Abstract
An electronic notebook includes a case; a sheet-like display medium provided in the case, containing charged particles, and having a first surface and a second surface; a first electrode disposed on the case; and a second electrode disposed on the case. By changing a positional relationship between the display medium and the first electrode and the second electrode, the display medium and the first electrode and the second electrode take on either an arranged state in which the display medium is interposed between the first electrode and the second electrode so that the first surface of the display medium opposes the first electrode and the second surface of the display medium opposes the second electrode, or a non-arranged state that is a state other than the arranged state.
