The invention provides a method for detecting stop of conveyor means, which detects the stop of the conveyor means, after actuated, promptly and easily without inviting any increase of parts number, so that it can improve the throughput and the operation rate. The conveyor means comprises a drive motor (3) and a conveyor arm (6) attached at its one side to the spindle (4) of the drive motor (3), so that it generates an induced electromotive force when the drive motor (3) acts the force in the rotating direction upon the spindle (4). Moreover, a conveying object (S) is held on the other side of the conveyor arm, and the drive motor (3) is activated to drive the spindle (4) rotationally by a predetermined rotation angle and then to stop it. At this time, the induced electromotive force, which is generated by the vibration of the conveyor arm (6), is detected. When the induced electromotive force detected is at or lower than a predetermined value, it is decided that the conveyor arm (6) has stopped.
