[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sheet in which a large number of labels are continuously attached on the surface of a long sheet of paper, and a label printer for printing an image on the label of such a label sheet. .

[0002]

2. Description of the Related Art A first conventional example of a label sheet will be described with reference to FIG. First, the label sheet 1 has a structure in which a large number of rectangular labels 3 are continuously attached on the surface of one long sheet 2, and the long sheet 2 is peeled off on the surface of the backing sheet 4. It has a structure in which the release surface 6 is formed by laminating the agents 5. Then, the label 3 forms an adhesive surface 9 by laminating an adhesive 8 on the back surface of a label base 7,
A heat sensitive layer 10 and an overcoat layer 11 are sequentially laminated on the surface of the label base 7 to form a printed surface 12.

In a label printer (not shown) using such a label sheet 1, for example, a sheet transport mechanism for sequentially transporting the label sheet 1 is formed by a platen roller or the like, and the label 3 of the label sheet 1 An image printing mechanism for performing image printing is formed by a thermal head or the like disposed opposite to the sheet transport mechanism, and a label issuing unit for issuing the label 3 of the label sheet 1 is formed by a peeling member or the like that bends the long sheet 2 at a sharp angle. It has a structured structure.

In such a configuration, in the above-described label printer, when the label sheet 1 is sequentially conveyed by the sheet conveying mechanism, the printing surface 12 of the label 3 is printed by the image printing mechanism.
The lower heat-sensitive layer 10 is selectively heated, and the heat-sensitive layer 10 is partially colored to print an image on the printing surface 12 of the label 3. Then, the long sheet 2 of the label sheet 1 is sequentially conveyed by the sheet conveying mechanism, bent sharply by the peeling member, and the first half of the label 3 is peeled from the long sheet 2 on the peeling member.

[0005] In the above-described manner, a label 3 on which a desired image is printed can be issued.
The label 3 can be attached to a product (not shown) as a price tag. Here, at present, label sheet 1
It is also practiced to print the address on the label 3 and affix it to a mail (not shown). In such a case, a receipt (not shown) describing the same contents as the label 3 is used. Must be issued to the customer (not shown).

Therefore, a label sheet which addresses such a problem will be described as a second conventional example with reference to FIG.
Here, the same portions as those of the label sheet 1 described above as the first conventional example are denoted by the same names and reference numerals, and detailed description is omitted. First, the label sheet 13 has a structure in which a large number of rectangular labels 3 are continuously attached on the surface of one long sheet of paper 14. The structure of the label 3 is similar to that of the label sheet 1 described above. Has become. The long sheet 14 of the label sheet 13 forms a release surface 6 by laminating a release agent 5 on the surface of the mount 4, and forms a heat-sensitive layer 15 and an overcoat layer 16 on the back of the mount 4. The printing surface 17 is formed by sequentially laminating the printed surface 17.

A conventional example of a label printer using such a label sheet 13 will be described with reference to FIG. First, in the label printer 18, a sheet transport mechanism for sequentially transporting the label sheet 13 and the long paper 14 is formed by two platen rollers 19, 20 and a discharge roller 21, and the surface of the label 3 of the label sheet 13 and the sheet transport mechanism are formed. An image printing mechanism for printing an image on the back surface of the long paper 14 is formed by the thermal heads 22 and 23 opposed to the platen rollers 19 and 20, and the label issuing means for issuing the label 3 of the label sheet 13 is provided by the length. The length paper 14 has a structure formed by a peeling member 24 that bends at a sharp angle. In the label printer 18, since images are printed on both the front and back surfaces of the label sheet 13, the platen rollers 19 and 20 and the thermal heads 22 and
23 is upside down.

In such a configuration, in the label printer 18, when the label sheet 13 is sequentially conveyed by rotating platen rollers 19 and 20, the thermal head 2 is used.
An image is printed on the printing surfaces 12 and 17 of the label 3 and the long paper 14 by the heating scans 2 and 23. Therefore, the rollers 19 to 21 that rotate the long sheet 14 of the label sheet 13 are used.
And the paper is sequentially bent at a sharp angle by the peeling member 24, and the first half of the label 3 is peeled from the long paper 14 on the peeling member 24.

By doing so, the label printer 18 can issue both the label 3 on which the desired image is printed and the long paper 14. (Not shown), and a long sheet 14 printed with the same contents as the label 3 can be issued to a customer (not shown) as a receipt.

