Abstract:
A portable information processor comprising:first and second portions superposable in stacked form relative to each other; a deformable member connecting said first and second portions so as to allow said first and second portions to be superposed in said stacked form; a light-emitting device and a photodetector provided in said second portion; a light reflective member, provided in said deformable member, for reflecting light emitted from said light-emitting device toward said photodetector when said first and second portions are disposed in a predetermined superposed state; and a processor which determines, based on incidence of said emitted light on said photodetector, whether or not said first and second portions are in the superposed state, and which carries out a predetermined process on a determination that said first and second portions are in the superposed state; wherein said first portion includes an upper surface and a lower surface, and the superposed state of said first and second portions includes a first superposed state, in which an upper surface of said first portion is disposed against a side of said second portion, end a second superposed state, in which a lower surface of said first portion is disposed against the side of said second portion, and wherein said deformable member allows both said first and second superposed states by deformation thereof and is connected at its lower surface to said first portion; in said first superposed state, said deformable member is present between said first and second portions.
