Description

[Technical Field]

[0001] The present invention relates to a printing cassette housing. [Background technology]

[0002] Patent Document 1 discloses a cassette tape case for storing cassette tapes. The cassette tape case has a flat portion that is the same size as the flat surface of the cassette tape, and a pair of first raised pieces are formed on the flat portion by cut lines. The pair of first raised pieces are combined with a pair of second raised pieces formed by cuts in a hub stop piece so that they press against each other, forming a hub stop. The hub stop is fitted into the hub hole of the cassette tape stored in the cassette tape case, preventing rotation of the reel and slack in the tape. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-258883 Summary of the Invention [Problem to be solved by the invention]

[0004] When removing the cassette tape from the cassette tape case, the first raised piece and the second raised piece press against each other, making it difficult to knock down the hub stopper, and the cassette tape is difficult to remove.

[0005] An object of the present invention is to provide a printing cassette storage box from which printing cassettes stored within the storage box can be easily removed. [Means for solving the problem]

[0006] According to one aspect of the present invention, there is provided a print cassette storage unit including a print cassette that is installed in a printing device and used for printing on print media, and a storage box that stores the print cassette, wherein the print cassette includes a case that stores the print media, and at least one recess formed on a specific surface that is one of the outer surfaces of the case, and the storage box includes an opening surface that is an outer surface that is opened when the case is opened, an opposing surface that is one of the outer surfaces connected to the opening surface and faces the specific surface of the case, and a recess that protrudes from the opposing surface into the storage box and is formed on the at least one recess of the case. and at least one protruding piece inserted into the recess, wherein all of the protruding pieces inserted into the recesses are formed by bending from an initial state constituting the opposing surface toward the inside of the storage box, and have a base end connected to the opposing surface and a free end extending from the base end and positioned inside the storage box, and are movable in a direction toward the initial state when the opening surface is opened to remove the printing cassette from the storage box, and in the initial state the free end of the protruding piece is located closer to the opening surface than the base end.

[0007] The printing cassette storage unit prevents the printing cassette from moving within the storage box by inserting a protruding piece on the storage box into a recess in the case of the printing cassette. When removing the printing cassette, the opening surface is opened and the printing cassette is removed from the storage box. At that time, the protruding piece returns to its initial state, so it does not interfere with removal of the printing cassette, making it easy to remove the printing cassette stored in the storage box.

[0008] In this aspect, the case of the print cassette may have a plurality of recesses, and the storage box may have a plurality of protruding pieces corresponding to the plurality of recesses. By positioning and holding the print cassette with the plurality of protruding pieces, the print cassette storage unit can prevent movement of the print cassette in the direction of a specific surface due to, for example, vibration during transport. Therefore, the print cassette storage unit can prevent relative friction between the print cassette and the storage box, and reduce the generation of paper dust.

[0009] In this aspect, the width of the widest part of the protruding piece may be equal to or greater than the inner diameter A of the recessed portion. Because the maximum width of the protruding piece is equal to or greater than the inner diameter A of the recessed portion, when the printing cassette is stored in the storage box, the printing cassette storage unit can position and hold the printing cassette within the storage box by fitting the protruding piece into the recessed portion, and can restrict movement of the printing cassette in the thickness direction.

[0010] In this aspect, the protruding piece has a base portion located on the base end side, and an insertion portion extending from the base portion toward the free end, and the width B1 of the protruding piece at the base portion may be greater than the width B2 of the protruding piece at the insertion portion and may be equal to or greater than the inner diameter A of the recess. Because the width B1 of the base portion is greater than the inner diameter A of the recess, when a printing cassette is stored in the storage box, the base portion fits into the recess, thereby positioning and holding the printing cassette within the storage box and restricting movement of the printing cassette in the thickness direction.

[0011] In this aspect, the insertion portion of the protruding piece has a guide portion at the end on the free end side that guides the insertion of the printing cassette into the recess, and the width B3 of the protruding piece at the guide portion may be smaller than the width B2 of the insertion portion excluding the guide portion, and smaller than the inner diameter A of the recess. Because the width B3 of the guide portion is smaller than the inner diameter A of the recess, when storing the printing cassette in the storage box of the printing cassette storage unit, first inserting the guide portion into the recess makes it easier to insert the protruding piece into the recess.

