According to the cassette 10 of the present embodiment, the diameter of the printing tape roll 26 is larger than the size L, which is half the size of the cassette 10 in each of the front-rear direction and the left-right direction. As a result, a high space occupancy in the cassette 10 of the printing tape roll 26 can be obtained, so that the wasted space in the cassette 10 is reduced and the cassette can be miniaturized.

According to the cassette 10 of the present embodiment, the first medium roll (printing tape roll 26) around which the strip-shaped first medium (printing tape 22) is wound and the strip-shaped second medium (bonding tape 60) are wound. The first medium roll includes a second medium roll (bonded tape roll 64) that has been turned, and a third medium roll (ink ribbon roll 72) around which a strip-shaped third medium (ink ribbon 68) is wound. Is provided in the first space S1, and the second medium roll and the third medium roll are separated from the first space S1 in the orthogonal direction (vertical direction) orthogonal to the radial direction of the second medium roll. Provided in S2, at least one of the second medium roll and the third medium roll overlaps the first medium roll in the direction orthogonal to the first medium roll. As a result, the first medium roll, the second medium roll, and the third medium roll are separately provided in the first space and the second space partitioned in the orthogonal direction orthogonal to the radial direction of the second medium roll. Since at least one of the second medium roll and the third medium roll overlaps the first medium roll in the orthogonal direction, the cassette 10 can be miniaturized in the radial direction of the second medium roll.

It should be noted that the above description is merely an embodiment of the present invention, and the present invention can be modified in various ways without departing from the spirit of the present invention.

For example, the cassette 10 of the above embodiment is provided with the roller 80, but the cassette 10 may not be provided with the roller 80. Further, the printing tape roll 26, the bonding tape roll 64, the ink ribbon roll 72, and the take-up spool 76 of the above embodiment are provided horizontally with respect to the front-rear direction and the left-right direction, but these are provided horizontally. It does not have to be. For example, when the bonding tape roll 64 is not provided horizontally with respect to the front-rear direction and the left-right direction, the width direction of the bonding tape 60 is different from the vertical direction of the above embodiment, and the bonding tape roll 64 The direction orthogonal to the radial direction is also a direction different from the vertical direction of the above embodiment. In this case, the first direction which is the width direction or the second direction which is orthogonal to the orthogonal direction orthogonal to the radial direction and the third direction which is orthogonal to the first direction or the orthogonal direction and the second direction are the above-described embodiments. The direction is different from the front-back direction and the left-right direction.

Further, the transfer routes of the printing tape 22, the bonding tape 60, and the ink ribbon 68 are not limited to the routes shown in FIG. 14, and various routes can be appropriately adopted. For example, the ink ribbon 68 may be carried into the ribbon case 21 from the carry-in inlet 132, passed through the left side and the rear side of the bonding tape roll 64, and wound on the take-up spool 76. Even in this case, if at least a part of the ink ribbon 68 carried in from the carry-in inlet 132 overlaps the printing tape roll 26 in the vertical direction, the cassette can be miniaturized in the horizontal direction orthogonal to the vertical direction. Further, the arrangement of the bonding tape roll 64, the ink ribbon roll 72, and the take-up spool 76 is not limited to the position shown in the above embodiment. For example, the bonding tape roll 64 may be arranged on the right side of the take-up spool 76. At least one of the ink ribbon rolls 72 as the third medium roll is housed in the ribbon case 21, one of the printing tape roll 26 and the laminating tape roll 64 is housed in the tape case 20 as the first medium roll, and the other is housed in the second medium roll. It suffices if it is housed in the ribbon case 21 as a medium roll. Even in this case, the one roll housed in the tape case 20 is arranged so as to overlap at least one of the other roll housed in the ribbon case 21 and the ink ribbon roll 72 in the vertical direction. As a result, the cassette 10 can be miniaturized in the radial direction of the bonding tape roll 64 or the printing tape roll 26. In the above embodiment, the bonding tape roll 64, the ink ribbon roll 72, and the take-up spool 76 are all arranged at positions where they overlap the printing tape roll 26 in the vertical direction, but the bonding tape roll 64 and the ink ribbon roll 72 And at least one of the take-up spool 76 may be arranged at a position where it overlaps with the printing tape roll 26 in the vertical direction. Only one of the bonding tape roll 64 and the ink ribbon roll 72 may be arranged at a position where it overlaps with the printing tape roll 26 in the vertical direction.

In the above embodiment, the cassette 10 is configured by stacking four case members, a first case member 12, a second case member 14, a third case member 16, and a fourth case member 18 in the vertical direction. The set 10 is not limited to this configuration. For example, as shown in FIG. 19, the cassette 10 may be configured by stacking three case members, a first case member 12, a fifth case member 501, and a fourth case member 18 in the vertical direction. The fifth case member 501 has through holes 502 that penetrate vertically corresponding to the through holes 52 and 58 of the above embodiment, and partitions the first space S1 and the second space S2. It is preferable that the upper surface side of the fifth case member 501 has the same shape as the upper surface side of the second case member 14, and the lower surface side has the same shape as the lower surface side of the third case member 16. In the case of this modification, the tape case 20 having the first space S1 inside is formed by the first case member 12 and the fifth case member 501, and the fifth case member 501 and the fourth case member 18 form the inside of the tape case 20. A ribbon case 21 having two spaces S2 is configured.

In the above embodiment, the printing tape roll 26 is configured by winding the printing tape 22 around the printing tape spool 24 which is a cylindrical shaft core material, but the printing tape 22 is wound around the printing tape spool 24. Instead, the printing tape roll 26 may be formed by winding around the first support protrusion 30 and the second support protrusion 32. Similarly, the bonding tape 60 is wound without being wound around the bonding spool 62, and the outer circumference of the bonding tape 60 is defined and arranged by the bonding tape roll holding wall 84 and the arcuate wall 92. May be good.

Further, the printing tape roll 26 is not limited to the dimensions shown by the dimensional ratio with respect to the third case member 16 shown in the drawing 16 of the above embodiment, and needs to be arranged at the position shown in FIG. There is no. For example, the diameter of the printing tape roll 26 may be increased so as to be in contact with the inside of the side wall of the tape case 20 and arranged on the left side of the position shown in FIG. In this case, when the printing tape 22 is pulled out from the tape case 20 to the printing place P via the ejection port 130, the printing tape roll 26 overlaps the printing tape 22 ejected from the ejection port 130 in the vertical direction. Become. Further, in this case, the printing tape 22 conveyed in the ribbon case 21 overlaps with the printing tape roll 26 in the vertical direction before being discharged from the discharge port 130. Even if such a configuration is adopted, the cassette can be miniaturized in the orthogonal direction orthogonal to the vertical direction.

In the above embodiment, the bonding tape roll 64 overlaps both the printing tape spool 24 and the printing tape 22 wound around the printing tape spool 24 in the vertical direction, but the bonding tape roll 64 is a printing tape. It may overlap only the printing tape 22 wound around the spool 24 in the vertical direction. Further, the printing tape roll 26 overlapped both the bonding spool 62 and the bonding tape 60 wound around the bonding spool 62 in the vertical direction, but the bonding tape wound around the bonding spool 62. It may overlap only 60 in the vertical direction.
