  Then, after taking out the printed adhesive tape roll R2 from the storage unit 4, the user peels off the printed adhesive tape 150 ″ wound around the printed adhesive tape roll R2 from the inner portion in the roll radial direction. After the cutting, the user attaches a printed adhesive tape 150 ″ having a desired length to an appropriate adherend (via the adhesive layer 152), for example, a label or a package. It can be used as a sealing material.

<Control system of adhesive tape printer>
Next, the control system of the adhesive tape printer 1 will be described with reference to FIG.

  As shown in FIG. 6, the adhesive tape printing apparatus 1 includes a CPU 212 that constitutes a calculation unit that performs a predetermined calculation.

  The CPU 212 is connected to the RAM 213 and the ROM 214, and controls the entire adhesive tape printing apparatus 1 by performing signal processing according to a program stored in advance in the ROM 214 while using the temporary storage function of the RAM 213.

  In the RAM 213, for example, print data in an image data format received from a personal computer or the like is converted into dot pattern data for forming an ink layer IK in a predetermined print area on the front side of the base material layer 151 of the base material tape 150 to be printed. An image buffer 213a is provided for developing and storing.

  The ROM 214 stores a control program for executing predetermined control processing.

  Further, the CPU 212 is connected to three motor drive circuits 218, 219, and 220, a head control circuit 221, a display unit 215 that performs an appropriate display, and an operation unit 216 that can be appropriately operated by a user.

  The motor drive circuit 218 performs drive control of the transport motor M1 that drives the transport roller 12. The motor drive circuit 219 controls the drive of the winding motor M2 that drives the winding mechanism 40. The motor drive circuit 220 controls the drive of the transport motor M3 that drives the transport roller 14.

  The head control circuit 221 controls the driving of the piezoelectric actuator provided in the inkjet head 10a according to the print data, and ejects ink from the nozzles.

  That is, the CPU 212 performs ink-jet printing on the front side of the base material layer 151 of the base material tape 150 to be printed via the head control circuit 221 according to the print data stored in the image buffer 213 a according to an appropriate control program stored in the ROM 214. The ink layer IK corresponding to the print data is formed by the head 10a.

<Effects of this embodiment>
As described above, the adhesive tape printer 1 of this embodiment is used with the adhesive tape cartridge TK attached. At the time of printing, the ink layer IK is formed by the inkjet head 10a on the front side of the printing substrate tape 150 that is fed from the printing substrate tape roll R1 and conveyed by the conveyance roller 12 or the like. Thereafter, the coated tape 153 fed out from the coated tape roll R3 is bonded to the front side of the printed base tape 150 ′ on which the ink layer IK is formed by the conveying roller 14 and the sub-roller 14a, and the printed adhesive tape 150 is printed. ″ Is generated. The user attaches a printed adhesive tape 150 ”having a desired length to an appropriate adherend (via the adhesive layer 152 provided on the substrate tape 150 to be printed), For example, it is used as a sealing material for labels and packaging. At this time, as a result of the configuration as described above, the printed adhesive tape 150 ″ has the covering tape 153, the ink layer IK, the base material layer 151, and the adhesive layer 152 in this order from the front side to the back side. (Refer to the partially enlarged view d in FIG. 2.) By providing the covering tape 153 (covering layer 154) on the most front side of the printed adhesive tape 150 ″, the label or sealing is performed as described above. When used as a material, the printing is difficult to disappear due to rubbing of the surface, and the durability of the printing can be maintained.

  In the present embodiment, the printed adhesive tape 150 ″ is wound up by the winding mechanism 40 and is generated as the printed adhesive tape roll R2. As described above, the printed adhesive tape 150 ″ is the coated tape 153. , The ink layer IK, the base material layer 151, and the adhesive layer 152 in this order. Thus, in the generated adhesive tape roll R2 with print, the covering tape 153 and the adhesive layer 152 covering the front side of the ink layer IK Are in contact with each other in the roll radial direction (that is, the covering tape 153 is interposed between the ink layer IK and the adhesive layer 152) (see FIG. 5). As a result, the ink layer IK is moved to the adhesive layer 152 side when the printed adhesive tape 150 ″ is fed from the printed adhesive tape roll R2 and used, as in the case where the ink layer IK and the adhesive layer 152 are in direct contact with each other. Can be prevented from being adversely affected by being peeled off.

  As described above, in the present embodiment, it is possible to maintain the durability of printing when being used by being attached, and to prevent the printing from being adversely affected when being fed out from the printed adhesive tape roll R2. It is possible to realize the printed adhesive tape 150 ″ having the characteristics.

The covering tape 153 is interposed between the ink layer IK and the adhesive layer 152. Thus, when the printed adhesive tape 150 ″ is fed from the printed adhesive tape roll R2 and used, the ink layer IK becomes the adhesive layer 152. It is possible to prevent the ink from being peeled off to the side and adversely affecting the print quality (ink fading or the like occurs).

