Abstract
The specification discloses a handheld color measurement instrument including a housing adapted to be held by a human hand. A plurality of support rollers support the housing for movement in a linear direction. A color measurement engine is contained within the housing and includes an aperture opening through the bottom of the housing. The housing includes a pair or pairs of elements defining a line parallel to the linear direction and aligned with the aperture to facilitate alignment of the instrument for scanning. The color measurement engine within the housing includes photodetectors on only one side of the aperture, enabling the aperture to be positioned adjacent the nose of the housing. The support rollers are proximate the perimeter of the housing, and an encoder wheel is inward of the support rollers and proximate the aperture. The instrument is capable of reading barcodes, for example for configuring the instrument, and of reading color samples.
