PURPOSE:To make improvements in working accuracy by digitizing an operating signal with an analog-to-digital converter in a teaching mode, having it stored in a memory, and in a playback mode, outputting it to a digital signal system. CONSTITUTION:In a teaching mode, an operator's operating signal is converted into a digital signal by an analog-to-digital converter 3a, and working machinery is controlled by this signal, while it is stored in a memory 3b. In addition, in a playback mode, the signal stored in the memory 3b in the teaching mode is taken out, outputting it to a digital signal system in the teaching mode. Consequently, these digital signals in both modes all come to such ones that have passed through the A/D converter 3a, so that working accuracy is thus improvable without entailing any error between these operating signals in both these modes. |