[0012] In this aspect, the storage box may be capable of storing multiple types of printing cassettes with different cassette thicknesses, which is the thickness of the printing cassette in a direction intersecting the specific surface, and the length between the base end and the free end of the protruding piece may be changeable to a length corresponding to the cassette thickness. Because the length of the protruding piece is variable, even when printing cassettes with different cassette thicknesses are stored in the same storage box, the printing cassette storage unit can position and hold the printing cassette within the storage box using the protruding piece.

[0013] In this aspect, a label may be affixed to the opposing surface of the storage box, covering at least the portion where the protruding piece is formed. By covering at least the portion where the protruding piece is formed with the label, the printing cassette storage unit can prevent foreign objects from entering the storage box through the portion where the protruding piece is formed.

[0014] In this aspect, information about the printing cassette housed in the storage box may be printed on the label. By printing information about the printing cassette on the label rather than on the storage box, the same storage box can be used even if different types of printing cassettes are housed in the storage box.

[0015] In this aspect, the protruding length X, which is the length between the base end and the free end of the protruding piece, may be longer in the direction toward the opening surface inside the storage box than the distance L between the printing cassette and the opening surface. Even if the position of the printing cassette is slightly shifted inside the storage box, the protruding piece will not come out of the recess.

[0016] In this aspect, the storage box has a back side that faces the opposing surface across the interior of the storage box, the printing cassette has an opposite side that is an outer surface opposite the specific surface in a direction intersecting the specific surface, some of the multiple recesses are provided on the opposite side, and some of the multiple protruding pieces are formed on the back side.The printing cassette storage unit can securely hold the printing cassette within the storage box by inserting the protruding pieces formed on the opposing surface and back side of the storage box into the recesses provided on the specific surface and the opposite surface of the printing cassette.

[0017] In this aspect, the storage box may have an index indicating the opening side. When removing a printing cassette from the storage box, the printing cassette storage unit guides the opening side by the index. This allows the protruding piece to return to its initial state when the printing cassette is removed, making it easier to remove the printing cassette without being obstructed by the protruding piece.

[0018] In this aspect, the printing cassette may include a take-up spool in the case that takes up the ink ribbon on which ink has been transferred to the print medium, and the recess may include an axial hole of the take-up spool. By inserting the protruding piece into the axial hole of the take-up spool, the printing cassette housing can suppress rotation of the take-up spool due to vibrations during transportation, for example.

[0019] In this aspect, the protruding piece may be formed on the opposing surface at a position corresponding to the position of the axial hole of the take-up spool on the specific surface. By inserting the protruding piece into the axial hole of the take-up spool, the printing cassette holder can suppress slack in the ink ribbon caused by rotation of the take-up spool due to vibrations during transportation, for example.

[0020] In this aspect, the print cassette may have an ejection port on an ejection surface, which is one of the outer surfaces of the case connected to the specific surface, for ejecting the print medium printed by the printing device to the outside of the case, and the print cassette may be stored inside the storage box with the ejection surface facing the closed surface, which is the surface on the opposite side of the storage box from the opening surface. When the print cassette is removed, the opening surface is opened, but because the ejection port is located on the closed surface opposite the opening surface, the print cassette storage unit can prevent the user from coming into contact with the ejection port.

[0022] An 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.

[0023] 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 in the printing device 10, regardless of whether the tape cassette 8 is installed in the printing device 10 or not. Furthermore, the orientation of the storage box 1, which will be described later, will be the orientation of the tape cassette 8 when it is stored in the storage box 1 (see FIG. 8). Note that in this embodiment, the up-down direction, for example, is used for convenience of explanation and is not limited to the vertical direction.

[0024] 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-rear 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-rear direction and are aligned with each other in the front-to-rear 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 bottom wall 85 and an top wall 86. 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. The lower wall 85 is provided with an outlet 88 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 lower wall 85 in the vertical direction, or slightly below.

[0025] 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 lower left corner 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 also 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.

