Abstract

PURPOSE:To prevent a part other than an effective input area simply from misinput and to make the mounting structure of a protection cover easy by covering the part other than the effective input area completely with an insulating member. CONSTITUTION:The insulating member 4 is arranged like dots on the whole effective input area on the surface 2a of a substrate and also arranged on its periphery so as to cover the whole electrode surface 2a other than the effective area like a band. Therefore, electrodes 1a, 1b are not connected at the part other than the effective input area which is covered with the insulating member 4, so that no input is performed even if the part is depressed with a writing tool. Consequently, misinput can be simply prevented. Since the part other than the effective area on the electrode surface 2a is converted with the insulating member 4, the protection cover 3 can be directly brought into contact with a flexible sheet 1. Thus, the mounting structure of the protection cover can be simplified.

Description

[Detailed Description of the Invention] [Technical Field of the Invention J] The present invention relates to the invention where characters written on paper on an input panel have shapes or shapes written on the surface of the input panel manually. Learned through oppression.

The technical background of this device is that the opposite electrodes trace each other under the pressure of the machine. Is it due to sudden changes in time? However, it is essential to maintain an insulated state except during suppression. Methods for maintaining this insulating state have been studied and realized many times, including a method of arranging an insulator between opposing electrodes.

Figure 1 shows the structure of the C blade surface, and Figure 1 is a partial sectional view of the water input board. Figure 2 shows the small parts. In other words, the distance between the electrode surfaces 1a and 2a is maintained constant by arranging the insulating member 4 in a grid pattern or in a dot pattern on the entire surface of the electrode surface 2a, with a portion of the electrode surface 2a protruding T. It was ℃.

[Basic score on background technology]

The problem with this device is firstly the problem of erroneous input. In the conventional clamping, the same structure is used over the entire 2μ surface of the substrate, that is, the safe is the electrode surface, and its size is the area that can be obtained, that is, the area surrounded by the protective cover 3,
The leek was also thick. As for the reason, first of all, what about the whole thing? The a-pole is 5 partially 111. This is because it is cheaper to manufacture than arranging electrodes.The size of the electrode surface is now the same size as the effective human power vlt area of the board 2.The effective input area here is This refers to an effective input area that can be output as position coordinates to the outside.Hereinafter, this is simply referred to as an effective input area.5oIf we assume the above, the position of the protective cover 3 can be in the following 2a, and the first As a result, place it just outside the input area.

Board 2 and that? This can be done by the solid board 5. The flexible sheet 1 may be torn at right angles at the 44th step portion of the substrate 2, and the electrode 1a may be damaged. Secondly, when the protective cover 3 is positioned so that it will not bend due to the storage cover 3, and the effective human power is moved away from the castle, the above-mentioned level difference will exist in the area of the input port, and the writing instrument Alternatively, due to the suppression by the manual pen, it is thought that 100 million la of damage was caused to the above step part in the same way as in the first case.

To prevent hot water loss in base & 20 size building 1a.

The reason was that it was made larger than the area that could be entered.
Furthermore, on the other side of the flexible sheet l, there is a peripheral edge #lL and other features (not shown) around the resistance layer for connecting with the outside.
ff, it is formed in an area larger than the effective human power area.

CI: What is the resistance layer? 5F flexible sheet 1's Wt surface a is larger than 0, so the electrode surfaces 1a and 2a cannot be larger than the effective input area. Is there a part with the same structure as the inner R part outside the valid input area? Pressing the button may cause incorrect input. Is that why you entered it incorrectly? In order to prevent, what is the effect of human power area r town flexible sheet l si memory surface bKHi note 'Ik,? However, it is clear that this method is not definitive for preventing erroneous human input. In addition, due to stock acquisition cover 3, ■ outside the area of effective human power? It is conceivable to cover it, but in this case alignment will be difficult.

