<p>The present invention discloses a signal input device capable of being rolled up, which includes: a rubber base layer, a lower circuit board, an upper circuit board and a rubber panel, from bottom to top. On the top of the rubber panel is laid plural signal input regions as required. Two films are set on the upper circuit board and the lower circuit board, respectively. On the lower film surface of the upper circuit board and the upper film surface of the lower circuit board, there are printed many conducting lines and conducting regions corresponding to the signal input regions. And between the two films, there is plurality of insulating bumps, which support the films and insulate them each other. In the signal input device according to the invention, each of conducting regions and conducting lines which is made of metal powder is printed on the circuit board. The device of the invention used in electronic organs and other toys has the very strong competitive advantage, and cost and technics for manufacturing are substantially economized. In the present invention, it does not need the higher accuracy of click, and as soon as a user clicks any point of the signal input regions, an input circuit corresponding to the point can be conducted, so the device of the invention can be used easily.</p> |
