Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mini calculator having a calculator body and an opening / closing lid provided with a storage portion for seals such as photographs.

[0002]

[Prior art]

 Conventionally, mini calculators are equipped with a solar cell as a power source, operation keys for inputting numerical values and calculation symbols, and a display window for outputting calculation results on the surface of the plastic case body. It is known that it is stored in a bag-shaped vinyl case or a notebook-type storage case with an opening / closing lid.

[0003]

[Problems to be solved by the device]

 However, in the conventional mini-calculator, it is used by taking it out of the storage bag or by opening the notebook type opening / closing lid, but after use, it is stored in the storage bag or the opening / closing lid is closed. Since it is stored in the storage case, the storage case merely serves as a case for storing and protecting the mini calculator, and the mini calculator itself also serves only as a calculator, and therefore, the bag when not in use. It is often stored in the room or in a desk, and when it is used, it often becomes useless by searching around for where it is.

The present invention has been made in order to meet such a requirement, and its purpose is to have not only a function as a computer but also a practical function and a decoration function, and it is necessary to always have it nearby. It is to provide a mini calculator that can be used immediately at any time.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the mini calculator of the present invention comprises a calculator main body having operation keys and a display window on the surface, and an openable and closable one side edge of the calculator main body. An opening / closing lid for protecting the surface is provided, and the opening / closing lid is provided with a storage portion for seals such as photographs.

According to a second aspect of the present invention, an opening is formed in the opening / closing lid, and a transparent member is attached to the opening, and the storage is provided inside the opening / closing lid at a position overlapping the opening. And an engaging hole for opening and closing is formed in the back cover of the storage section.

According to a third aspect of the present invention, a key holder is provided at one end of the calculator body.

According to a fourth aspect of the present invention, the calculator main body includes a solar battery or a storage battery as a power source.

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. 1 and 2 show an embodiment of a mini calculator according to the present invention, in which reference numeral 1 is a calculator main body. The calculator body 1 has a thin plate-like shape and is sized to fit in the palm of a hand, for example, about half the size of a business card, and an opening / closing lid 2 is integrally and openably connected to one side edge of the calculator body 1. ing.

A solar cell 3, operation keys 4, and a display window 5 are arranged on the surface of the calculator main body 1, and electric parts such as a circuit board (not shown) are housed inside. A storage battery may be used as the power source. Further, a key holder 7 is provided on the edge of the calculator body 1 on the side of the opening / closing lid 2. The key holder 7 is attached to the edge of the calculator body 1 via an attachment ring 8, and a support ring 9 for assembling a key is arranged at the tip.

In the mini calculator 1, when the opening / closing lid 2 is opened, the solar cell functions, and when data is input from the operation keys 4, the result is displayed in the display window 5. It should be noted that since the entire mini calculator is so large that it can be placed on the palm of the hand, it is preferable to operate the operation keys 4 with the tip of a mechanical pencil.

The opening / closing lid 2 is integrated with the calculator body 1 so as to be openable / closable. As a connection structure, the calculator body 1 and the opening / closing lid 2 are integrally molded with plastic, and a crease is formed at the connection portion. The calculator main body 1 and the opening / closing lid 2 may be pin-joined to each other to open / close. Further, on the outer edge of the opening / closing lid 2, there is formed an engaging projection 2a for fixing the opening / closing lid 2 to the surface of the calculator body 1 by engaging with a recess formed in the side portion of the calculator body 1. The engaging projection 2a is pushed by the tip of the finger to open / close the opening / closing lid 2.

Further, a square opening 10 is formed in the opening / closing lid 2, and as shown in FIG. 3, a storage portion 11 is arranged at a position overlapping the opening 10 inside the opening / closing lid 2. The opening 10 may be formed in the central upper portion of the opening / closing lid 2, or may be formed on the entire surface of the opening / closing lid 2. The opening 10 is provided with an acrylic transparent plate 10a fixed with an adhesive or the like. The storage portion 11 is composed of a protrusion 2 b formed inside the opening / closing lid 2 so as to surround the opening 10 and a back lid 11 a fitted to the protrusion 2 b, and includes a transparent plate 10 a and a back lid. Sheets such as a photo sticker are held between 11a.

The protrusion 2 b may be formed in a band shape so as to surround the entire circumference of the opening 10, or a plurality of pieces may be provided at a predetermined interval. Also, after the front side of the photo sticker is placed toward the opening 10, the back cover 11 is fitted to the protrusion 2b to store the photo in the storage unit 11, and the photo is viewed from the front side of the opening / closing cover 2. You can enjoy it. Further, the operation key 4 of the calculator body 1 is provided on the back edge by forming a folded-back portion on the inner peripheral edge of the opening / closing lid 2 so as to form a predetermined depth space with the surface of the calculator body 1. It prevents contact with 11a.

A small engagement hole 12 is formed in the center of the back cover 11a, and the back cover 11a can be easily removed by inserting the tip of a mechanical pencil into the engagement hole 12 and prying it open. be able to. This makes it easy to attach and detach the lid 11a to the small back, which is difficult to handle with a fingertip.

Inside the storage unit 11, for example, a list for distinguishing a large number of key types in a modern key society from a hobby one such as a photo of a photobooth or a pet taken with oneself or a friend is practically used. Various things can be mentioned up to the typical one.

As described above, in the mini calculator according to the present embodiment, since the opening / closing lid 2 is provided with the storage portion 11 for the seals such as photographs, it is a hobby even when not used as a calculator. It can be effectively used as a source of information from practical to practical. Also, by closing the opening / closing lid 2, the surface of the calculator body 1 is protected by the opening / closing lid 2 even when the mini calculator is always worn, and the solar cell 3 or the like is damaged or the operation key 4 is removed. It will not be pushed unnecessarily.

Further, since the key holder 7 is attached, the key holder 7 can be easily attached to a pencil case, a wallet, a bag, clothes, a belt, etc., or can be stored in a pocket and always worn. Therefore, when a calculation is required, it can be used immediately, and the trouble of searching for a calculator is eliminated.

The present invention is not limited to the above-described embodiment, and the structure of the storage portion 11 is such that a slide groove is provided around the opening 10 and the restraining plate can be freely slid in the slide groove. Alternatively, a photograph or the like may be sandwiched between the holding plate and the transparent plate 10a of the opening 10. Further, the transparent plate may be crimped instead of being adhered.
