<p>PURPOSE:To promptly check abnormality occurrence in an arbitrary operation by regulating an optimal supervising time for each operating part of a function part, and supervising an operating time. CONSTITUTION:A control part 11 drives operating pieces 13-1 to 13-n at every operating unit Wi according to an applied control sequence, detectors 14-1 to 14-n detect the operating states of the operating pieces 13-1 to 13-n, and output them to the control part 11. The control part 11 reads a supervising time Tsi set beforehand from a supervising time table 15, checks whether or not the execution of the operating unit Wi is completed in the supervising time Tsi, when it is not completed, the operation is decided to be abnormal, and the corresponding control is executed. Thus since the abnormal operation of the function part can be detected in an early time, and suitable steps can be taken, the damage of the function part and the generation of a defective product is effectively protected, and reliability is improved.</p> |
