The gist of the cassette of the sixteenth invention is that in any one of the first to fifteenth inventions, the diameter of the opening of the hole becomes smaller as it goes from the one side to the other side. The reason is that it has an inclined surface that slopes like this.

According to the cassette of the first invention, (a) the pressed portion overlaps a convex envelope defined by the plurality of supported portions in the first direction, and in the first direction, the pressed portion overlaps the convex envelope defined by the plurality of supported portions; The tape roll is located on the other side from the one end, and (b) the tape roll is wound around the hole with the first direction as a winding center. Since the pressed portion is provided inside the hole around which the tape roll is wound, interference with the built-in items housed inside the cassette is avoided, and the projected area of the cassette in the first direction is increased. suppressed. Further, since the pressed portion overlaps the convex envelope defined by the supported portion in the first direction, the cassette can be stably mounted even with one pressed portion.

According to the cassette of the second invention, (a) a support wall is provided that supports the tape roll from the other side and extends in a direction perpendicular to the first direction, and (b) the pressed portion is provided at a portion of the support wall that faces the presser member of the printing device. Thereby, even if the pressed portion is pressed by the presser member of the printing device, the pressing force of the presser member is not directly applied to the upper wall having the upper surface, so deformation of the upper wall is suppressed. Since the deformation of the top wall is suppressed, an increase in tape drawing resistance due to contact between the top wall and the tape is suppressed.

According to the cassette of the third aspect of the invention, the pressed portion is provided at a protruding portion of the support wall that protrudes toward the one side from a support surface that supports the tape roll. Since the pressed portion is provided on the protruding portion that protrudes from the support wall to one side, the positioning accuracy in the first direction of the pressed portion with respect to the presser member of the printing device is improved. This allows the cassette to be mounted while being stably pressed.

According to the cassette of the fourth invention, (a) the cassette case includes (a1) a first layer provided with the tape roll; (a2) partitioned from the first layer by the support wall; (b) the cassette includes (b1) a defining wall that defines the other side of the second layer; and (b2) the pressed portion. A first support part is provided that extends in the first direction between the other side and the regulation wall and supports the pressed part at a position overlapping the hole part in the first direction. The pressed portion is supported by the support wall and also supported by the defining wall via the first support portion. Since the pressed portion is supported by the support wall and the regulation wall, the pressed portion is unlikely to deform to the other side in the first direction even if pressed by the presser member of the printing device. Therefore, the cassette can be mounted while being stably pressed by the presser member of the printing device.

According to the cassette of the fifth invention, the first support portion extends from the other side surface of the support wall toward the other side. In this way, since the first support part is provided integrally with the support wall, the presser member of the printing device that the pressed part receives is more effective than when the first support part is provided as a separate member from the support wall. This makes it easier to distribute the pressing force to the specified wall. Therefore, even when pressed by the presser member of the printing device, the pressed portion is less likely to deform to the other side in the first direction, and the cassette can be mounted in a stably pressed state.

According to the cassette of the sixth aspect of the invention, a bottom wall extending in a direction perpendicular to the first direction is provided, and (a) the cassette case is partitioned from the second layer by the (a1) defining wall. (a2) a third layer located on the other side of the second layer; (b) the other side of the third layer is defined by the bottom wall; (c) the cassette has a third layer located on the other side of the second layer; A second support part is provided that extends in the first direction between the regulation wall and the bottom wall and supports the regulation wall at a position overlapping the hole part in the first direction. The pressed portion is supported by the support wall and the regulation wall, and is also supported by the bottom wall via the second support portion. Since the pressed portion is supported by the support wall, the regulation wall, and the bottom wall, the pressed portion is unlikely to deform to the other side in the first direction even if pressed by the presser member of the printing device. Therefore, the cassette can be mounted while being stably pressed.

According to the cassette of the seventh invention, the second support portion extends from the other side surface of the regulation wall toward the other side. In this way, since the second support part is provided integrally with the regulation wall, the pressure of the presser member of the printing device that the regulation wall receives is smaller than when the second support part is provided as a separate member from the regulation wall. It becomes easier to disperse the pressing force to the bottom wall. Therefore, even when pressed by the presser member of the printing device, the pressed portion is less likely to deform to the other side in the first direction, and the cassette can be mounted in a stably pressed state.

