Abstract: A monitoring system, a monitoring device, and a monitoring method are provided. The monitoring system includes a detection part that detects a position of a worker intruded into a work area, a first specifying part that specifies a worker movable area on the basis of a position of the worker, an image capturing part that captures an image of an area including at least the worker movable area and a predetermined robot occupied area, a second specifying part that specifies a robot movable area from the image of the area, a third specifying part that specifies a human body area of the worker from the image of the area, a measuring part that measures the distance between the robot movable area and the human body area, and a restricting part that restricts movement of the robot when the distance is equal to or less than a predetermined distance.

Abstract: A monitoring system, a monitoring device, and a monitoring method that can facilitate designing of a working environment are provided. Positions of a worker and a robot in a three-dimensional space are specified, at least one protection area to secure safe work of the worker and the robot is set, whether at least one of the worker and the robot intrudes into the protection area is determined, the motion of the robot is limited when at least one of the worker and the robot intrudes into the protection area, a protection area for executing the determination is being switched from multiple set protection areas, and it is possible to set the protection area when the worker works in a common area in which a work area of the worker and a work area of the robot overlap and set the protection area when the robot works in the common area.

Abstract: A socket includes a socket body having a mounting part, and a holding lever supported on the mounting part to hold a relay mounted at a mounting position of the mounting part. The holding lever includes a support, and a stopper provided on the support and movable between a restriction position at which movement of the relay, positioned at the mounting position, in a removing direction is restricted and a restriction release position at which the restriction of the movement of the relay in the removing direction is released. The holding lever is supported on the mounting part to be movable between a retreat position at which a relay can be mounted and removed and a holding position at which a relay positioned at the mounting position can be held when the stopper is positioned at the restriction position such that the stopper covers a center-of-gravity position of the relay.
