PURPOSE:To transmit specific information immediately prior to the frame just after the frame, to which the specific information belongs, in corresponding with the occurrence of the specific information, in cyclic digital information transmission, by controlling the transmission with a CPU. CONSTITUTION:The transmitting side equipment 1 of a cyclic digital information device using a microprocessor is provided with a CPU 3 and information 6 inputted from an input unit 2 is stored in and controlled by the CPU 3 and outputted to a communication circuit 7 through a transmission unit 4 and modulator 5. When the frame of the information 6 has no specific information, the information 6 is outputted to a line 7 at a prescribed cycle by the operation of the CPU 3 and, when specific information exists, the specific information is transmitted just before the next-cycle frame is transmitted. Therefore, the specific information is transmitted in a shorter time as compared with the case where the cycle is merely transmitted under a repeated condition.
