Detailed Description

Hereinafter, an embodiment of a printing system including a tape printing apparatus and a winding apparatus will be described with reference to the drawings attached hereto. In the following drawings, an XYZ rectangular coordinate system is shown to clarify the arrangement relationship of each part, but it goes without saying that the present invention is not limited to any one. The numerical values indicating the number of the components and the like are merely examples, and do not limit the present invention at all.

[ outline of the tape printing apparatus and the winding apparatus ]

The outline of the tape printing apparatus 101 and the winding apparatus 201 constituting the printing system Sy will be described with reference to fig. 1 and 2. The tape printing apparatus 101 prints a tape 401 (see fig. 3), and feeds the printed tape 401 to the winding apparatus 201. The winding device 201 winds the tape 401 conveyed from the tape printing device 101. The belt 401 is an example of the "continuous medium" of the present invention.

The tape printing apparatus 101 includes an apparatus housing 103 and an attachment cover 105. The device case 103 is formed in a substantially rectangular parallelepiped shape. The device case 103 is provided with a tape inlet 107 on the + X side surface and a tape outlet 109 on the-X side surface. The tape 401 is introduced into the tape introduction port 107 from the outside of the tape printing apparatus 101. The printed tape 401 is discharged from the tape discharge port 109. A cartridge mounting portion (not shown) is provided on the + Z side surface of the device case 103. The mounting portion cover 105 is provided on the + Z side of the device case 103 so as to be rotatable about the + Y side end portion. The mounting section cover 105 opens and closes the cartridge mounting section. A ribbon cartridge (not shown) containing an ink ribbon is detachably mounted in the cartridge mounting portion.

The apparatus housing 103 is provided with a platen shaft 113, a thermal head (not shown), and a feed motor 121 (see fig. 7). A platen roller (not shown) is rotatably attached to the platen shaft 113. When the feed motor 121 is operated, the platen roller is rotated, and the tape 401 and the ink ribbon sandwiched between the thermal head and the platen roller are fed. At this time, heat is generated by the thermal head, and printing is performed on the tape 401.

The winding device 201 is provided on the tape ejection port 109 side of the tape printing apparatus 101. The winding device 201 includes a base 203, a winding unit 205, and a winding guide 207.

The base portion 203 has a smaller dimension in the Z direction than the apparatus housing 103 of the tape printing apparatus 101, and is formed in a substantially rectangular parallelepiped shape. Further, a surface on the + Z side of the base portion 203 is provided with a grip portion 267 of the dial 251 in a rotatable manner. Although details will be described later, the user can move the winding portion 205 in the Z direction by rotating the dial 251 by pinching the pinch portion 267.

The winding unit 205 winds the tape 401 fed from the tape printing apparatus 101. The winding unit 205 includes a winding body 209 and a winding attachment body 211. The take-up body 209 is rotatably provided on the + Z-side face of the base portion 203. The winding installation body 211 is detachably installed on the winding main body 209 and rotates integrally with the winding main 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 on the base portion 203 so that the first flange portion 215 is embedded in a circular opening 217 provided on the + Z side surface of the base portion 203. The roll mounting body 211 includes a second flange 219. The first flange portion 215 and the second flange portion 219 are formed in a substantially disc shape. The roll mounting body 211 is mounted on the roll body 209 such that the second flange part 219 faces the first flange part 215. The tape 401 conveyed from the tape printing apparatus 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" of the present invention.

The winding guide portion 207 is provided on the + Z-side surface of the base portion 203. The winding guide section 207 guides the tape 401 fed from the tape discharge port 109 of the tape printing apparatus 101 to the winding section 205. The winding guide 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 belt 401 conveyed from the belt discharge port 109 to the friction member 223. The friction member 223 applies frictional resistance to the belt 401, thereby suppressing the belt 401 from being stretched toward the winding portion 205. The second guide roller 225 guides the belt 401 conveyed from the friction member 223 to the take-up portion 205. The guide wall 226 prevents the belt 401 fed from the first guide roller 221 to the friction member 223 from slackening toward the winding portion 205. The second guide roller 225 may be provided or may not be provided according to the conditions such as the specification of the tape 401 and the take-up speed of the tape 401 by the take-up unit 205.

