Description

  The present invention relates to a print label producing apparatus for producing a print label on which a desired print is formed.

  2. Description of the Related Art Conventionally, a print label producing apparatus has been proposed in which a tape to be printed is housed in a cartridge (cassette) in a roll shape, and desired characters are printed and discharged in a label form while the tape is fed out from the roll ( For example, Patent Document 1).

  In this prior art, a roll around which a base tape (double-sided adhesive tape) is wound, and a roll around which a print-receiving tape (film tape) to be bonded to the base tape is wound, these two rolls are used. Predetermined printing is performed on the print-receiving tape while each of the base tape and the print-receiving tape is fed out, and the print-receiving tape after printing and the base tape are bonded together to create a print label.

  At this time, a pressure-sensitive adhesive layer for bonding to the tape to be printed is provided on one side of the tape main body (base material layer) of the base tape, and on the opposite side of the tape main body, An affixing adhesive layer for affixing the label to the target is provided, and this agglutinating adhesive layer is covered with a template paper (peeling material layer) that is peeled off when affixing. As a result, in the print label after pasting the print-receiving tape and the base tape, the multilayer structure of the print-receiving tape, the sticking adhesive layer, the base material layer, the sticking adhesive layer, and the release material layer (In this example, it has a five-layer structure).

Japanese Patent Laid-Open No. 7-314831

  In recent years, the use of print labels has been diversified due to the expansion of the use of print labels, and print labels having various modes according to the use are desired. For example, when you want to attach a printed label to a curved outer peripheral surface (in other words, a convex surface) such as a writing instrument, sphere, wall surface, furniture, container, etc. with a rounded outer shape, or conversely, a glass ball, a basin There is a growing need to attach a print label to a curved inner peripheral surface (in other words, a concave surface) of a container or the like.

  However, in the print label formed in a multilayer structure by bonding the print-receiving tape and the base tape as in the prior art, the dimension in the thickness direction is relatively large. For this reason, when a printed label is affixed to a curved surface as described above, due to the effect of curvature, the tape surface direction between the print-receiving tape corresponding to the label surface side and the base tape corresponding to the opposite side thereof A force in the pulling direction or in the compressing direction acts along.

  That is, for example, when a print label is attached to the convex surface, a force in the compression direction acts on the adhesive layer for attaching the base tape, and a force in the tensile direction acts on the print-receiving tape. In this case, there is a concern that the force in the compression direction tends to cause wrinkles on the adhesive layer for application and peeling off from the convex surface to be applied.

  On the other hand, for example, when a print label is attached to the concave surface, a force in the tensile direction acts on the adhesive layer for attaching the base tape, and a force in the compression direction acts on the tape to be printed. In this case, the adhesive layer for application cannot follow the force in the tensile direction, and there is a concern that after application, the adhesive layer will be lifted from the convex surface to be applied and easily peeled off.

  As described above, the printed label produced by the above prior art is not specially considered for the case where it is applied to a curved surface such as a convex surface or a concave surface. However, there was a concern that the fit to the curved surface would worsen.

  An object of the present invention is to provide a printed label producing apparatus that can easily produce a printed label for curved surfaces that is difficult to peel off even when pasted on a curved surface and has a good fit to the curved surface after pasting.

  In order to achieve the above-mentioned object, the first invention is a print-receiving tape roll in which a print-receiving tape is wound so that the print-receiving tape can be unwound, a base material layer, and a sticking provided on one side in the tape thickness direction of the base material layer. Affixing adhesive layer, release material layer provided on one side of tape thickness direction of the adhesive layer for attachment, and tape to be printed provided on the other side of the base material layer in the tape thickness direction A base tape provided with a pressure-sensitive adhesive layer for bonding, and a base tape roll wound so that the base tape is fed out, and the base tape fed out from the base tape roll, A first laminating roller that constitutes one of a pair of laminating rollers for laminating the base tape and the print-receiving tape by applying a pressing force to the print-receiving tape that is fed from a printing tape roll A cartridge holder that is detachable from the tape cartridge, and a print head that performs desired printing on the print-receiving tape fed from the print-receiving tape roll of the tape cartridge mounted on the cartridge holder; The print head that is disposed so as to face the first laminating roller of the tape cartridge mounted on the cartridge holder and that is fed from the print-receiving tape roll to and from the first laminating roller The printed tape on which printing has been performed and the base tape fed out from the base tape roll are sandwiched and contacted with the print tape to act on the base tape side A second laminating roller constituting the other of the laminating roller pair, and the cart A first roller driving shaft that rotationally drives the first laminating roller of the tape cartridge mounted on the wedge holder, a second roller driving shaft that rotationally drives the second laminating roller, and the first laminating roller. The first feeding speed given by contacting the base tape while rotating and the second feeding speed given by contacting the print-receiving tape while rotating the second laminating roller are substantially different from each other. And a drive control means for driving the first roller drive shaft and the second roller drive shaft, respectively.

