The group 203 causes the power terminal group 91 of the electric disk 3 to obtain a specific timing and a stable driving voltage. The edge display circuit 80 includes a display driving chip IC5 and a display panel 81. The display panel 81 is electrically connected to the driving chip busy 5 and is exposed on the control device 2 as shown in the first 10 M323633. The IC5 is electrically connected to the power output terminal group 203 corresponding to the rectifier circuits 71, 72, 73, and 74, and the controller 10 displays the signal pin positions 16a, - 16b, 16c, and 16d of the control terminal group 16, Each of the signal pins I6a, 16b, 16c, 16d senses the drive pTi, pTi, ρτ2, PT2, 'PT3, PT3', PT4, PT4'' of the drive circuit 60 to operate the drive chip.
