An automatic inspection device for a corrugated paperboard machine includes comprises a position setting section for setting movable members to positions within moving ranges; a control section for driving each of the drive motors at a given rotational speed so as to allow a respective one of the movable members to be moved within a corresponding one of the moving ranges; a current detection section for detecting a drive current being supplied to each of the drive motors when the drive motor is driven at the given rotational speed; and a current determination section for determining whether the drive current of each of the drive motors exceeds a given threshold. The automatic inspection device is configured to, when the current determination section determines that the drive current of a specific one of the plurality of drive motors exceeds the given threshold, detecting that a defect occurs in the movable member.
