DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruler, and more particularly, to a ruler such as a template capable of forming a fine gap formed between a plate main body and a paper surface by a printed layer.

[0002]

2. Description of the Related Art Heretofore, a template having a perforated portion formed on a resin plate corresponding to various characters, symbols or figures has been used as a drawing article. In this type of template, a gap is formed between the plate body and the paper surface to prevent ink from bleeding.

FIGS. 5 to 7 show partial cross-sectional views of a conventional template in which the gap is formed. In the template 30 shown in FIG. 5, a cutting portion 33 is formed on the lower surface side of the perforated portion 32 formed in the plate main body 31, thereby forming the back surface side forming edge 3 of the perforated portion 32.
2A is provided so as not to directly contact the paper surface P.

[0006] In the template 30 shown in FIG. 6, a projection 35 is formed on the back surface side of the plate body 31, and the projection 35 causes the back surface forming edge 32 A of the perforated portion 32 to be formed.
Is formed between the sheet and the paper surface P. Here, protrusion 3
5 is integrally formed by injection molding or the like using the same resin material as the plate body 31.

[0005] A template 30 shown in FIG.
Is formed by affixing a film 37 to the back surface of the plate body 31, and a gap can be formed between the back surface forming edge 32A of the perforated portion 31 and the paper surface P by an amount corresponding to the thickness of the film 37. .

According to these conventional structures, since the perforated portion 32 is at a position where it does not directly contact the paper surface P, the ink flowing from the ink pen 38 is drawn into the minute gap between the back surface of the plate body 31 and the paper surface P. This prevents ink bleeding.

[0007]

However, in the case of the template 30 of the type shown in FIG. 5, the cutting portion 33 must be formed for each of the perforated portions 32, which increases the manufacturing cost. There is. In addition, the template 30 itself is configured using the plate body 31 having a plate thickness of about 1 mm, and it is not easy to ensure the cutting precision with high precision. In addition, since the entire back surface of the plate main body 31 except the cutting portion 33 is a contact surface with the paper surface P, the tendency of the template 30 to slide on the paper surface P and contaminate the paper surface P is increased. This tendency is particularly remarkable when a pencil is used at the time of the drawing below.

In the case of the template 30 shown in FIG. 6, since the projection 35 is formed by integral molding, a mold for forming the template 30 is required. In this case, when a variety of templates 30 are manufactured, dedicated molds are individually used. Therefore, a large amount of capital investment is required for the mold equipment, and this disadvantageously comes to be reflected in the selling price. I do.

Furthermore, the template 30 shown in FIG. 7 has the same disadvantages as the template 30 shown in FIG. In addition, since the film 37 is bonded via an appropriate adhesive, there is also an inconvenience that the entire template 30 is warped due to the shrinkage of the film 37 due to the solidification of the adhesive.

[0010]

SUMMARY OF THE INVENTION The present invention has been devised in view of the inconvenience of the prior art, and its object is to prevent not only ink bleeding but also to minimize the possibility of soiling the paper surface. Another object of the present invention is to provide a ruler that can be manufactured at low cost while expanding the applicability when manufacturing various types of rulers.

[0011]

In order to achieve the above object, a ruler according to the present invention is configured such that a printing layer using a photo-curable ink is formed on at least a part of at least one surface of a plate body. Has been adopted. With this configuration, when the plate body is placed on the paper,
A slight gap can be formed between the plate body and the paper surface, and ink is prevented from being drawn into the gap. In addition, in the present invention, it is possible to provide a printing layer on various types of plate bodies by using a pre-formed plate, and it is also possible to suppress the occurrence of warpage as seen in film sticking. Here, as the printing method,
Silk screen can be mentioned. The ruler according to the present invention includes a straight line ruler, a curve ruler, a template, and the like.

[0012]

In the present invention, the printing layer comprises:
It is preferable that the plate is provided on the plate body in a dispersed manner, intermittently or continuously. As a result, the contact area of the plate body with the paper surface can be reduced, thereby effectively preventing the paper surface from being soiled.

The printing layer is preferably formed using an ultraviolet curable ink. As other than the ultraviolet curable ink, there is an evaporative drying type ink, but in the case of the ink, since the solvent component evaporates after printing,
The thickness of the printing layer will be greatly reduced. However, when an ultraviolet curable ink is used, the set thickness of the printing layer can be stably secured, the gap between the plate body and the paper surface can be reliably formed, and a ruler such as a template can be placed on the paper surface. , The template can be easily picked. Here, it is preferable that the layer thickness of the printing layer be 100 μm to 300 μm. 100
If the thickness is less than μm, the ease of picking cannot be expected. On the other hand, the thickness exceeding 300 μm does not provide much benefit, and the stencil manufacturing time becomes longer.

