Description

  The present invention relates to a packing material for packing a tape cartridge.

  A tape cartridge that is used by being mounted on a printing apparatus is known (for example, see Patent Document 1). This tape cartridge includes a connecting arm. A print-receiving tape roll around which the print-receiving tape is wound is rotatably supported on one side of the connecting arm. On the other side of the connecting arm, a winding core (peeling material core) around which the release material layer peeled off from the print-receiving tape at the time of mounting is wound is rotatably supported.

JP2013-233661A

  In the above-described prior art tape cartridge, the release material core without the tape roll is disposed on the other side of the connecting arm, whereas the print-receiving tape roll is provided on the one side of the connecting arm. Be placed. Therefore, in the tape cartridge, the one side of the connecting arm (printed tape roll side) is heavier than the other side (the release material core side) of the connecting arm.

  When packing and transporting such a tape cartridge using a box, for example, during the transportation, the one side (printed tape roll side) of the connecting arm is on the upper side, and the other side of the connecting arm (for the release material) There is a case where the posture (winding core side) is on the lower side (hereinafter, referred to as “vertical posture” as appropriate). In such a vertically placed posture, for example, when a large impact is applied in the vertical direction due to inadequate handling or dropping during cargo handling work, if the rigidity of the box body containing the print-receiving tape roll is relatively large Then, the connecting arm bends due to the large load of the print-receiving tape roll located above, and the print-receiving tape roll comes into contact with the release material core and the surrounding structure, and the large load from the print-receiving tape roll acts. The soundness of the tape cartridge may be reduced.

  In the prior art described above, no particular consideration has been given to the possibility of a decrease in soundness during transportation of the tape cartridge as described above.

  An object of the present invention is to provide a packaging material capable of improving soundness during transportation of a tape cartridge.

In order to achieve the above object, the present invention provides a first roll holding portion forming a tape roll around which a predetermined amount of tape is wound, and an axis in the first direction. A second roll holding portion that does not form the tape roll, and rotatably supports the first roll holding portion on one side of the second direction orthogonal to the first direction, and in the second direction. A connecting arm that rotatably supports the second roll holding part on the other side, and a first protruding part that protrudes on both sides along the first direction on the one side in the second direction of the connecting arm. And a second projecting portion projecting on both sides along the first direction on the other side in the second direction of the connecting arm. Two sides The first roll holding part is accommodated when the tape cartridge is packed, and the first direction and the second are provided on both sides of the first roll holding part along the first direction. Two first side wall portions respectively erected in a third direction orthogonal to the direction, and the first projecting portion is locked when the first roll holding portion is provided in each of the two first side wall portions. A first box part having a substantially box shape, and a second box-shaped first box part that supports left and right side pieces of the connection arm, and provided on the other side in the second direction. Two second side walls that house the second roll holding portion during packaging of the tape cartridge and that stand upright in the third direction on both sides of the second roll holding portion along the first direction. And the two second side wall portions A second box part having a substantially box-like shape, and a second box part that holds the second protrusion when the second roll holding part is stored. The wall of the side wall is thicker than the wall of the second side wall.

  The packing material of the present invention is used for packing a tape cartridge and transporting the tape cartridge. The tape cartridge includes a connecting arm, a first roll holding unit, and a second roll holding unit.

  The first roll holding part is rotatably supported on one side (for example, the rear side) in the second direction (for example, the front-rear direction) of the connecting arm, and is mounted on the substantially box-shaped first box part when packing the tape cartridge. Stored. The first box portion includes a first side wall portion standing on both sides of the first roll holding portion along a first direction (for example, the left-right direction), and a first locking portion provided on each first side wall portion. I have. When the first roll holding part is stored in the first box body part, the first projecting part projecting to both sides in the first direction on the one side in the second direction of the connecting arm is latched by the first latching part. . Thereby, the one side part of the 2nd direction of a tape cartridge is stably supported by the 1st box part.