[0010]

In the above-described label printer 18, the label 3 of the label sheet 13 and the long sheet 1 are used.
4 can be printed.

However, the label printer 18 requires both the platen rollers 19 and 20 and the thermal heads 22 and 23 to print images on the front and back surfaces of the label sheet 13, respectively. Productivity improvement is hindered.

For example, Japanese Patent Application No. 4-330527 discloses a printer device that prints an image with a single print head on a recording medium having a print surface on both sides, such as the label sheet 13 described above. And the like. However, this printer device has a structure in which cut-sheet paper on which an image is printed on the front surface by a print head is returned under the print head in a U-shaped paper conveyance path, and can inevitably handle only cut-sheet paper. So label sheet 1 as described above
3 is not available.

In order to print an image on both the label 3 of the label sheet 13 and the long paper 14 having the above-described structure, the platen rollers 19 and 20 and the thermal heads 22 and 23 need to be provided.

The RAM 54 includes a reception buffer for temporarily storing the received character code, an image buffer for temporarily storing bit image data developed from the character code, and various transport counters for setting the number of steps of the stepping motor 55. Is formed in advance.

In the label printer 34, a sheet transport mechanism for transporting the label sheet 25 in the forward and reverse directions is formed by the platen roller 40, the stepping motor 55, and the like. An image printing mechanism for printing images on the printing surfaces 12 and 32 of the label sheet 25 is formed by the thermal head 39 and the like.

Further, in the label printer 34, the CPU 52 drives and controls the above-described sheet conveying mechanism and the image printing mechanism in accordance with the data stored in the ROM 53 and the RAM 54, thereby conveying the label sheet 25 in the forward direction. A label printing means for printing an image on the printing surface 12 of the label 27 by means of the label printing means; A label issuing unit that issues the label 27, a sheet reverse feeding unit that transports the long sheet 26 from which the label 27 has been peeled off in a reverse direction to a predetermined position, and then transports the long sheet 26 in a forward direction. Sheet printing means for printing an image on the printing surface 32 of the long sheet 26 conveyed by the reverse feeding means is realized. .

In such a configuration, the label printer 34 includes an inner-wound label sheet 25 as illustrated in FIG. 3A and an outer-wound label sheet 25 as illustrated in FIG. It is possible to correspond to both. Further, in the label printer 34, when maintenance work such as replacement of the label sheet 25 or jam clearance is performed, as illustrated in FIG. 4, the upper housing 42 and the thermal head 39 are swung upward to feed the sheet. Part 37
And the image printing section 36 are exposed, and the label sheet 25 on the sheet supply section 37 is exposed to the image printing section 36.
, The label sheet 25 is manually inserted between the sheet guides 44 and positioned on the platen roller 40. In the label printer 34, it is necessary to stop the operation of the image printing section 36 and the like in the state where the thermal head 39 is rotated upward. The power supply to each unit is controlled by detecting the presence or absence of the opening and closing of 39.

Various operations in the case where the label printer 34 prints an image on the label 27 of the label sheet 25 and the long paper 26 will be described with reference to FIGS. 6 and 7. FIG. First, in the label printer 34, the label sheet 25 is set from the sheet supply section 37 to the image printing section 36 with the upper housing 42 and the thermal head 39 opened upward as described above, and then the thermal head 39 and the upper When the housing 42 is closed, the CPU detects the closing with a lock sensor (not shown), an optical sensor 51, or the like.
A label 52 conveys the label sheet 25 by rotating the platen roller 40 based on the detection output of the optical sensor 43 and
The front edge of the print head 7 is positioned below the thermal head 39, and this is set as an initial state to wait for a printing operation.

Therefore, the communication I / F 5 in the state described above
When print information is received from a host computer (not shown) or the like connected to
52 temporarily stores the print information in the reception buffer of the RAM 54, develops the character code of the print information into bit image data in accordance with the C / G of the ROM 53, temporarily stores this in the image buffer of the RAM 54, And the driving of the stepping motor 55 is started.

Therefore, the CPU of the label printer 34
52, a one-line image is printed on the printing surface 12 of the label 27 of the label sheet 25 by the thermal scanning of the thermal head 39, and then the label sheet 25 is rotated by one line by the rotation of the platen roller 40 by the stepping motor 55. , And the printing operation is sequentially repeated until the optical sensor 51 detects the leading edge of the label 27. And
When the CPU 52 detects the leading edge of the label 27 on which the image information is sequentially printed by the optical sensor 51, the CPU 52 sets a numerical value corresponding to the front and rear length of the label 27 in the RAM 54 as a label positive transport counter, After this setting, the thermal head 39 and the stepping motor 55
Each time the printing operation of one line is repeated, "1" is subtracted from the label normal transport counter.

