The cylinder mechanism moves a tool rotation driving device to hold and rotate a tool, in a tool axis direction on an exterior of a cylinder tube using power of a piston. The positioning mechanism is connected to the cylinder tube side of the cylinder mechanism either directly or indirectly in order to position the cylinder mechanism relative to a workpiece. The holding mechanism holds the tool rotation driving device such that the power of the piston in the cylinder mechanism is transmitted to the tool rotation driving device.

Abstract: A plurality of fixed cameras installed in a driving area on a highway and a server device are connected via a network NW. The server device displays the captured images of the fixed cameras on the fixed camera monitor and requests camera position information and zooming position information to respective fixed cameras in response to occurrence of a traffic accident or the like in the driving area. In response to this request, the fixed cameras transmit the camera position information and the zooming position information to the server device. Based on camera position information and zooming position information, the server device derives the occurrence position of a traffic accident or the like, instructs a predetermined drone to capture the image around the occurrence position such as a traffic accident, and displays the captured image transmitted from the drone on a drone monitor.