[0026] 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 as the printing tape 89 travels 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 upper right section of the case 81, with both ends supported by the front wall 82 and the rear wall 83. The cylindrical hole in the take-up spool 87A is a cam hole 87B, in which a cam is formed to input a driving force for taking up 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.

[0027] 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 a rib-like structure that protrudes upward from approximately the center of the upper wall 86 and extends in the left-right direction, and is the structure that protrudes most upward on the upper wall 86. Both left and right ends of the protrusion 861 are formed as ribs that extend in the front-to-rear direction, and are H-shaped in plan view. The protrusion 851 is a rib-like structure that protrudes downward from approximately the center of the lower wall 85 and extends in the left-to-right direction, and is the structure that protrudes most downward on the lower wall 85. In other words, the protrusion 851 protrudes downward beyond the discharge port 88. Both left and right ends of the protrusion 851 are formed as ribs that extend in the front-to-rear direction, and are H-shaped in bottom view.

[0028] A recess 80 is formed in the left part of the case 81 in the vertical middle part, extending from the front wall 82 to the left 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.

[0029] 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 lower part 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 upper part 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 851 and 861 engage with the hooks 12 and 13, respectively, and the tape cassette 8 is positioned and held in place.

[0030] 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 the case 81 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 an ejection port 88. This creates a label with the image printed on the printing tape 89.

[0031] The storage box 1 will be described with reference to Figures 2 to 6. The storage box 1 is formed, for example, by assembling a backing board 100 as shown in Figure 6. The storage box 1 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.

[0032] 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. A label sticker 71 displaying information about the tape cassette 8 to be stored in the storage box 1, such as tape width, tape color, tape type, etc., is affixed to the front wall 61. 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. The lower end 611 of the front wall 61, the lower end 621 of the back wall 62, the lower end 631 of the left wall 63, and the lower end 641 of the right wall 64 form the peripheral edge 40 of the bottom wall 4 (see FIG. 3). The upper end 612 of the front wall 61, the upper end 622 of the back wall 62, the upper end 632 of the left wall 63, and the upper end 642 of the right wall 64 form the peripheral edge 50 of the top wall 5 (see FIG. 2).

[0033] 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.

[0034] 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.

[0035] 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 1, the storage boxes 1 may be inserted through the hole 30 onto a rod for hanging and displaying products, and the storage boxes 1 may be hung and displayed.

[0036] 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.

[0037] 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 the user places their finger when opening the storage box 1. An indicator 70 is formed on the male flap 51 to indicate the position of the opening 513. The indicator 70 indicates to the user that the top wall 5 is the opening surface for opening the storage box 1, for example, by pointing an arrow labeled "opening" at the opening 513. In this way, the indicator 70 guides the user to place their finger on the opening 513 to break the top wall 5 and open the storage box 1.

[0038] 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.

[0039] 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).

[0040] The insertion opening 521 is longer in the left-right direction than in the front-to-back 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-back direction between the front wall 61 and the rear wall 62, and is located near the rear wall 62. In this 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.

[0041] The left flap 53 is connected to an upper end 632 of the left wall 63 and extends rightward from the upper end 632 of the left wall 63. The right flap 54 is connected to an upper end 642 of the right wall 64 and extends leftward from the upper end 642 of the right wall 64. The left flap 53 and the right flap 54 are each rectangular and longer in the left-right direction than in the front-to-back direction, and are bilaterally symmetrical to each other. 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. 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 left-right length of each of the left flap 53 and the right flap 54 is smaller than the left-right distance between the left wall 63 and the right wall 64 and greater than half the left-right distance between the left wall 63 and the right wall 64. Therefore, one of the right end of the left flap 53 and the left end of the right flap 54 overlaps the other. In this embodiment, the left flap 53 overlaps the right flap 54.

[0042] Hereinafter, the layer formed by the male flaps 51 will be referred to as the "male flap layer 501." In this embodiment, the outer shape of the male flap layer 501 is determined by the outer shape of the male main body portion 515 in a planar view. The layer formed by the female flaps 52 will be referred to as the "female flap layer 502." In this embodiment, the outer shape of the female flap layer 502 is determined by the outer shape of the female flaps 52 in a planar view. The layer formed by the left flap 53 and the right flap 54 will be referred to as the "side flap layer 503." In this embodiment, 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 in a planar view.