  In the present embodiment, in particular, in the sub-roller 14a, the four cylindrical contact portions 142 are discretely arranged apart from each other in the extending direction of the axis O4 (the sub-roller 14a is adhered over the entire length in the extending direction of the axis O4. Only the four cylindrical contact portions 142 contact the adhesive layer 152 (rather than contacting the layer 152). Thereby, since the contact area with the adhesion layer 152 at the time of conveyance of the said to-be-printed substrate tape 150 grade | etc., Can be made small, conveyance resistance can be reduced and smoother tape conveyance can be performed.

  In this embodiment, in particular, the covering tape 153 includes an adhesive layer 155 for bonding to the substrate material tape 150 to be printed on the back side. Thus, the adhesive tape 155 provided on the back side (in other words, the bonding side) of the covering tape 153 securely bonds the covering tape 153 and the substrate tape 150 to be printed to generate the printed adhesive tape 150 ″. be able to.

However, the present invention is not limited to this, and the substrate tape to be printed may include an adhesive layer for laminating the covering tape.

  Hereinafter, the configuration of the adhesive tape printer 1 of the present modification will be described with reference to FIG. In this modification, the same reference numerals are given to the same parts as those in the above embodiment, and the description will be omitted as appropriate.

  As shown in FIG. 7, in this modification, the substrate tape roll R1 to be printed is preliminarily wound around the axis O1 in place of the substrate tape 150A to be printed instead of the substrate tape 150 to be printed. It is turning.

  The substrate tape 150A to be printed includes the above-described base material layer 151, the above-described adhesive layer 152, and an adhesive layer 157 (corresponding to the second adhesive layer for bonding) formed of a predetermined adhesive. The printed substrate tape 150A has an adhesive layer 152, a base layer from the back side (upper left side in the partial enlarged view a in FIG. 7) to the front side (lower right side in the partial enlarged view a in FIG. 7). It has a laminated (three-layer) structure including the material layer 151 and the adhesive layer 157 in this order. The adhesive layer 157 is a layer for attaching a coating tape 153A described later to the substrate tape 150A to be printed.

  The transport roller 12A comes into contact with the printed substrate tape 150A (detailed printed substrate tape 150A ′, which will be described later) fed from the printed substrate tape roll R1 from the front side (ink layer IK side). In this modification, the sub-roller 12a comes into contact with the printed base tape 150A 'from the back side (adhesive layer 152 side). As a result, the transport roller 12A and the sub-roller 12a cooperate with the printed base tape 150A ′ (hereinafter referred to as “printed base tape 150A ′”) in between while holding the printed base tape 150A ′ therebetween. (Referred to as “printed substrate tape 150A etc.” as appropriate) in a tape orientation in which the tape width direction is the left-right direction.

  Further, in this modification, the ink jet head 10a is moved in accordance with the conveyance of the substrate tape 150A to be printed by the conveyance roller 12A, the sub-roller 12a, the conveyance roller 14, and the sub-roller 14a (hereinafter referred to as “conveyance roller 12A” as appropriate) Ink is ejected from the nozzle to the front side (adhesive layer 157 side) of the substrate tape 150A to be printed. As a result, the inkjet head 10 a forms the ink layer IK described above on the front side of the adhesive layer 157. The substrate tape 150A to be printed on which the ink layer IK is formed on the front side of the adhesive layer 157 is particularly referred to as “printed substrate tape 150A ′”.

  That is, the printed base tape 150A ′ has an adhesive layer 152, from the back side (upper left side in the partial enlarged view c in FIG. 7) to the front side (lower right side in the partial enlarged view c in FIG. 7). The substrate layer 151, the adhesive layer 157, and the ink layer IK are stacked (four layers) in this order.

  In this modification, the printed base tape 150A ′ and the covering tape 153A fed out from the covering tape roll R3 include the ink layer IK on the front side of the printed base tape 150A ′ and the covering tape 153A. In a state where the back side of (coating layer 154) is opposed, the sheet is bonded by being sandwiched between transport roller 14 and sub-roller 14a. Thereby, the conveyance roller 14 and the sub-roller 14a are bonded together by sandwiching the printed base tape 150A ′ and the covering tape 153A between them, and cooperate to cooperate with the substrate tape 150A to be printed and the covering. The tape 153A is conveyed in a tape posture in which the tape width direction is the left-right direction.

  As described above, the printed base tape 150A ′ and the covering tape 153A are bonded together by the transport roller 14 and the sub-roller 14a, in other words, the printed base tape 150A ′ having the ink layer IK formed on the front side. Further, the coated tape 153A is bonded to the front side, whereby the printed adhesive tape 150A ″ is generated.

  That is, the printed adhesive tape 150A ″ has a pressure-sensitive adhesive layer 152 and a base layer from the back side (upper left side in the partial enlarged view d in FIG. 7) to the front side (lower right side in the partial enlarged view d in FIG. 7). It has a laminated (five layers) structure including the material layer 151, the adhesive layer 157, the ink layer IK, and the coating layer 154 in this order.
