Description

  The present invention relates to a partially labeled roll paper having improved printing characteristics by a printer.

  In recent years, there has been an increasing demand for forms that can be printed using a handy terminal type printer such as a parking violation display label and that can be pasted after printing. As such a form, a label sheet devised by the present applicant is well known (see Patent Document 1 below).

  The label sheet of this document has a printing unit on the front surface of the paper, and a release paper is bonded on the adhesive partially applied to the back surface of the paper. Further, the release paper is strongly adhered at the leading end and weakly adhered at the trailing end, and is configured to be able to be folded between the two. In use, only the rear end portion of the release paper is peeled off and folded outward, and the exposed weak adhesive portion is attached to the adherend. By adopting a structure in which the release paper is not peeled off in this way, dust is not generated at the time of use, and its utility value is high.

Utility Model Registration No. 3112047

  By the way, as represented by the above-described label sheet, in a so-called partial label sheet in which a release paper is partially bonded to the back surface of the paper, there is a problem in transportability and printability during printing. That is, the partial label sheet has a structure in which a step is generated between a portion where the release paper is bonded and a portion where the release paper is not bonded. For this reason, when a partial label sheet is printed by a printer, this level difference becomes a resistance to the platen roller, which may cause a conveyance trouble such as a paper jam or misfeed. In addition, due to this step, the print head does not move smoothly at the boundary portion of the release paper, and there is a problem that printing defects such as missing prints and blurred characters occur.

  Therefore, the present invention has been made to solve such a problem, and in a roll paper with a partial label that can be printed by a handy terminal type printer, it prevents a printing trouble and a printing defect to improve printing characteristics. The purpose is to let you.

  In order to achieve the above object, the partially labeled roll paper of the present invention is designed to reduce the resistance of the release paper to the platen roller during printing.

  That is, the roll paper with a partial label according to the first embodiment of the present invention is a pressure-sensitive adhesive that is provided with a printing portion on the surface of a long sheet-like base material and is partially applied to the back surface of the base material. About the partial label sheet | seat on which the release paper was bonded together so that peeling | exfoliation paper was peeled, the paper thickness of the said release paper shall be 65 micrometers or less, and the said partial label sheet is wound in roll shape, It is characterized by the above-mentioned.

  In addition, the partially labeled roll paper according to the second embodiment of the present invention is a pressure-sensitive adhesive that is provided with a printing unit on the surface of a long sheet-like substrate and is partially applied to the back surface of the substrate. About the partial label sheet on which the release paper is detachably bonded, the release paper is calendered, and the partial label sheet is wound into a roll shape.

  In addition, the partially labeled roll paper according to the third embodiment of the present invention is a pressure-sensitive adhesive that is provided with a printing unit on the surface of a long sheet-like base material and is partially applied to the back surface of the base material. About the partial label sheet on which the release paper is releasably bonded, a sticker having a paper thickness thinner than the release paper is attached to the back surface of the base material adjacent to the longitudinal direction of the release paper, and the partial label The sheet is wound in a roll shape so that the sticker is disposed on the front side in the feeding direction.

  Furthermore, the roll paper with a partial label according to the fourth embodiment of the present invention is a pressure-sensitive adhesive which is provided with a printing unit on the surface of a long sheet-like base material and is partially applied to the back surface of the base material. About the partial label sheet on which the release paper is detachably bonded, one side in the width direction of the release paper is formed in a non-straight line, and the non-linear line is placed on the front side in the feeding direction of the partial label sheet. It is characterized by being wound into a roll so as to be arranged.

  Here, in particular, in the roll paper with a partial label according to the fourth embodiment, the non-linear one side is formed in a V shape with the protruding end facing the front side in the feeding direction, or a concave portion and a convex portion. It is possible to adopt a configuration in which the lines are formed in a wavy line shape that is alternately continuous.

  Moreover, in the roll paper with a partial label according to all the embodiments, it is possible to adopt a configuration in which the printing unit is a thermosensitive coloring layer.