[0043] 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 with the insertion opening 521 interposed therebetween. As shown in Fig. 4, the left flap 53 and the right flap 54 are provided with notches 531 and 541, respectively, so that the side flap layer 503 does not overlap with the insertion opening 521 in a plan view.

[0044] 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, and V14 indicate boundaries between adjacent components of the storage box 1. For example, imaginary line V0 indicates the boundary between the spine wall 62 and the header piece 31.

[0045] The backing sheet 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 backing sheet 100 is the side of the backing sheet 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 1 when the storage box 1 is assembled. The "front side" of the backing sheet 100 is the side of the backing sheet 100 shown in FIG. 6 that faces the front of the page, and is the side that faces the outside of the storage box 1 when the storage box 1 is assembled.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] In the top wall 5, the female flap 52 is disposed in the positive Y direction of the header piece 31 and is connected to the header piece 31. The male flap 51 is disposed in the positive Y direction of the front wall 61 and is connected to the front wall 61. An opening 513 is formed in the male flap 51, and an index 70 is printed on it. The left flap 53 is disposed in the positive Y direction of the left wall 63 and is connected to the left wall 63. The right flap 54 is disposed in the positive Y direction of the right wall 64 and is connected to the right wall 64.

[0050] Cutouts 75A and 76A are formed in the front wall 61. The cutout 75A is a cutout formed in positions in the positive X and positive Y directions from the center of the front wall 61. The cutout 76A is a cutout formed in positions in the negative X and negative Y directions from the center of the front wall 61. The cutouts 75A and 76A are generally U-shaped extending in the Y direction, and each cutout has a negative Y side and both the positive Y side and the X side cut in the thickness direction of the backing sheet 100, leaving only the negative Y side. The portions inside the cutouts 75A and 76A are protruding pieces 75 and 76, which are folded along the negative Y side for use. The negative Y side of the protruding pieces 75 and 76 is defined as base ends 755 and 765, and the positive Y side is defined as free ends 756 and 766. The base ends 755 and 765 are not separated from the front wall 61. In the initial state before being bent, the protruding pieces 75, 76 are located in the positive Y direction of the base ends 755, 765. That is, in the initial state, the protruding pieces 75, 76 have their free ends 756, 766 located in the positive Y direction of the base ends 755, 765, and form part of the front wall 61.

[0051] The protruding pieces 75, 76 have base portions 753, 763, insertion portions 752, 762, and guide portions 751, 761, respectively. The base portions 753, 763 extend in the Y positive direction from base ends 755, 765, respectively. The insertion portions 752, 762 extend from the base portions 753, 763 toward free ends 756, 766, respectively. The guide portions 751, 761 are the Y positive direction ends of the insertion portions 752, 762, respectively, and include the free ends 756, 766. The guide portions 751, 761 gradually narrow in the Y positive direction.

[0052] The width of the protruding pieces 75, 76 at the base portions 753, 763 is defined as width B1. The width of the protruding pieces 75, 76 at the portions of the insertion portions 752, 762 excluding the guide portions 751, 761 is defined as width B2. The width of the protruding pieces 75, 76 at the guide portions 751, 761 is defined as width B3. In this case, the width B1 of the base portions 753, 763 is larger than the width B2 of the insertion portions 752, 762 and is also larger than the width B3 of the guide portions 751, 761. In other words, the width B1 of the base portions 753, 763 is the largest at the protruding pieces 75, 76. As will be described later, when the storage box 1 is assembled and the tape cassette 8 is stored in the space 7, the protruding piece 75 is inserted into a cam hole 87B of a take-up spool 87A that opens in the front wall 82 of the tape cassette 8. Furthermore, the protruding piece 76 is inserted into the cylindrical hole 89B of the tape spool 89A. Here, the inner diameter of the cam hole 87B of the take-up spool 87A of the tape cassette 8 and the cylindrical hole 89B of the tape spool 89A is defined as inner diameter A (see FIG. 7). The width B1 of the protruding pieces 75, 76 at the base portions 753, 763 is larger than the inner diameter A of the cam hole 87B and the cylindrical hole 89B. Therefore, with the protruding pieces 75, 76 inserted into the cam hole 87B and the cylindrical hole 89B, the base portions 753, 763 function to position the tape cassette 8 and to prevent the take-up spool 87A and the tape spool 89A from rotating.

