Abstract: A windshield for a balance which has a door that can be automatically opened and closed or half opened and half closed is provided. The windshield includes doors to which air cylinders are joined as driving means, sensors for monitoring movements of the doors, pressure sensors configured to monitor a pressure of air to be supplied to the air cylinders of the driving means, and a control unit configured to stop an air supply to the air cylinders when a pressure of air monitored by the pressure sensor exceeds a predetermined value. Stoppers are disposed on movement paths of the doors to block movement, and when air pressure inside the air cylinder increases to the predetermined value due to contact with the stopper, the door stops. The door can be freely fully opened and half-opened according to the position of the stopper.

Abstract: Provided is a balance with a windshield having a door to be smoothly opened and closed either manually or automatically. Provided is an electronic balance with a windshield including a balance main body including a weighing mechanism connected to a weighing pan, a windshield having doors capable of opening and closing by sliding, and configured to form a weighing chamber by covering the weighing pan, and actuators configured to open and close the doors, wherein the actuator includes a double-acting type air cylinder having two ports serving as air intake ports, an air pump-to be connected to the two ports, two valves respectively interposed between the air pump and the two ports and configured to make the ports communicate with and shut off from the atmosphere, and a control device configured to control the two valves-to make the two ports communicate with the atmosphere when the air pump is stopped. Without a special mechanism, switching between automatic opening and closing and manual opening and closing can be made, and in either automatic or manual opening and closing, the doors of the windshield are smoothly opened and closed.

Abstract: Provided is an electronic balance that includes a windshield having a door to be automatically opened and closed, and has a high degree of freedom of design. An electronic balance including a balance main body that holds a weighing mechanism connected to a weighing pan, and a windshield including a frame and doors disposed slidably on the frame, and configured to form a weighing chamber by covering the weighing pan, and configured so that the windshield includes inside air cylinders connected to the doors to open and close the doors, and air pumps to drive the air cylinders, and is configured to be detachable from the balance main body. The windshield that has doors to be automatically opened and closed is detachable from the balance main body, so that the windshield and the balance main body can be designed separately, and therefore, the degree of freedom of design of the electronic balance is high.
