Abstract
An operator's actions for achieving a desired operation of a machine's actuator can be memorized in a teaching mode and the memorized information can be used for automatically reproducing the desired operation in a play back mode, to alleviate the operator's burden. A failure in the play back mode caused by the difference in the conditions under which the play back mode and the teaching mode are conducted can be eliminated, and the operation can be allowed to be continued in the manual mode even if a failure occurs in an automated operation control system. In order to achieve these, when a correction operation by the operator is detected in the play back mode, the play back mode is interrupted and the correction operation is processed with priority to the play back operation. Such correction operation is implemented by a correction signal priority circuit provided on a signal path from a signal converting device for converting the operator's operation into an electrical signal and an electronic controller for interrupting reading-out of the teaching operation data from the memory and for inputting the operator's operation to the electronic controller.
