PURPOSE:To increase the effective utilization rate of an oscillation circuit, by providing a switching control circuit between an oscillation circuit and a plurality of transmission circuits and commonly using the oscillation circuit. CONSTITUTION:A switching control circuit provided commonly with transmission circuits 0 and 1 can correspond the oscillation circuit and transmission circuits one by one in time sharing manner through the assignment of transmission time, minimum pause, and period of each circuit to transmission circuits 1, 0, allowing to commonly use the oscillation circuit. |
