Abstract

(57) [Summary] [Purpose] To improve the operability of the input pen and enable accurate input of information. [Structure] For example, mortar-shaped concave grooves 21 are regularly arranged on the surface of a locus detection sheet 12 according to input information. When there are many straight lines in the information, the concave grooves 21 are arranged in a mesh pattern, for example, and when there are many curved lines, the concave grooves 21 are arranged without any gap.
The input pen 13 is stably arranged in the concave groove 21, and resistance is generated when the input pen 13 is pulled out from this and moves to the adjacent concave groove 21. This serves as a frictional force and gives a feeling of writing on paper, which improves the operability of the input pen 13. Also,
Since the moving direction of the input pen 13 is regulated according to the information, the information can be accurately input.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pen touch information input device capable of improving operability.

[0002]

2. Description of the Related Art Recently, pen touch information input devices are increasing as information input means of computers. As is well known, when the display pen such as a liquid crystal is moved with the input pen in contact with the display, the locus is input as information. For example, if you write the letter A with the input pen,
This is directly input as A. Then, the letter A is displayed on the display.

[0003]

By the way, in the conventional pen touch information input device, a locus detection sheet formed of glass, plastic, vinyl or the like is pasted on the screen of the display, and tracing is performed with the input pen. It is usually like this. Since the surface of such a locus detection sheet is slippery, it is difficult to move the input pen in a desired locus, and there is a problem that operability is poor.

For example, as shown in FIG. 7, a display 1
When writing a character on 1, the line bends in the middle, or when the movement of the input pen 13 is stopped at a certain point, the input pen 13 slips and the line extends to an unnecessary position. There are many. Therefore, characters and figures may be distorted and input, and in some cases incorrect information may be input.

Therefore, the present invention solves the above-mentioned problems, and proposes a pen touch information input device in which the operability of the input pen is good and information can be accurately input. .

[0006]

In order to solve the above-mentioned problems, in the present invention, the locus of the input pen is changed by moving the locus detection sheet attached on the display while the input pen is in contact with the sheet. In a pen touch information input device capable of inputting corresponding information, in order to make it easy to move the input pen in a predetermined direction, a regular unevenness according to the input information is provided on the trajectory detection sheet. It is what

[0007]

As shown in FIG. 1, the locus detection sheet 12 is attached on the display 11, and as shown in FIG. 2A, for example, a mortar-shaped concave groove 21 is formed on the surface according to the input information. Are regularly arranged. When there are many straight lines in the information, the concave grooves 21 are arranged, for example, in a grid pattern as shown in FIG. 7B, or when there are many curved lines, the concave grooves 21 are arranged without gaps as shown in FIG. .

The input pen 13 is stably arranged in the concave groove 21, and resistance is generated when the input pen 13 is extracted from the concave groove 21 and moves to the adjacent concave groove 21. This serves as a frictional force and gives a feeling of writing on paper, which improves the operability of the input pen 13. Further, since the moving direction of the input pen 13 is regulated according to the input information, it is possible to suppress the variation of the locus of the input pen 13 and input the information accurately.

Further, as shown in FIG. 4, when the linear concave groove 26 having a rectangular cross section is provided, it becomes easy to input a figure having many straight lines. Further, even if the convex portion 27 is provided as shown in FIG. 5, the same operation and effect as described above can be achieved.

[0010]

Embodiments of the pen touch information input device according to the present invention will now be described in detail with reference to the drawings.

FIG. 1 shows the configuration of a pen touch information input device 1 according to the present invention. This pen touch information input device 1
A locus detection sheet 12 is attached to a display 11 such as a liquid crystal display. The locus detecting sheet 12 is similar to the general locus detecting sheet 12 in the input pen 1.
When 3 is contacted and moved, the locus is detected. The detected locus of the input pen 13 is input to the microcomputer 14 and its shape is analyzed, and this is recognized as information. The information recognized here is the display 1
1 and is displayed at the same place as the locus of the input pen 13. The information recognized by the microcomputer 14 can be output from an output terminal 15 to an external computer or the like.

The locus detecting sheet 12 is formed of, for example, transparent glass, plastic, vinyl, or the like, and as shown in FIG. A bowl-shaped groove 21 is provided. The size and depth of the groove 21 can be set according to the size of the tip of the input pen 13 and the resolution of the locus detection sensor built in the locus detection sheet 12. In this example, the concave groove 21 is set so that the tip of the input pen 13 slightly enters, and the periphery thereof is rounded so that the input pen 13 can easily move.

When the input pen 13 is lightly pressed against the locus detection sheet 12, the input pen 13 is stably placed in the concave groove 21. When the input pen 13 is moved, it is guided from the concave groove 21 to the center of another concave groove 21. That is, the moving direction of the input pen 13 is regulated. Then, when the input pen 13 is moved out of the groove 21, a certain amount of resistance, that is, frictional force is generated,
You get the feel of writing letters on paper. As a result, the operability of the input pen 13 is improved, and the input pen 13 can be moved according to the character or figure intended by the operator. That is, it is possible to prevent distortion of input characters and figures.

The concave grooves 21 are, for example, circular as shown in FIG. 1B, and by regularly arranging the concave grooves 21 in accordance with the information input by the input pen 13,
It becomes possible to regulate the movement of the user and input the information accurately. In this example, the concave grooves 21 are arranged in a line in the vertical and horizontal directions at appropriate intervals. In this arrangement, horizontal lines 22, diagonal lines 23, and vertical lines 24 are easy to write as indicated by arrows in the figure. FIG. 3 shows a case where the concave grooves 21 are arranged without a gap, and this arrangement is suitable for writing the curve 25.

Further, instead of the mortar-shaped concave groove 21, FIG.
It is also possible to provide a linear groove 26 having a rectangular cross section as shown in FIG. This groove 26 is shown in FIG.
It is possible to arrange them in a grid pattern as shown in
This case is suitable for inputting many straight lines such as drawings.

Further, as shown in FIG. 5, instead of the concave grooves 21 and 26, for example, by regularly arranging the dome-shaped or arcuate cross-section linear convex portions 27, the same action and effect as described above can be obtained. It is also possible to achieve

In the above-described pen touch information input device 1, the operability of the input pen 13 is improved, and the moving direction of the input pen 13 is restricted according to the input information. Therefore, as shown in FIG. Variations are suppressed and it becomes possible to input character information quickly and accurately. Therefore, even when applied as an input unit of a computer or the like, it is possible to eliminate erroneous recognition of information.

[0018]

As described above, according to the present invention, in order to facilitate the movement of the input pen in the predetermined direction, the trajectory detecting sheet is provided with the regular unevenness according to the input information. Therefore, according to the present invention, when the input pen is moved in contact with the locus detection sheet, an appropriate frictional force is generated, so that a feel like writing on paper is obtained and the operability of the input pen is improved. . In addition, since the moving direction of the input pen is regulated by the regular unevenness according to the input information, it becomes possible to input information accurately, and even when used as an input section of a computer, erroneous input of information can be prevented. It has the effect of being preventable.
