| 摘要 | A deadman switch mechanism whose safety ensuring function is hardly lost even if circuit failures such as a contact failure occur and a teaching control panel equipped therewith. When one or both of grip levers (GL1, GL2) are gripped with an ordinary force, the grip levers are swung around shafts (AX4, AX5) and shoulder parts (SD1, SD2) are engaged with driven levers (SL1, SL2), whereby both the driven levers linked with each other by means of a link (LK) are simultaneously swung around a shaft (AX3) in the direction indicated by arrow B and switches (SW1, SW2) are turned on simultaneously. Two circuits in which the switches are respectively incorporated output ON-signals independently, which are AND-processed to put a robot into an operable state. If the grips of the grip levers (GL1, GL2) are released in case of emergency, etc., the driven levers (SL1, SL2) are simultaneously swung in the direction indicated by arrow A and the switches (SW1, SW2) are simultaneously turned off to stop the robot immediately. | ||||||