[ Belt ]

The belt 401 will be described with reference to fig. 3. In the belt 401, there are various belts different in width, for example, six kinds including a 9mm width, a 12mm width, an 18mm width, a 24mm width, and a 36mm width, and a 50mm width. Of these, the four widths, that is, the 9mm width, the 12mm width, the 18mm width, and the 24mm width, are conveyed in the tape printing apparatus 101 so that the center positions of the tapes 401 in the width direction are substantially aligned. Therefore, the positions of both ends of the tape 401 in the width direction are different for each width of the tape 401. Further, the positions of both ends of the tape 401 in the width direction are different from those of the other tapes 401 for the tapes 401 having a width of 36mm and a width of 50 mm.

[ Rolling Main body ]

The winding body 209 is explained based on fig. 4 to 6. The winding body 209 includes a flange-side engagement portion 227 in addition to the winding core portion 213 and the first flange portion 215 described above.

The winding core 213 is formed in a substantially cylindrical shape extending in the Z direction. Two engaging portion forming surfaces 229 are provided on the circumferential surface of the winding core portion 213. Five core-side engaging portions 231 (see fig. 6) are formed on each engaging portion forming surface 229 so as to be aligned in the extending direction of the winding core portion 213. The five core-side engaging portions 231 are provided at positions corresponding to the widths of the five belts 401 from 12mm to 50mm in width. The core-side engaging portion 231 is engaged with a lever-side engaging portion (not shown) of a lever 233 (see fig. 1) provided in the roll mounting body 211. The roll mounting body 211 is mounted to the roll main body 209 at a position corresponding to the width of the belt 401 by the engagement of the lever-side engagement portion with the core-side engagement portion 231.

The first flange portion 215 is provided on the-Z-side end portion of the winding core portion 213. The first flange portion 215 and the winding core portion 213 are integrally formed. At the center of the first flange portion 215, a shaft insertion hole 235 is provided. A take-up reel 237 extending in the Z direction is inserted into the reel 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 inserted into the shaft insertion hole 235 by the take-up shaft 237 so as to be positioned in the direction intersecting the extending direction of the take-up shaft 237, that is, in the X direction and the Y direction. The winding shaft 237 is fixed to the winding-side support plate 220 (see fig. 7) built in the base portion 203, and protrudes from the winding-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 an output gear 287 (see fig. 7). Further, the engagement 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 output gear 287 receives power from a feed motor 121 provided in the tape printing apparatus 101. 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-Z-side surface of the first flange portion 215 toward the-Z side. The engaging convex portion 243 is provided in a flange shape at the tip end portion of the flange-side engaging portion 227. The flange-side engagement portion 227 engages with a cam-side engagement portion 259 described later at the engagement convex portion 243.

[ Gear train and detection part ]

Based on fig. 7, a gear train provided in the tape printing apparatus 101 and the winding apparatus 201, and the detection unit 127 provided in the tape printing apparatus 101 will be described. The tape printing apparatus 101 includes a printing-side first gear train 129 and a printing-side second gear train 131. The gear on the input side of the first gear train 129 on the printing side is engaged with the gear on the output side of the feeding gear train 125, that is, the platen gear 133 that rotates integrally with the platen rotation member 123. The printing side first gear train 129 transmits power input from the feeding gear train 125 to a winding side first gear train 279 described later. The printing side second gear train 131 transmits power input from a winding side second gear train 281 to be described later to the detection rotor 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 rotary body 135 and a photo interrupter (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 sectors are radially provided. When the detection rotary 135 rotates, light emitted from the light emitting element of the photo interrupter 137 to the light receiving element is intermittently interrupted by the detection rotary 135. Thus, the photo interrupter 137 outputs a detection signal corresponding to the rotation speed of the detection rotary 135 to the control unit 139 provided in the tape printing apparatus 101. Although not shown, the control Unit 139 includes various memories such as a processor represented by a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). Further, a part of the gears of the printing side first gear train 129, the printing side second gear train 131, and the detecting portion 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 power input from the printing-side first gear train 129 to the winding portion 205. The winding-side first gear train 279 is provided with 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 disposed coaxially with each other. 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 take-up portion 205. Further, the output gear 287 is also meshed with a gear on the input side of the wind-up side second gear train 281. The winding-side second gear train 281 transmits 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 an unillustrated support plate incorporated in the base portion 203.

