[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-208785 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, efforts to store printing cassettes in storage boxes without using packaging bags have been considered in light of the Sustainable Development Goals (SDGs). However, paper dust can be generated when the printing cassette rubs against the wall of the storage box. When a printing cassette with paper dust attached is installed in a printing device, the paper dust can affect the print results.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a printing cassette storage unit in which the printing cassette and the storage box are less likely to rub against each other. [Means for solving the problem]

[0006] According to a first aspect of the present invention, there is provided a printing cassette storage unit including a printing cassette and a storage box for storing the printing cassette, the storage box being formed by bending a portion of the storage box and including a pressing portion that contacts the printing cassette and presses the printing cassette against the inner surface of the storage box. The pressing portion presses the printing cassette against the inner surface of the storage box. Thus, by eliminating a gap between the printing cassette and the storage box, the printing cassette storage unit reduces friction between the storage box and the printing cassette due to vibrations during transportation, etc., and suppresses the generation of paper dust. Furthermore, because the pressing portion is part of the storage box and not a separate part, the production costs of the storage box can be reduced.

[0007] In a first aspect, the printing cassette may contain tape used for printing by a printing device, and the pressing portion may contact an unexposed surface of the outer surface of the printing cassette that is different from an exposed surface on which the tape is exposed, thereby pressing the printing cassette against the inner surface of the storage box. The pressing portion does not contact the exposed surface, and therefore does not contact the tape. Therefore, the printing cassette storage unit can prevent damage to the tape due to vibrations during transportation, etc.

[0008] In a first aspect, the printing cassette may contain a tape used for printing by a printing device, and the pressing unit may press an unexposed surface of the outer surface of the printing cassette, which is different from an exposed surface on which the tape is exposed, against the inner surface of the storage box. The pressing unit presses the unexposed surface of the printing cassette against the inner surface of the storage box. Thus, the printing cassette storage unit can prevent damage to the tape due to vibrations during transportation, etc.

[0009] In a first aspect, the pressing portion may have at least two of the following portions: a first pressing portion extending in a first direction in which a first inner surface, which is one of the inner surfaces of the storage box, and a second inner surface opposing the first inner surface oppose each other, and is disposed in a gap between the first inner surface and the printing cassette, and pressing the printing cassette against the second inner surface in the first direction; a second pressing portion extending in a second direction in which a third inner surface different from the first inner surface and the second inner surface opposes a fourth inner surface opposing the third inner surface, and is disposed in a gap between the third inner surface and the printing cassette, and pressing the printing cassette against the fourth inner surface in the second direction; and a third pressing portion extending in a third direction in which a fifth inner surface different from the first inner surface, the second inner surface, the third inner surface, and the fourth inner surface opposes a sixth inner surface opposing the fifth inner surface, and is disposed in a gap between the fifth inner surface and the printing cassette, and pressing the printing cassette against the sixth inner surface in the third direction. The pressing section presses the printing cassette against the inner surface of the storage box in two or more directions, making it difficult for the storage box and the printing cassette to rub against each other due to vibrations during transportation, etc., and suppressing the generation of paper dust.

[0010] In the first aspect, the pressing portion may be formed by folding a flap connected to the edge of the storage box. The pressing portion is formed by folding the flap of the storage box. Compared to forming a U-shaped cutout on the outer surface of the storage box and folding it back inward, this eliminates the need to form holes or the like in the storage box. Furthermore, by further folding the portion of the flap that abuts against the printing cassette and bringing it into face contact with the printing cassette, the printing cassette can be pressed more reliably.

[0011] In the first aspect, the pressing portion may be formed by folding a cut portion formed in a part of the outer surface of the storage box toward the inside of the storage box. By forming the pressing portion by folding a cut portion formed in the outer surface of the storage box toward the inside of the storage box, the unfolded area of ​​the sheet before assembling the storage box can be smaller than when the pressing portion is formed with a flap, thereby reducing the production cost of the storage box.

[0012] In the first aspect, the pressing portion may be formed in two or more locations on one outer surface of the storage box. If the pressing portion is formed in only one location on one outer surface of the storage box, the printing cassette may tilt inside the storage box with the portion that abuts against the pressing portion as a fulcrum due to vibrations during transport, etc. By forming the pressing portions in two or more locations on one outer surface, the pressing portion can press the printing cassette against the inner surface of the storage box at two or more locations, making it possible to prevent the printing cassette from tilting inside the storage box.

[0013] According to a second aspect of the present invention, there is provided a printing cassette storage unit including a printing cassette, a storage box for storing the printing cassette, and an attachment member attached to the printing cassette, wherein the attachment member has a pressing portion that contacts a first inner surface of the storage box to press the printing cassette against a second inner surface of the storage box that faces the first inner surface. When the attachment member is attached to the printing cassette and stored in the storage box, the pressing portion is positioned in the gap between the printing cassette and the first inner surface. Thus, by eliminating the gap between the printing cassette and the storage box, the printing cassette storage unit is less likely to rub against the storage box and the printing cassette due to vibrations during transportation, etc., and can suppress the generation of paper dust. Furthermore, because the attachment member, with the pressing portion already assembled, is attached to the printing cassette and then stored in the storage box, assembly of the printing cassette storage unit is easier than when the pressing portion is formed by folding back a flap.

[0014] In a second aspect, the printing cassette may house a tape used for printing by a printing device and a spool around which the tape is wound, the mounting member may be mounted to the printing cassette by engaging with the spool, and the pressing portion may cover an exposed surface of the outer surface of the printing cassette on which the tape is exposed. The pressing portion covers the exposed surface of the printing cassette. Therefore, the tape exposed from the printing cassette does not come into contact with the inner surface of the storage box, and the printing cassette storage unit can prevent damage to the tape due to vibrations during transportation, etc.

[0015] In a second aspect, the printing cassette may house a tape used for printing by a printing device and a spool around which the tape is wound, the mounting member may be mounted to the printing cassette by engaging with the spool, and the pressing portion may press an unexposed surface of the outer surface of the printing cassette, which surface is different from an exposed surface on which the tape is exposed, against the second inner surface of the storage box. The pressing portion presses the unexposed surface of the printing cassette against the second inner surface of the storage box. Therefore, the tape exposed from the printing cassette is not pressed against the second inner surface of the storage box, and the printing cassette storage unit can prevent damage to the tape due to vibrations during transportation, etc.

[0016] In a second aspect, the pressing portion of the mounting member may have at least two of the following: a first pressing portion that comes into contact with the first inner surface of the storage box to press the printing cassette against the second inner surface; a second pressing portion that comes into contact with a third inner surface of the storage box that is different from the first and second inner surfaces to press the printing cassette against a fourth inner surface of the storage box that faces the third inner surface; and a third pressing portion that comes into contact with a fifth inner surface of the storage box that is different from the first, second, third, and fourth inner surfaces to press the printing cassette against a sixth inner surface of the storage box that faces the fifth inner surface. Because the pressing portion presses the printing cassette against the inner surface of the storage box in two or more directions, it is possible to reduce friction between the storage box and the printing cassette due to vibrations during transport, etc., and to suppress the generation of paper dust.

[0017] In a second aspect, the printing cassette may include at least one recess formed in a specific surface that is one of the outer surfaces, the mounting member may include at least one insertion piece formed in an opposing surface facing the specific surface and inserted into the at least one recess of the printing cassette, and the pressing portion may have a first connection surface that is connected to the opposing surface and formed on the same surface as the opposing surface and positioned at a position corresponding to the gap between the printing cassette and the first inner surface. By producing the mounting member from a single sheet, the first connection surface can be positioned in a position corresponding to the gap between the printing cassette and the first inner surface within the storage box simply by inserting the insertion piece into the recess of the printing cassette, without performing processing such as folding the sheet.

[0018] In a second aspect, the pressing portion may include a second connecting surface that is directly or indirectly connected to the first connecting surface and folded back to abut against the printing cassette or the first connecting surface. The second connecting surface that connects to the first connecting surface is folded back to abut against the printing cassette or the first connecting surface, so that the pressing portion is supported by the first connecting surface and the second connecting surface. This makes the pressing portion less likely to deform due to vibrations during transport, and the mounting member reduces friction between the storage box and the printing cassette, thereby suppressing the generation of paper dust.

[0019] In a second aspect, the pressing portion of the mounting member is a first pressing portion that contacts the first inner surface of the storage box to press the printing cassette against the second inner surface, and the storage box may include a fourth pressing portion that is formed by folding a portion of the storage box and contacts a fifth inner surface different from the first and second inner surfaces of the storage box to press the printing cassette against a sixth inner surface opposite the fifth inner surface. The first pressing portion contacts the first inner surface of the storage box to press the printing cassette against the second inner surface. The fourth pressing portion contacts the fifth inner surface of the storage box to press the printing cassette against the sixth inner surface. Thus, by eliminating gaps between the printing cassette and the storage box in two directions, the printing cassette storage unit is less likely to rub against the storage box and the printing cassette due to vibrations during transportation, etc., and can suppress the generation of paper dust. Furthermore, since the first pressing portion presses against the second inner surface and the fourth pressing portion presses against the sixth inner surface, the fourth pressing portion and the mounting member do not need to have complex shapes, making it easy to assemble the printing cassette storage body.

