The media transport path 17 is a path that connects the printing position P1 and the discharge port 16. The media transport path 17 is a path that transports the printing medium so that the printing medium printed at the printing position P1 is discharged from the discharge port 16.

[0041] The media transport path 17 comprises a first transport path 18, a second transport path 19, and a discharge path 20. The first transport path 18 is connected to the inlet 15. The first transport path 18 extends along the X-axis. The first transport path 18 extends from the inlet 15 in the first width direction X1. Thus, in the first transport path 18, the transport direction in which the printing media is transported is the first width direction X1.

[0042] The second transport path 19 is connected to the first transport path 18. The second transport path 19 includes a path extending along the Y-axis. The second transport path 19 includes a path extending forward Y1 from the first transport path 18. The printing position P1 is a position along the second transport path 19. In other words, the second transport path 19 is a path that includes the printing position P1. Thus, in the second transport path 19, the transport direction in which the printing medium is transported is forward Y1.

[0043] In this embodiment, the second transport path 19 includes a path that extends inclined forward Y1 and in the first width direction X1, but it does not have to include a path that extends inclined forward Y1 and in the first width direction X1.

If the ink ribbon cartridge 11 is installed in a different model than the printing device 100, a feed shaft of a different model may be inserted through the second feed shaft insertion hole 27.

[0058] As shown in Figure 5, the cartridge case 12 includes an ink ribbon storage area 28. The ink ribbon storage area 28 is located on the second case 14 side in the Z-axis direction. Although the ink ribbon storage area 28 is located on the second case 14 in the Z-axis direction, it may also be located so as to span both the second case 14 and the first case 13.

[0059] The ink ribbon storage area 28 is an area within the cartridge case 12 in which the ink ribbon 30 can be stored. The ink ribbon storage area 28 is an area for storing the feed roll 31. The ink ribbon storage area 28 is an area for storing the rewind roll 32.

[0062] The ink ribbon cartridge 11 comprises a gear train housing area 29 and a gear train 40. The gear train housing area 29 is provided in the cartridge case 12. The gear train housing area 29 is the area that houses the gear train 40. In other words, the gear train 40 is housed in the cartridge case 12.

[0063] The gear train storage area 29 is provided on the first case 13 side in the Z-axis. The gear train storage area 29 is provided on the first case 13 in the Z-axis, but it may also be provided so as to span the first case 13 and the second case 14. The gear train storage area 29 is provided so as to overlap with the ink ribbon storage area 28 in a top view.

[0064] As shown in Figures 5 and 6, when the ink ribbon cartridge 11 is mounted in the cartridge mounting section 107, the gear train 40 is configured to transmit power from the winding shaft 114, which is inserted through the winding shaft insertion hole 25, to the winding roll 32.

[0065] The gear train 40 may be configured to rotate the winding roll 32 in the first circumferential direction R1 when the winding shaft 114 rotates in the first circumferential direction R1. The gear train 40 may be configured to have a 1:1 ratio between the rotational speed of the winding shaft 114 and the rotational speed of the winding roll 32.

[0066] The gear train 40 may include a first gear 41, a second gear 42, and a third gear 43. The rotation axis of the first gear 41 is the first rotation axis Z11. The first rotation axis Z11 is along the Z axis. When the ink ribbon cartridge 11 is mounted in the cartridge mounting section 107, the first gear 41 is coaxial with the winding shaft 114. In other words, when the ink ribbon cartridge 11 is mounted in the cartridge mounting section 107, the first rotation axis Z11 is the same as the rotation axis of the winding shaft 114. Thus, the first rotation axis Z11 is both the rotation axis of the winding shaft 114 and the rotation axis of the first gear 41. Power from the winding shaft 114 is transmitted to the first gear 41.

[0067] The rotation axis of the second gear 42 is the second rotation axis Z12. The second rotation axis Z12 lies along the Z axis. The second rotation axis Z12 is positioned parallel to the first rotation axis Z11, and its position on the XY plane, i.e., on the bottom surface of the first case 13 intersecting the Z axis, is different from that of the first rotation axis Z11.

[0068] The second gear 42 is configured to mesh with the first gear 41. The second gear 42 is configured to mesh with the third gear 43. In this way, the second gear 42 is configured to transmit the power of the first gear 41 to the third gear 43.