  The second roll holding portion is rotatably supported on the other side (for example, the front side) of the connecting arm in the second direction (for example, the front-rear direction). When the tape cartridge is packed, the second roll holding portion is attached to the substantially box-shaped second box portion. Stored. The second box portion includes a second side wall portion standing on both sides of the second roll holding portion along a first direction (for example, the left-right direction), and a second locking portion provided on each second side wall portion. I have. When the second roll holding part is housed in the second box body part, the second projecting part projecting to both sides in the first direction on the other side (for example, the front side) of the connecting arm in the second direction is the second locking part. Locked. Thereby, the second direction other side portion of the tape cartridge is stably supported by the second box body portion.

  Here, the second roll holding part on which the tape roll is not formed is arranged on the other side in the second direction of the connecting arm, whereas the tape roll is formed on the one side in the second direction of the connecting arm. A first roll holder is disposed. Therefore, the tape cartridge is heavier on the one side in the second direction of the connecting arm (first roll holding part side) than on the other side in the second direction of the connecting arm (second roll holding part side).

  As described above, the packaging material of the present invention is used, for example, when the tape cartridge is transported. In this case, for example, in the middle of transportation, the posture in which the second direction one side (first roll holding part side) of the connecting arm is on the upper side and the second direction other side (second roll holding part side) of the connecting arm is on the lower side. (Hereinafter referred to as “vertical posture” as appropriate). In such a vertically placed posture, for example, when a large impact is applied in the vertical direction due to inadequate handling or dropping during cargo handling work, the rigidity of the second box body portion containing the second roll holding portion is compared. If it is large, the connecting arm is bent due to the large load of the first roll holding portion located above, the first roll holding portion comes into contact with the second roll holding portion, and the large load from the first roll holding portion is There is a possibility that the soundness of the tape cartridge may be lowered by acting on the two-roll holding unit.

  Therefore, in the present invention, the thickness of the first side wall portion is made thicker than the wall thickness of the second side wall portion, thereby relatively increasing the rigidity of the first box portion (in other words, the second box portion). The rigidity of the body part is relatively small). As a result, even if a large impact is applied in the vertical direction in the above-described vertical position, the impact can be absorbed by preferentially breaking the second box portion that houses the second roll holding portion. As a result, the contact of the first roll holding part to the second roll holding part due to the occurrence of the bending of the connecting arm is suppressed, and the action of a heavy load on the second roll holding part is suppressed, thereby improving the soundness of the tape cartridge. Can be improved.

  According to the present invention, soundness during transportation of the tape cartridge can be improved.

The front opening / closing cover 9 can open and close above the third storage portion 4 by rotating around a predetermined rotation axis K3 provided at the upper end of the front side of the housing body 2a. Specifically, the front opening / closing cover 9 is opened from the closed position (the state shown in FIGS. 1 and 2) covering the upper side of the third storage unit 4 to the upper side of the third storage unit 4 (the state shown in FIG. 3). ). At this time, as shown in FIGS. 2 and 3, the tape cartridge TK (see FIG. 2) is attached to and detached from the first predetermined position 13 below the front opening / closing cover 9 in the closed state in the housing body 2a. Installed as possible.

<Schematic configuration of tape cartridge>
As shown in FIG. 4, the tape cartridge TK includes a first roll holding unit 50 having a print-receiving tape roll R1 (corresponding to a tape roll) around which the print-receiving tape 150 is wound, and the tape cartridge TK is not used. And a connecting arm 16 that connects the first roll holding part 50 and the second roll holding part 60 to each other.

<First roll holding unit>
The first roll holding unit 50 includes a winding core (not shown) having an axis O1 in the left-right direction (corresponding to the first direction), and substantially circular flanges f1 and f2 each having a hole shape fixed to both left and right ends of the winding core. And. When the tape cartridge TK is in a new unused state, a predetermined amount of the print-receiving tape 150 is wound around the winding core, thereby forming the print-receiving tape roll R1.