  As apparent from the above-described configuration, according to the roll paper with a partial label of the present invention, the resistance to the platen roller of the release paper bonded to the back surface of the sheet becomes extremely small during printing with the printer, and the paper is abrupt during conveyance. No load is applied. For this reason, it is possible to avoid problems such as paper jams and misfeeds, and to prevent printing defects such as missing prints and blurred characters at the boundary of the release paper. Therefore, there is an effect that printing characteristics by the printer are improved.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

(1) First Embodiment FIG. 1 is an external view of a partially labeled roll paper of the first embodiment viewed from the front side, FIG. 2 is an external view of the partially labeled roll paper viewed from the back side, and FIG. FIG. 4 is an explanatory view showing a state during printing with a thermal printer. In addition, in order to make the structure easy to understand in the drawings, a state in which a predetermined amount of roll paper with partial labels is drawn out is illustrated.

  As shown in FIG. 1, the partially labeled roll paper 10-1 of this embodiment is applied to a parking violation display label. The parking violation display label described below is merely an example of the application of the present invention, and the present invention is not limited to this and can be applied in various situations where the label is attached to the adherend.

  The illustrated display label is produced by using a long sheet-like thermal paper (hereinafter referred to as “thermal sheet”) in the present embodiment, and is partially formed on the back surface of the thermal sheet 20 as shown in FIGS. It is a partial label sheet provided with a label 30. In the longitudinal direction of the partial label sheet, a plurality of perforations 23, 23,... For cutting are formed at predetermined intervals, and a plurality of display labels are connected through the perforations 23 so as to be separable. The partial label sheet is wound in a roll shape so that it can be set in the handy terminal type thermal printer 50.

  The partial label sheet includes a sheet 21 as a base material and a printing unit 22 made of a heat-sensitive color developing layer provided on the surface of the sheet 21. The printing unit 22 includes a character display 22a such as “parking violation vehicle confirmation mark”, “parking violation”, “move quickly”, a parking violation mark 22b, a vehicle information entry column 22c, and a copy entry column. 22d is printed in advance. In the vehicle information entry column 22c, information on the vehicle such as the number of the violating vehicle and the control time is printed using the thermal printer 50, and is used to identify the violating vehicle. The same information is printed in the record entry field 22d, and a police officer who cracks down on the offending vehicle cuts out the perforation 24 after printing and stores it as a record.

  Further, the partial label sheet is provided with a partial label 30 on the back surface of the thermal sheet 20 so that the display label can be attached to the violating vehicle. As shown in FIGS. 2 and 3, the partial label 30 includes an adhesive 32 partially applied to the back surface of the paper 21, and a release paper 31 detachably bonded onto the adhesive 32. . The pressure-sensitive adhesive 32 can be appropriately selected from a permanent adhesion type, a re-peeling type, and a re-peeling / re-sticking type according to the use of the label. In this embodiment, the adhesive is a re-peeling type adhesive, and the adhesive strength thereof should be at least as long as the release paper 31 is not peeled off from the paper 21 at the time of printing and is not easily peeled off after being attached to the vehicle at the time of use.

  As shown in FIG. 4, when the partially labeled roll paper having the above configuration is set in the thermal printer 50 and printing is performed, the partial label sheet fed out from the roll is placed between the thermal head 51 and the platen roller 52. Conveyed continuously. At the time of printing, printing is performed on the surface side of the partial label sheet by heating the printing unit 22 made of the thermosensitive coloring layer with the thermal head 51. At this time, since there is an intermittent step along the longitudinal direction between the paper 21 and the release paper 31 on the back side of the partial label sheet, the resistance when the release paper 31 contacts the platen roller 52 is reduced. If it is large, it is conceivable that the transportability of the sheet and the printability to the printing unit 22 are hindered.

Therefore, in the partially labeled roll paper 10-1 of the present embodiment, means for reducing the resistance of the release paper 31 to the platen roller 52 is provided so that smooth transportability and good printability can be realized. It is a feature. An example of the resistance reducing means, in the present embodiment the sheet thickness T ₁ of the release paper 31 as shown in FIG. 3 is adopted a configuration in which more than 65 .mu.m. This figure is based on the following experimental results.