  The printed label producing apparatus of the first invention of this application includes a cartridge holder. When the tape cartridge is mounted in the cartridge holder, the base tape fed out from the base tape roll and the print-receiving tape fed out from the print-receiving tape roll and subjected to desired printing by the print head are bonded to the bonding roller. Pasted together in pairs. The bonding roller pair is configured by a first bonding roller provided in a tape cartridge mounted on the cartridge holder and a second bonding roller provided on the print label producing apparatus side. The first laminating roller and the second laminating roller are arranged so as to face each other, and sandwich the base tape and the print-receiving tape between each other. At this time, the first laminating roller comes into contact with the base tape and applies a pressing force toward the printing tape, and the second laminating roller comes into contact with the printing tape and applies a pressing force toward the base tape. Make it work. The first laminating roller is driven and rotated by a first roller driving shaft provided on the print label producing apparatus side when the tape cartridge is mounted in the cartridge holder, and the second laminating roller is driven by the second roller driving shaft. Has been rotated. As a result, of the base tape and the print-receiving tape to be bonded to each other, the base tape is brought into contact with the first laminating roller driven by the first roller drive shaft, and sent to the downstream side in the tape transport direction along with its rotation. It is. Further, the print-receiving tape is brought into contact with the second laminating roller driven by the second roller driving shaft, and is sent out to the downstream side in the tape conveying direction along with the rotation.

  Here, the print label producing apparatus according to the first aspect of the present invention includes drive control means for controlling the first roller drive shaft and the second roller drive shaft. The drive control means includes a first delivery speed when the first laminating roller contacts and feeds the base tape, and a second delivery speed when the second laminating roller contacts and feeds the print-receiving tape. Are controlled so as to have substantially different speeds.

  For example, when the first feeding speed is higher than the second feeding speed, the base tape and the print-receiving tape are bonded while being pressed between the first bonding roller and the second bonding roller as described above. In this case, the base tape is bonded to the print-receiving tape while being sent out at a higher speed than the print-receiving tape. That is, when viewed per unit time, the length of the base tape is longer than that of the print-receiving tape among the base tape and the print-receiving tape bonded to each other. As a result, the bonded tape (= base tape + printed tape) discharged after being bonded to the downstream side of the bonding roller pair has a shape warped toward the printed tape. Here, the base tape is provided with a release agent layer, a sticking adhesive layer, a base material layer, and a sticking adhesive layer from one side in the tape thickness direction, and the tape to be printed by the sticking adhesive layer. And pasted together. Therefore, the bonding tape includes a release agent layer, an adhesive layer for attachment, a base material layer, an adhesive layer for attachment, and a tape to be printed in this order from one side in the tape thickness direction. The print label produced using this bonding tape is attached to the object to be attached by the adhesive layer for application on the back side, with the print-receiving tape side being the front side. Here, when a print label is created using a bonding tape having a shape warped to the print-receiving tape side as described above, it is possible to have a concave shape in which the print-receiving tape side is the inside. Therefore, it is possible to easily produce a concave printed label suitable for attaching a concave surface, which is difficult to peel off even when applied to a concave surface, and has a good fit to the concave surface after application.

