Description

The present invention relates to brush Kigu.

Currently, various electronic devices that can be operated by directly touching the surface of a liquid crystal panel are provided. Such a liquid crystal panel is called a touch panel.
There are various touch panel principles. For example, there is a so-called pressure-sensitive type that senses pressure applied to the surface of a liquid crystal panel. During this method, as need not directly touch the liquid crystal panel surface, it is possible to use a tool called a so-called touch pen. Although such touch pen typically has an axis and a tip of the writing instrument-like, in order to prevent damage to the liquid crystal panel, Ru der those formed by rounding the tip relatively soft material such as plastic.

  By the way, the writing tip of a writing instrument having a use for writing on paper has a structure in which ink or the like oozes out, or a pointed core protrudes. Therefore, it cannot be said that the writing tip of the writing instrument is suitable for use as a touch pen because the touch panel may be soiled by ink or the like or may be damaged by a sharp tip. That is, the writing instrument and the touch pen need to be formed as completely separate structures. However, since there are many occasions where touch panel electronic devices are used at the same time while writing with a writing instrument, there is a desire to improve convenience by providing a writing instrument, a ballpoint pen and a touch pen on the same axis. Certainly exists.

  Therefore, a technique combining a touch pen and a ballpoint pen is disclosed in the following patent documents.