[0069] The rotation axis of the third gear 43 is the third rotation axis Z13. The third rotation axis Z13 lies along the Z axis. The third gear 43 is positioned parallel to the first rotation axis Z11 and coaxial with the winding roll 32. In other words, the third rotation axis Z13 is the same as the rotation axis of the winding roll 32. The position of the third rotation axis Z13 on the XY plane, that is, on the bottom surface of the first case 13 intersecting the Z axis, is different from that of the first rotation axis Z11. Thus, the third rotation axis Z13 is both the rotation axis of the third gear 43 and the rotation axis of the winding roll 32. Power from the second gear 42 is transmitted to the third gear 43. In other words, the third gear 43 transmits power from the winding shaft 114 to the winding roll 32.

[0070] Thus, when the ink ribbon cartridge 11 is mounted in the cartridge mounting section 107, the rotation axis of the winding roll 32 is positioned parallel to the rotation axis of the winding shaft 114, and is different from the rotation axis of the winding shaft 114. The downward Z2 corresponds to an example of the first axial direction, and the upward Z1 corresponds to an example of the opposite direction of the first axial direction.

[0071] In particular, the third rotation axis Z13 is located in the second width direction X2 relative to the first rotation axis Z11. The third rotation axis Z13 is located further away from the second transport path 19 relative to the first rotation axis Z11. The third rotation axis Z13 is located at a predetermined distance from the fourth rotation axis Z14. The fourth rotation axis Z14 is the rotation axis of the feed roll 31.

[0072] The predetermined distance is a distance corresponding to the amount of ink ribbon 30 that can be stored. The predetermined distance may be longer than the sum of the radius of the dispensing roll 31 and the radius of the rewinding roll 32. The predetermined distance may be longer than or equal to the radius of the dispensing roll 31 when it is not in use and the ink ribbon 30 is not being dispensed. The radius of the dispensing roll 31 when it is not in use and the ink ribbon 30 is not being dispensed is the maximum radius of the dispensing roll 31. The predetermined distance may be longer than or equal to the radius of the rewinding roll 32 that is expected when the entire ink ribbon 30 has been rewinded. The radius of the rewinding roll 32 that is expected when the entire ink ribbon 30 has been rewinded is the maximum radius of the rewinding roll 32.

[0073] The feed roll 31 is positioned in the area of ​​the ink ribbon storage area 28 that is enclosed by the first transport path 18, the second transport path 19, and the gear train storage area 29, when viewed from above. The feed roll 31 is positioned in the area between the insertion hole 23 and the gear train storage area 29, when viewed from above. The insertion hole 23 is provided in the area enclosed by the first transport path 18, the second transport path 19, and the ink ribbon storage area 28.

[0074] As shown in Figure 4, the first case 13 includes a side wall 13A in the second width direction X2. The second case 14 includes a side wall 14A in the second width direction X2. In this embodiment, in a top view, the side wall 14A is located further in the second width direction X2 than the side wall 13A.

[0075] Thus, in a top view, the second case 14 is configured to protrude from the side wall 13A of the first case 13. In a top view, the ink ribbon housing area 28 may include an area that protrudes outward from the side wall 13A of the first case 13 in the second width direction X2.

[0076] <Operation and Effects of the First Embodiment> The operation and effects of the first embodiment will now be described. (1) When the ink ribbon cartridge 11 is installed in the printing device 100, the rotation axis of the take-up roll 32 on which the ink ribbon 30 is wound is parallel to the rotation axis of the take-up shaft 114, and different from the rotation axis of the take-up shaft 114. The gear train 40 is configured to transmit the power of the take-up shaft 114 to the take-up roll 32. With this configuration, by transmitting the power of the take-up shaft 114 to the take-up roll 32 via the gear train 40, the rotation axis of the take-up roll 32 and the rotation axis of the take-up shaft 114 can be made different. This makes it possible to adjust the arrangement of the area for housing the take-up roll 32 inside the cartridge case 12. Therefore, the amount of ink ribbon 30 that can be housed in the cartridge case 12 can be increased.