When the tape printing apparatus 101 and the winding-up apparatus 201 are connected, the gear on the output side of the printing-side first gear train 129 meshes with the gear on the input side of the winding-side first gear train 279, and the gear on the output side of the winding-side second gear train 281 meshes with the gear on the input side of the printing-side second gear train 131. 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 to the winding portion 205 via the feed gear train 125, the printing-side first gear train 129, and the winding-side first gear train 279.

Here, the reduction gear ratios of the feeding gear train 125, the printing-side first gear train 129, and the winding-side first gear train 279 are set so that the winding speed of the tape 401 by the winding portion 205 is faster than the transport speed of the tape 401 by the platen roller. Therefore, the tape 401 is wound on the winding portion 205 in a state where tension is applied to the tape 401. The output gear 287 engaged with the first flange 215 receives the tension of the belt 401 wound around the winding portion 205, and is rotated while being slid by the torque limiter 285. Thereby, a speed difference between the conveyance speed of the tape 401 by the platen roller and the take-up speed of the tape 401 by the take-up section 205 is absorbed. The output gear 287 rotates at a rotational speed corresponding to the rotational speed of the winding portion 205. Further, the winding unit 205 rotates with a fixed torque restricted by the torque limiter 285.

The power of the feed motor 121 is transmitted not only to the first flange portion 215 but also from the output gear 287 to the detection rotary body 135 via the winding-side second gear train 281 and the printing-side second gear train 131. Therefore, the detection rotor 135 rotates at a rotation speed corresponding to the rotation speed of the winding portion 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.

In this way, the winding device 201 can cause the tape printing apparatus 101 to detect the rotation speed of the winding unit 205 by transmitting the power of the output gear 287, which rotates at the rotation speed corresponding to the rotation speed of the winding unit 205, to the tape printing apparatus 101 by the winding-side second gear train 281 without providing a detection means for detecting the rotation speed of the winding unit 205. Further, as described above, the winding device 201 can rotate the winding portion 205 by transmitting the power input from the tape printing apparatus 101 to the winding portion 205 through the winding-side first gear train 279 without providing the driving source of the winding portion 205. With these configurations, the reliability of the winding device 201 can be improved without providing an electric circuit in the winding device 201.

[ Flange moving part ]

The flange moving portion 245 will be described with reference to fig. 4 to 6. The flange moving portion 245 is a member for moving the first flange portion 215 so as to be positionable in the Z direction, that is, the extending direction of the take-up reel 237. As described above, in the tape printing apparatus 101, the tape 401 is conveyed 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. Therefore, even in the winding device 201, the tape 401 is conveyed to the winding unit 205 in a state where the positions of both ends of the tape 401 in the width direction are different for each width of the tape 401. To cope with this, the winding device 201 includes a flange moving portion 245, and the flange moving portion 245 moves the winding portion 205 in the extending direction of the winding shaft 237 so that the first flange portion 215 is moved to six flange positions that can be positioned according to the width of the above-described six bands 401.

The flange moving portion 245 includes: a cylinder cam 247, a flange moving gear 249, a dial 251, and a hook 253.

The cylindrical cam 247 is configured to be rotatable about a rotation axis parallel to the extending direction of the take-up 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 main body 255 and the cam gear portion 257 are integrally formed.

The cam main body 255 is formed in a cylindrical shape. A groove-shaped cam side engaging portion 259 that surrounds the cam main body 255 for one circumference is provided on the circumferential surface of the cam main body 255. The flange-side engagement portion 227 described above 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 take-up shaft 237. Thereby, the first flange portion 215 to which the flange-side engagement portion 227 is fixed moves in the extending direction of the take-up reel 237 integrally with the flange-side engagement portion 227. The cylindrical cam 247 is an example of the "cam" of the present invention.

The cam side engagement portion 259 includes six cam side maintaining engagement portions 261 and six cam side moving engagement portions 263. The cam side maintaining engagement portion 261 and the cam side moving engagement portion 263 are alternately provided in the circumferential direction of the cam main body 255. That is, the cam-side moving engagement portion 263 is provided so that one cam-side maintaining engagement portion 261 is connected to the other cam-side maintaining engagement portion 261.