[0020] In a second aspect, the storage box includes a top wall and a bottom wall that extend intersecting with a vertical direction and are arranged side by side in the vertical direction, a front wall and a rear wall that extend intersecting with a front-rear direction orthogonal to the vertical direction and are arranged side by side in the front-rear direction, and a left wall and a right wall that extend intersecting with a left-right direction orthogonal to the vertical direction and the front-rear direction and are arranged side by side in the left-right direction, the fourth pressing portion is connected to an upper edge of the left wall or the right wall, and when the length of the storage box in the left-right direction is X1 and the length in the up-down direction is Y1, and the length of the printing cassette arranged inside the storage box in the left-right direction is X2 and the length in the up-down direction is Y2, if the relationship {X1 / a+(Y1-Y2)}>{Y1 / a+2×(X1-X2)} is satisfied, the length of the fourth pressing portion before bending is {Y1 / a+2×(X1-X2)}, and the fourth pressing portion is connected to an upper edge of the left wall or the right wall. and the first pressing portion is disposed between the top wall and the printing cassette, and extends to the right or left from the upper edge of the storage box, turns back downward, and turns back to the left or right at a position 1 / a with respect to the left-right side of the storage box to abut against the left wall or the right wall, and the first pressing portion is disposed between the top wall and the printing cassette, and when {X1 / a+(Y1-Y2)}≦{Y1 / a+2×(X1-X2)} is satisfied, The length of the pressing portion before folding may be {X1 / a+(Y1-Y2)}, the fourth pressing portion may be disposed between the top wall and the printing cassette so as to extend from the upper edge of the left or right wall toward the right or left and fold back downward at a position 1 / a relative to the vertical side of the storage box to abut against the printing cassette, and the first pressing portion may be disposed between the left or right wall and the printing cassette. Because the positions of the fourth pressing portion and the first pressing portion can be set according to the left-right and vertical lengths of the storage box and the printing cassette and the length of the fourth pressing portion can be made shorter, the printing cassette storage unit is easier to assemble.

[0021] In a second aspect, the fourth pressing portion has a contact portion with a length C at its tip portion, and when {X1 / a+(Y1-Y2)}>{Y1 / a+2×(X1-X2)} is satisfied, the length of the fourth pressing portion before folding is {Y1 / a+2×(X1-X2)}+C, and the fourth pressing portion extends from the upper edge of the left wall or the right wall in the right direction or the left direction, is folded back in the downward direction, is folded back in the left direction or the right direction at a position 1 / a with respect to the left-right side of the storage box, and the contact portion is further folded back at a portion where it contacts the left wall or the right wall, and the contact portion is folded back at the left wall Alternatively, the fourth pressing portion may be disposed between the storage box and the printing cassette in a state of abutting against the right wall, and when {X1 / a + (Y1 - Y2)} ≦ {Y1 / a + 2 × (X1 - X2)} is satisfied, the length of the fourth pressing portion before folding may be {X1 / a + (Y1 - Y2)} + C, and the fourth pressing portion may extend to the right or left from the upper edge of the left or right wall, be folded back downward at a position 1 / a with respect to the vertical side of the storage box, and further be folded back at the portion where it contacts the top wall, so that the fourth pressing portion is disposed between the storage box and the printing cassette in a state of abutting against the top wall. Since the positions of the fourth pressing portion and the first pressing portion can be set according to the left-right and up-down lengths of the storage box and the printing cassette, and the length of the fourth pressing portion can be made shorter, assembly of the printing cassette storage unit is facilitated. Furthermore, since the contact portion can be brought into contact with the left wall, the right wall or the top wall, the printing cassette can be pressed more reliably.

[0023] A first embodiment of the present invention will be described below with reference to the drawings. The drawings are used to explain technical features that can be adopted by the present invention. In other words, the configurations and the like shown in the drawings are merely illustrative examples and are not intended to limit the present invention.

[0024] The tape cassette 8 will be described with reference to FIG. 1. In the following description, the top, bottom, bottom right, top left, bottom left, and top right in FIG. 1 will be referred to as the top, bottom, front, rear, left, and right of the tape cassette 8, respectively. The orientation of the printing device 10 will be the orientation of the tape cassette 8 when it is installed, regardless of whether the tape cassette 8 is installed in the printing device 10 or not. Furthermore, the orientation of the storage box 1A, which will be described later, will be the orientation of the tape cassette 8 when it is stored in the storage box 1A (see FIG. 11). Note that in the first embodiment, the up-down direction, for example, is used for convenience of explanation and is not limited to the vertical direction.

[0025] The tape cassette 8 includes a case 81, a printing tape 89, and an ink ribbon 87. The case 81 is a generally rectangular parallelepiped that is longer in the left-right direction than in the front-to-back direction and longer in the up-down direction than in the left-to-right direction. The case 81 has a front wall 82, a rear wall 83, and a peripheral wall 84. The front wall 82 and the rear wall 83 each extend perpendicular to the front-to-back direction and are aligned with each other in the front-to-back direction. The front wall 82 is located at the front end of the case 81. The rear wall 83 is located at the rear end of the case 81. The peripheral wall 84 extends from a peripheral edge 831 of the rear wall 83 to a peripheral edge 821 of the front wall 82. The peripheral wall 84 is rectangular and includes a left wall 84A, a right wall 84B, a bottom wall 85, and an top wall 86. The left wall 84A and the right wall 84B each extend perpendicular to the left-to-right direction and are aligned with each other in the left-to-right direction. The left wall 84A is located at the left end of the case 81. The right wall 84B is located at the right end of the case 81. The bottom wall 85 and the top wall 86 each extend perpendicular to the up-down direction and are aligned with each other in the up-down direction. The bottom wall 85 is located at the bottom end of the case 81. The top wall 86 is located at the top end of the case 81. An outlet 88 is provided in the top wall 86 for discharging the printing tape 89 stored in the case 81 to the outside of the case 81. The outlet 88 is located at approximately the same height as the top wall 86 in the up-down direction, or slightly above it. The printing tape 89 is pulled out of the case 81 at the top of the left wall 84A, becomes exposed, and is guided to the outlet 88.

[0026] The printing tape 89 is long and wound around a cylindrical tape spool 89A and stored in the case 81. The tape spool 89A is located in the upper right section of the case 81, with both ends supported by the front wall 82 and the rear wall 83. A cylindrical hole 89B in the tape spool 89A is exposed to the outside of the case 81 at the front wall 82 and the rear wall 83. The cylindrical hole 89B is used to position the tape cassette 8 within the mounting section 11 of the printing device 10. The width direction (short direction) of the printing tape 89 is the front-to-rear direction. Therefore, the width direction of the tape cassette 8 is the front-to-rear direction. In the tape cassette 8, as the length in the width direction of the printing tape 89 (tape width) increases, the width of the case 81 in the front-to-rear direction also increases.

[0027] The ink ribbon 87 is long, wound around a ribbon spool (not shown), and stored in the case 81. The ink ribbon 87 passes through a path where it overlaps with the printing tape 89 midway along the path that the printing tape 89 takes from the tape spool 89A to the discharge port 88, and is then taken up by a cylindrical take-up spool 87A. The take-up spool 87A is located in the lower left portion of the case 81, and both ends are supported by the front wall 82 and the rear wall 83. The cylindrical hole of the take-up spool 87A is a cam hole 87B formed with a cam that inputs a driving force for winding the ink ribbon 87. The cam hole 87B is exposed to the outside of the case 81 at the front wall 82 and the rear wall 83.

[0028] Furthermore, protrusions 861, 851 are provided on the upper wall 86 and the lower wall 85 of the case 81, respectively. The protrusion 861 is rib-shaped and extends in the left-right direction while protruding upward from approximately the center of the upper wall 86, and is the structure that protrudes most upward on the upper wall 86. In other words, the protrusion 861 protrudes above the discharge port 88. The left and right ends of the protrusion 861 are each formed as ribs extending in the front-to-rear direction, and are H-shaped in plan view. The protrusion 851 is rib-shaped and extends in the left-to-right direction while protruding downward from approximately the center of the lower wall 85, and is the structure that protrudes most downward on the lower wall 85. The left and right ends of the protrusion 851 are each formed as ribs extending in the front-to-rear direction, and are H-shaped in bottom view.

[0029] A recess 80 is formed in the middle of the right part of the case 81 in the vertical direction, from the front wall 82 to the right peripheral wall 84. A label sticker indicating information about the tape cassette 8, such as the tape width, tape color, tape type, etc., is affixed to the recess 80.