[0077] (2) The cartridge case 12 comprises a first case 13 and a second case 14 located above the first case 13 in Z1. The first case 13 has a gear train housing area 29 for housing the gear train 40. The second case 14 has an inlet 15 for introducing printing media into the cartridge case 12, a media transport path 17 for transporting the printing media, and an ink ribbon housing area 28 for housing the feed roll 31 and the take-up roll 32. With this configuration, the gear train housing area 29 for housing the gear train 40 is provided in the first case 13, while the inlet 15, the media transport path 17, and the ink ribbon housing area 28 are provided in the second case 14. This allows the gear train housing area 29 to be provided in the first case 13 without interfering with the inlet 15, the media transport path 17, and the ink ribbon housing area 28 in the second case 14. Therefore, the amount of ink ribbon 30 that can be housed in the cartridge case 12 can be increased.

[0078] (3) The gear train 40, in a top view, has a first gear 41 that is coaxial with the winding shaft 114, a third gear 43 that has the same rotation axis as the winding roll 32, and a second gear 42 that transmits the power of the first gear 41 to the third gear 43. The rotation axis of the third gear 43 is a predetermined distance away from the rotation axis of the feed roll 31. With this configuration, the power of the winding shaft 114 can be transmitted to the winding roll 32 by using the first gear 41, the second gear 42, and the third gear 43. In addition, the rotation axis of the winding roll 32, which is coaxial with the third gear 43, and the rotation axis of the feed roll 31 can be separated by a predetermined distance. This makes it possible to accommodate an amount of ink ribbon 30 that takes into account a predetermined distance. Therefore, the amount of ink ribbon 30 that can be accommodated in the cartridge case 12 can be increased.

[0079] (4) The gear train 40 rotates the take-up roll 32 in the first circumferential direction R1 when the take-up shaft 114 rotates in the first circumferential direction R1. With this configuration, the rotation direction of the take-up shaft 114 and the rotation direction of the take-up roll 32 can be made to rotate in the same first circumferential direction R1. This makes it possible to suppress a decrease in print quality. In addition, it does not require changing the configuration of the printing apparatus 100.

[0080] (5) The gear train 40 is configured such that the ratio of the rotational speed of the winding shaft 114 to the rotational speed of the winding roll 32 is 1:1. With this configuration, the rotational speed of the winding shaft 114 and the rotational speed of the winding roll 32 can be made the same ratio. This makes it possible to suppress a decrease in print quality. In addition, it does not require changing the configuration of the printing apparatus 100.

[0081] (6) The media transport path 17 includes a first transport path 18 extending from the inlet 15 along the first width direction X1, and a second transport path 19 connected to the first transport path 18 and extending along the forward direction Y1. In a top view, the feed roll 31 is positioned in the area of ​​the ink ribbon storage area 28 that is surrounded by the first transport path 18, the second transport path 19, and the gear train storage area 29. With this configuration, the ink ribbon storage area 28 can be provided so that the feed roll 31 does not interfere with the first transport path 18, the second transport path 19, and the gear train storage area 29. Therefore, the amount of ink ribbon 30 that can be stored in the cartridge case 12 can be increased.

[0082] (7) The cartridge case 12 is provided with an insertion hole 23 through which the protruding portion 115 is inserted when the ink ribbon cartridge 11 is installed in the cartridge mounting section 107. When the ink ribbon cartridge 11 is installed in the cartridge mounting section 107, in a top view, the feed roll 31 is positioned in the area between the insertion hole 23 and the gear train housing area 29. With this configuration, in a top view, the feed roll 31 is positioned in the area between the insertion hole 23 through which the protruding portion 115 can be inserted and the gear train housing area 29. This makes it possible to provide the ink ribbon housing area 28 so as not to interfere with the feed roll 31 between the protruding portion 115 inserted into the insertion hole 23 and the gear train housing area 29. Therefore, the amount of ink ribbon 30 that can be housed in the cartridge case 12 can be increased. In addition, the ink ribbon cartridge 11 and a tape cartridge (not shown) can be selectively installed in the printing device 100.

[0083] (8) The second case 14 is configured to protrude outward from the side wall 13A of the first case 13 when viewed from above. The ink ribbon storage area 28 includes an area that protrudes outward from the side wall 13A of the first case 13 when viewed from above. With this configuration, the second case 14, in which the ink ribbon storage area 28 is provided, can be provided so as to protrude outward from the side wall 13A of the first case 13, in which the gear train storage area 29 is provided. Therefore, the amount of ink ribbon 30 that can be stored in the cartridge case 12 can be increased while suppressing an increase in the size of the first case 13.

