Description

[Detailed Description of the Invention] This invention relates to a projection bowling score sheet made of plastic used for writing down the score of a bowling game and enlarging it and projecting it on a projection surface in a bowling alley using a projection device.

Looking at conventionally used projection score sheets, the sheet is highly transparent because it allows the light rays emitted from below to pass through, and the score table printed on the board surface is projected on a distant projection surface. It had to be a board, and its material was usually a plastic sheet such as polystyrene or cellulose acetate.

These conventional sheets are separate sheets for each score table, and because the materials are expensive, it is desirable to be able to use them over and over again, so they are thicker, which makes manufacturing even more difficult. It was going to cost money.

Furthermore, the biggest drawback was that a special volatile writing instrument (usually water-based ink) was required to write the score, and pencils (including mechanical pencils) could not be used.

In other words, with conventional sheets, each time a score was entered, the cap of the writing instrument was removed, and any corrections were erased by wiping them with a cloth or the like.

At that time, the heat from the light source would dry out the tip of the special pen, and if you forgot to put the cap on, you would often be unable to write.

Furthermore, in addition to the heat, the ink from the special pen got on the user's hands, face, clothes, etc. due to the user's sweat, causing discomfort and inconvenience to the user.

Furthermore, the records filled in at that time became unclear, causing trouble.

Furthermore, once a sheet has been used, if it is to be used again, the records must be erased by washing it with water or wiping it dry. This made it uneconomical.

This invention was proposed in view of the above-mentioned circumstances in order to eliminate the drawbacks of conventional score sheets. The purpose of the present invention is to provide a highly useful score sheet that can be used to write information clearly.

FIG. 1 shows an embodiment of the projected bowling score sheet of this invention.

This score sheet A is based on a transparent plastic sheet 1 on which writing can be done with a pencil (including a mechanical pencil), and a score table 2 is printed on the sheet 1.

The plastic sheet 1 is a transparent film made of a material made of a mixture of styrene and ethyl acetate, and the surface thereof is processed with fine irregularities.

According to this, it is possible to clearly write on the base material with a pencil without reducing the transparency of the base material.

The score table 2 is printed on the front or back side of the main sheet.

When printing is performed between two sheets, the top sheet is the sheet of the present invention, and the bottom sheet is a conventional plastic sheet such as polystyrene.

Regarding the format of score table 2 of the main proposal, 21 and 22
This part has no direct relation to the score, but since it is projected by a floodlight, it can be used as an advertisement if you write the sponsor's name or promotional text in this part.

In addition, the same part is colored, and each table has a different color (
If you prepare sheets of various colors (for example, red, blue, yellow, etc.), you can use the sheets of different colors in order to immediately determine which game it is, and it is also aesthetically pleasing.

In addition, since the score sheet A of the present application is disposable and not intended for reuse, it is made thinner than conventional sheets, so it can be easily bent or folded, and it can be made into a long sheet and placed between each table. If a cut (for example, perforation, cut) is made in the material, it can be easily broken.

In that case, as shown in Figure 3, if this long sheet is made into a roll type 3, each sheet will have 4 perforations when used.
, cut 5, and can be used in large quantities.

Since the projection bowling score sheet of this invention has the above-described configuration, it has the following various superior effects compared to conventional score sheets.

■ You can easily and inexpensively obtain scores with pencils, so you don't have to worry about putting on and taking off caps, and if there are any corrections, you can erase them with an eraser. It can be written clearly, and there is no blurring of letters and numbers due to rubbing, user's sweat, etc., or dirt.

■ Since the proposed score sheet is intended to be disposable and not intended for reuse, it can be made thin and the production cost can be reduced.

Therefore, it is possible to use the sheet by winding it up into a long sheet, and by making perforations and cutting it into individual tables, it becomes possible to use a large amount of the sheet.
