Portable terminal device

Image Number 12 for United States Patent #8078232.

A mobile phone of the present invention includes a first cabinet; a second cabinet that is slidable along an upper surface of the first cabinet; a first touch sensor that enables input by touching the upper surface; a projection that projects from the second cabinet toward the upper surface; a second touch sensor that detects a position of contact of the projection with the upper surface; and a CPU that controls input by the first touch sensor in accordance with output from the second touch sensor. The CPU enables input by the first touch sensor when the second cabinet is in a first position (OP position) where the second case exposes a detection area of the first touch sensor to the outside, and disables input by the first touch sensor when the second cabinet is out of the first position (OP position).