[0084] [Second Embodiment] Next, a second embodiment will be described. In the following description, redundant explanations of the same configuration as in the previously described embodiment will be omitted or simplified, and configurations that differ from those in the previously described embodiment will be described.

[0085] As shown in Figure 7, in the second embodiment, the feed core 31A and the winding core 32A may be positioned at any location. The feed core 31A may be located further in the second width direction X2 than the winding core 32A.

[0086] The media transport path 17 may include a first transport path 18 that is inclined diagonally with respect to the first width direction X1 and the front direction Y1, rather than a first transport path 18 and a second transport path 19. The first transport path 18 may be connected to the discharge path 20. The first transport path 18 may be provided in front of the insertion hole 23 Y1 rather than behind the insertion hole 23 Y2.

[0087] In this case, when the ink ribbon cartridge 11 is mounted in the cartridge mounting section 107, in a top view, the feed roll 31 is positioned in the area opposite the platen roller 22 with respect to the virtual straight line VL. The virtual straight line VL intersects the media transport path 17. The virtual straight line VL is a straight line connecting the center of the insertion hole 23 and the center of the rotation axis of the winding shaft 114.

[0088] <Operation and Effects of the Second Embodiment> The operation and effects of the second embodiment will now be described. (9) When the ink ribbon cartridge 11 is installed in the cartridge mounting section 107, in a top view, the feed roll 31 is positioned in the area opposite the platen roller 22 with respect to the virtual straight line VL. With this configuration, the ink ribbon storage area 28 can be provided so that the feed roll 31 does not interfere with the protruding portion 115 inserted into the insertion hole 23 and the platen roller 22. Therefore, the external dimensions of the cartridge case 12 can be made smaller while increasing the amount of ink ribbon 30 that can be stored in the cartridge case 12. In addition, the ink ribbon cartridge 11 and the tape cartridge can be selectively installed in the printing device 100.

[0089] [Third Embodiment] Next, a third embodiment will be described. As shown in Figure 8, the third embodiment may be configured such that the feed roll 31 does not protrude significantly from the side wall 13A of the first case 13, compared to the second embodiment. In a top view, the feed roll 31 is positioned in the region opposite to the platen roller 22 with respect to the virtual straight line VL, which is common to the second embodiment. Therefore, the external dimensions of the cartridge case 12 can be reduced while increasing the amount of ink ribbon 30 that can be housed in the cartridge case 12.

[0090] [Example of changes] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0091] The second case 14 may be configured so as not to protrude from the side wall 13A of the first case 13 when viewed from above. The ink ribbon storage area 28 may be an area that does not protrude from the side wall 13A of the first case 13 when viewed from above.

[0092] The ink ribbon storage area 28 may span across the first case 13 and the second case 14, provided that the winding roll 32 is positioned on the Z-axis so as not to interfere with the gear train 40. The gear train storage area 29 may span across the first case 13 and the second case 14, provided that the gear train 40 is positioned on the Z-axis so as not to interfere with the winding roll 32.

[0093] The ink ribbon storage area 28 may be located in a position where the feed roll 31 is not surrounded by the media transport path 17, as long as it does not interfere with the media transport path 17. The gear train 40 does not have to have a 1:1 ratio between the rotational speed of the winding shaft 114 and the rotational speed of the winding roll 32. In other words, the gear train 40 may be configured such that the rotational speed of the winding roll 32 is slower than the rotational speed of the winding shaft 114. The gear train 40 may also be configured such that the rotational speed of the winding roll 32 is faster than the rotational speed of the winding shaft 114.

[0094] The gear train 40 may rotate the winding shaft 114 and the winding roll 32 in the same direction opposite to the first circumferential direction R1. The rotation direction of the winding shaft 114 and the rotation direction of the winding roll 32 are not necessarily the same in the gear train 40.

[0095] The gear train 40 may comprise two or more gears. The gear train 40 may have an odd number of gears so that the direction of rotation of the winding shaft 114 and the direction of rotation of the winding roll 32 are the same. The gears included in the gear train 40 may include gears whose axis of rotation is not parallel.

[0096] Before the ink ribbon cartridge 11 is installed in the printing device 100, the printing medium may be introduced into the ink ribbon cartridge 11 from the outside through the inlet 15 and drawn into the first transport path 18 and the second transport path 19. In this case, the ink ribbon cartridge 11 is installed in the printing device 100 with the printing medium drawn into the first transport path 18 and the second transport path 19.

