This paper deals with the data-transmission system adopting the opto-electronic parts for the remote-controller of electric appliances. The signal with appropriate bit-pattern and specified wave-form is used, and the system has much longer distance nearly 1,000mm between the light-emitting-diode and the light-receiving-module than the maximum length of 3-20mm in the reported system of faster-transmission rate. Then the data-transmission from not only rotating spindle but also revolving body is realized. Three techniques, which are adoption of one-way data-transmission, one-chip micro-controller and digital-filtering process, are adopted as same as in the faster-transmission system. The data-transmissions from the end-surface of rotating spindle and from the cylindrical-surface are confirmed.
