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.
[0069] 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.
[0070] 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.
[0071] 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.
[0072] 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.
[0073] 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.
[0074] 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.
[0075] 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.
[0076] 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.
[0077] <Composition of the Regulatory Section 50> Here, the configuration of the regulating unit 50 will be explained in detail with reference to Figures 7 to 9. As shown in Figure 7, the restricting portion 50 comprises a pressing portion 51 and a holding portion 52. The pressing portion 51 may be an elastic member that restricts the movement of the printing medium. The pressing portion 51 may also be a thin plate spring.
[0078] The pressing portion 51 comprises a contact portion 51A and a support portion 51B. The contact portion 51A and the support portion 51B may be plate-shaped. The contact portion 51A and the support portion 51B are integrally provided. The contact portion 51A is provided in the first width direction X1 relative to the support portion 51B. The contact portion 51A is supported by the support portion 51B at the rear Y2. The support portion 51B is fixed to the holding portion 52.
[0079] The contact portion 51A includes a contact surface 51C. The contact surface 51C is a surface that can come into contact with the printing medium being transported along the second transport path 19 on the first width direction X1 side. The contact surface 51C is inclined at a predetermined angle. The contact surface 51C is inclined upward Z1 side. The contact surface 51C is inclined rearward Y2 side.
[0080] The contact portion 51A is provided to bend relative to the support portion 51B. When the printing medium comes into contact with the contact portion 51A from the first width direction X1 side, the pressing portion 51 presses the printing medium in the first width direction X1 by its restoring force. Therefore, when the printing medium comes into contact with the contact portion 51A from the first width direction X1 side to the second width direction X2 side, the restoring force of the pressing portion 51 presses the printing medium in the first width direction X1 and upward Z1.
[0081] In particular, the pressing unit 51 is movable along the X-axis in the second transport path 19 between a retracted position shown in Figure 8 and a restricting position shown in Figure 9. The restricting position is in the first width direction X1 relative to the retracted position. The restricting position is a position where the movement of the printing medium is restricted by the pressing unit 51 protruding into the second transport path 19. In this way, the pressing unit 51 is configured to press the printing medium in the second transport path 19 toward the first width direction X1 and upward Z1 by moving to the restricting position.
[0082] As shown in Figures 8 and 9, the second transport path 19 is surrounded by the first inner wall 61 and the second inner wall 62. The first inner wall 61 is provided in the second case 14. The first inner wall 61 constitutes the ceiling surface surrounding the second transport path 19. The first inner wall 61 is a wall portion perpendicular to the upper Z1.
[0083] The second inner wall 62 is provided in the second case 14. The second inner wall 62 may be provided so as to span the first case 13 and the second case 14. The second inner wall 62 constitutes a side surface that surrounds the first width direction X1 in the second transport path 19. The second inner wall 62 is a wall portion parallel to the upper Z1 and the front Y1.
[0084] Thus, the pressing portion 51 is configured to be inclined with respect to the first inner wall 61, the second inner wall 62, and the forward direction Y1. In particular, the pressing portion 51 is configured such that the contact surface 51C is inclined at an angle toward the first inner wall 61, the second inner wall 62, and the rearward direction Y2.
[0085] The holding portion 52 is configured to hold the pressing portion 51. In particular, the holding portion 52 is configured to hold the pressing portion 51 in the first width direction X1. A support portion 51B is fixed to the holding portion 52.
[0086] The holding portion 52 may include a first holding portion 53 and a second holding portion 54. The first holding portion 53 and the second holding portion 54 are constructed separately, but may also be constructed integrally. The first holding portion 53 is located above the second holding portion 54 at Z1. The second holding portion 54 supports the first holding portion 53 from below at Z2. The first holding portion 53 and the second holding portion 54 are connected. The first holding portion 53 and the second holding portion 54 are movable along the X axis.
[0087] The holding portion 52 includes a contact surface 52A. The contact surface 52A is provided in the second width direction X2 of the holding portion 52. The contact surface 52A is provided downward Z2 of the holding portion 52. The contact surface 52A is provided on the second holding portion 54, but may also be provided on the first holding portion 53, or may span both the first holding portion 53 and the second holding portion 54. The contact surface 52A is a surface that inclins downward Z2 toward the second width direction X2.
[0088] The contact surface 52A is located above the insertion hole 23 at Z1. When the ink ribbon cartridge 11 is installed in the cartridge mounting section 107, the contact surface 52A comes into contact with the tip 115A of the protruding portion 115. In other words, the contact surface 52A comes into contact with the protruding portion 115. With the contact surface 52A in contact with the tip 115A of the protruding portion 115, when the tip 115A moves upward Z1 relative to the contact surface 52A, the holding portion 52 moves in the first width direction X1.
