Abstract: An information input device has a determination portion, a detection portion, and a switching portion. The detection portion includes two areas that plural coils are arranged along a plane. The two areas switch between a folded state facing the areas each other and a two-page spread state not facing the areas each other. When an induced current is not detected in the coils of the two areas in the continuous reception state in which the induced current of the coils can be detected, the determination portion determines that the detection portion is in the two-page spread state. When the induced current is detected in the coils of the two areas in the continuous reception state, the determination portion determines that the detection portion is in the folded state, and the switching portion switches the state of the detection portion from a normal state to a power saving state.
