Abstract

PURPOSE: To omit the key buttons and yet realize identification for the names of keys by providing the transparent input electrodes on the light reception type display unit displaying the key names plus the insulated layer containing the through-holes at the positions corresponding to the transparent input electrodes.
CONSTITUTION: Transparent substrate 10 forming plural number of transparent electrodes 11 for key input at the positions corresponding to the input keys is laminated onto light reception type display unit 9 in which the electrodes are formed to secure the display for the names of the input keys. And then insulated layer 13 containing through-holes 12 of such size as to make electrode 11 exposed is provided on substrate 10. Thus, a contact is given via the conducting substance to the transparent electrode exposed through hole 12 to perform the input action.
