BACKGROUND OF THE INVENTION
The present invention relates to a technology of a label tape cartridge for a tape printer.
[0002]
[Prior art]
The technology of a label tape cartridge that is detachable from a tape printer has been conventionally known. In this label tape cartridge, a label tape is housed in a housing. An adhesive layer is formed on the surface opposite to the printing surface of the paper, and a release paper is pasted on the adhesive layer side. It is a combined structure.
[0003]
In addition, by changing the layout of the travel route by forming a plurality of storage sections in the cartridge that can be stored with the tape wound, and not arranging the tape in the storage section depending on the type of cartridge. A configuration that can cope with the above is known.
In this way, the versatility of cartridge parts (for example, the above-described housing) is increased, and the parts can be used in common for various types of cartridges. As a result, there are advantages that the types of parts can be reduced and the manufacturing cost can be suppressed.
[0004]
[Problems to be solved by the invention]
By the way, a plurality of labels having the same shape in the longitudinal direction of the tape can be obtained by using a label tape in which half-cut processing (usually die-cut processing) is performed on the printing-side paper. It can be set as the structure which arranged the part so that peeling was possible at equal intervals.
In this configuration, a desired image can be formed on the label portion by mounting the label tape cartridge on the tape printer and supplying the label portion together with the release paper to the print portion. The label tape after printing is discharged from a discharge port provided at an appropriate position of the apparatus, and the label portion is peeled off from the release paper in the discharged label tape and used by sticking it to a desired place as an adhesive label. it can.
[0005]
However, when a half-cut label tape is used for the above-described conventional configuration of the label tape cartridge, when the label tape crosses the housing portion, the label is placed on the wall portion arranged to surround the housing portion. There is a possibility that the tape is rubbed and the label portion is turned over in the cartridge and peeled off.
If the label part is peeled off in the cartridge in this way, the peeled label part adheres to a movable part such as a roller or the wall surface of the tape transport path in the cartridge, and a tape feeding defect occurs, and the label part Printing cannot be performed.

In other words, in addition to the above-described tape housing portion P2, the cartridge 30a includes a tape housing portion P1 centered on the second boss portion 52, and a tape housing portion P3 centered on the third boss portion 53, respectively. It is formed. Hereinafter, in order to identify each tape storage part, the code | symbol P1 is called a "first storage part", the code | symbol P2 is called a "second storage part", and the code | symbol P3 is called a "3rd storage part", respectively.
[0022]
The double tape 36 wound around the base material supply spool 37 in the first accommodating portion P1 is a double-sided adhesive tape having the same width as the laminate tape 31 and having an adhesive layer on both sides thereof, and peeling that is bonded to one side. Double structure with tape. The double tape 36 is wound around the outer periphery of the base material supply spool 37 with the side where the release tape is applied facing outward and the side where the adhesive layer is exposed facing inward. The laminate tape 31 is accommodated in the first accommodating portion P1.
[0023]
As described above, the joining roller 38 is rotatably supported in the housing 41. The joining roller 38 is configured to bond the double tape 36 from the base material supply spool 37 and the laminating tape 31 from the laminating spool 32 by pressure contact with a feeding roller 22 (described later) on the apparatus side.
In addition, a ribbon take-up spool 35 is rotatably supported in the housing 41 so that the ribbon take-up spool 35 takes up the used ink ribbon 33 supplied from the ribbon supply spool 34 described above. It is configured.
[0024]
On the other hand, on the cartridge mounting frame 11 side of the printing apparatus 2, the roller drive shaft 16 is located at a position corresponding to the joining roller 38, and the take-up drive shaft 15 is located at a position corresponding to the ribbon take-up spool 35. Be placed. When the tape cartridge 30a is mounted on the cartridge mounting frame 11, as shown in FIG. 3, the roller driving shaft 16 and the joining roller 38, and the winding driving shaft 15 and the ribbon winding spool 35 are Each engages.
[0025]
The printing apparatus 2 is provided with an electric motor (not shown), and the driving force of the electric motor is transmitted to the roller drive shaft 16 and the take-up drive shaft 15 via a gear train (not shown). As a result, the joining roller 38 and the ribbon take-up spool 35 on the tape cartridge 30a side can be driven via the drive shafts 16 and 15, respectively.
The tape drive printing mechanism 10 is formed on the printing device 2 side by these two drive shafts 16 and 15, the thermal head 13 and the feed roller 22 described below.
[0026]
As shown in FIG. 2, the arm 20 is attached to the cartridge mounting frame 11 so as to be swingable around the shaft 20a. A platen roller 21 and a feed roller 22 each having an elastic member such as rubber disposed on the surface thereof are provided side by side at the tip of the arm 20 and are rotatable.
