WINDSHIELD FOR BALANCE
20220333975 · 2022-10-20 ·

A windshield for an electronic balance is provided which includes air cylinders incorporated inside as driving mechanisms, doors supported by a hanging manner by guide holes at least one end portion of which is open, and joint members interposed between the air cylinders and the doors. The joint members are also supported in a hanging manner in the guide holes, and upper portions of the joint members are joined to the air cylinders incorporated inside. The doors can be automatically opened and closed, and can be easily joined to and released from the driving mechanisms, and easily detached from the windshield by a simple structure.

Electronic scale displaying an object to be weighed and the measured weight of the object
11209305 · 2021-12-28 · ·

An electronic scale includes: a scale body that has a top surface provided with a weighing tray on which an object to be weighed is to be laid and a display portion which displays a weight of the object to be weighed; and a lid member that is capable of closing the top surface of the scale body and that is capable of opening and closing. A camera that images the top surface of the scale body including the weighing tray and the display portion is provided on the lid member. Alternatively, the camera is provided on the top surface of the scale body and the lid member includes reflection means that reflects an image of the top surface of the scale body including the weighing tray and the display portion toward the camera when the lid member opens, on a surface of the lid member that faces the scale body. The electronic scale is capable of simultaneously imaging the object to be weighed and the displayed weight of the same and eliminates need for a special support structure to support the camera for imaging, and the top surface of the scale body can be closed when the electronic scale is not in use.

High-precision weighing module with reduced thermal gradient

An integrated high-precision weighing module has a shell, an electromagnetic force sensor, a printed circuit board (PCB), a weighing pan component, a support ring, and an air baffle ring. The electromagnetic force sensor and the PCB are mounted in the shell. A bearing head of the electromagnetic force sensor extends upward from an upper end portion of the shell. The support ring sheathes the bearing head. The weighing pan component is mounted on the bearing head, with the support ring located between the weighing pan component and the shell. The air baffle ring is disposed around the weighing pan component and located on the support ring. A first airflow channel is formed among the shell, the support ring, and the air baffle ring. At least part of airflow in the shell flows to the outside through the first airflow channel.

Electronic balance having mechanically independent windshield
