[Unrolling side tube and winding side tube]
Based on FIGS. 9 and 10, the configuration around the take-up-side tubular portion 277 and the take-up-side tubular portion 279 will be further described. Here, a guide imaginary line 325 that connects the take-up side tube portion 279 and the second ribbon guide 283 when viewed from the front side in the mounting direction is assumed. More specifically, the guide imaginary line 325 is a portion where the second ink ribbon 213 contacts the second ink ribbon 213 in the take-up side tube portion 279 and a second ink ribbon in the second ribbon guide 283 when viewed from the front side of the installation direction. The imaginary line connected by the 213 contact portions. The first ribbon guide 281 is located closer to the inside of the ribbon cassette 200 than the guide imaginary line 325 when viewed from the front side of the installation direction. Therefore, the second ink ribbon 213 is transported between the take-up side cylinder portion 279 and the second ribbon guide 283 closer to the inside of the ribbon cassette 200 than the guide virtual line 325.

In addition, it is assumed that an inter-cylinder imaginary line 327 connecting the take-up side tube portion 277 and the take-up side tube portion 279 when viewed from the front side in the mounting direction. More specifically, the inter-cylinder imaginary line 327 is an imaginary line connecting the center of the take-up side tube portion 277 and the center of the take-up side tube portion 279 when viewed from the front side of the installation direction. When viewed from the front side in the mounting direction, the second ink ribbon 213 conveyed from the second winding core 205 to the second ribbon exposed portion 221 passes through one side of the virtual line 327 between the cylinders. When viewed from the front side in the mounting direction, the second ink ribbon 213 conveyed from the second ribbon exposed portion 221 to the second winding core 207 passes the other side of the inter-cylinder imaginary line 327. When the first ribbon guide 281 is viewed from the front side in the mounting direction, it is disposed on the downstream side of the second ink ribbon 213 in the conveying direction of the second ink ribbon 213 so as to oppose the blocking portion 329 described below.

Between the take-up-side tubular portion 277 and the take-up-side tubular portion 279, a blocking portion 329 is provided to close the space between the take-up-side tubular portion 277 and the take-up-side tubular portion 279. When viewed from the front side of the mounting direction, the blocking portion 329 overlaps the winding side tube portion 277 and the winding side tube portion 279 from the back side of the mounting direction to the front side of the mounting direction so as to overlap the imaginary line 327 between the tubes. Integrated. The blocking portion 329 is only required to block the space between the take-up side tube portion 277 and the take-up side tube portion 279, and it may not overlap with the inter-tube imaginary line 327 when viewed from the front side in the installation direction, The exit-side cylindrical portion 277 and the take-up-side cylindrical portion 279 are separate members. Further, a cylindrical convex portion 331 protruding from the peripheral surface of the second ink ribbon 213 downstream of the first ribbon guide 281 in the conveying direction is provided on the take-up-side cylindrical portion 277. The cylindrical convex portion 331 extends in the axial direction of the take-up-side cylindrical portion 277 and is provided over substantially the entire axial direction of the take-up-side cylindrical portion 277. Moreover, it is preferable that the cylindrical convex part 331 is formed so that it may protrude as much as possible in the range which does not contact the 2nd ink ribbon 213.

As described above, the first guide body 289 of the first ribbon guide 281 is in contact with the ink surface 213a of the second ink ribbon 213. Therefore, when the second ink ribbon 213 is conveyed, the ink surface 213a of the second ink ribbon 213 and the peripheral surface of the first guide body 289 may rub against each other, which may cause ribbon shavings from the second ink ribbon 213. If the generated ribbon dust spreads into the second cassette case 209, the ribbon dust adheres to the second ink ribbon 213 conveyed from the second winding core 205 to the second ribbon exposed portion 221, and further, adheres Ribbon shavings on the second ink ribbon 213 are attached to the thermal sensor head 27. For this reason, there is a possibility that a printed image may be blurred or smeared, and may cause poor printing.

The second ink ribbon 213 is attached between the portions 279. In addition, since the cylindrical convex portion 331 is provided on the take-up-side cylindrical portion 277, it is possible to suppress the ribbon chips from adhering to the second ink ribbon 213 from the + X side of the take-out-side cylindrical portion 277. In other words, the first ribbon guide 281 that is in contact with the ink surface 213a of the second ink ribbon 213 is surrounded by the take-up side tube portion 279, the blocking portion 329, the take-out side tube portion 277, and the tube convex portion 331. Can form a capture area that captures the ribbon debris generated by the first ribbon guide 281. This can suppress printing defects such as blurring or smearing of the printed image. In addition, the height of the blocking portion 329, that is, the size in the mounting direction, is substantially the same as the height of the unwinding side tubular portion 277 and the winding side tubular portion 279, but it is not limited to this. That is, the height of the blocking portion 329 may be lower than the height of the take-up side tube portion 277 or the take-up side tube portion 279, or may be higher than the height of the take-up side tube portion 277 or the take-up side tube portion 279. height.