A plate 12 projects from the cartridge mounting frame 11. When the tape cartridge 30 a is mounted at a predetermined position on the cartridge mounting frame 11, the plate 12 enters the recess 14 formed in the housing 41 and is positioned. Further, a thermal head 13 is disposed on the platen roller 21 side of the plate 12, and the thermal head 13 has a plurality of heating elements arranged in a line in the direction perpendicular to the paper surface of FIG.
[0027]
A biasing spring (not shown) is attached to the arm 20 described above, and a biasing force that moves the arm 20 downward in FIG. 2 is constantly applied.
Therefore, when the tape cartridge 30a is mounted on the cartridge mounting frame 11, as shown in FIG. 3, the platen roller 21 is in pressure contact with a thermal head 13 disposed on the plate 12 described later, and the feed roller 22 is a bonding roller. 38 is in pressure contact.
[0028]
The above is the configuration of the tape cartridge. Next, the state of printing using this tape cartridge will be described with reference to FIG.
The laminate tape 31 accommodated in the second accommodating portion P2 is pulled out to the location of the pin 61, and is superposed on the ink ribbon 33 pulled out from the ribbon supply spool 34 at the position of the pin 61. The laminated tape 31 and the ink ribbon 33 that are stacked on each other are sent from the pins 62 and 63 to the platen roller 21 and pressed against the thermal head 13, and the ink is selectively heated by the heating elements of the thermal head 13. The ink on the ribbon 33 is transferred to the laminate tape 31. As a result, desired images such as characters and symbols are printed on the laminate tape 31.
[0029]
After passing through the thermal head 13, the laminating tape 31 and the used ink ribbon 33 travel in two hands.
The laminating tape 31 is fed toward the feed roller 22, and at the same time, the double tape 36 drawn out from the first accommodating portion P1 is exposed to the adhesive layer exposed side (that is, the side where the release tape is not bonded). ) Toward the outside (feed roller 22 side). As a result, the laminating tape 31 and the double tape 36 are joined and adhered to each other by pressure contact between the feed roller 22 and the joining roller 38.
As a result, a label tape 8 having a three-layer structure in which a laminated tape 31 on which characters and symbols are recorded is provided on the double tape 36 is formed, and the label tape 8 is discharged from the discharge port 2b. Is done.
The tape cutting mechanism 17 provided in the vicinity of the discharge port 2b has a fixed blade 17a and a rotary blade 17b so that the label tape 8 after discharge can be cut and separated. The label tape 8 after cutting can be used as an adhesive label that can be attached to an arbitrary place by peeling the release tape.
[0030]
The used ink ribbon 33 that has passed through the thermal head 13 is sent from the pin 64 to the ribbon take-up spool 35, and taken up and collected.
[0031]
The laminating tape 31 and the double tape 36 are pulled out and run by driving the joining roller 38 via the roller driving shaft 16. The ink ribbon 33 is pulled out and traveled by driving the ribbon take-up spool 35 via the take-up drive shaft 15. As a result, it is not necessary to provide a driving mechanism on the tape cartridge 30a side, so that the manufacturing cost of the cartridge 30a can be reduced.
[0032]
[Configuration of half-cut thermal label type cartridge]
Next, the configuration of another type of tape cartridge that can be mounted on the cartridge mounting frame 11 will be described with reference mainly to FIGS. This tape cartridge (label tape cartridge) 30b is of a type that performs printing by causing the thermal head 13 to thermally develop a thermal tape label tape on which a plurality of label portions of a predetermined size are formed by half-cut processing. Is.
FIG. 4 shows an embodiment of the present invention. Reference example for It is the figure which showed a mode that the cartridge of the half cut thermosensitive label type which concerns on was set to a tape printer. Also, FIG. Of this reference example, It is the figure which showed the mode of the tape running in the said cartridge of the set state.
FIG. 6 is a perspective view showing the configuration of the thermal label tape. FIG. 7 is a perspective view showing the configuration of the heat-sensitive label tape with the frame portion removed.
[0033]
As shown in FIG. 4, the tape cartridge 30b includes a housing 41. The housing 41 has the same configuration as the housing 41 of the laminated thermal transfer type tape cartridge 30a described above. That is, the housing 41 can be used for both types of tape cartridges 30a and 30b, so that the versatility of the housing 41 can be improved, the number of parts can be reduced, and the manufacturing cost can be reduced. .
