Abstract

PURPOSE:To elongate the life of a battery by making it possible to control the power source especially for a transmitting and receiving fuction portion in accordance with the output of a watch function portion. CONSTITUTION:A power source battery 1 is connected as a power source for a watch function portion 2, and a power source battery 6 is connected as the power source for a transmitting and receiving function portion 5 through a transmission gate 4. The output of the portion 2 is connected through an inverter circuit 3 with the P channel side of the gate 4 and directly with the N channel side. In case, for instance, the output of the watch function portion 2 assumes a high level, the gate 4 is rendered conductive so that the battery 6 is connected with the portion 5 to start the operations.
