Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention typically relates to a booklet explaining the operation or handling of various electronic devices,
More specifically, it relates to a booklet for handling instructions which is lightweight and has excellent page turning property.

[0002]

2. Description of the Related Art In recent years, various electronic devices such as personal computers, electronic organizers, electronic games, and mobile phones have been expanding their functions day by day. And weight reduction. On the other hand, in the instruction booklet in which the functions and operating methods of these electronic devices are printed, the information to be posted increases with the expansion of the functions of the electronic devices, so that the number of pages is inevitably increased. Generally, since this kind of explanation booklet is usually A4 size, the increase of the information to be published inevitably increases the number of pages, and thus also the weight of the booklet. By the way, the mass of the main body of the mobile phone is 50 to 60 g at the minimum and about 200 g at the maximum, whereas the mass of the instruction booklet is at least twice the mass of the main body.

One of the means for avoiding an increase in the mass of the instruction booklet is to separate the instruction booklet itself.
However, considering that various electronic devices are always sold as a set with a manual, dividing the explanation booklet into separate volumes does not lead to weight reduction of the sales set. Further, from the viewpoint of the user of the electronic device, although the instruction booklet is not always used, it is worried that it may take time to find the necessary information.

Another means for avoiding an increase in the mass of the instruction booklet is to reduce the weight of the paper used for the instruction booklet. To reduce the weight of the paper, specifically, it is to reduce the paper thickness. However, there is a concern that the paper loses its bulk and hinders page turning. Further, the reduction of the paper thickness not only impairs the sense of quality as a result of decreasing the opacity of the paper, but also makes it difficult to read the print information in the explanation booklet which is usually double-sided printed. There is a harmful effect.

In order to reduce the weight of the paper, it is common to use a bulky paper as the base paper. The bulky base paper is made from a raw pulp having a high freeness beaten under relatively mild conditions. Can be obtained by doing. However, this type of bulky base paper has insufficient surface smoothness and barrier properties and is often impregnated with the coating liquid. Therefore, a coated paper having good printability is obtained from the above-mentioned base paper. Difficult to do. Then, in order to improve such inconvenience, when the raw paper is processed by strengthening the linear pressure in the machine calender, the fact is that the bulk of the paper is reduced.

As a method for minimizing the decrease in bulk due to calendering and increasing the bulk without impairing the surface smoothness and barrier properties of the base paper, a method of thermal calendering with a high temperature roll or immediately before calendering The method of giving surface smoothness and barrier property to the base paper with
JP-A-4-361695 and JP-A-6-73685.
It is disclosed in the publication. However, even if these conventional techniques are adopted, it is difficult to obtain a sheet that is bulky and has a good turning property.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a handling instruction booklet which is lightweight, has excellent page turning properties, and is in a good printed state.

[0008]

A booklet for handling instructions according to the present invention is a booklet in which a table of contents, a text and an index are printed, and the stock of the paper constituting the booklet is waste paper pulp 10.
Becomes 0%, the paper 115 sheets of thickness when measured under a pressure of 147KPa is below 0.75 cm, Clark stiffness of the paper longitudinal 16~25cm ^3/100, the horizontal 8~12cm ^3/100 The Taber rigidity defined by JIS P 8125 when 10 sheets are overlaid is 0.34 to 0.40 mN · m in the vertical direction and 0.24 to 0.3 in the horizontal direction.
It is characterized by being in the range of mN · m. The instruction booklet of the present invention has an A4 size and a weight of 200 g.
The following is preferable. Generally, a booklet for handling instructions is usually provided with a cover, but the mass of the booklet in the present invention means the mass excluding the cover.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In the booklet for explaining the handling of the present invention, waste paper pulp is used for all the stock (raw material for papermaking) of the paper. The raw material of the waste paper pulp may be any of newspapers, magazines, high-quality paper, and the like, and waste paper pulp having a whiteness of 65% or more by deinking / bleaching can be used as a raw material for papermaking. It is not only preferable in terms of environmental protection to cover 100% recycled pulp for the paper stock, but it is also advantageous for making the paper bulky.

In order to improve the page turning property without deteriorating the printability of the paper, it is important that the Taber rigidity and the Clark rigidity of the paper are within a predetermined range. Inorganic fillers are internally added during the papermaking. Among the inorganic fillers, calcium carbonate is effective in improving whiteness and opacity and is economically preferable because it is inexpensive. Furthermore, when a small amount of titanium oxide is used in combination, it is effective in improving the opacity.

In the production of the paper of the present invention, a sizing agent, a paper strengthening agent, a yield improving agent and the like can be added within the range of adverse effects on the Taber stiffness and Clark stiffness defined in the present invention. There are no particular restrictions on the papermaking chemicals. When making paper, a known paper machine, for example,
Various paper machines such as long net, gap homer, and cylinder can be used.