[0030] The printer 10 has a recessed mounting section 11, which opens at the front, into which the tape cassette 8 is mounted. A hook 12 is formed near the inner wall of the recess at the top of the mounting section 11, extending forward from the bottom wall of the recess. A hook 13 is also formed near the inner wall of the recess at the bottom of the mounting section 11, extending forward from the bottom wall of the recess. When the tape cassette 8 is mounted in the mounting section 11 of the printer 10, the protrusions 861 and 851 engage with the hooks 12 and 13, respectively, and the tape cassette 8 is positioned and held in place.

[0031] The tape cassette 8 is a consumable item and is used for printing by the printer 10. With the tape cassette 8 attached to the attachment portion 11, the printer 10 pulls out the printing tape 89 from inside the case 81 at the exposed portion of the left wall 84A, while transferring ink from the ink ribbon 87 to the printing tape 89 using a print head (not shown), thereby printing an image. The printer 10 ejects the printing tape 89 with the printed image out of the case 81 through the ejection port 88. This creates a label with the image printed on the printing tape 89.

[0032] The storage box 1A will be described with reference to Figures 2 to 6. The storage box 1A is formed by assembling, for example, a backing board 100 shown in Figure 6. The storage box 1A comprises a box main body 2 and a header 3. The box main body 2 is a rectangular parallelepiped that is longer in the left-right direction than in the front-rear direction and is longer in the top-bottom direction than in the left-right direction, and stores tape cassettes 8. The box main body 2 has a bottom wall 4, a top wall 5, and peripheral walls 6. The bottom wall 4 and the top wall 5 extend perpendicular to each other in the top-bottom direction and are aligned with each other in the top-bottom direction. The bottom wall 4 is located at the bottom end of the box main body 2. The top wall 5 is located at the top end of the box main body 2.

[0033] The peripheral wall 6 extends from the peripheral edge 40 of the bottom wall 4 to the peripheral edge 50 of the top wall 5. The peripheral wall 6 is rectangular and cylindrical, and includes a front wall 61, a back wall 62, a left wall 63, and a right wall 64. The front wall 61 and the back wall 62 each extend perpendicular to the front-to-rear direction and are aligned with each other in the front-to-rear direction. The front wall 61 is located at the front end of the box body 2. The back wall 62 is located at the rear end of the box body 2. The left wall 63 and the right wall 64 each extend perpendicular to the left-to-right direction and are aligned with each other in the left-to-right direction. The left wall 63 is located at the left end of the box body 2. The right wall 64 is located at the right end of the box body 2. A lower end 611 of the front wall 61, a lower end 621 of the back wall 62, a lower end 631 of the left wall 63, and a lower end 641 of the right wall 64 form the peripheral edge 40 of the bottom wall 4 (see FIG. 3). An upper end 612 of the front wall 61, an upper end 622 of the back wall 62, an upper end 632 of the left wall 63, and an upper end 642 of the right wall 64 form the periphery 50 of the top wall 5 (see FIG. 2).

[0034] A space 7 is formed inside the box body 2. The space 7 is surrounded by a bottom wall 4, a top wall 5, and peripheral walls 6 (a front wall 61, a back wall 62, a left wall 63, and a right wall 64). The tape cassette 8 is placed in the space 7 with the bottom wall 85 of the case 81 facing the bottom wall 4 of the box body 2 from above.

[0035] The header 3 is provided on the box body 2. The header 3 is wall-shaped and includes a header piece 31 and a header piece 32. The header piece 31 is connected to an upper end 622 of the back wall 62 and extends upward from the upper end 622 of the back wall 62. An imaginary line V0 in FIG. 3 indicates the upper end 622 of the back wall 62. The header piece 32 is folded back forward from the upper end 311 of the header piece 31 and extends downward. The lower end 321 of the header piece 32 is located at the top wall 5 in the vertical direction and is connected to a female flap 52 (see FIG. 4) described below.

[0036] A hole 30 is provided in the header 3. The hole 30 has an isosceles triangular shape when viewed from the front, and is located in the left-right center of the header 3. The hole 30 penetrates the header pieces 31, 32 in the front-rear direction. Therefore, the hole 30 penetrates the header 3 in the front-rear direction. For example, in a distribution market for storage boxes 1A, the storage box 1A may be inserted through the hole 30 onto a rod for hanging and displaying products, and the storage box 1A may be hung and displayed.

[0037] As shown in Figures 3 and 6, the bottom wall 4 is a so-called bottom bottom and includes a male flap 41, a female flap 42, a left flap 43, and a right flap 44. The male flap 41 is connected to the lower end 621 of the back wall 62 and extends forward from the lower end 621 of the back wall 62. The male flap 41 has a trapezoidal shape that narrows toward the front. The female flap 42 is connected to the lower end 611 of the front wall 61 and extends rearward from the lower end 611 of the front wall 61. The female flap 42 has a rectangular shape that is longer in the left-right direction than in the front-to-back direction. An insertion port 421 is formed in the female flap 42. The insertion port 421 is longer in the left-to-right direction than in the front-to-back direction and penetrates the female flap 42 in the vertical direction. The left flap 43 is connected to the lower end 631 of the left wall 63 and extends rightward from the lower end 631 of the left wall 63. The right flap 44 is connected to the lower end 641 of the right wall 64 and extends leftward from the lower end 641 of the right wall 64. The left flap 43 and the right flap 44 are each triangular and bilaterally symmetrical to each other. The female flap 42, the left flap 43, the right flap 44, and the male flap 41 are stacked in that order from top to bottom to form the bottom wall 4.

[0038] As shown in Figures 2, 4 to 6, the top wall 5 includes a male flap 51, a female flap 52, a left flap 53, and a right flap 54. The male flap 51 is connected to the upper end 612 of the front wall 61 and has a male main body portion 515 and an insertion portion 55. The male main body portion 515 extends rearward from the upper end 612 of the front wall 61. The male main body portion 515 has a rectangular shape that is longer in the left-right direction than in the front-to-back direction. The length of the male main body portion 515 in the front-to-back direction is approximately the same as the distance between the front wall 61 and the back wall 62 in the front-to-back direction. The rear end 511 of the male main body portion 515 is located near the front of the back wall 62 and extends in the left-to-right direction. The male main body portion 515 has an opening 513 that penetrates the male main body portion 515 in the vertical direction. The opening 513 is where a user places their finger when opening the storage box 1A.

[0039] The insertion portion 55 connects to the male main body portion 515 and protrudes downward from the rear end 511 of the male main body portion 515. Specifically, the insertion portion 55 includes a base portion 57 and a barbed portion 58. The base portion 57 is the portion of the insertion portion 55 that extends downward from the male main body portion 515. The base portion 57 has a rectangular shape that is longer in the left-right direction than in the up-down direction. The base portion 57 connects to the male main body portion 515 at the center of the rear end 511 of the male main body portion 515 in the left-right direction, and both end portions are separated from the male main body portion 515. The barbed portion 58 is folded backward along a perforation at the bottom end 571 of the base portion 57 and extends upward. The barbed portion 58 is located between the back wall 62 and the base portion 57 in the front-to-rear direction and contacts the back wall 62.

[0040] The female flap 52 is connected to the upper end 622 of the back wall 62 via the header 3, extends forward from the lower end 321 of the header piece 32 (see FIG. 6), then folds back and extends rearward. The female flap 52 has a rectangular shape that is longer in the left-right direction than in the front-to-back direction. The front end 523 of the female flap 52 is located approximately in the center of the top wall 5 in the front-to-back direction. The female flap 52 is provided with a finger hook 522 and an insertion opening 521 (see FIG. 6). The finger hook 522 is recessed rearward from the center in the left-to-right direction at the front end 523 of the female flap 52. The finger hook 522 is arc-shaped and overlaps with the opening 513 in a plan view (see FIG. 4).

[0041] The insertion opening 521 is longer in the left-right direction than in the front-to-rear direction, and penetrates the female flap 52 in the up-down direction. The insertion opening 521 is located rearward of the center in the front-to-rear direction between the front wall 61 and the rear wall 62, and is located near the rear wall 62. In the first embodiment, the insertion opening 521 is located at the connection portion of the female flap 52 with the header piece 32 (the rear end of the female flap 52). The insertion portion 55 is inserted into the insertion opening 521.

