It is an object to provide a cellular phone capable of efficiently reducing power consumption. If a rotational position sensing part senses that a display casing has been rotated from a horizontally long state to a vertically long state, and further if a drive voltage is supplied to a TV broadcast receiving part by a drive voltage supplying part 33, and an incoming call processing part 31 performs incoming call processing, a response part 32 establishes a telephone conversion state in response to the incoming call, and a drive voltage control part 35 stops the supply of the drive voltage by the drive voltage supplying part 33. Based on this, if a call from an opposite side telephone set is made while a TV broadcast is watched, the call can be responded to only by rotating the display casing, and the supply of the drive voltage to the TV broadcast receiving part can be automatically stopped, so that power consumption can be efficiently reduced while reducing the burden of operations. |
