Abstract

PURPOSE:To eliminate uncomfortable sense likely at operating this touch button as per the present invention and enhance the printing/displaying characteristics and anti-environmetal property by forming a touch electrode of a clear insulative sheet and an electroconductive film put over the rear surface of this insulative sheet, and covering the rear side of this electroconductive film, if necessary, with another clear insulative sheet. CONSTITUTION:A touch electrode 13 is composed of a clear insulative sheet 13A, an electroconductive film 13B put over the rear surface of this sheet 13A, and another clear insulative sheet 13A' put over the rear surface of this film 13B. Accordingly the electroconductive film 13B of this touch electrode 13 is shielded perfectly from the external environment by the sheets 13A, 13A' so that there is not risk of electrostatic discharge or cooling in winter, nor involvement of uncomfortable sense in operating the button. Further because the electrode 13 consists in a plastic sheet which is transparent, it admits penetration of light to cause light emission over the whole surface of the button to provide easy-to-view characteristic for arrow marks, characters, etc. Also this is resistant to any corrosive gas in the air, solvent used in works, and the sweat to ensure that stable conductivity is maintained.

(Problem to be solved by the invention) However, in the conventional touch button, since the touch electrode i (4) is exposed on the surface, it is difficult to display arrows, floor letters, etc. formed on this by printing. In this case, arrows, floor letters, etc. disappear when touched with a finger or the like.

Therefore, from the point of view of operational functionality, floor letters, etc. formed on the surface of the touch electrode (4) must be engraved.Moreover, since touch buttons are mainly used in high-end elevators, the touch electrode (4) For this purpose, it is necessary to perform surface finishing for design purposes such as polishing, and to finish the end faces, which results in a very expensive product.

In addition, since the metal surface of the touch electrode (4) is exposed,
When a finger touches this, static electricity on the human body or the like is discharged through the touch electrode (4), causing discomfort to the fingertip. Moreover, since touch buttons are generally electronic, there is a risk that the electrostatic capacitance detection circuit and the like may be destroyed by the discharge energy, and a separate electric shock prevention circuit is required. In addition, it is possible to lay an anti-electrostatic mat on the floor to prevent the discharge of electrostatic energy as described above, but this would be very expensive and would require the person operating the touch button to stand on the mat. The discharge prevention effect cannot be achieved unless the condition is maintained.

In addition, with touch buttons that detect changes in capacitance between the elevator car and the ground for registering elevator car and hall calls, water emitted from installed objects such as water pipes and metal hoses is directly applied to the touch electrode. If this happens, there is a risk of malfunction.

Furthermore, if the touch electrode (4) is made of metal, the light emitting area is limited, and moreover, it cools down in winter, causing discomfort to the user. Discomfort, especially in winter, can be prevented by covering the touch electrode (4) with a transparent lamp, but on the other hand, covering the touch electrode (4) with a transparent cap requires increasing the detection sensitivity, and if the detection sensitivity increases, malfunctions are likely to occur. Further, due to its sensitivity, dimensional accuracy becomes strict, making such processing difficult in practice. Also, covering with a transparent cap is not desirable from a design standpoint. On the other hand, although it is possible to make the transparent cap thinner, it is difficult to mold a thin cap.
Furthermore, it is difficult to make the film thinner by insert molding, and dimensional accuracy cannot be obtained. Therefore, there is a method of pasting a thin sheet to the touch electrode (4), but the thin sheet easily peels off from the touch electrode (4), and a gap may partially occur between it and the touch electrode (4). It easily becomes unsightly.
