Abstract

(57) [Summary] [Purpose] To provide a book that allows students to memorize important matters of two strains by replacing the filter. [Structure] A part 1 of the important matter is printed in black or other dark and dark colors, a dark red mask print 3 is applied to this, and other important matter 2 is printed in light red. Mask printing applied to a part of the above important matters is made red, and other important matters are also printed in the same color red. [Effect] By using the red and blue filters interchangeably, important matters of the two strains can be made unreadable, and the important matters of the two strains can be intensively learned. The same effect as described above can be obtained by one-color printing, and the printing cost can be reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to books.

[0002]

[Prior art]

 In the past, some books, especially learning books, were printed with important items and were covered with filters of similar colors to make the important items unreadable and used for memorization learning.

[0003]

[Problems to be solved by the device]

 As a filter used for conventional learning books, it is convenient to use a filter that is generally available on the market in terms of price and availability.However, a filter that is easily available on the market is red, There are only blue, green and yellow ones. When an important matter is printed in red and covered with a red filter, the important matter can be made relatively unreadable, but the important matter is printed in blue or green and covered with a blue or green filter. Cannot easily make the important matters unreadable. In addition, when important matters are printed in yellow, there is a drawback that the important matters are difficult to read and fade with the passage of time without covering the filter. Therefore, conventional learning books use only the type that prints important items in red and covers them with a red filter. However, in this case, when learning history, for example, only the important matters of a single strain, such as the case name or the year, can only be read, and it is used only for memorization learning of the important matters of a single strain. Therefore, it is not possible to learn by memorization about important matters of two systems such as case name and year name or person name and case name.

It is an object of the present invention to eliminate such inconvenience and to provide a book in which the memorization learning of important matters of the two system species can be performed by exchanging the filter.

[0005]

[Means for Solving the Problems]

 The book of the present invention prints a part of the important matters in black or other dark and dark colors, masks this with dark red, and prints other important matters in light red, and The above-mentioned purpose was achieved by printing the mask printed on red in red and printing other important items in the same red color. Furthermore, it is convenient to attach red and blue filters to the books.

[0006]

[Action]

 The above book has the first important item and the second important item according to the type of important item. The letters and symbols of the first important item are printed in dark and dark colors, and a dark red mask is printed on this. Since the 2nd important point is the letters and symbols printed in light red, the first important point is clearly readable while looking through the filter by covering the entire page with a red filter. The matter becomes unreadable. Next, if you cover the entire page with a blue filter and look through the filter, the entire mask-printed part becomes dark or dark such as black, making the first important item unreadable, while the second important item is black. It becomes readable as the characters such as. In this way, the second important matter becomes undecipherable over the red filter, and the first important matter becomes unreadable over the blue filter, and the memorization learning of the important matters of the two strains is effective only by replacing the filter. You can do it. Further, the same applies even if the dark and dark characters of the first important item are printed with a red mask and the characters of the second important item are printed in the same color.

[0007]

【Example】

 The case where the embodiment of the present invention is applied to a history learning book will be described with reference to the attached drawing. In FIG. 1, some of important characters and symbols are dark and dark colors such as black, dark green and dark blue. It is printed with a dark red mask print on it and other important matters such as letters and symbols are printed in a light red color. Here, the symbols 1, 1, 1, 1 are printed in black. It shows the first important item consisting of an important year number to remember, and dark red mask printing 3, 3 is applied. Reference numerals 2, 2 and 2 indicate the second important items such as the case name and the person's name, which are printed in light red.

When the book having the above structure is covered with a separately prepared red filter and viewed through the filter, the second important matters 2 and 2 become unreadable as shown in FIG. 2, while the first important matters 1, 1 and Since item 1 is readable, intensive learning of only the second important item is possible. Next, looking over the blue filter, which was also prepared separately, as seen through the filter, as shown in FIG. 3, the entire mask prints 3 and 3 became black and the first important matter became unreadable, while the second important one Since the matters are legible, intensive learning of only the first important matters becomes possible.

Further, if the mask printing 3 applied to the first important matters 1, 1, 1 is printed in a red color lighter than the above, and the second important matters 2, 2, 2 are printed in the same color as that, the red filter The second important matter 2 becomes unreadable and the blue filter can make the first important matter 1 unreadable, and as a result, intensive learning of only the second important matter and the first important matter becomes possible. .

It is desirable that the above-mentioned red and blue filters be bound so that they can be cut freely during bookbinding.

[0011]

[Effect of device]

 As described above, according to the present invention, a part of important items is printed in dark and dark colors, a dark red mask is printed on this, and other important items are printed in light red. Interchangeable use has the effect of making important matters of the two strains unreadable and allowing intensive learning of important matters of the two strains. In addition, by printing the mask printing on the important matters in red and printing the other important matters in the same color, it is possible to obtain the same effect as the above by making a one-color printing, and there is an effect of reducing the printing cost. Furthermore, by attaching the red and blue filters to the book, it is convenient and convenient for the user to prepare these filters separately.