According to the cassette of the eighth aspect of the invention, the support wall and the regulation wall are connected to each other at a position different from the first support part in the orthogonal direction, and the regulation wall is connected to the support wall in the orthogonal direction. A regulation department is provided to regulate the movement of people. By providing the regulating portion, relative movement between the support wall and the regulation wall in the orthogonal direction is regulated, and thus movement of the first support portion with respect to the regulation wall in the orthogonal direction is regulated. Therefore, the pressed portion is reliably supported by the first support portion.

According to the cassette of the ninth invention, (a) a hole wall portion forming a part of the hole portion and extending from the one side toward the other side is provided, and (b) the pressed portion extends from the hole wall toward the inside of the hole in a direction orthogonal to the first direction. The portion extending from the top surface toward the inside of the hole extending toward the other side in the first direction is the pressed portion. Since the pressed portion is provided integrally with the hole wall extending from the top surface, the positioning accuracy of the pressed portion in the first direction with respect to the presser member of the printing device is improved. Further, unlike the case where the hole wall portion and the pressed portion are provided in separate case members, it is not necessary to align the positions of the hole wall portion and the pressed portion in the orthogonal direction.

According to the cassette of the tenth aspect, (a1) a support wall that supports the tape roll from the other side and extends in the orthogonal direction; and (a2) a support wall that supports the pressed portion from the other side. The third support part is provided in the support wall at a position overlapping the hole part in the first direction. A third support part that supports the pressed part is provided on the support wall. Therefore, since the pressed portion is supported by the upper wall having the upper surface and the support wall, the pressed portion is less likely to deform to the other side in the first direction even when pressed by the presser member of the printing device. Therefore, the cassette can be mounted while being stably pressed.

According to the cassette of the eleventh invention, the third support portion protrudes toward the one side from a support surface of the support wall that supports the tape roll. In this manner, since the third support portion protrudes from the support wall to one side and supports the pressed portion, the positioning accuracy in the first direction of the pressed portion with respect to the presser member of the printing device is improved. This allows the cassette to be mounted while being stably pressed.

According to the cassette of the twelfth aspect, in the first direction, the distance of the gap between the other side end of the pressed part and the one side end of the third support part is such that the gap has the upper surface. It is smaller than the distance of the gap between the upper wall and the tape roll facing the upper wall. With this, when the top wall is deformed toward the other side in the first direction due to the pressing force of the presser member of the printing device, the pressed portion contacts the support wall that supports the tape before the top wall and the tape come into contact. That is, when the upper wall and the tape are about to come into contact, the pressed portion is supported by the support wall. Therefore, an increase in tape pull-out resistance due to contact between the top wall and the tape due to deformation of the top wall toward the other side in the first direction is suppressed.

According to the cassette of the thirteenth aspect, (a) the cassette case includes (a1) a first layer provided with the tape roll; (a2) partitioned from the first layer by the support wall; a second layer located on the other side of the layers; (b) the cassette includes (b1) a defining wall defining the other side of the second layer; and (b2) supporting the support wall. The fourth support part is provided in the second layer and extends in the first direction at a position overlapping with the hole part in the first direction. The pressed portion is supported by the third support portion of the support wall, and is also supported by the defining wall via the fourth support portion. Since the pressed portion is supported by the support wall and the regulation wall, the pressed portion is unlikely to deform to the other side in the first direction even if pressed by the presser member of the printing device. Therefore, the cassette can be mounted while being stably pressed.

According to the cassette of the fourteenth aspect of the invention, the cassette case is provided with a bottom wall extending in a direction orthogonal to the first direction, and (a) the cassette case is partitioned from the second layer by the defining wall; (b) the other side of the third layer is defined by the bottom wall; and (c) the cassette has a third layer located on the other side of the second layer; and a fifth support part that extends in the first direction between the fifth support part and supports the regulation wall at a position overlapping the hole part in the first direction. The pressed portion is supported by the support wall and the regulation wall, and is also supported by the bottom wall via the fifth support portion. Since the pressed portion is supported by the support wall, the regulation wall, and the bottom wall, the pressed portion is unlikely to deform to the other side in the first direction even if pressed by the presser member of the printing device. Therefore, the cassette can be mounted while being stably pressed.

