[Problem to be solved by the invention]

A book-type, notebook-type Japanese word processor.

Personal computers have built-in batteries so that they can be used easily on trains or anywhere. In addition, external storage devices such as floppy disk drives and LCD backlights are becoming essential for Japanese word processors and personal computers, so the batteries built into Japanese word processors and personal computers can usually only be used for a few hours. This is the current situation. Furthermore, if a battery with a power supply capacity that can be used for a long period of time is used, a problem arises in that the volume and weight increase, making it inconvenient to carry.

The object of the present invention is to make a lightweight battery such as a sealed lead battery into a form that can be inserted into a memory card slot so that it can be used for both power supply and memory card insertion, thereby reducing the volume and weight of the personal computer itself. In addition, the usage time can be extended by using the battery inserted through the memory card slot together with the battery built into the Japanese word processor or personal computer, or by having the user carry a battery that can be inserted through the memory card slot. be able to.

[Means to solve the problem]

In order to achieve this objective, in the present invention, a battery that can be made thin, such as a sealed lead-acid battery, can be inserted into a memory card slot, and an insertion slot that can be used for both power supply and memory card insertion is provided. .

[Effect]

A battery that can be made thin like a sealed lead-acid battery can be inserted into a memory card slot and serves both as a power supply and memory card insertion, making the Japanese word processor and personal computer itself smaller and lighter. To extend the usage time by using the battery inserted through the memory card slot together with the battery built into the Japanese word processor or personal computer, or by having the user carry a battery that can be inserted through the memory card slot. I can do it.
