    • A collapsible data entry panel comprises, an upper layer of flexible sheet material having formed keys on its outer surface and conductive areas or contacts on its inner surface, a lower layer of flexible sheet material having conductive circuits or traces on its inner surface, and resilient, flexible frame around the peripheral margins of the sheet material layers that pulls the layers taut so that they are parallel to and spaced apart from one another. Depression of a formed key will cause a corresponding, underlying contact to connect with the conductive trace carried by the lower layer, and thereby complete a circuit representative of the depressed key. The data entry panel of the invention is collapsible to a surface area less than ½ of its extended configuration by twisting the respective ends of the panel in opposite directions, while applying a slight inward pressure. In its collapsed configuration, the panel can readily fit into a shirt pocket or purse. If the panel is subsequently released, it will automatically spring back to its original, extended configuration.
    • 可折叠数据输入面板包括:在其外表面上具有形成的键的柔性片材的上层和其内表面上的导电区域或接触件,在其内表面上具有导电电路或迹线的柔性片材的下层,以及弹性 围绕片材材料层的周边边缘的柔性框架,其拉紧层,使得它们彼此平行并间隔开。 形成的键的凹陷将导致相应的底层接触件与由下层承载的导电迹线连接,从而完成代表按下的键的电路。 本发明的数据输入面板通过在施加轻微向内的压力的同时在相反的方向上扭转面板的各个端部而可折叠到小于其延伸构造的1/2的表面积。 在其折叠的配置中,面板可以容易地装入衬衫口袋或钱包。 如果面板随后被释放,它将自动弹回到原来的扩展配置。
