When the feed motor 121 is actuated, the platen roller rotates, and the tape 401 and the ink ribbon sandwiched between the thermal head and the platen roller are fed. At this time, the thermal head generates heat, and printing is performed on the tape 401.

The winding device 201 is installed on the tape outlet 109 side of the tape printer 101. The winding device 201 includes a base unit 203, a winding unit 205, and a winding guide unit 207.

The base portion 203 is formed in a substantially rectangular parallelepiped shape having a smaller dimension in the Z direction than the device case 103 of the tape printer 101. A knob 267 of the dial 251 is rotatably provided on the surface of the base 203 on the + Z side. Although details will be described later, the user can move the winding unit 205 in the Z direction by picking the knob 267 and rotating the dial 251.

The tape 401 sent from the tape printer 101 is wound on the winding unit 205. The winding unit 205 includes a winding main body 209 and a winding mounting body 211. The winding body 209 is rotatably provided on the + Z side surface of the base portion 203. The winding attachment 211 is detachably attached to the winding body 209 and rotates integrally with the winding body 209.

The winding body 209 includes a winding core portion 213 (see FIG. 4) and a first flange portion 215. The winding body 209 is provided in the base portion 203 such that the first flange portion 215 is embedded in a circular opening 217 provided on the surface of the base portion 203 on the + Z side. The winding attachment body 211 includes a second flange portion 219. The first flange portion 215 and the second flange portion 219 are formed in a substantially disc shape. The winding attachment body 211 is attached to the winding body 209 such that the second flange portion 219 faces the first flange portion 215. The tape 401 sent from the tape printer 101 is wound around the winding core portion 213 while being guided in the width direction of the tape 401 by the first flange portion 215 and the second flange portion 219. The first flange portion 215 is an example of the “flange portion” in the present invention.

The winding guide part 207 is provided on the surface on the + Z side of the base part 203. The winding guide unit 207 guides the tape 401 sent from the tape discharge port 109 of the tape printer 101 to the winding unit 205. The winding guide unit 207 includes a first guide roller 221, a friction member 223, a second guide roller 225, and a guide wall 226. The first guide roller 221 guides the tape 401 sent from the tape discharge port 109 to the friction member 223. The friction member 223 suppresses the tape 401 from being pulled toward the winding unit 205 by applying a frictional resistance to the tape 401. The second guide roller 225 guides the tape 401 sent from the friction member 223 to the winding unit 205. The guide wall 226 prevents the tape 401 sent from the first guide roller 221 to the friction member 223 from slacking to the winding unit 205 side. Note that the second guide roller 225 may or may not be provided depending on conditions such as the specification of the tape 401 and the winding speed of the tape 401 by the winding unit 205.

[tape]
The tape 401 will be described with reference to FIG. The tape 401 includes a plurality of types having different widths, and includes, for example, six types of 9 mm width, 12 mm width, 18 mm width, 24 mm width, 36 mm width, and 50 mm width. Of these, four types of 9 mm width, 12 mm width, 18 mm width, and 24 mm width are sent by the tape printer 101 such that the center positions in the width direction of the tape 401 are substantially matched. For this reason, the positions of both ends in the width direction of the tape 401 are different for each width of the tape 401. Also, the positions of both ends of the tape 401 in the width direction of the tape 401 having a width of 36 mm and a width of 50 mm are different from those of the other tapes 401.

[Winding body]
The winding body 209 will be described with reference to FIGS. The winding main body 209 includes a flange side engaging portion 227 in addition to the winding core portion 213 and the first flange portion 215 described above.

The winding core portion 213 is formed in a substantially cylindrical shape extending in the Z direction. Two engaging portion forming surfaces 229 are provided on the peripheral surface of the winding core portion 213. On each engagement portion forming surface 229, five core side engagement portions 231 are formed so as to be aligned in the extending direction of the winding core portion 213 (see FIG. 6). The five core side engaging portions 231 are provided at positions corresponding to the widths of five types of tapes 401 having a width of 12 mm to 50 mm. The lever side engaging portion (not shown) of the lever 233 (see FIG. 1) provided on the winding attachment 211 is engaged with the core side engaging portion 231. By engaging the lever side engaging portion with the core side engaging portion 231, the winding attachment body 211 is attached to the winding body 209 at a position corresponding to the width of the tape 401.

