Abstract

PURPOSE:To prevent the error of the data processing through making the radio system possible, by taking out contents of respective response devices in order and by transmitting them to the central totaling processor by the radio or infrared-ray carrier wave. CONSTITUTION:The code signal from code generating part 33 is modulated by modulator 35 and is supplied to output stage 36 to transmit originating signal 37. This signal is received 47 in the receiving part of the response control deice and is supplied to demodulating decoder 48. Decoder 48 demodulates and decodes this signal and checks at every time whether it is coincident with the code of decoder 48 itself or not; and if they agree with each other, the pulse indicating their agreement is supplied as the gate signal to modulator 43 of the transmission part. When the gate signal is given, modulator 43 takes out the code signal of data stored in temporary memory 42 and puts this signal on a required carrier wave to send it to output stage 44. This output 45 is given as input signal 36 to central processing device 1 and is demodulated and decoded by demodulation decoder 32. Next, data is sent to totaling processing circuit part 4, and the total result of circuit 4 is sent to output display part 5.
