Description

  The present invention relates to a scale generating sheet that can easily reproduce the sound of a scale.

  Conventionally, a method of generating a sound by providing an uneven portion on the surface of an object and rubbing it with a toe or the like has been implemented. For example, as an improvement to the Thomas Edison gramophone type, the “vertical embossing system” by Hübner Stefan has been proposed.

  Further, a method of providing audio information by embossing has been proposed as an “embossed sound track” (see Patent Document 1).

As another method, a method of providing an audio spectrum by offset printing or a bubble jet (registered trademark) method has been proposed as a “natural frequency material synthesis method” (see Patent Document 2).
Special table 2001-510616 gazette WO00-72304

  However, in the method of “embossed sound track” of Patent Document 1, an uneven shape is formed by embossing, but when formed on a soft base material, the uneven shape is likely to collapse due to elastic deformation over time. The base material is limited to hard materials such as lacquers, coatings, plastics, metals, ceramics, etc. Also, because the mold for embossing is expensive, there is a problem in terms of cost, and embossing is more productive There is a problem that is low.

  Further, the method of “Sound generating device and method for manufacturing the same” in Patent Document 2 has a problem that the material of the paper to be printed is limited because the reproduced sound becomes clear in proportion to the resolution. Even if a material with a high resonance effect is selected, with the offset method, the ink thickness that can be applied is several microns, so there is a limit to the volume of reproduced sound. Even with the ink jet method, UV ink reaction type drop Some heads can thicken ink like the on-demand system, but the line width and thickness accuracy as screen printing cannot be reproduced, and the reproduced sound is unstable.

  The present invention has been made in order to solve the above-mentioned problems, and a scale generation in which a convex portion in a sound expression area in which information for generating sound is incorporated is formed by a printing method instead of embossing. The purpose is to provide a sheet.

  As a result of intensive studies on the means for solving the above-mentioned problems, the present inventor has formed a plurality of sound expression regions expressing a scale on a base, and the sound expression regions have UV curable properties. Linear convex portions made of resin or EB curable resin are provided at an equal pitch, and the pitch width is defined by adding the width of the convex portion and the interval between the convex portion and the convex portion, and the width of the convex portion is predetermined. Generation of the scale, wherein the pitch interval between adjacent sound expression areas is successively reduced by a factor of 1 / 1.059 times, and a scale that rises by a semitone by a scratch such as a claw at a constant speed is generated. It is a sheet.

  Moreover, the height of a linear convex part shall be 0.1-0.6 mm.

  As described above, according to the scale generating sheet of the present invention, the sound expression area in which the information for generating sound is incorporated is not embossed but ink of UV curable resin or EB curable resin is used. The convex portions can be formed by gravure printing or silk screen printing. Moreover, since the height of the convex portion can be set in the range of 0.1 to 0.6 mm by the gravure printing method or the silk screen printing method, there is an effect that the expressed sound can be increased. .

It is the schematic of the scale generation sheet | seat of this invention. It is a schematic sectional drawing of the sound expression area | region which comprises the scale generation sheet | seat of this invention.

  In the scale generating sheet 1 of the present invention, as shown in FIG. 1, a plurality of sound expression regions 20 are formed on a base 10, and convex portions T are formed in the sound expression regions 20 as shown in FIG. 2. It is the structure which was made. Below, the base | substrate 10, the sound expression area | region 20, and the convex part T are demonstrated.

First, the base is not particularly limited as long as the convex part can be printed, and can be appropriately set according to the purpose. An example of the base 10 is as follows.
1. Base material layer 11
2. Base material layer 11 + printing layer 12
3. Base material layer 11 + printing layer 12 + protective layer 13
(Base material layer)
The material of the base material layer 11 is not limited to paperboard, but includes a polypropylene (hereinafter referred to as PP) sheet, a polyethylene terephthalate (hereinafter referred to as PET) sheet, a polyvinyl chloride (hereinafter referred to as PVC) sheet, cardboard and the like. Among them, from the viewpoint of good acoustics, corrugated cardboard, bulky base paper, tracing paper, and the like that have good sound resonance and conductivity are preferable. The thickness is not limited to the embodiment, and can be appropriately set according to the purpose.
(Print layer)
The printing layer 12 is a layer on which a pattern is printed, and the type of ink can be appropriately set according to the pattern.
(Protective layer)
The protective layer 13 is a layer that protects the printing layer 12, and examples of the material include PP, PET, polycarbonate, PVC, and the like, and PP and PVC are preferable from the viewpoint of close contact with the substrate. A thickness of 5 to 100 μm can be used.