According to the cassette of the fifteenth aspect of the invention, (a) the tape roll is configured by winding the tape around a cylindrical tape spool, and (b) the pressed portion is configured such that (b1) the first direction and (b2) located inside the tape spool in orthogonal directions; (b2) located on the other side from the one end of the tape spool in the first direction; and (b2) located on the other side of the tape spool in the first direction. It is located on the one side from the end. In this way, since the pressed part is located inside the tape spool around which the tape of the tape roll is wound, interference with the built-in contents housed inside the cassette is avoided, and the projection in the first direction of the cassette is avoided. Increase in area is suppressed.

According to the cassette of the sixteenth invention, the opening of the hole is provided with an inclined surface that slopes so that the diameter of the hole decreases from the one side toward the other side. When the presser member of the printing device is inserted into the hole, the presser member is smoothly guided into the hole because the opening of the hole is provided with an inclined surface.

In this way, in the vertical direction of the cassette 10, the supported parts 140, 142, and 144 provided at at least three locations are not necessarily at the same position. Note that the "bottom surface" of the cassette 10 in the present invention refers to the surface exposed on the back side of the cassette 10, and the supported parts 140, 142, and 144 are provided on the bottom surface.

The main body cover 122 is provided with a presser member 124 that protrudes downward. The first case member 12 has a hole 33 extending downward from the front surface 12a1 of the upper wall 12a into which the presser member 124 is inserted when the cassette 10 is attached to the printing device 102 and the main body cover 122 is closed. is provided. The cylindrical first support protrusion 30 described above is a hole wall part that constitutes a part of the hole part 33 extending downward from the front surface 12a1 of the upper wall 12a, and The part is the hole part 33. An opening provided at the upper end of the hole 33 is provided with an inclined surface 31 in which the diameter of the hole 33 decreases from the upper side toward the lower side. A pressed portion 48 is provided inside the hole 33 and is pressed from above by the presser member 124 inserted. As shown in FIG. 17A, for example, in the vertical direction, the upper end of the second support protrusion 32 is closed in a disc shape, and the lower end of the second support protrusion 32 is open. The pressed portion 48 is a disk-shaped flat surface at the upper end of the second support protrusion 32 . The center of winding of the printing tape roll 26 is the first rotation center line C1 in the vertical direction, and the printing tape roll 26 is arranged so as to be wound around the hole 33. As a result, the cassette 10 is sandwiched in the vertical direction by the pressing member 124 and the three cassette support parts 130, 132, and 134, so that the cassette 10 is fixed so as not to move in the vertical direction.

As shown in FIG. 17(b), a convex envelope (line) 146 is defined by at least three supported parts 140, 142, and 144. The convex envelope 146 is an area formed by connecting the supported parts 140, 142, and 144 when viewed in the vertical direction. The pressed portion 48 overlaps the convex envelope 146 in the vertical direction. In this way, the pressed portion 48 is provided within the convex envelope 146 in the orthogonal direction perpendicular to the up-down direction. Therefore, if the cassette 10 is pressed at at least one point within the convex envelope 146 in the orthogonal direction, the cassette 10 can be stably mounted.

As shown in FIG. 17(a), the second case member 14 supports the printing tape roll 26 from below and includes a support wall 14a extending in a direction perpendicular to the up-down direction. In the orthogonal direction, the pressed portion 48 is provided at a portion of the support wall 14 a that faces the presser member 124 and is located inside the printing tape spool 24 . The pressed portion 48 is provided on the second support protrusion 32 that protrudes above the support surface that supports the printing tape roll 26 of the support wall 14a. In the vertical direction, the pressed portion 48 is located below the upper end of the printing tape spool 24 and above the lower end of the printing tape spool 24 .

The cassette case 19 has a first space S1 in which the printing tape roll 26 is provided, and a second space S2 that is separated from the first space S1 by the support wall 14a and located below the first space S1. The third case member 16 includes a defining wall 16a that defines the lower side of the second space S2. As shown in FIG. 9, the second case member 14 includes a first support portion 35A that extends in the vertical direction between the lower side of the pressed portion 48 and the regulation wall 16a and supports the pressed portion 48. . The first support portion 35A has, for example, a cylindrical shape, extends downward from the back surface of the support wall 14a, and has a lower end in contact with the regulation wall 16a of the third case member 16. Note that the second space S2 corresponds to the "second layer" in the present invention.