Then, when the CPU 52, which has detected that the label normal transport counter has become "0", stops the rotation of the stepping motor 55, as shown in FIG. Since the first half of the completed label 27 is peeled off from the long sheet 26 bent sharply by the peeling member 45 and protrudes from the optical sensor 51 to the outside of the main body housing 35, the example is shown in FIG. As described above, the user (not shown) manually peels off the label 27 issued by the label printer 34 from the long paper 26 as described above. At this time, the long paper 26
The issued label 27 protruding forward from above is detected by the optical sensor 51, and when the issued label 27 is manually separated from the long sheet 26 and taken out, the optical sensor 5
The detection output of No. 1 stops.

When the CPU 52 detects the completion of the issuance of the label 27 due to the stop of the detection output of the optical sensor 51, the CPU 52 sets a numerical value corresponding to the front and rear length of the label 27 in the RAM 54 as a sheet reverse conveyance counter, and performs stepping. Platen roller 40 by motor 55
Is rotated in the reverse direction to convey the label sheet 25 by one line in the reverse direction, and every time such a conveyance operation is repeated, "1" is subtracted from the sheet reverse conveyance counter. And
When the CPU 52 detects that the sheet reverse conveyance counter has become “0” and stops the rotation of the stepping motor 55, in this state, as shown in FIG. The front edge of the printing surface 32 is located below the thermal head 39.

When the CPU 52 detects the completion of the reverse transport of the long sheet 26 as described above, the CPU 5
Numeral 2 sets a numerical value corresponding to the front and rear length of the printing surface 32 of the long paper 26 in the RAM 54 as a sheet normal conveyance counter,
After this setting, the thermal head 39 and the stepping motor 55 are driven to decrement "1" from the sheet normal conveyance counter every time a predetermined image is printed line by line on the printing surface 32 of the long sheet 26.

When the CPU 52 detects that the sheet normal conveyance counter has become "0" and stops the rotation of the stepping motor 55, the image printing is stopped in this state as illustrated in FIG. Since the end of the completed long sheet 26 projects outside the main body housing 35 from below the sheet cutter 48, the user can use the label printer 3 as described above as illustrated in FIG.
4 is a sheet cutter 48.
Will be cut off.

By doing so, the label printer 34 can issue both the label 27 on which the desired image is printed and the long paper 26. For example, the label 27 on which the address is printed is (Not shown) and printed on the long paper 26 having the same content as the label 27 printed thereon.
Can be issued to a customer (not shown) as a receipt. In addition, since the label printer 34 prints an image on both the label 27 of the label sheet 25 and the long sheet 26 with one thermal head 39 as described above, the structure is simple and compact. This can contribute to weight reduction and productivity improvement.

That is, in the label sheet 25 of the present invention,
When the label 27 on which the image printing is completed is peeled off from the printing surface 12, the image printing can be executed on the printing surface 32 of the long paper 26, and the printing surface 12, which is located on the surface of the label 27 and the long paper 26. 32 can be treated equally,
As described above, the thermal head 39 can execute image printing on both the label 27 and the long sheet 26 with one label printer 34.

In the label printer 34 of this embodiment, the long paper 26 on which the image printing is completed is transferred to the sheet cutter 4.
Although it was illustrated that the receipt was cut at step 8 in the present embodiment, the present invention is not limited to the above-described embodiment. For example, a label on which image printing has been completed is attached as a receipt to a shopping bag (not shown). However, it is also possible to store a long sheet on which image printing has been completed as a journal.

In the label sheet 25 of this embodiment,
An annular adhesive surface 29 is formed on the outer peripheral portion of the back surface of the rectangular label 27, and a peeling surface 33 is formed in a ladder shape on the surface of the long paper 26 so that the rectangular printing surfaces 32 are continuously scattered. Although the present invention is not limited to the above embodiment, for example, an adhesive surface is formed on both sides of the back surface of a rectangular label, and a peeling surface and a printing surface that are continuous in the longitudinal direction are long. It is also feasible to form them on both sides and the center of the sheet surface.

Further, here, the heat-sensitive printing surfaces 12, 32 are formed on the label 27 of the label sheet 25 and the long sheet 26, and the image printing mechanism of the label printer 34 is formed by the thermal head 39 or the like.