  On the other hand, for example, contrary to the above, when the second delivery speed is higher than the first delivery speed, the base tape is pressed between the first and second laminating rollers as described above. And the print-receiving tape are bonded to the base tape while being fed at a higher speed than the base tape. That is, when viewed per unit time, the length of the print-receiving tape is longer than that of the base-tape among the base-tape and the print-receiving tape that are bonded to each other. As a result, the bonded tape discharged to the downstream side of the bonding roller pair after being bonded has a shape warped to the base tape side. Therefore, when a print label is produced using a bonding tape having a shape warped to the base tape side, it can be made to have a convex shape such that the print-receiving tape side is the outside. Therefore, it is possible to easily create a convex printed label suitable for sticking a convex surface, which is difficult to peel off even when pasted on a convex surface and has a good fit to the convex surface after pasting.

  As described above, according to the printed label producing apparatus of the first invention of the present application, even when pasted on a curved surface such as a concave surface or a convex surface, it is difficult to peel off and the curved surface printing has a good fit to the curved surface after pasting. Labels can be created easily.

  According to a second aspect of the present invention, in the first aspect of the invention, the drive control means includes the first roller drive shaft and the first control shaft so that the first delivery speed is substantially higher than the second delivery speed. Each of the second roller drive shafts is driven.

  As a result, a bonded tape having a shape warped toward the print-receiving tape can be reliably generated, and therefore, a concave printed label suitable for concave bonding can be easily created using the bonded tape. Can do.

  According to a third invention, in the first invention, the drive control means includes the first roller driving shaft and the drive roller so that the second delivery speed is substantially larger than the first delivery speed. Each of the second roller drive shafts is driven.

  As a result, it is possible to reliably produce a bonding tape having a shape warped to the base tape side, and therefore, using this bonding tape, it is possible to easily create a convex print label suitable for convex bonding. Can do.

  In a fourth aspect based on the second or third aspect, the second laminating roller has substantially the same external dimensions as the first laminating roller of the tape cartridge, and the drive control means rotates By driving the first roller driving shaft and the second roller driving shaft so that the speeds have different values, the first feeding speed and the second feeding speed different from each other are realized.

  Thereby, two rollers can be used without changing the roller shape of the laminating roller with respect to the existing configuration in which the first feed speed on the base tape side and the second feed speed on the print-receiving tape side are substantially the same. Only by making the rotational speeds of the drive shafts different from each other, it is possible to realize a bonded tape having a shape warped to the print-receiving tape side or the base tape side. As a result, a concave print label or a convex print label can be easily produced.

  In a fifth aspect based on the second or third aspect, the second laminating roller has an outer dimension different from that of the first laminating roller of the tape cartridge, and the drive control means has a rotational speed. By driving the first roller drive shaft and the second roller drive shaft so as to be substantially the same, the first feed speed and the second feed speed different from each other are realized.

  As a result, the first feeding speed on the base tape side and the second feeding speed on the print-receiving tape side are approximately the same, and the pasting is performed without particularly changing the rotational speeds of the two roller drive shafts. By simply changing the roller shape of the alignment roller so that the roller diameters are different from each other, it is possible to realize a bonding tape having a shape warped toward the print-receiving tape or the base tape. As a result, a concave print label or a convex print label can be easily produced.

  In a sixth aspect based on the second or third aspect, the second laminating roller has substantially the same outer dimensions as the first laminating roller of the tape cartridge, and the gap between the second tape and the print-receiving tape. The friction coefficient is made of a material having a value substantially different from the friction coefficient between the first laminating roller and the base tape, and the drive control means has substantially the same rotational speed. By driving the first roller driving shaft and the second roller driving shaft in such a manner, the first feeding speed and the second feeding speed different from each other are realized.

  Thereby, the rotational speed and the roller diameter of the two roller drive shafts are particularly changed with respect to the existing configuration in which the first delivery speed on the base tape side and the second delivery speed on the print-receiving tape side are substantially the same. In addition, a bonding tape having a shape warped toward the print-receiving tape or the base tape can be realized only by changing the materials of the two bonding rollers to make the friction coefficients different from each other. As a result, a concave print label or a convex print label can be easily produced.