As shown in FIG. 10, a locking claw 27a that projects upward is provided on the front surface of the defining wall 16a of the third case member 16. As shown in FIG. 9, a fixing claw 28a that protrudes downward is provided on the back surface of the support wall 14a of the second case member 14. In the orthogonal direction, the locking pawl 27a and the fixing pawl 28a are at the same position and at a different position from the first support portion 35A. In the orthogonal direction, a through hole 58 is provided between the locking claw 27a and the short side portion 46a and long side portion 46b of the outer peripheral wall 46. That is, the locking pawl 27a is provided at a corner of the defining wall 16a where the defining wall 16a is not directly connected to either the short side 46a or the long side 46b of the outer peripheral wall 46. In the orthogonal direction, a through hole 52 is provided between the fixing claw 28a and the short side portion 44a and long side portion 44b of the outer peripheral wall 44. That is, the fixing claws 28a are provided at corners of the support wall 14a where the support wall 14a is not directly connected to either the short side 44a or the long side 44b of the outer peripheral wall 44.

The locking pawl 27a includes a columnar part that stands up from the regulation wall 16a in the shape of a rectangular parallelepiped, and a pawl part provided at the tip of the columnar part. The fixed claw 28a has a groove portion of a predetermined width into which at least a portion of the columnar portion of the locking claw 27a is fitted in the engaged state, and a groove portion provided at the tip of the groove portion to engage with a claw portion of the locking claw 27a. It has a fixed part. When the locking claw 27a and the fixed claw 28a are engaged, the columnar part of the locking claw 27a and the groove part of the fixed claw 28a are fitted together. In this fitted state, the support wall 14a and the regulation wall 16a become difficult to move relative to each other in any orthogonal direction. In this way, when the locking claw 27a and the fixing claw 28a are engaged, the corner of the support wall 14a and the corner of the regulation wall 16a described above are connected, and the regulation wall 16a is moved in the direction orthogonal to the support wall 14a. The relative movement of is regulated. The locking claw 27a and the fixing claw 28a correspond to the "restriction part" in the present invention.

The cassette case 19 has a third space S3 that is separated from the second space S2 by the defining wall 16a and located below the second space S2. The lower side of the third space S3 is defined by the bottom wall 18a.

As shown in FIG. 11, the third case member 16 includes a second support portion 35B extending in the vertical direction between the regulation wall 16a and the bottom wall 18a. The second support portion 35B has a cylindrical shape, for example. In addition, in FIG. 17(a), the shape is simplified and illustrated as a cylinder. In the vertical direction, the area A2 where the second support part 35B is provided overlaps with the area A1 where the hole part 33 is provided. That is, the second support portion 35B extends vertically between the defining wall 16a and the bottom wall 18a, and supports the defining wall 16a at a position overlapping the hole portion 33 in the vertical direction. The second support portion 35B extends downward from the back surface of the regulation wall 16a, and its lower end is in contact with the front surface 18a1 of the bottom wall 18a of the fourth case member 18.

According to the cassette 10 of the present embodiment, (a) the pressed portion 48 overlaps the convex envelope 146 defined by the three supported portions 140, 142, 144 in the vertical direction, and prints in the vertical direction. It is located below the upper end of the tape roll 26. (b) The printing tape roll 26 is arranged so as to be wound around the hole 33 with the first rotation center line C1 in the vertical direction as the winding center. Since the pressed portion 48 is provided inside the hole 33 around which the printing tape roll 26 is wound, interference of the pressed portion 48 with the built-in contents housed inside the cassette 10 is avoided. An increase in the projected area of the cassette 10 in the vertical direction is suppressed. Further, since the pressed portion 48 overlaps in the vertical direction with the convex envelope 146 defined by the supported portions 140, 142, and 144, the cassette 10 can be stably mounted even with one pressed portion 48.

According to the cassette 10 of the present embodiment, (a) the support wall 14a that supports the printing tape roll 26 from below and extends in the orthogonal direction orthogonal to the up-down direction is provided, and (b) the pressed portion 48 is provided at a portion of the support wall 14a that faces the presser member 124 of the printing device 102. As a result, even if the pressed portion 48 is pressed by the presser member 124 of the printing device 102, the pressing force of the presser member 124 is not directly applied to the upper wall 12a having the front surface 12a1, so deformation of the upper wall 12a is suppressed. . Since the deformation of the top wall 12a is suppressed, an increase in tape drawing resistance due to contact between the top wall 12a and the printed tape 22 is suppressed.