  The connecting arm 16 includes a pair of left and right first bracket portions 20 and 20 provided on the rear side, and a pair of left and right second bracket portions 21 and 21 provided on the front side (corresponding to the other side in the second direction). I have. The first bracket portions 20 are connected to each other while avoiding interference with the outer diameter of the print-receiving tape roll R1 by a first connection portion 22 extending substantially along the left-right direction at the upper end portion. The 2nd bracket parts 21 and 21 are connected by the 2nd connection part 23 extended substantially along the left-right direction in the upper end part. The first bracket parts 20 and 20 and the first connection part 22 on the rear side and the second bracket parts 21 and 21 and the second connection part 23 on the front side are connected by a pair of left and right connection beam parts 24 and 24. Has been.

  Each first bracket portion 20 has a substantially oval frame-shaped (oval-type) first protrusion 104 that protrudes outward in the left-right direction in the vicinity of the lower end. Each first protrusion 104 is fitted with a shaft support portion having a fixed shaft portion (not shown) that protrudes inward in the left-right direction, and the shaft support portion is fixed to each first bracket portion 20. Each fixed shaft portion is loosely fitted in the hole portion of the winding core, and the fixed shaft portions are connected to each other in the hole portion. Thus, the winding core and flange f1 (with the print-receiving tape roll R1 formed) between the pair of left and right first bracket portions 20 and 20 in a state where the tape cartridge TK is mounted on the housing body 2a. , F2 are integrally held so as to be rotatable around the axis O1.

  By mounting the tape cartridge TK, the first roll holder 50 is received from above in the first storage unit 3 and stored in a state where the axis O1 of the core of the print-receiving tape roll R1 is in the left-right direction. Then, in a state where the first roll holding unit 50 is stored in the first storage unit 3 (in a state where the tape cartridge TK is mounted), the winding core and the flanges f1 and f2 rotate within a predetermined rotation in the first storage unit 3. By rotating in the direction (A direction in FIG. 2), the print-receiving tape 150 is fed out from the print-receiving tape roll R1.

  In this example, the case where the print-receiving tape 150 having adhesiveness is used is illustrated. That is, the print-receiving tape 150 includes a print-receiving layer 154, a base material layer 153, an adhesive layer 152, and a release material layer 151 from one side in the thickness direction (upper side in FIG. 2) to the other side (in FIG. 2). The lower layers are stacked in this order. The print target layer 154 is a layer in which a desired print portion 155 (see a partially enlarged view in FIG. 2) is formed by thermal transfer of ink by the print head 11. The pressure-sensitive adhesive layer 152 is a layer for attaching the base material layer 153 to an appropriate adherend (not shown). The release material layer 151 is a layer that covers the pressure-sensitive adhesive layer 152.

<Second roll holding unit>
The second roll holding unit 60 includes a winding core 29 having a horizontal axis O2 and substantially circular flanges f3 and f4 each having a hole shape fixed to both left and right ends of the winding core 29. As will be described later, the winding core 29 is used to wind up the release material layer 151 separated after printing on the print-receiving tape 150. When the tape cartridge TK is not used, the winding core 29 includes a release material. The release material roll R2 around which the layer 151 is wound is not formed. However, in FIG. 4, the sign “R2” is attached to the portion where the release material roll R2 is formed for convenience (in order to make the comparison with FIG. 2 and the like easier to understand).

  Each second bracket portion 21 has a substantially circular frame-like second protrusion 109 protruding outward in the left-right direction in the vicinity of the lower end. A shaft support portion having a fixed shaft portion (not shown) protruding inward in the left-right direction is fitted to each second protrusion portion 109, and the shaft support portion is fixed to each second bracket portion 21. Each fixed shaft portion is loosely fitted in the hole portion of the core 29 of the second roll holding portion 60, and the fixed shaft portions are connected to each other in the hole portion. Thus, the winding core 29 and the flanges f3 and f4 are integrated between the pair of left and right second bracket portions 21 and 21 in a state where the tape cartridge TK is mounted on the housing body 2a, and the axis O2 is surrounded. Is held rotatably.

