られる。Various types of coordinate input devices of this kind are known, such as tablets, digitizers, touch panels, etc. These devices generally have conductive sheets placed facing each other on both sides of a frame-like Nupaca, and are designed to detect the coordinate position of the suppressing contact point of the two conductive sheets. In this method, a pair of conductive sheets placed opposite each other are separated by a predetermined distance through a frame-shaped Nupaca having a uniform thickness, and are compressed and deformed with an electric pen, finger, pencil, etc., and then brought into point contact and electrically connected. Since the coordinates are converted into coordinates and input into the computer, at least the conductive sheet on the operation side must have moderate visibility, usually 50 μm or more.
A visible conductive sheet is used, in which a thin film of about 300 μm thick visible resin film such as polyethylene terephthalate is coated with a thin film resistor made of indium/tin oxide or the like of about several hundred amperes.

の点でも接触する等、異常動作を生じる欠点があった。However, it is difficult to stretch such a thin combustible conductive sheet onto a frame-like spacer so that the distance between the two sheets is uniform, and even if it is stretched, the conductive sheet will not be properly stretched during use. This has the drawback of causing abnormal operation, such as the central part being stretched and always being turned on, and especially in the case of a touch input panel with a large input surface, contact may occur at points other than the input point.

バネルの製作が困難なものであった。For this reason, it has been proposed to seal insulating oil between both grooved conductive sheets, but this causes problems such as uneven application of pressing force and two-point contact. In addition, the tip of the fine dont between these two sheets may buckle due to compression, or
The operating surface is large because the conductive thin film in contact with the tip part may break and peel due to friction, or the number of times of cutting may be low due to the conductive thin film breaking due to repeated bending in the surrounding area. It was difficult to produce a touch panel.

This provides a touch panel.

。That is, the present invention consists of a polyvinylidene fluoride piezoelectric film arranged between two grooved conductive sheets on which a transparent conductive thin film made of indium tin oxide is deposited on at least one side, eliminating the space. Since the position of the pressing point can be detected, the conductive layer of the conductive training sheet prevents the resistance layer from breaking due to two-point contact, poor contact, or repeated bending. Shaping operations such as outward bending and solidification, which can form a large input surface, can also be performed relatively easily.
ホリ弗化ビニリデンは極めて加工性に富んだ０ 熱可塑性樹脂であるので容易に数μ乃至数−μ。Polyvinylidene fluoride is highly processable. Since it is a thermoplastic resin, it can easily be several microns to several -microns.

は極めて僅かの接圧で敏感に作用することができる。A thin and strong film can be obtained, and the area can be any size. Furthermore, if this film is heat-treated under a high-voltage electric field, it will exhibit extremely high piezoelectricity that cannot be obtained with other organic polymers. Therefore, the input device of the present invention using a piezoelectric polyvinylidene fluoride sheet can act sensitively with extremely small contact pressure.

用出来る。Vinylidene fluoride-based resins include vinylidene fluoride monopolymers, copolymers containing vinylidene fluoride and copolymerizable monomers, and others mainly composed of these polymers or copolymers. Polymer blends with high molecular weight polymers, etc. can be used.

かかる懸念は極めて少い。A touch cover panel using vinylidene fluoride resin is also described in Japanese Patent Publication No. 51-49369, but this is made by covering electrodes on both sides of a vinylidene fluoride resin sheet, and since the electrodes are pressed directly, it is quite durable. Electrodes must be deposited, and those that are coated with a transparent conductive thin film of indium/tin oxide have extremely low durability and are not practical, but in the present invention, a transparent conductive thin film of indium/tin oxide is deposited. Since the film (for example, polyethylene terephthalate) is laminated with the vapor-deposited side facing the vinylidene fluoride resin side, such concerns are extremely low.

し接触がなく極めて有利である。In addition, as mentioned earlier, in the case of the conventional conductive film in which there is a space between the conductive films, a large number of 7-pacers are arranged in the form of dots, so when pressing, the blind spots are created by the nu-pacers, and the contact points of the conductive film in both grooves. The contact area is limited and the conductive layer in that area is subject to a lot of wear and tear, but with the device of the present invention, there is no blind spot due to the Nupacer and the entire area of the film is usable area, so there is less wear and tear on the conductive layer. By interposing the vinylidene fluoride resin film, the pressing force is dispersed and there is no repeated local contact, which is extremely advantageous.