  According to the present invention, it is possible to easily create a printed label for curved surfaces that is difficult to peel off even when pasted on a curved surface and has a good fit to the curved surface after pasting.

The platen roller 182 is disposed at a position facing the thermal head 16 provided on the right side surface of the heat sink 15. As described above, the platen roller 182 rotates when the driving force from the motor 21 is transmitted to the platen roller gear 181 and the roller shaft 183 rotates. Thus, when the platen roller unit 18 moves to the printing position, the platen roller 182 presses the cover film 51 and the ink ribbon 55 against the thermal head 16, and characters, figures, symbols, etc. are printed. The cover film 51 is conveyed in the direction of the pressing roller unit 19 by its rotation.

  The pressure roller unit 19 is provided with a pressure roller 192 and a pressure roller gear 191. The pressing roller 192 is disposed at a position facing the roller shaft 20. The pressing roller 192 rotates when the driving force from the motor 21 is transmitted to the pressing roller gear 191 and the roller shaft 193 rotates. Thus, when the pressing roller unit 19 moves to the printing position, the pressing roller 192 presses the cover film 51 and the base tape 53 against the tape transport roller 39 that is rotatably supported by the roller shaft 20. To do. As a result, as described above, the printed cover film 51 and the base tape 53 are pressure-bonded to form a printed label tape 80, which is discharged from the tape discharge slit 24 to the outside of the hand-held type print label producing apparatus 1. The

  The greatest feature of the handy type print label producing apparatus 1 configured as described above is that, as described above, the tape conveying roller 39 and the pressing roller 192 are driven at substantially the same rotational speed, and the tape conveying roller 39 and the pressing roller are driven. By setting the outer diameters of 192 to different values, the feeding speeds are set to different values.

  FIG. 5 is a plan view showing the internal structure of the handheld type print label producing apparatus 1 with the detachable cover 6B2 removed. In the present embodiment, as shown in FIG. 4, the diameter of the tape transport roller 39 provided in the cartridge 31 is larger than the diameter of the pressing roller 192. Since the tape transport roller 39 and the pressure roller 192 are driven at substantially the same rotational speed as described above, the feed speed when the tape transport roller 39 contacts and feeds the base tape 53 (= roller peripheral speed; hereinafter appropriate). , The first delivery speed) is substantially higher than the delivery speed when the pressure roller 192 is brought into contact with the cover film 51 (= roller peripheral speed; hereinafter referred to as the second delivery speed as appropriate).

  In the above description, the motor drive circuit, the motor 21, and the gear mechanism including the second intermediate gear and the third intermediate gear function as drive control means described in each claim.

  As described above, in the handy type print label producing apparatus 1 of the present embodiment, the cartridge 31 is driven by the driving force of the platen roller 182, the pressing roller 192, and the tape transport roller 39 driven by the motor 21 when producing the print label. The cover film 51 is fed out from the cover film spool 52 and conveyed, and desired printing is performed by the print head 16. Further, the base tape 53 is fed out from the base tape spool 54 by the driving force and conveyed. The printed cover film 51 and the base tape 53 are guided between a tape transport roller 39 and a pressure roller 192 arranged so as to face each other, and between the tape transport roller 39 and the pressure roller 192. Pinched. The tape transport roller 39 contacts the base tape 53 and applies a pressing force toward the cover film 51, and the pressing roller 192 contacts the cover film 51 and applies a pressing force toward the base tape 53. As a result, the base tape 53 and the cover film 51 to be bonded to each other are bonded to generate a printed label tape 80, which is sent downstream in the tape transport direction.

  At this time, in this embodiment, the first delivery speed when the tape transport roller 39 contacts and feeds the base tape 53 is higher than the second delivery speed when the pressure roller 192 contacts and feeds the cover film 51. large. Thus, when the base tape 53 and the cover film 51 are bonded together while being pressed between the tape transport roller 39 and the pressing roller 192, the base tape 53 is fed out at a higher speed than the cover film 51. In this way, it is bonded to the cover film 51. That is, when viewed per unit time, the length of the base tape 53 is longer than that of the cover film 51 among the base tape 53 and the cover film 51 that are bonded to each other. As a result, the printed label tape 80 (bonding tape) discharged to the downstream side of the bonding roller pair after being bonded is warped to the cover film 51 side (left side in FIG. 5) as shown in FIG. Shape. That is, as shown in FIG. 5, the printed label tape 80 having a shape warped toward the cover film 51 is discharged from the tape discharge slit 24.