According to the cassette 10 of the present embodiment, the pressed portion 48 is provided on the second support protrusion 32, which is a protrusion of the support wall 14a that protrudes above the support surface that supports the printing tape roll 26. . Since the pressed portion 48 is provided on the protruding portion that protrudes upward from the support wall 14a, the positioning accuracy of the pressed portion 48 in the vertical direction with respect to the presser member 124 of the printing device 102 is improved. This allows the cassette 10 to be mounted in a stably pressed state.

According to the cassette 10 of the present embodiment, (a) the cassette case 19 is partitioned into (a1) the first space S1 in which the printing tape roll 26 is provided, and (a2) the first space S1 by the support wall 14a, It has a second space S2 located below the first space S1. (b) The cassette 10 extends in the vertical direction between (b1) a defining wall 16a that defines the lower side of the second space S2, and (b2) the lower side of the pressed portion 48 and the defining wall 16a, A first support portion 35A that supports the pressed portion 48 at a position vertically overlapping the hole portion 33 is provided. The pressed portion 48 is supported by the support wall 14a and also supported by the regulation wall 16a via the first support portion 35A. Since the pressed portion 48 is supported by the support wall 14a and the regulation wall 16a, the pressed portion 48 is difficult to deform downward in the vertical direction even when pressed by the presser member 124 of the printing device 102. Therefore, the cassette 10 can be mounted while being stably pressed by the pressing member 124 of the printing device 102.

According to the cassette 10 of this embodiment, the first support portion 35A extends downward from the back surface of the support wall 14a. In this way, since the first support part 35A is provided integrally with the support wall 14a, the pressed part 48 receives less support compared to the case where the first support part 35A is provided as a separate member from the support wall 14a. The pressing force of the presser member 124 of the printing device 102 can be easily distributed to the defining wall 16a. Therefore, even when pressed by the presser member 124 of the printing device 102, the pressed portion 48 is less likely to deform downward in the vertical direction, and the cassette 10 can be mounted in a stably pressed state.

According to the cassette 10 of the present embodiment, the bottom wall 18a extends in the orthogonal direction orthogonal to the up-down direction, and (a) the cassette case 19 of the cassette 10 is connected to the second space by the (a1) regulation wall 16a. S2, (a2) has a third space S3 located below the second space S2, (b) the lower side of the third space S3 is defined by the bottom wall 18a, and (c) the cassette 10 is , a second support part 35B is provided that extends vertically between the regulation wall 16a and the bottom wall 18a and supports the regulation wall 16a at a position overlapping the hole part 33 in the vertical direction. The pressed portion 48 is supported by the support wall 14a and the regulation wall 16a, and is also supported by the bottom wall 18a via the second support portion 35B. Since the pressed portion 48 is supported by the support wall 14a, the regulation wall 16a, and the bottom wall 18a, the pressed portion 48 is difficult to deform downward in the vertical direction even when pressed by the presser member 124 of the printing device 102. . Therefore, the cassette 10 can be mounted while being stably pressed.

According to the cassette 10 of this embodiment, the second support portion 35B extends downward from the back surface of the regulation wall 16a. In this way, since the second support part 35B is provided integrally with the regulation wall 16a, the printing that the regulation wall 16a receives is less likely than in the case where the second support part 35B is provided as a separate member from the regulation wall 16a. The pressing force of the presser member 124 of the device 102 is easily distributed to the bottom wall 18a. Therefore, even when pressed by the presser member 124 of the printing device 102, the pressed portion 48 is less likely to deform downward in the vertical direction, and the cassette 10 can be mounted in a stably pressed state.

According to the cassette 10 of the present embodiment, the support wall 14a and the regulation wall 16a are connected to each other at a position different from the first support part 35A in the orthogonal direction, and the regulation wall 16a is connected to the support wall 14a relative to the orthogonal direction. A locking claw 27a and a fixing claw 28a are provided to restrict movement.

A pressed portion 48C is provided in the first case member 12.

The pressed portion 48C, which is provided inside the hole portion 33 and is pressed from above by the presser member 124 to be inserted, extends from the lower end of the first support protrusion 30 to the hole portion in an orthogonal direction perpendicular to the up-down direction. 33, extending inward in the radial direction around the first rotation center line C1, which is the center of the rotation center line C1. In this embodiment, since the second support protrusion 32 and the first support part 35A in the first embodiment are not provided, there is a distance L2 between the lower end of the pressed part 48C and the support wall 14a in the vertical direction. There is a gap of [mm]. In the vertical direction, the distance L1 [mm] of the gap between the top wall 12a having the front surface 12a1 and the printing tape roll 26 facing the top wall 12a is smaller than the distance L2.

