PURPOSE:To prevent a pressure domain from being formed at a liquid-crystal display part during key input by interposing liquid between a transparent keyboard part and the liquid-crystal display part. CONSTITUTION:The 1st transparent sheet 1 is pressed at a specific position C from above so as to input optional key contents, and then the sheet 1 flexes to allow the 2nd transparent sheet 2 to flex as well. For the purpose, the elastic transparent liquid 7 is injected between the transparent keyboard part A and liquid-crystal display part B so as to prevent the pressure from being transmitted to the liquid-crystal display device 4. Consequently, the flexure of the sheet 2 is dispersed and absorbed by the liquid 7 as external force to stop or reduce greatly the pressure to the liquid-crystal display device 4. For the liquid 7, such liquid is used as water or transparent liquid having viscosity and elasticity, and a rectangular frame body 8 is interposed between the keyboard part A and liquid-crystal display part B to inject the liquid 7 into it. |