  Here, as described above, the base tape 53 includes a release agent layer 53a, an adhesive layer 53b for bonding, a base layer 53c, and an adhesive layer 53d for bonding along the tape thickness direction, The cover film 51 is bonded by the bonding adhesive layer 53d. Therefore, as shown in FIG. 6A, the printed label tape 80 has a release agent layer 53a, a sticking adhesive layer 53b, a base material layer 53c, and a sticking adhesive along the tape thickness direction. The agent layer 53d and the cover film 51 are provided in this order. As a result, the printed label L created using the printed label tape 80 is attached to the object to be attached by the adhesive layer 53d for attachment on the back side, with the cover film 51 side being the front side.

  When the printed label L is created using the printed label tape 80 having a shape warped toward the cover film 51 as shown in FIG. 5, as shown in FIG. It becomes the aspect which curved in the concave shape which makes the cover film 51 side the inner side. In this example, the case where the print R of “XX reagent sample ◯” is formed on the cover film 51 by mirror image printing is shown as an example.

  FIG. 7 shows an example in which the print label L is attached to the concave surface of the inner peripheral surface of the container V such as a beaker. Like the printed label L of this example, according to this embodiment, it is difficult to peel off even when applied to a concave surface, and also has a good fit to the concave surface after application, suitable for concave surface application. The print label L can be easily created.

  In this embodiment, in particular, the tape transport roller 39 of the cartridge 31 has a larger outer dimension than the pressing roller 192, and the tape transport roller 39 and the pressing roller 192 are driven so that the rotational speeds are substantially the same. By doing so, the first delivery speed is made larger than the second delivery speed. Thereby, for the existing configuration in which the first delivery speed on the base tape 53 side and the second delivery speed on the cover film 51 side are substantially the same, without particularly changing the rotational speed of the two roller drive shafts, Only by changing the roller shape of the tape transport roller 39 or the pressure roller 192 and changing the roller diameter, a label shape warped toward the cover film 51 can be realized. As a result, the concave printed label L can be easily created.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. Hereinafter, such modifications will be described in order.

(1) When creating printed labels for convex surfaces

  FIG. 8 is a plan view showing the internal structure of the cartridge 31 of the present modification, and corresponds to FIG. 4 of the above embodiment. As shown in FIG. 8, in this modification, the roller diameter of the tape transport roller 39 of the cartridge 31 is smaller than the roller diameter of the pressing roller 192. Further, the tape conveying roller 39 and the pressing roller 192 are driven at substantially the same rotational speed as in the above embodiment. Thus, the first delivery speed when the tape transport roller 39 contacts and feeds the base tape 53 is substantially smaller than the second delivery speed when the pressure roller 192 contacts and feeds the cover film 51. Become.

  In this case, when the base tape 53 and the cover film 51 are bonded together while being pressed between the tape transport roller 39 and the pressure roller 192, the base tape 53 is sent out at a slower speed than the cover film 51. In this way, it is bonded to the cover film 51. That is, when viewed per unit time, the length of the base tape 53 is shorter than that of the cover film 51 among the base tape 53 and the cover film 51 that are bonded to each other. As a result, as shown in FIG. 9 corresponding to FIG. 5 of the above embodiment, the printed label tape 80 (bonding tape) discharged to the downstream side of the bonding roller pair after being bonded is a base tape. The shape warps to the 53 side (right side in FIG. 9). That is, as shown in FIG. 9, the printed label tape 80 warped toward the base tape 53 side is discharged from the tape discharge slit 24.