In the tape cartridge 30b, of the above-described three storage portions P1, P2, and P3, only the first storage portion P1 is wound and stored.
[0034]
In the first accommodating portion P1 of the housing 41, a cylindrical label tape spool 45 is fitted to the third boss portion 53 so as to be freely rotatable.
A thermal label tape 46 is wound around the label tape spool 45. As shown in FIG. 6, the heat-sensitive label tape 46 is bonded to the heat-sensitive paper 47 having a heat-sensitive color forming layer formed on one side and an adhesive applied to the other surface, and the pressure-sensitive adhesive side of the heat-sensitive paper. The release paper 48 has a double structure. The thermal label tape 46 is half-cut (specifically, die-cut) on the thermal paper side, and a plurality of label portions 47a having the same shape can be peeled at equal intervals in the longitudinal direction. It has an arranged configuration. The portion other than the portion where the label portion 47a is formed is a frame portion 47b and is not used as a label.
However, as a configuration of the heat-sensitive label tape, a type in which the frame portion 47b is peeled and removed in advance after die cutting (a type in which so-called residue raising) is applied as shown by reference numeral 46 'in FIG.
The heat-sensitive label tape 46 (or 46 ') having such a configuration is wound on the label tape spool 45 as shown in FIG. 4 so that the label portion 47a is on the inner side.
[0035]
A guide body 56 serving as a protective member is fixed on the inner side (the side facing the first boss portion 51) of the wall portion 55 formed in the second housing portion P2. The guide body 56 has an arcuate surface in which the first boss portion 51 side is convex, and comes into contact with and guides the thermal label tape 46 passing across the second housing portion P2, as will be described later. It is supposed to be.
[0036]
A travel path of the thermal label tape 46 in the cartridge 30b having the above-described configuration will be described with reference to FIG. 5 in a state where the cartridge 30b is attached to the apparatus.
After the thermal label tape 46 is pulled out from the first housing portion P1, the thermal label tape 46 reaches the inside of the second housing portion P2 through the gap provided in the wall portion 55. In the second housing part P2, the thermal label tape 46 is gently bent in its running direction while sliding with the thermal paper 47 side (label part 47a side) in contact with the arc surface of the guide body 56, and finally. Exits the second housing part P <b> 2 from the gap provided in the wall part 55 and heads toward the second boss part 52.
As a result of the provision of the guide body 56 in this manner, the thermal label tape 46 is prevented from directly contacting the wall portion 55. Therefore, even if the wall portion 55 is provided so as to be sharply convex with respect to the travel path of the tape 46, the tape 46 is rubbed against the wall portion 55 when passing through the second storage portion P2 in the cartridge 30b. The label 47a is prevented from being peeled off, and the label 47a can be smoothly supplied to the thermal head 13.
[0037]
Further, the arc surface of the guide body 56 (that is, the surface in contact with the label portion 47a of the thermosensitive label tape 46) is subjected to silicon-based surface treatment. With this configuration, the friction between the guide body 56 and the label portion 47a is reduced, the slip is improved, and peeling of the label portion 47a in the cartridge 30b can be more reliably prevented.
[0038]
The thermal label tape 46 is bent again by contacting the circumferential surface of the second boss portion 52 and is sent between the platen roller 21 and the thermal head 13. Then, by selective heating of the heating element of the thermal head 13 provided so as to face the thermal paper side of the tape 46, desired characters and symbols are thermally colored on the thermal paper 47 side, and printing is performed. Done. The heat-sensitive label tape 46 after printing is further fed by the feed roller 22 and the joining roller 38 and discharged from the discharge port 2b.
[0039]
As shown in FIG. 6 or FIG. 7, black marks M are provided at equal intervals on the release paper 48 side of the thermal label tape 46 (46 ′) by printing, and the intervals between the marks M are as described above. The interval of the label 47a on the thermal paper 47 side is the same. Each mark M has a position to be attached so as to have a specific positional relationship with the individual label portion 47a on the opposite side.
On the other hand, a photo sensor 18 for reading the mark M of the traveling tape 46 is installed on the cartridge mounting frame 11 side. Accordingly, the printing position is aligned by setting the timing at which the mark M is detected by the photosensor 18 and the timing at which the heating element of the thermal head 13 generates heat, and the image formed by the thermal head 13. Is prevented from being removed from the label portion 47a. Note that the photosensor 18 is not used when the above-described laminate type cartridge 30a is mounted.
[0040]
Since no ink ribbon is required for printing on the thermal label tape 46, the ribbon take-up spool 35 is not provided in the cartridge 30b. Therefore, when the cartridge 30b is attached to the cartridge mounting frame 11 for printing, the take-up drive shaft 15 is idled.
