摘要:
A produce data collector and produce recognition system which illuminates a produce item with substantially uniform light to enhance the accuracy of collected produce data and subsequent identification of the produce item as part of a transaction in a transaction establishment. The produce data collector includes a light separating element for splitting light collected from the produce item into a plurality of different light portions having different wavelengths, a detector for converting energy in the plurality of light portions into a plurality of electrical signals, and control circuitry which digitizes the plurality of electrical signals to produce a digital spectrum from the produce item which contains information to identify the produce item for the purpose of determining its unit price.

摘要:
An item checkout device (10) which combines a produce (14) data collector with an optical bar code data collector. The item checkout device includes a housing (48), a bar code data collector within the housing, and a produce data collector (14) within the housing. In a preferred embodiment, the item checkout device (10) includes an optical bar code data collector including a first housing (48), a scale within the first housing, a weigh plate (40) on the scale including a first window (56) for allowing scanning light beams from the optical bar code data collector to pass and a second window, and a produce data collector within the first housing including a second housing containing an aperture adjacent the second window (60), a light source for illuminating a produce item on the second window (60) with substantially uniform light, a light separating element for splitting light collected from the produce item into a plurality of different light portions having different wavelengths, a detector for converting energy in the plurality of light portions into a plurality of electrical signals, and control circuitry which digitizes the plurality of electrical signals to produce a digital spectrum from the produce item which contains information to identify the produce item for the purpose of determining its unit price.