  The printed label tape 80 in this case also has a release agent layer 53a, an adhesive layer 53b for attachment, and a base material along the tape thickness direction as shown in FIG. The layer 53c, the adhesive layer 53d for bonding, and the cover film 51 are provided in this order (however, along the base tape 53 side as described above). When the printed label L is created using the printed label tape 80 having a shape warped toward the base tape 53 as shown in FIG. 10A, the print label L is printed as shown in FIG. 10B. The label L is warped in a convex shape with the cover film 51 side as the outside. In this example, the case where the print R of “XX equipment number ○” is formed on the cover film 51 by mirror image printing is shown as an example.

  FIG. 11 shows an example in which the print label L is attached to the convex surface of the outer peripheral surface of a writing instrument P such as a pen or a pencil. Like the printed label L of this example, according to this modification, it is difficult to peel off even when applied to a convex surface, and also has a good fit to the convex surface after application, suitable for convex surface application. The print label L can be easily created.

  In this modification, the tape transport roller 39 of the cartridge 31 has an outer dimension smaller than that of the pressing roller 192 and is driven so that the rotation speeds of the tape transport roller 39 and the pressing roller 192 are substantially the same. Thus, the first delivery speed is made smaller than the second delivery speed. Thereby, for the existing configuration in which the first delivery speed on the base tape 53 side and the second delivery speed on the cover film 51 side are substantially the same, without particularly changing the rotational speed of the two roller drive shafts, Only by changing the roller shape of the tape transport roller 39 or the pressure roller 192 and changing the roller diameter, a label shape warped toward the base tape 53 side can be realized. As a result, the print label L for the convex surface can be easily created.

  (2) When creating convex print labels by changing the roller rotation speed

  In the above embodiment and the modification of (1), the external dimensions of the tape transport roller 39 of the cartridge 31 and the external dimensions of the pressure roller 192 are different, and the rotational speeds of the tape transport roller 39 and the pressure roller 192 are substantially the same. By driving in such a manner, the first delivery speed and the second delivery speed are different from each other. On the other hand, in this modified example, the rotational speed of the tape transport roller 39 is smaller than the rotational speed of the pressure roller 192 while the external dimensions of the tape transport roller 39 and the press roller 192 of the cartridge 31 are substantially the same. By driving in such a manner, the first delivery speed is made smaller than the second delivery speed.

  FIG. 12 is a plan view showing the internal structure of the cartridge 31 of this modification, and corresponds to FIG. 4 and FIG. As shown in FIG. 12, in this modification, the roller diameter of the tape transport roller 39 of the cartridge 31 is substantially the same as the roller diameter of the pressing roller 192. Unlike the above embodiment and the modified example (1), the tape transport roller 39 is driven at a lower rotational speed than the pressing roller 192.

  In the present modification, roller driving at different rotational speeds as described above is realized by changing the gear ratio in the power transmission path from the motor 21. FIG. 13 is an explanatory diagram conceptually showing a plurality of gears constituting the power transmission path of the motor 21 in this modification.

  In FIG. 13, a drive gear 21A (pinion) is fixed to the drive shaft of the motor 21 in this modification. The drive gear 21A is disposed on the front side of the motor storage cover via a cover opening provided in a motor storage cover (not shown). The drive gear 21A meshes with the main gear 211. Two transmission gears 212 and 213 mesh with the main gear 211. The transmission gear 212 meshes with another transmission gear 215, and this transmission gear 215 meshes with a pressure roller gear 191 provided on the roller shaft 193 of the pressure roller 192. On the other hand, the transmission gear 213 meshes with the tape transport roller gear 20 </ b> A provided on the roller shaft 20 of the tape transport roller 39 of the cartridge 31.

  When the motor 21 is driven with the cartridge 31 mounted in the cartridge holder 7, the two transmission gears 212 and 213 are rotated through the main gear 211, and the transmission gear 215 is rotated by the rotation of the transmission gear 212. Rotate. At this time, the pressure roller gear 191 has a smaller diameter than the tape conveying roller gear 20A. As a result, when the rotation is transmitted from the main gear 211 to the pressure roller gear 191 via the transmission gears 212 and 215, the gear ratio between the main gear 211 and the pressure roller gear 191 is changed from the main gear 211 to the transmission gear 213. And the gear ratio between the main gear 211 and the tape transport roller gear 20A when the rotation is transmitted to the tape transport roller gear 20A. Therefore, the pressure roller gear 191 rotates at a higher rotational speed than the tape transport roller gear 20A. As a result, the tape transport roller 39 is driven at a lower rotational speed than the pressing roller 192. As a result, the first delivery speed when the tape transport roller 39 contacts and feeds the base tape 53 is substantially smaller than the second delivery speed when the pressure roller 192 contacts and feeds the cover film 51. Become.