[0089] Thus, when the ink ribbon cartridge 11 is mounted in the cartridge mounting section 107, the holding section 52 moves in the first width direction X1, causing the pressing section 51 to move toward the second inner wall 62. As a result, the pressing section 51 restricts the movement of the printing medium in the second width direction X2.
[0090] In other words, when the ink ribbon cartridge 11 is installed in the cartridge mounting section 107, the restricting section 50 restricts the movement of the printing medium in the second width direction X2 by moving toward the second inner wall 62 with the holding section 52 in contact with the protruding section 115.
[0091] The printing medium being transported along the second transport path 19 is pressed in the first width direction X1 and upward Z1 by contacting the contact surface 51C. Therefore, the movement of the printing medium being transported along the second transport path 19 is restricted by the restricting unit 50 in the second width direction X2 and downward Z2.
[0092] Thus, the restricting unit 50 is configured to restrict the movement of the printing medium in the restricting direction in the second transport path 19. The restricting direction includes a component in the second width direction X2 and a component downward Z2. In other words, the restricting direction includes a component along the first width direction X1 and a component along the upward Z1. To put it another way, the restricting direction includes a component along the X axis and a component along the Z axis.
[0093] <Operation and Effects of the First Embodiment> The operation and effects of the first embodiment will now be described. (1-1) Conventionally, printing devices are equipped with components for the stable transport of printing media. This can lead to an increase in the size of the printing device. In this embodiment, the ink ribbon cartridge 11 is equipped with a restricting unit 50 that restricts the movement of the printing media in the restricting direction, including the second width direction X2, in the media transport path 17. With this configuration, the movement of the printing media in the second width direction X2 can be restricted by providing the restricting unit 50 in the ink ribbon cartridge 11 rather than in the printing device 100. This allows for stable transport of the printing media. Therefore, an increase in the size of the printing device 100 can be suppressed.
[0094] (1-2) The restricting unit 50 restricts the movement of the printing medium in the restricting direction, which includes the second width direction X2 and the downward direction Z2. With this configuration, the movement of the printing medium can be restricted in the restricting direction, which includes the downward direction Z2 in addition to the second width direction X2. This makes it possible to transport the printing medium stably.
[0095] (1-3) The media transport path 17 has a first inner wall 61 perpendicular to the Z axis and a second inner wall 62 parallel to the Y axis and the Z axis. The regulating section 50 has a pressing section 51 and a holding section 52 that holds the pressing section 51. The pressing section 51 is configured to be inclined with respect to the first inner wall 61, the second inner wall 62 and the forward Y1 which is the transport direction. With this configuration, the printing medium can be smoothly guided in the media transport path 17 with respect to the first inner wall 61, the second inner wall 62 and the forward Y1 which is the transport direction. This allows the printing medium to be transported stably.
[0096] (1-4) The restricting unit 50 can restrict the movement of the printing medium in the restricting direction by moving toward the second inner wall 62. Therefore, the printing medium can be transported stably.
[0097] (1-5) When the ink ribbon cartridge 11 is installed in the cartridge mounting section 107, the restricting section 50 moves toward the second inner wall 62 with the holding section 52 in contact with the protruding section 115. In this way, the restricting section 50 restricts the movement of the printing medium in the restricting direction. With this configuration, the movement of the printing medium in the restricting direction can be restricted when the ink ribbon cartridge 11 is installed in the cartridge mounting section 107. Therefore, the printing medium can be transported stably while improving operability.
[0098] (1-6) The regulating section 50 is provided at a position along the second transport path 19. With this configuration, the regulating section 50 can be provided in the second transport path 19, which is closer to the printing position P1 compared to the first transport path 18. This allows for stable transport of the printing medium and suppresses a decrease in printing accuracy.
[0099] (1-7) The first transport path 18 extends from the inlet 15 in the first width direction X1, and the second transport path 19 is connected to the first transport path 18 and extends forward Y1. With this configuration, even if the media transport path 17 is connected so that the first transport path 18 and the second transport path 19 intersect, the regulating section 50 can be provided in the second transport path 19, which is downstream of the first transport path 18. This makes it possible to transport the printing medium stably.
[0100] (1-8) The regulating section 50 is located upstream of the head insertion hole 21 along the second transport path 19. This configuration allows the regulating section 50 to be located upstream of the head insertion hole 21. This enables stable transport of the printing medium and suppresses a decrease in printing accuracy.
[0101] (2-1) In conventional ink ribbon cartridges, there were some that allowed the printing medium to be introduced into the cartridge case from the outside, but it was not possible to increase the amount of ink ribbon that could be housed in the cartridge case. Therefore, in this embodiment, when the ink ribbon cartridge 11 is installed in the printing device 100, the rotation axis of the winding roll 32 on which the ink ribbon 30 is wound is parallel to the rotation axis of the winding shaft 114, and different from the rotation axis of the winding shaft 114. The gear train 40 is configured to transmit the power of the winding shaft 114 to the winding roll 32. With this configuration, by transmitting the power of the winding shaft 114 to the winding roll 32 via the gear train 40, the rotation axis of the winding roll 32 and the rotation axis of the winding shaft 114 can be made different. This makes it possible to adjust the arrangement of the area for housing the winding 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.
