There has been a problem that in the operation of a teach pendant having two enable devices (3-position switches) on the right and left sides, shifting it from one hand to the other results in prohibition of operation. In that operation is made possible until a predetermined time elapses even if the 3-position switches are operated by both hands in shifting the teach pendant from one hand to the other, shifting it from one hand to the other is allowed, making continuous operation of the teach pendant possible, while ensuring security in that when the time of operation with both hands exceeds the predetermined time, operation is inhibited.
