Abstract
The cover for the weighing pan of an electronic scale is rotationally driven between closed and open positions relative to a housing by a friction drive arrangement including a clutch disc (37) and a friction disc (47). The motor drive is transmitted directly to the cover without any slippage. The cover may be rotated between its open and closed positions relative to the housing either manually (by overcoming the friction of the drive means) or by means of an electric drive motor. A control arrangement including contact fingers (19) and corresponding circular segment tracks (57) serve to monitor the position of the cover relative to the housing.