  The paper thickness of the release paper was changed, and the transportability and printability with a thermal printer were tested. The specifications of the thermal printer model, paper, and release paper used in the experiment are as follows.

Model: Portable mobile thermal printer Paper: Paper width 100 mm, Paper length 8 inches and 10 inches, Roll diameter 50 mm or less (In the paper of FIG. 1, the paper width is W ₁ , the paper length is L ₁ , and the roll diameter is R ₁ . )
Release paper: paper width of 100 mm, paper length of 1.5 inches and 5 inches (in the release paper of FIG. 2, the paper width is indicated by W ₂ and the paper length is indicated by L ₂ ).

Moreover, the release paper used for comparison and each evaluation are as shown in Table 1. Incidentally, the paper thickness of the release paper is shown by W ₁ in FIG.

  As shown in Table 1, when using high-quality paper of 45kg and a paper thickness of 67μm as release paper, there are paper transport problems such as paper jams and misfeeds when printing with a thermal printer, missing prints, blurred characters, etc. Printing failure occurred and good printing could not be performed.

  On the other hand, when a release paper having a copy paper of 43 kg and a paper thickness of 60 μm was used, printing could be performed without any particular problem. Further, when 34 kg of copy paper having a paper thickness of 50 μm was used, very good results were obtained in both transportability and printability. This is considered to be because the resistance at the time of contact with the platen roller decreases as the paper thickness of the release paper decreases.

  Referring to the above experimental results, it was found that if the thickness of the release paper is at least 65 μm or less, printability with a thermal printer can be obtained.

(2) Second Embodiment FIG. 5 is a cross-sectional view showing a partially labeled roll paper according to a second embodiment. In the present embodiment, the same reference numerals are assigned to configurations common to the first embodiment, and detailed description thereof is omitted. In order to facilitate understanding of the structure in the drawing, a state in which a roll paper with a partial label is fed out by a predetermined amount is illustrated, and the portion wound in a roll shape is omitted for convenience of paper. It is.

  The roll paper 10-2 with partial label according to the present embodiment is characterized in that a configuration in which the release paper 31 is calendered as means for reducing the resistance of the release paper 31 to the platen roller 52 is employed.

  That is, as shown in FIG. 5, the adhesive 32 is applied to the back surface of the paper 21, the release paper 31 is bonded, and the partial label sheet is mirror-finished by the calendar processing machine 60. , 61. And the partial label sheet pinched | interposed between the calendar rolls 61 and 61 was strongly pressed, and it wound in roll shape after that.

  Thus, according to the roll paper 10-2 with a partial label of the present embodiment, the release paper 31 that has been subjected to calendering is subjected to the strong pressure of the roller to impart smoothness to the surface, and the paper 21 The level difference with the release paper 31 is reduced and almost eliminated.

  Accordingly, the resistance of the release paper 31 to the platen roller 52 can be extremely reduced during printing with the thermal printer 50, and conveyance troubles such as paper jams and misfeeds can be avoided. Also, printing defects such as missing prints and blurred characters at the boundary of the release paper 31 can be prevented, and the printing characteristics of the thermal printer 50 are improved.

(3) Third Embodiment FIG. 6 is a cross-sectional view showing a partially labeled roll paper according to a third embodiment. Also in the present embodiment, the same reference numerals are assigned to configurations common to the first embodiment, and detailed description thereof is omitted. In order to facilitate understanding of the structure in the drawing, a state in which a roll paper with a partial label is fed out by a predetermined amount is illustrated, and the portion wound in a roll shape is omitted for convenience of paper. It is.

  The partially labeled roll paper 10-3 according to the present embodiment is characterized in that a configuration for reducing the step between the paper 21 and the release paper 31 is adopted as means for reducing the resistance of the release paper 31 to the platen roller 52. It is.