The second issue is the problem regarding the protective cover 3 located at the peripheral edge of the ωj recorder sheet l and the base &2. For some reason, it is preferable to be in contact with them. However, even in the case of the same contact/), there are two methods for flexible seams (1): one in which no pressure is applied during installation, and the other in which pressure is applied and contact is made. Because of this, the traditional method of naming mosquitoes was used. However, in the latter case, the problem of short circuit may occur.
When the part to which pressure is applied due to the housing of the housing cup 3 is smaller than the arrangement interval of the insulating member 4 on the electrode 1ILlza, a short circuit may occur between the gt poles 1a and 23 due to the pressure.
Even if the spacing is thicker than the Ail interval, the
Similarly, due to the unevenness of 1II114 that fits into the shape that you can't live without
In addition, problems have arisen in manufacturing where it is necessary to smooth out unevenness in the parts where the output changes.

In the third interval, there is a short circuit caused by the plug 1c of the servant 1a. Conventionally, in order to make effective use of the rear surface 5a (T+ space) of the board 5, coordinate detection boards, etc. were mounted on the rear surface 5a (C) of the board 5.
- A plug 1c for connecting the electrode surface 1a of the board 1 and the FfIJi board 1c is made in the board 5 by taking advantage of its flexibility and an L hole is provided, thereby making the back 11115 a %l.
Let's curve it to L and make it legal. Therefore, due to bending, the end faces of poles 1a and 1002a are in contact and short-circuited due to the wire breakage. Therefore, with the conventional device,
Insulating film on base & 20 peripheral edges? Is there a method for attaching a flexible sheet to prevent short circuits? Hentai Seza/b? 0 [Purpose of invention] Does this invention have any drawbacks? In addition, it is possible to prevent erroneous input in areas other than the effective human power area, and the mounting structure of the protective cover placed around the id surface and the temporary mounting practice of the human power detection crystal are also provided to each person. [Summary of the Invention] This invention provides a pressure-sensitive tablet input device 7a' for the purpose of providing a pressure-sensitive tablet input device 7a' for the entire purpose.

The figure shows a flexible plastic film with a thickness of 2 μm and 00 to 150 μm. As a base material, a 2-a-K insulating layer is laminated on its surface.

Furthermore, the absolute Rg member 4 is arranged on top of it.This is arranged in the same shape in the form of points and valleys over the entire effective manpower area at equal intervals so that a part of the other surface 2a is exposed. Even if it is as simple as that, the electrode I of the entire effective human power area can be placed around it.
The whole of jo2a? It is placed in a conventional manner so as to cover it. The above-mentioned grooved connector base @ 2 is connected to the entire board 5 of the same size using a two-way adhesive tag, etc. However, the above 4-increase has been extended to 7.

A plastic film with a thickness of 9,100 to 150 μm was used, and a six-track process was started on the front side to make it possible to write on it and to improve its durability. On the other side, there is μ in song 1a.

The resistance layer (1) has a chain plate thicker than the VC range.

At this moment, electrodes la and 2a
is between the pair, so when the sheet 1b is pushed out, the electrodes 1a and 2a trace due to the bending of the sheet.The electrical change at this time causes the pressing point to be Figure out the position of T...The part other than the self-effecting human power coffin which is behind by the insulating member 4 from the above-mentioned ridge hook is H, +L [because 1a and 28 are not traced.

It is clear that even if you press 6C and 6C, you will not input it. 1 castle is stipulated in the middle of the day as the person who has no clothes and no seki surrender, and it is easy to settle the area with the protection cover 3, which is difficult to implement, and there is no need for it. Although the protective cover 3 is placed on top of the burnable sheet 1, the portion other than the part on the tunic (2) 2a is restored to the insulating member 4.

The protective cover 3 can be fitted onto the Kaorimachi baking process sheet L without worrying about short circuits, and can be installed without having to pay attention to the shape constraints or manufacturing problems of the pressure application/b part. The shape and mounting structure of the cover 3 can be adjusted.