  In the second storage unit 5 shown in FIG. 2, the second roll holding unit 60 is received from above by the mounting of the tape cartridge TK described above, and the axis O2 of the winding core 29 is left and right. It is stored in the direction. Then, in a state where the second roll holding unit 60 is stored in the second storage unit 5 (a state where the tape cartridge TK is mounted), a gear mechanism is provided by a release paper winding motor M3 provided in the housing body 2a. It is driven via (not shown). As a result, the core 29 and the flanges f3 and f4 are rotated in a predetermined rotation direction (C direction in FIG. 2) in the second storage unit 5 and thus peeled off from the printed tape 150 ′. The release material layer 151 is wound around the core 29 to form the release agent roll R2.

The transport roller 12 is driven from a first roll R1 stored in the first storage unit 3 by being driven through a gear mechanism (not shown) by a transport motor M1 provided inside the housing body 2a. The printed tape 150 to be printed is conveyed in a tape posture in which the tape width direction is the left-right direction.

  In addition, the print head 11 is provided in the head holding portion 10 provided in the first opening / closing cover 8a. As described above, the print head 11 can be relatively separated from and brought close to the transport roller 12 by the first opening / closing cover 8a rotating about the rotation axis K1. That is, when the first opening / closing cover 8a is in the closed state, the print head 11 comes close to the conveying roller 12, and when the first opening / closing cover 8a is in the opened state, the printing head 11 is separated from the conveying roller 12. The print head 11 includes a transport roller in the first opening / closing cover 8a in the closed state of the head holding unit 10 so as to sandwich the print-receiving tape 150 transported by the transport roller 12 in cooperation with the transport roller 12. 12 is disposed at a position facing above 12. Therefore, when the first opening / closing cover 8a is in the closed state, the print head 11 and the transport roller 12 are arranged to face each other in the vertical direction. The print head 11 forms a desired print on the print target layer 154 of the print target tape 150 sandwiched between the conveyance rollers 12 by using an ink ribbon IB of an ink ribbon cartridge RK described later. Thus, the printed tape 150 ′ is obtained.

<Ink ribbon cartridge>

In the ink ribbon cartridge RK, the feeding roll storage part 81 on the rear side and the winding roll storage part 82 on the front side are connected by a central connection part (not shown). The connecting portion connects the take-up roll storage portion 82 and the supply roll storage portion 81 while exposing the ink ribbon IB fed from the ribbon feed roll R4 to the outside of the ink ribbon cartridge RK.

  The ribbon feeding roll R4 is rotatably supported in the feeding roll storage unit 81, and rotates in a predetermined rotation direction (D direction in FIG. 2) when the ink ribbon cartridge RK is mounted. The ink ribbon IB for performing print formation by the head 11 is fed out.

  The ribbon take-up roll R5 is rotatably supported in the take-up roll storage unit 82, and rotates in a predetermined rotation direction (E direction in FIG. 2) with the ink ribbon cartridge RK mounted. Then, the used ink ribbon IB after the printing is formed is wound up.

  That is, in FIG. 2, the ink ribbon IB fed out from the ribbon feeding roll R4 is further arranged on the print head 11 side of the print-receiving tape 150 in a state of being sandwiched between the print head 11 and the conveying roller 12, and the print head. 11 below. Then, after the ink from the ink ribbon IB is transferred to the print layer 154 of the print-receiving tape 150 by the heating from the print head 11 and the print formation is executed, the used ink ribbon IB is transferred to the ribbon take-up roll R5. Rolled up.

<Around the second roll holder>
As shown in FIG. 4, the connecting arm 16 of the tape cartridge TK includes a peeling portion 17 including, for example, a substantially horizontal slit shape. The peeling portion 17 is a portion where the release material layer 151 is peeled off from the printed tape 150 ′ that is fed out from the print-receiving tape roll R 1 and conveyed forward. As shown in FIG. 2, the printed tape 150 ′ on which the printing has been formed as described above is peeled off by the peeling portion 17 to peel off the peeling material layer 151 and the other parts. The printed layer 154, the base material layer 153, and the pressure-sensitive adhesive layer 152 are separated into a printed tape 150 ″.

