Abstract
Based on information indicating the signal transmission amount between the first and second circuit blocks, a switching device switches an optical signal communication form which uses a first and second optical signal transmitting/receiving devices and an electric signal communication form which uses a first and second electric signal transmitting/receiving devices. Thereby, in a portable information terminal apparatus with a separate main body operation unit and a separate screen display unit, power consumed by the optical signal communication can be suppressed.
