Description

Reading plate having scattered-reflective material with projections and manufacturing method thereof {Reading plate having scattered-member of low reflectivity, with protrusions, and method approx}

The present invention relates to a reading stationery, and more particularly, a reading with a low reflectivity reflective material having projections to read or underline a line formed by letters written in a book or to underline a word, phrase or sentence. It relates to an indication board for the same and a method of manufacturing the same

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.

The present invention allows a reader to read the lines formed by the letters in a book, and to absorb, scatter, and diffuse incident light, and to prevent slipping from the reader's hand. An object of the present invention is to provide an indicator plate and a method of manufacturing the same.

The present invention provides a low reflectivity reflective material with projections that allows the reader to trace the lines of letters in a book, underline them, absorb, scatter and diffuse incident light, and prevent slipping in the reader's hands.
