Keyboard type input device and portable information processor
First Claim
1. A key-board type input device comprising:
- an input key panel on which a plurality of key tops are integrally formed, wherein each of the key tops can be pressed down to carry out a key input;
a press-down panel for changing loads generated when each key top of the input key panel is pressed down, into a vertical load; and
a load distribution panel for distributing unnecessary loads other than the vertical load changed by the press-down panel, by deformation under a pressure;
wherein the input key panel, the press-down panel, and the load distribution panel are layered.

Abstract
A key-board type input mechanism suitable for inputting large quantity of data is provided to a portable information technology device having a pen-input type display device. A keyboard (33 or 35) of the present invention comprises a key top panel portion (12 or 17) on which a plurality of input key portions (12a or 18) that are pressed down when carrying out a key input are integrally formed, a coordinate position information generating portion (13) and contact portions (16 or 19) for changing loads generated by pressing each input key portion of the key top panel portion down into a vertical load, a load distribution portion (14 or 20) for distributing unnecessary loads other than the vertical load changed by the coordinate position information generating portion and the contact portions, by deformation under a pressure. The key top panel portion, coordinate position information generating portion, contact portion, and load distribution portion are layered.