  As described above, the release material layer 151 peeled off from the printed tape 150 ′ is wound around the core 29 of the second roll holding unit 60 in the second storage unit 5, whereby the release agent roll R 2 is wound. It is formed.

<Printed tape roll and its surroundings>

The notches 126 and the ends of the cut lines 119 (corresponding to the drawing positions of the lead lines “126” and “119” in the figure) are the lower ends of the engaging grooves 80 (the locking grooves 91 described above). This corresponds to the portion where the upper end of the abuts.

<Folding>
When the box body 71 is created from the cardboard paper 100, the following parts are folded.

<Folding on the first to third regions>
That is, first, by folding the two third regions 113, 113 along a valley fold line h3 between the fourth regions 114 (see white arrows), the left and right outer wall portions 73, 73 and A bottom wall 72 therebetween is formed (see FIG. 8). Thereafter, each of the two second regions 112, 112 is valley-folded along a valley fold line h2 between the corresponding third regions 113 (see the white arrows), whereby the left and right upper wall portions 74, 74 is formed (see FIG. 8).

  Then, each of the two first regions 111, 111 is valley-folded along a valley fold line h1 between the corresponding second regions 112 (see the white arrow), whereby the left and right inner wall portions 75, 75 (in other words, left and right reinforcing wall portions 83, 83 and left and right front wall portions 82, 82) are formed. As described above, the outer wall portions 73 and 73, the upper wall portions 74 and 74, and the inner wall portions 75 and 75 can be assembled on the left and right sides of the bottom wall portion 72 in a U-shaped cross section.

<Folding on the fifth and sixth regions>
On the other hand, substantially in parallel with (or prior to) the assembly of the U-shaped cross section, valley folding is performed at the valley folding line h5 between the fourth region 114 and the sixth region 116 (see the white arrow), and By performing valley folds at the valley fold lines h4 and h4 between the sixth region 116 and the fifth regions 115 and 115 (white arrows), the left and right rear side wall portions 76 and 76 (in other words, the left and right rear wall portions 81). 81) and the rear side wall 77.

<Overall folding assembly>
The back side wall 76 is inserted from the right in the figure between the inner wall 75 and the outer wall 73 assembled in a U-shaped cross section as described above, and the back side 76 is connected to the back of the inner wall 75. Position on the side. Thereafter, the holding piece 79 of each outer wall portion 73 is bent, and the protruding piece 79 a of the holding piece 79 is locked to the locking groove 76 a of the back side wall portion 76. As a result, the direction of the eye of one of the rear wall 81 and the reinforcing wall 83 of the first box 71A (in this example, the reinforcing wall 83) is the vertical direction, and the rear wall 81 and It arrange | positions so that the direction of the said eyes of the other (in this example, back wall part 81) among the reinforcement wall parts 83 may turn into the front-back direction.

  The box body 71 is created by the above assembly. Note that the order of assembly described above is an example, and is not limited to this, and can be changed as appropriate.

<Effect of this embodiment>
As described above, the packing material 70 of the present embodiment is used for packing the tape cartridge TK and transporting the tape cartridge TK.

  The first roll holding unit 50 is housed in a substantially box-shaped first box part 71A when the tape cartridge TK is packed. When the first roll holding part 50 is housed in the first box part 71A, the first protrusions 104 that protrude to the left and right sides on the rear side of the connecting arm 16 are locked to the first locking part 81a. Thereby, the rear side portion of the tape cartridge TK is stably supported by the first box body portion 71A.

  The second roll holding part 60 is accommodated in a substantially box-shaped second box part 71B when the tape cartridge TK is packed. When the second roll holding part 60 is stored in the second box part 71B, the second protruding part 109 protruding to the left and right sides on the front side of the connecting arm 16 is locked to the second locking part 82a. Thereby, the front side portion of the tape cartridge TK is stably supported by the second box portion 71B.

  Here, in the second roll holding portion 60 on the front side of the connecting arm 16 (in the unused state), the release material roll R2 is not yet formed, whereas the first roll holding on the rear side of the connecting arm 16 is performed. In part 50, a print-receiving tape roll R1 is formed. Therefore, the tape cartridge TK is heavier on the rear side (first roll holding unit 50 side) than on the front side (second roll holding unit 60 side).

