Abstract
A transmission circuit includes a photocoupler, a conductive/non-conductive state of which is controlled in accordance with data to be transmitted to a communication device. A reception circuit includes a photocoupler, a conductive/non-conductive state of which is controlled in accordance with the conductive/non-conductive state of the transmission path. A transmission circuit includes a photocoupler, a conductive/non-conductive state of which is controlled in accordance with data to be transmitted to a communication device. A reception circuit includes a photocoupler, a conductive/non-conductive state of which is controlled in accordance with the conductive/non-conductive state of the transmission path. The photocoupler is included in the transmission path. The photocoupler and the photocoupler are in opposite conductive/non-conductive states.
