A protecting unit is provided. The protecting unit can prevent accidents from occurring that become problems when data are transmitted due to for instance LVDS and for instance laser light is emitted based on the data. The protecting unit is applied in an instrument comprising an input end to which differential signal is transmitted, the input end being attachable to and detachable from an input line. Here, the voltage at the input end when the input line is not connected is set to a voltage different from that generated at the input end when the input line is connected, variation of the voltage at the input end is transmitted to an input terminal of a differential input/output circuit, and the voltage at the input end or a portion corresponding thereto is compared with a prescribed voltage to fix a state of output of the differential input/output circuit to a prescribed state based on the compared results.
A protecting unit applied in an instrument comprising an input end to which a differential signal is transmitted, which is then supplied to a differential input/output circuit, the input end being attachable to and detachable from an input line, the protecting unit comprising:
