BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tape printing apparatus for printing using an adhesive tape having an adhesive layer on one surface.

[0002]

2. Description of the Related Art Recently, demand for a tape printing apparatus for printing on a printing tape has been increasing. However, the printing tape used in the conventional tape printing apparatus has a double-sided adhesive tape or an adhesive layer formed by applying an adhesive applied on the opposite side of the printing surface of the tape base material, and a release tape is attached on the back side. Or a tape in which a transparent tape for protection is adhered on the printing surface of the tape base material. As described above, the conventional tape-wrapped body has a multi-substrate multi-layer structure in many cases and is expensive, and the cost performance is not always satisfactory.

Therefore, development of an apparatus capable of printing on inexpensive tape has been desired.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and, in particular, to provide an adhesive tape printing apparatus for printing using an adhesive tape having no release tape.

[0005]

Means for Achieving the Object To achieve the above object, an adhesive tape printing apparatus according to the present invention is a tape winding device in which an adhesive tape having an adhesive layer exposed on a side opposite to a printing surface of a tape base material is wound. An adhesive tape printing apparatus using a packaging body, wherein the apparatus body has passed a print head, a platen provided at a position facing the print head, and a print head and a platen that overlapped with an ink ribbon. A pair of feed rollers for feeding the adhesive tape to the tape discharge side of the apparatus body, and a tape guide for receiving the adhesive layer of the adhesive tape guided by the feed rollers and guiding the tape in the discharge direction, and forming the platen into a small diameter. The feed roller on the side receiving the adhesive layer of the adhesive tape and the receiving portion of the tape guide are formed as a peeling surface that is easily peeled off from the adhesive layer.

A circumferential groove formed in a circumferential direction is provided on an outer peripheral surface of a roller of the feed roller on a side receiving the adhesive layer of the adhesive tape, and a circumferential groove is formed in the circumferential groove from a receiving portion of the tape guide. It is preferable to form the claw portion to be extended by extension.

[0007]

According to the above construction, printing is performed from the print head to the printing surface of the adhesive tape on the platen via the ink ribbon. At the same time, the adhesive tape is sent to a discharge side by a feed roller, and printing is sequentially performed according to the feed of the adhesive tape. After printing, the tape is guided to a tape guide via a feed roller and sent to the discharge side. After the predetermined printing is completed, the adhesive tape may be cut with a cutter.

According to the above printing apparatus, the platen is formed to have a small diameter and the adhesive tape is formed in such a size that the adhesive tape comes into contact with the print line portion of the print head with a minimum necessary area. The degree of adhesion of the adhesive layer is small,
Since the resistance to the feeding of the adhesive tape is reduced, good printing accuracy is maintained.

Further, since the roller of the feed roller on the side receiving the adhesive layer of the adhesive tape and the receiving portion of the tape guide are formed as peeling surfaces, a strong feeding force can be applied to the adhesive tape. In addition, the separation can be facilitated and the discharge can be ensured.

Further, since an inexpensive adhesive tape having only an adhesive layer formed on one surface of the tape substrate can be used, the printing cost can be greatly reduced.

A circumferential groove is formed in a circumferential direction on an outer peripheral surface of a roller of the feed roller which receives the adhesive layer of the adhesive tape, and a claw of a receiving portion of the tape guide is inserted into the circumferential groove. By configuring, the contact area between the outer peripheral surface of the roller and the adhesive layer of the adhesive tape is reduced, and the ridge including the lower roller and the claw portion is formed so as to be easily separated from the adhesive layer of the adhesive tape. As a result, the adhesive tape is discharged very smoothly.

As shown in FIG. 3, the tape winding body 2 is formed by winding an adhesive tape 10 having a transparent or opaque tape base material having an adhesive layer exposed on the side opposite to the printing surface, on an annular core material 11. .

The support portion 3 of the tape winding body 2 is rotatably provided on a rotating plate 13 which rotates around a support shaft 12.
The support rollers 14 are provided. The four support rollers 14 are arranged on a circumference having the same diameter as the inner diameter of the annular core material 11 of the tape winding body 2, and the tape winding body 2 is fitted to the outside of the support roller 14 in a fitted state. , So that it is rotatably supported.

The printing head 4 is a heat-sensitive printing means for thermally transferring characters, figures, and the like to the adhesive tape 10 and is connected to a printing device (not shown). A platen 5 is provided at a position facing the print head 4, and the print head 4 is provided so as to be constantly pressed against the platen 5 by a spring 15.

The platen 5 is made of an elastic material and has a small diameter, and is formed in such a size that the adhesive tape 10 contacts the print line portion of the print head 4 with a minimum area required.