The first flange portion 215 is provided at the −Z side end of the winding core portion 213. The first flange portion 215 and the winding core portion 213 are integrally formed. A shaft insertion hole 235 is provided at the center of the first flange portion 215. A winding shaft 237 extending in the Z direction is inserted into the shaft insertion hole 235. The winding body 209 is supported by the winding shaft 237 so as to be rotatable and movable in the extending direction of the winding shaft 237. Further, the first flange portion 215 is positioned in the direction intersecting the extending direction of the winding shaft 237, that is, in the X direction and the Y direction, by inserting the winding shaft 237 into the shaft insertion hole 235. . The take-up shaft 237 is fixed to a take-up side support plate 220 (see FIG. 7) built in the base portion 203 and protrudes from the take-up side support plate 220 to the + Z side.

The first flange portion 215 includes a non-gear portion 239 on the + Z side and a flange gear portion 241 on the −Z side. The flange gear portion 241 meshes with the output gear 287 (see FIG. 7). Note that the meshing between the flange gear portion 241 and the output gear 287 is maintained even when the winding body 209 moves in the extending direction of the winding shaft 237. The power of the feed motor 121 provided in the tape printing apparatus 101 is transmitted to the output gear 287. That is, the winding unit 205 rotates using the feed motor 121 as a drive source. The winding unit 205 may be configured to rotate using a motor provided in the winding device 201 as a drive source.

The flange side engaging portion 227 is fixed to the first flange portion 215 so as to protrude from the approximate center of the surface on the −Z side of the first flange portion 215 to the −Z side. An engaging convex portion 243 is provided in a flange shape at the distal end portion of the flange side engaging portion 227. The flange side engaging portion 227 is engaged with a cam side engaging portion 259 described later at the engaging convex portion 243.

[Gear train and detector]
Based on FIG. 7, the gear train provided in the tape printer 101 and the winding device 201 and the detection unit 127 provided in the tape printer 101 will be described. The tape printer 101 includes a printing side first gear train 129 and a printing side second gear train 131. The input-side gear of the print-side first gear train 129 meshes with the output-side gear of the feed gear train 125, that is, the platen gear 133 that rotates integrally with the platen rotating member 123. The printing-side first gear train 129 transmits the power input from the feed gear train 125 to a winding-side first gear train 279 described later. The printing-side second gear train 131 transmits the power input from the winding-side second gear train 281 described later to the detection rotating body 135 of the detection unit 127.

The detection unit 127 detects the rotation speed of the winding unit 205. The detection unit 127 includes a detection rotating body 135 and a photo interrupter 137. As the detection unit 127, for example, a rotary encoder can be used. The detection rotating body 135 is formed in a plate shape in which a plurality of fan-shaped portions are provided radially. When the detection rotator 135 rotates, light emitted from the light emitting element of the photo interrupter 137 to the light receiving element is intermittently blocked by the detection rotator 135. Accordingly, the photo interrupter 137 outputs a detection signal corresponding to the rotation speed of the detection rotating body 135 to the control unit 139 provided in the tape printer 101. Although not shown, the control unit 139 includes a processor represented by a CPU (Central Processing Unit) and various memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory). Note that some of the gears of the printing-side first gear train 129, the printing-side second gear train 131, and the detection unit 127 are supported by the printing-side support plate 141.

The winding device 201 includes a winding side first gear train 279 and a winding side second gear train 281. The winding side first gear train 279 transmits the power input from the printing side first gear train 129 to the winding unit 205. The winding side first gear train 279 includes an intermediate gear 283, a torque limiter 285, and an output gear 287. The intermediate gear 283, the torque limiter 285, and the output gear 287 are coaxially provided. The torque limiter 285 is provided between the intermediate gear 283 and the output gear 287, and limits the torque transmitted from the intermediate gear 283 to the output gear 287 to a predetermined value. The output gear 287 meshes with the first flange portion 215 of the winding portion 205. The output gear 287 also meshes with the input side gear of the winding side second gear train 281. The winding side second gear train 281 transmits the power input from the output gear 287 to the printing side second gear train 131. The winding side first gear train 279 and the winding side second gear train 281 are supported by a support plate (not shown) built in the base portion 203.

When the tape printer 101 and the winding device 201 are connected, the output-side gear of the printing-side first gear train 129 meshes with the input-side gear of the winding-side first gear train 279, and the winding side The output-side gear of the second gear train 281 and the input-side gear of the print-side second gear train 131 are engaged. In this state, when the feed motor 121 provided in the tape printing apparatus 101 is operated, the power of the feed motor 121 is transmitted through the feed gear train 125, the print-side first gear train 129, and the take-up-side first gear train 279. Then, it is transmitted to the winding unit 205.