[0042] The left flap 53 is connected to an upper end 632 of the left wall 63 and extends to the right from the upper end 632 of the left wall 63. The left flap 53 has a rectangular shape that is longer in the left-right direction than in the front-to-rear direction. A cutout 531 is provided in the left flap 53. The cutout 531 cuts out the rear end of the left flap 53 toward the front. The left-to-right length of the left flap 53 is shorter than the distance between the left wall 63 and the left wall 63 and is greater than half the distance between the left wall 63 and the left wall 63. The right flap 54 is connected to an upper end 642 of the right wall 64 and extends to the left from the upper end 642 of the right wall 64. The length of the right flap 54 in the front-to-rear direction is approximately the same as that of the left flap 53. A cutout 541 is provided in the right flap 54. The cutout 541 cuts out the rear end of the right flap 54 toward the front. The length of the right flap 54 in the left-right direction is shorter than the distance between it and the right wall 64 in the left-right direction and is approximately half the distance between it and the right wall 64 in the left-right direction. Therefore, one of the right end of the left flap 53 and the left end of the right flap 54 overlaps the other. In the first embodiment, the left flap 53 overlaps the right flap 54.

[0043] Hereinafter, the layer constituted by the male flaps 51 will be referred to as the "male flap layer 501." In the first embodiment, in a plan view, the outer shape of the male flap layer 501 is determined by the outer shape of the male main body portion 515. The layer constituted by the female flaps 52 will be referred to as the "female flap layer 502." In the first embodiment, in a plan view, the outer shape of the female flap layer 502 is determined by the outer shape of the female flaps 52. The layer constituted by the left flap 53 and the right flap 54 will be referred to as the "side flap layer 503." In the first embodiment, in a plan view, the outer shape of the side flap layer 503 is determined by the outer shapes of the left flap 53 and the right flap 54.

[0044] As shown in Fig. 5, in the top wall 5, the male flap layer 501, the female flap layer 502, and the side flap layer 503 are stacked in the order of female flap layer 502, side flap layer 503, and male flap layer 501 from bottom to top. The insertion portion 55 is disposed inside the female flap 52 via the insertion opening 521. As shown in Fig. 4, the left flap 53 and the right flap 54 are provided with cutouts 531 and 541, respectively, so that the side flap layer 503 does not overlap with the insertion opening 521 in a plan view.

[0045] The storage box 1A has a pressing portion 70 that presses the tape cassette 8 against the inner surface of the storage box 1A when the tape cassette 8 is stored therein (see FIG. 8 ). The pressing portion 70 is provided at the tip of the right flap 54 and is bent to be positioned in the gap between the top wall 5, which includes the right flap 54, and an upper wall 86 of the tape cassette 8 stored in the space 7. The pressing portion 70 comes into contact with the upper wall 86, thereby pressing the lower wall 85 of the tape cassette 8 against the inner surface of the bottom wall 4 of the storage box 1A. The pressing portion 70 has a connecting portion 71 and an abutting portion 72. The connecting portion 71 extends in the vertical direction from the portion of the right flap 54 that forms the top wall 5, and is a portion that comes into contact with the upper wall 86 of the tape cassette 8. The abutting portion 72 is connected to the portion of the connecting portion 71 that comes into contact with the tape cassette 8, and is a portion that can be bent relative to the connecting portion 71 in a direction along the upper wall 86 (for example, left and right). The abutment portion 72 is bent along the upper wall 86 at the portion where the connection portion 71 contacts the upper wall 86, thereby increasing the contact area between the pressing portion 70 and the upper wall 86 and preventing the tape cassette 8 from rotating around the portion where the connection portion 71 contacts inside the storage box 1A.

[0046] The mount 100 will be described with reference to Figure 6. Hereinafter, the left, right, bottom, and top of Figure 6 will be referred to as the negative X direction, positive X direction, negative Y direction, and positive Y direction of the mount 100, respectively. In Figure 6, imaginary lines V0, V1, V2, V3, V4, V5, V6, V7, V8, V9, V10, V11, V12, V13, V14, V15, and V16 indicate the boundaries between adjacent components of the storage box 1A. For example, imaginary line V0 indicates the boundary between the spine wall 62 and the header piece 31.

[0047] The mount 100 is a single sheet cut to a predetermined shape and is made of paper material such as thick paper, thin paper, or corrugated cardboard. The "back side" of the mount 100 is the side of the mount 100 shown in FIG. 6 that faces the back of the page, and is the side that faces the internal space 7 of the storage box 1A when the storage box 1A is assembled. The front side of the mount 100 may or may not be coated. The "front side" of the mount 100 is the side of the mount 100 shown in FIG. 6 that faces the front of the page, and is the side that faces the outside of the storage box 1A when the storage box 1A is assembled.

[0048] The mount 100 includes a bottom wall 4, a top wall 5, a peripheral wall 6, and a header 3. The peripheral wall 6 is located in the center of the mount 100 in the Y direction. In the peripheral wall 6, the front wall 61, the spine wall 62, the left wall 63, and the right wall 64 are arranged in succession from the positive X direction to the negative X direction in the order of right wall 64, front wall 61, left wall 63, and spine wall 62. Furthermore, a glue tab 65 is arranged adjacent to the spine wall 62 in the negative X direction.

[0049] The bottom wall 4 is disposed in the negative Y direction of the peripheral wall 6. Specifically, the male flap 41 is disposed in the negative Y direction of the back wall 62 and is connected to the back wall 62. The female flap 42 is disposed in the negative Y direction of the front wall 61 and is connected to the front wall 61. The left flap 43 is disposed in the negative Y direction of the left wall 63 and is connected to the left wall 63. The right flap 44 is disposed in the negative Y direction of the right wall 64 and is connected to the right wall 64.

[0050] The top wall 5 and the header 3 are arranged in the Y-positive direction of the peripheral wall 6. Specifically, in the header 3, the header piece 31 is arranged in the Y-positive direction of the back wall 62 and is continuous with the back wall 62. The header piece 32 is arranged in the Y-positive direction of the header piece 31 and is continuous with the header piece 31.

[0051] In the top wall 5, the female flap 52 is arranged in the positive Y direction of the header piece 31 and is connected to the header piece 31. The male flap 51 is arranged in the positive Y direction of the front wall 61 and is connected to the front wall 61. The left flap 53 is arranged in the positive Y direction of the left wall 63 and is connected to the left wall 63. The right flap 54 is arranged in the positive Y direction of the right wall 64 and is connected to the right wall 64. The pressing portion 70 is arranged in the positive Y direction of the right flap 54. The connecting portion 71 of the pressing portion 70 is arranged in the positive Y direction of the right flap 54 and is connected to the right flap 54. The abutting portion 72 of the pressing portion 70 is arranged in the positive Y direction of the connecting portion 71 and is connected to the connecting portion 71. The negative X end of the pressing portion 70 is at the same position in the X direction as the negative X end of the right flap 54. The positive X-direction end of the pressing portion 70 is located in the negative X-direction further than the positive X-direction end of the right flap 54. With this configuration, the pressing portion 70 does not interfere with the female flap 52 when assembling the storage box 1A.

[0052] 6 to 8, a procedure for storing tape cassettes 8 in a storage box 1A assembled from a mount 100 will be described. Folding the mount 100 along the boundary between a pair of adjacent components in a direction in which the back surfaces of the components face each other is called a "mountain fold." Folding the mount 100 along the boundary between a pair of adjacent components in a direction in which the front surfaces of the components face each other is called a "valley fold." For example, "mountain-folding the mount 100 along the imaginary line V1" means that the mount 100 is folded along the imaginary line V1 in a direction in which the back surfaces of the right wall 64 and the front wall 61 face each other. In the first embodiment, creases are formed on the front surface of the mount 100 along the imaginary lines V0 to V16. On the other hand, no creases are formed on the back surface of the mount 100.

[0053] As shown in Figure 6, the mount 100 is mountain-folded along imaginary lines V1, V2, V3, and V4, and the surface of the adhesive tab 65 is attached to the back surface of the left wall 63. This forms the peripheral wall 6 into a rectangular tubular shape (see Figure 2). In this state, the surface of the mount 100, including each flap, faces outward from the rectangular tubular shape, and the back surface faces inward, i.e., toward the space 7.

[0054] The backing paper 100 is mountain-folded along the imaginary line V5. As a result, the female flap 42 is arranged in the uppermost layer of the bottom wall 4 as the female flap layer 402. The backing paper 100 is mountain-folded along the imaginary lines V6 and V7. As a result, the left flap 43 and the right flap 44 are stacked below the female flap layer 402 as the side flap layer 403. The backing paper 100 is mountain-folded along the imaginary line V8. As a result, the male flap 41 is stacked below the side flap layer 403 as the male flap layer 401, and is arranged in the lowermost layer of the bottom wall 4. In this state, the male flap 41 is pushed inward from the outside.

[0055] When the male flap 41 is pushed inward from the outside, the tips of the male flap 41, left flap 43, and right flap 44 are inserted further inward than the female flap 42 through the insertion opening 421. As a result, the male flap 41, left flap 43, and right flap 44 are caught on the female flap 42 through the insertion opening 421, and a bottom wall 4 in the shape of a bottom of a hole is formed (see Figure 3).

