Abstract
When a teach pendant is passed from one hand to the other hand in operating the teach pendant having two enable devices (three-position switches) at right and left sides, a problem arises that an operation is inhibited when the teach pendant is shifted from one hand to the other hand. Even when the three-position switches are operated by both the hands during shifting the teach pendant from one hand to the other hand, the operation can be performed Until a prescribed time passes. Thus, the teach pendant can be shifted from one hand to the other hand and can be continuously operated. When an operating time by both the hands exceeds the prescribed time, the operation is inhibited, so that a safety is ensured.
