PROBLEM TO BE SOLVED: To perform normal control without any trouble in displacement display control if a pattern stop command cannot be received by a display control board when a finishing timing comes for displacement display. SOLUTION: If a pattern stop command cannot be received when a finishing timing comes for displacement display signified by a displacement pattern specifying command, the displacement display cannot be finished by a display control board. In this case, the display control board continues a display that a stop pattern specified by a stop pattern specifying command is moved forward and backward in corresponding display areas 3a1-3c3 until the pattern stop command is received from a main control board, that is, a moving display in a right-and- left rocking manner. Consequently, even if the pattern stop command cannot be received by the display control board, normal control can be performed without any trouble in displacement display control. |