[0056] Once the bottom wall 4 is formed, the box body 2 opens upward (see FIG. 3). In this state, as shown in FIG. 7, the tape cassette 8 is stored in the space 7 from above the box body 2. The tape cassette 8 is stored in the space 7 so that the rear wall 83 faces the underside of the spine wall 62 of the storage box 1A from the front and the bottom wall 85 faces the underside of the bottom wall 4 from above. The backing sheet 100 is mountain-folded along imaginary line V9 and valley-folded along imaginary line V10. As a result, the header 3 is formed, and the female flap layer 502 is disposed as the lowest layer of the top wall 5, as shown in FIG.

[0057] The backing sheet 100 is mountain-folded along imaginary lines V16 and V15. As a result, a pressing portion 70 that is folded into a generally U-shape when viewed from the front is formed at the tip of the right flap 54. The backing sheet 100 is further mountain-folded along imaginary line V12. The right flap 54 is disposed on the female flap layer 502 that constitutes the bottom layer of the top wall 5. The connecting portion 71 of the pressing portion 70 is disposed so as to extend downward from the left end of the right flap 54, and its lower end contacts the top wall 86 of the case 81 of the tape cassette 8. The abutting portion 72 of the pressing portion 70 is disposed so as to extend rightward from the lower end of the connecting portion 71, and its lower surface contacts the top wall 86 of the case 81. The rear end of the pressing portion 70 is located forward of the rear end of the right flap 54. Therefore, the pressing portion 70 does not contact the female flap 52 that was folded earlier and disposed at the bottom layer of the top wall 5.

[0058] The backing sheet 100 is mountain-folded along the imaginary line V11. The right end of the left flap 53 is placed on top of the left end of the right flap 54. The left flap 53 and the right flap 54 form a side flap layer 503, which is layered on top of the female flap layer 502 that forms the bottom layer of the top wall 5. The backing sheet 100 is mountain-folded along the imaginary line V13 and valley-folded along the perforation at the bottom end 571 of the base portion 57. This forms the insertion portion 55. The backing sheet 100 is mountain-folded along the imaginary line V14. The insertion portion 55 is inserted inwardly relative to the female flap 52 through the insertion opening 521. As a result, the male flap layer 501 is layered on top of the side flap layer 503, and the top wall 5 shown in FIG. 2 is formed. With the above, the assembly of the storage box 1A and the storage of the tape cassette 8 inside the storage box 1A are completed, and the printing cassette storage body 20 (however, the printing cassette storage body 20 in Figure 8 is in a state before the top wall 5 is formed) is completed.

[0059] The amount of material used to produce the mount 100 can be reduced by the configuration of the pressing portion 70. For example, as shown in FIG. 9(A), the pressing portion 70 of the first embodiment has a configuration in which the connection portion 71 is disposed in the gap between the top wall 5 of the storage box 1A and the upper wall 86 of the case 81, thereby pressing the tape cassette 8 against the inner surface of the bottom wall 4 inside the storage box 1A. Let us consider the lengths of the right flap 54 and the pressing portion 70 in the Y direction before the pressing portion 70 is folded on the mount 100. Let X1 be the left-right length of the storage box 1A, Y1 be the up-down length of the storage box 1A, X2 be the left-right length of the case 81 of the tape cassette 8, and Y2 be the up-down length of the case 81. In the storage box 1A, the right flap 54 after folding extends leftward from the upper end of the right wall 64, and its left end is at a position 1 / a of the left-right length X1 of the storage box 1A. The connecting portion 71 is bent downward from the left end of the right flap 54. The connecting portion 71 has a length (Y1-Y2), which is the difference between the vertical length Y1 of the storage box 1A and the vertical length Y2 of the case 81, and is therefore able to come into contact with the top wall 86 of the case 81 and press the tape cassette 8 against the inner surface of the bottom wall 4. Therefore, the length of the right flap 54 and the pressing portion 70 can be expressed as {X1 / a+(Y1-Y2)}.

[0060] On the other hand, if the orientation or shape of the tape cassettes 8 stored in the storage box 1A is different, for example, as shown in Figure 9(B) when the tape cassettes 8 are stored in the storage box 1A with the left wall 84A of the case 81 facing downward, the shape of the storage box 1A will be longer in the left-right direction than in the up-down direction. In this case, if the connecting portion 71 is disposed in the gap between the top wall 5 of the storage box 1A and the upper wall 86 of the case 81, as in the pressing portion 70, the length X1 / a of the right flap 54 will be longer, and therefore more material will be used for the backing sheet 100. Therefore, a configuration is being considered in which the pressing portion 75 is disposed in the gap between the right wall 64 of the storage box 1A and the lower wall 85 of the case 81 that faces the right wall 64, as in the pressing portion 75. The pressing portion 75 has a connecting portion 77 and a connecting portion 76 connected in order to the right flap 54, and the connecting portion 76 is disposed in the gap between the right wall 64 of the storage box 1A and the bottom wall 85 of the case 81, thereby pressing the tape cassette 8 against the inner surface of the left wall 63 inside the storage box 1A. In the storage box 1A, the folded right flap 54 extends leftward from the upper end of the right wall 64, with its left end at a position that reaches a length (X1-X2), which is the difference between the left-right length X1 of the storage box 1A and the left-right length X2 of the case 81. The connecting portion 77 is folded downward from the left end of the right flap 54. The connecting portion 77 extends to a position 1 / a of the vertical length Y1 of the storage box 1A, and the connecting portion 76 connected to the connecting portion 77 is folded rightward. The connecting portion 76 has a length (X1-X2), which allows it to come into contact with the right wall 64 of the storage box 1A and the bottom wall 85 of the case 81, and press the tape cassette 8 against the inner surface of the left wall 63. Therefore, the length of the right flap 54 and the pressing portion 75 can be expressed as {Y1 / a+2×(X1-X2)}.

[0061] When {X1 / a+(Y1-Y2)}>{Y1 / a+2×(X1-X2)} is satisfied, the pressing portion 75 uses less material for the backing sheet 100 than the pressing portion 70. Therefore, in this case, the pressing portion 75 is adopted. The length of the right flap 54 and the pressing portion 75 before folding the pressing portion 75 is {Y1 / a+2×(X1-X2)}. When {X1 / a+(Y1-Y2)}≦{Y1 / a+2×(X1-X2)} is satisfied, the amount of material used for the pressing portion 70 is less than the pressing portion 75. Therefore, in this case, the pressing portion 70 is adopted. The length of the right flap 54 and the pressing portion 70 before folding the pressing portion 70 is {X1 / a+(Y1-Y2)}.

[0062] The pressing portions 70 and 75 may each include abutting portions 72 and 78. The length of the abutting portions 72 and 78 is defined as C. The length of the pressing portion 75 to be used when {X1 / a+(Y1-Y2)}>{Y1 / a+2×(X1-X2)} is satisfied is {Y1 / a+2×(X1-X2)}+C. The length of the pressing portion 70 to be used when {X1 / a+(Y1-Y2)}≦{Y1 / a+2×(X1-X2)} is satisfied is {X1 / a+(Y1-Y2)}+C.

[0063] As explained above, the pressing section 70 of the first embodiment presses the tape cassette 8 against the inner surface of the storage box 1A. Therefore, by eliminating the gap between the tape cassette 8 and the storage box 1A, the printing cassette storage body 20 makes it difficult for the storage box 1A and the tape cassette 8 to rub against each other due to vibrations during transportation, etc., and can suppress the generation of paper dust. Furthermore, because the pressing section 70 is part of the storage box 1A and not a separate component, the production costs of the storage box 1A can be suppressed.

[0064] The pressing portion 70 contacts the top wall 86 of the case 81 of the tape cassette 8 inside the storage box 1A, but does not contact the left wall 84A where the printing tape 89 is exposed, and therefore does not come into contact with the printing tape 89. Therefore, the printing cassette storage body 20 can prevent damage to the printing tape 89 due to vibrations during transportation, etc.

[0065] Furthermore, the pressing section 70 presses the lower wall 85 of the tape cassette 8 against the inner surface of the bottom wall 4 of the storage box 1A, and does not press the left wall 84A, on which the printing tape 89 is exposed, against the left wall 63 of the storage box 1A. Therefore, the printing cassette storage body 20 can prevent damage to the printing tape 89 due to vibrations during transportation, etc.

[0066] Pressing portion 70 is formed by folding right flap 54 of storage box 1A. Compared to forming a U-shaped cutout in the outer surface of storage box 1A and folding it back inward, this eliminates the need to form holes or the like in storage box 1A. Also, the portion of right flap 54 that abuts against tape cassette 8 is further folded to form abutting portion 72, and by bringing abutting portion 72 into face-to-face contact with tape cassette 8, tape cassette 8 can be pressed more reliably.

[0067] By appropriately employing the pressing part 70 or the pressing part 75 according to the left-right and up-down lengths of the storage box 1A and the tape cassette 8 and setting their positions, the lengths of the pressing parts 70, 75 and the right flap 54 can be made shorter, making it easier to assemble the printing cassette storage body 20.