  In the above description, the motor drive circuit, the motor 21, and the gear mechanism including the main gear 211 and the transmission gears 212, 213, and 215 function as drive control means described in the claims.

  In the present modification, as described above, the first delivery speed when the tape transport roller 39 contacts and feeds the base tape 53 is higher than the second delivery speed when the pressure roller 192 contacts and feeds the cover film 51. Is also small. As a result, it is possible to easily create a convex print label L suitable for convex surface application that is difficult to peel off even when applied to a convex surface and has a good fit to the convex surface after application.

  Further, while the outer dimensions of the tape transport roller 39 and the outer dimensions of the pressing roller 192 are substantially the same, the rotational speed of the tape transport roller 39 is driven to be smaller than the rotational speed of the pressing roller 192. Thereby, the roller shape of the tape transport roller 39 or the pressure roller 192 is particularly changed with respect to the existing configuration in which the first delivery speed on the base tape 53 side and the second delivery speed on the cover film 51 side are substantially the same. Without reducing the rotation speed of one of the rotation speeds (the tape transport roller 39 in this example), the printed label tape 80 having a shape warped toward the base tape 53 can be realized. As a result, the print label L for the convex surface can be easily created.

(3) When creating concave print label by changing roller rotation speed In this modification, the outer dimensions of the tape transport roller 39 and the pressing roller 192 of the cartridge 31 are the same as the modification of (2) above. In contrast to the modification of (2) above, the second delivery speed is increased by driving the rotational speed of the tape transport roller 39 to be greater than the rotational speed of the pressing roller 192. Make it smaller than one feed speed.

  FIG. 14 is an explanatory diagram conceptually showing a plurality of gears constituting the power transmission path of the motor 21 in this modification, and is a diagram corresponding to FIG.

  In FIG. 14, as in FIG. 13, the drive gear 21 </ b> A is fixed to the drive shaft of the motor 21 in this modification, and the drive gear 21 </ b> A meshes with the main gear 211. However, in this modification, the diameter of the pressure roller gear 191 is increased and the tape transport roller gear 20A is reduced in diameter compared to the configuration of FIG.

  As a result, when the rotation is transmitted from the main gear 211 to the pressure roller gear 191 via the transmission gears 212 and 215, the gear ratio between the main gear 211 and the pressure roller gear 191 is changed from the main gear 211 to the transmission gear 213. And the gear ratio between the main gear 211 and the tape transport roller gear 20A when the rotation is transmitted to the tape transport roller gear 20A. Accordingly, when the motor 21 is driven with the cartridge 31 mounted in the cartridge holder 7, the tape transport roller gear 20 </ b> A rotates at a higher rotational speed than the pressure roller gear 191. As a result, the pressing roller 192 is driven at a lower rotational speed than the tape transport roller 39. As a result, the second delivery speed when the pressing roller 192 contacts and feeds the cover film 51 is substantially smaller than the first delivery speed when the tape transport roller 39 contacts and feeds the base tape 53. Become.

  In the above description, the motor drive circuit, the motor 21, and the gear mechanism including the main gear 211 and the transmission gears 212, 213, and 215 function as drive control means described in the claims.

  In the present modification, as described above, the second delivery speed when the pressure roller 192 contacts and feeds the cover film 51 is higher than the first delivery speed when the tape transport roller 39 contacts and feeds the base tape 53. Is also small. As a result, it is possible to easily create a printed label L for a concave surface suitable for attaching a concave surface, which is difficult to peel off even when attached to a concave surface and has a good fit to the concave surface after being attached.