[0097] After the ink ribbon cartridge 11 is installed in the printing device 100, the printing medium may be introduced into the ink ribbon cartridge 11 from the outside through the inlet 15 and drawn into the first transport path 18 and the second transport path 19. In this case, the printing medium may be drawn into the second transport path 19 against the restriction in the restricting direction by the restricting unit 50.

[0098] The media transport route 17 may include other routes besides the first transport route 18, the second transport route 19, and the discharge route 20. The media transport route 17 does not have to be a route that intersects the first transport route 18 and the second transport route 19.

[0099] The cartridge case 12 does not need to have an insertion hole 23. The cartridge case 12 does not need to have a first feed shaft insertion hole 26. The cartridge case 12 does not need to have a second feed shaft insertion hole 27.

[0100] The printing device 100 may include the platen roller 22 itself. The ink ribbon cartridge 11 may not include the platen roller 22, but may have a platen roller insertion hole. The platen roller insertion hole is a hole through which the platen roller 22 can be inserted. When the ink ribbon cartridge 11 is installed in the cartridge mounting section 107, the platen roller 22 is inserted through the platen roller insertion hole.

[0101] The ink ribbon cartridge 11 may print on a different printing medium, such as tape, rather than a tubular printing medium. The ink ribbon cartridge 11 may contain a printing medium separately from the ink ribbon 30.

[0102] As used herein, the expression "at least one of" means one or more of the desired options. For example, as used herein, if there are two options, the expression "at least one of" means either one option or both of the two options. As another example, as used herein, if there are three or more options, the expression "at least one of" means either one option or any combination of two or more options.

[0103] [Note] The following describes the technical concepts and their effects as understood from the embodiments and modifications described above. These technical concepts and their effects can be combined with each other to the extent that they do not contradict each other.

[0104] [1] An ink ribbon cartridge is an ink ribbon cartridge mounted on a printing device having a winding shaft for winding an ink ribbon, comprising a cartridge case for housing the ink ribbon and a gear train housed in the cartridge case, wherein, when mounted on the printing device, the rotation axis of the winding roll on which the ink ribbon is wound is different from the rotation axis of the winding shaft, and the gear train is configured to transmit the power of the winding shaft to the winding roll.

[0105] This configuration allows the rotation axis of the winding roll and the rotation axis of the winding shaft to be diverged by transmitting power from the winding shaft to the winding roll via a gear train. This allows for adjustment of the arrangement of the area housing the winding roll inside the cartridge case. Consequently, the amount of ink ribbon that can be housed in the cartridge case can be increased.

[0106] [2] The ink ribbon cartridge described above, wherein the cartridge case comprises a first case and a second case located in the opposite direction to the first axial direction along the rotation axis of the winding roll compared to the first case, the first case having a gear train housing area for housing the gear train, and the second case having an inlet for introducing a printing medium into the cartridge case, a medium transport path for transporting the printing medium, and an ink ribbon housing area for housing a feed roll from which the ink ribbon is unfurled and the winding roll.

[0107] With this configuration, the gear train housing area for accommodating the gear train is provided in the first case, while the inlet, media transport path, and ink ribbon housing area for accommodating the feed roll and take-up roll are provided in the second case. This allows the gear train housing area to be provided in the first case without interfering with the inlet, media transport path, and ink ribbon housing area in the second case. Therefore, the amount of ink ribbon that can be housed in the cartridge case can be increased.

[0108] [3] The ink ribbon cartridge described above, wherein the gear train comprises a first gear coaxial with the winding shaft when viewed from the first axial direction, a third gear having the same rotation axis as the winding roll when viewed from the first axial direction, and a second gear that transmits the power of the first gear to the third gear, and the rotation axis of the third gear may be a predetermined distance away from the rotation axis of the feed roll.

[0109] With this configuration, the power of the winding shaft can be transmitted to the winding roll by using the first, second, and third gears. In addition, the rotation axis of the winding roll, which is coaxial with the third gear, and the rotation axis of the unwinding roll can be separated by a predetermined distance. This allows for the storage of an ink ribbon with a capacity that takes this predetermined distance into consideration. Therefore, the capacity of the ink ribbon stored in the cartridge case can be increased.