[0068] Furthermore, the pressing portions 70 and 75 can bring the contact portions 72 and 78 into contact with the upper wall 86 (the surface facing the top wall 5) and the lower wall 85 (the surface facing the right wall 64) of the tape cassette 8, respectively, so that the tape cassette 8 can be pressed more reliably.

[0069] The first embodiment may be modified in various ways. The various modifications described below may be combined with each other as long as no contradictions arise. The pressing portion 70 is not limited to being formed on the right flap 54, but may also be formed on the left flap 53. Alternatively, it may be formed on the right flap 44 or left flap 43 of the bottom wall 4. The abutment portions 72, 78 of the pressing portions 70, 75 may be omitted.

[0070] As shown in FIG. 10 , the storage box 1A may be provided with pressing portions 170, 175, and 180 that press the tape cassette 8 against the inner surface of the storage box 1A in the up-down direction, left-right direction, and front-rear direction. The pressing portion 170 has a configuration similar to the pressing portion 70 and is provided adjacent to the left flap 53. In the storage box 1A, the folded left flap 53 extends rightward from the upper end of the left wall 63, with its left end located approximately in the center of the storage box 1A in the left-right direction. The connecting portion 171 is folded downward from the left end of the left flap 53 and comes into contact with the upper wall 86 of the tape cassette 8. The abutting portion 172 is folded leftward from the lower end of the connecting portion 171, with its lower surface coming into contact with the upper wall 86.

[0071] The pressing portion 175 has the same configuration as the pressing portion 75, and is provided adjacent to the right flap 54. In the storage box 1A, the folded right flap 54 has its left end at a position extending a length (X1-X2) to the left from the upper end of the right wall 64. The connecting portion 177 extends downward from the left end of the right flap 54, and its lower end is located approximately in the center of the storage box 1A in the up-down direction. The connecting portion 176 extends a length (X1-X2) to the right from the lower end of the connecting portion 177, and comes into contact with the right wall 64. The abutting portion 178 is bent upward from the right end of the connecting portion 176, and its right surface comes into contact with the right wall 64.

[0072] The pressing portion 180 is provided adjacent to the pressing portion 175. In the storage box 1A, the front end of the pressing portion 175 contacts the inner surface of the front wall 82 of the storage box 1A. The connecting portion 181 of the pressing portion 180 extends leftward from the front end of the connecting portion 177 of the pressing portion 175, with its left end located approximately in the center of the storage box 1A in the left-right direction. The connecting portion 182 extends rearward from the left end of the connecting portion 181 by a length obtained by subtracting the front-to-back length of the case 81 of the tape cassette 8 from the front-to-back length of the storage box 1A, and its rear end contacts the front wall 61 of the tape cassette 8. The abutting portion 183 is bent rightward from the rear end of the connecting portion 182, with its rear surface contacting the front wall 61.

[0073] In this way, the printing cassette storage body 20 may use each of the pressing portions 170, 175, and 180 to press the tape cassette 8 against the inner surfaces of the bottom wall 4, left wall 63, and back wall 62 of the storage box 1A. Of course, the printing cassette storage body 20 does not have to be equipped with all of the pressing portions 170, 175, and 180, and may be equipped with only one or two of them. Also, the pressing portion 170 may be provided on the right flap 54, and the pressing portions 175 and 180 may be provided on the left flap 53. The pressing portions 170, 175, and 180 press the tape cassette 8 against the inner surface of the storage box 1A in multiple directions, making it less likely that the storage box 1A and the tape cassette 8 will rub against each other due to vibrations during transportation, etc., and reducing the generation of paper dust.

[0074] As shown in FIG. 11 , the pressing portions 270, 275 may be formed on part of the outer surface of the storage box 1A, rather than on flaps. The pressing portions 270, 275 are inside portions of cutouts 270A, 275A formed in the right wall 64 of the storage box 1A. The cutout 270A is a generally U-shaped cutout formed above the vertical center of the right wall 84B, and is longer in the front-to-back direction than in the vertical direction. The cutout 275A is a generally U-shaped cutout formed below the vertical center of the right wall 84B, and is longer in the front-to-back direction than in the vertical direction. The vertical length of the cutouts 270A, 275A is the length (X1-X2) obtained by subtracting the horizontal length of the case 81 of the tape cassette 8 from the horizontal length of the storage box 1A. Pressing portions 270, 275 are pushed into the interior of storage box 1A and are positioned in the gap between right wall 64 and right wall 84B of case 81 of tape cassette 8. The right ends of pressing portions 270, 275 each come into contact with right wall 84B. By forming the inner portions of cutouts 270A, 275A formed in right wall 64 of storage box 1A as pressing portions 270, 275, the unfolded area of ​​backing 100 before storage box 1A is assembled can be smaller than when pressing portions 270, 275 are formed as flaps, thereby reducing the production cost of storage box 1A.

[0075] Furthermore, if only one of the pressing portions 270, 275 is formed on the right wall 64, there is a possibility that the tape cassette 8 will tilt inside the storage box 1A due to vibrations during transport or the like, with the portion of the tape cassette 8 that abuts against the left end of the pressing portion 270 or 275 as a fulcrum. By forming the pressing portions 270, 275 on the right wall 64, the pressing portions 270, 275 can press the tape cassette 8 against the inner surface of the left wall 63 of the storage box 1A, thereby holding it down at two or more points, and therefore making it possible to prevent the tape cassette 8 from tilting inside the storage box 1A.

[0076] The pressing portions 270, 275 may be formed not only on the right wall 64 of the storage box 1A but also on other outer surfaces such as the left wall 63 or the front wall 61. Also, a pair of pressing portions 270, 275 may be provided at multiple locations, for example, on the right wall 64 and the front wall 61, respectively.

The cut portions 270A, 275A are examples of "cut portions" in the first aspect of the present invention.

[0078] Next, a second embodiment of the present invention will be described. In the printing cassette storage unit 20 of the second embodiment, a pressing portion is not provided on the storage box 1B, but a pressing portion 90 is provided on the mounting member 9 that is attached to the tape cassette 8. By storing the tape cassette 8 and the mounting member 9 in the storage box 1B, the pressing portion 90 presses the tape cassette 8 against the inner surface of the storage box 1B, reducing friction between the tape cassette 8 and the storage box 1B. Therefore, the storage box 1B has the same configuration as the storage box 1A except that it does not have the pressing portion 70. Therefore, in the following description, the configuration of the storage box 1B will be assumed to be the same as the configuration of the storage box 1A of the first embodiment, and descriptions of the configuration and assembly will be omitted.

[0079] The mounting member 9 will be described with reference to FIG. 12. The mounting member 9 is attached to the tape cassette 8 when storing the tape cassette 8 in the storage box 1B (see FIG. 13), and is stored in the storage box 1B together with the tape cassette 8. The mounting member 9 is formed by assembling a mounting board 200 shown in FIG. 12. Hereinafter, the left, right, bottom, and top of FIG. 12 will be referred to as the negative X direction, positive X direction, negative Y direction, and positive Y direction of the mounting board 200, respectively. In FIG. 12, imaginary lines V21, V22, V23, V24, and V25 indicate the boundaries between adjacent components of the mounting member 9. For example, imaginary line V21 indicates the boundary between connecting portion 92 and connecting portion 93. The mounting board 200 is a sheet cut to a predetermined shape and is made of a paper material such as cardboard, thin paper, or corrugated cardboard. The "rear surface" of the mounting board 200 is the surface of the mounting board 200 shown in Fig. 12 facing the back of the paper. The "front surface" of the mounting board 200 is the surface of the mounting board 200 shown in Fig. 12 facing the front of the paper.

[0080] The mounting member 9 has a positioning portion 91 and a pressing portion 90. The positioning portion 91 is a portion that is disposed facing the front wall 82 of the tape cassette 8 and is shaped like a rectangular plate. When the positioning portion 91 is disposed facing the front wall 82, the right end of the positioning portion 91 is located at the same position as the right wall 84B of the case 81 when viewed from the front. Cutouts 96A and 97A are formed in the positioning portion 91. The cutout 96A is a cut portion formed in positions in the negative X direction and the negative Y direction from the center of the positioning portion 91. The cutout 96A is approximately U-shaped extending in the Y direction, and the positive Y direction side and both X direction sides are cut in the thickness direction of the mounting base 200, leaving the negative Y direction side. The inner portion of the cutout 96A is a protruding piece 96, which is used by being folded to the back side along the negative Y direction side (imaginary line V24). When the mounting member 9 is mounted on the tape cassette 8, the protruding piece 96 is inserted into the cam hole 87B of the take-up spool 87A that opens in the front wall 82 of the tape cassette 8.

