にドツトスペーサ３を印刷し絶縁を保っている。Structure of a conventional example and its problems A conventional example of a position detection device having an input surface using two resistance plates is shown in FIGS. 1 and 3. Figure 1 shows 1A electrode on both ends.
, two resistance plates 1, 2 provided with 1B, 2A, 2B
A dot spacer 3 is printed on the top to maintain insulation.

導通不可能であり不感点となって位置検出ができなかっ
た。When characters or figures are written on one of the resistor plates 1 and 2, the double-folded resistor plates 1 and 2 are electrically conductive at the point where the writing instrument is applied. This is a configuration for detecting coordinates. The dot spacer 3 is made by printing insulating paste in a dot shape. However, as shown in FIG. 2, if the dot spacer 3 is made thicker in order to secure the gap between the resistor plates 1 and 2, the dot spacer 3 will inevitably become larger than the resistor plates 1-! The area of the dot relative to the dot 2 is small, and when characters are written on the input surface, the double-folded plates 1 and 2 cannot be electrically conductive in the area where the dot is located, and the position becomes a dead point, making it impossible to detect the position. There wasn't.

。In order to reduce dead points, the pitch of Tonotos 3-Sa 3 may be increased, frame-shaped spacers may be used on the sides of resistance plates 1 and 2, and gas or liquid may be injected between the resistance plates 1 and 2. When it is filled, the side of the little finger side of the hand is placed on the input surface when writing, resulting in erroneous inputs on that part, and in some cases, inputting by simply placing the ruler.

力できる点は筆記具による図形入力面と指先によるコマ
ンド入力面を共用できる長所であった。When finger input is used for command input, and a drawing input surface using a writing instrument and a command input surface are configured on one input surface, there is a difference between + and [, which increases the input area. This can be solved by sharing some parts. Therefore, the command input screen must also be able to input graphics. In the case of the Dot Spacer 3, handwritten characters and figures can be entered with a pencil or ballpoint pen, and in addition, input can be made with a fingertip, which is an advantage of being able to share the figure input surface with a writing instrument and the command input surface with a fingertip.

よって不感点の問題は解決できる。FIG. 3 shows a conventional example in which a pressure-sensitive conductive rubber patch 4 is used instead of a dot spacer. The Pressure-Sensitive Conductive Rubber Notebook 4 has been developed so that even if the side of the hand is placed on the input surface during writing, that part will not be input, and only characters and figures written with a pencil or ballpoint pen can be input. By using it, the problem of blind spots can be solved.

線上で図形入力すると不連続となる欠点があった。If a pressure-sensitive conductive rubber notebook 4 is used, which conducts when pressure is applied with a finger, input can be performed even by pressure with a finger. However, when using the pressure-sensitive conductive rubber notebook 4, the fingertips
Two types of pressure-sensitive conductive rubber sheets 4 suitable for inputting each writing instrument are prepared and placed adjacent to each other, and there is a drawback that inputting a figure on the boundary line results in discontinuity.

て指先でも入力不可能である。FIG. 6 is a sectional view showing an example of applying pressure by the side surface of the hand. In FIG. 5, the tip of the ballpoint pen 8 is a ball with a diameter of o, smm. Assuming that the pressurized area is a cylinder with a diameter of 0.6 mm, its area SB is as follows: 5B=(0,5/2)Xπ o,2(ma). Assuming that the writing pressure required for electrical connection between the resistor rubber notebook 5 and the resistance plate 7 by applying pressure with the tip of the ballpoint pen 8 is E501, the writing pressure P per unit area required for electrical continuity is P = 5010.2 2-2tso (/mj). When applying pressure from the side of the hand, if we take a value of 1000 (ma) as an example of the pressure area, the pressure PH at which the input surface becomes conductive is PH = P x 1000 = 250000 (g) = 250 (Kp). be. Therefore, it can be seen that the input surface does not conduct during normal writing operations. If the pressure is still applied at the pad of the fingertip, taking a value of 8o (mλ) as an example of the pressurizing area, the pressure PF at which the input surface becomes conductive is PF - P × 80 = = 2oooo (g) = 20 (2). Therefore, it is impossible to input with a fingertip.

の部分での加圧の４分の１となり約５Ｋｐで導通する。FIG. 7 is a cross-sectional view of the area A in FIG. 4 where pressure is applied with the fingertip 11, which is the input area by the fingertip. Here, there is no weft, only warp 6A. Since the weft is eliminated, the gap between the resistor rubber sheet 5 and the resistor plate 7 is halved, and the area supporting the resistor comb sheet 5 is also halved, so the pressure applied by the fingertips 11 at this time is applied to the region B. This is one-fourth of the pressure applied at , and conduction occurs at approximately 5Kp.
さらに加圧を少なくするため、縦糸６Ａを１０本に１本
ないし２０本に１本になるよう、間引くことにより導通
に必要な力は２５０〜５００．９になる。Furthermore, in order to reduce the pressure, the force required for conduction becomes 250 to 500.9 by thinning out the warp yarns 6A to one in ten to one in 20.
構造から明らかにＢの領域は筆記具によっても入力可能
で入力面Ａ、Ｂの境界で不連続にはならない。It is clear from the structure that the area B can be input using a writing instrument, and there is no discontinuity at the boundary between the input surfaces A and B.

A constant current power source 19 is connected to the lead wires 5a and 5b of the equivalent circuit 18 in which the two resistors on the input surface are electrically connected through resistors 12 and 13, respectively. The lead wires 7a and 7b constitute a current feedback circuit to the constant current power supply 19 via the resistors 14 and 16.゛The detection circuit 16 is connected to the electrode 5A of the resistor rubber sheet 5.

If the resistance value up to 8A is r(,), and the resistance value between the electrodes 5A and sB of the resistor rubber sheet 5 is R, then the resistance between the electrode 5A and the conduction point 18A and the resistance between the electrode 5B and the conduction point 18A are 12.13 is a bridge circuit. In this case, if the resistance values of the resistors 12 and 13 are r, the potential difference between the electrodes 5A and 5B is expressed by the following equation. If the potential difference is ■, then vx=

Therefore, it is possible to detect the position written by the writing instrument, that is, the position in the X direction of the point of conduction between the resistor rubber sheet 5 and the resistor plate 7. The gain of the detection circuit 16 is set to 0.

When the resistor rubber sheet 6 and the resistor plate 7 are electrically connected due to the writing operation, a current I flows from the constant current power source 19, which causes a voltage drop across the resistor 21, and the presence or absence of the writing operation is determined by that voltage.

用性に富み、きわめて有利なものである。Although the effects of the invention have been described in detail based on one embodiment, it is clear that a position detection device having only an input surface using a writing instrument or a position detection device having only an input surface using a fingertip can be constructed. Further, the pressure required for input can be selected depending on the thickness and rubber hardness of the resistor rubber sheet, and the thread diameter and pitch of the insulating woven fabric. By using a resistor rubber sheet as the resistance plate in the example, it has the effect of lowering the pressure required for input, and by adding a flexible sheet to the input surface, the degree of flexibility reduces the pressure required for input. It is also possible to select the pressure. In this way, it is possible to select various pressure forces, and as long as the difference in pressure force is within the range of the insulating woven fabric, input parts with different pressure forces can be placed on the same plane without creating discontinuities. What can be done is highly applicable and extremely advantageous.
