重ねた構造になっている。2. Description of the Related Art A conventional pressure-sensitive input panel has a transparent conductive film 3 (hereinafter abbreviated as "conductive film") laminated on a lower glass substrate 5, as shown in FIG. It has a structure in which an upper substrate made of a transparent flexible insulating sheet 4 having a transparent conductive film 2 is overlaid on spacers 1 dispersedly arranged on a conductive film 3.

By detecting, the position coordinates at the contact position 8 are obtained. The principle of detecting the coordinate position is described in Japanese Patent Application No. 4-150935 previously proposed by the applicant of the present invention.

ードに代わる入力装置として広く用いられている。As described above, since the pressure-sensitive input panel only needs to have the insulating spacer 1 interposed between the upper and lower conductive films 2 and 3, it can be constructed without patterning the conductive film. Costs can be reduced. Further, since it has a characteristic that it can be input with a stylus pen and a finger, it is widely used as an input device replacing a keyboard.

さＨが高すぎると、スタイラスペン７を強力な力で押し
つけないと、上下の導電膜２、３が接触できない。However, in the pressure-sensitive input panel having the above-described structure, if the distance L between the spacers 1 is too small or the height H of the spacers 1 is too high as shown in FIG. Unless the stylus pen 7 is pressed with a strong force, the upper and lower conductive films 2 and 3 cannot contact each other.

入力が発生するといった恐れがある。On the contrary, as shown in FIG. 7B , if the distance L between the spacers 1 is too large or the height H of the spacers 1 is too small, the upper and lower conductive films 2 and 3 come into contact with a small force. ,
Even if the hand holding the stylus pen 7 is simply placed on the upper substrate, the conductive films 2 and 3 come into contact with each other. Therefore, the places where the pressurization is not desired are often inadvertently brought into contact with the pressurization, and there is a possibility that erroneous input may occur.

誤入力が発生し、信頼性に欠けたものとなる。As described above, if the arrangement conditions such as the spacing and height of the spacers 1 are not appropriate, a large input load is required,
A strong writing pressure is required at the time of input, and the upper substrate is easily damaged, leading to a shortened life. Conversely, in the case of a structure in which the upper and lower conductive films 2 and 3 are in contact even with a small input load,
An erroneous input occurs, resulting in lack of reliability.

切なスペーサ配置条件を設定する必要がある。Accordingly, in a pressure-sensitive input panel,
One of the factors that plays a large role in the simplicity and reliability of input and the selection of the input means is the spacer, and the arrangement conditions such as the width, height, and spacing of the spacer are higher when input is performed with a stylus pen or the like. Since it greatly affects the amount of deflection of the substrate, it is necessary to set appropriate spacer arrangement conditions in designing and manufacturing a pressure-sensitive input panel having an excellent user interface.

Difficult to obtain.

However, only the relationship between the spacer arrangement conditions and the radius of curvature of the tip of the input means is examined. Since no consideration is given to the input load as described above, FIG.

Pen input load was measured for a prototype pressure-sensitive input panel differing only in the height of the spacer. As a result, the pen input load P gradually increases as the spacer height H increases. Based on such experimental results, a relational expression between a spacer arrangement condition and a pen input load was approximated.

For the pressure-sensitive input panel with only the spacer height changed, the relationship between the spacer height and the pen input load is shown. The result also shows that the evaluation coefficient β is 0.04 ≦ β ≦ 0.8.

mmの範囲が最適である。In this experiment, a pen made of polyacetal resin was used, but the radius of curvature of the tip of the input device was 2 mm.
In the above case, the tip is too thick and it is difficult to know where the user is pushing. On the other hand, if the radius of curvature of the tip is 0.5 mm or less, the tip may be too sharp and may scratch the upper substrate 4. Therefore, the radius of curvature of the tip of the input pen is 0.5 mm to 2.0 mm.
The range of mm is optimal.