[0081] The notch 97A is a notch formed in a position in the positive X direction and the positive Y direction from the center of the positioning portion 91. The notch 97A is roughly U-shaped extending in the Y direction, and the negative Y direction side and both X direction sides are cut in the thickness direction of the mounting base 200, leaving the positive Y direction side. The inner part of the notch 97A is a protruding piece 97, which is used by being folded back along the positive Y direction side (imaginary line V25). When the mounting member 9 is mounted in the tape cassette 8, the protruding piece 97 is inserted into a cylindrical hole 89B of a tape spool 89A that opens in the front wall 82 of the tape cassette 8.

[0082] The pressing portion 90 is disposed in the positive X direction of the positioning portion 91. The pressing portion 90 has connecting portions 92, 93, and 94 and an abutting portion 95. The connecting portion 92 is disposed in the positive X direction of the positioning portion 91 and is formed on the same plane as the positioning portion 91. The length of the connecting portion 92 in the X direction is the length (X1-X2) obtained by subtracting the length of the case 81 of the tape cassette 8 in the left-right direction from the length of the storage box 1B. The connecting portion 93 is disposed in the positive X direction of the connecting portion 92 and is continuous with the connecting portion 92. The length of the connecting portion 93 in the X direction is shorter than the length of the case 81 of the tape cassette 8 in the front-to-rear direction, for example, approximately half the length of the case 81 in the front-to-rear direction. The connecting portion 94 is disposed in the positive X direction of the connecting portion 93 and is continuous with the connecting portion 93. The length of the connecting portion 94 in the X direction is the length (X1-X2) obtained by subtracting the length of the case 81 of the tape cassette 8 in the left-right direction from the length of the storage box 1B in the left-right direction. The abutting portion 95 is disposed in the positive X direction of the connecting portion 94 and is continuous with the connecting portion 94. The length of the abutting portion 95 in the X direction is shorter than the length of the connecting portion 94 in the X direction.

[0083] The mounting member 9 is assembled by folding the mounting base 200 and then mounted in the tape cassette 8. As shown in FIGS. 12 and 13 , the mounting base 200 is mountain-folded along imaginary lines V23 and V22. As a result, the abutting portion 95 and the connecting portion 94 are bent at the right end of the connecting portion 93 in a generally U-shape when viewed from above. The mounting base 200 is then mountain-folded along imaginary line V21. The connecting portion 92 is flush with the positioning portion 91, and therefore, when mounted in the tape cassette 8, it protrudes to the right of the positioning portion 91 by a length (X1-X2) beyond the right wall 84B of the tape cassette 8. The connecting portion 93 extends rearward from the right end of the connecting portion 92 by approximately half the length in the front-to-rear direction of the case 81. The connecting portion 94 extends leftward from the rear end of the connecting portion 93 by a length (X1-X2). The abutment portion 95 extends forward from the left end of the connection portion 94. The protruding pieces 96 and 97 of the positioning portion 91 are bent in a mountain shape at imaginary lines V24 and V25, respectively. In this state, the mounting member 9 is attached to the tape cassette 8, and the protruding pieces 96 and 97 are inserted into the cam hole 87B and the cylindrical hole 89B (see Figure 12). This positions the positioning portion 91 relative to the front wall 82 of the tape cassette 8. The left end of the connection portion 94 contacts the right wall 84B of the case 81. The left surface of the abutment portion 95 contacts the right wall 84B of the case 81.

[0084] As shown in FIG. 13 , the storage box 1B is assembled with the bottom wall 4 formed and the top wall 5 open, similar to the first embodiment. The tape cassette 8 with the mounting member 9 attached is stored in the space 7 from above the storage box 1B. The positioning portion 91 of the mounting member 9 is disposed between the front wall 82 of the tape cassette 8 and the inner surface of the front wall 61 of the storage box 1B. The right end of the connecting portion 92, which is formed on the same surface as the positioning portion 91, contacts the inner surface of the right wall 84B of the storage box 1B. The right surface of the connecting portion 93 also contacts the inner surface of the right wall 84B of the storage box 1B. The right end of the connecting portion 94 contacts the inner surface of the right wall 84B of the storage box 1B, and the left end contacts the right wall 84B of the case 81. The abutting portion 95 contacts the right wall 84B of the case 81. Therefore, the connecting portion 94 of the pressing portion 90 presses the tape cassette 8 against the inner surface of the left wall 84A inside the storage box 1B.

[0085] Thereafter, as in the first embodiment, the backing sheet 100 is mountain-folded along the imaginary line V9 and valley-folded along the imaginary line V10. This forms the header 3, and the female flap layer 502 is placed as the bottom layer of the top wall 5. The backing sheet 100 is mountain-folded along the imaginary lines V11 and V12. This results in a side flap layer 503 composed of a left flap 43 and a right flap 54 being stacked on top of the female flap layer 502 in the top wall 5. Note that the stacking order of the left flap 43 and the right flap 54 in the side flap layer 503 is arbitrary. The backing sheet 100 is mountain-folded along the imaginary line V13 and valley-folded along the perforation at the bottom end 571 of the base portion 57. This forms the insertion portion 55.

[0086] The backing sheet 100 is mountain-folded along the imaginary line V14. The insertion portion 55 is inserted through the insertion opening 521 and further inward than the female flap 52. As a result, the male flap layer 501 is stacked on top of the side flap layer 503, forming the top wall 5. This completes the assembly of the storage box 1B and the mounting member 9, and the storage of the tape cassette 8 in the storage box 1B, completing the printing cassette storage unit 20 shown in Figure 14.

[0087] As explained above, when the mounting member 9 of the second embodiment is attached to the tape cassette 8 and stored in the storage box 1B, the pressing portion 90 is positioned in the gap between the tape cassette 8 and the inner surface of the right wall 84B. Therefore, by eliminating the gap between the tape cassette 8 and the storage box 1B, the printing cassette storage body 20 makes it less likely for the storage box 1B and the tape cassette 8 to rub against each other due to vibrations during transportation, etc., and can suppress the generation of paper dust. Furthermore, because the mounting member 9 with the pressing portion 90 pre-assembled is attached to the tape cassette 8 and stored in the storage box 1B, assembly of the printing cassette storage body 20 is easier than when the pressing portion 90 is formed by folding back a flap.

[0088] The mounting member 9 is made from a single sheet of mounting base 200, and the protruding pieces 96, 97 are simply inserted into the cam hole 87B and the cylindrical hole 89B of the tape cassette 8, and the connecting part 92 can be positioned in the storage box 1B at a position corresponding to the gap between the tape cassette 8 and the inner surface of the right wall 84B without any processing such as folding the sheet.

[0089] Connection portion 94, which is connected to connection portion 92 via connection portion 93, is folded back and comes into contact with tape cassette 8, so that pressing portion 90 is supported by connection portions 92 and 94. Therefore, pressing portion 90 is less likely to deform due to vibrations during transportation, etc., and mounting member 9 makes it less likely for storage box 1B and tape cassette 8 to rub against each other, thereby suppressing the generation of paper dust.

[0090] The second embodiment may be modified in various ways. The various modified examples described below may be combined with each other as long as no contradictions arise. In a first modified example of the second embodiment, a single mounting member 409 may be used to press the tape cassette 8 against the inner surface of the storage box 1B in two directions, for example, the left-right direction and the front-rear direction, as in the mounting member 409 shown in FIG. 15 . The mounting member 409 has a positioning portion 491 and a pressing portion 490. The positioning portion 491 is positioned relative to the front wall 82 of the tape cassette 8 by inserting the protruding pieces 96 and 97 into the cam hole 87B and the cylindrical hole 89B of the tape cassette 8, respectively. The pressing portion 490 has connecting portions 492, 493, 494, and 495 and an abutting portion 496. The connecting portion 492 is located to the right of the positioning portion 491 and is formed on the same plane as the positioning portion 491. The right end of the connecting portion 492 contacts the inner surface of the right wall 64 of the storage box 1B. Connection portion 493 extends rearward from the right end of connection portion 492 by the length of storage box 1B in the front-to-rear direction. The rear end of connection portion 493 contacts the inner surface of back wall 62 of storage box 1B. Connection portion 494 extends leftward from the rear end of connection portion 493 by approximately half the length of storage box 1B in the left-to-right direction. Connection portion 495 extends forward from the left end of connection portion 494 by a length obtained by subtracting the length of case 81 of tape cassette 8 in the front-to-rear direction from the length of storage box 1B in the front-to-rear direction. Therefore, the rear end of connection portion 495 contacts the inner surface of back wall 62 of storage box 1B, and its front end contacts rear wall 83 of case 81. Abutment portion 496 extends rightward from the front end of connection portion 495, and its front surface contacts rear wall 83 of case 81.

[0091] With this configuration, the mounting member 409 presses the tape cassette 8 against the inner surface of the left wall 63 of the storage box 1B by the connection part 492, and presses the tape cassette 8 against the inner surface of the front wall 61 of the storage box 1B by the connection part 495. Therefore, the mounting member 409 can press the tape cassette 8 against the inner surface of the storage box 1B in the left-right direction and the front-back direction.