FIG. 21 is a diagram illustrating the cross-sectional structure of the cassette 10D and the mounting of the cassette 10D on the cassette mounting section 104 provided in the printing device 102 according to the fifth embodiment of the present invention. The configuration of the cassette 10D according to the fifth embodiment is substantially the same as the configuration of the cassette 10C according to the fourth embodiment described above, but unlike the cassette 10C, the third support part 35C, the fourth support part 35D, and the fifth support part A section 35E is provided.

As shown in FIG. 21, the second case member 14 includes a third support portion 35C that extends in the vertical direction between the lower side of the pressed portion 48C and the support wall 14a and supports the pressed portion 48C. . The third support portion 35C has a cylindrical shape, for example. The third support portion 35C protrudes above the support surface of the support wall 14a that supports the printing tape roll 26. In the vertical direction, the area A3 where the third support part 35C is provided overlaps with the area A1 where the hole part 33 is provided. That is, the third support portion 35C supports the pressed portion 48C at a position that extends in the vertical direction between the lower side of the pressed portion 48C and the support wall 14a and overlaps the hole portion 33 in the vertical direction. . The third support portion 35C extends upward from the upper surface of the support wall 14a. In the vertical direction, the distance L3 [mm] of the gap between the lower end of the pressed part 48C and the upper end of the third support part 35C is the distance L3 [mm] between the upper wall 12a having the front surface 12a1 and the upper wall 12a facing the upper wall 12a. The distance L1 between the printing tape roll 26 and the printing tape roll 26 is smaller than the gap distance L1. Note that if there is an inclusion between the lower end of the pressed part 48C and the upper end of the third support part 35C, the gap distance L3 is It is the distance between the upper end of the third supporting part 35C minus the thickness in the vertical direction of the inclusion interposed between them.

The second case member 14 includes a fourth support portion 35D extending vertically between the support wall 14a and the regulation wall 16a. The fourth support portion 35D has a cylindrical shape, for example. In the vertical direction, the area A4 where the fourth support part 35D is provided overlaps with the area A1 where the hole part 33 is provided. That is, the fourth support portion 35D supports the support wall 14a at a position that extends in the vertical direction between the support wall 14a and the regulation wall 16a and overlaps the hole portion 33 in the vertical direction. The fourth support portion 35D extends downward from the back surface of the support wall 14a.

The third case member 16 includes a fifth support portion 35E extending vertically between the regulation wall 16a and the bottom wall 18a. The fifth support portion 35E has a cylindrical shape, for example, like the second support portion 35B described above. In addition, in FIG. 21, the shape is simplified and shown as a cylinder. In the vertical direction, the area A5 where the fifth support part 35E is provided overlaps with the area A1 where the hole part 33 is provided. That is, the fifth support portion 35E extends vertically between the defining wall 16a and the bottom wall 18a, and supports the defining wall 16a at a position overlapping the hole portion 33 in the vertical direction. The fifth support portion 35E extends downward from the back surface of the regulation wall 16a.

FIG. 22 is a diagram illustrating the deformation of the cassette case 19 due to the pressing of the pressed portion 48C of the cassette 10C according to the fourth embodiment. In the cassette 10C, in the vertical direction, the distance between the gap between the top wall 12a having the front surface 12a1 and the printing tape roll 26 facing the top wall 12a, that is, the gap between the back surface 12a2 and the upper end of the printing tape roll 26. The distance L1 is smaller than the distance L2 of the gap between the lower end of the pressed portion 48C and the support wall 14a. Therefore, when the first case member 12 is molded from a resin that is easily deformed and the upper wall 12a is deformed downward in the vertical direction due to the pressing force of the presser member 124 of the printing device 102, the pressed portion 48C is pressed against the printing tape. There is a possibility that the back surface 12a2 of the top wall 12a and the printing tape 22 may come into contact with each other before the printing tape 22 comes into contact with the support wall 14a that supports the printing tape 22. When the back surface 12a2 of the upper wall 12a and the printing tape 22 come into contact, the tape drawing resistance of the printing tape 22 increases. On the other hand, in the cassette 10C of this embodiment, the increase in tape pull-out resistance of the printing tape 22 is suppressed, as will be described later.