  Next, the sound expression area 20 is an area in which information for expressing one sound is incorporated, and a plurality of linear convex portions T are provided. The number of the linear protrusions T can be set as appropriate according to the pitch of the sound. If the width of the convex portion T is a and the interval between the convex portion T and the convex portion T is b, the pitch interval c is a + b, the width a of the convex portion is constant at a predetermined width, and the adjacent sound The pitch interval c of the expression area 20 is sequentially reduced to 1 / 1.059 times to form a plurality of sound expression areas 20 representing a musical scale. A musical scale can be expressed by scratching the plurality of sound expression regions 20 at a constant speed.

  In the sound expression region 20, a plurality of linear protrusions T are provided as appropriate so that the linear protrusions T are parallel to the vertical sides and the linear protrusions T are parallel.

  Further, the interval b between the convex portion and the convex portion and the interval d between the sound expression region 20 and the sound expression region 20 can be appropriately set within a distance that a person can scratch with a nail or the like. Specifically, the pitch interval c for generating a scale is set to 12 scales on a uniform scale in the case of Western music, and can be set as shown in Table 1. Generally, 8 scales are displayed, and 8 scales of do (whole sound), re (whole sound), mi (semitone), fa (whole sound), so (whole sound), la (whole sound), si (semitone) do.

  Furthermore, the shape of the sound expression area 20 can be a square, a triangle, a circle, an ellipse, or the like. In addition, it can be a designed shape such as a star shape.

ピッチ間隔の設定方法（ドを１ｍｍとした場合）
さらに、音発現領域上には線状の凸部を設け、この線状の凸部に略直角方法に音発現領域を指の爪等でスクラッチすることにより固有の音が発生される。この凸部は、ＵＶ硬化性樹脂もしくはＥＢ硬化性の樹脂を使用して、グラビア印刷法もしくはスクリーン印刷法により形成される。また、凸部の高さは０．１〜０．６ｍｍの範囲で適宜設定することができ、０．１ｍｍ未満ではスクラッチしてもスクラッチするものが引っ掛からないため、音が発生しにくくなり、０．６ｍｍ以上ではスクラッチしたときに凸部が破損しやすくなり、形状安定性の点で好ましくない。凸部の幅ａは目的に応じて適宜設定することができる。また、凸部の幅ａは、０．１〜２．０ｍｍの範囲で適宜設定することが好ましく、０．１ｍｍ未満ではスクラッチした時には、凸部が破損しやすくなり、２．０ｍｍ以上ではスクラッチした時に音が出にくくなる。

How to set the pitch interval (when the distance is 1 mm)
Furthermore, a linear protrusion is provided on the sound expression area, and a specific sound is generated by scratching the sound expression area with a fingernail or the like in a substantially right angle manner on the linear protrusion. The convex portion is formed by a gravure printing method or a screen printing method using a UV curable resin or an EB curable resin. Further, the height of the convex portion can be set as appropriate within a range of 0.1 to 0.6 mm, and if it is less than 0.1 mm, the scratching object will not be caught even if it is scratched. When the thickness is 6 mm or more, the convex portion tends to be damaged when scratched, which is not preferable in terms of shape stability. The width a of the convex portion can be appropriately set according to the purpose. Further, the width a of the convex portion is preferably set as appropriate within a range of 0.1 to 2.0 mm. When the scratch is less than 0.1 mm, the convex portion is easily damaged, and when it is 2.0 mm or more, the scratch is scratched. Sometimes it becomes difficult to make sound.

  The UV curable ink for providing the convex portion is a mixture of at least a polymer, a monomer, and a photopolymerization initiator. Examples of the polymer include methyl acrylate, methyl methacrylate (hereinafter, “methyl acrylate” and “methyl methacrylate”). "Is represented as" (meth) acrylate ". The same applies hereinafter.), Ethyl (meth) acrylate, n-butyl (meth) acrylate, hexyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, lauryl ( So-called monofunctional monomers having one polymerizable vinyl group in one molecule such as meth) acrylate, isobornyl (meth) acrylate, dicyclopentenyl (meth) acrylate, N-vinylpyrrolidone, styrene; ) Acrylate, propylene Recall di (meth) acrylate, neopentyl glycol di (meth) acrylate, 1,6-hexanediol di (meth) acrylate, diethylene glycol di (meth) acrylate, triethylene glycol di (meth) acrylate, dipropylene glycol di (meth) A so-called bifunctional monomer having two polymerizable vinyl groups in one molecule such as acrylate; trimethylolpropane tri (meth) acrylate, pentaerythritol tetra (meth) acrylate, dipentaerythritol hexa (meth) acrylate, tris Examples thereof include so-called polyfunctional monomers having three or more polymerizable vinyl groups in one molecule such as (acryloxyethyl) isocyanurate.

  Furthermore, oligomers such as unsaturated polyesters, polyester (meth) acrylates, polyether (meth) acrylates, polyol (meth) acrylates, epoxy (meth) acrylates, and urethane (meth) acrylates can be used as oligomers.

Specific examples of the present invention will be described below.