[0092] Furthermore, in the first modified example, the tape cassette 8 is stored upside down in the storage box 1B, with the left wall 84A facing the inner surface of the right wall 64 of the storage box 1B. The printing tape 89 is exposed to the outside at the left wall 84A of the tape cassette 8. The mounting member 409 can cover the exposed portion of the printing tape 89 from the front, rear, and right sides with the connecting portions 492, 493, and 494 of the pressing portion 490. Therefore, the printing tape 89 exposed from the tape cassette 8 does not come into contact with the inner surface of the storage box 1B, and the printing cassette storage body 20 can prevent damage to the printing tape 89 due to vibrations during transportation, etc. Furthermore, when removing the tape cassette 8 from the storage box 1B, it is difficult for the user to touch the printing tape 89 with the mounting member 409 attached, so damage to the printing tape 89 can be prevented.

[0093] Furthermore, in the first modified example, the left flap 53 of the storage box 1B has a pressing portion 470 similar to that of the first embodiment. The left flap 53 extends rightward from the upper end of the left wall 63, with its right end located approximately in the center in the left-right direction. The pressing portion 470 has a connecting portion 471 and an abutting portion 472. The connecting portion 471 extends downward from the right end of the left flap 53 by a length (Y1-Y2) obtained by subtracting the vertical length of the case 81 from the vertical length of the storage box 1B. Therefore, the upper end of the connecting portion 471 contacts the inner surface of the top wall 5 of the storage box 1B, and the lower end contacts the bottom wall 85 of the case 81 of a tape cassette 8 stored upside down. The abutting portion 472 extends leftward from the lower end of the connecting portion 471, with its lower surface contacting the bottom wall 85 of the case 81. In this way, the pressing portion 490 provided on the mounting member 409 and the pressing portion 470 provided on the left flap 53 may be used in combination to press the tape cassette 8 against the inner surface of the storage box 1B in multiple directions (three directions in the first variant).

[0094] The pressing portion 490 comes into contact with the inner surface of the right wall 64 of the storage box 1B and presses the tape cassette 8 against the inner surface of the left wall 63. The pressing portion 470 comes into contact with the inner surface of the top wall 5 of the storage box 1B and presses the tape cassette 8 against the inner surface of the bottom wall 4. Therefore, by eliminating gaps between the tape cassette 8 and the storage box 1B in at least two directions, the printing cassette storage body 20 makes it less likely for the storage box 1B and the tape cassette 8 to rub against each other due to vibrations during transportation, etc., and suppresses the generation of paper dust. Furthermore, because the pressing portion 490 presses against the inner surface of the left wall 63 and the pressing portion 470 presses against the bottom wall 4, it is not necessary for the pressing portion 490 of the mounting member 9 and the pressing portion 470 of the left flap 53 to have complex shapes, which makes it easier to assemble the printing cassette storage body 20.

[0095] Furthermore, by storing the tape cassette 8 upside down in the storage box 1B as in the first modified example, it is possible to press the right wall 84B, where the printing tape 89 is not exposed, against the inner surface of the left wall 63 of the storage box 1B, rather than the left wall 84A, where the printing tape 89 is exposed. Therefore, the printing tape 89 exposed from the tape cassette 8 is not pressed against the inner surface of the left wall 63 of the storage box 1B, and the printing cassette storage body 20 can prevent damage to the printing tape 89 due to vibrations during transportation, etc.

[0096] In a second modified example of the second embodiment, for example, as in mounting member 509 shown in Fig. 16, a single sheet may be folded to press tape cassette 8 against the inner surface of storage box 1B in three directions: up-down, left-right, and front-rear. Mounting member 509 has a positioning portion 591 and pressing portions 590, 690, and 790. Positioning portion 591 is positioned with respect to front wall 82 of tape cassette 8 by inserting protruding pieces 96 and 97 into cam hole 87B and cylindrical hole 89B of tape cassette 8, respectively.

[0097] The pressing portion 590 has connecting portions 592, 593, 594 and an abutting portion 595. The connecting portion 592 is located to the right of the positioning portion 591 and is formed on the same plane as the positioning portion 591. The right end of the connecting portion 592 contacts the inner surface of the right wall 64 of the storage box 1B. The connecting portion 593 extends rearward from its right end by approximately half the length of the case 81 in the front-to-rear direction. The connecting portion 594 extends leftward from its rear end by a length obtained by subtracting the length of the case 81 of the tape cassette 8 from the left-to-right length of the storage box 1B in the left-to-right direction. Therefore, the right end of the connecting portion 594 contacts the inner surface of the back wall 62 of the storage box 1B, and the left end contacts the right wall 84B of the case 81. The contact portion 595 extends forward from the left end of the connection portion 594, and its left surface comes into contact with the right wall 84B of the case 81. Thus, the pressing portion 590 presses the tape cassette 8 against the inner surface of the left wall 63 of the storage box 1B.

[0098] The pressing portion 690 has connecting portions 692, 693, and 694 and an abutting portion 695. The connecting portion 692 is disposed above the positioning portion 591 and is formed on the same plane as the positioning portion 591. The upper end of the connecting portion 692 contacts the inner surface of the top wall 5 of the storage box 1B. The connecting portion 693 extends rearward from the upper end of the connecting portion 692 by approximately half the length of the case 81 in the front-to-rear direction. The connecting portion 694 extends downward from the rear end of the connecting portion 693 by a length obtained by subtracting the vertical length of the case 81 of the tape cassette 8 from the vertical length of the storage box 1B. Therefore, the upper end of the connecting portion 694 contacts the inner surface of the top wall 5 of the storage box 1B, and the lower end contacts the top wall 86 of the case 81. The abutting portion 695 extends forward from the lower end of the connecting portion 694, and its lower surface contacts the top wall 86 of the case 81. Therefore, the pressing portion 690 presses the tape cassette 8 against the inner surface of the bottom wall 4 of the storage box 1B.

[0099] The pressing portion 790 has connecting portions 792, 793, 794 and an abutting portion 795. The connecting portion 792 extends rearward from the lower end of the positioning portion 591 by a length obtained by subtracting the length of the case 81 of the tape cassette 8 from the length of the storage box 1B in the front-to-rear direction. The front end of the connecting portion 792 contacts the inner surface of the front wall 82 of the storage box 1B. The connecting portion 793 extends upward from the front end of the connecting portion 792 by approximately half the length of the case 81 in the up-and-down direction. The connecting portion 794 extends rearward from the upper end of the connecting portion 793 by a length obtained by subtracting the length of the case 81 of the tape cassette 8 from the length of the storage box 1B in the front-to-rear direction. Therefore, the front end of the connecting portion 794 contacts the inner surface of the front wall 61 of the storage box 1B, and the rear end contacts the front wall 82 of the case 81. The contact portion 795 extends downward from the rear end of the connection portion 794, and its rear surface comes into contact with the front wall 82 of the case 81. Thus, the pressing portion 790 presses the tape cassette 8 against the inner surface of the back wall 62 of the storage box 1B.

[0100] In this way, the mounting member 509 of the second modified example presses the tape cassette 8 against the inner surface of the storage box 1B in multiple directions (three directions in the second modified example), making it less likely that the storage box 1B and the tape cassette 8 will rub against each other due to transport vibrations, etc., and suppressing the generation of paper dust.

[0101] In other modifications of the second embodiment, the number of protruding pieces 96, 97 of the positioning portion 91 is not limited to two, but may be one, or may be three or more. The portions into which the protruding pieces 96, 97 are inserted are not limited to the cylindrical hole 89B and the cam hole 87B, but may be other holes or recesses.

[0102] Furthermore, it may be combined as appropriate with the modified examples of the first embodiment. For example, in the first modified example of the second embodiment, the pressing portion 470 is provided on the left flap 53, but the position and length of the pressing portion 470 may be set depending on whether the lengths of the flap and the pressing portion described in the first embodiment satisfy {X1 / a+(Y1-Y2)}>{Y1 / a+2×(X1-X2)}.

[0103] Furthermore, as a common modification of the first and second embodiments, for example, the storage box 1B may store other items instead of the tape cassette 8. The other items are, for example, consumables used for printing, such as ink tanks, ink cartridges, or ink ribbon cassettes. The other items may also be consumables used for purposes other than printing. The other items do not have to be consumables, and may be food, etc. The header 3 of the storage boxes 1A, 1B may be absent, or may be constituted by either the header piece 31 or 32. The bottom wall 4 of the storage boxes 1A, 1B is not limited to the shape of a bottom, and may be, for example, the shape of a so-called caramel box.

[0104] In the second embodiment, the storage box 1B is an example of a "storage box" in the second aspect of the present invention. The tape cassette 8 is an example of a "printing cassette" in the second aspect of the present invention. The printing tape 89 is an example of a "tape" in the second aspect of the present invention.
