Abstract
In the weighing apparatus, a plurality of weighing sections are connected to a main unit having a display section, and weight data from one of the weighing sections are indicated by the display section. Each weighing section has an instability detection section for detecting the instability of a weight signal. The main unit has a section by which the weight data from the weighing section whose weight signal is instable are selected on the basis of a signal from the instability detection section.
Claims10
A weighing apparatus comprising:
- a plurality of units for weighing articles and for producing weight signals and weight data, representative of said weighed articles, each of said plurality of weighing units comprising instability detection means for detecting a change in a corresponding weight signal and producing an instability signal in response thereto;
- and
- a main unit, connected to said plurality of weighing units, said main unit including:
- means for automatically selecting weight data from one of said plurality of weighing units based on instability signals from said instability detection means.
1 more element
A weighing apparatus, comprising:
- a plurality of weighing units for weighing articles and producing weight data representative thereof, each of said weighing units having means for outputting a transient signal when articles are added to the weighing unit, and
- a main unit connected to said plurality of weighing units, said main unit comprising:
- a detecting unit for alternately detecting weight data from each of said plurality of weighing units, wherein said weight data from a particular one of said weighing units is based on said transient signal output from each of the weighing units.
