According to the cassette of the third invention, the pressed portion is provided on the protruding portion of the support wall that protrudes to one side of the support surface that supports the tape roll. Since the pressed portion is provided on the protruding portion protruding from the support wall to one side, the positioning accuracy of the pressed portion with respect to the pressing member of the printing device in the first direction is improved. As a result, the cassette can be mounted in a stable and pressed state.

According to the cassette of the fourth invention, (a) the cassette case is partitioned from the first layer provided with (a1) the tape roll and (a2) the first layer by the support wall, and the first layer is described. It has a second layer located on the other side of the layer, and (b) the cassette is of (b1) a defining wall defining the other side of the second layer and (b2) the pressed portion. It includes a first support portion that extends in the first direction between the other side and the defined wall and supports the pressed portion at a position that overlaps the hole portion in the first direction. The pressed portion is supported by the support wall and is also supported by the defined wall via the first support portion. Since the pressed portion is supported by the support wall and the specified wall, the pressed portion is less likely to be deformed to the other side in the first direction even when pressed by the pressing member of the printing apparatus. Therefore, the presser member of the printing device allows the cassette to be mounted in a stable and pressed state.

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 portion is provided integrally with the support wall, the presser member of the printing device received by the pressed portion is compared with the case where the first support portion is provided as a separate member from the support wall. It becomes easier to disperse the pressing pressure on the specified wall. Therefore, even if the pressed portion is pressed by the pressing member of the printing apparatus, the pressed portion is less likely to be deformed to the other side in the first direction, and the cassette can be mounted in a stable pressed state.

According to the cassette of the sixth invention, a bottom wall extending in an orthogonal direction orthogonal to the first direction is provided, and (a) the cassette case is (a1) partitioned from the second layer by the defined wall. (A2) has 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, and (c) the cassette is said.

The pressed portion is supported by the support wall and the specified 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 specified wall, and the bottom wall, the pressed portion is less likely to be deformed to the other side in the first direction even when pressed by the pressing member of the printing apparatus. Therefore, the cassette can be mounted in a stable and pressed state.

According to the cassette of the seventh invention, the second support portion extends from the other side surface of the defined wall toward the other side. In this way, since the second support portion is provided integrally with the specified wall, the pressing member of the printing device received by the specified wall is compared with the case where the second support portion is provided as a separate member from the specified wall. It becomes easier to disperse the pressing force on the bottom wall. Therefore, even if the pressed portion is pressed by the pressing member of the printing apparatus, the pressed portion is less likely to be deformed to the other side in the first direction, and the cassette can be mounted in a stable pressed state.

According to the cassette of the eighth invention, in the orthogonal direction, the support wall and the regulation wall are connected at a position different from that of the first support portion, and the regulation wall is relative to the support wall in the orthogonal direction. There is a regulatory department that regulates the movement of people. Since the regulation portion is provided, the relative movement of the support wall and the regulation wall in the orthogonal direction is restricted, so that the movement of the first support portion with respect to the regulation wall in the orthogonal direction is restricted. Therefore, the pressed portion is surely supported by the first supporting portion.

According to the cassette of the tenth invention, (a1) the tape roll is supported from the other side, and the support wall extending in the orthogonal direction and (a2) the pressed portion are supported from the other side. The three support portions include the hole portion and the third support portion provided at a position overlapping the hole portion in the support wall in the first direction. A third support portion that supports the pressed portion is provided on the support wall. Therefore, since the pressed portion is supported by the upper wall and the support wall having the upper surface, the pressed portion is less likely to be deformed to the other side in the first direction even when pressed by the pressing member of the printing apparatus. Therefore, the cassette can be mounted in a stable and pressed state.

According to the cassette of the eleventh invention, the third support portion projects to one side of the support wall from the support surface that supports the tape roll. In this way, since the third support portion projects from the support wall to one side to support the pressed portion, the positioning accuracy of the pressed portion with respect to the pressing member of the printing apparatus in the first direction is improved. As a result, the cassette can be mounted in a stable and pressed state.

According to the cassette of the twelfth invention, in the first direction, the distance between the other side end portion of the pressed portion and the one side end portion of the third support portion 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. As a result, when the upper wall is deformed to the other side in the first direction due to the pressing force of the pressing member of the printing device, the pressed portion comes into contact with the supporting wall supporting the tape before the upper wall and the tape come into contact with each other. That is, when the upper wall and the tape are about to come into contact with each other, the pressed portion is supported by the support wall. Therefore, an increase in tape pull-out resistance due to contact between the upper wall and the tape due to deformation of the upper wall to the other side in the first direction is suppressed.

