a plurality of cases 103 are packed in a cardboard box 105. And buffered.
However, in the case of such integrated packaging, since the cartridge 101 is stored in the cardboard box 105, it is necessary to open the cardboard box 105 in order to check the presence / absence, type, etc. of the cartridge 101. was there. In addition, when the cardboard box gets wet, the cardboard box sucks water and breaks, or the cartridge 101 contained therein and even the magnetic tape get wet.

In order to solve such a problem, for example, as shown in FIG. 18, Non-Patent Document 1 discloses a storage case 1 for collecting and packaging cartridges formed of transparent plastic that does not decrease case strength even when wet. It is disclosed.
In this storage case 1, the cartridges are erected independently one by one, so that even a cartridge with a fraction of one, two, etc. can be stably held and stored.
However, the storage case of Non-Patent Document 1 has a problem that the packaging form becomes large because ribs are provided to stand the cartridge independently for each roll.
Further, in the actual storage operation, the cartridges must be stored one by one, and there is a problem that the use is not good when a large number of cartridges are stored.

Therefore, as a result of intensive studies, the present inventor has previously proposed a magnetic recording tape cartridge collective packaging case in Patent Document 1 and the like. According to this proposal, it is possible to prevent dust from entering the magnetic recording tape cartridge and to prevent damage to the stored magnetic recording tape cartridge because of its excellent shock absorption. Will improve.
The cartridge collective packaging case can stably store a cartridge group consisting of a plurality of cartridges in the compartment, but it is not assumed to store a fractional number of cartridges such as one roll, two rolls, etc. Since there is a clearance between the cartridge and the inner wall surface of the compartment even if it is stored, there is a problem that the cartridge of the fraction cannot be stably stored and it is currently desired to solve it. is there.

On the other hand, FIG. 5 shows one compartment 27 in the conventional storage case. In FIG. 5, the inner wall surface of each compartment 201 on the side in contact with the cartridge 21 is formed flat. Since the cartridge 21 is supported by the surface (wide area), the cartridge side wall may be damaged when the cartridge is stored.

  In addition, as shown in FIG. 6, it is preferable to have a contact prevention protrusion 203 for preventing contact between adjacent cartridges between the compartments 201 and 201. Thereby, it is possible to prevent adjacent cartridges from coming into contact with each other when being stored in the compartment or during transportation.

Next, FIG. 7 shows another exploded perspective view in which the upper case and the lower case of the cartridge storage case of the present invention are separated. In this embodiment, a state is shown in which a cartridge group 29 composed of five cartridges 21 is juxtaposed and stored.
Since the inner wall of each compartment has flexibility, it can be easily deformed when the cartridge group is lightly press-fitted and the block-like cartridge group 29 composed of five cartridges can be stably stored.
Here, FIG. 8 shows a state in which one cartridge group 29 is accommodated in one compartment 27. In this case, by shrink-wrapping the entire cartridge group 29, even if the partition between the compartments strongly contacts the surface (entire side wall) other than the ridge line portion of the cartridge group during storage, the surface of the cartridge is damaged. Can be prevented.

  As described above, according to the user's order, the cartridge storage case of the present invention is selected efficiently from one cartridge, a block-shaped cartridge group composed of a plurality of cartridges, or a combination thereof, and efficiently. It can be stored stably and the convenience can be greatly improved.

FIG. 9 is a schematic cross-sectional view of a cartridge storage case in which an upper case 23 and a lower case 25 are overlaid. FIG. 10 is a schematic cross-sectional view showing a state where the cartridge is stored in the cartridge storage case of FIG.
In this cartridge storage case, the upper case 23 and the lower case 25 are overlapped from above and below, so that the partition portion 47 in the upper case 23 and the partition portion 47 in the lower case 25 come into contact with each other. A certain compartment 27, 27 is formed. The wall surface of the compartment formed by the abutment of the partition 47 does not have a space communicating with the adjacent compartment. For this reason, even when dust enters one of the plurality of compartments, it does not enter another adjacent compartment.
Further, the upper case 23 and the lower case 25 are overlapped with each other, so that the contact portion where the partition portion 47 and the partition portion 47 contact each other exhibits flexibility, and is deformed when an impact is applied from the outside ( By bending, the impact is effectively absorbed and the impact force is prevented from being transmitted to the cartridge in the independent space.

