Description

[Detailed explanation of the idea] The present invention relates to a portable office case.

Generally, office cases for carrying and keeping notebooks and other documents are known, and various small and flat card-type electronic calculators (so-called calculators) are also commercially available.

However, although both are often used together in practice, they are physically completely separate and independent, so the user must carry both separately, which is extremely inconvenient. Also, while carrying the calculator, the calculator may be improperly bent, dropped, or
There is always the fear of losing it. Furthermore, when the calculator is not in use, foreign matter such as dust adheres to and accumulates on the surface of the calculator, causing trouble in cleaning and deterioration of functionality.

In addition, as shown in Japanese Utility Model Application No. 56-168927, a storage space is provided in a position facing the outer surface of a bag, etc., and a rotatable calculator is provided in this space, so that the calculator can be rotated when used. Although some devices are designed to be exposed, such a structure has the disadvantage that it is difficult to make the device compact and flat, and it becomes bulky.

The present invention is intended to improve these problems, and its specific configuration will be described in detail based on the illustrated embodiment as follows.

That is, Figures 1 and 2 show an example of an office case to which the present invention is applied, showing the closed state when carried and the folded state when used. The main body of the case is made of a sheet material similar to that of , which itself includes a reinforcing core plate a, and a pair of front and back decorative covering plates b that sandwich this.
It is finished in the form of a relatively thick and hard laminated plate from c. However, as long as the case body A has enough hardness and thickness that it does not bend easily, it does not necessarily have to be in a laminated form.

Due to its function, the case body A above is
1, a back cover version 12, and an inside cover version 13. That is, a front cover plate part 11 of approximately the same size as this is continuously formed at one lateral position of the back cover plate part 12, and a Notes and other documents M can be freely inserted and held in a pocket or the like.

Further, the inner cover plate part 13 is slightly smaller in size than the back cover plate part 12, and is also continuously formed at the other lateral position in the back cover plate part 12. 14 and 15 are for the back cover version part 12,
This is a bending guide line for folding the front cover plate part 11 and the inner cover plate part 13 so that they can be opened and closed, and is a bending guide line for the above-mentioned document M.
A back portion 16 of a constant width corresponding to the thickness of the back portion 16 is also ensured. 17 and 18 are the front cover plate section 1 which is opened and closed.
1 and the inner cover plate part 13 are sealed and fixed in mutually corresponding positions, and by their matching, they are held in the closed state as shown in FIG. 1. However, it is of course possible to use eyelet hooks, fastening bands, or other fixing devices in place of the magnets 17 and 18 to perform the same function. At the so-called engraving positions of the bending guide lines 14 and 15,
Needless to say, the reinforcing core plate a is not enclosed.

B is a small, flat electronic calculator (so-called card type calculator) which is embedded and integrated into the inner cover plate part 13 of the case body A, as shown enlarged in Figs. 3 and 4. The reinforcing core plate a is positioned and fixed in the enclosure S defined by cutting out a part of the reinforcing core plate a. Reference numeral 19 indicates a liquid crystal display section of the electronic calculator B, and 20 indicates a light-receiving element as well, and windows 21 and 22 located corresponding thereto.
is formed inside the inner cover plate part 13, penetrating through the cover plate c of the case main body A, which forms the surface thereof.

Therefore, when the inner cover plate part 13 is folded open from the back cover plate part 12 as shown in FIG. 2, the electronic calculator B
can be automatically operated and used at any time,
On the other hand, when it is in the closed state as shown in Figure 1, it can be easily carried around without having to operate it unnecessarily. However, if a calculator incorporating a sheet type battery or the like is adopted instead of the light receiving element 20, the installation of the window 22 may be omitted.

In addition, the display 23 of numbers and various symbols for guiding the pressing position of the electronic calculator B is displayed on the case body A.
It is integrally applied to the covering plate c, which forms the surface thereof, by printing, pasting a sticker paper, or other means. In other words, the electronic calculator B has a built-in piezoelectric element, and therefore, it can be used properly as it is by pressing the surface of the case body A with a fingertip based on the guide display 23 of the pressing position. It is becoming possible to do this. Since it does not protrude tall like a separate push button in the electronic calculator B, the case main body A does not need to be stretched out unnecessarily, and is useful as a portable type.

In that case, in the illustrated example, the guide display 23 is provided on the surface of the inner cover plate part 13 that can be folded open from the back cover plate part 12, and is pressed from inside, so that the case body A There is no risk of impairing the cosmetic effect of the external appearance, and furthermore, the electronic calculator B can be protected from foreign substances such as dust. In this sense, the guide display 23 and the windows 21, 22 may be provided on the inner surface of the front cover plate part 11, which can also be folded open, or on the inner surface of the back cover plate part 12. The case body A
Of course, the opening/closing manner is not limited to that shown in the drawings.

As described above, in the present invention, as a portable office case, a small and flat electronic calculator B is embedded and integrated into the inner surface of the foldable cover plate part of the case body. Electronic calculator B
Since the pressure positioning guide display 23 and the window 21 of the liquid crystal display section 19 are provided on the surface of the case body A itself, the problems mentioned at the beginning can be solved with its simple structure. It has the effect of being extremely convenient and portable.

In other words, since the electronic calculator B is enclosed in the case body A in the form of a small and flat card, there is a risk that the case body A may be stretched out or its external cosmetic effect may be deteriorated. Moreover, you can carry it around and use it for calculations without getting in the way. This will effectively prevent the calculator from falling off, becoming loose, forgetting to bring it with you, or being lost.

In particular, if the card-type electronic calculator B with the light-receiving element 20 as shown in the illustrated embodiment is enclosed and installed in a foldable inner cover plate part 13, etc., and configured so that it can be used by pressing from inside. For example, it is not only convenient to use, but also improves the cosmetic effect, prevents unnecessary operation of the electronic calculator B when not in use, and further enhances the protection against foreign substances. Furthermore, if the case body A is in the form of a laminate including a reinforcing core plate a, the hardness is determined so that it does not bend easily, and the enclosure chamber S of the electronic calculator B is partitioned by the notch of the reinforcing core plate a. Since the preparation of the case body A and the work of enclosing the electronic calculator B therein can be done efficiently, it can be said to be even more profitable.
