Plate having diffused reflection material and method for manufacturing the same {Plate having diffuse material and Method for manufacturing the same}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a plastic plate, and more particularly, for reading with attached diffuse reflection material for reading or underlining a line formed by letters written in a book or underlining a word, phrase or sentence. The indication plate and a method of manufacturing the indication plate.

In general, readers (called readers), such as students or examinees, read carefully. As shown in Fig. 1, in the case where the letters written in the book 12 are small in size and narrow in line, in order to easily read the line currently being read from the next line, and to draw lines where necessary, such as words, phrases or sentences. Often plastic rulers 11 are used.

However, since the conventional plastic ruler 11, which is readily available in stationery, is a stationery used to draw or measure lines, the reader often cuts the length of the ruler to fit the width of the book 12. When reading a book placed on the book with the person who fits the width of the book, there is a problem that the reader is blinded and unable to read the book for a long time or concentrate his mind because of the light reflected from the surface of the book. This will be described in more detail as follows.

As shown in FIG. 2, the light I1 emitted from the light source and incident on the book is incident on the vertical line of the book at a large angle of incidence angle a, and then is mostly diffusely reflected and reflected light at the reflection angle a '. (R1) enters the reader's eyes. At the same time, light I2 is incident on the surface of the plastic ruler from the light source, and light R2 reflected by the incident light I2 on the surface of the plastic ruler enters the reader's eyes.

Since the light R1 reflected from the surface of the book is one of the diffusely reflected light, its intensity is quite small and thus does not irritate and dazzle the reader's eyes. On the other hand, the light (R2) reflected from the smooth surface of the plastic ruler enters the reader's eye with a light intensity almost equal to the intensity of the incident light (I2) according to the general law of reflection and thus stimulates the reader's eye.

Thus, the reader should try not to consciously recognize the dazzling light reflected from the surface of the plastic ruler when reading it with the ruler. Usually, you use it for a while to draw a line in the area. While reading, this behavior of the reader decreases mental focus and speeds up reading.

In order to solve this problem, conventionally, no technique is proposed that does not dazzle the reader or the user with a tool such as a reader or a reader.

As shown in FIG. 16, the light i1 coming from the light source and incident on the book is mostly reflected by the reflection angle b 'after being incident on the vertical line on the surface of the book at a large incident angle b. R1) enters the reader's eyes. By the way, the light i2 incident from the light source onto the surface of the reading indicator plate on which the diffuse reflection material is attached is diffusely reflected on the surface of the diffuse reflection material of the reading indicator plate on which the diffuse reflection material is attached, and the light diffused into the reader's eyes enters.

Since the light r1 reflected from the surface of the book is one of the diffusely reflected light, its intensity is quite small and thus does not irritate and dazzle the reader's eyes. In addition, the light scattered from the surface of the diffuse reflection material of the reading indicator plate with the diffuse reflection material according to the present invention is quite small in intensity and thus does not irritate and dazzle the reader's eyes.

Therefore, the reader can read the book continuously using the reading indicator plate with the diffuse reflection material according to the present invention, while the reader reads the row with the reading indicator plate with the diffuse reflection material. You can line it up.

An embodiment of applying a reading indicator plate with a diffuse reflection material according to the present invention to a ruler will be described with reference to the accompanying drawings.

17 is a cross-sectional view of a ruler with a diffuse reflection material according to the present invention.

The ruler (1-1) to which the diffuse reflection material is attached is attached to the bottom plate with one longitudinal edge and the bottom plate having M length and N height by using a bonding agent on the other side of the bottom plate. Diffused reflection material.

Here, the length L and the inclination angle c of the inclined surface are determined by the length M and the height N of the base side. In this embodiment, the thickness of the bottom plate is 4 mm, M is 8 mm, N was implemented to be 2 mm. M is where the scale is drawn.
