ABSTRACT:
A transmission unit of a signal transmission device includes: a transmission-side detection unit that detects image information from an inputted electrical signal; a receiving unit that receives, from a reception unit, a status signal representing an arrival status of an outputted optical signal; and a control unit that controls an electrical-optical conversion unit on the basis of the detection result of the transmission-side detection unit and the status signal of the receiving unit so that the output of the optical signal is shut down in at least one of a case where image information is not included in an electrical signal and a case where an optical signal has not arrived.