[0014]

An embodiment in which the present invention is applied to a template will be described below with reference to the drawings.

FIG. 1 is a plan view of a template according to the embodiment, and FIG. 2 is a sectional view of a main part. In these figures, a template 10 as a ruler includes a plate body 11 having a thickness of about 1 mm and a plate body 1 having a thickness of about 1 mm.
The plate body 11 includes a plurality of perforations 12 formed corresponding to various characters and symbols, and a printing layer 13 formed on the back surface, which is one surface of the plate body 11. . Here, the plate body 10 is formed of a suitable synthetic resin material, and the perforated portion 11 is formed by a known method.

The printing layer 13 is provided by screen printing. The thickness of this printing layer is 100 μm to 3 μm.
Although it can be arbitrarily determined within the range of 00 μm, in the present embodiment, the print layer 13 is formed with a layer thickness of about 200 μm. The print layers 13 are arranged in a scattered manner, and are formed in a protruding shape at predetermined intervals in the left-right direction with the perforated portion 11 sandwiched between upper and lower positions.

The screen printing in the present embodiment uses a gauze made of a mesh screen woven with chemical fibers such as nylon and polyester or stainless steel wire in addition to silk. A photosensitive agent is applied to the front and back of the gauze a plurality of times, and the photosensitive agent is exposed to light to form a stencil. The stencil is superimposed on the plate body 11 and coated with ultraviolet curable ink from the front side, and then the ink is cured by irradiation with ultraviolet light using a halogen lamp.
Here, it is possible to greatly increase the thickness of the front and back surfaces of the gauze by applying the photosensitive agent a plurality of times, and to form a stencil having a hole depth of 100 μm to 300 μm by exposure, thereby forming a printing layer having the layer thickness. 13 can be provided.

The template 10 configured as described above
In FIG. 2, as shown in FIG.
The dimension of the gap C between the sheet and the paper surface P is about 200 μm,
Since the back side forming edge 12A of the perforated portion 12 is separated from the paper surface P, the ink of the ink pen 15 inserted into the perforated portion 12 does not bleed.

Moreover, since the printing layer 12 is formed in a scattered manner, the total contact area with the paper surface P is reduced, and the template 10 can be smoothly slid on the paper surface P, and the paper surface P is stained. The fear can be reduced as much as possible.

The formation of the printing layer 13 allows the gap C
, It is possible to process even small lot products at low cost.

The shape of the print layer 13 in the present invention is not limited to the above-described embodiment. For example, as shown in FIGS. 3 and 4, the print layer 13 is formed as a print layer 13 extending linearly and continuously. You can also. The printing layer 1
3 may be provided intermittently in a straight or curved direction. Similar functions and effects can be obtained with such a printing layer 13.

The printing layer 13 is not limited to being provided on one surface of the plate body 11 but may be provided on both surfaces. In the configuration in which the print layers 13 are provided on both sides, there is a benefit in the type in which the template 10 can be used on both sides, such as a circular ruler or an elliptical ruler.

In forming the print layer 13, other photocurable inks can be used. For example,
When using visible light or near-infrared light curable ink, expensive devices such as halogen lamps are not required,
Equipment costs can be reduced.

[0024]

As described above, according to the present invention,
In addition to achieving the prevention of ink bleeding due to the fine gap formed between the plate body and the paper surface, printing can be performed using a pre-formed plate, making it possible to manufacture many types of rulers at low cost Can be easily performed. In addition, it is possible to suppress the occurrence of warpage that occurs when the film is attached to the surface of the ruler.

Further, since the printing layer is provided in a scattered, intermittent or continuous manner, the contact resistance with the paper surface is reduced, and the ruler can be smoothly slid on the paper surface, and Can also be reduced.

Further, since the printing layer is formed of an ultraviolet curable ink, the thickness of the printing layer hardly decreases upon curing, and a reduction in the layer thickness due to the evaporation of the solvent, as in the case of the evaporative drying ink, can be avoided. it can. Therefore, a gap between the plate body and the sheet can be reliably formed, and the ruler can be easily picked when the ruler is placed on the sheet.
