<p>PURPOSE:To obtain a small-sized input device which has good operativity and allows plural input means to be easily selected without replacing any connector by providing a pen tough input means different from a keying keyboard input means to the reverse surface of the input device opposite the keyboard input means. CONSTITUTION:Tri-state output buffers 10a and 10b output electric signals from a keying type keyboard input contact part 8 and a membrane type pen touch input contact part 9 to a driving circuit 11 according to the identification signal of an input means from a changeover switch 4. Namely, when the changeover switch 4 is off, the tri-state output buffers 10a and 10b are on and off respectively and input data 12 is input information from the keying keyboard input contact part 8. When the changeover switch 4 is off, on the other hand, the input data 12 is input information from the membrane type pen touch input contact part 9.</p> |