The six cam-side maintaining engagement portions 261 are provided at positions corresponding to the six flange positions described above in the extending direction of the take-up shaft 237. That is, when the cam-side engagement portion 259 engages with the flange-side engagement portion 227 at the cam-side maintaining engagement portion 261, the first flange portion 215 is located at one of the six flange positions. The cam-side maintaining engagement portion 261 is provided substantially parallel to a plane perpendicular to the extending direction of the take-up shaft 237. The cam-side maintaining engagement portion 261 has a predetermined length in the circumferential direction for engaging with the flange-side engagement portion 227. Thus, when the cylindrical cam 247 rotates, the first flange 215 is held at one flange position without moving in the extending direction of the take-up shaft 237 while the cam-side engaging portion 259 is engaged with the flange-side engaging portion 227 at the cam-side holding engaging portion 261.

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 take-up shaft 237. Therefore, when the cylindrical cam 247 rotates, the first flange portion 215 moves between one flange position and the other adjacent flange position while the cam-side engaging portion 259 engages with the flange-side engaging portion 227 in the cam-side moving engaging portion 263.

In this way, the cam side engagement portion 259 includes six cam side maintaining engagement portions 261 that maintain the first flange portion 215 at one flange position, and six cam side moving engagement portions 263 that move the first flange portion 215 between the one flange position and the adjacent other flange position, and thus can move the first flange portion 215 so as to be positioned at the six flange positions.

In the cam-side engaging portion 259, a wall portion on the + Z side of the two wall portions in the extending direction of the take-up shaft 237, that is, a wall portion on the first flange portion 215 side functions as the coming-off preventing portion 265. That is, the retaining portion 265 keeps the engagement convex portion 243 in a retaining state with respect to the cam-side engagement portion 259. Thus, when the roll body 209 is pulled toward the + Z side by the user, for example, the engagement convex portion 243 can be prevented from coming off the cam-side engagement portion 259.

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

The dial 251 is a member for operating the cylindrical cam 247. The dial 251 includes the above-described grip portion 267 and a dial main body 269. The dial body 269 is housed in the base portion 203, and is connected to the grip portion 267 so as to rotate integrally with the grip portion 267. The dial body 269 includes a dial cylinder portion 271 provided on the + Z side and a dial gear portion 273 provided on the-Z side. The dial cylinder portion 271 and the dial gear portion 273 are integrally formed. The dial cylinder portion 271 is formed in a substantially cylindrical shape, and six dial-side engagement recesses 275 are provided at equal intervals in the circumferential direction on the circumferential surface thereof. Therefore, the user can easily grasp the position of the dial 251, that is, the engagement position between the cam side maintaining engagement portion 261 and the flange side engagement portion 227. The dial gear portion 273 is formed in a disc shape having a smaller diameter than the dial cylindrical portion 271. The dial gear portion 273 is engaged with the flange moving gear 249. Therefore, when the user rotates the dial 251 by pinching the grip portion 267, the flange moving gear 249 rotates, and further, the cam gear portion 257 and the cylindrical cam 247 rotate. 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 an "operation portion" of the present invention.

The hook 253 is rotatably supported by a hook support shaft (not shown). A hook side engagement portion 277 is provided at the distal end of the hook 253. The hook 253 is biased by a hook spring, not shown, in a counterclockwise direction when viewed from the + Z side, that is, in a rotational direction in which the hook-side engagement portion 277 faces the rotational center of the dial body 269. Therefore, the rotation of the dial 251 is restricted by the hook 253 engaging with the dial-side engaging recess 275 provided in the dial cylindrical portion 271. Further, 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 restricting portion" of the present invention. The dial-side engaging recess 275 is an example of the "restriction engaging portion" of the present invention.

Here, the six dial-side engaging concave portions 275 correspond to the six cam-side maintaining engaging portions 261 provided on the cylindrical cam 247. That is, when the cam-side engaging portion 259 engages with the flange-side engaging portion 227 at the cam-side maintaining engaging portion 261, the dial-side engaging recess 275 is provided at a position where it engages with the hook 253 on the dial cylindrical portion 271. Thus, 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 maintaining engagement portion 261. Therefore, when the dial 251 is rotated to a rotational position where the hook 253 engages with the dial-side engagement recess 275, that is, to a rotational position where the rotation of the dial 251 is restricted by the hook 253, the cam-side engagement portion 259 engages with the flange-side engagement portion 227 at the cam-side maintaining engagement portion 261, and the first flange portion 215 moves to one flange position. In other words, the user can move the first flange portion 215 to one flange position by rotating the dial 251 to a rotational position at which the rotation of the dial 251 is restricted, that is, to a rotational position at which the click feeling is felt.