Here, the feed gear train 125, the printing side first gear train 129 and the take-up side are arranged so that the take-up speed of the tape 401 by the take-up unit 205 is faster than the feed speed of the tape 401 by the platen roller. The reduction ratio of the first gear train 279 is set. For this reason, the tape 401 is wound around the winding unit 205 in a state where tension is applied to the tape 401. The output gear 287 meshed with the first flange portion 215 receives the tension of the tape 401 wound around the winding portion 205 and rotates while slipping by the torque limiter 285. Thereby, the speed difference between the feeding speed of the tape 401 by the platen roller and the winding speed of the tape 401 by the winding unit 205 is absorbed. The output gear 287 rotates at a rotation speed corresponding to the rotation speed of the winding unit 205. The winding unit 205 rotates with a constant torque limited by the torque limiter 285.

The power of the feed motor 121 is not only transmitted to the first flange portion 215 but also transmitted from the output gear 287 to the detection rotating body 135 via the winding side second gear train 281 and the printing side second gear train 131. Is done. For this reason, the detection rotating body 135 rotates at a rotation speed corresponding to the rotation speed of the winding unit 205. Thereby, the detection unit 127 detects the rotation speed of the winding unit 205. That is, the control unit 139 acquires the rotation speed of the winding unit 205 based on the detection signal output from the photo interrupter 137.

Thus, the winding device 201 does not include a detection unit that detects the rotational speed of the winding unit 205, and the power of the output gear 287 that rotates at a rotational speed corresponding to the rotational speed of the winding unit 205 is By transmitting to the tape printing apparatus 101 by the winding side second gear train 281, it is possible to cause the tape printing apparatus 101 to detect the rotation speed of the winding unit 205. In addition, as described above, the winding device 201 does not include a drive source for the winding unit 205 itself, and the power input from the tape printer 101 is supplied to the winding unit 205 by the winding-side first gear train 279. The winding part 205 can be rotated by transmitting. With these configurations, the winding device 201 does not need to include an electric circuit, and the reliability of the winding device 201 can be improved.

[Flange moving part]
The flange moving unit 245 will be described with reference to FIGS. The flange moving part 245 is for moving the first flange part 215 so as to be positioned in the Z direction, that is, in the extending direction of the winding shaft 237. As described above, in the tape printer 101, the tape 401 is sent in a state where the positions of both ends in the width direction of the tape 401 are different for each width of the tape 401. For this reason, also in the winding device 201, the tape 401 is sent to the winding unit 205 in a state where the positions of both ends in the width direction of the tape 401 are different for each width of the tape 401. In order to cope with this, the winding device 201 winds the winding portion 205 so that the first flange portion 215 can be positioned at six flange positions corresponding to the widths of the six types of tape 401 described above. A flange moving part 245 for moving in the extending direction of the take-up shaft 237 is provided.

The flange moving part 245 includes a cylindrical cam 247, a flange moving gear 249, a dial 251 and a hook 253.

The cylindrical cam 247 is configured to be rotatable around a rotation axis parallel to the extending direction of the winding shaft 237. The cylindrical cam 247 includes a cam main body 255 provided on the + Z side and a cam gear portion 257 provided on the −Z side. The cam body 255 and the cam gear portion 257 are integrally formed.

The cam body 255 is formed in a cylindrical shape. On the peripheral surface of the cam main body 255, a groove-shaped cam-side engagement portion 259 that makes a round of the cam main body 255 is provided. The flange side engagement portion 227 is engaged with the cam side engagement portion 259. When the cylindrical cam 247 rotates, the flange side engaging portion 227 engaged with the cam side engaging portion 259 moves in the extending direction of the winding shaft 237. Accordingly, the first flange portion 215 to which the flange side engaging portion 227 is fixed moves in the extending direction of the winding shaft 237 integrally with the flange side engaging portion 227. The cylindrical cam 247 is an example of the “cam” in the present invention.

The cam side engagement portion 259 includes six cam side maintenance engagement portions 261 and six cam side movement engagement portions 263. The cam side maintenance engagement portion 261 and the cam side movement engagement portion 263 are alternately provided in the circumferential direction of the cam body 255. That is, the cam side movement engagement portion 263 is provided so as to connect one cam side maintenance engagement portion 261 and another cam side maintenance engagement portion 261.

