ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to an improved pushbutton-input device, particularly to a pushbutton-input device foldable along cutting lines for reducing volume and enhancing portability thereof.
Following to maturity of the personal communication science, application of the mobile phone, the public domain account (PDA), etc have been extended to the scope of the Internet transmission already, and one of the major appeals until now is emphasizing in portability and appearance that urges designers to care about volume and weight of abovesaid products.
Taking the pushbutton-input device for example, some of the existing keyboards with relatively smaller pushbuttons do not conform to human body mechanism for operation, others with larger pushbuttons are awkward in portability, and it seems that the defects always accompany the merits.
SUMMARY OF THE INVENTION
The primary object of this invention is to provide an improved foldable pushbutton-input device portable and conformable to human body mechanism, wherein a plurality of assembly-jointing sections is defined by properly spaced predetermined positions of pushbuttons on a baseboard, and a plurality of pushbuttons and a circuit board made of a flexible material are assembled on the assemblyjointing sections, so that the pushbutton-input device can be folded along a plurality of cutting lines for reducing its volume.
Another object of this invention is to predetermine a binding area in the baseboard for combining the assembly-jointing sections with a signal-output circuit section in order to avail positioning the former.
A further object of this invention is to dispose a positioning sheet made of a flexible Polyester material on the bottom face of the baseboard to serve as an auxiliary measure for positioning the assembly-jointing sections.