According to the cassette 10D of this embodiment, the same effects as the cassette 10C of the fourth embodiment described above are achieved.

According to the cassette 10D of the present embodiment, (a1) the support wall 14a that supports the printing tape roll 26 from below and extends in the orthogonal direction; and (a2) the support wall 14a that supports the pressed portion 48C from below. A third support portion 35C is provided in the support wall 14a at a position overlapping the hole portion 33 in the vertical direction. Since the third support portion 35C that supports the pressed portion 48C is provided on the support wall 14a, the pressed portion 48C is supported by the upper wall 12a having the front surface 12a1 and the support wall 14a, so that the presser foot of the printing device 102 Even when pressed by the member 124, the pressed portion 48C is less likely to deform downward in the vertical direction. Therefore, the cassette 10D can be mounted in a stably pressed state.

According to the cassette 10D of this embodiment, the third support portion 35C protrudes above the support surface of the support wall 14a that supports the printing tape roll 26. In this way, since the third support portion 35C protrudes upward from the support wall 14a and supports the pressed portion 48C, the positioning accuracy in the vertical direction of the pressed portion 48C with respect to the presser member 124 of the printing device 102 is improved. . This allows the cassette 10D to be mounted in a stably pressed state.

According to the cassette 10D of the present embodiment, in the vertical direction, the distance L2 of the gap between the lower end of the pressed portion 48C and the upper end of the third support portion 35C is the upper wall 12a having the front surface 12a1. and the printing tape roll 26 facing the upper wall 12a. As a result, when the upper wall 12a is deformed downward in the vertical direction due to the pressing force of the presser member 124 of the printing device 102, the pressed portion 48C is printed before the back surface 12a2 of the upper wall 12a and the printing tape 22 come into contact with each other. It comes into contact with a third support portion 35C provided on the support wall 14a that supports the tape 22. That is, when the upper wall 12a and the printing tape 22 are about to come into contact, the pressed portion 48C is supported by the support wall 14a. Therefore, an increase in tape pull-out resistance due to contact between the top wall 12a and the printing tape 22 due to downward deformation of the top wall 12a in the vertical direction is suppressed.

According to the cassette 10D of this embodiment, (a) the cassette case 19 of the cassette 10D is divided into (a1) the first space S1 in which the printing tape roll 26 is provided, and (a2) the first space S1 by the support wall 14a. (b) The cassette 10D includes (b1) a defining wall 16a that defines the lower side of the second space S2, and (b2 ) A fourth support part 35D that supports the support wall 14a and extends in the vertical direction at a position that vertically overlaps the hole part 33 in the second space S2 is provided. The pressed portion 48C is supported by the third support portion 35C of the support wall 14a, and is also supported by the regulation wall 16a via the fourth support portion 35D. Since the pressed portion 48C is supported by the support wall 14a and the regulation wall 16a, the pressed portion 48C is difficult to deform downward in the vertical direction even when pressed by the presser member 124 of the printing device 102. Therefore, the cassette 10D can be mounted in a stably pressed state.

According to the cassette 10D of the present embodiment, the bottom wall 18a extends in the orthogonal direction orthogonal to the up-down direction, and (a) the cassette case 19 of the cassette 10D is partitioned into the second space S2 by the regulation wall 16a. (b) The lower side of the third space S3 is defined by the bottom wall 18a, and (c) the cassette 10D has a third space S3 located below the second space S2. A fifth support portion 35E is provided that extends vertically between the wall 18a and supports the regulation wall 16a at a position overlapping the hole portion 33 in the vertical direction. The pressed portion 48C is supported by the support wall 14a and the regulation wall 16a, and is also supported by the bottom wall 18a via the fifth support portion 35E. Since the pressed portion 48C is supported by the support wall 14a, the regulation wall 16a, and the bottom wall 18a, the pressed portion 48C is difficult to deform downward in the vertical direction even when pressed by the presser member 124 of the printing device 102. . Therefore, the cassette 10D can be mounted in a stably pressed state.

Although the embodiments of the present invention have been described above in detail based on the drawings, the present invention is also applicable to other aspects.

In the first to fifth embodiments described above, the first support protrusion 30 constituting the hole wall is a wall that surrounds the entire circumferential direction of the hole 33, but the present invention is not limited to this. For example, the first support protrusion 30 may be configured such that a plurality of columns extending in the vertical direction surround a part of the hole 33 in the circumferential direction.

