ABSTRACT:
A portable radio terminal with an infrared communication function prevents consumption power from increasing when a radio communication function and an infrared communication function are used at a same time. A radio communication function section is judged whether in radio communication or not, and a driving current of an light emitting element in an infrared communication function section. The driving current of the light emitting element for an infrared communication is controlled in accordance with an operation of the radio communication function section, therefore, it is possible to loosen a condition for enabling infrared communication. As to restrictions for outputs from light emitting elements, a driving current of a light emitting element is controlled or plural light emitting elements having respective outputs are selectively driven.
