Abstract

(57) [Abstract] [Purpose] To solve a problem in a stylus pen used in a computer, etc., which was difficult to write due to a small frictional force (friction coefficient) between the tablet and the chip 12. [Structure] In an information input pen having a tip 2 made of a synthetic resin material attached to its tip, a small hole 6 is provided at the tip of this chip 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an information input pen (stylus pen) suitable for use as an information input device such as a computer.

[0002]

[Prior art]

 As shown in FIG. 4, a stylus pen used as an information input device for a computer or the like has a tip 12 attached to the lower end of a pen body 11 as a pen tip. By writing characters or figures by moving them, this information is taken into a computer or the like.

As shown in FIG. 4B, a pen tip or tip 12 of a conventional stylus pen of this type has a conical portion 14 formed below a cylindrical portion 13, and its tip is rounded. The tip 12 is made of synthetic resin in a non-hollow state.

[0004]

[Problems to be solved by the device]

 According to this conventional stylus pen, when the tablet 15 is made of glass in particular, the frictional force (friction coefficient) between the glass surface and the chip 12 is small, and the chip 12 easily slips on the tablet 15. There was a problem that it became difficult to write. This invention solves the above-mentioned problems by simplifying the structure.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, an information input pen having a tip 2 made of a synthetic resin material attached to the tip is formed with a small hole or a split groove at the tip of the chip 2. A small recess 6 is provided.

[0006]

A small recess 6 is formed at the tip of the tip 2, and an appropriate frictional force can be obtained particularly for a tablet made of a glass material to facilitate writing.

[0007]

【Example】

 A first embodiment of the information input pen according to the present invention will be described with reference to FIG. A tip 2 is attached to the lower end (tip) of the pen body 1 (a part of which is shown in FIG. 1), and the pen is slid while pressing the pen on a tablet (not shown in FIG. 1). This information is taken into the computer by writing letters or figures. The tip 2 as a pen tip has a conical portion 4 formed at the lower side (front side) of a cylindrical portion 3 and has a rounded tip.

In this invention, the tip of the chip 2 is provided with a small recess 6 such as a small hole or a split groove. In the first embodiment, as shown in FIG. This is the case where a small hole is provided in the rounded portion at the tip of the. FIG. 2 shows a second embodiment of the present invention, in which parts corresponding to those in FIG. 1 are designated by the same reference numerals. In this example, the small recess 6 is provided at the tip of the chip 2 with a groove having a + shape when viewed from the front (lower surface) of the chip 2.

FIG. 3 shows a third embodiment of the present invention, in which parts corresponding to those in FIG. 1 are designated by the same reference numerals. In this example, more grooves are added as the small recesses 6 than in the case of the second embodiment described above, and these grooves are extended to the boundary between the cylindrical portion 3 and the conical portion 4. is there. In any of the above cases, it was actually confirmed that the effect described above is further emphasized when the nylon fiber or the polyacetal is used as the chip 2.

[0010]

[Effect of device]

 According to this invention, since the tip is provided with a small concave portion, an appropriate frictional force can be obtained between the tip and the tablet (especially one made of glass), which makes it difficult to write in the conventional manner. There is an effect that can be avoided. For this reason, it is not necessary to make a particularly complicated structure, and a simple structure of forming a small hole or a groove is sufficient.