  In the present embodiment, corresponding to the above, the wall thickness of the first side wall portions 81 and 83 is made thicker than the wall thickness of the front wall portion 82 as the second side wall portion. Thus, when the tape cartridge TK is packed, the rigidity of the first side walls 81 and 83 on the side that supports a large load in a weight balance can be reinforced, and the first locking to which a particularly large load is applied. The rigidity of the locking part of the 1st protrusion part 104 by the part 81a can be reinforced reliably. As a result, the durability of the entire packaging material 70 as a box can be improved.

  On the other hand, as described above, the packaging material of the present embodiment is used, for example, when the tape cartridge TK is transported. In this case, for example, in the middle of transportation, the vertical posture with the rear side (first roll holding unit 50 side) of the connecting arm 16 on the upper side and the front side (second roll holding unit 60 side) of the connecting arm 16 on the lower side. It may become. In such a vertically placed posture, when a large impact is applied in the vertical direction due to, for example, inadequate handling or dropping during cargo handling work, the soundness of the tape cartridge TK may be reduced. Such a case will be described with reference to a comparative example shown in FIG.

<Comparative example>
Fig.10 (a) is sectional drawing which shows typically the box of the packing material in the said comparative example. In the figure, in the box body 71 ′ in the packaging material 70 ′ of this comparative example, the second box body 71 B ′ is configured to have a relatively large rigidity like the first box body 71 A ′. The box 71 ′ is in a vertically placed posture with the first roll holding part 50 on the rear side of the connecting arm 16 of the tape cartridge TK on the upper side and the second roll holding part 60 on the front side of the connecting arm 16 on the lower side. Is located.

  In such a vertically placed posture, if the box body 71 'falls (see the white arrow) and a large impact is applied in the vertical direction as shown in FIG. The force is transmitted to the tape cartridge TK. In this case, in the box body 71 ′, since the rigidity of the second box body portion 72A ′ housing the second roll holding portion 60 is relatively large as described above, the impact force applied to the box body 71 ′ is reduced. It cannot be transmitted to the tape cartridge TK while absorbing and relaxing) and is transmitted to the tape cartridge TK with a large impact force. As a result, the connecting arm 16 bends due to the large load of the first roll holding unit 50 positioned above, and the first roll holding unit 50 comes into contact with the second roll holding unit 60 (see the white arrow), and the first roll A large load from the holding unit 50 may act on the second roll holding unit 60, and the soundness of the tape cartridge TK may be reduced.

<Soundness improvement effect by embodiment>
Therefore, in the present embodiment, the wall thickness of the first side wall portions 81 and 83 is set to the thickness of the wall of the front wall portion 82 as the second side wall portion (by providing the reinforcing wall portion 83 in the above example). Thicker than that. As a result, the rigidity of the first box part 71A is relatively large (in other words, the rigidity of the second box part 71B is relatively small). As a result, even when a large impact is applied in the vertical direction in the above-described vertical orientation, the second box portion 71B that houses the second roll holding portion 60 is preferentially destroyed to absorb the impact. it can. In addition, it is not restricted to the method of increasing the thickness of the wall of the said 1st side wall part 81 and 83 by including the reinforcement wall part 83 as mentioned above, When the back wall part 81 is comprised with one wall, the A method of making the thickness of the material itself thicker than the thickness of the material constituting the front wall portion 82 may be used. In this case, the rear wall portion 81 corresponds to the first side wall portion described in each claim. The above effect will be specifically described with reference to FIG.

  Fig.11 (a) is sectional drawing which shows typically the box 71 of the packing material 70 in this embodiment. In the box body 71 in the packing material 70 of the present embodiment, as described above, the second box body portion 71B is formed to have a rigidity smaller than that of the first box body portion 71A (in the drawing, convenience is indicated by fine hatching lines). Expressively). As in the comparative example, the box body 71 has the first roll holding part 50 on the rear side of the connecting arm 16 of the tape cartridge TK on the upper side and the second roll holding part 60 on the front side of the connecting arm 16 on the lower side. Located in a vertical position.

