Patent ID: 7529567

Claim:
A radio telephone apparatus, comprising: a transmission section that transmits a radio wave; a consumption section that consumes electric current; and a control section that activates the consumption section to consume the electric current during a period when the transmission section is not activated and that deactivates the consumption section during a period when the transmission section is activated, wherein the control section generates a transmission section enable signal for controlling an activation and a halt of the transmission section and a consumption section enable signal for controlling an activation and a halt of the consumption section, and wherein the control section delays a timing of transmitting the consumption section enable signal for halting the consumption section with respect to a timing of transmitting the transmission section enable signal for activating the transmission section when the control section activates the transmission section so that a change of a sum of amounts of electric currents consumed by the transmission section and the consumption section is reduced during a transition from a halting state of the transmission section to an activating state of the transmission section.
