A display control unit performs a control of displaying first image information on a display unit. An electric-power supply unit converts thermal energy generated from a body temperature of a user into electric power upon the user contacting the electric-power supply unit, and supplies the electric power to the display control unit. A determination unit determines whether the user is in contact with the electric-power supply unit. When it is determined that the user is not in contact with the electric-power supply unit, the display control unit performs a control of rewriting the first image information displayed on the display unit with second image information.