  In such a vertical position, the second roll is held even if a large impact is applied to the box 71 in the vertical direction (see the white arrow) as shown in FIG. Since the rigidity of the second box part 71B housing the part 60 is relatively small, the second box part 71B is preferentially deformed and destroyed. For this reason, the impact force applied to the box 71 can be absorbed, and the impact force transmitted to the tape cartridge TK can be reduced. As a result, unlike the comparative example, the stress concentration on the connecting arm 16 is suppressed, and the contact of the first roll holding part 50 with the second roll holding part 60 due to the occurrence of the bending is suppressed, and the second roll holding It is possible to improve the soundness of the tape cartridge TK by suppressing the action of a large load on the portion 60.

  In addition, at this time, in the above-described storage support state, the gap between the first protrusion 104 of the tape cartridge TK and its peripheral portion and the first locking portion 81a of the first box portion 71A and the storage hole 84 is as follows. The tape cartridge TK is substantially in close contact with the second protrusion 109 and its peripheral portion and the second locking portion 82a and the receiving hole 85 of the second box portion 71B to some extent. The gap is provided. Thereby, the said impact force can be released by the said clearance gap in the said 2nd box part 71B at the time of the fall generation | occurrence | production in said vertical installation attitude | position. Also by this, the stress concentration on the connecting arm 16 is suppressed, the contact of the first roll holding part 50 with the second roll holding part 60 due to the occurrence of bending is suppressed, and the soundness of the tape cartridge TK can be improved. There is.

  In the present embodiment, in particular, the first box part 71 </ b> A located on the rear side includes the reinforcing wall part 83. Furthermore, each reinforcing wall 83 is provided with a reinforcing locking portion 83a that can reinforce the locking state of the first protrusion 104 by the first locking portion 81a. Thereby, the rigidity of the locking part of the 1st protrusion part 104 by the said 1st locking part 81a can be reinforced reliably. Further, even if the first protrusion 104 is locked to the first locking part 81a, the first protrusion 104 can be received by the reinforcing locking part 83a located inward in the left-right direction. As a result, damage due to dropping of the tape cartridge TK can be suppressed.

  In this embodiment, in particular, a partition plate 90 is provided so as to partition the first box part 71A and the second box part 71B. As a result, even when a large impact is applied in the vertical direction in the above-described vertical posture and the first roll holding unit 50 approaches the second roll holding unit 60, as shown in FIG. Can be interposed between the first roll holding part 50 and the second roll holding part 60. As a result, it is possible to further reliably suppress a large load from acting on the second roll holding unit 60 as described above.

  In the present embodiment, in particular, the partition plate 90 is provided with a locking groove 91, and the locking groove 91 is locked to the first side wall portions 81 and 83 (or the front wall portion 82). And the deformation | transformation to the left-right direction of the said side wall parts 81 and 82 can be suppressed. Thereby, the durability as the box of the whole packing material 70 can further be improved.

  In the present embodiment, in particular, the eye direction of one of the rear wall part 81 and the reinforcing wall part 83 of the first box part 71A (the reinforcing wall part 83 in the above example) is the vertical direction, Of the rear wall portion 81 and the reinforcing wall portion 83, the other eye (the rear wall portion 81 in the above example) is arranged so that the eye direction is the front-rear direction.

  As a result, when the vehicle is dropped along the front-rear direction in the vertical posture (see FIG. 10 and the like), the portion with the eyes in the front-rear direction (the rear wall portion 81 in the above example) Damage to the one box body 71A can be suppressed. When the connecting arm 16 of the tape cartridge TK is horizontally placed and dropped along the up-and-down direction, the portion having the eyes in the up-and-down direction (the reinforcing wall portion 83 in the above example) The strong rigidity can suppress damage to the first box body 71A.

  Although the present embodiment has been described above, the methods according to the above embodiments may be appropriately combined and used in addition to those already described.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