[0110] [4] The ink ribbon cartridge described above, wherein the gear train may rotate the winding roll in the first circumferential direction when the winding shaft rotates in the first circumferential direction. This configuration allows the winding shaft and the winding roll to rotate in the same first rotational direction. This helps to suppress a decrease in print quality. In addition, it does not require any changes to the configuration of the printing apparatus.

[0111] [5] The ink ribbon cartridge described above, wherein the gear train may be configured such that the ratio of the rotational speed of the winding shaft to the rotational speed of the winding roll is 1:1.

[0112] This configuration allows the rotational speed of the winding shaft and the winding roll to be at the same ratio. This helps to suppress a decrease in print quality. In addition, it does not require any changes to the configuration of the printing apparatus.

[0113] [6] The ink ribbon cartridge described above, wherein the medium transport path comprises a first transport path extending from the inlet along a first direction intersecting the first axial direction, and a second transport path connected to the first transport path and extending along a second direction intersecting the first axial direction and the first direction, and the feed roll may be arranged in the area of ​​the ink ribbon housing area that is surrounded by the first transport path, the second transport path, and the gear train housing area, as viewed from the first axial direction.

[0114] With this configuration, the ink ribbon storage area can be provided in such a way that the feed rolls do not interfere with the first transport path, the second transport path, and the gear train storage area. Therefore, the amount of ink ribbon that can be stored in the cartridge case can be increased.

[0115] [7] In the above-mentioned ink ribbon cartridge, the ink ribbon cartridge and a tape cartridge housing a printing tape roll can be selectively mounted in the cartridge mounting section of the printing device, and when the tape cartridge is mounted in the cartridge mounting section, a projection provided in the cartridge mounting section is inserted through the rotation center of the printing tape roll, the cartridge case is provided with an insertion hole through which the projection is inserted when the ink ribbon cartridge is mounted in the cartridge mounting section, and when the ink ribbon cartridge is mounted in the cartridge mounting section, the feed roll may be positioned in the region between the insertion hole and the gear train housing area when viewed from the first axial direction.

[0116] In this configuration, when viewed from the first axial direction, the feed roll is positioned in the area between the insertion hole through which the protrusion can be inserted and the gear train housing area. This allows the ink ribbon housing area to be provided without interference between the feed roll and the protrusion inserted into the insertion hole and the gear train housing area. Therefore, the amount of ink ribbon that can be housed in the cartridge case can be increased. In addition, ink ribbon cartridges and tape cartridges can be selectively installed in the printing device.

[0117] [8] The ink ribbon cartridge described above, wherein the second case is configured to protrude outward from the side wall of the first case when viewed from the first axial direction, and the ink ribbon housing area may include an area that protrudes outward from the side wall of the first case when viewed from the first axial direction.

[0118] With this configuration, the second case, which houses the ink ribbon, can be positioned so as to protrude outward from the side wall of the first case, which houses the gear train. Therefore, it is possible to increase the amount of ink ribbon that can be housed in the cartridge case while suppressing an increase in the size of the first case.

[0119] [9] The ink ribbon cartridge further comprises a platen roller, and the ink ribbon cartridge and a tape cartridge housing a printing tape roll can be selectively mounted in the cartridge mounting section of the printing device, and when the tape cartridge is mounted in the cartridge mounting section, a projection provided in the cartridge mounting section is inserted through the rotation center of the printing tape roll, the cartridge case is provided with a through hole through which the projection is inserted when the ink ribbon cartridge is mounted in the cartridge mounting section, and when the ink ribbon cartridge is mounted in the cartridge mounting section, the feed roll may be positioned in a region opposite to the platen roller with respect to a virtual straight line that intersects the media transport path and connects the center of the through hole to the center of the rotation axis of the winding shaft, when viewed from the first axial direction.

[0120] In this configuration, when viewed from the first axial direction, the feed roll intersects the media transport path and is positioned in the region opposite the platen roller with respect to a virtual straight line connecting the center of the insertion hole and the center of the rotation axis of the winding shaft. This allows for the provision of an ink ribbon storage area without interference between the feed roll and the protruding portion inserted into the insertion hole and the platen roller. Therefore, the external dimensions of the cartridge case can be reduced while increasing the amount of ink ribbon that can be stored in the cartridge case. In addition, ink ribbon cartridges and tape cartridges can be selectively installed in the printing device. [Explanation of Symbols]