  The compartment which is an independent space is formed by engaging the partition part of the upper case and the partition part of the lower case. For example, as shown in FIG. 11, the partition part 47 a in the upper case has a convex part 145 and a concave part 148, and the partition part 47 b in the lower case that engages with each other has a convex part 149 and a concave part 146. Then, when the upper case and the lower case are overlapped from above and below, the convex portion 145 enters the concave portion 146, the convex portion 149 enters the concave portion 148, and both are engaged to form a sealed independent space. A chamber is formed.

Further, as shown in FIG. 12, the partition portion 47 a in the upper case has a convex portion 145, and the partition portion 47 b in the lower case that engages with each other has a concave portion 146. When the upper case and the lower case are overlapped from above and below, the convex portion 145 enters the concave portion 146 and engages with each other to form a compartment which is a sealed independent space.
In addition, as shown in FIG. 13, the partition part 47 a in the upper case has a convex part 145 and a convex part 148, and the partition part 47 b in the lower case that engages with each other has a concave part 146 and a concave part 149. Yes. Then, when the upper case and the lower case are overlapped from above and below, the convex portion 145 enters the concave portion 146, the convex portion 148 enters the concave portion 149, and both are engaged to form a sealed independent space. A chamber is formed.

  Here, the upper case and the lower case shown in FIG. 11 are cartridge housing cases having the same structure formed by one mold. Further, the upper case and the lower case shown in FIGS. 12 and 13 are not one type of mold having the same structure, but a mold capable of forming a recess in the partition part of the lower case, and a convex part in the partition part of the upper case. Is formed using two types of molds, that is, a mold capable of forming a film. In addition, you may form a recessed part later by cutting in the partition part of the cartridge housing case of the same structure shape | molded with one metal mold | die, or affixing a convex part.

Moreover, it is preferable that the partition part 47 has a cleavable part that can separate adjacent independent spaces from each other, and the compartment 27 that is an independent space can be separated by the severable part. For example, in FIG. 11, a perforation 151 is provided between the convex portion 145 and the concave portion 148 (between the concave portion 146 and the convex portion 149). In FIG. 13, a perforation 151 is provided between the convex portion 145 and the convex portion 148 (between the concave portion 146 and the concave portion 149).
By cutting along the perforations 151 of these partition portions, the compartment 27 which is an independent space can be separated while maintaining its independent state, and can be used as a small cartridge storage case which is not bulky. .

Each compartment 27 can hold a group of cartridges 29 in which a plurality of cartridges 21 are arranged side by side in the thickness direction as shown in FIGS. As shown in FIG. 7, the cartridge 21 is preferably 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. It is more preferable to arrange them to face each other every 27th. As a result, 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.
Further, as shown in FIGS. 1 and 7, the compartment 27 is in a state where 45 to 55% (substantially half) of the height of the standing cartridge 21 is exposed to the outside from the compartment 27. The cartridge can be stored. Thereby, since the cartridge vertically arranged in the compartment protrudes substantially half from the lower case, it is easy to take out the cartridge from the lower case, and it is not necessary to provide a notch for taking out the cartridge.

  In this embodiment, one compartment 27 forms substantially the same storage volume as the volume of the cartridge group 29 composed of the five cartridges 21. Therefore, the working efficiency of storage is remarkably improved from the conventional product that is grasped and inserted one by one.

  Thus, the same storage area as that of the conventional storage case 1 shown in FIG. 18 including the flange portion (the type determined by the standard) is included in the amount of the plurality of cartridges 25 stored together in a block shape. Thus, it is possible to secure a surplus area that does not contribute to storage as compared with the case where a plurality of cartridges are stored in a distributed manner. In the storage case 100, this surplus area portion is wider as an impact absorbing portion (so-called crushable zone), that is, wider than the flange portion 11 of the storage case 1 shown in FIG. It is used as an area.

