Abstract

PURPOSE:To obtain an electronic calculator excellent in portability and feeling of use by constituting the outside of an electronic calculator mainly of soft inner and outer sheet materials and a flexible base plate and making the body thin. CONSTITUTION:A film base plate 14 is inserted between an outer cover 1 and an inner cover 2. Calculation is performed by pressing a key cover sheet 13 through the sheet 13 in a lower cover part 4 of the base plate 14. When carrying, the sheet 13 and a display part 7 are folded inward making the hinge part 5 a boundary. The lower cover part 4 and the hinge part 5 are made of flexible material. Though a panel 6, a display part 7 and a radiowave part 8 in an upper cover part 3 are hard, they are connected by flexible film connectors 12. As the outer cover 1 and the inner cover 2 are also flexible, the calculator is highly pliable as a whole.

In Fig. 41, a indicates the product body, b indicates a notebook type case for storing the product, and C indicates a vinyl belt for attaching the product to the notebook case. According to the above configuration, it is common for the product body A and a notebook-type case B to protect it to be included (1). In the conventional example, the product body a and the notebook-type case b are separate, so there is a disadvantage that the thickness increases when they are attached.In addition, the product body a may be damaged due to the hassle of attaching it or the application of a certain amount of vibration or shock after attachment. There was a drawback that the product could come off the notebook type case b.Furthermore, since the product body a was made of plastic or a hard material such as money, it was necessary to take care not to apply excessive force to the product body when carrying it.Also. Since the material that constitutes the main body of the product is the hard material, the image given to the user by the user is that it tends to be cold and hard, which has the disadvantage of being difficult to extract from it1. OBJECTS OF THE INVENTION The present invention eliminates the disadvantages of tenn121IYX and improves portability,