[0053] Next, the length of the protruding pieces 75, 76 in the Y direction is defined as the protruding length X of the protruding pieces 75, 76. Furthermore, the length of the front wall 61 in the Y direction is defined as L2. The length of the case 81 of the tape cassette 8 in the up-down direction is defined as L1 (see FIG. 7). Note that length L1 is the maximum length of the case 81 including the protrusions 851, 861. In this case, protruding length X is longer than the distance L obtained by subtracting length L1 from length L2. When the storage box 1 is assembled and the tape cassette 8 is stored in the space 7, the distance L obtained by subtracting the length L1 of the case 81 in the up-down direction from the length L2 of the front wall 61 is the maximum length of the gap between the top wall 5 and the case 81 when the case 81 of the tape cassette 8 abuts against the bottom wall 4. Since the projection length X is longer than the distance L, even if the tape cassette 8 moves up and down within the space 7, the projection pieces 75, 76 can be prevented from coming out of the cam hole 87B and the cylindrical hole 89B.

[0054] 6 to 8, a procedure for storing a tape cassette 8 in a storage box 1 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 this embodiment, creases are formed on the front surface of the mount 100 along the imaginary lines V0 to V14. On the other hand, no creases are formed on the back surface of the mount 100.

[0055] 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 margin 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.

[0056] 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.

[0057] 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 inward of 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).

[0058] Once the bottom wall 4 is formed, the box body 2 opens upward (see FIG. 3). The protruding pieces 75, 76 inside the cutouts 75A, 76A formed in the front wall 61 of the box body 2 are pushed inward. The protruding pieces 75, 76 have their free ends 756, 766 rotated around the base ends 755, 765 as axes and are positioned within the space 7. The free ends 756, 766 are positioned obliquely above and rearward of the base ends 755, 765, respectively.

[0059] As shown in Figure 7, in this state, 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 with the rear wall 83 facing the underside of the spine wall 62 of the storage box 1 from the front, and the bottom wall 85 facing the underside of the bottom wall 4 from above. In other words, the tape cassette 8 is stored in the storage box 1 with the ejection port 88 facing the bottom wall 4 of the storage box 1. The tape cassette 8 is moved downward relative to the storage box 1 while maintaining a gap between the front wall 82 of the case 81 and the underside of the front wall 61 of the storage box 1. The guide portions 751 and 761 of the protruding pieces 75 and 76 are inserted into the cam hole 87B of the take-up spool 87A and the cylindrical hole 89B of the tape spool 89A, respectively. Because the inner diameter A of cam hole 87B and cylindrical hole 89B is larger than the width B3 of guide portions 751, 761, guide portions 751, 761 are smoothly inserted into cam hole 87B and cylindrical hole 89B, respectively. While moving downward relative to storage box 1, tape cassette 8 is also moved slightly forward. This reduces the gap between the back surface of front wall 61 of storage box 1 and front wall 82 of case 81, and guide portions 751, 761 guide insertion portions 752, 762 into cam hole 87B and cylindrical hole 89B.

[0060] The width B1 of the base portions 753, 763 of the protruding pieces 75, 76 is larger than the inner diameter A of the cam hole 87B and the cylindrical hole 89B. Therefore, the base portions 753, 763 are pressed into the cam hole 87B and the cylindrical hole 89B. When the tape cassette 8 is stored in the storage box 1, the free ends 756, 766 of the protruding pieces 75, 76 are located rearward of the base ends 755, 765. Because the base portions 753, 763 of the protruding pieces 75, 76 are fitted into the cam hole 87B and the cylindrical hole 89B, the tape cassette 8 is positioned and held within the storage box 1. Furthermore, because the tape cassette 8 is positioned by the two protruding pieces 75, 76, it is also prevented from rotating within the space 7, for example, around one of the protruding pieces 75, 76 as an axis. The tape cassette 8 is positioned and held within the storage box 1 by the protruding pieces 75, 76, which prevents the tape cassette 8 from rubbing against the inner surface of the storage box 1 even when subjected to vibrations during transportation, etc. Therefore, the printing cassette storage unit 20 can prevent the generation of paper dust.