According to the cassette of the thirteenth invention, (a) the cassette case is partitioned from (a1) the first layer provided with the tape roll and (a2) the first layer by the support wall, and the first layer is described. A second layer located on the other side of the layer is provided, and (b) the cassette supports (b1) a defining wall defining the other side of the second layer and (b2) the supporting wall. The second support portion includes the hole portion and the fourth support portion extending in the first direction at a position overlapping the hole portion in the first direction. The pressed portion is supported by the third support portion of the support wall and also by the defined wall via the fourth support portion. Since the pressed portion is supported by the support wall and the specified wall, the pressed portion is less likely to be deformed to the other side in the first direction even when pressed by the pressing member of the printing apparatus. Therefore, the cassette can be mounted in a stable and pressed state.

According to the cassette of the fourteenth invention, a bottom wall extending in an orthogonal direction orthogonal to the first direction is provided, and (a) the cassette case is partitioned from the second layer by the defined wall, and the said. It has 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, and (c) the cassette is the defined wall and the bottom wall. A fifth support portion that extends in the first direction and supports the defined wall at a position that overlaps the hole portion in the first direction is provided. The pressed portion is supported by the support wall and the specified 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 specified wall, and the bottom wall, the pressed portion is less likely to be deformed to the other side in the first direction even when pressed by the pressing member of the printing apparatus. Therefore, the cassette can be mounted in a stable and pressed state.

According to the cassette of the fifteenth invention, (a) the tape roll is configured by winding the tape around a tubular tape spool, and (b) the pressed portion is (b1) in the first direction. It is located inside the tape spool in the orthogonal orthogonal direction, and (b2) is located on the other side of the tape spool on the other side of the tape spool in the first direction, and is located on the other side of the tape spool. It is located on one side of the end. In this way, since the pressed portion is located inside the tape spool around which the tape of the tape roll is wound, interference with the internal components housed inside the cassette is avoided and the projection in the first direction of the cassette is avoided. The 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 is inclined so that the diameter of the hole becomes smaller from one side to the other. When the presser member of the printing apparatus is inserted into the hole, the presser member is smoothly guided to the hole because the opening of the hole is provided with an inclined surface.

The second support portion 35B extends downward from the back surface of the defined 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 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 internal components housed inside the cassette 10 is avoided. The increase in the projected area in the vertical direction of the cassette 10 is suppressed. Further, since the pressed portion 48 overlaps the convex envelope 146 defined by the supported portions 140, 142, 144 in the vertical direction, the cassette 10 can be mounted in a stable state even with one pressed portion 48.

According to the cassette 10 of the present embodiment, (a) the printing tape roll 26 is supported from below, and a support wall 14a extending in an orthogonal direction orthogonal to the vertical direction is provided, and (b) a pressed portion 48. Is provided at a portion of the support wall 14a facing the presser member 124 of the printing device 102. As a result, even if the pressed portion 48 is pressed by the pressing member 124 of the printing device 102, the pressing force of the pressing member 124 is not directly applied to the upper wall 12a having the front surface 12a1, so that the deformation of the upper wall 12a is suppressed. .. Since the deformation of the upper wall 12a is suppressed, the increase in the tape pull-out resistance due to the contact between the upper wall 12a and the printing 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 protruding portion of the support wall 14a that protrudes upward from the support surface that supports the printing tape roll 26. .. Since the pressed portion 48 is provided on the protruding portion protruding upward from the support wall 14a, the positioning accuracy of the pressed portion 48 with respect to the pressing member 124 of the printing device 102 in the vertical direction is improved. As a result, the cassette 10 can be mounted in a stable and pressed state.

According to the cassette 10 of the present embodiment, the (a) cassette case 19 is partitioned from the first space S1 provided with (a1) the printing tape roll 26 and the first space S1 by (a2) the support wall 14a. It has a second space S2 located below the first space S1. (B) The cassette 10 is extended in the vertical direction between (b1) the specified wall 16a that defines the lower side of the second space S2 and (b2) the lower side of the pressed portion 48 and the specified wall 16a. A first support portion 35A that supports the pressed portion 48 at a position overlapping the hole portion 33 in the vertical direction is provided. The pressed portion 48 is supported by the support wall 14a and also by the defined wall 16a via the first support portion 35A. Since the pressed portion 48 is supported by the support wall 14a and the defined wall 16a, the pressed portion 48 is less likely to be deformed downward in the vertical direction even when pressed by the pressing member 124 of the printing device 102. Therefore, the cassette 10 can be mounted in a stable and pressed state by the pressing member 124 of the printing device 102.

According to the cassette 10 of the present embodiment, the first support portion 35A extends downward from the back surface of the support wall 14a. In this way, since the first support portion 35A is provided integrally with the support wall 14a, the pressed portion 48 receives the pressure as compared with the case where the first support portion 35A is provided as a separate member from the support wall 14a. The pressing force of the pressing member 124 of the printing apparatus 102 can be easily dispersed on the specified wall 16a. Therefore, even if the pressing member 124 of the printing device 102 presses the pressed portion 48, the pressed portion 48 is less likely to be deformed downward in the vertical direction, and the cassette 10 can be mounted in a stable pressed state.