Further, the cylindrical cam 247 is restricted from rotating by the hook 253 via the dial body 269 and the flange movement gear 249. Therefore, when the winding portion 205 is rotating, the cylindrical cam 247 is prevented from rotating by the rotational force of the winding portion 205. Therefore, when the winding portion 205 is rotating, the first flange portion 215 is prevented from moving in the extending direction of the winding shaft 237 against the user's intention.

Then, the roll mounting body 211 is mounted on the roll main body 209 in accordance with the width of the tape 401, whereby the tape 401 fed from the tape printing apparatus 101 is guided by the first flange portion 215 and the second flange portion 219 and wound around the roll core portion 213 (see fig. 8 and 9).

As described above, the winding device 201 of the present embodiment includes: the take-up shaft 237, the take-up core 213, the first flange portion 215, the flange side engagement portion 227, and the flange moving portion 245. The take-up core 213 is rotatably provided on the take-up shaft 237. On the winding core 213, the tape 401 is wound. The first flange portion 215 is provided movably in the extending direction of the take-up shaft 237 with respect to the take-up shaft 237. The first flange portion 215 guides the tape 401 wound around the winding core portion 213 in the width direction of the tape 401. The flange-side engagement portion 227 is movable integrally with the first flange portion 215. The flange moving portion 245 includes a cylindrical cam 247. The cylindrical cam 247 is provided with a cam side engaging portion 259 which engages with the flange side engaging portion 227. The flange moving portion 245 is moved so that the first flange portion 215 can be positioned at a plurality of flange positions corresponding to the width of the belt 401.

According to this structure, when the cylinder cam 247 rotates, the first flange portion 215 moves so as to be positioned at a flange position corresponding to the width of the belt 401. Therefore, the first flange portion 215 can be easily moved to the flange position corresponding to the width of the belt 401.

[ modified examples ]

The present invention is not limited to the above-described embodiments, and it goes without saying that various configurations can be adopted within a scope not departing from the gist thereof. For example, the above embodiment can be modified to the following embodiment in addition to the above embodiment.

The "cam side engagement portion" of the present invention is not limited to the structure including the cam side maintaining engagement portion 261 and the cam side moving engagement portion 263 like the cam side engagement portion 259, and for example, the entire cam side engagement portion 259 may be obliquely crossed with respect to a plane perpendicular to the extending direction of the take-up shaft 237. That is, while the cylindrical cam 247 is rotating, the winding portion 205 may be configured to move in the extending direction of the winding shaft 237 at all times. In this structure, six dial-side engagement recesses 275 correspond to 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. Thus, when the hook 253 engages with the dial-side engagement recess 275, the first flange portion 215 is positioned at the flange position. Therefore, when the dial 251 is rotated to a rotational position at which the hook 253 engages with the dial-side engagement recess 275, the first flange portion 215 moves to the flange position. Therefore, even in this configuration, the user can move the first flange portion 215 to the flange position by rotating the dial 251 to the rotational position at which the rotation of the dial 251 is restricted.

The "continuous medium" in the present invention is not limited to a belt-like medium such as the belt 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 structure such as the winding core portion 213 and the first flange portion 215, and may be formed separately. In this case, the "flange portion" may be fixed to the "take-up core portion" or may be attached to the "take-up core portion" so as to be movable relative thereto.

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

The "flange side engaging portion" and the "cam side engaging portion" in the present invention are not limited to the structure in which the "flange side engaging portion" is convex and the "cam side engaging portion" is concave, such as the flange side engaging portion 227 and the cam side engaging portion 259, and for example, a structure in which the "flange side engaging portion" is concave and the "cam side engaging portion" is convex may be adopted.

The "restricting engagement portion" of the present invention is not limited to the structure provided in the dial 251 such as the dial-side engagement recess 275, and may be provided in the cylindrical cam 247, for example.

The "printing apparatus" according to the present invention may be applied to the tape printing apparatus 101 according to the present embodiment. That is, the tape printing apparatus 101 may have a configuration including the same components as the winding shaft 237, the winding core 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 printing apparatus 101 and the winding apparatus 201 may be integrated. The "printing device" of the present invention is not limited to a configuration for printing on a strip-like material, and may be a configuration for printing on a web, for example. The "printing portion" of the present invention is not limited to a member that performs printing by a thermal method, such as a thermal head, and may be a member that performs printing by an ink jet method, an electrophotographic method, or a dot impact method, for example.
