Abstract

The utility model relates to the technical field of the stationary and office supplies, in particular to a device for displaying invisible printed ink, principally comprising a box body, whose upper end face is provided with a light-passing board, and an ultraviolet, infrared or far infrared luminary is arranged in the box body. When using the utility model, a paper printed or wrote by invisible printing ink is placed on the light-passing board of the box body, with turning on a switch, the light source in the box body is transmitted through the back of the paper, and the user can clearly see the words or patterns in the paper printed or wrote by invisible printing ink. By using the utility model, when the user observes the paper printed or wrote by invisible printing ink, the full sheet of the paper can be completely seen only once, so the device for displaying invisible printed ink is convenience compared with the light emission pen or electrical flashlight at present.

Description

Be used for the device that invisible printing ink is shown one's color

Technical field:

The utility model relates to the stationery field, refers in particular to a kind of device that special invisible printing ink can be shown one's color.

Background technology:

Learn in employed training book or the workbook, it all is blank needing among the exercise to fill a vacancy or will providing result's part, need to fill in the top after practitioner oneself thinking, usually the answer that can whole enclose all exercises at the last few pages of training book, like this, when we finish the exercise after just can proofread and correct according to the answer of back whether correct.But when exercise is more, adopts and proofread and correct answer in such a way, can delay a lot of time unavoidably, and page stirs before and after needing constantly, also misunderstand answer because of dim eyesight easily.

Along with science and technology development, invent out a kind of invisible printing ink now, adopt the literal of this ink printing or pattern under normal conditions human eye can't see that this is because include at least a metal phthalocyanine dye fluorescence group in this invisible printing ink; This fluorophore can absorb ultraviolet ray, infrared ray or far infrared, exhales the visible light of wavelength in certain limit then, and promptly this printing ink has only by just seeing behind ultraviolet ray, infrared ray or the far-infrared radiation.This printing ink is usually used in the false proof table knowledge.As see a kind of printing ink described in German patent DE 3529798 patent specifications, its fluorescent material by alcoholic solvent, water soluble/alcohol mixture, water miscible polyacrylate and dispensable water-soluble cellulose and diethanolamine are formed.There has been the people that this kind printing ink is used for people's workbook used in everyday or training book at present.Answer is adopted the invisible printing ink printing or is write in this workbook or the training book, is to see under normal conditions, and the user can only see the exercise that employing is generally shown one's color ink printing or write.Then, the user can fill in answer in the blank position corresponding with exercise with pen.After exercise is all finished, the user is shone the blank position place of above-mentioned fill out answers by the light pen (or torch) that can send ultraviolet ray, infrared ray or far infrared, the answer of so prior employing invisible printing ink printing just displays, the exercise that the user is done with regard to recoverable oneself.But because the limitation of light pen (or torch) light source of this check and correction answer, the scope of its each irradiation is very limited, can't one time the answer of exercise in the preview full page, need constantly to adjust the zone of light-illuminating, proofread the answer of each exercise respectively, and in use need frequent irradiation, operate comparatively loaded down with trivial details.

Summary of the invention:

The purpose of this utility model is, by utilization with improve prior art, provides a kind of device that invisible printing ink is shown one's color that is used for easy to use, simple in structure.

In order to achieve the above object, the utility model is achieved through the following technical solutions: this device mainly comprises a box body, and what installed the box body upper surface is a light-passing board, and a ultraviolet ray or infrared ray or far infrared luminophor are installed in box body.

Described luminophor is positioned at the middle part of box body hollow cavity.

Perhaps described luminophor is positioned at a side of light-passing board, and its direction of illumination points to another side of light-passing board on the other side.

When using the utility model, the paper that employing is had the invisible printing ink printing or write is placed on the light-passing board of box body, open switch, the light source in the box body will be transmitted by back side of paper, and the user can clearly see employing invisible printing ink printing or literal of writing or pattern in the paper.After using the utility model, the user checks and when printing of this employing invisible printing ink or the paper write, once just can full size is existing fully, and it is convenient, quick to adopt light pen or torch relatively at present.

Embodiment:

See Fig. 1,2, the utility model mainly comprises a box body 1, and this box body 1 upper surface is equipped with light-passing board 2, and a ultraviolet ray or infrared ray or far infrared luminophor 3 are installed in box body 1.Common infrared lamp, UV-lamp that described luminophor 3 can adopt present market to sell, this luminophor 3 is positioned at the middle part of box body 1 hollow cavity.Box body 1 is provided with the switch 4 of a control luminophor 3, and whether switch 4 control luminophors 3 are luminous with power turn-on.

See Fig. 3, when using the utility model, the paper 5 that employing is had the invisible printing ink printing or write is placed on the light-passing board 2 of box body 1, open switch 4, the light source of luminophor 3 will be transmitted by paper 5 back sides in the box body 1, and the user can clearly see employing invisible printing ink printing or literal of writing or pattern in the paper 5.After using the utility model, the user checks and this employing has the invisible printing ink printing or during the paper write, once just full size can be manifested fully that it is convenient to adopt light pen or torch relatively at present.

See Fig. 4,5, in the present embodiment, luminophor 3 also can be positioned at a side of light-passing board 2, and its direction of illumination points to another side of light-passing board 2 on the other side.The use-pattern of present embodiment is same as described above, is not giving unnecessary details one by one here.

See accompanying drawing 6, use for the ease of the user, one rotating paper roll 60 is installed in box body 1 in the present embodiment, being about to paper roll 60 is set in the box body 1 one 61, the hole slot of being offered by box body 1 upper surface around an end of the paper of rolling up 6 on the paper roll 60 11 passes, and can be constantly by pulling out in the box body 1 under user's pullling.In use, print or write the literal or the character of employing invisible printing ink on the paper 6 in the paper roll 60, be example with the English learning in the present embodiment, on paper 6, be printed with stealthy " A ", " B ", " C ", " D ", " E ", " F " ... the user opens the luminophor 3 in the box body 1 earlier, letter on the paper 6 is manifested, begin then to describe along the letter that provides, after having described, luminophor 3 is closed, just can see letter that oneself has just been described, so just can be familiar with the literary style of English alphabet.Learning to write by tracing over characters printed in red in the similar calligraphy of this mode, different is that it is to see as the reference letter of writing under normal conditions, can know after having copied like this and see the deficiency of oneself writing, to improve study schedule as early as possible.

The above only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