[0102] (2-2) 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.
[0103] (2-3) The gear train 40, in a top view, has a first gear 41 coaxial with the winding shaft 114, a third gear 43 with 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 a predetermined distance into consideration. Therefore, the amount of ink ribbon 30 that can be accommodated in the cartridge case 12 can be increased.
[0104] (2-4) 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.
[0105] (2-5) 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.
[0106] (2-6) 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.
[0107] (2-7) 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 an ink ribbon housing area 28 that prevents the feed roll 31 from interfering with 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.
[0108] (2-8) 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 housed in the cartridge case 12 can be increased while suppressing an increase in the size of the first case 13.
[0109] [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.
[0110] 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.
[0111] 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.
[0112] 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.
[0113] 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.
[0114] 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.
[0115] 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.
[0116] 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.
[0117] The restricting portion 50 may move in the first width direction X1 by contact with a part other than the tip portion 115A of the protruding portion 115 when the ink ribbon cartridge 11 is mounted in the cartridge mounting portion 107. The restricting portion 50 may move in the first width direction X1 by contact with a part of the printing device 100 other than the protruding portion 115 when the ink ribbon cartridge 11 is mounted in the cartridge mounting portion 107. The other part may be, for example, the feed shaft.
[0118] The regulating unit 50 may move in the first width direction X1 in response to an operation other than the installation operation when the ink ribbon cartridge 11 is installed in the cartridge installation unit 107. The regulating unit 50 may also move in the first width direction X1 in response to an operation of an operation unit provided on the ink ribbon cartridge 11. In such a case, the holding unit 52 does not need to have a contact surface 52A as long as it can move in the first width direction X1 in response to the operation of the operation unit.
[0119] The restricting unit 50 may be positioned to restrict the movement of the printing medium in the restricting direction. Thus, the restricting unit 50 does not need to move along the X-axis as long as it can restrict the movement of the printing medium in the restricting direction. The holding unit 52 does not need to have a contact surface 52A.
[0120] The contact surface 51C does not need to be inclined with respect to any of the X, Y, and Z axes. In other words, the pressing part 51 does not need to be inclined with respect to any of the X, Y, and Z axes. Thus, as long as the restricting part 50 can restrict the movement of the printing medium in the restricting direction, the pressing part 51 does not need to be inclined with respect to any of the X, Y, and Z axes.
[0121] The restricting direction includes downward Z2, but is not limited to this; for example, it may also include upward Z1. Thus, the restricting direction may include the Z-axis component. In other words, the restricting direction only needs to include a component along upward Z1. The restricting direction does not need to include the Z-axis component.
[0122] The restricting section 50 may be provided in the first width direction X1 relative to the media transport path 17. If the restricting section 50 is provided in the first width direction X1 relative to the media transport path 17, the restricting direction may include the first width direction X1. Thus, the restricting direction only needs to include the X-axis component. In other words, the restricting direction only needs to include the component along the first width direction X1.
[0123] The first inner wall 61 may be substantially perpendicular to the Z-axis. The second inner wall 62 may be substantially parallel to the Y-axis and the Z-axis. In other words, the first inner wall in the claim includes a first inner wall that is substantially perpendicular to the Z-axis. The second inner wall in the claim includes a second inner wall that is substantially parallel to the Y-axis and the Z-axis.
[0124] The restricting section 50 may be located downstream of the printing position P1 in the second transport path 19. The restricting section 50 may be located along the first transport path 18. The restricting section 50 may be located along the discharge path 20. The restricting section 50 does not have to be located upstream of the printing position P1 in the second transport path 19. The restricting section 50 does not have to be located upstream of the head insertion hole 21 in the second transport path 19. The ink ribbon cartridge 11 may have a plurality of restricting sections 50.
[0125] The ink ribbon cartridge 11 does not necessarily have to include a gear train 40. In this case, the rotation axis of the winding shaft 114 of the printing device 100 and the rotation axis of the winding roll 32 may be the same in the ink ribbon cartridge 11.
[0126] 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.
[0127] 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.
[0128] 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.
[0129] 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.
[0130] 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.

[0131] [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.