[0041]
Instead of providing the above-described guide body 56 as a protective member, a flexible loop-shaped dummy tape 57 may be provided so as to surround the wall portion 55 as shown in FIG. The material of the dummy tape 57 is, for example, a PET film, and the width of the heat-sensitive label tape 46 and the width thereof are substantially equal (or slightly wider than the heat-sensitive label tape 46).
According to this configuration, since the dummy tape 57 is always interposed between the heat-sensitive label tape 46 and the wall portion 55, the heat-sensitive label tape 46 does not directly touch the wall portion 55 and is similar to the above-described FIG. The label portion 47a can be prevented from peeling off.
Further, in this configuration, the dummy tape 57 travels on an endless route so as to be dragged by the traveling thermal label tape 46. That is, unlike the above-described guide body 56, the thermal label tape 46 does not slide on the dummy tape 57, but the dummy tape 57 travels together with the thermal label tape 46. Accordingly, there is an advantage that the rubbing between the dummy tape 57 and the label portion 47a hardly occurs, and the peeling of the label portion 47a can be more reliably prevented.
[0042]
The above-described loop-shaped dummy tape 57 is configured so as to surround only the wall portion 55 as shown in FIG. 8, so that the dummy tape 57 can be configured to be short and the manufacturing cost can be reduced. However, as shown in FIG. 9, a large loop path that passes between the thermal head 13 and the platen roller 21 may be configured.
In FIG. 9, the thermal path of the thermal label tape 46 from the first accommodating portion P <b> 1 to the discharge port 2 b is thermally transferred from the wall portion 55 via the second boss portion 52 and the pin 63. In the portion up to the head 13, the dummy tape 57 travels while contacting the surface on the label portion 47a side. Therefore, it is advantageous in that it is possible to prevent the label portion 47a from being peeled off at the second boss portion 52 and the pin 63 as well as the label portion 47a coming off due to the tape 46 coming into contact with the wall portion 55.
At this time, since the dummy tape 57 is interposed between the thermal head 13 and the thermal label tape 46, the dummy tape 57 is formed thin so as not to prevent thermal coloring of the thermal label tape 46. It is necessary to do.
[0043]
As shown in FIG. 10, the thermal label tape 46 accommodated in the first accommodating portion P1 is wound around the label tape spool 45 by double winding with the dummy tape 57 previously stacked, From the portion P1, the thermal label tape 46 and the dummy tape 57 may be pulled out in an overlapped state.
If the two tapes 46 and 57 are pulled out with the dummy tape 57 positioned on the wall 55 side of the thermal label tape 46, the thermal label tape 46 touches the wall 55 and the label portion 47a. Can be prevented from peeling off. In this configuration, since the label portion 47a is protected by the dummy tape 57 from the beginning when the heat-sensitive label tape 46 is pulled out from the first housing portion P1, the label portion 47a is protected and prevented from peeling off. Can be.
In the configuration shown in FIG. 10, a dummy tape take-up spool 58 is provided in the take-up drive shaft 15, and when the drawn-out dummy tape 57 passes through the second boss portion 52, the dummy tape is provided. A take-up spool 58 is used for winding and collecting.
[0044]
Even in the configuration of this dummy tape double winding, the dummy tape 57 can be configured to pass through the thermal head 13 portion, similarly to the configuration of the loop-shaped dummy tape described above. An example of this configuration is shown in FIG.
In the configuration of FIG. 11, when the dummy tape 57 passes across the second housing portion P2 and is sent from the second boss portion 52 via the pin 63 to the thermal head 13 and passed, the pin 64 To the dummy tape take-up spool 58 to be taken up. With this configuration, it is possible to prevent the label portion 47a from being peeled off not only at the wall portion 55 but also at the second boss portion 52 and the pin 63.
In this case as well, it is desirable to reduce the thickness of the dummy tape 57 in order to prevent a decrease in the thermal coloring sensitivity of the thermal label tape 46 during printing with the thermal head 13, as in the configuration of FIG.
[0045]
Although the embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the configuration of the above embodiment, and various modifications can be made without departing from the spirit of the present invention. is there.
For example, the label tape cartridge 30b of the present embodiment uses a thermal recording type label tape (thermal label tape 46 or 46 '), but is not limited thereto. However, the thermal recording type label tape is colored by rubbing against other members, and there is a strong possibility of causing the quality of the formed image to be deteriorated. Therefore, it can be said that the configuration of the present invention is particularly suitable for a thermal recording type label tape cartridge.
[0046]