In the fifth embodiment described above, the third support section 35C, the fourth support section 35D, and the fifth support section 35E are provided, but the present invention is not limited to this. For example, the cassette 10D may be provided with the third support portion 35C, but not provided with the fourth support portion 35D and the fifth support portion 35E. In this embodiment, the pressed portion 48C is supported by the upper wall 12a and also supported by the support wall 14a via the third support portion 35C. Since the pressed portion 48C is supported by the upper wall 12a and the support wall 14a, the cassette 10D can be mounted in a stably pressed state compared to the aspect of the fourth embodiment described above. For example, the cassette 10D may be provided with a third support portion 35C and a fourth support portion 35D, but not provided with a fifth support portion 35E. In this embodiment, the pressed portion 48C is supported by the upper wall 12a and the support wall 14a, and is also supported by the defining wall 16a via the fourth support portion 35D. Since the pressed portion 48C is supported by the upper wall 12a, the support wall 14a, and the regulation wall 16a, the cassette 10D can be mounted in a stably pressed state compared to the above embodiment.

The first support part 35A, second support part 35B, third support part 35C, fourth support part 35D, and fifth support part 35E in the above-described embodiments 1, 2, and 5 are as shown in FIG. 23(a). Although it has a cylindrical shape or a cylindrical shape extending in the vertical direction, it is not limited thereto. For example, in addition to the cylindrical shape extending in the vertical direction shown in FIG. 23(a) and the cylindrical shape extending in the vertical direction shown in FIG. 23(b), the cross-shaped pillar shape shown in FIG. It's okay to have one. In the case of a cross-shaped columnar shape, even if a load is applied to each support part 35A, 35B, 35C, 35D, and 35E in the vertical direction by the presser member 124 via the pressed parts 48 and 48C, each support part 35A, 35B, 35C, 35D, and 35E are less prone to bending, that is, more resistant to buckling. Furthermore, when changing the conveyance direction of tapes such as the laminated tape 60 and the ink ribbon 68 using each of the supporting parts 35A, 35B, 35C, 35D, and 35E, each of the supporting parts 35A, 35B, 35C, 35D, and 35E When the tape has a cross-shaped columnar shape, the number of contact areas where the tape comes into contact with each of the supporting parts 35A, 35B, 35C, 35D, and 35E is smaller than in the case of a cylindrical or cylindrical shape, resulting in lower frictional resistance. This makes it possible to increase the size of the support parts 35A, 35B, 35C, 35D, and 35E in the orthogonal direction while suppressing an increase in the frictional resistance between the tape and each of the support parts 35A, 35B, 35C, 35D, and 35E. can. This makes it possible to further prevent the support parts 35A, 35B, 35C, 35D, and 35E from bending due to the load applied in the vertical direction via the pressed parts 48 and 48C.

In the first to fifth embodiments described above, the locking claws 27a and the fixing claws 28a, which are the regulating portions, are located at the corners of the regulation wall 16a and the support wall 14a where the regulation wall 16a and the support wall 14a are not directly connected to the outer peripheral wall. Although one location was provided in each department, it is not limited to this. For example, the locking claws 27a and the fixing claws 28a as regulating parts are provided at two locations in areas other than the corners of the regulation wall 16a and the support wall 14a where the regulation wall 16a and the support wall 14a are not directly connected to the outer peripheral wall. one regulating part regulates the relative movement of the regulation wall 16a and the support wall 14a in the left-right direction, and the other regulation part regulates the relative movement of the regulation wall 16a and the support wall 14a in the front-rear direction. It's okay to be.

For example, the supported parts 140, 142, and 144 may all be provided on the back surface 18a2 of the bottom wall 18a of the fourth case member 18. For example, all of the supported parts 140, 142, and 144 may be provided at a location other than the back surface 18a2 of the bottom wall 18a of the fourth case member 18.

In the first and second embodiments described above, the lower end of the first support part 35A was in contact with the regulation wall 16a of the third case member 16, but the lower end of the first support part 35A is in contact with the regulation wall 16a of the third case member 16. It may be slightly apart. Similarly, in the first embodiment, the lower end of the second support part 35B was in contact with the front surface 18a1 of the bottom wall 18a of the fourth case member 18, but the lower end of the second support part 35B is in contact with the bottom wall of the fourth case member 18. It may be slightly away from the front surface 18a1 of 18a.
