Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a removable plastic film lyrics sheet for use in a songbook used for karaoke singing.

[Prior Art] Conventionally, when singing at karaoke, a songbook consisting of a paper lyric sheet or a lyric sheet in which paper with lyrics printed on it is inserted into a plastic film bag have been used.

Since a songbook for karaoke singing contains a very large number of lyrics, the songbooks made up of the two types of lyric sheets mentioned above are both very thick, and it is necessary to divide the songbooks into a large number of volumes. As a result, it takes time to search for desired lyrics, and it is often inconvenient that the user is unable to arrive in time for the start of the karaoke song.

In addition, it is necessary to rearrange each lyric sheet according to the popularity of the song, and each lyric sheet must be structured so that it can be attached and detached. Among these structures, the simplest and most commonly adopted method is to provide holes along the sides of each sheet and insert metal rods into the holes.

However, if this method is used for lyric sheets, especially lyric sheets made of thin plastic film, karaoke songbooks will turn over the pages very frequently.
There is a drawback that the sheet tears at the hole and the lyrics sheet is easily torn.

[Problems to be solved by the invention] By making the lyrics sheet very thin and durable, the invention makes it possible to make the poetry booklet thinner and satisfy a large number of demands with a small number of books. To provide a lyrics sheet that allows easy searching for lyrics and does not have the defect of tearing from the binding part when it is detachably bound.

[Means for solving the problem] The present inventor noticed that lyrics sheets made of thin plastic film can be made thinner and more durable than lyrics sheets made of paper, and developed a lyrics sheet made of plastic film. We considered creating a lyrics sheet. However, if the lyrics are simply printed on a plastic film, the printing may peel off or smudge if it becomes contaminated with water or alcohol, or due to friction or adhesion between lyrics sheets.

The inventor proposed that the above object could be achieved by laminating a thin plastic film over the print of the lyrics to protect the print and heat-melting the periphery of the binding hole to prevent it from tearing. This led to the discovery of this idea.

In other words, the present invention has lyrics printed on both sides.
A thermoplastic plastic film 1 is laminated on both sides of a rectangular opaque sheet 2 made of a thermoplastic plastic film, and a plurality of thermoplastic film 1 are printed at regular intervals along the binding edge of either the left or right side of the rectangle. A heading tongue piece 3 is provided with a binding hole 5, the periphery of the hole is reinforced by heat melting, and extends continuously to the side opposite to the binding side or at least one of the upper and lower two sides. , 4 is provided.

[Function] The opaque sheet 2 on which lyrics are printed used in the present invention is made of an opaque thermoplastic plastic film, and so-called synthetic paper may also be used.

The plastic film can be made opaque by, for example, foaming, adding pigments, coating with matte ink, or the like. The color of the opaque sheet is not particularly limited, but it is usually white.

In the present invention, lyrics are printed on both sides of the opaque sheet 2.

The plastic film 1 for lamination used in the present invention is a transparent, extremely thin film that protects the printed surface from friction and provides water resistance.

The lyrics sheet of this invention is made of a triple-layered laminated film, but each film is very thin, so
The sheet is much thinner than when printing paper is used.

Since the periphery of the binding hole provided in the lyrics sheet of the present invention is reinforced by thermal melting, the sheet will not tear from the hole.

Thermal reinforcement of this hole can be achieved by punching the hole with a heated round-blade die.

Lyrics sheets can be manufactured by various methods, but it is convenient to manufacture them by thermally cutting each page of a long triple-layered film laminated to a long printed plastic film.

At that time, printing was also applied to the tongue piece 3 for the heading,
It is durable because the heading tongue piece 3 is continuously extended from the lyrics sheet at the end of each page when thermally melted.

These headline tabs 3 and 4 make it very easy to search the lyrics sheet.

The heading tabs 3 and 4 are easily bent and torn in conventional paper lyrics sheets, and even if heading tabs are provided in the case of conventional plastic film bags, if printed on this surface, the It tends to flake off for the same reason.

Since the lyrics sheet of the present invention is made of plastic film, static electricity is likely to occur. In order to prevent the generation of static electricity, it is convenient to add an antistatic agent to the film used in the present invention.

[Example] The present invention will be described in more detail with reference to the drawings of the example.

The lyrics sheet of the present invention shown in FIGS. 1 and 2 is made by punching out a rectangular shape from an opaque sheet 2 with lyrics printed on both sides, which is laminated with thermoplastic film 1 on both sides. is heated and the periphery of the lyrics sheet is fused. Since the edges are fused, the laminate will not peel off.

Three binding holes 5 are provided along the binding side 6 of the lyrics sheet of the present invention. The periphery of this hole is also reinforced by thermal melting.

On the side opposite to the side 6, a heading tongue piece 3 is continuously extended.

In the embodiment shown in FIG. 3, the lyrics sheet is a vertically long rectangle, and heading tabs 3 and 4 are provided on the right side and the top side. By using two types of heading tabs, indexes can be created from two different angles, such as by song title and by singer.

By providing a plurality of such heading tabs, it is also possible to search for desired lyrics without relying on the table of contents.

[Effect of the invention] If you use a thin lyrics sheet like the one of this invention,
It is convenient to search for lyrics because the collection of poems does not become bulky and therefore does not span multiple volumes. On the other hand, when a thin lyrics sheet is bound in a detachable manner, it is durable because it does not tear from the binding hole, and it has excellent water resistance and friction resistance, so the poetry book will last a long time.

Furthermore, it is advantageous that a desired lyric sheet can be quickly searched for using the heading tongue piece 3.

[Brief explanation of the drawing]

FIG. 1 is a front view of a lyric sheet according to an embodiment of the present invention, FIG. 2 is a longitudinal sectional view thereof, and FIG. 3 is a front view of a lyrics sheet according to another embodiment of the present invention. The symbols in the figure are 1: opaque sheet with printed lyrics, 2: laminated protective film, 3, 4: headline tongue, 5: binding hole, 6: binding side.