The roll-up vertical portion 335 is substantially perpendicular to the back wall portion 269. That is, the inclination angle of the take-up-side inclined portion 333 inclined from the angle perpendicular to the back side wall portion 269 is smaller than the inclination angle of the take-up side inclined portion 333 from the angle perpendicular to the back side wall portion 269. In addition, the inclination angle of the roll-up vertical portion 335 may be zero. That is, the take-up side vertical portion 335 may not be inclined from an angle perpendicular to the back side wall portion 269, but may be perpendicular to the back side wall portion 269. The inner side wall portion 269 is an example of the "tube protruding wall portion" of the present invention.

The take-up-side cylindrical portion 277 guides the second ink ribbon 213 in the take-up-side vertical portion 335. Therefore, the second ink ribbon is conveyed in a state where the width direction of the second ink ribbon 213 is substantially parallel to the rotation axis of the second ink core 205 between the second ink core 205 and the second ribbon exposed portion 221. 213 method, the second ink ribbon 213 is guided. Thereby, the occurrence of wrinkles in the second ink ribbon 213 can be suppressed. In addition, since the unwinding-side inclined portion 333 is provided in the unwinding-side cylindrical portion 277, it is possible to appropriately release the mold when the back-side casing 229 is formed.

Similarly to the take-up-side tubular portion 277, a take-up-side inclined portion 337 and a take-up-side vertical portion 339 are provided on the circumferential surface of the take-up-side tubular portion 279 in the circumferential direction of the take-up-side tubular portion 279. That is, in FIG. 10 and FIG. 11, a relatively thick line in the contour line of the winding side cylindrical portion 279 is strictly expressed as a contour line of an end portion near the front side of the installation direction of the winding side cylindrical portion 279 and The portion indicated by the double line representing the outline of the end portion in the mounting direction is the winding-side inclined portion 337, and the portion indicated by the relatively thin line is the winding-side vertical portion 339.

When the winding-side inclined portion 337 is viewed from the front side in the mounting direction, the winding-side inclined portion 337 is inclined toward the center side of the winding-side tubular portion 279 with respect to the back side wall portion 269 as it goes toward the mounting side. The winding-side vertical portion 339 is substantially perpendicular to the back-side wall portion 269. That is, the inclination angle of the take-up side vertical portion 339 inclined from the angle perpendicular to the back side wall portion 269 is smaller than the inclination angle of the take-up side inclined portion 337 inclined from the angle perpendicular to the back side wall portion 269. In addition, the inclination angle of the winding-side vertical portion 339 may be zero. That is, the winding-side vertical portion 339 may not be inclined from an angle perpendicular to the back side wall portion 269, but may be perpendicular to the back side wall portion 269.

The winding-side cylindrical portion 279 guides the second ink ribbon 213 to the winding-side vertical portion 339. Therefore, the second ink ribbon is conveyed between the second ink ribbon exposed portion 221 and the second winding core 207 in a state where the width direction of the second ink ribbon 213 is substantially parallel to the rotation axis of the second winding core 207. 213 method, the second ink ribbon 213 is guided. Thereby, the occurrence of wrinkles in the second ink ribbon 213 can be suppressed. In addition, since the winding-side inclined portion 337 is provided in the winding-side cylindrical portion 279, it is possible to appropriately release the mold when the rear case 229 is formed. Furthermore, the angle occupied by the winding-side vertical portion 339 in the circumferential direction of the winding-side cylindrical portion 279 is not particularly limited, but it is preferably as small as possible within a range where the second ink ribbon 213 can be appropriately guided. The reason is that the smaller the angle occupied by the winding-side vertical portion 339, the larger the angle occupied by the winding-side inclined portion 337 correspondingly, and the demolding can be appropriately performed.

As described above, the ribbon cassette 200 of the present embodiment includes the second take-up core 207, the take-up side tube portion 279, the first ribbon guide 281, and the second ribbon guide 283. The take-up side tube portion 279 guides the second ink ribbon 213 and is inserted into the first take-up shaft 31 when it is attached to the second cassette attachment portion 7. The first ink ribbon guide 281 guides the second ink ribbon 213 at a position further downstream than the take-up side cylinder portion 279 in the conveying direction. The second ink ribbon guide 283 guides the second ink ribbon 213 at a position further downstream than the first ink ribbon guide 281 in the conveyance direction.