[0132] [1-1] An ink ribbon cartridge is an ink ribbon cartridge that is installed in a printing device that prints on a tubular printing medium that can be introduced from outside the ink ribbon cartridge, and comprises: an ink ribbon storage area in the cartridge case in which an ink ribbon can be housed; a head insertion hole in the cartridge case through which the head of the printing device can be inserted at the printing position in the cartridge case; an inlet for introducing a tubular printing medium into the cartridge case; a media transport path that connects at least the inlet and the printing position and through which the tubular printing medium introduced from the inlet is transported to the printing position; and a restricting section that restricts the movement of the tubular printing medium in the media transport path, including a component along a first direction that intersects the transport direction of the tubular printing medium and the insertion direction through which the head is inserted into the head insertion hole.
[0133] With this configuration, by providing a restricting section on the ink ribbon cartridge rather than the printing device, the movement of the tubular printing medium in the restricting direction, including a component along the first direction intersecting the transport direction and the insertion direction, can be restricted. This allows for stable transport of the tubular printing medium. Therefore, it is possible to suppress the need for larger printing devices.
[0134] [1-2] The above-mentioned ink ribbon cartridge may include a component along the first direction and a component along the insertion direction. This configuration allows for the restriction of movement of the tubular printing medium in the restricting direction, including components along the insertion direction in addition to components along the first direction. This enables stable transport of the tubular printing medium.
[0135] [1-3] The ink ribbon cartridge described above, wherein the medium transport path has a first inner wall perpendicular to the insertion direction and a second inner wall parallel to the transport direction and the insertion direction, and the regulating portion has a pressing portion and a holding portion that holds the pressing portion, and the pressing portion may be configured to be inclined with respect to the first inner wall, the second inner wall and the transport direction.
[0136] In this configuration, the pressing section is configured to be inclined with respect to the first inner wall, the second inner wall, and the transport direction. Therefore, the tubular printing medium can be smoothly guided along the medium transport path with respect to the first inner wall, the second inner wall, and the transport direction. This enables stable transport of the tubular printing medium.
[0137] [1-4] In the above-mentioned ink ribbon cartridge, the restricting portion may restrict the movement of the tubular printing medium in the direction opposite to the first direction by moving toward the second inner wall.
[0138] With this configuration, by moving the regulating part toward the second inner wall, the movement of the tubular printing medium in the opposite direction to the first direction can be restricted. Therefore, the tubular printing medium can be transported stably.
[0139] [1-5] The ink ribbon cartridge has an insertion hole through which a protruding part of the printing device that protrudes in the insertion direction when the ink ribbon cartridge is mounted on the cartridge mounting part of the printing device can be inserted, and when the ink ribbon cartridge is mounted on the cartridge mounting part of the printing device, the regulating part may move toward the second inner wall with the holding part in contact with the protruding part.
[0140] With this configuration, when the ink ribbon cartridge is installed in the cartridge mounting section, the protruding portion inserted into the insertion hole and the holding portion that holds the pressing portion come into contact, thereby moving the restricting portion toward the second inner wall. This restricts the movement of the tubular printing medium in the opposite direction to the first direction when the ink ribbon cartridge is installed in the cartridge mounting section. Therefore, the tubular printing medium can be transported stably while improving operability.
[0141] [1-6] The ink ribbon cartridge described above, wherein the holding portion has a contact surface in the direction opposite to the insertion direction, and the contact surface may be a surface that contacts the protruding portion and is inclined in the insertion direction toward the direction opposite to the first direction. This can produce the same effect as in [1-4].
[0142] [1-7] The ink ribbon cartridge described above, wherein the media transport path comprises a first transport path and a second transport path including the printing position, and the regulating section may be provided at a position along the second transport path.
[0143] This configuration allows for the placement of a regulating section in the second transport path, which is closer to the printing position compared to the first transport path. This enables stable transport of tubular printing media and suppresses a decrease in printing accuracy.
[0144] [1-8] The ink ribbon cartridge described above, wherein the first transport path extends from the inlet in the first direction, and the second transport path is connected to the first transport path and may extend in a second direction intersecting the first direction and the insertion direction.
[0145] With this configuration, even in a media transport path where the first and second transport paths intersect, a regulating section can be provided in the second transport path, which is downstream of the first transport path. This allows for stable transport of tubular printing media.
[0146] [1-9] In the above-mentioned ink ribbon cartridge, the restricting portion may be provided upstream of the head insertion hole in the second transport path. This configuration allows a regulating section to be placed upstream of the print head insertion hole. This enables stable transport of tubular printing media and suppresses a decrease in printing accuracy.
[0147] [2-1] 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.
[0148] 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.
[0149] [2-2] The above-mentioned ink ribbon cartridge, 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.
[0150] 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.
[0151] [2-3] 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 power from 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.
[0152] 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.
[0153] [2-4] In the above ink ribbon cartridge, 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.
[0154] [2-5] In the above-mentioned ink ribbon cartridge, 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.
[0155] 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.
[0156] [2-6] 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.
[0157] 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.
[0158] [2-7] 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.
[0159] 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.
[0160] [2-8] 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.
[0161] 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. [Explanation of Symbols]