[0061] The backing sheet 100 is mountain-folded along imaginary line V9 and valley-folded along imaginary line V10. As a result, as shown in FIG. 8, the header 3 is formed, 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 imaginary lines V11 and V12. As a result, a side flap layer 503 composed of a left flap 53 and a right flap 54 is stacked on top of the female flap layer 502 on the top wall 5. Note that in the side flap layer 503, the left flap 53 and the right flap 54 may be stacked in any order. The backing sheet 100 is mountain-folded along imaginary line V13 and valley-folded along the perforation at the bottom end 571 of the base portion 57. As a result, the insertion portion 55 is formed.

[0062] The mount 100 is mountain-folded along the imaginary line V14. The insertion portion 55 is inserted inside the female flap 52 through the insertion opening 521. As a result, the male flap layer 501 is stacked on the side flap layer 503, and the top wall 5 shown in FIG. 2 is formed.

[0063] 2, a label sticker 71 is affixed to the front wall 61 of the storage box 1. The label sticker 71 covers the holes formed in the cutouts 75A, 76A by pushing in the protruding pieces 75, 76. This completes the assembly of the storage box 1 and the storage of the tape cassette 8 inside the storage box 1, completing the printing cassette storage unit 20.

[0064] When removing the tape cassette 8 from the storage box 1, the user follows the indicator 70 to hook their finger on the opening 513, break the top wall 5, and open the storage box 1. The ejection opening 88 of the tape cassette 8 is located in a position facing the bottom wall 4 of the storage box 1. Therefore, when the user inserts their finger into the storage box 1 with the top wall 5 opened and grabs the case 81 of the tape cassette 8 with their finger, they will not come into contact with the ejection opening 88 or the printing tape 89. The user pulls the tape cassette 8 upward from the storage box 1. At this time, as the tape cassette 8 moves upward, the free ends 756, 766 of the protruding pieces 75, 76 move above the base ends 755, 765. Therefore, the protruding pieces 75, 76 return to their initial states and do not interfere with the removal of the tape cassette 8.

[0065] As explained above, the printing cassette storage unit 20 prevents the tape cassette 8 from moving within the storage box 1 by inserting the protruding pieces 75, 76 of the storage box 1 into the cam hole 87B and cylindrical hole 89B of the case 81 of the tape cassette 8. When removing the tape cassette 8, the top wall 5 is opened and the tape cassette 8 is removed from the storage box 1. At that time, the protruding pieces 75, 76 return to their initial positions and do not interfere with the removal of the tape cassette 8, making it easy to remove the tape cassette 8 stored in the storage box 1 of the printing cassette storage unit 20.

[0066] By positioning and holding the tape cassette 8 with the two protruding pieces 75, 76, the printing cassette storage unit 20 can prevent the front wall 82 of the tape cassette 8 from moving in the planar direction (e.g., rotating) due to vibrations during transportation, for example. Therefore, the printing cassette storage unit 20 can prevent the tape cassette 8 and the storage box 1 from rubbing against each other, and prevent the generation of paper dust.

[0067] Since the maximum width of the protruding pieces 75, 76 is equal to or larger than the inner diameter A of the cam hole 87B and the cylindrical hole 89B, when the tape cassette 8 is stored in the storage box 1, the printing cassette storage body 20 positions and holds the tape cassette 8 within the storage box 1 by fitting the protruding pieces 75, 76 into the cam hole 87B and the cylindrical hole 89B, and can restrict movement of the tape cassette 8 in the thickness direction (front-to-back direction).