The six cam-side maintenance engaging portions 261 are provided at positions corresponding to the six flange positions in the extending direction of the winding shaft 237. That is, when the cam side engaging portion 259 is engaged with the flange side engaging portion 227 in the cam side maintaining engaging portion 261, the first flange portion 215 is set to one flange position among the six flange positions. To position. Further, the cam side maintenance engagement portion 261 is provided substantially in parallel to a surface perpendicular to the extending direction of the winding shaft 237. Furthermore, the cam side maintenance engagement part 261 has a predetermined length for engaging with the flange side engagement part 227 in the circumferential direction. Accordingly, when the cylindrical cam 247 rotates, the first flange portion 215 is wound while the cam side engaging portion 259 is engaged with the flange side engaging portion 227 in the cam side maintaining engaging portion 261. One flange position is maintained without moving in the extending direction of the shaft 237.

On the other hand, the cam side moving engagement portion 263 is provided so as to obliquely intersect a plane perpendicular to the extending direction of the winding shaft 237. Therefore, when the cylindrical cam 247 rotates, while the cam side engaging portion 259 is engaged with the flange side engaging portion 227 in the cam side moving engaging portion 263, the first flange portion 215 is 1 Move between one flange position and another adjacent flange position.

As described above, the cam side engagement portion 259 has six cam side maintenance engagement portions 261 that maintain the first flange portion 215 at one flange position, and the first flange portion 215 that is adjacent to one flange position. By providing the six cam side movement engagement portions 263 that move between the first flange portion 215 and the second flange position, the first flange portion 215 can be moved to the six flange positions in a positionable manner.

Further, in the cam side engaging portion 259, of the two wall portions in the extending direction of the winding shaft 237, the + Z side wall portion, that is, the first flange portion 215 side wall portion functions as the retaining portion 265. is doing. That is, the retaining portion 265 keeps the engaging convex portion 243 from retaining with respect to the cam side engaging portion 259. Thereby, when the winding main body 209 is pulled to the + Z side by the user or the like, the engagement convex portion 243 is suppressed from being detached from the cam side engagement portion 259.

The cam gear portion 257 is formed in a disk shape having a smaller diameter than the cam body 255. The cam gear portion 257 meshes with the flange moving gear 249.

The dial 251 is for operating the cylindrical cam 247. The dial 251 includes the knob portion 267 and the dial body 269. The dial body 269 is accommodated in the base 203 and is connected to the knob 267 so as to rotate integrally with the knob 267. The dial main body 269 includes a dial cylindrical portion 271 provided on the + Z side and a dial gear portion 273 provided on the −Z side. The dial cylindrical portion 271 and the dial gear portion 273 are integrally formed. The dial cylindrical portion 271 is formed in a substantially cylindrical shape, and six dial side engaging recesses 275 are provided at equal intervals in the circumferential direction on the peripheral surface thereof. Therefore, the user can easily grasp the position of the dial 251, that is, the engagement position between the cam side maintenance engagement portion 261 and the flange side engagement portion 227. The dial gear portion 273 is formed in a disk shape having a smaller diameter than the dial cylindrical portion 271. The dial gear portion 273 meshes with the flange moving gear 249. Therefore, when the user picks the knob 267 and rotates the dial 251, the flange moving gear 249 rotates, and the cam gear 257 and the cylindrical cam 247 rotate. In addition, the six dial-side engagement recesses 275 are provided at equal intervals in the circumferential direction, but may not be provided at equal intervals. The dial 251 is an example of the “operation unit” in the present invention.

The hook 253 is rotatably supported by a hook support shaft (not shown). A hook side engaging portion 277 is provided at the tip of the hook 253. The hook 253 is applied with a force by a hook spring (not shown) in a counterclockwise direction when viewed from the + Z side, that is, in a rotation direction in which the hook side engaging portion 277 is directed toward the rotation center of the dial body 269. For this reason, the hook 253 restricts the rotation of the dial 251 by engaging with the dial-side engagement recess 275 provided in the dial cylindrical portion 271. As the hook spring, for example, a torsion coil spring provided on the hook support shaft can be used. The hook 253 is an example of the “operation restriction unit” in the present invention. The dial-side engagement recess 275 is an example of the “regulation engagement portion” in the present invention.

