PROBLEM TO BE SOLVED: To suppress the dispersion of a timing, at which a performance control board starts.SOLUTION: A power supply board 50 comprises a power generation circuit 53 for generating an external power source to be fed from the machine outside with an actuation electric power source of an electronic part disposed in a main control board 60, and an actuation electronic power source is fed to the main control board 60 and a performance control board 80 in accordance with the power activation to said power supply board 50. The main control board 60 includes a start instruction signal circuit 65 for outputting a sub reset instruction signal instructing the start of the performance control board 80. After lapse of a predetermined time period after the start of the supply of the actuation electronic power source to the main control board 60, said start instruction signal circuit means 65 outputs the subset instruction signal to the performance control board 80.SELECTED DRAWING: Figure 3 |