That is, as shown in FIG. 6, a sticker 41 having a paper thickness smaller than that of the release paper 31 is attached to the back surface of the paper 21 with an adhesive 42. The adhering paper 41 is provided adjacent to the longitudinal direction of the individual release papers 31, 31,..., And the partial label sheet is rolled so that the adhering paper 41 is arranged on the front side in the feeding direction indicated by the arrow A in the figure. It is wound in a shape. The feeding direction A is the same as the conveying direction in the thermal printer 50. Incidentally, the release paper 31 can use a sheet thickness _{T 3} is equal to or less than 130 .mu.m, the sheet thickness _{T 3} of a poster 41 is preferably at its thinner even 65μm or less.

  Thus, according to the roll paper 10-3 with partial label of this embodiment, since the sticker 41 is stuck on the back surface of the paper 21, the steep step generated between the paper 21 and the release paper 31 is alleviated. Is done. Further, since the sticker 41 is stuck at the front position of the release paper 31, the thin sticker 41 contacts the platen roller 52 before the release paper 31.

  Accordingly, the resistance of the release paper 31 to the platen roller 52 can be extremely reduced during printing with the thermal printer 50, and conveyance troubles such as paper jams and misfeeds can be avoided. Also, printing defects such as missing prints and blurred characters at the boundary of the release paper 31 can be prevented, and the printing characteristics of the thermal printer 50 are improved.

(4) Fourth Embodiment FIG. 7 is an external view showing a partially labeled roll paper of the fourth embodiment, and FIG. 8 is an external view showing a modification of the partially labeled roll paper. Also in the present embodiment, the same reference numerals are assigned to configurations common to the first embodiment, and detailed description thereof is omitted. In addition, in order to make the structure easy to understand in the drawings, a state in which the roll paper with partial labels is fed out by a predetermined amount is shown.

  The partially labeled roll paper 10-4 according to the present embodiment is configured to prevent the cross section of the release paper 31 from coming into linear contact with the platen roller 52 as means for reducing the resistance of the release paper 31 to the platen roller 52. It is the feature that adopted.

  That is, one side in the width direction of the release paper 31 is formed in a non-linear shape, and this partial label sheet is arranged so that one non-linear side in the release paper 31 is disposed on the front side in the feeding direction indicated by the arrow A in the figure. It is wound in a roll shape. The feeding direction A is the same as the conveying direction in the thermal printer 50.

  As the shape of the release paper 31, for example, as shown in FIG. 7, one non-linear side can be a V-shaped side 31 a. The V-shaped side 31a is formed so that the V-shaped protruding end faces the front side in the feeding direction A. Further, instead of this, as shown in FIG. 8, one side of the non-linear shape may be a wavy side 31b. The wavy side 31b is formed so that concave portions and convex portions are alternately continued. In the drawings, examples of the V shape and the wavy shape are given. However, the shape is not limited to this, and other shapes may be adopted as long as the cross section of the release paper 31 does not contact the platen roller 52 linearly. Is possible.

  As described above, according to the partially labeled roll paper 10-4 of the present embodiment, the one side on the front side in the feeding direction A of the release paper 31 is formed in a non-linear shape. There is no contact with a wide width at the first contact. That is, in the example shown in FIG. 7, only the protruding portion of the V-shaped side 31a is the first contact portion, and in the example shown in FIG. 8, only the convex portion of the wavy side 31b is the first contact portion. The contact width with the platen roller 52 is narrower than that in which one side of the release paper 31 is formed in a straight line.

  Accordingly, the resistance of the release paper 31 to the platen roller 52 can be extremely reduced during printing with the thermal printer 50, and conveyance troubles such as paper jams and misfeeds can be avoided. Also, printing defects such as missing prints and blurred characters at the boundary of the release paper 31 can be prevented, and the printing characteristics of the thermal printer 50 are improved.

  The following modifications can be considered for the embodiment described above. For example, in the production of the partial label sheet, paper 21, that is, a paper medium, was used as the base material. However, if printing is possible on the front side and adhesive 32 can be applied on the back side, the base material is paper. For example, a film medium may be used. The printing method is not limited to the thermal printing method, and other printing methods can be adopted.

  Further, the perforation 23 for cutting is formed on the partial label sheet so that it can be separated into individual label units. However, the perforation 23 is not always necessary, and is, for example, a cutter (not shown) included in the thermal printer 50. You may make it cut out.