  In this modification, the outer dimensions of the tape transport roller 39 and the outer dimensions of the pressure roller 192 are substantially the same, and the rotational speed of the pressure roller 192 is driven to be lower than the rotational speed of the tape transport roller 39. ing. Thereby, the roller shape of the tape transport roller 39 or the pressure roller 192 is particularly changed with respect to the existing configuration in which the first delivery speed on the base tape 53 side and the second delivery speed on the cover film 51 side are substantially the same. Without reducing the rotational speed of one of the rollers (in this example, the pressing roller 192), the printed label tape 80 having a shape warped toward the cover film 51 can be realized. As a result, the concave printed label L can be easily created.

(4) When a slippery roller material is used That is, as in the modified examples of (2) and (3) above, the outer dimensions of the tape transport roller 39 and the outer dimensions of the pressing roller 192 are substantially the same, and the pressing roller 192 is used. Instead of driving the rotation speed of the tape transport roller 39 different from that of the tape transport roller 39, the material of the tape transport roller 39 and the pressure roller 192 are made different from each other so that the slipperiness with the tape to be contacted is different. Also good.

  For example, although detailed illustration is omitted, the friction coefficient between the pressing roller 192 and the cover film 51 is made smaller than the friction coefficient between the tape transport roller 39 and the base tape 53. Specifically, the material of the roller main body (the part that contacts the cover film 51) of the pressing roller 192 is made of a synthetic resin material such as POM (polyoxymethylene) or ABS that has low sliding friction. At this time, the roller main body of the tape transport roller 39 (the portion in contact with the base tape 53) is made of a normal material having a large friction coefficient. In this case, in the contact between the pressing roller 192 and the cover film 51, slip is more likely to occur than in the contact between the tape transport roller 39 and the base tape 53. As a result, when viewed per unit time, the length of the base tape 53 of the base tape 53 and the cover film 51 to be bonded to each other is the same as in the above embodiment and the modified example of (3). Longer than 51. Accordingly, the first delivery speed when the tape transport roller 39 contacts and feeds the base tape 53 is substantially larger than the second delivery speed when the pressure roller 192 contacts and feeds the cover film 51. Become. As a result, similarly to the above, it is possible to easily create a printed label L for a concave surface suitable for attaching a concave surface, which is difficult to peel off when attached to a concave surface and has a good fit to the concave surface after application. it can.

  Further, for example, a configuration in which the friction coefficient between the tape transport roller 39 and the base tape 53 is made smaller than the friction coefficient between the pressing roller 192 and the cover film 51 is also conceivable. In this case, the material of the roller body of the tape transport roller 39 is a synthetic resin material such as POM or ABS, and the roller body of the pressing roller 192 is a normal material having a large friction coefficient. In this case, in the contact between the tape transport roller 39 and the base tape 53, slipping is more likely to occur than in the contact between the pressing roller 192 and the cover film 51. As a result, when viewed per unit time, the length of the cover film 51 of the base tape 53 and the cover film 51 to be bonded to each other is the same as in the modified examples (1) and (2). It becomes longer than the length of 53. Thus, the second delivery speed when the pressure roller 192 contacts and feeds the cover film 51 is substantially larger than the first delivery speed when the tape transport roller 39 contacts and feeds the base tape 53. Become. As a result, as in the modified examples of (1) and (2) above, even when applied to a convex surface, it is difficult to peel off, and the fit to the convex surface after application is good, and suitable for convex surface application. The print label L can be easily created.

  In the above, the contact portion of the motor drive circuit, the motor 21 and the base tape 53 or the cover film 51 of the tape transport roller 39 and the pressure roller 192, which are different materials as described above (the roller body). ) Functions as drive control means described in each claim.

  Further, in this modified example described above, the tape transport roller 39 or the pressure roller is compared with the existing configuration in which the first feed speed on the base tape 53 side and the second feed speed on the cover film 51 side are substantially the same. Without changing the rotation speed or the roller diameter of 192, the material of the tape transport roller 39 or the pressure roller 192 is changed to make the friction coefficients different from each other, so that the cover film 51 side or the base tape 53 side is warped. In this way, a printed label tape 80 having a different shape can be realized. As a result, the printed label L for concave or convex surfaces can be easily produced.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
