PURPOSE:To monitor an instruction signal outputted from an instruction control part with a small number of signal terminals with an external device by coding an instruction signal outputted from the instruction control part with a coding means and outputting it to the external device through a signal output terminal as instruction data. CONSTITUTION:The title device is provided with the coding means 40 to encode an instruction signal and output instruction data and signal output terminals DO1-DO3 to output the instruction data outputted from the coding means 40 to an external device. Consequently, the instruction signal outputted from an instruction control part 2 is coded by the coding means 40 and outputted through the signal output terminals DO1-DO3 to the external device as the instruction data. Thus, with a small number of signal terminals, the instruction signal outputted from the instruction control part 2 can be monitored with the external device. |