[0068] Since the width B1 of the base portions 753, 763 is larger than the inner diameter A of the cam hole 87B and the cylindrical hole 89B, when the tape cassette 8 is stored in the storage box 1, the printing cassette storage body 20 positions and holds the tape cassette 8 within the storage box 1 by fitting the base portions 753, 763 into the cam hole 87B and the cylindrical hole 89B, and can restrict movement of the tape cassette 8 in the thickness direction (front-to-back direction).

[0069] Since the width B3 of the guide portions 751, 761 is smaller than the inner diameter A of the cam hole 87B and the cylindrical hole 89B, when storing the tape cassette 8 in the storage box 1 of the printing cassette storage body 20, the guide portions 751, 761 are first inserted into the cam hole 87B and the cylindrical hole 89B, thereby making it easier to insert the protruding pieces 75, 76 into the cam hole 87B and the cylindrical hole 89B.

[0070] By covering at least the portions of the printing cassette container 20 where the protruding pieces 75, 76 are formed with the label sticker 71, it is possible to prevent foreign matter from entering the container box 1 through the positions where the protruding pieces 75, 76 are formed.

[0071] The printing cassette storage body 20 does not print information about the tape cassette 8 on the storage box 1 but prints it on a label sticker 71, so that the same storage box 1 can be used even when different types of tape cassettes 8 are stored in the storage box 1.

[0072] The protruding length X of the protruding pieces 75, 76 is longer than the distance L obtained by subtracting the vertical length L1 of the case 81 of the tape cassette 8 from the vertical length L2 of the front wall 61 of the storage box 1. Therefore, even if the position of the tape cassette 8 within the storage box 1 is slightly shifted, the protruding pieces 75, 76 will not come out of the cam hole 87B and the cylindrical hole 89B.

[0073] When the tape cassette 8 is removed from the storage box 1, the printing cassette storage body 20 guides the top wall 5 to be opened by the indicator 70. As a result, when the tape cassette 8 is removed, the protruding pieces 75, 76 are oriented to return to their initial state, so that the tape cassette 8 can be easily removed without being obstructed by the protruding pieces 75, 76.

[0074] By inserting the protruding pieces 75 and 76 into the cam holes 87B of the take-up spool 87A, the printing cassette container 20 can suppress rotation of the take-up spool 87A due to vibrations during transportation, for example.

[0075] By inserting the protruding pieces 75, 76 into the cam holes 87B of the take-up spool 87A, the printing cassette container 20 can prevent the ink ribbon from slackening due to rotation of the take-up spool caused by vibrations during transportation, for example.

[0076] When the tape cassette 8 is removed, the top wall 5 is opened, but the ejection port 88 is arranged on the bottom wall 4 opposite to the top wall 5, so the printing cassette storage body 20 can prevent the user from touching the ejection port 88.

[0077] In the above embodiment, the printing tape 89 is an example of a "printing medium" of the present invention. The front wall 82 is an example of a "specific surface" of the present invention. The cam hole 87B and the cylindrical hole 89B are examples of a "recess" of the present invention. The top wall 5 is an example of an "opening surface" of the present invention. The front wall 61 is an example of an "opposing surface" of the present invention. The space 7 of the storage box 1 is an example of the "interior" of the storage box of the present invention. The base portions 753 and 763 are an example of a "base portion" of the present invention. The insertion portions 752 and 762 are an example of an "insertion portion" of the present invention. The guide portions 751 and 761 are an example of a "guide portion" of the present invention. The label sticker 71 is an example of a "label" of the present invention. The spine wall 62 is an example of a "rear side surface" of the present invention. The rear wall 83 is an example of an "opposite surface" of the present invention. The cam hole 87B is an example of a "shaft hole" in claim 12 of the present invention. The bottom wall 85 is an example of an "ejection surface" of the present invention. The bottom wall 4 is an example of a "closing surface" of the present invention.

[0078] The present invention may be modified from the above embodiment. The various modified examples described below may be combined with each other as long as no contradictions arise. While the protruding pieces 75 and 76 are formed on the front wall 61 of the storage box 1, they may also be formed on the rear wall 62. The drive shaft of the printing device 10 is inserted into the take-up spool 87A and tape spool 89A of the tape cassette 8, which open into the front wall 82 and rear wall 83 of the case 81, respectively. Therefore, if the protruding pieces are provided on the rear wall 62 of the storage box 1, they can be inserted into the cam hole 87B of the take-up spool 87A and the cylindrical hole 89B of the tape spool 89A, which open into the rear wall 83 of the case 81. Configuring the printing cassette storage unit 20 in this way allows the tape cassette 8 to be more securely held within the storage box 1. Of course, either one of the protruding pieces 75 and 76 may be provided on the front wall 61 of the storage box 1, or three or more protruding pieces may be provided, not limited to two.

[0079] The protruding length X may be adjustable, as with protruding pieces 175, 176 shown in FIG. 9. FIG. 9(A) shows a state in which a tape cassette 108, which has a thinner front-to-rear thickness than the tape cassette 8, is stored in a storage box 101 provided with protruding pieces 175, 176 whose protruding length X is adjustable. There is a large gap between the front wall 82 of the tape cassette 108 and the rear surface of the front wall 61 of the storage box 101. When the protruding piece 175 is bent at its base into the space 7, a base portion 175C extending from the base end to approximately the center in the front-to-rear direction and a tip portion 175B extending from approximately the center in the front-to-rear direction to the free end extend in the front-to-rear direction without bending. The protruding piece 176 has a similar configuration. The protruding length X1 of the protruding pieces 175, 176 is longer than the thickness L3 of the storage box 101 minus the thickness L4 of the tape cassette 108. Therefore, the protruding pieces 175 and 176 can reach the cam hole 187B and the cylindrical hole 189B of the tape cassette 108 in the front-rear direction and can be inserted therein.

[0080] FIG. 9B shows a state in which the storage box 101 stores a tape cassette 208 that is thicker in the front-to-rear direction than the tape cassette 108. In this case, the gap between the front wall 82 of the tape cassette 208 and the rear surface of the front wall 61 of the storage box 101 is smaller than when the tape cassette 108 is stored. The length of the protruding piece 175 can be roughly halved by folding back the tip 175B toward the base 175C at approximately the center in the front-to-rear direction. The protruding piece 176 has a similar configuration. When the tip 175B is folded back, the protruding length X2 is shorter than the thickness L3 of the storage box 101 minus the thickness L4 of the tape cassette 108, but is longer than the thickness L3 minus the thickness L5 of the tape cassette 208. Therefore, the protruding pieces 175, 176 can reach the cam hole 287B and the cylindrical hole 289B of the tape cassette 208 in the front-to-rear direction and can be inserted into them, respectively.

[0081] In this way, by making the lengths of the protruding pieces 175, 176 variable, even if tape cassettes 108, 208 with different thicknesses in the front-to-rear direction (cassette thickness) are stored in the same storage box 101, the printing cassette storage unit 20 can position and hold the tape cassettes 108, 208 within the storage box 101 using the protruding pieces 175, 176. Note that the length of the protruding pieces 175, 176 may be changeable, for example, by cutting off the tip 175B.

[0082] The storage box 1 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.

[0083] Although the storage box 1 stores the tape cassettes 8 with the ejection opening 88 facing the bottom wall 4, the storage box 1 may store the tape cassettes 8 with the ejection opening 88 facing the top wall 5. In this case, the bottom wall 4 may serve as an opening, and an indicator 70 may be used to prompt the user to open the bottom wall 4. In this case, the protruding pieces 75, 76 may be configured so that, in the initial state, the free ends 756, 766 are positioned below the base ends 755, 765. The header 3 of the storage box 1 may be omitted, or may be configured with either the header pieces 31, 32. The bottom wall 4 of the storage box 1 is not limited to a bottom-bottom shape, and may be, for example, in the shape of a so-called caramel box.

[0084] The protruding pieces 75, 76 are inserted into the cam hole 87B and the cylindrical hole 89B of the tape cassette 8, but the holes to be inserted are not limited to holes that penetrate the tape cassette 8 in the thickness direction, such as the cam hole 87B and the cylindrical hole 89B, and may also be, for example, recesses.
