Abstract

PURPOSE:To enable an as-printed state to be kept as it is even though the printed-out are left stand for a long time by a method wherein a roller coming in contact with a heat sensitive color couple layer of thermal coloring paper and a fixing solution supply means for supplying fixing solution to the roller are established. CONSTITUTION:A character and a graphic are printed on a heat sensitive color coupler layer 18 of tag use thermal coloring paper 14 with a thermal head 24. The tag use thermal coloring paper 14 in which the character, the graphic etc. are printed is sent to a device for giving fixing solution 26. In the device for giving fixing solution 26, fixing solution 36 is sucked up by a capillary phenomenon of a fibrous material 34, is stuck to a fixing solution supply roller 32, and further is supplied to a roller for giving fixing solution 28. Then, the fixing solution 36 is given to the heat sensitive color coupler layer 18 of the tag use thermal coloring paper 14 from the roller for giving fixing solution 28. Since heat sensitive color coupler to be used for the heat sensitive color coupler layer 18 is fixed with this fixing solution 36, the prints do not discolor even though a long time has elapsed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a printer, and more particularly to a printer for printing characters, figures, etc. on heat-sensitive coloring paper for tags used as hang tags.

(Prior Art) FIG. 4 is an illustrative diagram showing an example of a conventional printer, which is the background of the present invention. This printer 1 includes a holding roller 2 on which a heat-sensitive coloring paper 3 on which a heat-sensitive coloring agent layer is formed is held in the form of a roll. This thermosensitive coloring paper 3 is wound onto a winding roller 5 via a roller 4.

A thermal head 6 is installed on the transfer path of the thermosensitive coloring paper. The thermal head 6 heats the thermosensitive coloring agent layer of the thermosensitive coloring paper 3, and characters, figures, etc. are printed on the heated portions of the thermosensitive coloring agent layer.

(Problem to be Solved by the Invention) However, in printed matter printed with such a printer, the heat-sensitive coloring agent layer of the heat-sensitive coloring paper changes color as time passes, so it is difficult to maintain the state in which it was printed for a long time. could not.

Therefore, the main object of the present invention is to provide a printer that can maintain the original state of printing on thermal coloring paper for a long period of time.

(Means for Solving the Problems) The present invention includes a holding means for holding a heat-sensitive coloring paper on which a heat-sensitive coloring agent layer is formed, and a transfer means for transporting the heat-sensitive coloring paper held by the holding means. , a heating means provided on the transfer route of the heat-sensitive coloring paper and for coloring the heat-sensitive coloring agent layer by heating the heat-sensitive coloring agent layer; and a heating means provided on the transfer route of the heat-sensitive coloring paper and used for the heat-sensitive coloring material layer. A printer comprising: a fixer applying means for applying a fixer for fixing a heat-sensitive coloring agent; a fixer supply means for supplying a fixer solution;
It's a printer.

(Function) A fixer is applied to the heat-sensitive coloring paper by the fixer-applying means of the printer, thereby fixing the heat-sensitive coloring agent used in the heat-sensitive coloring agent layer.

(Effects of the Invention) According to the present invention, even if a printed matter printed by a printer is left for a long time, it can maintain its original state when printed.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Embodiment) FIG. 1 is an illustrative diagram showing an embodiment of the present invention. This printer IO includes a holding roller 12.

The holding roller 12 holds a roll of thermosensitive coloring paper 14 for tags.

The heat-sensitive coloring paper 14 for tags includes a belt-shaped sheet material 16, as shown in FIG. This sheet material 16 is formed of paper or the like having a thickness of about 150 to 300 μm, for example. A plurality of cuts 17 are formed in the sheet material 16 at intervals and extending in the width direction thereof. This cut 17 is formed, for example, as a perforation. A heat-sensitive coloring agent layer 18 is formed on one main surface of this sheet material 16. The heat-sensitive coloring agent layer 18 develops color when heated, thereby printing characters, figures, etc. on the heat-sensitive coloring agent layer 18. As the heat-sensitive color former used in this heat-sensitive color former layer 18, a fixable heat-sensitive color former is used.

The thermosensitive coloring paper 14 for tags held by the holding roller 12 is pulled out, folded back by the folding roller 20, and wound up by the winding roller 22.

The heat-sensitive coloring paper 14 for tags is sequentially transferred from the holding roller 12 by being wound up by the take-up roller 22 .

A thermal head 24 is installed on the transfer path of the thermosensitive coloring paper 14 for tags. The thermal head 24 heats the thermosensitive coloring agent layer 18 of the thermosensitive coloring paper 14 for tags,
As a result, characters, figures, etc. are printed on the heat-sensitive coloring agent layer 18.

Furthermore, a fixer applying device 26 is installed downstream of the thermal head 24 on the transfer path of the thermosensitive coloring paper 14 for tags. This fixer applying device 26 includes a fixer applying roller 28.
including. This fixer applying roller 28 contacts the heat-sensitive coloring agent layer 18 side of the heat-sensitive coloring paper 14 for tags, and further roller 3
0, the heat-sensitive coloring paper 14 for tags is attached to the fixer application roller 2.
Pushed to 8. Further, the fixer fluid application device 26 includes a fixer fluid supply roller 32 that contacts the fixer fluid application roller 28 . One end of a fibrous material 34 such as felt is brought into contact with the fixer supply roller 32 . Then, the other end of this fiber material 34 is immersed in an amine-based fixer 36. By applying this fixer 36, the heat-sensitive color former used in the heat-sensitive color former layer 18 is fixed.

In this printer 10, characters, figures, etc. are printed by the thermal head 24 on the heat-sensitive coloring agent layer 18 of the heat-sensitive coloring paper 14 for tags. Then, the thermosensitive coloring paper 14 for tags on which characters, figures, etc. are printed is sent to the fixer application device 26. In this fixer applying device 26, the fixer 36 is sucked up by the capillary action of the fibrous material 34. The sucked up fixer fluid 36 adheres to the fixer fluid supply roller 32, and is further transferred from the fixer fluid supply roller 32 to the fixer fluid application roller 2.
8. Then, the fixer 36 is applied from the fixer applying roller 28 to the heat-sensitive coloring agent layer 18 of the heat-sensitive coloring paper 14 for tags.

The heat-sensitive coloring agent used in the heat-sensitive coloring agent layer 18 is fixed by this fixing liquid 36. Therefore, this printer 1
Printed matter printed using 0 does not change color even after a long period of time, and can maintain its original state when printed.

This heat-sensitive coloring paper 14 for tags has a cut 17 in the sheet material 16.
By cutting it off at the forming part and attaching a thread 40 or the like as shown in FIG. 3, it can be used as a tag such as a hang tag.

The tags obtained in this way do not fade or change color even after a long period of time, and can maintain their original state when printed.