  As shown in FIG. 2A, flanges 31, 31 that are shock absorbing portions extend in the lateral direction on both ends in the axial direction of the magnetic tape winding reels of the upper case 23 and the lower case 25. The flanges 31, 31 are formed with gripping holes 33, 33 which are gripping parts with the central part cut into a square hole shape. In other words, the storage case 100 in which the upper case 23 and the lower case 25 are engaged is carried with one hand (finger) in one of the gripping holes 33 and the other flange 31 facing downward. Can be lifted and lifted. On the other hand, the storage case 100 can be held horizontally by holding the holding holes 33, 33 on both sides with both hands, or can be lifted vertically by holding the holding hole 33 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 33 held with one hand and the other flange 31 positioned downward, the storage case 100 is 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 storage case 100 and the cartridge group 29, and the impact energy is absorbed by the deformation, so that the impact on the stored cartridge 21 is reduced. Yes.

  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 unwound when it is crushed or bent. 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 which is vulnerable to the impact.

As shown in FIG. 1, buffer ribs 38 are formed on the side surfaces of the storage case 100 perpendicular to the thickness direction of the cartridge 21. In the present embodiment, two buffer ribs 38 are also formed in each compartment 27 in a convex shape. These are simultaneously formed when the upper case and the lower case are formed of a thermoplastic resin.
The buffer rib 38 can absorb the impact by bending itself when an impact in the width direction of the cartridge 21 is applied when an object collides with the compartment 27 from the outside. That is, the buffer rib 38 forms a gap between the outer wall surface of the case and the cartridge 21, and the space serves as a cushioning material to improve impact resistance.

  The storage case 100 is composed of an upper case 23 and a lower case 25 having substantially 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. 2A. That is, the upper case 23 and the lower case 25 have a center line 45 sandwiched between them, a U-shaped ridge 41 is continuously formed on one side, and a U-shaped groove 43 is continuously formed on the other side. ing.

  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. From this, the storage case 100 in which the compartment 27 that can be opened / closed by the ridge 41 and the groove 43 is formed by using one type of case formed by one mold.

FIG. 14 is an enlarged view of a main part showing a knob piece projecting from the chamfered portion of the storage case flange, and FIG. 15 is a perspective view of a main part showing the mutual positional relationship between the upper and lower case knobs engaged. It is.
The storage case 100 storing the cartridges 21 or the cartridge groups 29 one by one may be 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. Thereby, the 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.

  A knob 51 is extended on the periphery of each of the upper case 23 and the lower case 25, that is, on the flange 31. In the present embodiment, the upper case 23 and the lower case 25 are formed in a rectangular outer shape having four corners on the periphery. A chamfered portion 49 is formed at at least one corner of the upper case 23 and the lower case 25 by cutting off the corner with an inclined side. Further, the knob 51 is formed inside a quadrangular region enveloping the four sides of the outer shape of the upper case 23 and the lower case 25. If the knob 51 is extended to the chamfered portion 49, the knob 51 does not protrude from the rectangular case outer shape. For example, the case is accommodated in a cardboard box having the same inner shape as the outer case shape. However, the knob 51 does not interfere with storage.

  In the storage case 100, for the upper case 23 and the lower case 25 that are integrally formed by mutually engaging the ridges 41 and the concave grooves 43, the knobs 51 and 51 provided on the periphery of each case are picked. Thus, an opening force in the separating direction can be easily applied. In other words, when there is no knob 51, the cases can be reliably engaged with each other with a large engagement force that is difficult to release.

  In this embodiment, chamfered portions 49 are formed at four corners. In the present embodiment, the knob 51 is provided on a pair of chamfered portions 49 and 49 that sandwich the center line 45 shown in FIG. 2A. The knobs 51 and 51 are arranged eccentric from the center of the inclined side of the chamfered portion 49. That is, as shown in FIG. 14, the chamfered portion 49 is shifted from the center to one side. For example, in the case of the upper case 23 shown in FIG. 2A, the knob 51 that extends to the upper left chamfer 49 is eccentric from the center of the inclined side diagonally to the lower left and extends to the lower left chamfer 49. The piece 51 is eccentric from the center of the inclined side diagonally downward to the right.

  As shown in FIG. 1, when the upper case 23 and the lower case 25 having the same structure formed by the same mold form the compartment 27 and are stacked in the vertical direction, the knob 51 is as shown in FIG. In addition, they are not completely overlapped with each other and are arranged in a state of being shifted along the inclined side. Thereby, the engagement between the upper case 23 and the lower case 25 is easily released by separating both the knobs 51 from the upside down direction.

