Abstract
Solar cells (5) for the supply of electric energy are located in an electronic balance in a manner suitable for the requirements of the balance and storage means for storing the electric current generated by the solar cells (5) are present. The solar cells (5) are located, for example, in a folding cover (7) which protects the balance when it is not in use and which is folded up at the start of operation. In addition, a display (9) for the state of charge of the storage means (76) is present.
Claims10
Electronic balance comprising
- a balance scale (2, 12, 32) actuable in response to electric current from a power source and providing an electrical output,
- solar cells (5, 15, 25, 35, 45, 55, 65, 75) for generating electric current and coupled to the balance scale for supplying electronic energy in a manner suitable for the requirements of the balance,
- storage means (76) connected to the solar cells are provided for storing the electric current generated by the solar cells, and
- display means (9, 80) are provided for indicating a state of charge of storage of the storage means (76).
