Abstract:
1. A portable terminal device, comprising: a first case; a second case that is slidable along one surface of the first case; a first touch sensor that accepts input to the surface; a projecting section that projects from the second case toward the surface; a detecting section that detects a position of the projecting section; and a control section that controls input by the first touch sensor on the basis of output from the detecting section, wherein the control section enables input by the first touch sensor when the second case is in a first 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 case is out of the first position, the projecting section shifts in contact with the surface together with sliding of the second case, and the detecting section detects a position of contact of the projecting section with the surface and has a second touch sensor that accepts input by the projecting section to the surface.