The feed roller 8 comprises a pair of rollers 8a and 8b. As shown in FIG. 2, one roller 8a is formed as a soft roller and a groove such as a knurl is formed on the outer peripheral surface of the other roller 8b. Then, the contact surface of the adhesive tape 10 with the adhesive layer is reduced to form a peeling surface that is easy to peel. The outer peripheral surface of the roller 8b may be processed with Teflon. Further, three peripheral grooves 16 are formed in the circumferential direction on the outer peripheral surface of the lower roller. The feed roller 8 is connected to a rotation drive mechanism (not shown).

Next, the feed roller 8 is attached to the main body 1 of the apparatus.
The tape discharge section 17 is formed in the vicinity of the
Is provided with a cutter 18 for cutting the tape. Then, from the feed roller 8 via the discharge unit 17, the discharge unit 17
A tape guide 9 is arranged at a position extending outside the tape guide.

The tape guide 9 guides the ejection of the printed adhesive tape 10 sent from the feed roller 8, and serves as a receiving portion for the adhesive layer of the adhesive tape 10 on the plate-like body 9a. Are formed along the ridges 9b, and a part of each ridge 9b is extended to form a claw portion 19 protruding from one end of the plate-like body 9a. The claw portion 19 is disposed so as to enter the circumferential groove 16 of the lower roller of the feed roller 8, so that the peripheral surface of the roller 8 b apparently continues to the tape guide 9 via the claw portion 19. Formed. The ridge 9b is also formed as a release surface that is easily peeled off from the adhesive layer of the adhesive tape 10 by coating a fluorine resin or a silicone resin.

Further, on both sides of the print head 4, mounting shafts 7 for a take-up reel and a take-up reel of the ink ribbon 6 are arranged.

Next, the usage of the printing apparatus having the above configuration will be described. First, the ink ribbon 6 is passed between the platen 5 and the print head 4 before printing. Then, after the tape winding body 2 is fitted into the outside of the support roller 14 in a fitted state, the start end of the adhesive tape 10 is overlapped with the ink ribbon 6, passed between the platen 5 and the print head 4, and further fed. It is allowed to pass between the rollers 8.

When the printing device is operated in this way,
Printing is performed from the print head 4 to the printing surface of the adhesive tape 10 supported on the platen 5 via the ink ribbon 6. At the same time, the adhesive tape 10 is sent to the discharge side with the rotation of the feed roller 8 operated by the rotation drive mechanism, and printing is performed sequentially according to the feed speed of the adhesive tape 10. Since the platen 5 is formed in a small diameter and easily peels off from the adhesive layer of the adhesive tape 10, the platen 5 is fed by the feed force of the feed roller 8 between the rollers 8 a and 8 b by the feed force of the feed roller 8, and is sent out in the discharge direction. It is. Since the upper roller is soft, the contact surface with the adhesive tape 10 becomes large, and a large feeding force can be obtained for the adhesive tape 10. Further, the fed tape is immediately guided from the claw portion 19 of the tape guide 9 on the ridge 9b in the discharge direction, and is discharged from the discharge portion 17. Since the peripheral groove 16 is formed in the lower roller, the contact area between the outer peripheral surface of the lower roller and the adhesive layer of the adhesive tape 10 is small. Similarly, the contact area with the adhesive layer of the adhesive tape 10 is similarly small since the contact is made only with the lower roller and the claw portion 19.
Is formed so as to be easily peeled off from the adhesive layer of the adhesive tape 10, so that the adhesive tape 10 is discharged very smoothly. After the predetermined printing is completed, the adhesive tape 10 may be cut by the cutter 18.

According to the above-described printing apparatus, the platen 5 is formed to have a small diameter, and the adhesive tape 10 is formed to have such a size that the adhesive tape 10 contacts the print line portion of the print head 4 with a minimum area required. Since the degree of adhesion of the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape 10 is small and the resistance to the feeding of the pressure-sensitive adhesive tape 10 is reduced, good printing accuracy is maintained.

The adhesive tape 10 of the feed roller 8
The roller 8b on the side receiving the pressure-sensitive adhesive layer and the receiving portion (protrusion 9b) of the tape guide 9 are formed as peeling surfaces, so that a strong feeding force can be applied to the pressure-sensitive adhesive tape 10 and peeling is facilitated. Discharge can be assured.

Furthermore, since an inexpensive pressure-sensitive adhesive tape 10 in which only one surface of a tape substrate is provided with a pressure-sensitive adhesive layer can be used, printing costs can be greatly reduced.

Incidentally, the tip of the tape guide 9 is
And the feed roller 8, the tip of the adhesive tape 10 is always guided by at least the tip side of the tape guide 9 and comes to the position of the cutter 18.
Peeling from the feed roller 8 is performed smoothly. Therefore, the configuration may not be such that the leading end of the tape guide 9 enters the circumferential groove 16 of the feed roller 8.

Further, the tape guide 9 may be constituted by a peelable belt wound between a lower roller of the feed roller 8 and a roller (not shown) arranged outside the discharge section 17. .