  FIG. 16 is an enlarged cross-sectional view showing the shapes of the concave and convex portions of the upper case 23 and the lower case 25. As described above, the convex strip 41 and the concave groove 43 can be configured to engage with a higher engagement force by providing the knob 51 and compared with the case where the knob 51 is not provided. Specifically, the opening width W <b> 1 of the groove 43 can be formed slightly smaller than the width W of the ridge 41. Further, the protrusion 41 may have a taper shape with a wide protruding tip width W and a slightly small proximal width W2. In this case, the groove 65 is a tapered groove having a groove bottom width W3 equal to the protruding tip width W of the ridge 41. By forming the ridges 41 and the concave grooves 43 with such a slight taper shape, a high engagement force can be applied while ensuring high sealing performance.

  Further, a step-bending portion 81 having a slightly bent periphery is formed on the outermost periphery of the upper case 23 and the lower case 25. Similar to the ridges 41 and the concave grooves 43, the step bent portions 81 are 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 step bending portion 81 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 storage case 100 is stacked in the vertical direction, the rectangular frame portions 53a and 53b on the lower surface of the upper storage case 100 are fitted into the square frame portions 53b and 53a on the upper surface of the lower storage case 100, so that the relative Is prevented from collapsing during stacking.

  Each of the upper case 23 and the lower case 25 is made of an integrally molded product of thermoplastic resin. For this reason, the upper case 23 and the lower case 25 having a robustness that reliably protects the cartridge by using a material that is flexible and relatively easy to handle, and an appropriate shock absorption property can be easily and Mass production is possible at low cost. In this example, a polystyrene resin having an impact strength of 8 J was used.

  Moreover, it is preferable that a thermoplastic resin is what has translucency. Thereby, even when the upper case 23 and the lower case 25 are engaged, the partition portion 47 is formed, and the partition chamber 27 becomes a closed independent space, the cartridge 21 accommodated in the partition chamber 27 is externally It becomes more visible, and the cartridge storage status in the compartment 27 can be easily grasped.

  Moreover, the minimum structural strength of the compartment which accommodates several cartridge groups is economically formed by extending | stretching (vacuum molding) using the sheet | seat of the thermoplastic resin of thickness 0.5mm-2.0mm. 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 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 the present embodiment, an optimal shock absorbing portion (crushable zone) can be formed by setting the sheet thickness of the thermoplastic resin within the above thickness range.

  According to the cartridge storage case 100 described above, the upper case 23 and the lower case 25, which are integrally formed by mutually engaging the protrusions 41 and the groove 43, are provided with the knobs 51 provided on the respective peripheral edges. By picking it, a separation force can be applied, and even when the engagement is hard, the engagement between the ridge 41 and the groove 43 is released and the storage case 100 is easily opened only when it is desired to open. Will be able to. In other words, the storage cases can be reliably engaged with each other with an engaging force that is difficult to release when there is no knob 51.

  In the cartridge storage case of the present invention, as shown in FIGS. 1 to 4, a plurality of compartments 27 formed inside by overlapping the upper case 23 and the lower case 25 from above and below are divided by partition portions 47. The room is divided into separate rooms. For this reason, even when dust enters one of the plurality of compartments, it does not enter the other compartments, and the dust can be prevented from spreading throughout the storage case. Further, since the partition portion 47 exists between the compartments, even if an impact is applied to each cartridge due to, for example, dropping, the partition portion is deformed to absorb the impact and impact the cartridge. It is not affected by force.

  The cartridge storage case of the present invention can stably hold and store any number of cartridges consisting of one or two round cartridges, or a cartridge group consisting of a plurality of cartridges. In addition to improving the convenience, even when the cartridge is lightly press-fitted into the case, scratches other than the ridge line portion of the cartridge are hardly scratched, and the impact resistance is excellent.

  As mentioned above, although one embodiment of the cartridge storage case of the present invention has been described in detail, the present invention is not limited to the above embodiment, and various modifications may be made without departing from the gist of the present invention.

  The cartridge storage case of the present invention can stably hold and store any number of cartridges consisting of a single volume, a double volume cartridge, etc., and a cartridge group consisting of a plurality of volume cartridges, and can handle orders that generate fractions. In addition, when the cartridge is lightly pressed into the case, it is difficult to scratch other than the ridge line of the cartridge, and the convenience has been greatly improved. For example, as a storage case for collecting and packaging one-reel type magnetic recording tape cartridges Preferably used.