Here, the six dial side engagement recesses 275 correspond to the six cam side maintenance engagement portions 261 provided in the cylindrical cam 247. That is, when the cam side engaging portion 259 is engaged with the flange side engaging portion 227 in the cam side maintaining engaging portion 261, the dial side engaging concave portion 275 is located at a position where the dial cylindrical portion 271 is engaged with the hook 253. Is provided. As a result, when the hook 253 engages with the dial-side engagement recess 275, the cam-side engagement portion 259 engages with the flange-side engagement portion 227 at the cam-side maintenance engagement portion 261. For this reason, when the dial 251 rotates to the rotation position where the hook 253 engages with the dial-side engagement recess 275, that is, to the rotation position where the rotation of the dial 251 is restricted by the hook 253, the cam-side engagement portion 259 is moved. The cam side maintenance engagement portion 261 engages with the flange side engagement portion 227, and the first flange portion 215 moves to one flange position. In other words, the user moves the first flange portion 215 to one flange position by rotating the dial 251 to the rotation position where the rotation of the dial 251 is restricted, that is, the rotation position where the user feels a click feeling. Can do.

Further, the rotation of the cylindrical cam 247 is restricted by the hook 253 via the dial body 269 and the flange moving gear 249. For this reason, when the winding part 205 is rotating, it is suppressed that the cylindrical cam 247 rotates with the rotational force of the winding part 205. Therefore, when the winding part 205 is rotating, it is suppressed that the 1st flange part 215 moves to the extending direction of the winding shaft 237 contrary to a user's intention.

Furthermore, the tape 401 sent from the tape printer 101 is guided by the first flange portion 215 and the second flange portion 219 by attaching the winding attachment body 211 to the winding body 209 in accordance with the width of the tape 401. While being done, it is wound around the winding core portion 213 (see FIGS. 8 and 9).

As described above, the winding device 201 of this embodiment includes the winding shaft 237, the winding core portion 213, the first flange portion 215, the flange side engagement portion 227, and the flange moving portion 245. ing.

It goes without saying that the present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the spirit of the present invention. For example, the above-described embodiment can be changed to the following form in addition to the above.

The “cam-side engagement portion” of the present invention is not limited to the configuration including the cam-side maintenance engagement portion 261 and the cam-side movement engagement portion 263 as in the cam-side engagement portion 259. For example, The entire cam side engaging portion 259 may be configured to cross obliquely with respect to a plane perpendicular to the extending direction of the winding shaft 237. In other words, the winding unit 205 may always move in the extending direction of the winding shaft 237 while the cylindrical cam 247 is rotating. In this configuration, the six dial side engaging recesses 275 correspond to the six flange positions. That is, when the first flange portion 215 is located at the flange position, the dial-side engagement recess 275 is provided at a position where the dial cylindrical portion 271 engages with the hook 253. As a result, when the hook 253 engages with the dial-side engagement recess 275, the first flange portion 215 is positioned at the flange position. For this reason, when the dial 251 rotates to the rotation position where the hook 253 engages with the dial side engagement recess 275, the first flange portion 215 moves to the flange position. Therefore, also in this configuration, the user can move the first flange portion 215 to the flange position by rotating the dial 251 to the rotation position where the rotation of the dial 251 is restricted.

The “continuous medium” of the present invention is not limited to a tape-like one like the tape 401, and may be, for example, a roll paper. The length, width and material of the “continuous medium” are not particularly limited.

The “winding core portion” and the “flange portion” of the present invention are not limited to the integrally formed configuration, such as the winding core portion 213 and the first flange portion 215, and are formed separately. May be. In this case, the “flange portion” may be fixed to the “winding core portion”, or may be attached to the “winding core portion” so as to be movable.

The “cam” of the present invention is not limited to the cylindrical cam 247, and for example, a plate cam, a linear motion cam, or the like may be used.

The “flange side engaging portion” and the “cam side engaging portion” of the present invention, like the flange side engaging portion 227 and the cam side engaging portion 259, have a convex “flange side engaging portion” and a “cam”. For example, conversely, the “flange-side engaging portion” may be concave and the “cam-side engaging portion” may be convex.

The “regulatory engagement portion” of the present invention is not limited to the configuration provided in the dial 251 like the dial-side engagement recess 275, and may be a configuration provided in the cylindrical cam 247, for example.

The “printing apparatus” of the present invention may be applied to the tape printing apparatus 101 of the present embodiment. That is, the tape printing apparatus 101 may have a configuration similar to the winding shaft 237, the winding core portion 213, the first flange portion 215, the flange side engaging portion 227, and the flange moving portion 245 of the present embodiment. . In other words, the tape printer 101 and the winding device 201 may be integrated. The “printing apparatus” of the present invention is not limited to a configuration that performs printing on a tape-shaped device, and may be one that performs printing on roll paper, for example. In addition, the “printing unit” of the present invention is not limited to one that performs printing by a thermal method, such as a thermal head, and may perform printing by, for example, an inkjet method, an electrophotographic method, or a dot impact method.
